摘要： An endoscopic treatment device includes a sheath formed from a resin; a flow-passage formation member attached to a distal end portion of the sheath to be rotatable around a longitudinal axis of the sheath; a pair of forceps pieces supported by the flow-passage formation member such that the pair of forceps pieces are able to be opened and closed; a link mechanism connected to the pair of forceps pieces and configured to open and close the pair of forceps pieces; an operation wire extending along the longitudinal axis of the sheath; and a connection member configured to connect a proximal end arm of the link mechanism and the operation wire.

摘要： An endoscopic treatment may include a sheath extending in a longitudinal direction, a distal end member having insulation and the distal end member provided at a distal end of the sheath and having a through-hole penetrating in the longitudinal direction. The treatment tool may further include an electrode having a first conduit extending in the longitudinal direction and the electrode being configured to advance and retract into the through-hole. The electrode including a rod extending in the longitudinal direction and configured to be arranged in at least a part of the first conduit.

摘要： A treatment instrument includes a tube with a conduit; a wire located in the tube so as to advance and retract in the tube, and through which a high frequency current is allowed to flow. The treatment instrument may also include an electrode connected to a distal end of the wire; and a distal end tip located at a distal end portion of the tube, the distal end tip configured to accommodate at least a part of the electrode. The distal end tip includes a passage that connects with an outer peripheral surface and an inner peripheral surface of the distal end tip. The passage connects with the conduit.
