Claim:
A ligature and suture device for medical application that ligatures or sutures biomedical tissue that has been suctioned by a suction device using a suturing member, the ligature and suture device comprising: an insertion portion having a lumen into which an endoscope can be inserted, and a distal end portion that is connected to the lumen and in which at least one side aperture is provided; at least one hollow needle that is able to support inside itself the suturing member, and that is placed inside the insertion portion such that a tip of the hollow needle is able to move between a first position, which is on a base end side of the side aperture, and a second position, which is on a distal end side of the side aperture; an operating section that performs an operation to move the needle; and at least one pledget that can be penetrated by the needle, and that is placed in the distal end portion and closer to a tip of the distal end portion than the side aperture, so as to be freely removable from the distal end portion, the pledget has a semicircular shape, having a circular arc portion, and wherein the suturing member includes a string member and a holding member being provided at a distal end of the string member and holds the pledget against the biomedical tissue, wherein a slit into which the pledget can be press-inserted is provided so as to open onto a side surface of the distal end portion between the side aperture and the second position, and wherein, the pledget and the slit of the distal end portion are configured so that, when the pledget is press-inserted into the slit, the circular arc portion of the pledget is held by the distal end portion at the slit.
