Problems solved by technology

However, the effect of the practical application of the above two anti-falling hemostatic clips is limited
[0005] In summary, the existing technology still lacks a tissue clip that can meet the anti-deviation of absorbable materials and can meet the clinical needs

Abstract

The invention discloses an anti-deviation tissue holder. The anti-deviation tissue holder is made of absorbable high polymer material. The holder comprises a first clamping arm and a second clamping arm which are connected through an elastic hinge, first anti-deviation components which are composed of chain teeth staggered in sequence are arranged at the two sides of the center line of the inner wall surface of the first clamping arm along the center line of the first clamping arm, second anti-deviation components which are composed of chain teeth staggered in sequence are arranged at the twosides of the center line of the inner wall of the second clamping arm along the center line of the second clamping arm, and the chain teeth of the first anti-deviation components can be matched with the chain teeth of the second anti-deviation components to form a zipper shape. According to the anti-deviation components, sealing lines can be formed in the center lines of the clamping arms, exudation of the blood vessel can be prevented and the horizontal friction force can be increased to the greatest extent, horizontal deviation is avoided, the friction force of the side surface can be increased through anti-skid stripes, and vertical deviation is prevented.

Description

technical field [0001] The invention relates to a medical device, in particular to an anti-deviation tissue clip. Background technique [0002] Tissue clips, also known as vascular clips, ligation clips, and hemostatic clips, are used to clamp blood vessels and pipeline tissues in surgical operations (mainly minimally invasive laparoscopic operations). For example, it is used to clamp the cystic duct and cystic artery during cholecystectomy for patients with cholecystitis, calculous cholecystitis, and gallbladder polyps, and play the role of hemostasis and ligation and closure. The common method of early vessel or tissue ligation is needle-thread anastomosis, but needle-thread anastomosis has inevitable defects such as large vascular intima damage, complicated anastomosis operation, and long time-consuming. Therefore, since the advent of vascular clips, needle-thread anastomosis has gradually been replaced trend. The original vascular clips were mainly made of metal, such ...
