Abstract
A high-frequency incision instrument for an endoscope is provided with a flexible sheath, and a rod electrode remotely operated to protrude from/retract into the distal end portion of the sheath. A stationary stopper provided at the distal end portion of the sheath and a movable stopper provided at the proximal end portion of the rod electrode, the movable stopper contacting the stationary stopper to define a maximum protruding amount of the rod electrode from the distal end of the sheath. A proximal end portion of the rod electrode is screw-engaged with a member to which the movable stopper is formed, and the rod electrode is rotatable so that screw-engaged amount of the proximal end portion of the rod electrode with respect to the member is changed, thereby a distance between the tip end of the rod electrode and the movable stopper being adjustable.
