1, there is no absorbable suture for clinical surgical wound suture for a long time, in which natural and synthetic textile fibers are used as raw materials for surgical suture. Cotton fiber is one of the earliest raw materials for making surgical suture.
2, absorbable suture in modern clinical surgery, mainly used for abdominal, eye and other surgical incision suture. The earliest absorbable suture was made of collagen from gut mucosa and bovine gut mucosa, but after the surgical wound was sutured, the body tissue reacted strongly to gut suture, so now gut suture has been gradually replaced by a new type of surgical suture.
However, it is difficult to control the absorption period of absorbable suture, and relevant researchers are still trying to solve this problem.

Development history of surgical suture
The earliest record of surgical suture can be traced back to ancient Egypt in 3000 BC, and the oldest known suture is on the mummy in 1 100 BC. The first detailed written record about wound suture and the use of suture materials came from Suxuruta, a saint and doctor in India in 500 BC.
Hippocrates, the "father of medicine" in Greece, and Celsus in Rome later described the basic suture technique. The first person to describe intestinal suture was Roman doctor Galen in the 2nd century A.D., and some people thought it was Andalusian surgeon Zahrawi in the10th century A.D.. According to records, zahra Velluti's string was once swallowed by a monkey, and he discovered the absorbability of gut. Since then, medical catgut has been made.
Joseph lister introduced the great changes in suture technology, and he advocated routine disinfection of all suture lines. In the 65438+60s, he first tried to sterilize the "carbolic catgut" and then sterilized the chrome catgut 20 years later. 1906 sterile catgut treated with iodine.
The next leap took place in the 20th century. With the development of chemical industry, the first synthetic line was made in 1930s, and many absorption and non-absorption synthetic lines developed rapidly. The first synthetic line is polyvinyl alcohol of 193 1. Polyester thread was developed in 1950s, and then radiation sterilization of catgut thread and polyester was developed.
Poly (glycolic acid) was discovered in 1960s, and was used to make suture in 1970s. At present, most suture lines are made of polymer fibers. Only silk and catgut are still used in ancient materials-although they are not often used. In Europe and Japan, catgut is banned due to bovine spongiform encephalopathy, while silk is sometimes used for vascular and otolaryngology operations.
