A forceps includes an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaws is moveable with respect to the other between a spaced-apart position and at least one approximated position for grasping tissue therebetween. At least one of the jaw members is adapted to connect to a source of energy for sealing tissue disposed between the jaw members. A chamber is defined within and extends longitudinally along at least one of the jaw members. The chamber is configured to retain a fluid therein and includes a series of apertures disposed on a tissue-facing surface thereof such that, upon application of energy to the jaw member(s), fluid within the chamber is heated to thermally expand within the chamber and forcefully exit the apertures to divide tissue disposed between the jaw members.
