Surgical sutures are medical devices used to close wounds or surgical incisions. They are made from various materials, including silk, nylon, and absorbable polymers, which dissolve over time. Sutures help promote healing by holding tissue together and preventing infection. There are different types of sutures, such as interrupted and continuous, each serving specific purposes in surgery. The choice of suture depends on factors like the type of tissue being stitched and the desired healing time. Proper suture technique is essential for minimizing scarring and ensuring optimal recovery.
