Also in calculus removal (Tooth Scaling), it is common to remove a calculus by attaching a scaler tip to a scaler equipped with an ultrasonic generator and vibrating the tip.

  For example, when root canal treatment is performed using a cutting tool such as a file or a reamer, the root canal to be treated is expanded by rotating or vibrating the cutting tool attached to the handpiece. In general, since the root canal is often curved, when the root canal is cut with the cutting tool, the cutting tool is bent along the root canal. When the cutting tool is rotated in this state, there is a concern that an excessive load is applied to the cutting tool and the cutting tool is damaged or the cutting tool is caught in a root canal.

  For this reason, an upper limit value is set in advance for the torque value acting on the cutting tool, and rotation or vibration of the cutting tool is performed when the torque value becomes larger than the preset upper limit value during treatment. The device is made to stop, weaken rotation or vibration, or reverse rotation.

It has to be set for each cutting tool, and when the practitioner sets a plurality of parameters, the parameters may be set erroneously.

  With respect to such a problem, Patent Document 1 (Patent Document 1) discloses an invention of a method for programming a root canal treatment handpiece having a data pack including a data set that is a parameter of the cutting tool suitable for the operation of the handpiece. No. 5479078).

  The invention disclosed in Patent Document 1 drives the handpiece by using a data set of parameters suitable for the cutting tool selected by a practitioner.

  However, the invention described in Patent Document 1 is a program for setting rotation and torque suitable for the cutting tool, and is used continuously when the medical device is used for a long time or when it is used a plurality of times. The load accumulated by doing so is not considered. Therefore, for the medical device that has been used continuously, it is necessary for the practitioner to determine that the medical device has exceeded the appropriate range based on his / her own experience and replace the medical device. was there.

It is a comparison processing unit that compares the calculated integrated load value L.

The determination processing unit 41b is a determination processing unit that determines the result of the comparison performed by the comparison processing unit 41a. In this embodiment, the determination processing unit 41b determines the magnitude of the integrated load value L and the replacement threshold T that are compared by the comparison processing unit 41a. In addition, as a result of the determination of the magnitude of the integrated load value L and the replacement threshold T, it is also determined whether or not the driving of the root canal treatment handpiece 20 to which the cutting tool 26 is attached is permitted.
In the present embodiment, the above-described determination is performed. However, the present invention is not limited to this determination. For example, only the magnitude of comparison between the integrated load value L and the replacement threshold T may be determined.

  The determination result notification unit 41c is a processing unit that operates the notification unit 16 based on the determination result obtained by the determination processing unit 41b. For example, it is controlled to output a specific sound from the audio output unit 16a by the notification method set by the notification method setting operation unit 11d, or the light output unit 16b is turned on or blinked, and the determination displayed on the notification monitor 16c. The determination result is displayed on the screen 100 (shown in FIG. 4), the vibration of the handpiece vibration unit 27 provided in the handpiece body 21 is controlled, and the rotation of the drive unit 24 is controlled by the surgical instrument drive control unit 42. can do. Furthermore, it is also possible to employ a configuration in which a plurality of these notification operations, for example, a plurality of operations such as sound generation and light emission are simultaneously activated.

  The calculation unit 41d calculates the integrated load value L acting on the cutting tool 26 based on the load coefficient C stored in the evaluation value storage unit 31, and can display the result of the determination processing unit 41b on the notification monitor 16c. It is a calculation part which performs a calculation process. Based on the cutting tool 26 recognized by the cutting tool recognition unit 23, the information reading unit 41e stores the load coefficient C necessary for calculating the integrated load value L performed by the calculation unit 41d and the replacement reference value storage unit 32. The information reading unit reads the replacement reference value E, the replacement threshold value T stored in the replacement threshold value storage unit 33, and the integrated load value L stored in the integrated load value storage unit 34.

  The surgical instrument drive control unit 42 is a control unit that drives and controls rotation, vibration, and the like of the cutting tool 26 attached to the root canal treatment handpiece 20. The surgical instrument drive control unit 42 reduces or stops the rotation of the cutting tool 26 when the detected torque value detected by the drive load detection unit 43 exceeds the set torque value set by the torque value setting operation unit 11a. In addition, when it is determined that the integrated load value L calculated by the calculation unit 41d is a predetermined value with respect to the exchange reference value E corresponding thereto, or the integrated load value L is exchanged When it is determined that the replacement threshold T set using the threshold setting operation unit 11c has been exceeded, the surgical instrument drive control unit 42 controls rotation, vibration reduction, and stop of the cutting tool 26.

  The drive load detection unit 43 is a detection unit that detects a load value applied to the root canal treatment handpiece 20 by detecting a current value flowing through the handpiece or the like. For example, a cutting attached to the handpiece or the like A detection unit that detects the number of times driving of the driving unit 24 that rotates the tool 26 is stopped, and the number of times that the cutting tool 26 is subjected to torque reverse that causes the cutting tool to reversely rotate when an excessive load is applied. You may provide the detection part to detect.

  In the present embodiment, in detecting the load torque applied to the cutting tool in the motor-driven handpiece, the drive load detection unit 43 is configured to detect the current value, but is not limited to this configuration. For example, a detection unit that detects the number of rotations per hour of the drive unit 24 that rotates the cutting tool 26 or a detection unit that detects the time required to perform a predetermined number of rotations may be used.

  The number-of-treatments detection unit 45 is a detection unit that counts the number of times of use of the root canal treatment handpiece 20 and the number of times of use of the cutting tool 26 that is used by being attached to the medical device. Specifically, the number of times of use of the root canal treatment handpiece 20 is calculated by counting the number of times of operation of each individual root canal treatment handpiece 20, and when the number of times of use of the cutting tool 26 is counted. The calculation is performed by counting the number of operations of the cutting tool 26 recognized by the cutting tool recognizing unit 23, but various counting methods such as counting operation time may be adopted without being limited to this calculation.

Next, the determination screen 100 displayed on the notification monitor 16c will be described with reference to FIG.
The determination screen 100 displays the determination result calculated by the calculation unit 41d, as well as the root canal length measurement result indicating the degree of approach to the apex Rt of the tooth D, which is the operation target, of the distal end portion of the cutting tool 26 during the operation. This is a display screen that can display the value of the detected torque value during the treatment, and is composed of an integrated load display unit 110, a root canal length measurement display unit 120, a detected torque value display unit 130, and a digital display unit 140. Yes.

  As shown in FIG. 4, the accumulated load display unit 110 is an indicator type display unit that is located on the right side of the screen of the notification monitor 16 c and indicates the ratio of the accumulated load value L to the exchange reference value E. A relative exchange reference value display unit 111 for displaying, a relative accumulated load value display unit 112 for displaying the accumulated load value L, and a relative exchange threshold value display unit 113 for displaying the exchange threshold T are configured.

  The relative exchange reference value display unit 111 is a display unit that displays the exchange reference value E after being converted as a percentage. The relative accumulated load value display unit 112 is an indicator that displays the accumulated load value L of the cutting tool 26 recognized by the cutting tool recognizing unit 23 so as to correspond to the replacement reference value E converted to a percentage.

  The relative replacement threshold value display unit 113 displays the relative replacement reference value when the three-step replacement threshold value T set / changed by the replacement threshold value setting operation unit 11c is converted so as to correspond to the replacement reference value E converted to a percentage. The position in the part 111 is displayed as a value. Here, the replacement threshold value (hereinafter referred to as “minimum threshold value T1”), which is the lowest value among the replacement threshold values T displayed on the relative replacement threshold value display unit 113, is set to 100% as the replacement reference value E. On the other hand, for example, the replacement threshold value setting operation unit 11c is set to 70%. Similarly, the replacement threshold value positioned in the middle (hereinafter, referred to as “intermediate threshold value T2”) has an exchange reference value E of 100. The replacement threshold value which is the highest position (hereinafter referred to as “maximum threshold value T3”) is set by the replacement threshold value setting operation unit 11c so as to be 80% with respect to the value of%. ing.

  These replacement threshold values T can be freely changed by operating the replacement threshold value setting operation unit 11c. Specifically, the number of replacement threshold values T can be changed to two, or the ratio to the replacement reference value E can be changed as appropriate. Further, the replacement reference value E can be changed by operating the replacement reference value changing operation unit 11b.

  As shown in FIG. 4, the root canal length measurement display unit 120 is positioned at the center of the screen of the notification monitor 16 c, and is the tip of the cutting tool 26 with respect to the root canal length of the root canal R of the tooth D to be treated. It is a display part which displays a relative position. The root canal length measurement display unit 120 includes a root canal length display unit 121 that is an indicator that displays the root canal length as a percentage, and a cutting tool position display unit 122 that displays the position of the distal end portion of the cutting tool 26 with respect to the root canal length. On the inner side of the root canal length display portion 121, a number that is a measure of how much the tip of the cutting tool 26 has reached the root apex Rt is described.

  As shown in FIG. 4, the detected torque value display unit 130 is located on the left side of the screen of the notification monitor 16c, and indicates the magnitude of the detected torque value with respect to the set torque value set by operating the torque value setting operation unit 11a. It is an indicator to be displayed, and includes a set torque value display unit 131 that displays the set torque value as 100% and a relative torque value display unit 132 that is an indicator that displays the detected torque value in accordance with the set torque value display unit 131. ing.

  As shown in FIG. 4, the digital display unit 140 is a display unit that can digitally display numbers located below the detected torque value display unit 130. The digital display unit 140 is a display unit that displays the usage status of the root canal treatment handpiece 20, and includes the temperature of the driving unit 24a, the root canal treatment handpiece 20 detected by the driving time detection unit 44, the cutting tool 26, and the like. , The detected torque value of the root canal treatment handpiece 20 detected by the driving load detection unit 43 and the rotation number of the handpiece driving unit 24 can be switched and displayed.

  Subsequently, a method of using the medical treatment system 1 when the root canal R of the tooth D to be treated is enlarged using the cutting tool 26 using the medical treatment system 1 having the above-described configuration will be described with reference to FIGS. 5 and 6. This will be described in detail based on this flowchart.

  First, in order to perform the root canal R of the tooth D to be treated, the practitioner attaches the cutting tool 26 suitable for the enlarged cutting of the root canal R to the attachment / detachment portion of the handpiece 20 for root canal treatment. In that case, the cutting tool recognition part 23 with which the handpiece 20 for root canal treatment is equipped recognizes the cutting tool 26 (step s1). In addition, the cutting tool recognition part 23 may be arrange | positioned in either the control part of the root canal treatment apparatus connected to the handpiece 20 for root canal treatment or the medical treatment system 1 separately.

Next, in setting the replacement reference value (step s2), the replacement reference value E and replacement threshold T of the cutting tool 26 recognized by the cutting tool recognition unit 23 are read from the replacement reference value storage unit 32 and the replacement threshold storage unit 33. At the same time, the starting load value Lo, which is the integrated load value L in the treatment start state of the cutting tool 26, is read from the integrated load value storage unit 34 by the information reading unit 41e (step s3).
The read replacement reference value E and replacement threshold T may be set and changed according to the cutting tool by operating the replacement reference value changing operation unit 11b and the replacement threshold setting operation unit 11c.

  The reading display by the information reading unit 41e is a value corresponding to the exchange reference value E in which the read exchange reference value E is converted to 100% and the start load value Lo is converted to 100%. It displays on the integrated load display part 110 of the monitor 16c. Further, the replacement threshold T stored in the replacement threshold storage unit 33 is also read by the information reading unit 41e, converted so as to correspond to the replacement reference value E set to 100%, and displayed on the integrated load display unit 110. .

  In addition, this treatment start state is a case where an unused cutting tool 26 is used, for example, a cutting tool 26 used for cutting a root canal, after the root canal treatment of the root canal is finished. In some cases, the same cutting tool 26 may be used to cut another root canal of the same patient.

In the former case, since the cutting tool 26 has no use history, the value of the starting load value Lo is naturally “0”.
On the other hand, in the latter case, since the accumulated load value L applied when the cutting tool 26 was used last time is accumulated, the load value Lo at the start time read from the accumulated load value storage unit 34 by the information reading unit 41e. Has a predetermined value.

Next, it is determined whether or not there is an instruction to drive the cutting tool 26 attached to the root canal treatment handpiece 20 (step s4).
When root canal treatment of the root canal R to be treated is started, that is, when it is detected that the cutting tool 26 is attached to the root canal treatment handpiece 20, but there is no drive instruction for the cutting tool 26 (step) s4: NO), the initial start load value Lo of the cutting tool 26 attached to the root canal treatment handpiece 20 and the replacement threshold T are compared, and a determination process is performed (step s8).

Here, only the comparison / determination process (step s8) will be briefly described, and the comparison / determination process (step s8) will be described in detail later.
In the comparison / determination process (step s8), a comparison process for comparing the replacement threshold T with the start load value Lo is executed, and the values of the start load value Lo and the replacement threshold T are calculated based on the result of the comparison process. A determination process for determining the size is executed. Then, the driving of the cutting tool 26 corresponding to the information obtained by the execution of the determination process and a predetermined notification method are selected.

  When it is determined that the root canal treatment handpiece 20 can be driven based on the information obtained by the comparison / determination process (step s8) (step 9: YES), that is, the starting load value Lo is at least the maximum threshold T3. If the value is lower than that, it is determined whether or not to perform the notification process based on the information obtained by the comparison / determination process (step s10).

  Specifically, when the start load value Lo is smaller than the minimum threshold value T1 in the comparison / determination process (step s8), it is determined that notification is not necessary (step s10: NO), and the notification process ( The root canal R can be treated without executing step s11) (step s12: NO).

  On the other hand, when it is determined that the starting load value Lo is larger than the minimum threshold value T1 or the intermediate threshold value T2 to be compared with the starting load value Lo, the cutting tool 26 is driven based on the result of the comparison / determination process. It is possible (step s9: YES), and it is determined that the notification process is necessary (step s10: YES). In this case, the notification operation is controlled by the determination result notification unit 41c, and the light output unit 16b is lit in green or red (step s11). Since the cutting tool 26 can be driven, the practitioner can treat the root canal R using the cutting tool 26 attached to the root canal treatment handpiece 20 (step s12: NO).

  As a result of executing the comparison / determination process (step s8), when it is determined that the starting load value Lo has a value larger than the maximum threshold value T3, the cutting tool is based on the result of executing the comparison / determination process. 26 is determined to be not possible (step s9: NO), and the determination result notification section 41c controls the notification operation to cause the light output section 16b to flash in red and to notify with a buzzer sound (step s11). ). Further, the treatment tool drive control unit 42 performs processing so as to stop or restrict the rotation or vibration of the cutting tool 26 (step s13).

  In this case, the practitioner cannot continue the treatment using the cutting tool 26, and needs to replace the cutting tool 26 in order to resume the treatment. When the cutting tool 26 is replaced, the cutting tool recognition unit 23 recognizes the replaced cutting tool 26, reads the start load value Lo of the replaced cutting tool 26 and the corresponding replacement threshold T, and performs comparison / determination processing. Are executed (steps s1 to s8). When the starting load value Lo is lower than the replacement threshold T, the root canal R can be treated (step s12: NO).

  Thus, when it is determined that the starting load value Lo is at least lower than the maximum threshold T3, the treatment can be started (step s12: NO). When a drive command is issued to start the treatment (step s4: YES), the cutting tool 26 is rotationally driven under the control of the treatment tool drive control unit 42 (step s5), and the practitioner uses the cutting tool 26. It is possible to perform root canal treatment of the tooth to be treated.

Next, the calculation process of the integrated load value Li accumulated in the cutting tool 26 during the cutting of the root canal R using the cutting tool 26, the integrated load value Li, the replacement threshold value T, and the comparison / determination process will be described.
First, the load coefficient C corresponding to the use condition of the cutting tool 26 used when operating the root canal R of the target tooth D is read from the evaluation value storage unit 31 (step s6). Next, the integrated load value Li applied to the cutting tool 26 based on the read load coefficient C is calculated by the calculation unit 41d (step s7) to calculate the integrated load value Li, and the calculated integrated load The value Li is compared with the replacement threshold T corresponding to the cutting tool 26 in the comparison processing unit 41a and the determination processing unit 41b, and the magnitude of the integrated load value Li and the replacement threshold T is determined (step s8). A method for calculating the integrated load value Li will be described later.

Since the operation after the comparison / determination process (step s8) is performed is performed in the same manner as when the start load value Lo and the replacement threshold value T are compared, a brief description will be given.
First, based on the information obtained as a result of the comparison / determination process (step s8), it is determined whether or not the root canal treatment handpiece 20 can be driven (step s9). When it is determined that the driving of 20 is possible (step s9: YES), it is determined whether notification processing is necessary (step s10).

  For example, when the integrated load value Li is smaller than the minimum threshold value T1, as described above, since there is no notification instruction, there is no need to perform notification processing (step s10: NO), and therefore the cutting tool 26 is used. Therefore, it is necessary for the practitioner to determine whether to perform the treatment as it is (step s12).

  Further, as described above, when it is determined that the integrated load value Li is at least smaller than the maximum threshold value T3, it is determined that the root canal treatment handpiece 20 can be driven (step s9: YES), and notification is made. After the process is performed (step s11) or it is determined that the notification process is not required (step s10: NO), the practitioner has not finished the root canal treatment of the root canal R that is the target of the operation. If the treatment is not finished (step s12: NO), the practitioner repeats the steps from step s5 to step s11 until the root canal treatment is finished.

When the practitioner finishes the treatment (step s12: YES), the practitioner stops driving the root canal treatment handpiece 20 and finishes the treatment.
The accumulated load value Li applied to the cutting tool 26 that has been used is stored in the accumulated load value storage unit 34 corresponding to the cutting tool 26, and the same cutting tool 26 may be used thereafter. The information reading unit 41e reads the start load value Lo from the integrated load value storage unit 34 as a start load value Lo (step s3), and the start load value Lo read during use and the replacement threshold T are compared and determined. (Step s8).

  On the other hand, when it is determined that the integrated load value Li is larger than the maximum threshold value T3, the configuration of the notification unit 16 is controlled by the determination result notification unit 41c, as in the comparison between the start load value Lo and the replacement threshold value T. The light output unit 16b flashes red and a buzzer sound is emitted from the audio output unit 16a, and a notification process is performed to control the surgical tool drive control unit 42 to stop the rotation of the cutting tool 26 (step) s13), the treatment is terminated.

  When the integrated load value Li becomes larger than the maximum threshold value T3 in this way, the driving of the root canal treatment handpiece 20 is stopped. The root canal R cannot be cut using the existing cutting tool 26, and in order to cut the root canal R, the cutting tool 26 needs to be replaced.

  In this way, the practitioner uses the medical treatment system 1 that performs the comparison / determination process between the integrated load value L and the replacement threshold T and notifies the operator based on the information obtained as a result of the comparison / determination. The cutting tool 26 can be replaced before the load due to the continuous use of 26 is deteriorated due to the accumulation of the cutting tool 26 or the like.

Next, the comparison / determination process (step s8) will be described in detail based on the flowchart of FIG.
In the following description, the integrated load value L is assumed to be either the starting load value Lo or the integrated load value Li.

  First, as described above, a comparison process is performed in which the minimum threshold value T1 that is the lowest value with respect to the replacement reference value E among the replacement threshold values T read by the information reading unit 41e is compared with the integrated load value L ( Step t1), whether or not the integrated load value L is larger than the minimum threshold value T1 is determined by the determination processing unit 41b (step t2).

  By this determination process (step t2), when the determination processing unit 41b determines that the integrated load value L is smaller than the minimum threshold T1 (step t2: NO), the cutting tool 26 can be driven to rotate. At the same time as making the determination, the comparison determination process is terminated without giving a notification instruction or the like.

  On the other hand, when the determination processing unit 41b determines that the integrated load value L is larger than the minimum threshold value T1 (step t2: YES), the intermediate threshold value T2 and the integrated load value read from the replacement threshold value storage unit 33 by the calculation processing unit 41 A comparison process for comparing L is performed (step t3), and a determination process for determining the magnitude of the integrated load value L and the intermediate threshold value T2 based on the comparison is performed (step t4).

When it is determined by the comparison processing unit 41a that the integrated load value L is smaller than the intermediate threshold value T2 (step t4: NO), the determination that the cutting tool 26 can be driven is made based on the information obtained as the determination result. At the same time, the notification instruction 1 which is information for instructing the light output unit 16b to emit green light is output (step t8), and the comparison / determination process ends.
Based on the information output in this way, as described above, the determination result notification unit 41c performs a notification process (step s11).

  If it is determined in step t4 that the integrated load value L is greater than the intermediate threshold value T2 (step t4: YES), the maximum threshold value T3 read from the replacement threshold value storage unit 33 and the integrated load value L are compared. The comparison processing to be compared by the unit 41a is executed (step t5), and the determination processing to determine the magnitude of the value is executed by the determination processing unit 41b (step t6).

  When it is determined that the integrated load value L is smaller than the maximum threshold value T3 as a result of the comparison process and the determination process between the maximum threshold value T3 and the integrated load value L performed in steps t5 and t6 (step t6: NO), based on the information obtained in the determination, a determination is made that the cutting tool 26 can be driven, and at the same time, notification that is information for instructing the light output unit 16b to light the light output unit 16b in red Instruction 2 is output (step t9), and the comparison / determination process ends.

  On the other hand, when the determination processing unit 41b determines that the integrated load value L is large by comparing the integrated load value L with the maximum threshold value T3 (step t6: YES), the notification instruction 3 is output (step t7). The comparison / determination process ends.

This notification instruction 3 is information indicating that driving of the cutting tool 26 cannot be permitted. In addition, the light output unit 16b that is the configuration of the notification unit 16 using the cutting tool 26 blinks in red, and a buzzer sound is generated from the audio output unit 16a that is the configuration of the notification unit 16, and further, the surgical instrument drive control unit 42 is information instructing to stop the rotation or vibration of the cutting tool 26.

Next, a method for calculating the integrated load value Li using the load coefficient C shown in FIG. 7 will be briefly described.
The integrated load value Li is set to an integrated load value under a standard use condition (hereinafter referred to as “reference integrated load value Lb”), and a load coefficient under a predetermined use condition with respect to the reference integrated load value Lb. It can be obtained by multiplying C (see FIG. 7).

  For example, FIG. 7 shows a calculation example of the integrated load value Li when the root canal R is treated using the cutting tool 26a. In the upper, middle, and lower tables in FIG. 7, the cutting speed 26a, 26b, and 26c having different shapes from the upper table are obtained by changing the number of rotations, the set torque value, the number of torque reverses, and the like in the leftmost column of each table. The example of the calculation table of the load coefficient C in the case is shown.

  As a premise, the criterion of the evaluation value in each use condition of the cutting tool 26a shown in the upper part of the table of FIG. 7 is the leftmost condition of FIG. That is, this is a case where the set rotational speed is 50 rpm, the set torque value is 0.2 N · cm, the usage time is 1 minute, and the number of torque reverses is 0. The reference integrated load value Lb in this case is “1.00”. Since this use condition is used as a reference, the load coefficients C for obtaining the load value acting on the cutting tool 26a are all “1” under this use condition (see the upper part of FIG. 7).

  Next, a case where the root canal R is cut using the cutting tool 26a under the following use conditions will be considered based on the use conditions of the cutting tool 26a shown in the upper part of the table of FIG. For example, the usage conditions are a set rotation speed of 100 rpm, a set torque value of 0.4 N · cm, and a rotation time of 1 minute.

  In this case, the load coefficient C with respect to the set rotational speed is “1.4”, the load coefficient C with respect to the set torque value is “1.8”, and the load coefficient C with respect to time is “1.0” (see the upper part of FIG. 7). ), The integrated load value Li acting on the cutting tool 26a under this use condition is calculated as “1.00 × 1.4 × 1.8 = 2.52”.

  For example, the curvature of the root canal R to be treated is set to 500. In this case, a load is applied to the cutting tool 26a during the cutting as compared with the case where the curvature of the root canal is ∞, that is, the root canal is straight. Therefore, when the root canal curvature is 500, the load coefficient C is a value larger than “1.0”.

  Since the load coefficient C when the curvature of the root canal R is 500 is “1.2” (see the upper part of FIG. 7), it acts on the cutting tool 26a when the root canal R is cut with the cutting tool 26a. The integrated load value Li is a value obtained by multiplying the integrated load value Li obtained above by “1.2”. That is, the integrated load value Li is “2.52 × 1.2 = 3.02.”

The integrated load value Li calculated in this way is further calculated for each use condition, and by adding these values, the load acting on the cutting tool 26 can be calculated.
For example, if the cutting tool 26a is used as it is after the above use conditions and further cutting is performed on the curved apex side, for example, the set rotation speed is 50 rpm, the set torque value is 0.4, and the rotation time is Assuming 5 minutes and a curvature of 300, the integrated load value Li is “16.20”, and the integrated load value Li acting on the cutting tool 26a is “19.22”, which is the total.

  As described above, the reference integrated load value Lb in the reference use condition is stored in the replacement reference value storage unit 32, and the load coefficient C corresponding to each use condition is stored, so that the cutting tool can be used under a predetermined use condition. 26 can be calculated from the reference integrated load value Lb and the load coefficient C.

  Note that the load coefficient C displayed in FIG. 7 indicates that each cutting tool 26 is used as a root canal treatment handpiece when cutting a root canal (a root canal that is artificially created to obtain an evaluation value), for example. It may be obtained experimentally by changing the usage conditions and performing the treatment, or by calculation based on the material and diameter of the cutting tool 26.

  Further, in the present embodiment, the integrated load value Li is obtained by multiplying the reference integrated load value Lb under the reference use condition by the load coefficient C corresponding to each use condition, but this method is limited. For example, there is a method of calculating an integrated load value (hereinafter, “calculated integrated load value Lc”) based on the detected torque value detected by the drive load detecting unit 43 and the drive time detecting unit 44 and the drive time.

For example, consider a case where the cutting tool 26 is mounted on the root canal treatment handpiece 20 and the root canal R of the tooth D to be treated is cut (see FIG. 8).
In general, the shape of the root canal R is curved on the apical side as shown in FIG. Here, since the root canal R is not curved in the vicinity of the root canal, the load value detected by the drive load detector 43 when the root canal near the root canal is cut with the cutting tool 26 is a low value. It becomes.

  Next, as the cutting of the root canal R progresses, the diameter of the root canal R becomes thinner and curved (see FIG. 8A), so the moment acting on the cutting tool 26 detected by the drive load detector 43. A typical load value increases as cutting progresses, that is, as time progresses.

  In this way, when the root canal R is advanced and the tip of the cutting tool 26a reaches the root apex Rt, the cutting tool 26a is rotated backward, for example, and slowly extracted from the root canal R. The load value detected by the load detection unit 43 becomes lower as it approaches the root canal opening. The detected load value is stored in the load value storage unit 35 every time.

In addition, when the change for every time of the load torque value detected by the drive load detection unit 43 is visualized so as to be easily understood, a graph as illustrated in FIG. 8B is obtained.
In the graph of FIG. 8B, when the load torque value detected by the drive load detection unit 43 for each hour and stored in the load value storage unit 35 is the vertical axis, and the time is the horizontal axis, the load torque value Represents the change over time.

  By integrating the load torque value detected by the drive load detection unit 43 with the drive time detected by the drive time detection unit 44 as described above, the calculated integrated load value Lc applied to the cutting tool 26a can be calculated. By calculating the calculated integrated load value Lc and making a determination in comparison with the threshold value T (step s9), it can be notified whether or not the cutting tool 26a is used within an appropriate range.

  When torque reverse occurs in the cutting tool 26 due to an excessive load acting on the cutting tool 26, as shown in FIG. 8B, the load value is determined based on the set torque value. It will decrease rapidly from the value. In this case, since an overload is acting on the cutting tool 26, an overload such as torque reverse can be dealt with by multiplying the calculated integrated load value Lc by a predetermined coefficient.

  Further, in the present embodiment, displaying the graph as shown in FIG. 8B by performing the calculation process in the calculation unit 41d is not performed because the processing load increases, but for example, the monitor 15 or the notification monitor It is good also as a structure which displays such a graph in 16c. Further, such a graph may be stored in the integrated information storage unit 34.

  As described above, the driving load detection unit 43 that detects the load value acting on the cutting tool 26 during the treatment in the mouth, the driving time detection unit 44 that detects the driving time of the cutting tool 26, and the driving load detection unit 43. A load value storage unit 35 for storing the detected load value (see FIG. 1), and by using an evaluation formula for accumulating the load value detected based on the time detected by the drive time detection unit 44, The calculated integrated load value Lc can be calculated.

  Thus, by calculating the integrated load value Li using the evaluation formula, the drive load detection unit 43 detects the change over time of the load value acting on the cutting tool 26, and the cutting value 26 is accumulated by accumulating the load value. It is possible to accurately obtain the calculated integrated load value Lc acting on the.

  Specifically, when performing root canal treatment using the cutting tool 26 used for root canal treatment as described above, the load acting on the cutting tool 26 changes over time depending on the shape of the root canal R and the like. However, the load value that changes with time can be detected by providing the drive load detector 43.

  Then, by accumulating the load value detected by the drive load detection unit 43 with the drive time detected by the drive time detection unit 44, by using the cutting tool 26 on which the load value that changes every moment acts for a predetermined time, The calculated integrated load value Lc acting on the cutting tool 26 can be accurately calculated.

  Furthermore, even when the control unit 40 does not have the drive time detection unit 44, the drive load detection unit 43 is configured to detect the load value at regular intervals, so that these values are accumulated. A calculated integrated load value Lc (hereinafter referred to as “accumulated integrated load value La”) can be calculated.

Specifically, the drive load detection unit 43 detects the load value at regular intervals and stores it in the load value storage unit 35. The accumulated load value La can be calculated by accumulating the stored load values.
In order to make it easy to imagine the cumulative accumulated load value La described above, FIG. 9 is a graph in which the vertical axis represents the load value detected by the drive load detector 43 at regular intervals and the horizontal axis represents the time axis. .

  In this way, the practitioner has the drive load detection unit 43 that detects the load value for each time of the cutting tool 26, and thus accumulates the load value detected by the drive load detection unit 4343, thereby accumulating the accumulated cumulative load value La. Can be calculated accurately. Thus, the practitioner can accurately grasp the accumulated cumulative load value La, and can accurately determine the replacement time of the cutting tool 26.

Further, the ratio of the accumulated load value Li to the exchange reference value E is displayed on the accumulated load display unit 110 displayed on the notification monitor 16c, so that the practitioner can roughly grasp the replacement time of the cutting tool 26 used by the practitioner. can do.
The integrated load value displayed on the integrated load display unit 110 is not limited to the integrated load value Li calculated based on Table 7, and the above-described calculated integrated load value Lc, accumulated integrated load value La, and the like are used. May be.

  Specifically, since the integrated load value Li that has acted on the cutting tool 26 increases based on the use of the cutting tool 26, the relative integrated load value display unit 112 that displays the ratio of the integrated load value Li sets the replacement reference value. The relative exchange reference value display unit 111 to be displayed increases. Thereby, the practitioner can visually recognize that the relative integrated load value display unit 112 is in the vicinity of the relative replacement threshold value display unit 113. Therefore, the practitioner can roughly grasp the replacement time of the cutting tool 26 used by the practitioner.

  Further, in addition to displaying the ratio of the integrated load value Li to the replacement reference value E on the integrated load display unit 110, the determination screen 100 displays the relative position of the tip portion of the cutting tool 26 relative to the root canal length and the set torque value. By displaying the detected torque value on the root canal length measurement display unit 120 and the detected torque value display unit 130, it can be used as a material for determining whether or not the cutting tool 26 should be replaced.

  Specifically, when the rate of increase of the accumulated load value Li with respect to the replacement reference value E displayed on the accumulated load display unit 110 is large, the load acting on the cutting tool 26 is large, and thus the root canal that is the target of the treatment. It can be judged that it is not suitable for performing R. In this case, the practitioner can replace the cutting tool 26 with a smaller load on the root canal R, specifically, the cutting tool 26 having a smaller diameter than the cutting tool 26 being used.

  As described above, the medical care system 1 functioning as a notification device includes an integrated load value L obtained by integrating the load values acting on the cutting tool 26, and an exchange reference value E or an exchange threshold value T set in advance for the medical device. A comparison processing unit 41a and a determination processing unit 41b that determine by comparing them, and a notification unit 16 that notifies by a predetermined operation specified by the determination result notification unit 41c based on the results determined by the comparison processing unit 41a and the determination processing unit 41b When the cutting tool 26 is used beyond the range of the replacement threshold T, the use exceeds the range of the replacement threshold T of the cutting tool 26. Can be notified.

  More specifically, for example, when the practitioner operates the patient's root canal R using the cutting tool 26, the integrated load value L obtained by calculating the load value acting on the cutting tool 26 and the replacement threshold T of the cutting tool 26. To determine whether or not the integrated load value L is larger than the replacement threshold T. That is, not only the temporary overload that acts on the cutting tool 26 but also the accumulated load value L that acts on the cutting tool 26 when the cutting tool 26 is used for a long time or when it is used a plurality of times is greater than the replacement threshold T or the like. Whether it is large or not can be determined.

Further, based on the result of this determination, the operator can be notified of the determination result of the integrated load value L and the replacement threshold T by performing a predetermined operation.
Specifically, when the integrated load value L exceeds the replacement threshold T, becomes equal, or reaches a predetermined ratio with respect to the replacement reference value E, a buzzer sound, a melody, or lighting of light The practitioner can be notified by display on the display unit, vibration, or the like. Further, the integrated load value L and the replacement reference value E can be displayed on the monitor 15 and the notification monitor 16. Thereby, the practitioner can recognize whether or not the integrated load value L is larger than the replacement threshold T even when the cutting tool 26 is used for a long time or used a plurality of times. .

  Therefore, for example, when it is notified that the integrated load value L has exceeded the replacement threshold T, the practitioner can replace the cutting tool 26 before problems such as breakage of the cutting tool 26 occur.

  In the present embodiment, the integrated load value L accumulated in the cutting tool 26 is obtained and compared with the replacement threshold T. For example, the above-described notification device and the cutting tool 26 used for treatment can be attached and detached, A medical treatment system 1 including a root canal treatment handpiece 20 including a drive unit 24a capable of driving the cutting tool 26, and a surgical instrument drive control unit 42 that controls at least driving of the root canal treatment handpiece 20; can do.

  In addition, the medical system 1 includes the cutting tool recognition unit 23 that recognizes the cutting tool 26 and the replacement reference value storage unit 32 that stores the replacement reference value E of the cutting tool 26 recognized by the cutting tool recognition unit 23. Before the treatment, the cutting tool 26 used by the practitioner can be individually recognized, and the replacement reference value E of the recognized cutting tool 26 can be called from the replacement reference value storage unit 32. Therefore, the replacement reference value E corresponding to the cutting tool 26 used by the practitioner, the replacement threshold value T corresponding to the replacement reference value E, and the integrated load value L of the cutting tool 26 can be reliably compared.

Furthermore, since the replacement reference value E stored in the replacement reference value storage unit 32 includes the replacement reference setting operation unit 11b and the replacement threshold setting operation unit 11c that can be changed within a predetermined range, the practitioner can perform a predetermined operation. The exchange reference value E can be changed within the range.
This makes it possible to appropriately reflect, for example, a treatment preference with an emphasis on safety, a treatment habit of each individual practitioner, a practitioner's treatment method, and the like.

  For this reason, the alerting device and handpiece which improve satisfaction can be provided to a practitioner.

  Furthermore, based on the evaluation information, the calculation unit 41d calculates the integrated load value L based on the evaluation information for evaluating the load value acting on the cutting tool 26 corresponding to the use condition of the cutting tool 26. The integrated load value L corresponding to the difference in use conditions of the cutting tool 26 can be calculated. Therefore, the integrated load value L in consideration of the use conditions can be obtained, and it can be determined whether or not the integrated load value L calculated corresponding to the use conditions exceeds the replacement threshold T. For this reason, the practitioner can appropriately replace the cutting tool 26 according to the use conditions.

  Furthermore, by providing the evaluation value storage unit 31 for storing the evaluation information, the evaluation information corresponds to each preset usage condition of the cutting tool 26, and is set as a load coefficient C for evaluating the load value. The integrated load value L corresponding to the use condition of the cutting tool 26 can be calculated simply and with a required accuracy, and the processing load for calculating the integrated load value L can be reduced.

  Specifically, according to the configuration of the present embodiment, a load coefficient C set in advance corresponding to individual use conditions such as a set torque value and the number of times of use set when the cutting tool 26 is used is stored as an evaluation value. It can be stored in the part 31. Since the integrated load value L can be calculated based on a preset load coefficient C corresponding to the use conditions, the processing load for calculating the integrated load value L can be reduced, and the integrated load value can be reduced. L can be calculated simply and with required accuracy, and it can be determined whether or not the integrated load value L calculated with the required accuracy exceeds the replacement threshold T. Therefore, the practitioner can determine the replacement time of the cutting tool 26 with required accuracy based on the determination result.

  Furthermore, by including the integrated load value storage unit 34 for storing the integrated load value L, it is possible to use the cutting tool 26 within the range of the replacement reference value E in consideration of usage modes including past use. It can be notified whether or not.

  More specifically, by providing the integrated load value storage unit 34 for storing the integrated load value L, the integrated load value L of the cutting tool 26 when used in the past can be stored. Therefore, even when the cutting tool 26 is used a plurality of times, the accumulated load value L at the previous use is read from the accumulated load value storage unit 34, and the accumulated load value L is accumulated with respect to the accumulated load value L. Can be calculated.

  Thereby, the accumulated load value L obtained by accumulating the load value with respect to the past accumulated load value L and the replacement threshold T can be compared and determined, and the cutting tool 26 is also considered in consideration of the usage mode including the past use. It is possible to notify whether or not the use of is within the range of the exchange reference value E.

Furthermore, by providing the notification unit 16 with a sound output unit 16a capable of outputting sound, a light output unit 16b capable of emitting light, and a notification monitor 16c capable of displaying the determination result, sound or light such as a buzzer sound or a melody is displayed. Can be notified by a method such as blinking or turning on or displaying the determination result on the notification monitor 16c, so that the practitioner compares the integrated load value L with the replacement threshold value T by visual or auditory sense. Can be recognized.
Thereby, the practitioner can recognize the replacement time of the cutting tool 26 visually or by hearing.

  In addition, since the handpiece vibration unit 27 and the determination result notification unit 41c are provided, when a predetermined condition, for example, the integrated load value L acting on the cutting tool 26 exceeds the replacement threshold value T, for root canal treatment. The handpiece 20 can be vibrated and the effect can be left for the practitioner. Thereby, the practitioner can recognize by experience that the integrated load value L has exceeded the replacement threshold value T.

The scaler integrated load display unit 110b, which is an indicator showing the ratio of the integrated load value L to the lower part of the figure, shows the relative position of the scaler chip 76 relative to a preset work length on the lower side in the figure. A display unit 120b is arranged, and a scaler operation unit 150b for performing a predetermined operation of the scaler is displayed on the rear end side of the scaler determination screen 100b.

  Note that the scaler operation unit 150b includes a torque value setting operation unit 11a, an exchange reference value setting operation unit 11b, and an exchange threshold setting operation unit 11c, similar to the handpiece operation unit 150a included in the root canal treatment handpiece 20a. The setting operation is accepted.

  In the medical care system 1, the notification unit 16 is an embodiment provided in the operation panel 102 (see FIG. 2), but an embodiment provided in the root canal treatment handpiece 20 a and the calculus removal scaler 70 (FIG. 11 and FIG. 11). For example, only the notification monitor 16c of the notification unit 16 may be provided in the root canal treatment handpiece 20 (not shown).

In this way, by providing the notification monitor 16c in the root canal treatment handpiece 20, the cutting attached to the root canal treatment handpiece 20 by the notification monitor 16c provided in the root canal treatment handpiece 20 at hand. The practitioner can confirm how much the accumulated load value L of the tool 26 has accumulated with respect to the replacement reference value E without looking at the image displayed on the operation panel 102 or the monitor 15.
Note that the notification monitor 16c provided in the root canal treatment handpiece 20 may display not only the integrated load value L but also information on the root canal length as shown in FIG.

  In addition, the notification unit 16 including the notification monitor 16c may be provided in the root canal treatment handpiece 20, the calculus removal scaler 70, the operation panel 102, the root canal treatment device 60 with a notification function, and the like. However, it is not necessary to be provided in all of these devices, and may be configured to be provided only in a notification device configured as a separate body, or at least one of the devices.

  Moreover, this invention is equipped with the above-mentioned alerting | reporting apparatus, the treatment tool used for treatment, and the handpiece main body 21 which can drive a treatment tool, The cutting tool 26 can be attached or detached to the handpiece main body 21. It has a detachable part, a drive part 24a for driving the cutting tool 26 mounted on the handpiece body 21, and a surgical instrument drive control part 42 for controlling the drive part 24a. The cutting tool 26 is used as a surgical tool, The notification unit 16 can be the root canal treatment handpiece 20 configured by the surgical instrument drive control unit 42.

According to the present invention, the surgical tool drive control unit 42 can control the driving of the surgical tool based on the result obtained by comparing the integrated load value L applied to the cutting tool 26 with the replacement reference value E.
Thereby, when the integrated load value L becomes a predetermined value with respect to the replacement reference value E, the driving of the surgical tool can be attenuated or stopped. Therefore, the practitioner can accurately determine the replacement time of the surgical tool and replace the surgical tool.

  As another embodiment, as shown in FIG. 12, a determination screen 100 displayed on the notification monitor 16 c of the medical treatment system 1 is provided at the rear end of the handpiece body 21 that is the body portion of the root canal treatment handpiece 20. It can be set as the structure provided with the display part to display.

  Furthermore, in the present embodiment, when comparing the start load value Lo or the accumulated load value Li and the replacement threshold T (steps s4 and s9), first, the accumulated load value L and the minimum threshold T1 are compared. After the determination, the determination is made by sequentially comparing the intermediate threshold value T2 and the maximum threshold value T3. However, the determination is not limited to this order. For example, the intermediate threshold value is first determined after comparing the integrated load value Li with the maximum threshold value T3. It is good also as a structure compared with T2.

  With such a configuration, it can be determined whether the root canal R can be cut using the cutting tool 26 attached to the root canal treatment handpiece 20, and if the cutting tool 26 cannot be used, The burden of processing required for notification can be reduced.

  For example, the root canal treatment handpiece 20 and the calculus removal scaler 70 need to be sterilized using an autoclave due to hygiene problems. However, since the autoclave keeps medical devices such as the root canal treatment handpiece 20 under high temperature and high pressure conditions for 10 minutes or more, it causes a load on the medical devices such as the root canal treatment handpiece 20. It will be. Naturally, surgical tools such as the cutting tool 26 and the scaler tip 76 are also loaded when sterilized by an autoclave.

Predetermined Therefore, when the medical device such as a root canal treatment handpiece 20 and treatment tool digits autoclaved, in order to accumulate the load exerted by the digits multiplied by autoclave, corresponding to the number of autoclave It is necessary to calculate the integrated load value Li by multiplying the start load value Lo by the load coefficient C.

  For this reason, even if the previous integrated load value Li is lower than the maximum threshold value T3, the integrated load value Li exceeds the maximum threshold value T3 by applying the autoclave, and the determination result (step s4) In some cases, the rotation cannot be performed by 20 and treatment cannot be performed (step t10).

  It is assumed that a new load is applied to medical devices such as the root canal treatment handpiece 20, the calculus removal scaler 70, and the cutting tool 26 after the previous treatment, such as sterilization. In such a case, in the comparison and determination (step s4), notification is made by first determining whether or not the medical device such as the root canal treatment handpiece 20, the scale removal scale 70, and the cutting tool 26 can be used. It is possible to reduce the processing burden required for the process.

  In the present embodiment, the root canal treatment handpiece 20 displays the notification form by sound, visual notification by light, and the usage status such as the integrated load value L and the replacement reference value E on the display screen. Although it is set as the structure of making it vibrate by providing the handpiece vibration part 27 in this, the structure of these single-piece | units may be sufficient and you may alert | report combining several.

  Furthermore, for example, the usable time of the cutting tool 26 is calculated backward from the usage conditions such as the integrated load value L and the exchange reference value E acting on the cutting tool 26 used for cutting the root canal R, and a notification monitor is provided. It is good also as a structure of displaying the standard of usable time on 16c.

Further, in the present embodiment, the notification result is displayed on the notification monitor 16, but may be displayed on the monitor 15.
Specifically, by operating the pedal 14a, information regarding the integrated load value L displayed on the notification monitor 16c may be switched to the monitor 15 and displayed simultaneously with other images. Alternatively, the display may be enlarged and displayed by operating the pedal 14a or the like.

  Furthermore, in the above configuration, the notification unit 16 is configured by the audio output unit 16a, the light output unit 16b, and the notification monitor 16c. The treatment device 60, the root canal treatment handpiece 20a, and the like are not necessarily provided with all of them. For example, only the audio output unit 16a or only the notification monitor 16c may be provided, and the audio output unit 16a may be provided. The optical output unit 16b and the notification monitor 16c may be provided with two of them. Furthermore, it is good also as a structure provided with these one or two and the handpiece vibration part 27. FIG.

  Further, in addition to the configuration of the present embodiment, for example, when the detected load value detected by the drive load detector 43 exceeds the set torque value, the driving of the cutting tool 26 is reversed or the driving force is reduced, The structure which stops can be provided. Thereby, for example, when a temporary overload acts on the cutting tool 26 during root canal treatment, the driving of the cutting tool 26 can be controlled, and the treatment can be performed more safely.

  In the description of the present embodiment, the example of the root canal cutting tool and the cutting tool for the scaler has been described. However, the present invention is not limited to this, and for air turbine handpieces and micromotor handpieces. It may be a cutting bar or a laser irradiation chip for medical laser hand heat, and can be widely applied to cutting tools for handpieces for bone surgery and micromotor handpieces.
