ABSTRACT:
A surgical scissors instrument having disposed at its distal end two bipolar electrode structures which function to coagulate tissue immediately prior to its being severed by scissor action. The instrument comprises a first scissors blade having a distal end and a second scissors blade having a distal end, wherein at least one of the blades is pivotable in relation to the other blade. A first electrically insulated bipolar electrode structure is disposed longitudinally distally from the distal end of the first scissors blade, and a second electrically insulated bipolar electrode structure is disposed longitudinally distally from the distal end of the second scissors blade. The instrument thereby permits a physician to precisely apply electrical energy only at the distal end of the scissor's blades, and to thereafter immediately cut coagulated tissue situated immediately forward of the blade members.
