Abstract
A knot forming instrument forms a knot of a thread inside an abdominal cavity of a patient. This instrument includes an control rod to be inserted into a communicating tube which communicates the abdominal cavity and the outside of a body of the patient, an insertion path formed inside the control rod and having an opening formed at a tip portion of the control rod; thread introducing mechanism for introducing the thread into the insertion path from the opening; and a control device formed on the base portion for operating the control rod from the outside of the body. The tip portion of the control rod constitutes a bendable portion which can be deformed between a straight condition and a bent condition bent into a loop shape by the operation of the control device. In a preferred method, one end of the thread is held by the control rod and the tip portion thereof is bent so as to form the loop. Thereafter, the other end of the thread is inserted into the loop with another control rod to twist the ends of the thread, and a tension is applied to the thread to form a knot.
