ABSTRACT:
A clip device for a living tissue in a body cavity includes an introducing tube insertable into the body cavity. An operating member of the device is advanceably and retreatably inserted into the introducing tube; the operating member has a distal end portion. An operating wire is advanceably and retreatably inserted into the operating member, and the operating wire has a distal end portion and a retainer attached to the distal end portion of the operating wire. The clip device further includes a clip having a proximal end portion and a pair of arm portions extending from the proximal end portion and provided with a tendency to open. A clip squeezing ring is removably attached to the distal end portion of the operating member for closing the arm portions of the clip by fitting to the arm portions of the clip. And a coupling member is insertable into the clip squeezing ring, and the coupling ring is removably engaged with the retainer. The coupling ring further includes a hook portion to be engaged with the proximal end portion of the clip; holding member holds the coupling member inside the clip squeezing ring such that the coupling member can be removed from the clip squeezing ring when the operating wire is retreated. At least one of the arm portions is bent inward so as to be bow-shaped, and has an inner side provided with friction increasing the structure for increasing friction between the inner side of the arm portion and the living tissue.
