US Patent 10441280 Robotically-controlled shaft based rotary drive systems for surgical instruments

A stapling assembly for use with a robotic device is disclosed. The stapling assembly comprises a first jaw, a second jaw rotatable relative to the first jaw between an open position and a closed position, an elongate shaft coupled to the first jaw, and a housing coupled to the elongate shaft. The housing comprises rotatable inputs operably engageable with the robotic device. A first system is configured to position the second jaw relative to the first jaw at a first rate. A second system is configured to position the second jaw relative to the first jaw at a second rate which is faster than the first rate.
