A surgical stapler has a handle assembly including a stationary handle and a trigger. The stapler also has a drive assembly with a body having a working end and a cam member supported on the working end. The cam member is positioned to translate relative to the anvil to maintain the anvil in the closed position during firing of the stapler. The trigger is operatively connected to a power cell. The power cell is operably connected to a motor of the drive assembly. The manipulation of the trigger actuates the power cell such that the power cell powers the drive assembly to effect translation of the cam member relative to the anvil. The stapler also has a channel for supporting the staple cartridge and the motor of the drive assembly controls the actuation sled supported within the cartridge. The actuation sled urges the plurality of staples from the cartridge when the anvil is in the closed position and in cooperative alignment with the staple cartridge.

1. A battery powered surgical apparatus comprising: a handle including a housing;an endoscopic portion extending distally from the housing;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; anda gear assembly engaged with the drive shaft of the motor, the gear assembly disposed within the housing and including a main gear operatively connected with a driving member, the motor being adapted and configured to spin the main gear such that rotary motion of the main gear moves the driving member linearly in an axial direction within the housing to impart an axial force on a corresponding member in the endoscopic portion to engage and actuate the stapling mechanism in the fastening assembly. 2. The battery powered surgical apparatus of claim 1, wherein the driving member is a gear rack. 3. The battery powered surgical apparatus of claim 1, wherein the driving member is a drive screw. 4. The battery powered surgical apparatus of claim 1, wherein the gear assembly further includes at least one subordinate gear. 5. The battery powered surgical apparatus of claim 4, wherein the main gear is a spur gear. 6. The battery powered surgical apparatus of claim 4, wherein the at least one subordinate gear is a pinion gear. 7. The battery powered surgical apparatus of claim 4, including two subordinate gears. 8. The battery powered surgical apparatus of claim 1, wherein the drive source is disposed within a protective housing connected to an outside surface of the housing and the drive shaft extends into the housing to engage the gear assembly. 9. The battery powered surgical apparatus of claim 1, wherein the driving member includes a bottom driving surface connected to the main gear. 10. The battery powered surgical apparatus of claim 1, wherein the main gear and the driving member are in contact with a second gear such that rotation of the main gear rotates the second gear, and the second gear engages the driving member to move the driving member along a longitudinal axis.
