Abstract
A surgical instrument is disclosed. The surgical instrument includes an elongate channel configured to support a staple cartridge, an anvil connected to the elongate channel, a movable cam member, an elongate shaft connected to the elongate channel, a housing coupled to the elongate shaft, and a transmission system. The anvil is movable between an unclamped position and a clamped position. The housing comprises a first rotary drive member, a second rotary drive member, a third rotary drive member and a fourth rotary drive member, each configured to be driven by a robotic surgical device. The transmission system is coupled to the first rotary drive member and is configured to drive at least two independent motions of the surgical instrument based on a rotation of the first rotary drive member. The at least two independent motions include a clamping motion and a firing motion.
