1. 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 a 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 to effect powered movement of the firing mechanism of the loading unit from a first position to a second position to fire the surgical fasteners;
wherein the power pack includes a second engagement member, the second engagement member removably engageable with an articulating mechanism in the loading unit to effect articulation of the first and second jaws from a linear position to a position angled with respect to a longitudinal axis of the elongated member, wherein movement of the second engagement member moves the articulating mechanism.
