Referring to fig. 1, an embodiment of the present invention provides a surgical instrument, including: the scalpel comprises a protective cover 1, a scalpel head 2, a power output device 3, a rotating device 4, an adsorption device 5, a feedback device 6, an alarm device 7 and a shell 8; wherein,
the rotating device, the adsorption device and the alarm device are all positioned in the shell;
the rotating device is respectively connected with the power output device, the scalpel head and the adsorption device;
the feedback device is arranged on the scalpel head;
the protective cover is of a tubular structure with one closed end, an opening is formed in the side wall close to the closed end, and the scalpel head and the feedback device are both located in the protective cover;
the alarm device is arranged on the inner wall of the shell;
the feedback device is used for acquiring operation and maintenance information of the scalpel bit and feeding back the operation and maintenance information to the power output device;
the power output device corresponds to at least one gear and is used for outputting the power of the corresponding gear according to the operation and maintenance information;
the rotating device is used for performing rotating motion at a corresponding speed and reciprocating motion at a corresponding speed according to the power output by the power output device;
the scalpel head is provided with a cutting edge at one end far away from the rotating device, is driven by the rotating device to rotate and reciprocate, and cuts off abnormal tissues entering the opening by the cutting edge during the rotation and reciprocation; when the scalpel bit reciprocates, the distance between the cutting edge and the closed end of the protective cover is greater than the distance between the opening and the closed end of the protective cover;
the adsorption device is used for sucking out the cut substances;
the warning device is used for monitoring touch information of the rotating device, determining whether the target distance between the scalpel head and the closed end of the protective cover is not greater than an absolute limit value or not according to the touch information, generating warning information when the target distance is not greater than the absolute limit value, and sending the warning information to an external terminal.
According to the embodiment, the power output device outputs the power of the corresponding gear according to the operation and maintenance information fed back by the feedback device so as to drive the rotating device to rotate and reciprocate, the scalpel head is driven by the rotating device to rotate and reciprocate, and in the moving process, abnormal tissues entering an opening of the protective cover can be cut off, and the absorption device is used for sucking out cut substances; in order to ensure the safety of the surgical process, the warning device is utilized to determine the target distance between the scalpel head and the closed end of the protective cover in the operation process, and warning information is generated to give a warning when the target distance is not more than an absolute limit value so as to ensure the safety of the surgical process; because the rotating motion of the scalpel bit is related to the reciprocating motion speed according to the power of the power output device, when the reciprocating motion speed reaches a certain value, abnormal tissues entering the opening of the protective cover can be quickly cut off without residue, and thus the healing effect can be improved.
In an embodiment of the present invention, the operation and maintenance information fed back to the power output device by the feedback device may include: the type of the scalpel head, the friction correction factor of the scalpel head, the current rotational speed of the scalpel head, and the current torque of the scalpel head.
Types of scalpel heads may include: at least one of a model, a material, and a size. When the types of the scalpel heads are different, gears corresponding to the power output by the power output device can also be different. Wherein, the power of different gears corresponds to different rotational speeds and moments.
Different types of scalpel heads may correspond to different coefficients of friction correction. When the friction force correction coefficient of the scalpel bit is different, the power output device can correct the determined power of the corresponding gear according to the type of the scalpel bit, so that the power output after correction is guaranteed to be more suitable for the scalpel bit.
The feedback device can also monitor and feed back the current rotating speed and the current torque of the scalpel head during working, so that the power output device can determine the difference degree between the actual power and the output power of the scalpel head during working, and exception handling can be performed when the difference is obvious.
For the type of the scalpel head and/or the friction correction factor included in the operation and maintenance information, in an embodiment of the present invention, the feedback device may obtain and feed back the type of the scalpel head and/or the friction correction factor as follows:
referring to fig. 2, the feedback device 6 may include: a memory chip 61 and a first communication means 62.
Since the feedback device is provided on the scalpel head, the type of the scalpel head and/or the friction correction factor can be known when the scalpel head is produced, and the type of the scalpel head and/or the friction correction factor is stored in the memory chip, and the first communication device transmits the type of the scalpel head and/or the friction correction factor stored in the memory chip to the power output device.
For the current rotation speed of the scalpel head and/or the current torque of the scalpel head included in the operation and maintenance information, in an embodiment of the present invention, the feedback device may obtain and feed back the current rotation speed and/or the current torque of the scalpel head by:
referring to fig. 3, the feedback device 6 includes: a detector 63 and a second communication means 64.
The detector detects the current rotating speed of the scalpel head and/or the current torque of the scalpel head, and the detected current rotating speed of the scalpel head and/or the current torque of the scalpel head are sent to the second communication device and forwarded to the power output device by the second communication device.
The mode of detecting the current rotating speed of the scalpel head by the detector can be realized by the following modes: the light emitter is arranged on the inner wall of the protective cover, and when the scalpel bit rotates, the detector can detect light emitted by the light emitter in one part of time and cannot detect light emitted by the light emitter in the other part of time. Thus, the detector can determine the current rotational speed of the scalpel head from each two adjacent time periods in which light is detected.
The mode of detecting the current moment of the scalpel head by the detector can be realized by the following modes: the friction force of the scalpel head is detected by the detector, when the scalpel head does not cut abnormal tissues, the friction force of the scalpel head can be determined to be 0, and when the scalpel head cuts the abnormal tissues, a certain friction force exists between the scalpel head and the abnormal tissues, so that the current moment of the scalpel head is determined by the detector according to the time period when the scalpel head is detected to have the friction force every two adjacent times.
In an embodiment of the present invention, the power output device may be a motor capable of adjusting an output power value, and at least one gear may be set on the power output device, each gear outputting different power correspondingly, for example, 10 gears are set, and each gear may drive the rotating device to rotate at a rotation speed of 1000r/min, 2000r/min, 3000r/min, …, 10000r/min when outputting corresponding power. The power output device can also be provided with a rotating speed input interface, the power output device determines the required rotating speed according to the operation and maintenance information fed back by the feedback device, and inputs the rotating speed through the rotating speed input interface so as to realize the gear setting corresponding to the rotating speed, and the power output device can output the power corresponding to the gear.
Since the power output by the power output device needs to drive the rotating device to rotate, the output power can be a rotating power.
In an embodiment of the present invention, in order to realize the rotation and the reciprocation of the rotating device 4, referring to fig. 4, the rotating device may include: the device comprises a driving shaft 41, a transmission shaft 42, a first gear 43, a second gear 44, a bidirectional screw 45, a sliding block 46 and a limiting device 47; wherein,
the driving shaft is connected with the power output device and is used for performing rotary motion at a corresponding speed around the axis of the driving shaft under the driving of the power output by the power output device; for example, the power output by the power output device corresponds to the rotating speed of 6000r/min, and then the driving shaft can rotate at the rotating speed of 6000 r/min.
The first gear is sleeved on the driving shaft and is fixedly connected with the driving shaft;
the second gear is sleeved on the transmission shaft and is fixedly connected with the transmission shaft;
the first gear is meshed with the second gear;
when the driving shaft rotates, the first gear is driven to rotate in the same direction as the driving shaft; the first gear performs rotary motion in the direction opposite to the driving shaft under the action of the second gear; the transmission shaft is driven by the first gear to rotate in the direction opposite to the driving shaft.
If the rotating speeds of the driving shaft and the transmission shaft are required to be the same, the first gear and the second gear can be set to have the same diameter. If the rotating speed of the driving shaft is required to be different from that of the transmission shaft, the first gear and the second gear can be set to have unequal diameters. Therefore, in order to reduce the loss of the power output device, the power output device can output power corresponding to the rotating speed of 2000r/min, the rotating speed of the driving shaft during the rotating motion is 2000r/min, and if the rotating speed of the transmission shaft is required to be 6000r/min, the diameter of the first gear needs to be three times that of the second gear.
The bidirectional screw rod is sleeved on the driving shaft and is fixedly connected with the driving shaft;
the slide block is respectively connected with the bidirectional screw rod and the limiting device;
the limiting device is fixed at one end of the transmission shaft, which is far away from the scalpel head;
when the driving shaft rotates, the bidirectional screw rod is driven to rotate in the same direction as the driving shaft; when the bidirectional screw rod rotates, the sliding block reciprocates along the axis direction of the driving shaft, and the sliding block and the limiting device generate an interaction force to drive the transmission shaft to reciprocate along the axis of the transmission shaft.
In the operation process, if the scalpel bit touches the safety cover blind end when carrying out reciprocating motion, not only can cause the influence to the sharpness of scalpel bit, still can lead to the scalpel bit to wear out the safety cover blind end, cause the mistake to cut to patient's normal tissue. Therefore, in an embodiment of the present invention, a movement track of the rotating device during the reciprocating motion may be set according to a distance between the scalpel head and the closed end of the protective cover, where the movement track is used to ensure that when the rotating device drives the scalpel head to perform the reciprocating motion, and the scalpel head moves towards the closed end of the protective cover to the bottommost end, a certain safety distance is still left between the scalpel head and the closed end of the protective cover.
In case of a failure of the rotating device, the target distance between the scalpel head and the closed end of the protective cover may be smaller than the safety distance, and therefore, in order to further ensure the safety during the operation, in an embodiment of the present invention, an absolute value may be set in the warning device, where the absolute value is not larger than the safety distance. For example, the threshold value is 1 cm.
In one embodiment of the present invention, the position of the alarm device disposed on the inner wall of the housing may include the following two ways:
mode 1: under the condition that the target distance is not less than the threshold value, the rotating device touches the warning device once when executing reciprocating motion each time.
Mode 2: and under the condition that the target distance is not less than the absolute limit value, the rotating device does not touch the alarm device every time the rotating device executes reciprocating motion.
The following describes the alarm device in detail with respect to the above-described modes 1 and 2, respectively.
In view of the above aspect 1:
in the mode 1, the alarm of the alarm device can be realized by a current monitoring mode.
In an embodiment of the present invention, referring to fig. 5, the warning device 7 includes: a current control device 71, a microprocessor 72, an alarm circuit 73 and a third communication device 74;
the current control device and the microprocessor are respectively connected with the alarm circuit;
the microprocessor is connected with the third communication device;
the current control device is used for being in contact with the rotating device when the rotating device realizes reciprocating motion; determining the running distance of the rotating device in the touch process according to the touch information of the rotating device; controlling the alarm circuit to generate a current value in a set proportion to the running distance; in addition, according to the above fig. 4, the current control device can monitor the information of the contact with the slider in the rotating device.
The microprocessor is used for configuring a current threshold value and monitoring the current value of the alarm circuit; when the current value of the alarm circuit is monitored to reach the current threshold value, determining that the target distance between the scalpel head and the closed end of the protective cover is not larger than the limit value, generating alarm information, and sending the generated alarm information to the third communication device;
and the third communication device is used for sending the received alarm information to the terminal.
In the mode 1, the rotating device may be always in a contact state with the current control device when reciprocating; the rotating device can also be arranged to not touch the current control device when the distance between the scalpel head and the closed end of the protective cover is the largest during reciprocating motion of the rotating device, and the rotating device and the current control device start to touch when the distance between the scalpel head and the closed end of the protective cover is gradually reduced.
