Abstract
An authentication and information system for use in a surgical stapling system includes a microprocessor configured to demultiplex data from a plurality of components in the surgical system. The authentication and information system can include one wire chips and a coupling assembly with a communication connection.
Claims20
A surgical system, comprising:
- a handle assembly;
- an adapter assembly releaseably coupled to the handle assembly;
- and
- a loading unit configured to support an end effector at a distal end thereof, the loading unit releasably coupled to the adapter assembly,
- wherein the loading unit includes:
- a microchip storing data indicative of one or more properties of the end effector, the microchip connected with a signal source via a single wire connection;
- and
- a microprocessor in communication with the microchip over a single-wire bus connection, the microprocessor including a ground wire and configured to switch the microchip between a receive mode and a transmit mode by switching the ground wire between ON and OFF positions,
- wherein the single wire connection between the signal source and the microchip is a separate connection from the single-wire bus connection between the microprocessor and the microchip.
