A forceps includes an end effector assembly having first and second jaw members each defining a proximal portion, a distal portion, and an intermediate portion. The distal portions define tissue-treating surfaces and the intermediate portions are disposed in overlapping relation relative to one another. A shaft is configured to receive the proximal portions and includes a retention feature for operably retaining the first and second jaw members at the distal end of the shaft. A drive bar is disposed within the shaft and operably associated with the proximal portions such that translation of the drive bar through the shaft and relative to the end effector assembly moves the first and second jaw members between a spaced-apart position and an approximated position for grasping tissue between the tissue-treating surfaces thereof.
