Patent attributes
A stapling device includes first and second jaws. The second jaw defines first and second threaded bores. A drive member has a distal end portion supporting a rack. An approximation drive assembly includes a first lead screw received within the first threaded bore. A second lead screw is received within the second threaded bore. A first pinion is supported on the first lead screw. A second pinion is supported on the second lead screw. Moving the drive member from the retracted position toward the advanced position advances the rack to rotate the first pinion and the second pinion, the first lead screw within the first threaded bore, and the second lead screw within the second threaded bore to move the second jaw in relation to the first jaw from an open position to a clamped position.
