Abstract
A surgical instrument and method for indicating that a cartridge has been fired includes an end effector receiving a cartridge having at least one of a knife and a plurality of staples, a shaft assembly connected to the end effector, and a handle assembly. The handle assembly has a handle housing, a firing member configured to selectively actuate from a first position to a second position as a firing stroke, and a feedback generator operatively connected to the firing member. The firing member is configured to actuate the cartridge from an unfired cartridge position to a fired cartridge position when the firing member is actuated. The feedback generator is configured to communicate an audible sound and a visual indicia to an operator indicative of the firing member completing the firing stroke for actuating the cartridge to the fired cartridge position.
