Claim 5:
6. A surgical fastener applier comprising:
a housing having a proximal opening at a proximal portion;
an elongated shaft extending distally from the housing and having a lumen dimensioned to receive a loading unit and terminating distally in an opening at a distalmost end; and
a loading unit having an elongated member, first and second jaws at a distal portion and a firing mechanism movable axially within the elongated member to effect firing of a plurality of surgical fasteners from the loading unit into tissue clamped between the first and second jaws, the loading unit insertable into the proximal opening of the housing and through the lumen of the elongated shaft to expose a portion of the elongated member and first and second jaws from the distalmost end of the elongated shaft, the loading unit configured to be inserted through the proximal opening when the elongated shaft is within a body of the patient, and the loading unit is configured to be removed from the surgical fastener applier while the elongated shaft remains in the body of a patient, the loading unit removable by proximal withdrawal from the lumen of the elongated shaft and proximal opening of the housing;
wherein the housing has a compartment to removably receive a power pack, the power pack interacting with the loading unit and having a motor, a motor shaft and an engagement member removably engageable with the firing mechanism of the loading unit at a proximal end of the surgical fastener applier, the engagement member movable to move the firing mechanism to effect powered movement of the firing mechanism of the loading unit from a first position to a second position to fire the plurality of surgical fasteners;
wherein the elongated member of the loading unit has an elongated slot to receive the engagement member of the power pack for engagement of a drive mechanism of the power pack with the firing mechanism of the loading unit.
