Absorbable closure clip

Abstract

The invention belongs to the field of medical instruments, and particularly relates to an absorbable closing clip. The clip comprises an upper arm, a lower arm and a one-piece hinge part, and the upper arm and the lower arm are connected into a whole through the one-piece hinge part to form the absorbable closing clamp. The upper arm is provided with an upper arm back part and an upper arm inner belly part, a lock hole is formed in one end, far away from the connected hinge part, of the upper arm, and an upper arm clamping pile is arranged at the upper end, far away from the connected hinge part, of the upper arm and used for installing a closing clip and a clip applying instrument; and the lower arm is provided with a lower arm back part and a lower arm inner belly part, a lock pin is arranged at one end, far away from the connected hinge part, of the lower arm, the lock pin is matched with a lock hole formed in the upper arm, so that the closing clip can be absorbed to form full-locking closing, and a lower arm clamping pile is arranged at the upper end, far away from the connected hinge part, of the lower arm and is used for installing the closing clip and a clip applying instrument.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an absorbable closure clip. Background technique [0002] During medical and surgical operations, many luminal tissues in the body cavity need to be ligated and closed for a long time or temporarily, and the number of small and medium-sized luminal lumens such as bile ducts, arteries and veins is relatively large. With the continuous development of science and technology, endoscopic minimally invasive surgery has been widely used, and correspondingly, higher miniaturization requirements for closure clips have been put forward. At present, the micro-sized closure clips used in laparoscopic surgery are mainly made of stainless steel metal, titanium alloy metal, non-degradable polymer materials and biodegradable biomaterials. Among them, the closure clips made of metal materials and non-degradable polymer materials cannot be degraded and absorbed, and may cause foreign body react...

AI Technical Summary

Problems solved by technology

This kind of ligation and closure clip is composed of a single part and uses a buckle-type lock hook. Because of the same kind of material that is easy to soften when exposed to water, it is difficult to guarantee the final closure strength, resulting in a small scope of application and complete stripping of the tissue, resulting in complicated surgery. And the problem of insufficient safety performance during and after surgery
