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 method of communicating data through a bus, the method comprising:
- providing a microprocessor capable of demultiplexing transmit and receive lines;
- providing a first microchip and a second microchip in a surgical system, each of the first and second microchips configured to provide authentication of a first component and a second component in the surgical system, each of the first and second microchips being communicatively-coupled through a bus to the microprocessor;
- and
- controlling a receive mode and a transmit mode over the bus.

A method of communicating data through a bus, the method comprising:
- authenticating a surgical component utilizing a microchip communicatively-coupled through a bus to a microprocessor capable of demultiplexing transmit and receive lines;
- and
- controlling a receive mode and a transmit mode over the bus.
A surgical system, comprising:
- a handle assembly having a controller, the controller having at least one program;
- an adapter assembly;
- and
- a loading unit having a tool assembly and at least one chip assembly having a chip storing data indicating whether the tool assembly articulates or not, the controller including a microprocessor configured for de-multiplexing data from said chip.
