Abstract:
1. A powered surgical handpiece, said handpiece having: a housing, said housing having a first bore with an open end for removably receiving a cutting accessory and that extends inwardly into said housing; a motor disposed in said housing, said motor including a coupling assembly disposed in the housing first bore for engaging the cutting accessory so that, upon actuation of said motor, the cutting accessory is driven by said motor; a locking assembly mounted to said housing, said locking assembly having a member that engages said cutting accessory so as to removably hold said cutting accessory in the housing first bore; and a flexible carrier, said flexible carrier having first and second sections, each section having a longitudinal axis wherein: the longitudinal axis of the second section is angularly offset from the longitudinal axis of the first section; conductive traces are formed on the sections and are connected to each other; the carrier first section is wound in a closed circular pattern and disposed in a portion of said housing the defines the housing first bore so that the conductive trace on the carrier first section forms a coil that extends circumferentially around said housing first bore that is capable of inductively exchanging signals with the cutting accessory; and the carrier second section extends proximally from the carrier first section through said housing so that the conductive trace on the carrier second section functions as a conductor internal to said housing that extends to said coil.
