Patent ID: 7223271

Claim:
A ligating apparatus comprising: an introducing tube which is inserted in a living body cavity; a manipulating wire inserted through the introducing tube in such a manner that the manipulating wire is movable in advancing and retreating directions; a clip having a base end and at least two arm portions extending from the base end, each of the arm portions having a holding portion apart from the base end, and the base end having a through hole which is extended in the advancing direction and through which said manipulating wire is inserted, the manipulating wire including a tip end which is projected from the through hole and positioned between the arm portions; and a stopper having a bulged portion formed at the tip end of the manipulating wire, the bulged portion having a larger diameter or width than that of the through hole so that the bulged portion engages with the base end; wherein the base end and/or bulged portion is deformed when the manipulating wire is moved in the retreating direction against the base end of the clip, so that the diameter or width of the bulged portion becomes relatively smaller than that of the through hole and is disengaged with the base end whereby the tip end of the manipulating wire is removed from the base end through the through hole.
