1. A system for stapling tissue comprising:
a) a surgical stapler having a housing, an elongated shaft having a longitudinal axis and extending distally from the housing, and first and second jaws at a distal portion of the elongated shaft, at least one of the first jaw and second jaw is movable to a closed position to clamp tissue between the first and second jaws, the housing having a compartment and a cover, and an axially movable elongated firing mechanism positioned in and extending longitudinally within the compartment, wherein the compartment of the surgical stapler is openable to access the compartment and firing mechanism; and
b) a reusable power pack containing a motor and a rotatable member operatively connected to the motor to effect axial movement of the firing mechanism, the power pack removably loadable in the compartment of the surgical stapler to mechanically engage the firing mechanism positioned in the housing and the firing mechanism is accessible and engaged by the power pack when the cover is in an open position and the firing mechanism is inaccessible with the cover in a closed position as the firing mechanism is enclosed within the compartment, the firing mechanism is in a same axial orientation with respect to the elongated shaft when the cover is in the open and the closed position, the motor powering the surgical stapler to axially move the firing mechanism to sequentially fire staples from the first jaw through tissue into contact with an anvil supported at the second jaw for deformation of the staples, wherein the power pack is removable from engagement with the firing mechanism in the housing for subsequent mounting within and reuse in another surgical stapler for use in another procedure without requiring sterilization of the power pack.
