1. A surgical instrument comprising:
a handle;
an articulation cam that is movable relative to the handle between at least a first position and a second position, the articulation cam including a first cam profile and a second cam profile, wherein the articulation cam is rotationally movable relative about a rotation axis of the articulation cam to move the articulation cam from the first position to the second position, wherein the first cam profile and the second cam profile are arranged on opposing sides of the rotation axis of the articulation cam; and
an elongated shaft assembly extending distally from the handle, the elongated shaft assembly comprising:
a first shaft including a proximal portion coupled to the first cam profile; and
a second shaft including a proximal portion coupled to the second cam profile, the second shaft coaxially arranged relative to the first shaft,
wherein moving the articulation cam from the first position to the second position radially displaces the proximal portion of the first shaft and the proximal portion of the second shaft relative to the rotation axis of the articulation cam.
