ABSTRACT:
A medical instrument performs at least one of suture and ligation to form a suitable knot in a piece of suture within a body cavity. This medical instrument includes a suture having a first end portion, a second end portion, and at least one loop formed in advance at an intermediate portion between the first and second end portions to have a predetermined size, and a suture suitable for application to a body tissue, and a cylindrical body for holding the loop to almost maintain the size thereof. The body has a fastening portion for fastening at least one portion of the suture. The medical instrument further includes an inserting instrument which is to be inserted into the body cavity, which has a distal end portion that can be arranged in the body cavity, and an operating portion, arranged outside the body, for operating the distal end portion thereof, and on which a holding member having the suture wound thereon is mounted. The distal end portion of the inserting instrument projects beyond the loop held by the holding member, and has a gripping member capable of gripping the suture. This inserting instrument causes the first end portion of the suture gripped near an insertion port to the body cavity and in the body cavity to pass through the loop, thereby forming a knot.
