1. A surgical instrument, comprising:

  • a jaw assembly, comprising;

    a staple cartridge including a plurality of staples; and

    an anvil, wherein at least one of the staple cartridge and the anvil is movable relative to the other one of the staple cartridge and the anvil to capture tissue therebetween;

    a firing assembly configured to deploy the plurality of staples into the captured tissue during a firing sequence;

    a handle, comprising;

    an actuator; and

    an interface;

    a motor cartridge, wherein the interface is configured to releasably couple the motor cartridge to the handle, and wherein the motor cartridge comprises;

    an electric motor operably coupled to the firing assembly when the motor cartridge is coupled to the handle; and

    a motor control circuit, wherein the motor control circuit is configured to cause the electric motor to generate at least one rotational motion to motivate the firing assembly to deploy the plurality of staples into the captured tissue in response to actuation of the actuator;

    a feedback element; and

    a controller, comprising;

    a processor; and

    a computer-readable storage device storing program instructions, which when executed by the processor, cause the processor to;

    detect an error requiring the motor cartridge to be replaced;

    stop the electric motor in response to the error being detected;

    store a damaged status of the motor cartridge;

    indicate motor cartridge replacement instructions via the feedback element; and

    detect replacement of the motor cartridge with an undamaged motor cartridge.
