1. A surgical system, comprising:

  • a handle housing including a rotatable actuation shaft;

    an elongated body including a flexible portion and a flexible drive shaft in the flexible portion, the elongated body couplable to the handle housing such that the flexible drive shaft couples to the actuation shaft; and

    a jaw assembly couplable to the elongated body, the jaw assembly including;

    first and second jaws, the second jaw defining a cam surface and pivotally movable relative to the first jaw from an open position to a closed position;

    a drive beam including a cam member positioned to engage the cam surface of the second jaw member, the drive beam longitudinally movable through the first and second jaw members such that the cam member is translated along the cam surface of the second jaw to move the first and second jaws from the open position to the closed position; and

    a drive screw supported within the first jaw, the drive screw including a threaded portion threadably coupled to the drive beam, the drive screw coupled to the flexible drive shaft configured to transfer rotational motion of the actuation shaft to the drive screw, such that rotation of the drive screw imparts longitudinal movement of the drive beam.
