ABSTRACT:
In a resectscope apparatus of the present invention, by using an output from a second output transformer, high frequency current passes through a treating electrode when the treating electrode is in contact with a living tissue in a conductive liquid. Then, the high frequency current flows between the treating electrode and a return electrode. Thus, the treating electrode generates heat. Bubbles are formed from the conductive liquid on the peripheral surface of the treating electrode and cover the treating electrode. Interlelectrode resistance increases from a resistance and becomes higher resistance to a substantially insulating state. Then, the voltage increases, and discharging occurs between the treating electrode and the living tissue. By using the high frequency current from the discharging, the living tissue is treated.
