A forceps includes an end effector assembly having first and second jaw members, each including a proximal flange and a distal jaw body defining a tissue-treating surface. The second jaw member is both proximally offset and spaced-apart from the first jaw member. One or more resilient bands extends between and interconnects the proximal flanges of the jaw members. The resilient band(s) is configured to bias the first and second jaw members towards an open position. The resilient band(s) is configured to flex in response to distal translation of the second jaw member relative to the first jaw member to thereby move the second jaw member relative to the first jaw member to a closed position for grasping tissue between the tissue-treating surfaces thereof. In the closed position, the second jaw member is disposed in an aligned orientation and is approximated relative to the first jaw member.
