ABSTRACT:
According to the present invention, a high-frequency treatment apparatus includes: an electrode assembly electrically connected to the high-frequency generating unit for generating a high-frequency current, the assembly having at the distal end thereof a current-applying electrode for discharging the high-frequency current, the proximal end of the current-applying electrode being covered with a first insulating member; an insertion section receiving the electrode assembly such that the electrode assembly is movable in predetermined directions, the insertion section being located on the return side of the high-frequency current applied from the current-applying electrode; a liquid supply unit for supplying an irrigation liquid to the vicinity of the current-applying electrode; and a second insulating member for covering a predetermined area on the surface of base part of the current-applying electrode, the base part being exposed from the distal end of the first insulating member.
