Abstract
Systems and methods are provided for detecting misfire of a surgical staple cartridge and for indicating such misfire to a user on a user interface. An actuation force applied to a staple cartridge is measured and compared to a threshold actuation force. In response to the comparison, a controller determines if there has been a misfire of the surgical staple cartridge. A determination that misfire has occurred is made when the measured actuation force is greater than a maximum threshold force or less than a minimum threshold force, and under such circumstances, the controller terminates the staple firing sequence.
