Surgical stapling system having a lockout mechanism for an incompatible cartridge
A surgical stapling instrument is disclosed a replaceable staple cartridge including a sled and an RFID tag. A lockout member includes a distal end. The distal end contacts a proximal portion of the sled as the replaceable staple cartridge is seated in the first jaw. A solenoid is configurable in an active configuration and an inactive configuration. The controller places the solenoid in an active configuration when the controller determines the replaceable staple cartridge is compatible for use with the surgical stapling instrument. The controller places the solenoid in an inactive configuration when an RFID scanner receives a signal from the RFID tag indicative that the replaceable staple cartridge is incompatible for use with the surgical stapling instrument. The lockout member pushes the sled distally as the replaceable staple cartridge is seated in the first jaw and the solenoid is in the inactive configuration.
