Methods and systems for detecting staple cartridge misfire or failure

Abstract

A surgical stapler system may include a surgical instrument comprising an end effector configured to receive a removable staple cartridge, and an actuation mechanism operably coupled to actuate the end effector to perform a stapling procedure. The surgical stapler system also may include a drive system operably coupled to transmit an actuation force to the actuation mechanism and a controller operably coupled to the drive system. The controller may be configured to measure an actuation force transmitted by the drive system to the actuation mechanism, and control continued transmission of the actuation force based on a comparison of the measured actuation force to a range defined from a minimum threshold actuation force to a maximum threshold actuation force.
