<p>A bipolar electrosurgical instrument having a pair of relatively moveable jaws (22, 24), each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced apart electrodes (42, 44, 46, 48) that are adapted for connection to a bipolar RF generator (12). The first and second electrodes of one jaw are in offset opposed relation, respectively, with the first and second electrodes of the other jaw. The tissue contacting surfaces are disposed between the electrodes on each jaw, and the first opposed electrodes of each jaw are connectable to one terminal of the RF generator, while the second opposed electrodes of each jaw are connectable to the other terminal of the generator. A cutting portion is provided which moves to provide the device with a scissors-like capability or a grasper like capability.</p> |
