Abstract
A burr attachment removably attached to an adapter rotary driven by a motor that includes a tube with a wire shaft supported therein and a wire coil (no spring rate) serving as a journal bearing rotary supporting the wire shaft and having each of the coils randomly touch the outer periphery surface of the wire shaft and the inner peripheral surface of the tube to enhance cooling and attenuate vibrations while allowing the burr attachment to be bent without kinking. The burr attachment includes a proximal end support and a distal end support that removably attaches to the adapter. The wire shaft is affixed to the proximal end support and rotates relative to the distal end support operatively connected to the adapter. Only the burr attached is removable and disposable while the adapter and motor are re-usable.
