Surgical sutures

Surgical sutures which the surgery, or trauma dispose of them for hemostasis hemostasis and tissue suture special line.
Generally be divided into absorbable sutures and non-absorbable line:
Absorbable suture:
Absorbable suture according to the type of material and extent of absorption is divided into: catgut, and chemical synthesis (PGA), natural collagen suture.
1, catgut: based on the health of animal gut sheep made, containing collagen, after the suture does not require stitches. Medical catgut points: the ordinary catgut and chromic catgut two, can absorb. Absorption length of time required, depending on the thickness of the gut and organizations, generally 6 to 20 days can be absorbed, but patients are individual differences affect the absorption process, and even does not absorb. Gut disposable sterile packaging, easy to use.
(1) Ordinary gut: gut or bovine intestinal submucosa tissue production of easily absorbable suture. Absorption, slightly larger organizations gut reaction. Organization or subcutaneous tissue used for healing faster ligation of the blood vessels and suture infected wounds. Commonly used in the mucous layer of the uterus, bladder, etc..
(2) chromic catgut: This Department of catgut chromic acid treatment is made, can slow down the tissue absorption rate, it is caused by the inflammatory response less than ordinary catgut. Generally used for gynecological and urinary tract surgery, kidney and ureter surgery is often chosen suture thread will promote the formation of stones. Use in brine, to be softened straightened, so that the surgical procedure.
2 the chemical synthesis Line (PGA, the PGLA PLA): the use of existing chemical technology made of a linear polymer material, made of wire drawing, coating process, generally 60 ˉ 90 days absorption, absorption and stabilization, involving chemical composition, is still not fully absorbed.
Natural collagen sutures: based on the special animal the otter civet tendon parts, high levels of natural collagen production process involved in chemical composition, with collagen due; the true sense of the fourth substituting the suture. Has completely absorbed, high tensile strength, good biocompatibility, promote cell growth, and so on. According to the thickness of the line body usually 8-50 days completely absorbed, and the absorption is stable and reliable, no significant individual differences.
