ABSTRACT:
An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness, compressibility, density, vascularity, etc., especially in the performance of endoscopic procedures. The instrument provides two electrodes of different electrical potentials. One electrode is moveable with respect to the other electrode to vary the distances between the electrodes and thus the impedance of the tissue as presented to the generator. The electrode distances may be varied by an automated or user controlled device.
