[0032] The bending mechanism 200 comprises a first bending shaft 210, a second bending shaft 220, a rotating seat 230 and a bending driving unit 240. The first bending shaft 210 and the second bending shaft 220 are both in a cylindrical shape and extend upward and downward. The first bending shaft 210 is arranged on the adjusting block 250. The positioning seat 110 is provided with a guide groove 113 extending forward and backward. The adjusting block 250 is in an L shape. One end of the adjusting block 250 is slidingly arranged in the guide groove 113 and is fixed to the positioning seat 110 through two screws on the side. When the position of the first bending shaft 210 is adjusted, the one end of the adjusting block 250 slides along the guide groove 113 and is then fixed through a locking screw, so that the first bending shaft 210 is always kept on the right side of the slot of the positioning groove 111, and the side surface of the blade head of the surgical knife abuts against the outer periphery of the first bending shaft 210. The position of the adjusting block 250 is moved, so that the first bending shaft 210 is located at the position of the surgical knife, thereby changing the bending position.

[0033] The first bending shaft 210 is arranged at the other end of the adjusting block 250 and extends upward. The first bending shaft 210 is a wear-resistant component, that is, the first bending shaft 210 is made of wear-resistant material.

[0034] In other embodiments, the first bending shaft 210 can be arranged beside the positioning groove 111.

[0035] In this embodiment, the rotating seat 230 is in a circular ring shape, and the positioning mechanism 100 is fixedly arranged in the middle of the circular ring, so that the spatial layout of the rotating seat 230 and the positioning mechanism 100 is more reasonable. In other embodiments, the rotating seat 230 can be an arc-shaped plate. The bending driving unit 240 is in transmission connection with the rotating seat 230. In this embodiment, the bending driving unit 240 is a rotating motor. The output end of the rotating motor is provided with a transmission gear 241.

The rotating motor drives the transmission gear 241 to rotate, the transmission gear 241 drives the driven gear 242 to rotate, and the rotating seat 230 drives the corresponding rotating.

[0036] The rotating seat 230 is provided with a limiting groove 231.

The position of the second bending shaft 220 can be adjusted by adjusting the guide block 232.

[0037] Since the contact surface with the blade head will be worn during the bending process, the outer periphery of the top of the second bending shaft 220 is sleeved with a wear-resistant sleeve 221, so that the wear problem can be solved by replacing the wear-resistant sleeve 221. The bending driving unit 240 is used to drive the second bending shaft 220 to rotate so that the first bending shaft 210 and the second bending shaft 220 are respectively located on both sides of the surgical blade head to bend the surgical blade head. In order to position the wear-resistant sleeve 221, the second bending shaft 220 is provided with an annular step, and the lower end of the wear-resistant sleeve 221 abuts on the positioning annular step.

[0038] During bending, the shortest distance between the first bending shaft 210 and the second bending shaft 220 can be changed by adjusting the position of the first bending shaft 210 or the second bending shaft 220, so that the surgical blade head is bent at different positions, and the bending angle is adjusted by adjusting the rotation of the second bending shaft 220 relative to the first bending shaft 210.

[0039] It should be noted that the driving mechanisms of various driving units of the utility model are prior art, and the above-mentioned rotary motion, lifting motion and moving motion can all use cylinders, electric push rods and motor lead screws as driving units. In linear motion, corresponding slide rails are provided to improve the accuracy of motion, and in rotary motion, corresponding rotary shafts are provided to improve the accuracy and stability of rotation.

[0040] The bending angle measuring mechanism 300 comprises a three-axis moving assembly 310 and a detection sensor 320, and the three-axis moving assembly 310 is used to drive the detection sensor 320 to move on the X-axis, Y-axis and Z-axis. During detection, the detection sensor 320 can detect the position of the bent blade head end during bending, and then judge the bending shape.

[0041] The three-axis moving assembly 310 mainly comprises a base, a moving platform and a transmission mechanism.

[0042] The base is the base of the three-axis moving assembly 310, and is usually fixed on the workbench 500 to provide stable support for the moving platform; the moving platform is the working part on the three-axis moving assembly 310, and can move relatively on the X-axis, Y-axis and Z-axis. The moving platform is provided with a fixed rod, and one end of the fixed rod is provided with the detection sensor 320; the transmission mechanism comprises three guide rail guide devices and corresponding driving devices. The X-axis, Y-axis and Z-axis guide rail guide devices are respectively composed of corresponding guide rails and sliding blocks, and the sliding blocks are connected with the guide rails through rolling bearings and can move translationally on the corresponding shafts. The sliding blocks are provided with driving devices, and the movement of the sliding blocks on the shafts is controlled through the driving devices. The working principle of the three-axis moving assembly 310 is to control the driving devices of the X-axis, Y-axis and Z-axis to realize the movement control of the moving platform in three directions. The specific process is as follows:

[0043] X-axis movement: the slider moves forward and backward on the X-axis guide rail through the X-axis drive device, thereby driving the moving platform to move in the X-axis direction.

[0044] Y-axis movement: the slider moves left and right on the Y-axis guide rail through the Y-axis drive device, thereby driving the moving platform to move in the Y-axis direction.

[0045] Z-axis movement: the slider moves up and down on the Z-axis guide rail through the Z-axis drive device, thereby driving the moving platform to move in the Z-axis direction.

[0046] The reset mechanism 400 includes a first sensing module 410 and a second sensing module 420, the first sensing module 410 is arranged on the rotating seat 230, and the second sensing module 420 is fixedly arranged relative to the positioning mechanism 100.

[0047] The specific working principle is: in the preparation stage before the bending machine starts, the surgical knife head needs to be placed in the positioning groove 111 of the bending machine. At this time, the first sensing module 410 and the second sensing module 420 are in standby state, waiting for the arrival of the trigger signal; when the rotating seat 230 starts to rotate to reach the predetermined position, the relative distance or positional relationship between the first sensing module 410 and the second sensing module 420 will change. This subtle change is keenly captured by the second sensing module 420 and immediately converted into an electrical signal for transmission; after receiving this signal, the second sensing module 420 will perform a series of processing, and then feed back the processed result to the control system. The control system accurately records the current position of the rotating seat 230 according to this feedback signal, and sets it as the initial position; with this initial position as the starting point, the rotary drive unit can drive the rotating seat 230 to rotate according to the preset angle. This preset angle is the angle that the second rotating shaft needs to rotate in the bending process. The existence of the reset mechanism 400 provides a strong guarantee for the bending machine to maintain a stable running state during work. It can effectively avoid errors and faults caused by position deviation, thereby ensuring that the bending machine can complete the work task more efficiently and accurately. When the bending angle needs to be changed, the preset angle can be adjusted.

[0048] In the process of bending, the handle of the surgical knife is placed in the positioning groove 111, the pressing block 120 is driven to move downward by the pressing driving unit 130, the surgical knife is fixed in the pressing groove, meanwhile the head of the surgical knife is located at the side of the first bending shaft 210, the rotating seat 230 is driven to initialize the position by the bending driving unit 240, then the second bending shaft 220 is driven to rotate close to the head of the surgical knife by the bending driving unit 240, the first bending shaft 210 and the second bending shaft 220 are respectively located at the two sides of the head of the surgical knife and are staggered, the head of the surgical knife is bent by the continuous movement of the second bending shaft 220. In the process of bending, the position change of the head of the surgical knife is detected by the detection sensor 320, whether the bending is in place is judged by sensing the position change of the bending. In the process of bending, the shortest distance between the first bending shaft 210 and the second bending shaft 220 can be changed by adjusting the position of the first bending shaft 210 or the second bending shaft 220, so that the head of the surgical knife is bent at different angles.
