Abstract
A high-frequency incision instrument for an endoscope configured to project forward and retreat, through a forward end portion of a flexible over tube, a rod electrode disposed close thereto by remote operation from an operating unit connected to a proximal end portion of the over tube. The high-frequency incision instrument includes a fixed stopper and a movable stopper located close to a forward end portion of the over tube and to a proximal end portion of the rod electrode respectively, to be butted to each other to define a maximum projection length of the rod electrode from the forward end portion of the over tube. The movable stopper is axially movable with respect to the rod electrode, and the operating unit includes a stopper position adjuster that adjusts by remote operation a distance between a farthest end portion of the rod electrode and the movable stopper.
