( Surgical staple)
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds, connect or remove parts of the bowels or lungs. A more recent development, from the 1990s, uses clips instead of staples for some applications; this does not require the staple to penetrate. Stapling is much faster than suturing by hand, and also more accurate and consistent. In bowel and lung surgery, staples are primarily used because staple lines are less likely to leak blood, air or bowel contents. In skin closure, dermal adhesives (skin glues) are also an increasingly common alternative. The technique of stapling for surgery is said to have been influenced by the Roman use of ants for wound closure. Staplers were originally developed to address the perceived problem of patency (security against leaks of blood or bowel contents) in anastomoses in particular. Leaks from poor suturing of bowel anastomoses was at that time a significant cause of post-surgical mortality. More recent studies have shown that with current suturing techniques there is no significant difference in outcome between hand sutured and mechanical anastomoses, but mechanical anastomoses are significantly quicker to perform.[1]
