Surgical suture

Short Description:

Surgical suture is a medical device used to hold body tissues together after an injury or surgery. Application generally involves using a needle with an attached length of thread. A number of different shapes, sizes, and thread materials have been developed over its millennia of history. Surgeons, physicians, dentists, podiatrists, eye doctors, registered nurses and other trained nursing personnel, medics, clinical pharmacists and veterinarians typically engage in suturing. Surgical knots are used to secure the sutures

Suture thread is made from numerous materials. The original sutures were made from biological materials, such as catgut suture and silk. These absorbed bodily fluids and could be foci of infection. Founder of gynecology J. Marion Sims invented the use of silver wire, which is anti-bacterial, for a suture. Most modern sutures are synthetic, including the absorbables polyglycolic acid, polylactic acid, Monocryl and polydioxanone as well as the non-absorbables nylon, polyester, PVDF and polypropylene.[2] The FDA first approved triclosan-coated sutures in 2002;[3] they have been shown to reduce the chances of wound infection.[4] Sutures come in very specific sizes and may be either absorbable (naturally biodegradable in the body) or non-absorbable. Sutures must be strong enough to hold tissue securely but flexible enough to be knotted. They must be hypoallergenic and avoid the “wick effect” that would allow fluids and thus infection to penetrate the body along the suture tract.




Sutures are placed by mounting a needle with attached suture into a needle holder. The needle point is pressed into the flesh, advanced along the trajectory of the needle’s curve until it emerges, and pulled through. The trailing thread is then tied into a knot, usually a square knot or surgeon’s knot. Ideally, sutures bring together the wound edges, without causing indenting or blanching of the skin,[17] since the blood supply may be impeded and thus increase infection and scarring.[18][19] Ideally, sutured skin rolls slightly outward from the wound (eversion), and the depth and width of the sutured flesh is roughly equal.[18] Placement varies based on the location,
