ABSTRACT:
A ligation apparatus includes an insertion tube extending toward one direction, a clamp part which is provided on a distal side of the insertion tube and clamps a living organ, a first control mechanism which is connected to the clamp part via a first control shaft member inserted inside the insertion tube and controls opening-and-closing action of the clamp part by advancing and retracting the first control shaft member, a ligation part which ligates the living organ by closing a pair of arm members provided on the distal side of the insertion tube; and a second control mechanism which is connected to the ligation part via a second control shaft member inserted inside the insertion tube, and closes the pair of arm members and releases the ligation part by advancing and retracting the second control shaft member.
