LIGATION DEVICE

摘要

A ligation device for ligating a living tissue by a clip, where the ligation deviceis optimal for ligation of a living tissue in a body cavity. The ligation device has a clip (26) opened and closed when a clip claw member (42) is advanced and receded relative to a pressing member (40); a sheath (28) capable of receiving the clip (26) such that the clip claw member (42) is not exposed to the outside; an advancement/recession restriction mechanism (50, 52, 54, 56) for restricting, at the head of the sheath (28), the advancement and recession, relative to the sheath (28), of a pressing member (40) to enable the clip (26) to ligate a living tissue, enabling the advancement and recession, relative to the pressing member (40), of the clip claw member (42) by the advancement and recession of an operation wire (30) relative to the sheath (28); and a release mechanism (66, 74, 76, 78) for releasing at least a part of the clip (26) from the sheath (28) with the living tissue ligated.
