1. An electrosurgical tissue sealing device, comprising:
a housing;
a shaft extending from the housing and defining a longitudinal axis;
first and second jaw members coupled to a distal end portion of the shaft and movable between an open position and a clamping position, each of the first and second jaw members defining a cam slot;
a drive assembly including two cables, the drive assembly extending from within the housing through the shaft, the two cables configured to move longitudinally within the shaft to impart movement of the first and second jaw members;
a center link coupled to a respective distal end of the two cables; and
a pair of cam pins extending from the center link and disposed within the respective cam slots of the first and second jaw members, wherein longitudinal movement of the two cables within the shaft causes the pair of cam pins to translate within the respective cam slots to move the first and second jaw members between the open and clamping positions.
