A surgical apparatus is disclosed which comprises a handle module that is attachable to a detachable shaft module for collectively performing a surgical procedure. The handle module comprises a rotary drive system for driving the detachable shaft module, an electric motor coupled to the rotary drive system for powering the rotary drive system, one or more sensors for sensing the performance of the electric motor, and a handle module processor circuit in communication with the one or more sensors. 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 by monitoring whether the performance parameter is outside an acceptable performance band. |
