[0002] As an orthopedic implant, the dimensional accuracy of a bone plate is crucial during fracture fixation and treatment, directly affecting the surgical outcome, the quality of bone healing, and the patient's recovery process.

[0003] In related technologies, the length of a bone plate is usually detected manually, with low detection efficiency and inaccurate detection results due to human factors. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in related technologies to some extent. To this end, an embodiment of the present invention provides a bone plate length detection device, which can improve the detection efficiency and detection accuracy.

[0005] The present invention also provides a bone plate length detection method.

[0006] The bone plate length detection device according to the embodiment of the present invention includes a detection component and a clamping component. The detection component includes a first detection part and a second detection part that can approach or move away from each other along a preset direction. The first detection part includes a first power output member, and a first stop member is provided at the output end of the first power output member. The first stop member is used to abut against one end of the bone plate. The second detection part includes a second power output member, and a second stop member is provided at the output end of the second power output member. The second stop member is used to abut against the other end of the bone plate. The clamping component is arranged on one side of the detection component. The clamping component includes a clamping member for clamping the bone plate and an adjustment component for adjusting the movement of the clamping member. During detection, the adjustment component is used to move the clamping member to clamp the bone plate between the first stop member and the second stop member, and can keep the bone plate in a static state when the first stop member and the second stop member respectively abut against both ends of the bone plate in the preset direction.

[0007] When using the bone plate length detection device in this embodiment, the first stopper and the second stopper are respectively in the first original position and the second original position, and the initial distance S between the first original position and the second original position is calculated. Then, the bone plate is clamped by the clamping member. After the bone plate is fixed by the clamping member, the clamping member is driven to move by the adjusting member, so that the clamping member drives the bone plate to move between the first detection portion and the second detection portion. The first stopper is driven by the first power output member to approach the bone plate until the first stopper abuts against the bone plate. At the same time, the second stopper is driven by the second power output member to approach the bone plate until the second stopper abuts against the bone plate. The moving distances of the first stopper and the second stopper are respectively recorded, and the sum Y of the moving distances of the first stopper and the second stopper is obtained. Thus, the length of the bone plate to be detected can be obtained by subtracting the sum Y of the moving distances of the first stopper and the second stopper from the initial distance S between the first stopper and the second stopper, without manual measurement, which is beneficial to improving the detection accuracy and detection efficiency. And in this detection device, the bone plate is directly clamped by the clamping assembly and then directly detected after being moved to the detection point.

And / or, the clamping assembly further includes a second moving member, the second moving member has an output end that can move along the preset direction, and the adjusting member is arranged at the output end of the second moving member.

Detailed Embodiments

[0023] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] Embodiment 1 In this embodiment, as Figure 1 shown, the bone plate length detection device includes a detection assembly 1 and a clamping assembly 2. The detection assembly 1 includes a first detection part 11 and a second detection part 12 that can approach or move away from each other along a preset direction. The first detection part 11 includes a first power output member 111, and a first stop member 112 is provided at the output end of the first power output member 111. The first stop member 112 is used to abut against one end of the bone plate 100. The second detection part 12 includes a second power output member 121, and a second stop member 122 is provided at the output end of the second power output member 121. The second stop member 122 is used to abut against the other end of the bone plate 100. The clamping assembly 2 is arranged on one side of the detection assembly 1. The clamping assembly 2 includes a clamping member 22 for clamping the bone plate 100 and an adjusting member 21 for adjusting the movement of the clamping member 22. During detection, the adjusting member 21 is used to move the clamping member 22 to clamp the bone plate 100 between the first stop member 112 and the second stop member 122, and can keep the bone plate 100 in a stationary state when the first stop member 112 and the second stop member 122 respectively abut against both ends of the bone plate 100 in the preset direction.

[0025] For example, both the first stop member 112 and the second stop member 122 can be plate-shaped to increase the contact surface for facilitating the abutment of the first stop member 112 and the second stop member 122 against the bone plate 100.

[0026] Specifically, when the adjusting member 21 moves the position of the bone plate 100 clamped by the clamping member 22, the bone plate 100 is adjusted so that the length direction to be detected of the bone plate 100 is consistent with the preset direction.

[0027] When using the bone plate length detection device in this embodiment, the first stopper 112 and the second stopper 122 are respectively in the first original position and the second original position, and the initial distance S between the first original position and the second original position is calculated. Then, the bone plate 100 is clamped by the clamping member 22. After the bone plate 100 is fixed by the clamping member 22, the clamping member 22 is driven to move by the adjusting member 21, so that the clamping member 22 drives the bone plate 100 to move between the first detection portion 11 and the second detection portion 12. The first stopper 112 is driven by the first power output member 111 to approach the bone plate 100 until the first stopper 112 abuts against the bone plate 100. At the same time, the second stopper 122 is driven by the second power output member 121 to approach the bone plate 100 until the second stopper 122 abuts against the bone plate 100. The moving distances of the first stopper 112 and the second stopper 122 are respectively recorded, and the sum Y of the moving distances of the first stopper 112 and the second stopper 122 is obtained. Thus, the length of the bone plate 100 to be detected can be obtained by subtracting the sum Y of the moving distances of the first stopper 112 and the second stopper 122 from the initial distance S between the first stopper 112 and the second stopper 122, without manual measurement, which is beneficial to improving the detection accuracy and detection efficiency. In this detection device, after the bone plate 100 is clamped and moved to the detection position by the clamping assembly 2, the detection is directly carried out. Before and after the detection of the bone plate 100, there is no need for the clamping assembly 2 to place and grasp the bone plate 100 at the corresponding detection position, which simplifies the detection steps and improves the detection efficiency.

[0028] The detection device of this embodiment includes a controller, which can be electrically connected to the detection assembly 1 and the clamping assembly 2, and can control the movement and stop of the first detection portion 11 and the second detection portion 12 in the detection assembly 1, and can also control the clamping member 22 in the clamping assembly 2 to clamp the bone plate 100, and control the adjusting member 21 to adjust the position of the bone plate 100, so as to realize the automation of the detection process and improve the detection efficiency and detection consistency.

[0029] In this embodiment, the detection assembly 1 further includes a distance detection member (not shown in the figure), and the distance detection member is configured to obtain the displacement information of the first detection portion 11 and the second detection portion 12. Specifically, the moving distances of the first stopper 112 and the second stopper 122 can be measured.

[0030] For example, the distance detection member can be a displacement sensor. Displacement sensors are respectively provided corresponding to the first detection portion 11 and the second detection portion 12 to respectively obtain the displacement information of the first detection portion 11 and the second detection portion 12. The specific structure and working principle of the displacement sensor are conventional prior arts and will not be elaborated here.

[0031] The moving distances of the first stopper 112 and the second stopper 122 can also be measured by other methods. For example, a laser rangefinder or a camera can be used to capture images for detection. The solutions of using a laser rangefinder or a camera to capture images are all conventional existing technologies.

[0032] In this embodiment, the outer end faces of the first stopper 112 and the second stopper 122 are opposite to each other and are both vertically arranged.

[0033] It can be understood that by arranging the end faces of the first stopper 112 in contact with the bone plate 100 and the end faces of the second stopper 122 in contact with the bone plate 100 to be opposite to each other and both vertically arranged, the first stopper 112 and the second stopper 122 can be accurately aligned with the edge of the bone plate 100 to be measured, which is beneficial to ensuring the accuracy of the measurement result.

[0034] In this embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the detection assembly 1 further includes a first moving member 13. The first moving member 13 includes a first guide rail 131 extending along a preset direction. The first detection portion 11 and the second detection portion 12 are both slidably disposed on the first guide rail 131.

[0035] It can be understood that by providing the first guide rail 131 and slidably disposing the first detection portion 11 and the second detection portion 12 on the first guide rail 131, the first guide rail 131 can guide the first detection portion 11 and the second detection portion 12 along the preset direction, avoiding skewing during the movement of the first detection portion 11 and the second detection portion 12, which may result in inaccurate measurement of the length of the bone plate 100 in the direction to be measured, improving the stability of the movement of the first detection portion 11 and the second detection portion 12, and thus being beneficial to improving the accuracy of the detection result.

[0036] In this embodiment, as Figure 1 and Figure 3 shown, the first detection portion 11 further includes a first slider 113. The first slider 113 is connected to the first guide rail 131. The first power output member 111 drives the first slider 113 to slide along the first guide rail 131. The second detection portion 12 further includes a second slider 123. The first slider 113 is connected to the first guide rail 131. The second power output member 121 drives the second slider 123 to slide along the first guide rail 131.

[0037] The controller is electrically connected to both the first power output member 111 and the second power output member 121, and controls the first power output member 111 and the second power output member 121 to drive the movement of the first slider 113 and the second slider 123 respectively.

[0038] Specifically, a first conveying mechanism is provided on the first guide rail 131. For example, the first conveying mechanism includes a rack. The first power output member 111 includes a first driving member and a first gear. The first driving member can be a servo motor. The first driving member is disposed on the first slider 113, and the first gear is disposed at the output end of the first driving member. The first driving member can drive the first gear to rotate. The first gear meshes with the rack. When the first driving member drives the first gear to rotate, the first slider 113 is driven to slide along the first guide rail 131 through the meshing of the first gear and the rack. Similarly, the second power output member 121 includes a second driving member and a second gear. The second driving member can be a servo motor. The second driving member is disposed on the second slider 123, and the second gear is disposed at the output end of the second driving member. The second driving member can drive the second gear to rotate. The second gear meshes with the rack. When the second driving member drives the second gear to rotate, the second slider 123 is driven to slide along the first guide rail 131 through the meshing of the second gear and the rack. Of course, those skilled in the art can also set the first power output member 111 and the second power output member 121 in other forms. The first detection unit 11 and the second detection unit 12 can both perform relative sliding with the first guide rail 131 in the form of a worm and worm gear or a ball screw, which is not limited herein.

[0039] Specifically, the first power output member 111 drives the first slider 113 to slide along the first guide rail 131. The first stopper 112 can be disposed on the first slider 113, and the first slider 113 can drive the first stopper 112 to stably move along the first guide rail 131, and it is convenient for the installation of the first stopper 112. Similarly, the second power output member 121 drives the second slider 123 to slide along the first guide rail 131. The second stopper 122 can be disposed on the second slider 123, and the second slider 123 can drive the second stopper 122 to stably move along the first guide rail 131, and it is convenient for the installation of the second stopper 122.

[0040] In this embodiment, as Figures 1 to 3 shown, the adjusting member 21 of the clamping assembly 2 includes a first rotation driving member 211 and a second rotation driving member 212. The first rotation driving member 211 has an output end that can rotate around the A axis. The second rotation driving member 212 is disposed at the output end of the first rotation driving member 211. The second rotation driving member 212 has an output end that can rotate around the B axis perpendicular to the A axis. The clamping member 22 is disposed at the output end of the second rotation driving member 212.

[0041] It can be understood that the second rotation driving member 212 is disposed at the output end of the first rotation driving member 211. The first rotation driving member 211 can drive the second rotation driving member 212 to rotate around the A axis. The second rotation driving member 212 can drive the bone plate 100 clamped by the clamping member 22 to rotate around the A axis through the clamping member 22. The second rotation driving member 212 can also drive the clamping member 22 to rotate around the B axis perpendicular to the A axis, so that the bone plate 100 can rotate around both the A axis and the B axis, and further the bone plate 100 can achieve adjustment in different orientations, which is convenient for measuring the bone plate 100 and also convenient for measuring the lengths of the bone plate 100 in different directions.

[0042] In this embodiment, as Figure 3 shown, the first rotation driving member 211 includes a third driving member 2111 and a first mounting table 2112. The first mounting table 2112 is disposed at the output end of the third driving member 2111, and the second rotation driving member 212 is disposed on the first mounting table 2112. The second rotation driving member 212 includes a fourth driving member 2121 and a second mounting table 2122. The fourth driving member 2121 is disposed at the output end of the first rotation driving member 211, the second mounting table 2122 is disposed at the output end of the fourth driving member 2121, and the clamping member 22 is disposed on the second mounting table 2122.

[0043] The controller is electrically connected to both the third driving member 2111 and the fourth driving member 2121, and controls the third driving member 2111 to drive the second rotation driving member 212 to rotate around the A axis through the first mounting table 2112, so as to drive the bone plate 100 clamped by the clamping member 22 to rotate through the second rotation driving member 212. The fourth driving member 2121 is controlled to drive the bone plate 100 clamped by the clamping member 22 to rotate around the B axis through the second mounting table 2122.

[0044] For example, both the third driving member 2111 and the fourth driving member 2121 can be servo motors. Using servo motors for driving is beneficial to accurately adjust the position of the bone plate 100.

[0045] Specifically, the first mounting table 2112 has a first connecting portion and a first mounting portion. The first mounting table 2112 is connected to the output end of the third driving member 2111 through the first connecting portion. The first mounting portion has a first mounting surface, and the fourth driving member 2121 can be mounted on the first mounting surface of the first mounting portion. The structures of the first connecting portion and the first mounting portion can be set according to actual requirements and are not limited herein. The second mounting table 2122 has a second connecting portion and a second mounting portion. The second mounting table 2122 is connected to the output end of the fourth driving member 2121 through the second connecting portion. The second mounting portion has a second mounting surface, and the clamping member 22 can be mounted on the second mounting surface of the second mounting portion. Similarly, the structures of the second connecting portion and the second mounting portion can be set according to actual requirements and are not limited herein.

[0046] It can be understood that the first rotation driving member 211 includes a third driving member 2111 and a first mounting table 2112. The third driving member 2111 can provide a driving force for rotation about the A axis, and the first mounting table 2112 can facilitate the installation of the second rotation driving member 212. Similarly, the second rotation driving member 212 includes a fourth driving member 2121 and a second mounting table 2122. The fourth driving member 2121 can provide a driving force for rotation about the B axis, and the second mounting table 2122 can facilitate the installation of the clamping member 22.

[0047] In this embodiment, as Figure 1 and Figure 2 shown, the clamping assembly 2 further includes a positioning member 23. The positioning member 23 is located outside the clamping member 22 to cooperate with the clamping member 22 to position the bone plate 100.

[0048] Specifically, the positioning member 23 is disposed at the output end of the second rotation driving member 212 and can move synchronously with the clamping member 22. Further, the positioning member 23 can be disposed on the second mounting table 2122 and is located at the side of the clamping member 22.

[0049] It can be understood that when the clamping member 22 clamps the bone plate 100, the bone plate 100 cannot be accurately positioned. By providing the positioning member 23 to cooperate with the clamping member 22 to position the bone plate 100, the positioning accuracy of the bone plate 100 can be improved, which is beneficial to improving the reliability of the detection result of the length of the bone plate 100.

[0050] In this embodiment, as Figure 2 shown, the positioning member 23 includes two support plates 231. The two support plates 231 are respectively located on both sides of the clamping member 22 and are used to support the bone plate 100.

[0051] Since the two support plates 231 of the positioning member 23 are respectively located on both sides of the clamping member 22, the two support plates 231 form supports for both ends of the bone plate 100, and the bone plate 100 can be stably placed on the support plates 231. Thus, when the clamping member 22 clamps the bone plate 100, the bone plate 100 can be prevented from shaking and skewing, which may cause inaccurate clamping of the bone plate 100 and affect the accuracy of the detection result.

[0052] In this embodiment, as Figure 2 shown, the clamping member 22 includes two opposite clamping jaws. The inner surfaces of the two clamping jaws are parallel to each other, and the inner surface of the clamping jaw is perpendicular to the upper surface of the support plate 231.

[0053] For example, the clamping member 22 further includes a driving cylinder, and the two jaws are respectively connected to the driving cylinder. The driving cylinder drives the two jaws to approach or separate from each other to clamp or release the bone plate 100. By driving the jaws with the driving cylinder, the response speed can be increased and the structure of the clamping member 22 can be simplified. Specifically, the driving cylinder is electrically connected to the controller, and the controller controls the driving cylinder to drive the two jaws to approach or separate from each other.

[0054] It can be understood that the inner surface of the jaw and the upper surface of the support plate 231 are perpendicular. When the clamping member 22 clamps the bone plate 100, the bone plate 100 can be positioned from two mutually perpendicular directions perpendicular to the inner surface and perpendicular to the upper surface of the support plate 231, which can ensure the positioning accuracy and stability of the positioning.

[0055] In this embodiment, as Figure 1 and Figure 3 shown, the clamping assembly 2 further includes a second moving member 24. The second moving member 24 has an output end that can move along a preset direction, and the adjusting member 21 is arranged at the output end of the second moving member 24.

[0056] Specifically, in this embodiment, the second moving member 24 includes a second guide rail 241 and a third slider 242. The second guide rail 241 and the first guide rail 131 are arranged in parallel at intervals. The second guide rail 241 is connected with a fifth driving member 243 and a second transmission mechanism connected to the output end of the fifth driving member 243. The third slider 242 is slidably arranged on the second guide rail 241 and connected to the execution part of the second transmission mechanism. The adjusting member 21 is fixed on the third slider 242. The controller is electrically connected to the fifth driving member and controls the fifth driving member 243 to drive the second transmission mechanism to operate, so as to drive the third slider 242 to move along the second guide rail 241 through the second transmission mechanism.

[0057] For example, the fifth driving member 243 is a servo motor, and the second transmission mechanism can be a belt transmission mechanism or a lead screw transmission mechanism. By setting the fifth driving member 243 as a servo motor, the movement of the adjusting member 21 can be accurately controlled by accurately controlling the second transmission mechanism. The connection manner of the fifth driving member 243, the second transmission mechanism and the second guide rail 241 is a conventional existing technology and will not be elaborated here.

[0058] When the second moving member 24 drives the adjusting member 21 to move, the fifth driving member 243 drives the second transmission mechanism to operate, and drives the third slider 242 to move along the second guide rail 241 under the drive of the second transmission mechanism. Since the adjusting member 21 is arranged on the third slider 242, the third slider 242 can drive the adjusting member 21 to move when it moves.

[0059] In this embodiment, as Figure 1 and Figure 3As shown, the bone plate length detection device further includes a moving component 3. The moving component 3 includes a third guide rail 31, a fourth slider 32, a fifth slider 33, a third transmission mechanism, and a sixth driving member 35. Both the fourth slider 32 and the fifth slider 33 are arranged on the third guide rail 31. The first guide rail 131 is arranged on the fourth slider 32, and the second guide rail 241 is arranged on the fifth slider 33. The extending direction of the third guide rail 31 is orthogonally arranged with the extending directions of the first guide rail 131 and the second guide rail 241. The third transmission mechanism is arranged on the third guide rail 31 and connected to the output end of the sixth driving member 35. The sixth driving member 35 drives the fourth slider 32 and the fifth slider 33 to slide along the third guide rail 31 through the third transmission mechanism.

[0060] The controller is electrically connected to the sixth driving member 35, and controls the sixth driving member to drive the third transmission mechanism to operate, so as to drive the fourth slider 32 and the fifth slider 33 to move along the third guide rail 31 through the third transmission mechanism.

[0061] For example, the sixth driving member 35 can be a servo motor, and the third transmission mechanism can be a belt transmission mechanism. The specific setting manner of the third transmission mechanism on the third guide rail 31 is conventional prior art and will not be elaborated here. Further, the moving component 3 further includes a linkage rod 34. Two third guide rails 31 are arranged in parallel at intervals. The input ends of the third transmission mechanisms on the two third guide rails 31 are connected by the linkage rod 34, so that the third transmission mechanisms on the two third guide rails 31 are linked. One of the input ends of the two third transmission mechanisms is connected to the sixth driving member 35, so that when the sixth driving member 35 drives one third transmission mechanism to operate, the other third transmission mechanism is simultaneously linked through the linkage rod 34. The fourth slider 32 and the fifth slider 33 are arranged on each third guide rail 31. Both ends of the first guide rail 131 are arranged on two fourth sliders 32 respectively, and both ends of the second guide rail 241 are arranged on two fifth sliders 33 respectively, which is beneficial to enabling the first guide rail 131 and the second guide rail 241 to slide smoothly along the third guide rail 31.

[0062] The sixth driving member 35 drives the fourth slider 32 and the fifth slider 33 to move along the third guide rail 31 through the third transmission mechanism. It can drive the first guide rail 131 through the fourth slider 32 and drive the second guide rail 241 to move along the third guide rail 31 through the fifth slider 33, so as to drive the clamping component 2 and the detection component 1 to move along the third guide rail 31. Thus, the positions of the clamping component 2 and the detection component 1 can be adjusted along the extending direction of the third guide rail 31 as needed, increasing the movement range of the clamping component 2 and the detection component 1.

[0063] This embodiment may further include an output device (not shown in the figure) for outputting the length value of the bone plate 100 so that the measured length of the bone plate 100 can be obtained by people. The output device may be a display screen, a speaker, etc., for displaying or reporting the length value of the bone plate 100. Specifically, the output device is electrically connected to the controller, and the result output by the output device is controlled by the controller.

[0064] Embodiment Two In the bone plate length detection method of this embodiment, the above-mentioned bone plate length detection device is used. As Figure 5 shown, the bone plate detection method includes the following steps: S200, control the first stopper 112 and the second stopper 122 to be in the first original position and the second original position respectively, and calculate the initial distance S between the first original position and the second original position.

[0065] Specifically, the controller sets the first original position and the second original position of the first stopper 112 and the second stopper 122, and controls the first stopper 112 and the second stopper 122 to be located at the first original position and the second original position respectively before detection. At the same time, the controller calculates the initial distance S according to the first original position and the second original position.

[0066] S210, clamp the bone plate 100 by the clamping member 22.

[0067] S220, control the bone plate 100 clamped by the clamping member 22 to move to a preset position between the first stopper 112 and the second stopper 122, and keep the clamping member 22 in a static state.

[0068] Specifically, the controller sets the preset position of the bone plate 100 during detection, and sets the preset position between the first original position and the second original position to ensure that the first stopper 112 and the second stopper 122 of the detection assembly 1 can abut against both ends of the bone plate 100. The controller moves the clamping member 22 to this preset position by controlling the adjusting member 21. During this process, after the clamping member 22 directly clamps the bone plate 100, it immediately moves to the preset position and keeps clamping the bone plate 100, avoiding the operation of transferring the clamped bone plate 100 to the detection point for placement, simplifying the detection steps, and improving the detection efficiency.

[0069] S230, control the first stopper 112 and the second stopper 122 to move relatively until they respectively abut against both ends of the bone plate 100 along the preset direction, and record the moving distances of the first stopper 112 and the second stopper 122 respectively, and obtain the sum Y of the moving distances of the first stopper 112 and the second stopper 122.

[0070] The controller controls the first stopper 112 and the second stopper 122 to abut against both ends of the bone plate 100 along a preset direction, and obtains the sum Y of the moving distances of the first stopper 112 and the second stopper 122 during this process. Specifically, the controller drives the first stopper 112 to move by controlling the first power output member 111, and drives the second stopper 122 to move by controlling the second power output member 121.

[0071] S240, calculate the length L of the bone plate 100 = S - Y.

[0072] Specifically, the controller subtracts the sum Y of the moving distances of the first stopper 112 and the second stopper 122 during detection from the initial distance S between the first stopper 112 and the second stopper 122 when they are respectively at the first original position and the second original position, which has been obtained, to obtain the length L of the bone plate 100.

[0073] Embodiment III As Figure 6 shown, the detection method using the bone plate length detection device in Embodiment I includes the following steps: S300, control the first stopper 112 and the second stopper 122 to be respectively at the first original position and the second original position, and calculate the initial distance S between the first original position and the second original position.

[0074] Specifically, the controller sets the first original position and the second original position of the first stopper 112 and the second stopper 122, and controls the first stopper 112 and the second stopper 122 to be respectively at the first original position and the second original position before detection. At the same time, the controller calculates the initial distance S according to the first original position and the second original position.

[0075] S310, control the clamping assembly 2 to be at the third original position.

[0076] Specifically, the third original position is a position convenient for clamping the bone plate 100.

[0077] S320, place the bone plate 100 at an appropriate position on the pallet 231, and control the two jaws of the clamping member 22 to move closer to each other until the inner surfaces of the two jaws both abut against the bone plate 100 to fix the bone plate 100.

[0078] Specifically, when in the third original position, the clamping member 22 in the clamping assembly 2 remains in a vertical state, and the controller can control the jaws to clamp in the horizontal direction perpendicular to the vertical direction. The upper surface of the support plate 231 is perpendicular to the vertical direction. By using the jaws to clamp the portions on both sides of the bone plate 100 that are substantially parallel, and using the support plate 231 to support two spaced positions of the bone plate 100, the positioning of the bone plate 100 can be achieved, ensuring that the measured length value during detection is the length value of the bone plate 100 in the required direction. For a special-shaped bone plate, it can be selected to place the special-shaped bone plate on a specific fixture, and the fixture is clamped and fixed by the support plate 231 and the jaws to ensure obtaining the length value of the special-shaped bone plate in the required direction.

[0079] S330, control the second moving member 24 to move the clamping assembly 2 from the third original position to one side of the preset position between the first detection portion 11 and the second detection portion 12.

[0080] Specifically, the controller can control the fifth driving member 243 to drive the second transmission mechanism, so that the second transmission mechanism drives the third slider to slide along the second guide rail, thereby moving the clamping assembly 2 as a whole to one side of the preset position between the first detection portion 11 and the second detection portion 12.

[0081] S340, control the adjusting member 21 to flip the clamping member 22, so that the bone plate 100 is located at the preset position between the first detection portion 11 and the second detection portion 12 and remains stationary.

[0082] For example, when the A axis is in a horizontal state and the B axis is in a vertical state, the controller controls the adjusting member 21 to move the bone plate 100 clamped by the clamping member 22 to the preset position, which may mean controlling the first rotation driving member 211 of the adjusting member 21 to rotate 90° around the A axis, and the first rotation driving member 211 drives the clamping member 22 to flip 90° around the A axis through the second rotation driving member 212, so that the bone plate 100 flips 90° to the preset position.

[0083] S350, control the first detection portion 11 to move to one end of the bone plate 100. When the first stopper 112 abuts against one end of the bone plate and the force on the first stopper 112 reaches the preset external force value, control the first detection portion 11 to stop moving and record the moving distance Y1 of the first detection portion 11.

[0084] Specifically, the controller sets a preset external force value for the first stopper 112. When the controller determines that the external force received by the first stopper 112 reaches the preset external force value, it controls the first power output member 111 to stop driving the first slider 113 of the first detection unit 11 to continue moving along the first guide rail 131, so as to keep the first stopper 112 in contact with one end of the bone plate 100 and not move further, avoiding damage to the bone plate 100. At the same time, the controller controls the displacement sensor on the first detection unit 11 to detect the moving distance Y1 of the first detection unit 11.

[0085] Among them, the external force value received by the first stopper 112 can be obtained by setting a pressure sensor on the first stopper 112. The pressure sensor is connected to the controller, and the controller determines whether the external force value received by the first stopper 112 reaches the preset external force value.

[0086] It can be understood that the external force value received by the first stopper 112 can also be converted into a torque value for judgment by the controller. Specifically, when the first stopper 112 abuts against the bone plate 100, a force will act on the first power output member 111. For example, when the first power output member 111 includes a servo motor, the torque reaction received by the servo motor reflects the force acting on the first stopper 112. Therefore, a torque sensor can be set on the first power output member 111 to detect the torque received by the first power output member 111. The torque sensor sends the received torque value to the controller, and the controller converts the torque value received by the first power output member 111 into the external force value received by the first stopper 112, and then determines whether the force on the first stopper 112 reaches the preset external force value.

[0087] S360, control the second detection unit 12 to move to the other end of the bone plate 100. When the second stopper 122 abuts against the other end of the bone plate 100 and the force received by the second stopper 122 reaches the preset external force value, control the second detection unit 12 to stop moving, and record the moving distance Y2 of the second detection unit 12.

[0088] Specifically, the controller sets a preset external force value for the second stopper 122, and controls that when the second stopper 122 receives the preset external force value, the second power output member 121 stops driving the second slider 123 of the second detection unit 12 to continue moving along the first guide rail 131, so as to keep the second stopper 122 in contact with the other end of the bone plate 100 and not move further. At the same time, the controller controls the displacement sensor on the second detection unit 12 to detect the moving distance Y2 of the second detection unit.

[0089] The working principle of the second detection unit 12 is the same as that of the first detection unit 11, and will not be elaborated here.

[0090] S370, calculate the sum Y of the moving distances of the first detection unit 11 and the second detection unit 12.

[0091] Specifically, the controller calculates based on the values of Y1 and Y2 to obtain the sum Y of the moving distances of the first detection unit 11 and the second detection unit 12.

[0092] S380, calculate the length L of the bone plate 100 = S - Y.

[0093] S390, control the first detection unit 11, the second detection unit 12 and the clamping assembly 2 to return to their respective initial positions.

[0094] Specifically, the controller controls the first power output member 111 to drive the first slider 113 to move along the first guide rail 131 to the first original position; the controller controls the second power output member 121 to drive the second slider 123 to move along the first guide rail 131 to the second original position; the controller controls the first driving member and the second driving member to rotate so that the clamping member 22 returns to keep the jaws facing upward, and then controls the fifth driving member 243 to drive the second transmission mechanism so that the third slider 242 moves along the second guide rail 241 to make the clamping assembly 2 return to the third original position.

[0095] In this embodiment, after the bone plate 100 is fixed to the clamping member 22, the automatic detection of the length of the bone plate 100 can be realized, which is beneficial to improving the detection accuracy and detection efficiency.
