Abstract
A method for closing an incision (I) deep within a patient's body (B) with a suture (S). A medical instrument (C) has arms 1 and 2 for openings and closing opposed jaws (3,4). Each jaw has a pair of openings (3A-3B, 4A-4B). A knot (K) is formed using the ends (S1, S2) of the suture. For this purpose, the ends of the suture are withdrawn from the body. This allows the surgeon to form a proper surgical knot. After forming the knot, the suture ends are inserted through the respective pairs of openings. The surgeon can now draw the knot tightly down on the incision to close it by inserting the jaws end of the instrument into the patient's body while applying a slight pulling force on the ends of the suture. The surgical knot thus made will not thereafter loosen.
