Abstract
Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridge for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch for maintaining the locking member in the disabled position. The switch may be further configured to operate as a reload detection mechanism for determining the type of reload present in the surgical stapling instrument.
