1. A surgical fastener applier comprising:
a housing containing a compartment therein;
an elongated member extending distally from the housing;
a first jaw and a second jaw at a distal portion of the elongated member, at least the first jaw movable with respect to the second jaw to clamp tissue between the first and second jaws;
a firing mechanism positioned within the housing, the firing mechanism movable between a first position and a second position, wherein movement to the second position effects firing of fasteners into the tissue clamped between the first and second jaws; and
a power pack removably loadable into the compartment, the power pack having a first motor and a first engagement member removably engageable with the firing mechanism when the power pack is loaded into the compartment to effect movement of the firing mechanism from the first position to the second position, the first engagement member having a home position and an advanced position; wherein the power pack can be loaded into the compartment only if the first engagement member is in the home position.
