System for monitoring whether a surgical instrument needs to be serviced

An apparatus, comprising:

• a handle module comprising:
• a cavity configured for receiving a removable battery;
• at least one motor-driven rotary drive system;
• a handle module processor circuit;
• and
• a handle module memory circuit, wherein the handle module memory circuit is configured for storing handle module usage data for the handle module;
• a detachable shaft module removably attachable to the handle module, wherein the detachable shaft module comprises:
• a housing;
• a processor couplable to the handle module processor circuit, wherein the handle module and the detachable shaft module are configured to collectively perform a surgical procedure;
• and
• at least one switching device coupled to the processor of the detachable shaft module;
• and
• an inspection station configured for insertion into the cavity of the handle module when the handle module is not being used in the surgical procedure, wherein the inspection station comprises an inspection station processor circuit for determining one or more service recommendations for the handle module based on the handle module usage data stored in the handle module memory circuit of the handle module and based on service recommendation criteria.
