)項記載の高周波処置具。[Claims for Utility Model Registration] (1) A closure in which a pair of conductive cups are disposed at the tip of an electrically insulating sheath, and the edge blades of both cups are joined. A high-frequency treatment instrument that is opened and closed from the position to an open position in which the edge blade portions of both cups are separated, and treatment electrodes for resection are formed on both the cups by a high-frequency current applied to both the cups. In,
A high-frequency treatment instrument characterized in that an insulating portion coated with an insulating material is formed on the portions of both the cups other than the tip portions thereof, and local treatment electrodes are formed on the tip portions of the both cups. (2) The high-frequency treatment instrument according to claim (1) of the utility model registration, characterized in that the local treatment electrode is formed only on each joining edge blade of both cups at the tip of the cup. (3) A practical application characterized in that the insulating part is formed on the entire conductive exposed surface of the sheath tip, excluding the local treatment electrode formed on each joining edge blade of both cups at the tip of the cup. Scope of Claim for New Patent Registration No. 2
) The high-frequency treatment device described in item ).
