Apparatus for ligating living tissues

摘要

The present invention has an introducing tube capable of being inserted into a living body cavity, a manipulating wire movably inserted into this introducing tube, at least two or more clips, and a ligating wire causing the clip and the manipulating wire to be engaged with each other wherein, when the clip is ligated, a tensile stress of the manipulating wire is always applied only to the clip located at the most distal end.

主权项

1. An apparatus for ligating living tissues comprising:
a flexible introducing tube having a distal end and capable of being inserted into a living tissue; a flexible manipulating wire movably inserted into said introducing tube; a plurality of clips including one clip located on the most distal end side, the plurality of clips being disposed in series in said introducing tube, each of the plurality of clips having a proximal end portion, arm sections extending from the proximal end portion and pinch sections formed at a distal end portion of the arm sections, each of the plurality of clips having an opening/expanding property; a mechanism which, when said one clip is protruded from the distal end of said introducing tube by forwardly moving the plurality of clips, prevents the clip or clips other than said one clip from being protruded from the introducing tube, wherein said one clip protruded from the distal end of the introducing tube is closed by backwardly pulling the flexible manipulating wire.
