1. A battery powered surgical apparatus comprising:
a handle including a housing;
an endoscopic portion extending distally from the housing and defining a longitudinal axis;
a fastening assembly coupled to a distal end of the endoscopic portion, the fastening assembly including a pair of jaws defining a stapling mechanism, at least one of the jaws being movable with respect to the other jaw;
a drive source proximal of the endoscopic portion, the drive source including a motor powered by a battery and connected to a drive shaft; and
a gear assembly engaged with the drive shaft of the motor, the gear assembly disposed within the housing and including:
a drive gear connected to a driving member configured to actuate the endoscopic portion; and
a main gear operatively connected with the drive gear, the motor being adapted and configured to spin the main gear such that rotary motion of the main gear moves the drive gear linearly in an axial direction within the housing, parallel to the longitudinal axis, to impart an axial force on a corresponding member in the endoscopic portion to engage and actuate the stapling mechanism in the fastening assembly.
