Abstract
A stapling assembly comprising an end effector, a lockout circuit, a firing member, and a drive system is disclosed. The end effector comprises a first jaw and a second jaw. The second jaw is movable relative to the first jaw between an unclamped position and a clamped position. The lockout circuit is configured to detect if a staple cartridge is in the end effector. The firing member is movable between an unfired position and a fired position during a firing stroke. The drive system is configured to clamp the second jaw and advance the firing member through the firing stroke. The drive system comprises an electric motor, a selectively operable first planetary gear train, a selectively operable second planetary gear train, and a switching mechanism configured to switch between the operation of the first planetary gear train and the second planetary gear train.
