<p>The endoscope treatment tool consists of a movable distal end portion 5 that performs treatment on a living body; a plurality of first coil sheaths 6A, 6B that consist of a single element wire 6a being spirally wound; a second coil sheath 7 that consists of a plurality of element wires 7a being spirally wound in the same direction and is externally mounted on the first coil sheaths 6A, 6B; a plurality of operating wires 8 that are shaped to extend in a long and thin manner with the distal ends thereof connected to the movable distal end portion 5; and an operating portion that performs the extending and retracting operation of the operating wires 8, in which the distal end of the second coil sheath 7 being fixed to the movable distal end portion 5 and the base end thereof being fixed to the operating portion, and the operating wires 8 being arranged by being passed in a movable manner through the respective first coil sheaths 6A, 6B. In accordance with the present invention, it is possible to provide an endoscope treatment tool that can increase both the rotation operability and movability of the movable distal end portion and enable a simplification of procedures.</p> |
