Method and system for shaving bone

A system for cutting, comprising:

• a housing that includes a support;
• a motivation component fixed to the support, the motivation component including an output;
• a conversion component coupled to the output of the motivation component capable of converting an input motion from the output into a backward and a forward motion;
• a flexible shaft coupled to the conversion component at a proximal end of the shaft, wherein a catheter slidingly covers the shaft substantially from the proximal end of the shaft to a distal end of the shaft;
• and
• wherein a cutting portion couples to the shaft past a distal end of the catheter.

A method for shaving bone, comprising:

• providing a housing that includes a support;
• energizing a motivation component fixed to the support, the motivation component including an output;
• wherein a conversion component couples to the output of the motivation component capable of converting an input motion from the output of the motivation component into a backward and a forward motion;
• wherein a flexible shaft couples to the conversion component at a proximal end of the shaft, wherein the catheter slidingly covers the shaft to substantially from the proximal end of the shaft to a distal end of the shaft, and wherein a cutting portion of the distal end of the shaft extends past a distal end of the catheter.
