A forceps includes an end effector assembly having first and second jaw members disposed in parallel orientation relative to one another. One or both of the jaw members is movable along a first axis relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween. The first and second jaw members are configured to maintain the parallel orientation therebetween upon movement of the jaw members between the spaced-apart and approximated positions. A drive bar is coupled to one or both of the jaw members. The drive bar is selectively movable along a second axis that is different from the first axis between first and second positions for moving the jaw members between the spaced-apart and approximated positions.
