Abstract: A stapling system configured to be operably engaged with a surgical device is disclosed. The stapling system comprises a staple cartridge carrier, a staple cartridge body, staples, drivers, a sled, an anvil, a housing removably attachable to the surgical device, and a drive system. The drive system comprises a rotatable shaft and a translatable drive member. The translatable drive member is selectively movable through the stable cartridge body when a rotary motion is applied to the rotatable shaft. The translatable drive member is configured to advance the sled to motivate the drivers to deploy the stables into tissue. The stapling system further comprises an electric motor operably engaging the rotatable shaft to selectively apply the rotary motion to the rotatable shaft. The electric motor is configured to receive power from a power supply only when the housing is attached to the surgical device.

Abstract: A removable stapling attachment configured to be operably attached to a surgical device is disclosed. The removable stapling attachment comprises a staple cartridge carrier and a staple cartridge body. The removable stapling attachment further comprises a plurality of staples removably stored in the staple cartridge body, an anvil supported relative to the staple cartridge carrier and movable from an open position to a closed position, and a housing.
