A method for preparing an absorbable vessel clip

Abstract

An absorbable vessel clip includes a first clip arm and a second clip arm. By means of the two clip arms, large angle opening can be realized, and the blood vessel can be clamped conveniently. The clip consists of an absorbable bilayer of material. A preparation method mainly comprises the steps of stamping, injection molding and assembly.

Description

technical field [0001] The invention relates to a preparation method of an absorbable blood vessel clip. Background technique [0002] Minimally invasive surgery refers to a new technology that provides a surgical field of view through electronic mirrors such as laparoscopes and thoracoscopes, and performs surgery in the human body through instruments such as staplers. Due to the advantages of less trauma, less pain, and faster recovery, minimally invasive surgery has gradually gained popularity in medical treatment. In minimally invasive surgery, it is necessary to use vascular clips to stop bleeding from blood vessels. [0003] The existing blood vessel clamp includes a first clamp arm and a second clamp arm. During use, the blood vessel is clamped by the engagement of the first clamp arm and the second clamp arm to achieve hemostasis. However, due to the integrated structure of the first clamping arm and the second clamping arm, it is impossible to achieve large-angle o...

AI Technical Summary

Problems solved by technology

However, due to the integrated structure of the first clamp arm and the second clamp arm, large-angle opening cannot be achieved

If the material used for the vascular clip cannot be absorbed by the human body, the vascular clip left in the human body will be detrimental to health

Some existing vascular clips use absorbable materials, but the strength of the material is poor, resulting in insufficient clamping force of the hemostatic clip, and due to the short absorption cycle, it cannot provide durable clamping force
