Ligation clip

Abstract

The invention relates to a ligation clip, and belongs to medical materials. The ligature clip comprises two opposite clip arms and an elastic connecting part for connecting the two clip arms, each clip arm is provided with two opposite side faces and a clamping face for connecting the two side faces, the clamping face is concaved inwards to form a plurality of anti-falling grooves, and at least one clip arm is bent inwards or protrudes outwards to form a bent part. The anti-falling grooves are formed in the clamping face to increase the axial and radial anti-falling force, and the anti-falling grooves are of an inwards-concave structure, so that it is guaranteed that the anti-falling force is improved, blood vessels can be prevented from being punctured, and the safety of an operation is improved; by arranging the bent part, the blood vessels can be clamped in the bent part when the blood vessels are clamped, compared with an existing structure, the sliding force is larger, large blood vessels can be moved outwards to the two sides when the large blood vessels are clamped, the ligation clip can be suitable for blood vessels with different diameters, damage to the blood vessels is small, the blood vessel stretching force can be resisted, and the leakage prevention capacity is improved.

Description

technical field [0001] The invention relates to a ligation clip, which belongs to medical materials. Background technique [0002] The ligation clip is suitable for the ligation of blood vessels or other tubular structures in clinical laparoscopic surgery or surgical non-absorbable ligature clips. The ligation clip usually passes through two opposite clamp arms and an elastic connection part connecting the clamp arms. The existing ligation clips are usually There are the following problems: in order to improve the anti-off force of the existing ligation clip, some protruding particles are usually formed on the clamping surface of the clamp arm. It can achieve the anti-off force, but these protruding particles may be embedded in the blood vessel, thereby puncturing the blood vessel. In addition, the ligation clips of the prior art can only be used on blood vessels with a fixed size. If the size of the blood vessel changes, you need to Replace with another type of ligation cl...
