A forceps includes a shaft defining first opposed distal recesses, a drive bar slidably disposed within the shaft and defining second opposed distal recesses, and an end effector assembly including first and second jaw members. Each jaw member defines a proximal flange and a distal jaw body. The proximal flanges each define an aperture and a cam slot. A pivot pin extends through the apertures with ends of the pivot pin extending outwardly from the jaw members to be at least partially disposed within the first recesses and fixedly engaged therewith. A drive pin extends through the cam slots with ends of the drive pin extending outwardly from the jaw members to be at least partially disposed within the second recesses and fixedly engaged therewith such that translation of the drive bar relative to the end effector assembly pivots the jaw members between spaced-apart and approximated positions.
