Surgical suture on needle holders. 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.
The following table compares some of the most common adsorbable sutures. Plain catgut. Chromic catgut. Polyglycolide. (P.G.A.) Polydioxanone (PDS) Description. Adsorbable biological suture material. Plain is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines.
shown above. [edit on Wikidata] A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and ...
Non-absorbables are frequently used inside the body when long-term strength is needed, particularly in cardiovascular surgery. E.g. replacing a peice of aorta or implanting coronary bypasses. Absorbable sutures do have a controlled time period of dissolution - different materials take different time to break down. E.g. chromic gut takes 7-14 days.
Projectional radiograph of surgical staples. Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or connect or remove parts of the bowels or lungs. The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close. [1]
Polyglycolide or poly (glycolic acid) (PGA), also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. PGA has been known since 1954 as a tough fiber -forming polymer.
Prolene is a brand of synthetic polypropylene used in monofilament nonabsorbable sutures and meshes. The suture is indicated for skin closure and general soft tissue approximation and ligation. Its advantages include minimal tissue reactivity and durability. Disadvantages include fragility, high plasticity, high expense, and difficulty of use ...
Biodegradable polymers have a long history, and since many are natural products, the precise timeline of their discovery and use cannot be accurately traced. One of the first medicinal uses of a biodegradable polymer was the catgut suture , which dates back to at least 100 AD. [ 4 ]
