Abstract
A powered stapling device includes an adapter assembly that includes an outer tube, a shifter mechanism, an articulation gear, and a rotate gear. The rotate gear is secured to the outer tube such that rotation of the rotate gear causes rotation of the outer tube. The shifter mechanism includes a shifter shaft that supports a shifter gear. The shifter shaft is movable to move the shifter gear between a rotate position in which rotation of the articulation gear causes rotation of the rotate gear and the outer tube and an articulate position in which the shifter gear prevents or locks rotation of the rotate gear and the outer tube.
