PTFE surgical suture
It is a kind of safe, antibacterial and non rejection material with smooth surface, stable chemical resistance, not easy to be degraded and weakened by histomold, slight tissue reaction, and can maintain its strength in vivo for a long time.
With the development and progress of medicine and the improvement of people's living standards, people have higher and higher requirements for the quality of medical devices and materials. As one of the necessary surgical supplies in surgery, surgical suture is mainly used to suture wound and tissue and stop bleeding. Non absorbable surgical suture PTFE consists of suture and suture needle. PTFE suture is a single strand non absorbable surgical suture, which is chemically synthesized from 100% polytetrafluoroethylene without any additives. Polytetrafluoroethylene is generally referred to as "non stick coating" or "easy to clean material". This material is resistant to acid and alkali and various organic solvents, and almost insoluble in all solvents. At the same time, PTFE has the advantages of high temperature resistance and low friction coefficient. The suture needle is made of stainless steel. The needle types include round needle, angle needle, spade needle and so on, which are suitable for different surgical needs. PTFE suture is suitable for various types of soft tissue closure and ligation, including cardiovascular surgery, dentistry, general surgery and dural repair.
PTFE suture has good operation feel, no memory, good flexibility, high strength, stable biocompatibility, no tissue reaction and good operation characteristics. The outer diameter of the suture and the suture needle is close to 1:1. After the suture needle is penetrated in the suture operation, the space around the suture line is small, which can effectively reduce the bleeding of the needle eye.
