Absorbable suture is a new type of suture material that can be degraded and absorbed by the body after implantation into human tissue during surgical suturing, and does not need to be removed, thus eliminating the pain of suture removal. According to the degree of absorbability, they are classified as sheep intestine thread, polymer chemical synthetic thread, and pure natural collagen suture. The characteristics include tensile strength, biocompatibility, reliable absorption, and ease of operation. It is generally used for intracutaneous soft tissue suturing in gynecology, obstetrics, surgery, plastic surgery, urology, pediatric surgery, stomatology, otolaryngology, ophthalmology, etc.
