1. A method of operating a surgical instrument, the surgical instrument comprising an electric motor operably coupled to an end effector of the surgical instrument, a motor controller coupled to the electric motor, a sensing module, a processor, and a memory coupled to the processor, the memory storing executable instructions that when executed by the processor cause the processor to execute the method, the method comprising:

  • detecting tissue compression of a tissue grasped by the end effector by the sensing module;

    comparing the detected tissue compression to a predetermined tissue compression threshold;

    causing the motor controller to pause motion generated by the electric motor when the detected tissue compression reaches the predetermined tissue compression threshold; and

    causing the motor controller to automatically resume the motion generated by the electric motor.
