Description

Technical field

[0001] The invention relates to the technical field of medical sutures, in particular to a sustained-release antibacterial and absorbable medical sutures and a preparation method thereof. Background technique

[0002] Surgical suture thread refers to a special thread used for wound ligation, suture hemostasis and tissue suture in surgical operations. According to its biodegradability, it can be divided into two categories: non-absorbable thread and absorbable thread. Absorbable sutures include natural fibers and synthetic polymer sutures.

[0003] Chitosan is a natural fiber suture with good biocompatibility, antibacterial ability, chemical inertness, no foreign body reaction to tissues, etc. It can be absorbed by the human body, accelerates wound healing, and is not easy to cause irritation, allergies, Inflammation, and has the advantages of anti-inflammatory, promoting wound healing, and smooth wound after healing, but chitosan has poor mechanical properties and...
