Preferred embodiments of the present disclosure are further elaborated below in conjunction with the drawings of the present specification.
In the following embodiments, embodiments of a control method of a medical observation system are described. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a medical viewing system according to an embodiment of the present application. The medical observation system includes an endoscope 1, a main body 4, and a connection wire 3 electrically connecting the endoscope 1 and the main body 4. The connection line 3 transmits signals between the two. The signal transmission direction may include a control signal transmitted from the host computer 4 to the endoscope 1, or may include an image signal transmitted from the endoscope 1 to the host computer 4, an operation state feedback signal of the endoscope 1, and the like. The connecting wire 3 specifically comprises a first communication interface 31, a cable part 33, an electric communication duration recording module, a display module 32 and a controller. The electrical communication duration recording module is used for recording and updating the electrical communication duration between the endoscope 1 and the first communication interface 31. The display module 32 may be used to display the electrical communication time recorded by the electrical communication time recording module, or the remaining use time of the endoscope 1, or to display the operation state information of the endoscope 1, or the like.
A structural example of the endoscope 1 will be first described. The endoscope 1 of the present embodiment may be a disposable endoscope 1 or may be an endoscope 1 in which the insertion portion 11 is used a limited number of times. Wherein, the disposable endoscope 1 is disposed of from the polluted part after use, so that the sanitation degree of the endoscope 1 can be improved, and the safe use of a subject can be ensured. Both the handle 12 and the insertion portion 11 are contaminated during use, and therefore both the handle 12 and the insertion portion 11 need to be discarded to ensure safe use of the endoscope 1. The endoscope 1 in which the insertion portion 11 is used a limited number of times can be used several times for the insertion portion 11, and can be used next time after each use is sterilized, but the total number of uses is limited.
Referring to the drawings, there is shown a schematic structural view of an insertion tube according to an embodiment of the present application. A structural example of the endoscope 1 will be first described.
The handle 12 of the endoscope 1 is shaped to be held by an operator's hand and to be operated with force. The insertion portion 11 includes an insertion tube and a bent portion 13. The front end of the insertion tube is provided with a bend 13. From the handle 12 there extends a traction wire (not shown) which is connected in driving connection with the bending portion 13 through the insertion tube. The bending portion 13 is provided with a plurality of snake bone structures rotatably connected to each other. The snake bone structure can rotate freely. The inside wall of the snake bone structure is provided with a guide groove, and the traction wire passes through the guide groove to be in traction connection with the snake bone structure. When the traction wire is pulled at the handle 12, the snake bone structure is driven to rotate or bend, so that the bending direction and the bending angle of the bending part 13 connected with the other end of the traction wire can be controlled. The bending part 13 is bent and extended into the cavity, so that the insertion tube is guided to move in the cavity. The handle 12 is provided with a control knob. The control knob is connected with the traction wire, and the traction wire is pulled and moved by rotating the control knob. The control knob may be a plurality of handwheels. The plurality of hand wheels are coaxially arranged up and down. The finger of the operator can be moved.
Corresponding gas-liquid delivery pipes in the pipes of the insertion portion 11, power supply lines for transmitting image signals and image transmission lines for supplying power, and other signal lines for controlling and detecting. An image acquisition module and an illumination optical module are provided at the front end of the curved portion 13. The image acquisition module may include a CCD, CMOS, or other imaging device. The image acquisition module is used for acquiring image information in the cavity of the subject, and transmitting image signals to the host 4 through the image transmission line so as to enable an operator to diagnose and treat the subject according to the image information. The bending portion 13 is further provided with an observation window, an air supply nozzle, and a water supply nozzle. The gas and liquid delivered by the gas-liquid delivery pipeline are correspondingly sprayed out from the gas delivery nozzle and the water delivery nozzle so as to clean the surface of the observation window. Control buttons are also provided on the handle 12. The control button is electrically connected with the pump set of the endoscope 1. The pump set of the endoscope 1 is used for pumping gas or liquid or the like into the gas-liquid conveying pipeline for the use of the endoscope 1 during the use process. The control button can control the working state of the pump group. The operating state of the pump unit may include switching of the pump unit, adjustment of parameters, etc.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling a medical viewing system according to an embodiment of the present application. In one embodiment, a method of controlling a medical viewing system includes:
s51, after the host computer 4 is electrically communicated with the endoscope 1, acquiring the electric communication duration between the endoscope 1 and the connecting wire 3;
s52, if the electric communication duration of the endoscope 1 is smaller than or equal to the reference duration, updating the electric communication duration between the endoscope 1 and the connecting wire 3 based on the electric communication duration;
And S53, when the electric communication time length reaches the preset limit use time length, the communication connection between the endoscope 1 and the host computer 4 is cut off.
In the solution of this embodiment, the used time of the endoscope 1 is determined by recording the electric communication time of the endoscope 1, and when the electric communication time reaches the preset limit use time, the communication connection between the endoscope 1 and the host 4 is cut off to prevent the endoscope 1 from being used continuously, so as to achieve the purpose of preventing secondary use, so that the solution of this application improves the use safety of the endoscope 1.
And can further mark that the endoscope 1 has been used while the electrically connected time period reaches a preset limit use time period, so that when the endoscope 1 is reused after being disconnected from the host computer 4, the connection wire 3 or the host computer 4 can recognize the mark, thereby cutting off the communication between the endoscope 1 and the host computer 4, and achieving the purpose of preventing secondary use.
In step S51, one end of the connection wire 3 has a first communication interface 31 for plugging with a handle interface on the handle 12 of the endoscope 1 to realize electrical connection, and the other end of the connection wire 3 has a second communication interface for electrical connection with the host 4. When the two ends of the connecting wire 3 are respectively and electrically connected with the handle interface of the endoscope 1 and the host 4, the host 4 is electrically communicated with the endoscope 1.
In step S51, a historical electrical communication time period between the endoscope 1 and the connection wire 3 is acquired, and if the acquired electrical communication time period reaches a reference time period, it is determined that the endoscope 1 has been used. The reference time is far less than the limit use time. This use has a secondary use risk, so the alarm information can be displayed by the display module 32, or the operator can be reminded by other alarm modes. Here, the controller in the connection line 3 may issue an interrupt communication command to the host computer 4 to stop the host computer 4 from receiving the signal transmitted from the endoscope 1, so that the endoscope 1 is strictly prevented from being used. The host computer 4 can also acquire the recording result of the electric communication duration recording module, and stop receiving the signal sent by the endoscope 1 or send out an alarm. The present embodiment thus improves the safety of use of the endoscope 1.
The connection wire 3 or the host computer 4 cuts off the communication with the endoscope 1 to avoid secondary use. Here, the reference time period is generated by the electrical connection operation which is inevitably present before the endoscope 1 is used for the operation due to the production or test requirements. The reference time period may be set to 0, or any finite time period greater than 0.
Therefore, if the acquired electrical communication time period between the endoscope 1 and the connection wire 3 is less than or equal to the reference time period, this indicates that the endoscope 1 is not used, there is no risk of secondary use, and thus can be used for the current operation. If the acquired electrical communication time between the endoscope 1 and the connecting wire 3 is longer than the reference time, the endoscope 1 may be used before, and there is a secondary use risk, and an alarm prompt is sent to embody an operator.
In one embodiment, after the host 4 and the endoscope 1 are in electrical communication, the step of obtaining the length of the electrical communication between the endoscope 1 and the connection wire 3 includes:
acquiring the type of the host 4 when the endoscope 1 is in an electrical communication state with the host 4;
When the type of the host computer 4 is the host computer 4 for testing, the timing of the electric communication state between the endoscope 1 and the host computer 4 for testing is stopped;
When failure information of the endoscope 1 is acquired, a failure code corresponding to the failure information is displayed.
Here, the controller may perform signal interaction with the host computer 4 to determine the type of the host computer 4, and the endoscope 1 is not required to extend into the human body when the endoscope 1 is tested, and thus is not determined to be used. Based on the embodiment, the electrical communication in the test process does not affect the recording of the electrical communication duration, so the reference duration may be set to 0. The scheme effectively avoids the misjudgment of the secondary use condition of the endoscope 1 caused by the interference of the test to the electric communication time length.
Further, in the solution for obtaining the electrical connection duration in step S51, the following embodiment may be adopted, and after the host computer 4 is electrically connected to the endoscope 1, the step of obtaining the electrical connection duration between the endoscope 1 and the connection wire 3 includes:
When the endoscope 1 is in an electric communication state with the host 4, acquiring identity information of the endoscope 1;
The method comprises the steps of searching the identity information of the endoscope 1 in an identity information library of the endoscope 1 to determine the electric communication time between the endoscope 1 and the connecting wire 3, wherein the identity information library is used for recording the identity information of the endoscope 1 which has a connection relation with the connecting wire 3 and the electric communication time of the endoscope 1 corresponding to the identity information, and the electric communication time of the endoscope 1 is the accumulated time of the electric communication state between the endoscope 1 and the connecting wire 3;
when the identity information of the endoscope 1 is not found, the endoscope 1 is clocked from 0, and the identity information of the endoscope 1 is stored in an identity information library.
In this embodiment, if the endoscope 1 is used, the electrical connection time recorded in the identity information library will be represented by a relatively long time. If the endoscope 1 is simply subjected to an energization test, the recorded electric communication time period is relatively short. Medical staff can distinguish.
Here, the identification information may be embodied by a serial number, a bar code, or a two-dimensional code identified on the endoscope 1. After the first communication interface 31 is electrically connected with the handle interface, the electric connection duration recording module and the main control circuit in the endoscope 1 can perform handshake communication, so that identity information of the endoscope 1 is obtained. The identity information base of the endoscope 1 may be stored in a server or in a network cloud. The electrical communication duration recording module can access the identity information library directly or through the host computer 4, and search the identity information of the endoscope 1 and the corresponding previously recorded electrical communication duration, so that the use history of the endoscope 1 can be known, and a medical staff can determine whether the endoscope 1 has been used or not. The present embodiment further improves the standardization of the use management of the endoscope 1, and can effectively prevent the endoscope 1 from being used secondarily.
The present embodiment can realize management of the history of use of the endoscope 1, preventing the endoscope 1 that has been used from being used again, and thus the present embodiment improves the use safety and management standardization of the endoscope 1.
In step S52, in the state where the main unit 4 and the endoscope 1 are in electrical communication, the electrical communication duration between the endoscope 1 and the connection wire 3 is updated based on the electrical communication duration.
Here, the electrical communication time period may be regarded as the used time period of the endoscope 1. In some embodiments, an ambient light sensor may be further disposed on the insertion portion 11 of the endoscope 1, the ambient light sensor being used to detect an environment in which the endoscope 1 is located, and the electrical communication duration recording module being electrically connected to the ambient light sensor to start timing when the ambient light sensor detects that the endoscope 1 is entering the subject. And, the timing process may be displayed on the display screen 322.
Specifically, the method for updating the electrical communication duration between the endoscope 1 and the connecting wire 3 based on the electrical communication duration in the state that the host computer 4 and the endoscope 1 are in electrical communication comprises the steps of:
when the host computer 4 and the endoscope 1 are in an electric communication state, the proportion of red light in the light signals collected by the ambient light sensor;
if the ambient light sensor detects that the proportion of red light is greater than the preset threshold, the timing of the host 4 and the endoscope 1 being in electrical communication is started.
The ambient light sensor can sense the current environment where the bending part 13 of the endoscope 1 is located, and illustratively, when the red light proportion in the environment is detected to be increased to about 50%, the bending part 13 is judged to have entered the human body, and at the moment, the ambient light sensor sends a timing signal to the electrical communication duration recording module, starts to start timing, and displays the timing duration on the display module 32 in real time.
Because the endoscope 1 is connected to the host computer 4 through the connecting wire 3, medical staff needs to perform preoperative preparation, and does not immediately start operation, through the scheme of the embodiment, the electric communication duration recording module starts timing after entering a human body, so that the recorded electric communication duration truly reflects the actual operation duration of the endoscope 1 in the human body, the use duration of the endoscope 1 is convenient to manage, and the accuracy of judging whether the endoscope 1 is used secondarily is improved.
In one embodiment, S53, before the step of cutting off the communication connection between the endoscope 1 and the host computer 4 when the electrical communication time period reaches the preset limit use time period, the method further includes:
And when the electric communication duration reaches the preset normal use duration, sending out first alarm information, wherein the normal use duration is smaller than the limit use duration.
Here, the limit use period and the regular use period may be set individually by a manufacturer or a hospital according to the type of the endoscope 1. The normal use time length can be set to 70% -95% of the limit use time length.
The first alarm mode may be an optical alarm mode, for example, a warning light module provided on the connection line 3 or changing the backlight of the display screen 322 to a specific color, for example, orange. When the electrical communication duration recording module reaches the normal use duration, the alarm module starts a first alarm mode to remind an operator that the residual use duration of the endoscope 1 is not much.
Here, the communication connection between the endoscope 1 and the host computer 4 may be cut off by the controller in the connection line 3, or the controller may send an interrupt communication command to the host computer 4, and the host computer 4 stops receiving the signal sent by the endoscope 1 to force the endoscope 1 to be out of use.
Further, in an embodiment, step S53, when the electrical connection time period reaches the preset limit use time period, cuts off the communication connection between the endoscope 1 and the host 4, including:
when the electric communication duration reaches the limit use duration, sending out second alarm information, wherein the warning property of the second alarm information is higher than that of the first alarm information;
starting a countdown on the display module 32 and counting a first time period;
When the countdown is completed, the communication connection between the endoscope 1 and the host computer 4 is cut off.
The second alarm mode may be an audible alarm mode, where the alarm module includes a speaker assembly to send out a voice alert. Or change the backlight illumination mode of the display module 32 to a red flash mode to alert the operator that the remaining use time of the endoscope 1 is spent in a more warning manner.
In order to secure the safety of the operation, the first time period may be set to a time period required to withdraw the endoscope 1 from the human body. Thus, the endoscope 1 can be ensured to safely and smoothly exit the human body, and the phenomenon that the endoscope 1 scratches the inner cavity of the human body in the process of exiting the human body due to the fact that the endoscope 1 stops working is avoided.
Further, if a special situation is encountered during the operation, the operation time needs to be prolonged, so in order to ensure the smooth operation, in an embodiment, step S53, when the electrical connection time reaches the preset limit use time, the step of cutting off the communication connection between the endoscope 1 and the host 4 further includes:
Before the preset limit use time length is not reached, if a delay common instruction is received, the limit use time length is prolonged according to the delay common instruction, and the related information of the new limit use time length is updated on the display module 32;
when the electrical communication time period reaches the new limit use time period, the communication connection between the endoscope 1 and the host computer 4 is cut off.
Here, it should be noted that, the endoscope 1 may also receive a time delay general command, and the controller learns the time extension information through signal interaction with the endoscope 1, so as to control the display screen 322 to update the display limit use duration, or update the remaining use duration for display. The time extension instruction may also be received by the host 4, and the time extension information may be transmitted to the controller through signal interaction.
Here, the operator has the authority to issue a time-lapse normal instruction, which is normally only once, so as to ensure that the use time of the endoscope 1 is strictly controlled and secondary use is prevented.
Specifically, the operator can directly send out the instruction by the man-machine interaction component on the host computer 4, or unlock the delay claim after inputting a specific password, or a slot for inserting an IC card is provided on the host computer 4, the endoscope 1 or the casing 321 of the display module 32, and the operator unlocks the delay claim by inserting the IC card, and further sends out a delay general instruction. The delay common instruction comprises a specific time length which needs to be prolonged.
For example, the preset limit use time of the endoscope 1 is 120 minutes, when the record time of the electric communication time recording module reaches 100 minutes, the operator issues a delay normal instruction, and the display module 32 updates the display limit use time to 150 minutes or displays the remaining use time to 50 minutes after 30 minutes delay.
Further, if the operation is too complicated and still cannot be completed after the limit use time is prolonged, in order to ensure that the endoscope 1 can continue to support normal operation, in an embodiment, before the preset limit use time is not reached, if the delay normal instruction is received, after the step of prolonging the limit use time according to the delay normal instruction, the method further includes:
and before the new limit use time length is not reached, if a delay special instruction is received, the current limit use time length is lengthened again according to the delay special instruction, wherein the delay special instruction is sent by the authorization key.
It should be noted that, herein, the "current limit use duration" is the limit use duration after the delay of the normal instruction.
The form of the authorization key may be varied, for example, an authorization shield provided by the manufacturer, which is typically administered by a higher level operator. After the above-mentioned normal delay claims have been used, the operator can also utilize the authorization key to extend the duration of the limit use one or more times, if necessary, to meet the surgical requirements.
The embodiment of the application adjusts the limit use time of the endoscope 1 by delaying the common instruction and delaying the special instruction, so that the endoscope 1 can support the smooth completion of the operation, and simultaneously, the application reduces the limit use time of the endoscope 1 by setting the issuing authority of the delaying the common instruction and delaying the special instruction, thereby being used for the next operation because of the excessive extension of misoperation or maliciousness, thereby effectively reducing the possibility of the secondary use of the endoscope 1.
In connection with the above embodiments, if the limit use period is excessively prolonged, the endoscope 1 has a remaining use period after the operation is ended, so in order to prevent the possibility that the endoscope 1 may be used next time, the method further includes, in one embodiment:
after the endoscope 1 leaves the human body, acquiring the time length extension data sent by the authorization shield;
If the time length extension data is greater than the preset time extension range, it is judged that the time extension is abnormal, thereby marking that the endoscope 1 has been used.
Therefore, after the endoscope 1 leaves the human body, the controller or the host 4 can acquire the time length extension data sent by the authorization shield, and if the time length extension data is larger than the preset time extension range, the time extension is judged to be abnormal, so that the endoscope 1 is marked as used in the identity database of the endoscope 1. Therefore, if the endoscope 1 is electrically connected to the connection wire 3 again, the history of the use can be recognized by the connection wire 3, and the secondary use can be prevented. The preset time extension range is determined by a manufacturer after finishing statistics according to time extension data of all the authorized shields, so that the time delay duration is ensured to be matched with the time delay duration under normal conditions.

Referring to fig. 4 to 6, fig. 4 is a schematic structural diagram of a connecting wire 3 according to an embodiment of the application. Fig. 5 is another view of the connecting wire 3 of fig. 4. Fig. 6 is a partial schematic view of the structure of fig. 4. Specifically, in one embodiment, the connection line 3 includes a first communication interface 31, a cable portion 33, an electrical communication duration recording module, and a controller. The first communication interface 31 is used for being inserted into the handle 12 of the endoscope 1 to receive and send various communication signals with the endoscope 1, one end of the cable part 33 is connected to the first communication interface 31, the other end of the cable part is connected to the host 4, the electric communication duration recording module is electrically connected with the first communication interface 31 to record and update the electric communication duration between the endoscope 1 and the first communication interface 31, and when the electric communication duration reaches the preset limit use duration, the controller cuts off the communication connection between the endoscope 1 and the host 4 and marks that the endoscope 1 has been used.
In this embodiment, the used time of the endoscope 1 is determined by recording the electric communication time of the endoscope 1, and when the electric communication time reaches the preset limit use time, the communication connection between the endoscope 1 and the host 4 is cut off to prevent the endoscope 1 from being used continuously, thereby achieving the purpose of preventing secondary use.
And can further mark that the endoscope 1 has been used while the electrically connected time period reaches a preset limit use time period, so that when the endoscope 1 is reused after being disconnected from the host computer 4, the connecting wire 3 can recognize the mark, thereby cutting off the communication between the endoscope 1 and the host computer 4, and achieving the purpose of preventing secondary use.
The handle 12 is provided with a handle interface, and the first communication interface 31 of the connecting wire 3 and the handle interface can be detachably connected in a plug-in mode, so that the connecting wire 3 can be repeatedly used by replacing the endoscope 1, and the use cost of the endoscope 1 is reduced.
Illustratively, the cable portion 33 includes a plurality of signal transmission lines, and a protective sleeve surrounding the signal transmission lines. The plurality of signal transmission lines are used for transmitting different communication signals, and of course, in some cases, one signal transmission line may be multiplexed to transmit two or more communication signals, which is not limited herein.
The communication interface of the connection line 3 and the host 4 is referred to herein as a second communication interface. After the first communication interface 31 is plugged into the handle interface on the handle 12 and the second communication interface is electrically connected to the host 4, the cable portion 33 can transmit the communication signal between the endoscope 1 and the host 4. The communication signals herein include, but are not limited to, power supply signals, image compression information, endoscope 1 operating voltage signals, operating current signals, operating timing control signals, and the like.
In the related art, the operator holds the handle 12 of the endoscope to perform the operation, and the host 4 is far from the operator, typically more than 1 meter away, which requires that the operator should enlarge the video information displayed by the display device as much as possible during the operation. The other working state information of the endoscope 1 device is displayed on the display device relatively smaller, so that the operator is likely to be unable to acquire the working state of the endoscope 1 in real time, and the smooth operation is affected.
Therefore, in order to enable the operator to better know the working state information of the endoscope 1 during the operation, in one embodiment, the connecting wire 3 further includes a display module 32, the display module 32 includes a housing 321 and a display screen 322, the display screen 322 is disposed on the housing 321, the first communication interface 31 is disposed on one end of the housing 321, the cable portion 33 is penetrated from the other end of the housing 321 and connected to the host computer 4, and the display screen 322 is electrically connected to the electrical communication duration recording module to display the electrical communication duration recorded by the electrical communication duration recording module or display the remaining use duration of the endoscope 1. Of course, the display screen 322 may also be electrically connected to a plurality of signal transmission lines in the cable portion 33, so as to acquire a real-time operation state signal of the endoscope 1 and display corresponding operation state information.
In this embodiment, when the connection wire 3 is electrically connected between the host computer 4 and the endoscope 1, the display screen 322 instantly displays the electrical communication time between the endoscope 1 and the communication interface, so that the operator can quickly learn the historical use condition of the endoscope 1, and the secondary use of the endoscope 1 can be effectively avoided.
In this embodiment, the display content of the display screen 322 may also include various operating parameter information of the endoscope 1. Through the design of display screen 322 on connecting wire 3 for endoscope 1's operating condition information need not to show on host computer 4 screen, perhaps shows with less occupation interval, thereby makes host computer 4 screen can further enlarge the image picture, the operation of convenient to use person more accurate.
In addition, the position design of the display screen 322 on the connecting wire 3 accords with the ergonomic design, so that when an operator performs an operation by holding the handle 12 of the endoscope 1, the display screen 322 is positioned at the tiger mouth of the palm, and the display surface is positioned at the optimal position of the sight line, thereby being convenient for a user to intuitively see the information on the display screen 322.
In a specific embodiment, the housing 321 is cylindrical, and the display screen 322 is disposed vertically in the radial direction of the connector. The display screen 322 is vertically disposed in the axial direction of the housing 321. The design ensures that the information displayed on the display is in the optimal visual angle range when a user operates the handle 12 of the endoscope 1, thereby improving the convenience of information checking.
And the cross-sectional diameter length of the housing 321 may be 1cm to 3cm, and the radial length of the housing 321 along itself may be 0.5cm to 3cm. Which is adapted to the size of the palm of the human hand to facilitate the user's grip on the housing 321.
In a specific embodiment, the cross section of the casing 321 may be elliptical, which is opposite to the circular design, so that the contact area with the hand can be increased during the plugging operation, and the plugging operation is convenient for the user. The major axis of the ellipse may be 1cm to 3cm, and the length of the housing 321 in its own radial direction is 0.5cm to 3cm.
Referring to fig. 7, fig. 7 is a schematic view of a portion of the structure of the housing 321 in fig. 4. In an embodiment, anti-skidding patterns 3211 may be further disposed on the outer surface of the casing 321, so that when the first communication interface 31 is plugged, friction force between the first communication interface and the palm can be increased, and quick and effective plugging can be achieved.
In a specific embodiment, the housing 321 has a handle interface thereon that is removably coupled to the display. The detachable connection mode can be in buckle connection or plug connection. The separation of the display and the casing 321 is realized in this embodiment, so that the display screen 322 and the casing 321 can be provided as separate products, and the cost of the updated products of hospitals is reduced.
In the related art, the endoscope 1 company selects to design a dedicated interface by itself to prevent the mixed use of the respective devices, thereby forming a market barrier. In an embodiment of the present application, the first communication interface 31 is a universal interface, and may specifically include one or more of an HDMI interface, a USB interface, and a Type-C interface. It should be understood that the handle interface on the corresponding handle 12 in this embodiment is of the same type as the first communication interface 31. The embodiment reduces the workload of designing a new special port by updating the communication protocol when the connecting wire 3 is updated, and can be used in other endoscope 1 products in a general way, thereby having wide usability.
As before, the connecting wire 3 further comprises an electrical communication duration recording module. Illustratively, when the endoscope 1 is required to be used, after the first communication interface 31 is plugged into the handle interface on the handle 12 and the second communication interface is electrically connected to the host 4, the host 4 may send an electrical signal to the endoscope 1 through the cable portion 33, where the electrical signal may be a power signal for power supply or a control signal. During the use of the endoscope 1, the first communication interface 31 is in plug connection with the handle interface on the handle 12, and the electric signal is continuously transmitted, so that the electric communication duration is detected and recorded by the electric communication duration recording module. When the operation of the endoscope 1 is completed, after the first communication interface 31 is disconnected from the handle interface, the electrical signal is interrupted, and the electrical communication duration recording module can detect the interruption of the electrical signal, so that the recording of the electrical communication duration is stopped.
In a specific embodiment, the electrical communication duration recording module may include a sampling circuit and a timing circuit, wherein an input end of the sampling circuit is connected to the first communication interface 31, and an output end of the sampling circuit is connected to the timing circuit. When the first communication interface 31 is electrically connected with the handle interface on the handle 12, the input end of the sampling circuit can sample the voltage, and the timing circuit is used for recording the holding time length of the sampled voltage, and the holding time length is used as the electrical communication time length between the handle interface and the first communication interface 31. It is apparent that during the operation, the electrical communication duration recording module will continuously record the electrical communication duration, and stop recording after the first communication interface 31 is separated from the handle interface on the handle 12 after the operation is completed.
Here, the electrical communication time period may be regarded as the used time period of the endoscope 1. In some embodiments, an ambient light sensor may be further disposed on the insertion portion 11 of the endoscope 1, the ambient light sensor being used to detect an environment in which the endoscope 1 is located, and the electrical communication duration recording module being electrically connected to the ambient light sensor to start timing when the ambient light sensor detects that the endoscope 1 is entering the subject. And, the timing process may be displayed on a display.
The ambient light sensor can sense the current environment where the bending part 13 of the endoscope 1 is located, and illustratively, when the red light proportion in the environment is detected to be increased to about 50%, the bending part 13 is judged to have entered a human body, and at the moment, the ambient light sensor sends a timing signal to the electrical communication duration recording module to start timing, and the timing duration is displayed on the display.
Because the endoscope 1 is connected to the host computer 4 through the connecting wire 3, medical staff needs to perform preoperative preparation and does not immediately start operation, by the scheme of the embodiment, the electric communication duration recording module starts timing after entering a human body, so that the recorded electric communication duration truly reflects the actual operation duration of the endoscope 1 in the human body, thereby being beneficial to improving and actually recording the electric communication duration of the endoscope 1 in a use state, controlling the operation progress by an operator, and ensuring the life safety of a patient.
In an embodiment, the connecting wire 3 further comprises an alarm module, wherein the alarm module is used for sending out first alarm information when the electrical communication duration reaches a preset normal use duration, and the normal use duration is smaller than the limit use duration. Here, the limit use period and the regular use period may be set individually by a manufacturer or a hospital according to the type of the endoscope 1. The normal use time length can be set to 70% -95% of the limit use time length.
The first alarm mode may be an optical alarm mode, for example, a warning light module provided on the connection line 3 or changing the backlight of the display screen 322 to a specific color, for example, orange. When the electrical communication duration recording module reaches the normal use duration, the alarm module starts a first alarm mode to remind an operator that the residual use duration of the endoscope 1 is not much.
In one embodiment, the alarm module is further configured to send out second alarm information when the electrical connection duration reaches the limit of use duration, where the second alarm information has higher warning performance than the first alarm information. And when the countdown is completed, the communication connection between the endoscope 1 and the host computer 4 is cut off.
The second alarm mode may be an audible alarm mode, where the alarm module includes a speaker assembly to send out a voice alert. Or the backlight lighting mode of the display is changed to be a red flashing mode, so that the operator is reminded of the residual using time of the endoscope 1 in a more alarming manner.
In order to secure the safety of the operation, the first time period may be set to a time period required to withdraw the endoscope 1 from the human body. Thus, the endoscope 1 can be ensured to safely and smoothly exit the human body, and the phenomenon that the endoscope 1 scratches the inner cavity of the human body in the process of exiting the human body due to the fact that the endoscope 1 stops working is avoided.
Further, if a special condition is encountered during the operation, the operation time needs to be prolonged, so in order to ensure smooth operation, in an embodiment, the controller is further configured to receive a delay normal instruction. The display screen 322 is also used to update the display limit use period or update the remaining use period of the display endoscope 1 in accordance with the time delay general instruction received by the controller.
Here, the endoscope 1 may receive a time delay general command, and the controller may learn the time extension information through signal interaction with the endoscope 1, so as to control the display screen 322 to update the display limit use time period or the remaining use time period available for use. The time extension instruction may also be received by the host 4, and the time extension information may be transmitted to the controller through signal interaction.
Here, the operator has the authority to issue a time-lapse normal instruction, which is normally only once, so as to ensure that the use time of the endoscope 1 is strictly controlled and secondary use is prevented.
Specifically, the operator can directly send out the instruction by the man-machine interaction component on the host computer 4, or unlock the delay claim after inputting a specific password, or a slot for inserting an IC card is provided on the host computer 4, the endoscope 1 or the casing 321 of the display module 32, and the operator unlocks the delay claim by inserting the IC card, and further sends out a delay general instruction. The delay common instruction comprises a specific time length which needs to be prolonged.
For example, the preset limit use duration of the endoscope 1 is 120 minutes, when the record duration of the electric communication duration record module reaches 100 minutes, the operator sends out a delay common instruction, and the display updates and displays the limit use duration of 150 minutes or displays the residual use duration of 50 minutes after 30 minutes delay.
Further, if the operation is too complicated, the operation cannot be completed after the time of the limit use is prolonged, and in order to ensure that the endoscope 1 can continue to support normal operation, in an embodiment, the controller is further configured to directly or indirectly receive a delay general instruction, and when receiving a delay special instruction, the controller controls to re-extend the current time of the limit use according to the delay special instruction, where the delay special instruction is issued by the authorization key.
It should be noted that, herein, the "current limit use duration" is the limit use duration after the delay of the normal instruction.
The form of the authorization key may be varied, for example, an authorization shield provided by the manufacturer, which is typically administered by a higher level operator. After the above-mentioned normal delay terms have been used, the doctor can also use the authorization key to extend the limit use time one or more times, if necessary.
If the limit use time period is excessively prolonged, the endoscope 1 still has a remaining use time period after the operation is finished, so that in order to prevent the endoscope 1 from being possibly used next time, in one embodiment, after the endoscope 1 leaves the human body, the controller or the host 4 can acquire the time period prolonged data sent by the authorized shield, if the time period prolonged data is greater than the preset time prolonged range, the time period prolonged abnormality is judged, and the identity database of the endoscope 1 is marked that the endoscope 1 has been used. Therefore, if the endoscope 1 is electrically connected to the connection wire 3 again, the history of the use can be recognized by the connection wire 3, and the secondary use can be prevented.
The preset time extension range is determined by a manufacturer after finishing statistics according to time extension data of all the authorized shields, so that the time delay duration is ensured to be matched with the time delay duration under normal conditions.
The application further provides a control method of a medical observation system, the medical observation system comprises an endoscope 1, a host 4 and a connecting wire 3 electrically connecting the endoscope 1 and the host 4, wherein the structural embodiment of the endoscope 1, the host 4 and the connecting wire 3 is referred to the above embodiment, and the description is omitted herein.
While the present disclosure has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration rather than of limitation. As the present disclosure may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
