Abstract

Surgical devices, systems, and methods are provided for applying monopolar energy and bipolar energy to tissue. In one embodiment, a surgical device is provided with an end effector that has first and second jaws movable between an open position and a closed position, and a conductive member that extends through the end effector. The conductive member has a retracted position in which the conductive member is substantially disposed within the end effector and an extended position in which the conductive member extends at least partially distally beyond the end effector. The conductive member is configured to conduct energy through tissue adjacent thereto at least when the conductive member is in the extended position.
