1. An untethered hand-held surgical instrument configured to operate in a plurality of operating states during a firing stroke, the plurality of operating states comprising an advancing firing member state, a paused firing member state and a retracting firing member state, the untethered hand-held surgical instrument comprising:

  • a handle;

    a multi-function electric motor positioned within the handle, wherein said motor is configured to;

    drive a firing member during the firing stroke; and

    generate a tactile feedback when the operating state of the hand-held surgical instrument is the paused firing member state;

    an amplifier positioned within the handle, wherein the amplifier is coupled to the motor and is configured to amplify the tactile feedback generated by the multi-function electric motor;

    a controller positioned within the handle, wherein the controller is for controlling said motor;

    a sensor configured to detect a force on the firing member, wherein the sensor and the controller are in signal communication, and wherein the controller is configured to change the operating state of the hand-held surgical instrument from the advancing firing member state to the paused firing member state by pausing an advancement of the firing member when the force on the firing member detected by the sensor exceeds a threshold force; and

    a plurality of input keys on the handle, wherein the input keys and the controller are in signal communication, wherein the controller is further configured to;

    while the force on the firing member exceeds the threshold force, change the operating state of the hand-held surgical instrument from the paused firing member state back to the advancing firing member state when a first input key is activated; and

    while the force on the firing member exceeds the threshold force, change the operating state of the hand-held surgical instrument from the paused firing member state to the retracting firing member state when a second input key is activated.
