Claims

[Scope of utility model registration request]

an introduction tube inserted into a living body cavity, an operating member inserted into the introduction tube so as to be freely advanced and retractable, an operation wire that is inserted into the introduction tube and provided with a hook at its tip and capable of moving forward and backward with respect to the operation member; A clip tightening ring is detachably attached to the operating member, and a clip tightening ring is detachably attached to the hook and is normally biased to the open state, thereby opening the opening in the introduction tube in the axial direction of the introduction tube. The present invention is characterized by comprising a clip that is stored sideways along the guide tube and is closed by being pulled out from the tip of the introduction tube, pulling the operating wire toward the user's hand, and pulling it into the clip tightening ring. A device for clipping living tissue.
