a second jaw member;
a clamping member slidably positioned to translate at least partially through the first jaw member, the clamping member engaging the first jaw member and the second jaw member, and having a knife blade for cutting tissue;
the second jaw member including a cam surface on an outer surface of the second jaw member, wherein a flange of the clamping member is configured to engage the cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position; and
a clamp apparatus movable from a retracted position to an advanced position where the clamp apparatus contacts proximal portions of the first jaw member and the second jaw member for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance;
