Abstract: PURPOSE: To provide an electric surgical device used for coagulating or cutting a tissue having less electricity leakage. CONSTITUTION: The device is equipped with an electrically insulated housing, a hand operated electric surgical pencil with an electrode that has an end part forming a top, a supplying means that supplies high-frequency alternating current energy from a generator to tissue through an electrode, a complete circuit that transmits the electric energy back to the generator, and switches 3, 4, 5, 6, that select cut mode or coagulation mode installed in a housing lock. The switches connect the generator with a low voltage direct current circuit that provides the control signals to the cut mode or the coagulation mode. Therefore, an expectant high-frequency alternating energy is supplied from the current generator to the electrode, and the current leakage is restrained.
