Surgical Navigation System

Abstract

A powered surgical tool system capable of providing energization signals to plural powered surgical handpieces. The system includes a console to which at least one footswitch is attached. The footswitch can be mapped to control any one of the handpieces connected to the console. The console includes a display on which representations of the footswitch and handpieces connected to the console are presented. The representations of the handpieces are in different colors. When the footswitch is mapped to a specific handpiece, the representation of the footswitch is presented in the same color as the representation of the handpiece to which the footswitch is mapped. When plural footswitches are attached to the console, the representation of each footswitch is presented in a color corresponding to the color of the representation of the handpiece to which the footswitch is mapped.
