Description

A kind of surgical operation suturing new material
Technical field
The present invention relates to a kind of medical material field, specifically a kind of surgical operation suturing new material.
Background technique
Suture is common bio-compatible textile, is widely used in all kinds of surgical operations, to suture wound Mouthful, it is coupled tissue and ligation blood vessel.Early in B.C. 3500, ancient Egyptian was just sewed up a wound with cotton fiber, horse-hair, in Also early useful flaxen fiber makees the record of suture in the history records in state's ancient times.With the development of high polymer and its fiber, medical sutures The kind of line is also more and more.
There are many suture type, including absorbability and nonabsorbable suture.Many common natural and synthesis weavings Be used successfully as medical not absorbable suture line with fiber, the not absorbable suture line type developed at present have cotton, silk, Fiber crops, polyamide, polyester, polypropylene and metal suture line.Absorbable suture have casing, ossein, chitin, polyglycolide, The copolymer of glycolide and lactide gathers to dioxane ethyl ketone suture.
Suture must have the following performance requirement:
(1) intensity of line is higher, is not influenced and is deformed by body fluid, the not big change of mechanical property before wound healing Change；(2) flexibility of fiber is good, colludes with intensity height, is easy when suture by tissue, and when ligation is easy to operate, makes knots After hold knot property it is good；(3) biocompatibility is good, and tissue reaction is small, does not influence the growth of tissue；(4) for absorbability Suture should be absorbed completely after tissue repair, foreign matter is not left in human body；(5) stable and reliable product quality, Neng Gouchang Phase saves, and is easy to sterilize and invariance；(6) there is no toxicity, anaphylaxis, electrolyte, septic, carcinogenicity and capillarity.
As it can be seen that the quality requirement of suture is very high, but there are biocompatibilities that low, suture is being organized for current most of sutures Phenomena such as interior tensile strength is small and interferes normal wound healing is badly in need of researching and developing a kind of novel surgical operation suturing green wood Material.
Summary of the invention
