Abstract:
1. An apparatus for cutting, comprising: a flexible shaft configured to couple to a conversion means 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; wherein a cutting portion couples to the flexible shaft past a distal end of the catheter, and wherein the cutting portion is configured to cut bone when the flexible shaft moves it toward the catheter from which it projects; wherein the catheter is steerable in multiple planes, and wherein the cutting portion can cut while being steered in the multiple planes; a housing that includes a support; a motivation component fixed to the support, the motivation component including an output; a conversion means coupled to the output of the motivation component capable of converting an input motion to a backward and a forward motion, wherein the conversion means couples to the flexible shaft at an attachment point so that the conversion means converts rotational motion of into reciprocating motion of the flexible shaft at its proximal end; and wherein the conversion means converts an input motion into a reciprocating motion of the flexible shaft along a longitudinal axis of the flexible shaft.
