Motor controlled surgical system

A surgical system adapted to operate with at least one surgical device, said surgical system having a handpiece containing a motor and adapted to receive and drive said surgical device, said surgical device being driven through a continuum of positions by said handpiece, said system comprising

• a controller,
• a motor drive circuitry driving said surgical device, said controller controlling said drive circuitry,
• a two wire switch bus,
• addressable switches, including at least one addressable Hall-effect device connected to and in electrical signal communcations with said bus, in said handpiece connected to said switch bus and responsive to electrical address signals from the controller over said switch bus for indicating a switch presence and a switch condition, and positioned in said handpiece for responding to magnetic field generating elements in a surgical device inserted into said handpiece, and said controller being responsive to electrical signals from said switches over the switch bus for controlling operation of said motor drive,
• said controller being responsive to signals indicative of a state of said at least one addressable Hall-effect device for presetting parameters corresponding to said surgical device,
• a foot switch connected to the controller for providing electrical signals identifying various foot switch commands, said foot switch including,
• an addressable switch having a Hall-effect switch and an actuating button element for modifying the state of the Hall-effect switch,
• said foot switch indicating to the controller, when polled, a switch state, and
• said controller, in response to said switch state, controlling operation of said motor.
