Abstract
Surgical systems and related methods verify the presence of an unfired surgical cartridge mounted to a surgical instrument. The cartridge includes an input that is actuated in a firing direction to operate the cartridge. An actuation input that is limited to less than or equal to a predetermined magnitude is generated. The actuation input includes at least one of a torque or a force. The actuation input is transferred to an output of a surgical instrument to attempt to actuate the output opposite to the firing direction by a predetermined amount. The output is drivingly coupled with the cartridge input when the cartridge is mounted to the surgical instrument. The resulting actuation of the output is measured and compared with a threshold actuation amount. A determination is made that the cartridge is present and unfired when the resulting actuation of the output is less than the threshold actuation amount.
