[0028] Example:

[0029] See also Figure 1 、 Figure 2 and Figure 4 A clinical stone removal device that can be firmly clamped includes a base column 1, the left and right ends of the bottom outer wall of the base column 1 are fixedly connected with a telescopic rod 3, the left and right ends of the bottom wall of the base column 1 are rotatably connected with a clamping rod 4, and a two-way electric push rod 9 is provided on the adjacent side of the two clamping rods 4. The output end of the two-way electric push rod 9 is fixedly connected to the outer wall of the clamping rod 4, the outer wall of the left clamping rod 4 is fixedly connected to a first fixed block 5, and the outer wall of the first fixed block 5 is equidistantly fixed with a plurality of clamping columns 7, the outer wall of the right clamping rod 4 is fixedly connected to a second fixed block 6, and the outer wall of the second fixed block 6 is equidistantly fixed with a plurality of clamping cylinders 8, the clamping columns 7 and the clamping cylinders 8 are engaged, and a positioning mechanism 2 is provided on the front side of the base column 1.

[0030] This solution can control the movement of the clamping rod 4 at the left and right ends of the bottom wall of the base column 1 by starting the bidirectional electric push rod 9, so that the stone can be clamped by adjusting the position of the clamping rod 4. The left and right ends of the outer wall of the clamping rod 4 are respectively fixed with the first fixed block 5 and the second fixed block 6. The device can be connected by the engagement of the clamping column 7 and the clamping cylinder 8. The clamping column 7 and the clamping cylinder 8 can provide a certain degree of sealing for the device, so that stones of different shapes can be stably clamped, thereby improving work efficiency.

[0031] See also Figure 1 and Figure 3The positioning mechanism 2 includes a rack 201, which is fixedly connected to the front end of the outer wall of the base column 1, and a sliding plate 202 is fixedly connected to the outer wall of the base column 1. The outer wall of the sliding plate 202 is fixedly connected to a first connecting column 203, and the outer wall of the first connecting column 203 is rotatably connected to a worm gear 205.

[0032] In this solution, the worm 208 and the worm wheel 205 can be meshed and transmitted by rotating the rotating wheel 209, so that the worm wheel 205 and the rack 201 can be transmitted. Since the rack 201 is fixed to the outer wall of the base column 1, it can drive the base column 1 to move up and down. Therefore, by adjusting the rotating wheel 209, medical staff can stably control the position of the clamping component, thereby improving the stability and accuracy of the operation.

The clamping column 7 and the clamping cylinder 8 are fixed on the outer walls of the first fixed block 5 and the second fixed block 6 respectively. Because the rotation trajectory of the clamping rod 4 is fan-shaped, the clamping column 7 and the clamping cylinder 8 can only be preliminarily engaged to prevent the device from getting stuck. The engagement of the clamping column 7 and the clamping cylinder 8 can improve the stability and sealing of the clamping part, and the stones can be controlled within the two fixed blocks, thereby improving the stability of the device clamping. , to prevent it from falling off, so that the stone can be taken out through the positioning mechanism 2, and the base column 1 is fixed to the mounting block 11 by the telescopic rods 3 at the left and right ends, so it can be moved in conjunction with the positioning mechanism 2, and the medical staff can manually rotate the rotating wheel 209 to drive the worm 208 to rotate, so that the worm 208 and the worm wheel 205 can be engaged and transmitted, so that the rack 201 on the outer wall of the base column 1 can be connected to the worm wheel 205, and then the telescopic rod 3 can be used to move the base column 1, and the specific position where the stone needs to be clamped can be stably adjusted to improve the stability of the device.
