For cutting instruments such as planers, grinding heads and bone drills that rotate along their own axes to cut human tissue during operation, in addition to meeting the size requirements of the drawings, the cutting force of the surgical instruments must also meet the standards. For cutting instruments such as blades that cut human tissue along a straight line during operation, and puncture instruments such as puncture needles that puncture human tissue along a straight line during operation, the sharpness of the surgical instruments must also be guaranteed to meet the standards.

[0047] Refer to the following Figures 1 to 5 The surgical instrument detection device provided by the present invention is described.

[0048] The surgical instrument detection device is designed to be compatible with the detection requirements of various instruments, namely, the detection requirements of cutting instruments, cutting instruments and puncture instruments, so as to reduce the manufacturer's equipment procurement costs and thus reduce the manufacturer's production costs. Please refer to the following embodiments for the exemplary structure of the surgical instrument detection device.

[0049] Embodiment 1

[0050] Reference Figure 1 The surgical instrument detection device comprises a base 1, a driving mechanism 2, a positioning mechanism 3 and a detection mechanism. The base 1 is provided with a clamping mechanism 4 for clamping a sample. The positioning mechanism 3 is provided on the driving mechanism 2. The positioning mechanism 3 can clamp the surgical instrument. The driving mechanism 2 can drive the positioning mechanism 3 to move in a preset direction so that the surgical instrument can abut against the sample on the clamping mechanism 4. The detection mechanism is configured to detect the pressure of the surgical instrument acting on the sample.

[0051] Specifically, the base 1 of this embodiment is arranged horizontally, the driving mechanism 2 is arranged on the base 1, and the preset direction of this embodiment is the vertical direction. In some other embodiments, the base 1 can also be tilted to a certain extent. Figure 2 The clamping mechanism 4 includes a clamping seat 41, a first pressing block 42 and a second pressing block 43. The clamping seat 41 is connected to the base 1. The first pressing block 42 and the second pressing block 43 are arranged on the clamping seat 41 at intervals, and the distance between the first pressing block 42 and the second pressing block 43 is adjustable.

[0052] When the sample needs to be positioned, the sample is first placed on the clamping seat 41 and located between the first pressing block 42 and the second pressing block 43. The sample is clamped and positioned by adjusting the distance between the first pressing block 42 and the second pressing block 43. It should be noted that the sample in this embodiment is an imitation bone for medical experiments, and the surgical instrument in this embodiment is a cutting instrument, specifically the grinding head 100 is used as an example for description. In some other embodiments, the sample may also be other materials that imitate human tissue.

[0053] In order to facilitate the adjustment of the position of the artificial bone, the clamping seat 41 in this embodiment is rotatably connected to the base 1, and the rotation axis of the clamping seat 41 is parallel to the preset direction, that is, the rotation axis of the clamping seat 41 is vertically arranged, and the position of the artificial bone can be adjusted by rotating the clamping seat 41.

[0054] Preferably, the first pressing block 42 is integrally formed on the clamping seat 41, and the second pressing block 43 is slidably connected to the clamping seat 41 and can be positioned at a preset position. In order to drive the second pressing block 43 to slide, a driving block 44 is also integrally formed on the clamping seat 41. The driving block 44 is located on the side of the second pressing block 43 away from the first pressing block 42. A screw 441 is passed through the driving block 44 and is threadedly connected to the screw 441. The end of the screw 441 is rotatably connected to the second pressing block 43. The staff can drive the second pressing block 43 to slide by rotating the screw 441, and limit the second pressing block 43 by the self-locking characteristic of the threaded connection, so that the second pressing block 43 can be positioned at a preset position.

[0055] In some other embodiments, the first pressing block 42 and the second pressing block 43 may be slidably connected to the clamping seat 41; and the sliding of the first pressing block 42 and the second pressing block 43 may be driven by a linear driving member such as a cylinder or an electric cylinder.

[0056] Reference Figure 1 The driving mechanism 2 includes a driving seat 21, a driving rod 22 and a support column 23. The support column 23 is connected to the base 1. The length direction of the support column 23 is parallel to the preset direction, that is, the support column 23 in this embodiment is vertically arranged. The driving seat 21 is arranged on the support column 23, and the driving rod 22 is connected to the driving seat 21. The driving rod 22 can move along the preset direction relative to the driving seat 21.

[0057] Specifically, the driving rod 22 in this embodiment is arranged along the vertical direction and is slidably arranged in the driving seat 21. The driving rod 22 and the driving seat 21 are driven by a gear rack, that is, a gear is rotatably arranged on the driving seat 21, and a rocker arm is connected to the gear. The driving rod 22 is provided with a rack meshing with the gear. By pressing the rocker arm downward, the driving rod 22 can be driven to move in the vertical direction. In addition, a return spring is also arranged between the driving rod 22 and the driving seat 21, so that the driving rod 22 is always subjected to an upward spring force, that is, when the rocker arm is not pressed downward, the driving rod 22 is always at a high position. In some other embodiments, the driving rod 22 can also be driven to move by other linear driving members such as a cylinder or an electric cylinder.

[0058] Furthermore, in order to facilitate the adjustment of the height of the drive seat 21, thereby adjusting the distance between the drive seat 21 and the base 1, a thread is processed on the outer wall of the support column 23, and the drive seat 21 is threadedly connected to the support column 23, so that the drive seat 21 can be rotated to move along the length direction of the support column 23, and the drive seat 21 is self-locked by the self-locking characteristics of the thread.

[0059] Since it is necessary to ensure that the driving rod 22 is stable in a predetermined position during the detection operation to prevent the driving rod 22 from moving abnormally and affecting the accuracy of the detection result, a limit assembly 5 is provided at one end of the support column 23 away from the base 1, and the limit assembly 5 is configured to limit the movement of the driving rod 22 in a direction away from the base 1. The limit assembly 5 specifically includes a limit seat 51 and a limit member 52. The limit seat 51 is threadedly connected to the support column 23 so that the limit seat 51 can move relative to the support column 23 along the length direction of the support column 23. A locking member 511 is threadedly connected to the limit seat 51. The locking member 511 in this embodiment is a locking screw, which is threadedly connected to the limit seat 51 and abuts against the support column 23, thereby preventing the limit seat 51 from moving abnormally.

[0060] Furthermore, the limiting member 52 is connected to the limiting seat 51, and the limiting member 52 abuts against the end of the driving rod 22 away from the base 1. The limiting member 52 in this embodiment is a screw, and the screw is vertically arranged and threadedly connected to the limiting member 52. The bottom end of the screw abuts against the top end of the driving rod 22, thereby achieving the limitation of the driving rod 22, and when the screw is rotated, it can move itself in the vertical direction (i.e., the preset direction) relative to the limiting seat 51 to tightly press the top end of the driving rod 22, thereby improving the limiting effect on the driving rod 22.

[0061] Reference Figure 3 The positioning mechanism 3 includes a positioning seat 31, a fixture seat 32 and a positioning fixture 33. The positioning seat 31 is connected to the bottom end of the driving rod 22. The fixture seat 32 is connected to the positioning seat 31 by rotating around a second axis. The second axis is perpendicular to a preset direction to adjust the angle between the fixture seat 32 and the imitation bone. Specifically, two ear plates 311 are arranged at intervals at the bottom of the positioning seat 31, and the positioning seat 31 is provided with an avoidance groove 312 corresponding to the gap between the two ear plates 311. The fixture seat 32 is arranged between the two ear plates 311 by rotating around the second axis. The second axis in this embodiment is arranged horizontally, so that the angle between the fixture seat 32 and the imitation bone can be adjusted by rotating the fixture seat 32 to meet the detection requirements of different angles. In addition, the fixture seat 32 can be pressed by a pressing block 3111 threadedly connected to the ear plate 311, so that the rotated fixture seat 32 is pressed and positioned.

[0062] Further, the positioning fixture 33 is connected to the fixture seat 32 by rotation around the first axis 400, the first axis 400 is perpendicular to the second axis, and the positioning fixture 33 can clamp the grinding head 100 so that the grinding head 100 can rotate relative to the fixture seat 32, and the grinding head 100 can extend out of the fixture seat 32 through the avoidance groove 312, and dock with the external driving member at the rear end of the grinding head 100. Specifically, the positioning fixture 33 in this embodiment is any fixture in the prior art that can clamp a columnar surgical instrument. The positioning fixture 33 in this embodiment takes a chuck as an example, the chuck is rotatably arranged through the fixture seat 32, and the grinding head 100 is coaxially installed with the chuck, that is, the first axis 400 is the axis of the grinding head 100 itself, and the specific form of the chuck is not limited.

[0063] In addition, in order to accurately control the detection angle of the grinding head 100, an angle mark 3112 is provided on the ear plate 311, and an indicator arrow 321 is provided on the clamp seat 32. Therefore, when the clamp seat 32 is rotated, the rotation angle of the clamp seat 32 can be accurately adjusted by observing the angle mark 3112 to meet the detection requirements of multiple angles.

[0064] The detection mechanism includes a pressure sensor 6. The pressure sensor 6 in this embodiment is connected to the driving seat 21, and the pressure sensor 6 has a display screen that can display torque. The pressure sensor 6 detects the reaction force exerted on the driving rod 22 when the grinding head 100 presses against the imitation bone, so as to know the pressure exerted by the grinding head 100 on the imitation bone, so as to meet the detection requirements of different pressures, and accurately control the pressure exerted by the grinding head 100 on the imitation bone during the detection process. In some other embodiments, the pressure sensor 6 can also be arranged on the limit seat 51, and the reaction force exerted on the driving rod 22 when the grinding head 100 presses down the imitation bone can also be detected by the pressure sensor 6.

[0065] Based on the above, the detection process of the grinding head 100 is: first, the imitation bone is clamped and positioned by the clamping mechanism 4, and the imitation bone is adjusted to the position to be ground; then the grinding head 100 is clamped by the positioning fixture 33, and then the angle between the grinding head 100 and the imitation bone is adjusted by rotating the fixture seat 32 to meet the detection angle requirement; the next step is to drive the positioning seat 31 to descend until the grinding head 100 abuts against the imitation bone. At this time, the pressure of the grinding head 100 on the imitation bone can be adjusted by controlling the descending distance of the grinding head 100, until the pressure of the grinding head 100 on the imitation bone reaches the preset value and stabilizes at the preset value. At this time, the limit member 52 abuts against the top of the driving rod 22 to limit the driving rod 22, thereby completing the preparation work.

[0066] Then, the tail end of the grinding head 100 is connected to the external driving component (i.e., the motor) to drive the positioning fixture 33 to rotate synchronously with the grinding head 100, so that the grinding head 100 grinds the simulated bone. The rotation speed of the motor simulates the rotation speed in the actual surgical operation, thereby simulating the actual surgical scene as much as possible. After a period of time, the motor stops working, and the grinding marks of the simulated bone are detected after the simulated bone is removed, so as to obtain the cutting force data of the grinding head 100.

[0067] After a single test is completed, the grinding head 100 can also be tested at other angles and other pressures according to the test requirements to simulate the operation scenarios of different grinding heads 100 at multiple angles and different pressures and obtain accurate test data.

[0068] Embodiment 2

[0069] Reference Figure 4 The difference between this embodiment and the first embodiment is that the sample in this embodiment is experimental skin, specifically animal epidermis; the surgical instrument in this embodiment is a cutting instrument, specifically a blade 200.

[0070] The detection process of this embodiment is: first, the animal skin is clamped and positioned by the clamping mechanism 4. It should be noted here that when clamping the animal skin, only the edge of the animal skin needs to be clamped, and the animal skin is spread horizontally to simulate the natural state of the human skin.

[0071] The blade 200 is then clamped by the positioning fixture 33, and the angle between the blade 200 and the test skin is adjusted by rotating the fixture seat 32. The positioning seat 31 is next driven down until the blade 200 abuts against the animal's epidermis and cuts the animal's epidermis. During this process, the sharpness data of the blade 200 can be obtained by observing the state of the animal's epidermis and recording the pressure exerted by the blade 200 on the animal's epidermis under various states of the animal's epidermis.

[0072] After a single inspection is completed, the blade 200 can be inspected at other angles according to inspection requirements to simulate the operation scenarios of different blades 200 at multiple angles and obtain accurate inspection data.

[0073] In addition, the sample in this embodiment may also be a surgical thread. If the surgical thread is to be cut, the two ends of the surgical thread need to be fixed between the first pressing block 42 and the second pressing block 43, which can be fixed by bonding or knotting.

[0074] Embodiment 3

[0075] Reference Figure 5 The difference between this embodiment and the second embodiment is that the surgical instrument in this embodiment is a puncture instrument, specifically a puncture needle 300, and the specific detection process thereof may refer to the second embodiment.
