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.
Claims13
A surgical system, comprising:
- a handle assembly;
- a controller disposed within the handle assembly and configured to control operation of the surgical system;
- an adapter assembly releaseably coupled to the handle assembly;
- and
- a surgical stapling loading unit configured to support a staple cartridge assembly at a distal end thereof, the surgical stapling loading unit releasably coupled to the adapter assembly,
- wherein the surgical stapling loading unit includes:
- a microchip in communication with the controller over a bus connection, the microchip storing data indicative of one or more properties of the surgical stapling loading unit or the staple cartridge assembly;
- and
- a microprocessor disposed within the surgical stapling loading unit and in communication with the microchip over a single-wire bus connection separate from the bus connection between the microchip and the controller, 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.

A surgical stapling loading unit for use in a surgical system, comprising:
- a staple cartridge assembly;
- a microchip storing data indicative of one or more properties of the staple cartridge assembly, the microchip configured to communicate, over a bus connection, with a controller configured to control operation of the surgical system;
- and
- a microprocessor in communication with the microchip over a single-wire bus connection separate from the bus connection between the microchip and the controller, 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.
