A surgical system includes an elongated assembly and an articulation joint defined in the elongated assembly. The elongated assembly articulates about the articulation joint. The articulation joint defines a central axis and a distal side portion. An offsetting member extends from the distal side portion of the articulation joint. An end effector is supported by the offsetting member. The end effector includes a blade and a jaw member movable relative to the blade between a spaced-apart position and an approximated position for clamping tissue. The offsetting member offsets the end effector with respect to the central axis of the articulation joint. An actuation cable extends through the central axis of the articulation joint. The actuation cable is operably coupled to the jaw member to pivot the jaw member with respect to the blade between the spaced-apart position and the approximated position.
