Abstract: An end effector assembly is provided. The end effector assembly includes a pair of first and second jaw members including respective seal plates adapted to connect to a source of electrosurgical energy. The first and second jaw members operable in a first bipolar mode of operation for treating tissue and a second bipolar mode of operation for separating tissue. A dissector translatable through one of the first and second jaw members is in electrical communication with one of the seal plates of the first and second jaw members and activatable in the second bipolar mode of operation for separating tissue when the first and second jaw members are in one of the open and clamping position and tissue is adjacent thereto.
