A surgical knot is a type of knot used in medical procedures to securely tie sutures or ligatures. It is designed to hold tissues together during healing and prevent bleeding. Surgical knots are crucial in various surgeries, ensuring that the stitches remain tight and do not come undone. There are different techniques for tying surgical knots, including the square knot and the slip knot. Surgeons often use specific methods to achieve the desired tension and security, depending on the tissue type and surgical procedure. Proper knot tying is essential for successful surgical outcomes and patient recovery.
