Claim 17:
18. A shaft assembly configured for attachment to a robotic arm, the shaft assembly comprising:
a proximal segment;
a clevis including:
an elongated outer body defining a longitudinally-extending central channel therethrough configured for passage of a plurality of actuation components;
a first wall projecting from the elongated outer body into the central channel, the first wall defining a longitudinally-extending first passageway configured for slidable receipt of at least one of a knife rod or a knife blade; and
a second inner wall projecting from the elongated outer body into the central channel, the second inner wall defining a pair of longitudinally-extending second and third passageways configured for receipt of first and second electric wires;

a distal segment rotationally fixed to the clevis and having a nub keyed to a slot defined in the elongated outer body of the clevis; and
an articulating link pivotably coupled to and interconnecting the proximal segment and the distal segment, the articulating link including a pair of spaced-apart pivot flags,
wherein the distal segment is articulatable with the clevis relative to the proximal segment, and wherein the distal segment defines a pair of depressions configured to receive the corresponding pair of spaced-apart pivot flags of the articulating link in longitudinal alignment with the nub.
