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.
