Abstract
A powered handle assembly includes a motor assembly, a toothed rack, a drive gear, a clutch assembly, a manual retraction gear, and a retraction knob. The motor assembly is coupled to the drive gear, and the drive gear is movable from a first position engaged with the rack to a second position disengaged from the rack. The clutch assembly includes a lower gear and an upper gear that is coupled to the retraction knob and movable to a position engaged with the lower gear. The lower gear is engaged with the manual retraction gear and the manual retraction gear is engaged with the rack such that rotation of the retraction knob causes longitudinal movement of the rack. The handle assembly allows for manual retraction of a drive assembly of the surgical device when power is lost, or components are damaged.
