Abstract
A modular surgical instrument system that comprises modular components and a control circuit electrically couplable to the modular components. The modular components comprise a shaft and a handle assembly. The handle assembly comprises a disposable outer housing. The disposable outer housing is movable between an open configuration and a closed configuration. The handle assembly further comprises a control inner core receivable inside the disposable outer housing in the open configuration. The disposable outer housing is configured to isolate the control inner core in the closed configuration. The modular components further comprise a loading unit releasably couplable to the shaft and a staple cartridge releasably couplable to an end effector. The loading unit comprises the end effector. The control circuit is configured to generate an interrogation signal, detect a response signal, determine a modular configuration of the modular surgical instrument system, and assess authenticity of the modular configuration.
