ABSTRACT:
An endoscopic instrument includes: a knife; a wire having a distal end connected to the knife; a sheath around the wire; a main body having the freely rotative sheath fixed thereto; a slider fixed to the wire, slidable in an axial direction of the main body; a stopper projecting radially from the wire; a first-distal-regulation section in the sheath for regulating distal sliding movement of the wire by making contact with the stopper; and a second-distal-regulation section, provided distal to the first-distal-regulation section, for regulating sliding movement of the wire by making contact with the stopper, wherein the stopper is capable of moving between the first-distal-regulation section and the second-distal-regulation section by rotating the main body relative to the sheath around an axial line by predetermined angle, and at least two different projection lengths can be maintained by contacting the main body to the first-distal-regulation section or the second-distal-regulation section.
