Abstract:
A surgical instrument for cutting and stapling patient tissue is disclosed. The surgical instrument comprises an end effector including a staple cartridge and staples, a firing element configured to move through the staple cartridge to cut the patient tissue and eject the staples from the staple cartridge during a staple firing stroke, an elongate shaft extending from the end effector, and a handle extending from the elongate shaft. The handle comprises a motor configured to output a rotary motion. The firing element is operably responsive to the rotary motion. The firing element is further configured to be driven at different speeds during the staple firing stroke. The handle further comprises a display. The display is configured to display the different speeds of the firing element during the staple firing stroke as a graphical representation.
