  • a shaft;

    a motorized system configured to generate a low torque rotary motion during a first operating mode and a high torque rotary motion during a second operating mode;

    a control system configured to switch between said first operating mode and said second operating mode, wherein said control system comprises a user interface configured to allow a user to selectively switch between said first operating mode and said second operating mode;

    an end effector, comprising;

    a first jaw, anda second jaw movable relative to said first jaw between an open position and a clamped position;

    an articulation joint disposed proximal to said end effector, wherein said end effector is rotatable relative to said shaft about said articulation joint;

    a drive member; and

    a rotatable member operably coupled with said motorized system, wherein said rotatable member is in operable engagement with said drive member, wherein said high torque rotary motion from said motorized system moves said drive member to drive said second jaw toward said clamped position, and wherein an opposite direction to release said second jaw and allow said second jaw to move toward said open position.
