Abstract:
1. A ligature and suture device for medical application, comprising: a puncture handle that is connected via a flexible sheath to a needle body that inserts a ligature member through biomedical tissue; a pressing handle that is connected to a pressing member that is inserted into the needle body in order to press a holding member that is attached to an end portion of the ligature member; a ligature tool operation unit that is connected to a ligature sheath that presses a stopper that is penetrated by the ligature member; a housing in which are fitted the puncture handle, the pressing handle, and the ligature tool operation unit such that each moves freely backwards and forwards; a first linking device that moves the puncture handle and the pressing handle forward interconnectedly from an initial position where the puncture handle is moved back as far as possible to a tissue puncture position where the puncture handle has moved forward as far as possible and has punctured the biomedical tissue, and releases the link between the puncture handle and the pressing handle at the tissue puncture position; and a second linking device that engages the ligature tool operation unit with the pressing handle until the tissue puncture position is reached, and moves the ligature tool operation unit forward in conjunction with the pressing handle.
