Absorbable surgical sutures
Chromic catgut and Plain catgut
Surgical suture ( Plain and Chromic ) is an absorbable sterile surgical suture composed of purifled connective tissue ( mostly collagen ) derived from either the serosal layer of beef ( bovine ) or the submucosal fibrous layer of sheep ( ovine ) intestines. The chromic gut contains a chromic salt solution to delay absorption . Surgical gut suture meets all requirements established by the United States Pharmacopeia( U.S.P.) for absorbable surgical sutures .
The main peformance
1. cell adhession is strong , has good biocompatibility , non-toxic side effects absorption of stable
2. threads body have antibacterial actuvity , can inhibit bacterial growth of the wound site, and induces wound tissue growth ,wound healing .
3. surface of the body is made through a special process, it's smooth , easy to suture.                                                                             .
4. high tensile strength , soft body , easy to knot is very stable .
5. easy to store and transport , can application to all types of wound sew
