ABSTRACT:
A high efficiency electrosurgical ablator which is subjected to a fast and slight oscillatory motion during resection of tissue. The electrosurgical ablator is positioned in the proximity of the tissue to be treated in the presence of an electrically conductive fluid. A high frequency voltage is applied to the electrode of the ablator, and the ablator is subjected to a vibratory motion created by, for example, a mechanical or electromechanical oscillator or a piezoelectric element. The vibratory motion permits more tissue to become available in the destructive, sparking zone, thereby increasing the efficiency of operation.
