ABSTRACT:
A bipolar electrosurgical instrument having a pair of relatively moveable jaws, 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 that are adapted for connection to the opposite terminals of a bipolar RF generator so as to generator a current flow therebetween. The first and second electrodes of one jaw are in 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 bipolar RF generator, while the second opposed electrodes of each jaw are connectable to the other terminal of the bipolar RF generator.
