Problems solved by technology
However, in the process of normal operation, due to the structure of the end of the clip, the space between the tissues in the body will be interfered when the stone is grasped, so that the grasper cannot be grasped smoothly. At the same time, it only uses springs to keep the stones clamped between the clip and the spacer, and it is very easy to cause the stones to fall off due to loose hands. Therefore, a device is urgently needed to solve the problem

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0025] refer to Figure 1-4 , a combined urology stone grabber, including an L-shaped plate 1, a pull rod 2, a pad 3 and a splint 4, the pad 3 (the pad 3 is a cylindrical structure) is welded on the end of the pull rod 2, and the pull rod 2 The spring moves on the L-shaped plate 1, and the pull rod 2 can drive the cushion block 3 to move and adjust. There are two switches on the side wall of the L-shaped plate 1 (one controls the electric push rod on the U-shaped plate 31, and the other controls the straight line motor), and a U-shaped plate 31 is slid between the inner walls of the L-shaped plate 1, which has an auxiliary guiding effect on the movement of the pad 3,...

The invention relates to the technical field of medical devices, in particular to a combined urology stone grabber, comprising an L-shaped plate, a pull rod, a pad and a splint, the pad is welded to the end of the pull rod, and the pull rod moves in the L through a spring. There are two switches on the side wall of the L-shaped plate, and a U-shaped plate is slid between the inner walls of the L-shaped plate. The U-shaped plate is welded on the pad, and the top of the U-shaped plate is electrically pushed The rod is movable with a movable block, and the upper part of the movable block is welded with a sticker on the inner top wall of the U-shaped plate along its sliding track. Both the sticker and the surface of the movable block are provided with pointed protrusions. The sticker One side of the L-shaped plate is welded with a guide seat on the inner top wall of the L-shaped plate, and a guide plate is slid by a linear motor on the bottom wall of the guide seat. The present invention can not only timely adjust the direction of the splint according to the environment where the stone is located, so as to better grasp the stone, but also avoid the falling of the stone during the process of taking it out.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined stone grabber for urology. Background technique [0002] During the operation of urology surgery, it is often necessary to use the stone grabber to grab the stones in the patient's body and then take them out, and then suture the surgical wound. Tweezers or pincers with pointed tips. [0003] The Chinese invention patent with the notification number CN111991054A discloses a urological calculus grabber. The grabber places clips and spacers on both ends of the calculus, and then presses down on the support plate with your fingers to force the spring to compress and drive the clip. The disc clamps the stone on the spacer, and finally the stone can be stably removed from the patient. However, in the process of normal operation, due to the structure of the end of the clip, the space between the tissues in the body will be interfered when the stone is grasped, so t...
