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 size as well as thread material ...
The horizontal mattress stitch is a suture technique used to close wounds.It everts skin well and spreads tension along the wound edge. [1] [2] [3] This makes it ideal for holding together fragile skin [4] as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs.
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 ...
Stronger braided suturing thread is preferred because the knot has a tendency to fray as it is slid down the cannula. At the end of the running suture line, clips can be placed across the suture tail. Barbed suture is a knotless surgical suture that has a pattern of barbs on its surface. These barbs lock the suture into the tissue, eliminating ...
They tend to absorb this suture at a higher rate. Special precautions should be taken in elderly patients and patients with history of anemia and malnutrition conditions. As with any suture material, adequate knot security requires the accepted surgical technique of flat and square ties. The PDS suture knots must be properly placed to be secure.
In a less obtrusive way, a trocar button can be used in place of a suture. It is attached to a suction hose, usually attached to a water aspirator , but an electric aspirator can also be used. The process of removing gas, fluids, and semi-solids from the body cavities and hollow organs using the trocar is known as aspiration.
In some types of fistulae, a seton may be tied with more tension and tightened periodically. In this case, the seton loop will slowly cut through tissue inside the loop while scarring behind the loop, essentially "pulling out" the fistula without surgery. This is the Kshar-Sutra method mentioned by Sushruta in ancient Indian surgical practice.
A standard general surgical needle holder, with a ratchet handle lock. Two specialty needle holders, Mathieu needle holder (above) and Castroviejo needle holder (below). A needle holder, also called needle driver or needle forceps, is a surgical instrument similar to a hemostat, used by doctors and surgeons to hold and push a suturing needle when performing wound closure, ligation and other ...
