A surgical suture is a medical device used to close wounds or surgical incisions. Made from various materials, such as silk, nylon, or absorbable polymers, sutures help promote healing by holding tissue together. They come in different sizes and types, including interrupted and continuous sutures, depending on the specific needs of the procedure. Sutures can be classified as either absorbable or non-absorbable. Absorbable sutures dissolve over time and do not require removal, while non-absorbable sutures must be taken out after the healing process. Proper suture technique is essential for minimizing scarring and preventing infection.
