1. A method for controlling an electromechanical surgical system that includes a hand-held surgical instrument selectively and removably supporting an end effector, wherein the surgical instrument includes a motor, a controller in electrical communication with the motor, a battery in electrical communication with at least one of the motor and the controller, and at least one input element actuatable by a user to send control signals to the controller to operate the motor;

  • and wherein the end effector includes a jaw assembly, a drive assembly at least partially located within the jaw assembly and operatively connectable to the motor when the end effector is connected to the surgical instrument for actuation by the motor, the method comprising;

    monitoring the at least one input element;

    removing the battery from the surgical instrument;

    re-inserting the battery into the surgical instrument;

    entering an emergency retraction mode in response to the removal and re-insertion of the battery into the surgical instrument; and

    activating the motor during the emergency retraction mode to withdraw the drive assembly from any advanced position thereof.
