Abstract:
1. A burr attachment comprising: an elongated tube having an end and an inner surface, a wire shaft rotatably supported in said tube and having an outer surface, a cutter attached to said wire shaft and extending a predetermined distance from the end of said elongated tube, a tightly-wound coil wire non-rotatably mounted between the inner surface of said elongated tube and said wire shaft and surrounding and rotably supporting said wire shaft, said burr attachment being disposable and bendable without forming kinks therein, a distal end support including a central bore extending axially therethrough, said central bore sized and configured to receive the elongated tube and the wire shaft, the distal end support having a generally cylindrical main body including a small diameter portion at a proximal end of the distal end support and a larger diameter portion at a distal end of the distal end support, and a flat formed on a periphery of the larger diameter portion, and a proximal end support including a central bore sized and configured to receive the small diameter portion of the distal end support for matingly engaging the proximal and distal end supports together, wherein a proximal end of said proximal end support is fixedly attached to a proximal end of said wire shaft, and said proximal end support being rotatable relative to said distal end support for rotating the wire shaft, whereby the distal end support and the proximal end support are adapted to fit into an adapter driven by a motor for imparting rotary motion to said wire shaft.
