Absorbable ligature clamp and manufacturing method thereof

Abstract

The invention discloses a ligature clamp which comprises a first clamp arm and a second clamp arm. Clamping projections are symmetrically arranged on the outer sides of the first clamp arm and the second clamp arm respectively, the reverse outer sides of the first clamp arm and the second clamp arm are of straight structures, the first clamp arm and the second clamp arm are of V-shaped structures in symmetrical shapes from the clamping projections on the respective sides to a connecting portion of the two clamp arms, a first cylindrical hollow portion is arranged in the first clamp arm, a second cylindrical hollow portion is arranged in the second clamp arm, and annular grooves are uniformly formed in the first hollow portion and the second hollow portion. The invention further provides a method for manufacturing the absorbable ligature clamp. By the aid of the clamp arms with the straight structures, the two clamp arms are of the basically symmetrical V-shaped structures, and an opening cannot shift in the closing process and is easily clamped and positioned. In addition, the absorbable ligature clamp can generate uniform fragments in the degrading process and is conveniently absorbed by human tissues.

Description

technical field [0001] The present invention relates to a medical instrument, especially a ligation clip used for anastomosis and ligation of blood vessels and tissues during a surgical operation and a manufacturing method thereof. In practical applications, the ligation clip is usually also called a blood vessel clip, Ligation buckles, surgical lock clips, tissue clips, etc. Background technique [0002] During abdominal surgery on the human body, once a lesion is found in the body and surgical resection is required, the blood vessels or tissues in the body need to be clamped temporarily, or even permanently. In the prior art, it is very common to use ligation clips to clamp and close blood vessels or tissues. [0003] For example, in the Chinese invention patent application CN 102973988 A that the applicant previously applied for and has been published, the background technology part has detailed descriptions on the types, types, development and evolution of ligature clip...

AI Technical Summary

Problems solved by technology

However, the structure of the arc-shaped clamp arm is complex, and the trajectory changes greatly when it is closed. In particular, the position of the opening will undergo a large displacement during the closing process. It requires special tools such as clip appliers to clamp and position it. Operators have high technical requirements and are not suitable for popularization and application

[0006] In addition, the existing ligation clips made of degradable materials are all naturally degraded by them, which means that during the degradation process, the ligation clips will be degraded into fragments of uneven size and then absorbed by human tissues, so the entire ligation clip The time and process of degradation are uncontrollable. If the fragments generated during the degradation of the ligation clip are large, they may dissociate to other positions and cause discomfort to the patient.
