Anti-infective medical absorbable suture line

Abstract

The invention discloses an anti-infection medical absorbable suture, which comprises the following components in parts by weight: 55-75 parts of polylactic acid, 2-8 parts of squalane, 1-3 parts of pimaric acid, poly 4-12 parts of sorbitol ester, 20-30 parts of corn starch, 5-11 parts of lecithin, 3-5 parts of three yellow powder, 5-15 parts of white moss bark powder, 3-10 parts of lemon peel pectin, sodium alginate 11‑14 parts, 3‑8 parts of metronidazole, 10‑15 parts of dried blood powder, 5‑8 parts of tricalcium phosphate. An anti-infection medical absorbable suture thread of the present invention has good blood compatibility and tissue compatibility, high mechanical properties, can effectively prevent wound infection, degrades and absorbs, and the degradation products are safe and non-toxic to the human body, non-toxic and non-toxic. Stimulate.

Description

technical field [0001] The invention belongs to the field of biomedical materials, in particular to an anti-infection medical absorbable suture thread. Background technique [0002] Biomaterials are a class of high-tech materials used to diagnose, repair or enhance the functions of human tissues and organs, that is, natural or artificial materials used to replace and repair living tissues, and their functions cannot be replaced by drugs. Biomaterials can perform, enhance or replace a certain function lost due to disease, injury, etc., but cannot restore the defective part. Since the late 1990s, the world's biomaterial science and technology have developed rapidly. Even in today's global economic downturn, biomaterials still maintain a rapid growth rate of 13% per year, which fully reflects its strong vitality and broad development prospects. Modern medicine is developing in the direction of regeneration and reconstruction of damaged human tissues and organs, recovery and en...

AI Technical Summary

Problems solved by technology

However, most of the absorbable sutures commonly used in the medical field are catgut and chemically synthesized polymer threads, which have poor biocompatibility, easy to cause tissue immune reactions, insufficient absorption and poor mechanical properties when used.

At the same time, although the medical absorbable suture commonly used in the medical field is more outstanding in terms of absorbability, the effect is relatively single, so it is limited in use and needs to be further improved and improved.
