Abstract
The present invention provides a cutting tool for surgical procedures. More specifically, the present invention provides a rotary surgical cutting tool which overcomes the disadvantages of prior art surgical cutting tools by providing a rotary cutting tool having straight flutes, with each side of the flute being provided with a cutting edge that permits cutting in both directions during limited oscillatory motion of the rotary surgical cutting tool. The areas between the cutting edges are provided with relief to reduce friction while the flute moves the cut material away from the cutting edges.
Claims19
A surgical cutting tool comprising:
- a shank having a longitudinal axis, said shank having a perimeter surface extending around said longitudinal axis, said perimeter surface being symmetrically arranged to allow said perimeter surface to be gripped for rotation about said longitudinal axis, whereby said longitudinal axis is also a rotational axis, said shank also including a first end and a second end;
- said first end of said shank including a cutter, said cutter including an outside diameter, said cutter including two or more flutes, each said flute extending parallel to said longitudinal axis and extending inward from said outside diameter, forming a recessed flute channel, each said flute channel having a pair of opposing sidewalls, each said sidewall forming a face of a cutting edge extending along the length of each said flute channel, whereby each said flute channel provides two opposing cutting edges to a blade so that said cutting tool cuts in both directions when rotationally oscillated around said rotational axis.
