Abstract

A surgical cutting instrument including an outer tube having a bearing sleeve disposed within a lumen thereof, along with an inner wire assembly extending through the outer tube and the bearing sleeve. A cutting tip is connected to the inner wire assembly distal the outer tube. Conversely, a coupling chuck is connected to a proximal section of the inner wire assembly, with a housing maintaining the outer tube and the coupling chuck. When mounted to a motor, the inner wire assembly is rotated to effectuate a surgical cutting procedure at the cutting tip, with the bearing sleeve supporting the inner wire assembly relative to the outer tube during rotation.
