    a modular shaft assembly extending distally from the housing, wherein the modular shaft assembly is detachably coupled to the housing;

    an end effector extending distally from the modular shaft assembly, the end effector comprising;

    a first jaw member configured to support a removable staple cartridge; and

    a second jaw member movable relative to the first jaw member between an open position and a closed position;

    an axially movable drive member in operable communication with the second jaw member; and

    a rotary drive shaft in operable communication with the motor, wherein the rotary drive shaft is in operable engagement with the axially movable drive member, wherein at least one rotational motion of the rotary drive shaft causes the axially movable drive member to move the second jaw member relative to the first jaw member from the closed position to the open position.
