Abstract
A powered handle for a surgical stapler has a drive system including an electric motor. The powered handle includes a shaft recognition mechanism such that when a reload shaft for use with the surgical stapler is installed, a control system can actuate the drive system with the recognized shaft. The powered handle further comprises a LED light ring driven by a light control scheme to display a handle status. The control system also includes a startup module to assess hardware and control system performance before use. The startup module assesses different criteria depending on whether the handle is new, previously used, or previously reset. The control system of the powered handle further includes a lockout module configured to identify when a lockout has been encountered. The lockout module applies different criteria depending on whether the motor is operating at a maximum speed state or less than a maximum speed state.
