A forceps is provided. The forceps includes a housing having a shaft that extends therefrom. The bipolar forceps also includes a hydraulic mechanism that includes a fluid line and a plunger operatively coupled to the fluid line. The plunger is translatable within at least a portion of the shaft from a proximal position to a distal position. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members biased in an open configuration. Each of the first and second jaw members configured to receive at least a portion of the plunger when a fluid is caused to flow within the fluid line such that the first and second jaw members move from an open position for positioning to a closed position for grasping tissue.
