A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members. One or more drive surfaces are disposed on the actuating mechanism and configured to compress a spring upon movement of the actuating mechanism to the actuated position. The spring imparts a spring force in a distal direction to bias the actuating mechanism to the unactuated position. An electrically conductive tissue sealing surface extends along a length of one or both of the jaw members and is adapted to connect to a source of electrosurgical energy.
