Summary:A surgical instrument includes a housing, a shaft extending from the housing and having proximal and distal segments, a ball and socket joint interconnecting the proximal and distal segments, and an end effector assembly supported at the distal segment. An outer tube surrounds the shaft, may be operably coupled to the end effector assembly, and may be rotatable around the shaft to rotate the end effector assembly about a longitudinal axis defined by the shaft. First, second, and third cables extend about the ball and socket joint. A distal end of the first cable, a distal end of the second cable, and a distal end of the third cable may be equally spaced around an outer surface of a socket of the ball and socket joint. Longitudinal translation of at least one of the first, second, or third cables causes the end effector assembly to articulate relative to the longitudinal axis.
