Abstract
A method of operating a surgical instrument is disclosed. The surgical instrument includes an electronic system comprising an electric motor coupled to the end effector; a motor controller coupled to the motor; a parameter threshold detection module configured to monitor multiple parameter thresholds; a sensing module configured to sense tissue compression; a processor coupled to the parameter threshold detection module and the motor controller; and a memory coupled to the processor. The memory stores executable instructions that when executed by the processor cause the processor to monitor multiple levels of action thresholds and monitor speed of the motor and increment a drive unit of the motor, sense tissue compression, and provide rate and control feedback to the user of the surgical instrument.
