Abstract: A treatment device includes a flexible sheath; a wire configured to be inserted into the sheath; a first treatment member disposed at distal side from the wire; a second treatment member disposed at a distal side from the first treatment member; and a protection member configured to cover the second treatment member when the first treatment member projects from a distal end of the sheath.

Abstract: A treatment device includes a flexible sheath; a control wire that can move axially within the flexible sheath; a first treatment member connected to a distal end of the control wire; a second treatment member connected to a distal end of the first treatment member; and a protection member that covers the second treatment member depending on the mode of operation. When the treatment device is in a first treatment mode, the second treatment member projects from a distal end of the protection member. When the treatment device is in a second treatment mode, the first treatment member projects from the distal end of the flexible sheath, and the protection member covers the second treatment member.

Abstract: An endoscope treatment tool includes a sheath having electric insulation; and an electrode unit provided at a distal end portion of the sheath. The electrode unit includes a rod-shaped electrode that is provided to extend in an axis direction of the sheath and is capable of being arranged in a state where the electrode protrudes from the distal end portion of the sheath and is exposed to the outside; and a chip that is fixed in a state where a distal end portion of the electrode is inserted into a concave portion provided in a proximal end surface so as to extend in the axis direction, has a greater external diameter than the external diameter of the electrode, and is formed from a single electric insulation material. The concave portion is formed with a smaller-diameter portion that allows the distal end portion of the electrode to be inserted thereinto.
