first and second jaw members, at least one of the first or second jaw members movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween, the first jaw member including:
a structural frame including a body having first and second body segments spaced-apart relative to one another;
an energizable cutting element disposed between and spaced-apart from each of the first and second body segments of the body of the structural frame, the energizable cutting element including a distal end in contact with and supported by a distal tip of the body of the structural frame;
a tissue-treating plate disposed over the structural frame, the tissue-treating plate defining a channel, wherein the energizable cutting element extends at least partially through the channel; and
