Title: ELECTRODE FOR USE IN A BIPOLAR ELECTROSURGICAL INSTRUMENT
Abstract:
A end-effector assembly includes opposing first and second jaw assemblies, at least one of the first and second assemblies movable relative to the other from a first position wherein the jaw assemblies are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the jaw assemblies cooperate to grasp tissue therebetween. The first jaw assembly includes a first housing and a first electrically-conductive tissue-engaging structure associated with at least a portion of the first housing. The second jaw assembly includes a second housing and a second electrically-conductive tissue-engaging structure associated with at least a portion of the second housing. The end-effector assembly includes a dissector electrode coupled along at least a portion of a lateral side portion of either one of the first housing or the second housing. The dissector electrode is electrically-isolated from the first and second electrically-conductive tissue-engaging structures.
