Surgical apparatus configured to assess whether a performance parameter of the surgical apparatus is within an acceptable performance band

A surgical apparatus, comprising:

• a handle module configured to receive a removable battery pack, wherein the handle module comprises:
• a latch movable from a first position to a second position;
• a rotary drive system;
• an electric motor coupled to the rotary drive system for powering the rotary drive system;
• one or more sensors for sensing data about the electric motor;
• and
• a handle module processor circuit in communication with the one or more sensors, wherein the handle module processor circuit is programmed to:
• monitor a performance parameter of the handle module based on input from the one or more sensors, and wherein the handle module processor circuit monitors the performance parameter of the handle module by monitoring whether the performance parameter of the handle module is outside an acceptable performance band;
• and
• control a movement of the latch from the first position to the second position after an end of life parameter of the surgical apparatus has been reached, wherein when the latch is in the second position:
• the latch is coupled to the removable battery pack;
• and
• the removable battery pack is prevented from being removed from the handle module;
• and
• a detachable shaft module releasably coupled to the handle module, wherein a proximal end of the detachable shaft module overlaps a distal end of the handle module, and wherein the detachable shaft module and the handle module are configured to collectively perform a surgical procedure.
