Ligation clip and clip cartridge device

By eliminating the clamping post in the design of the ligation clip, adding smooth, elongated protrusions and bosses, and optimizing the hook groove structure, the problems of scratching and snagging on instruments by existing polymer ligation clips have been solved, achieving a safer and more stable ligation effect.

AI Technical Summary

Technical Problem

Existing polymer ligation clips, when used to clamp blood vessels, often have many protruding and sharp points that can easily scratch or abrade internal tissues. Furthermore, they can easily get caught when medical devices are reinserted, causing inconvenience during operation.

Method used

Design a ligation clip by eliminating the clamping post on the first clamping arm and adding elongated protrusions and bosses on the second clamping arm, so that they form a smooth curved surface after engaging with the locking hook, reducing the number of protrusions and increasing the volume, reducing sharpness, and adding a fitting part and a locking part to the hook groove design to stabilize the locking.

Benefits of technology

It reduces scratches and abrasions to internal tissues caused by ligation clips, improves the ease of instrument operation, and enhances the stability and smoothness of locking.

Abstract

The application provides a ligature clip and a clip storage device, wherein the ligature clip comprises a first clip arm and a second clip arm, the first clip arm is formed with a locking hook, and the second clip arm is formed with a hook groove matched with the locking hook; the first clip arm has a first surface facing the second clip arm and a second surface facing away from the second clip arm, and a third surface and a fourth surface connecting the first surface and the second surface; the second clip arm has a fifth surface facing the first clip arm and a sixth surface facing away from the first clip arm, and a seventh surface and an eighth surface connecting the fifth surface and the sixth surface; the third surface and the fourth surface are flat and smooth; the seventh surface is provided with a first protrusion in a strip shape at a position close to the hook groove, the eighth surface is provided with a second protrusion in a strip shape at a position corresponding to the first protrusion, and the first protrusion and the second protrusion both extend outward beyond the hook groove; after the locking hook and the hook groove are matched, the second end of the first protrusion and the second end of the second protrusion are matched with the shape of the back of the locking hook and smoothly transition to the back of the locking hook. The ligature clip can reduce scratches and abrasions on the tissue in the body.
