Catgut suture

Common card · No. 480438

Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes. Full tensile strength remains for at least 7 days, and absorption is complete by 90 days. This eventual disintegration makes it good for use in rapidly healing tissues and in internal structures that cannot be re-accessed for suture removal. Catgut suture has excellent handling features, high knot-pull tensile strength, and good knot security. It is used for all surgical procedures including general closure, ophthalmic, orthopedics, obstetrics/gynecology and gastrointestinal surgery. It is absorbed faster in patients with cancer, anemia, and malnutrition. It also absorbed faster when used in the mouth and the vagina, due to the presence of microorganisms. Catgut has largely been replaced in non-absorbable applications, first by silk, then various synthetic materials...
