A surgical tool for surgically treating tissue in a patient comprising a radio frequency power generator for creating an alternating current having an impedance matching circuit connected thereto for matching the impedance of a surgical instrument with the radio frequency generator. A loading and tuning coil is connected to a watts/ampere meter which is connected to the impedance matching circuit. The loading and tuning coil is connected to a surgical instrument which has a tip for focusing the radio frequency current at the region of the tissue such that the tissue being contacted is instantaneously vaporized and cut and/or cauterized.
