Abstract:
1. An endoscopic instrument comprising: an incising section inserted into a body cavity endoscopically for carrying out incisional intervention; a wire having a distal end connected to the incising section; a sheath, made from insulative material, for allowing the wire to pass therethrough; a main body having a proximal end of the sheath fixed thereto; a wire-maneuvering section, having a proximal end of the wire fixed thereto, capable of freely sliding in an axial line direction of the main body; at least a stopper, provided to the incising section or the wire, for projecting radially outward relative to the wire; a distal-regulation section, provided to the sheath, for regulating proximal sliding movement of the wire by making contact with the stopper; and a proximal-regulating section, provided in the sheath, for regulating proximal sliding movement of the wire by making contact with the stopper, wherein different projection lengths of the incising section can be maintained when the stopper makes contact with the distal-regulation section and when the stopper makes contact with the proximal-regulating section.
