US Patent 9901344 Stapling assembly

A stapling assembly configured to be operably attached to a surgical system comprises a carrier operably supporting a cartridge assembly therein and an anvil. The stapling assembly further comprises a housing removably attachable to the surgical system and an axial drive assembly. The stapling assembly further comprises a motor supported within the housing, wherein the motor is operable to selectively transmit a rotary motion to the axial drive assembly. The motor can only transmit the rotary motion to the axial drive assembly when the housing is coupled to the surgical system and a power source is selectively coupled with the motor.
