Equipment required for suture closure of a wound includes the following:

Suture material is a foreign body implanted into human tissues; consequently, it elicits a foreign-body tissue reaction. During wound closure, a sterile field and meticulous aseptic technique are critical to minimize the risk of wound infection. Other complications of wound healing, such as hypertrophic scars, wide scars, and wound dehiscence, may result from patient factors (eg, nutritional status), incorrect suture selection, or a technique that results in excessive tension across the wound.

Surgical needles are produced from stainless steel alloys, which have excellent resistance to corrosion. [28] All true stainless steels contain a minimum of 12% chromium, which allows a thin, protective surface layer of chromium oxide to form when the steel is exposed oxygen. Since their development ...
