First Claim
1. A battery powered surgical apparatus comprising:
- a housing;
an endoscopic portion extending from the housing;
a fastening assembly coupled to 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; and
a drive source disposed within the housing, the drive source including a motor powered by an internal battery, the motor adapted and configured for spinning a first gear, the first gear being in contact with a second gear such that rotation of the first gear rotates the second gear, the second gear being operatively connected to a drive member and a collar such that upon rotation of the second gear the collar cooperates and engages the drive member to move the drive member along a longitudinal axis.

Abstract
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.
