Abstract
A surgical instrument having a housing, an outer shaft extending from the housing along a longitudinal axis, an inner shaft extending within the outer shaft along the longitudinal axis, a rotator knob position about the outer shaft, and a tube stop coupling the rotator knob to the outer shaft for collective rotation about the longitudinal axis and fixed within the housing against movement along the longitudinal axis. The tube stop has a pair of bearing surfaces that extend into a pair of longitudinal tracks of the outer shaft, and the rotator knob includes a pair of rails that extend into the pair of tracks of the outer shaft and block the tube stop exiting the tracks. The tube stop is captured between a pair of ribs in the housing to hold the tube stop in place while allowing the rotator knob to rotate the outer shaft.
