Abstract
An endoscopic instrument includes: a high-frequency knife for carrying out incisional intervention; a wire having a distal end connected to the high-frequency knife; an outer sheath for allowing the wire to pass therethrough; a main body having a proximal end of the sheath fixed thereto; a first slider, capable of freely sliding on the main body, having the wire fixed thereto; at least a stopper projecting radially outward relative to the wire; a first abutment member making contact with the stopper and regulating distal sliding movement of the wire; and a projection-length-adjusting member, provided in the outer sheath, for regulating proximal sliding movement of the wire by making contact with the stopper. This configuration allows the high-frequency knife to be maintained at different projection lengths based on the stopper making contact with the first abutment member and the stopper making contact with the projection-length-adjusting member.
