    Abstract: An endoscope treatment tool includes a flexible sheath, a manipulation wire, and a basket portion constituted by a locking portion and a plurality of elastic wires. A maximum outside diameter portion of the basket portion is at a position closer to the locking portion than an intermediate position between a proximal end of the basket portion and the locking portion. The plurality of elastic wires is formed in a shape of a helix, and a winding pitch of the plurality of elastic wires becomes gradually smaller in a direction from a proximal side to the distal side of the manipulation wire. When a proximal side of the basket portion is reduced, an outside diameter of the maximum outside diameter portion is maintained at substantially a same size as the outside diameter before the proximal side of the basket portion is reduced.

    Abstract: A treatment tool for an endoscope includes a sheath which is extended along a longitudinal axis; a pre-curved portion which is disposed at a distal portion of the sheath; a knife wire lumen which is formed along the longitudinal axis of the sheath; a first communication hole and a second communication hole which are open on an outer circumferential surface to communicate the outer circumferential surface positioned with the knife wire lumen; a wire-shaped cutting portion which is protruded from the first communication hole and the second communication hole, and is extended in a position spaced from the outer circumferential surface and the virtual plane; a fixing portion which is provided to fix an end portion of a wire connected to the cutting portion inside the knife wire lumen, and a bending portion which is provided to bend the wire.
