The present invention generally relates to cutting tools; and more particularly, to a cutting tool having straight flutes and being constructed to cut when oscillated in a rotary motion in either direction around a longitudinal axis.
The prior art has provided cutting tools that remove material when rotated. These tools typically include one or more helix cut into the tool; the helix all arranged in the same direction and parallel if more than one helix is present. The helix may be cut for left hand rotation or for right hand rotation of the tool. The leading edge of each helix is provided with a sharpened edge that cuts the material when rotated, while the helix moves the cut material away from the cutting action. The rear edge of the helix is provided with relief so as not to drag on the edge of the cut surface.
U.S. Pat. No. 9,232,953 issued to Bono, the inventor of the present cutting tool, provides a cutting tool for bone, cartilage and disc material that includes at least one helix arranged in a first direction and at least one helix arranged in a second direction so that the cutting tool can be oscillated back and forth to cut. However, it has been found that this construction may not remove material fast enough during oscillation for some surgical procedures.
Therefore, it would be desirable to provide a rotary cutter configuration that cuts both directions when oscillated back and forth to quickly cut bone, cartilage and disc, while minimizing any form of change to soft tissues during removal of the bone, cartilage and disc tissue.
Thus, the present invention provides a surgical rotary cutting tool which overcomes the disadvantages of prior art surgical cutting tools by providing a rotary surgical cutting tool having straight flutes with each side of the flute being provided with a cutting edge to provide cutting in both directions during limited oscillatory motion.
Briefly, 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.
Accordingly, is an objective of the present invention to provide a rotary surgical cutting tool that functions to cut bone, cartilage and disc materials.
It is a further objective of the present invention to provide a rotary surgical cutting tool that cuts bone, cartilage and disc materials when oscillated back and forth about a central axis, cutting when moved in both directions.
It is yet a further objective of the present invention to provide a rotary surgical cutting tool that cuts bone, cartilage and disc materials, and cutting in both directions when oscillated through limited oscillatory motion.
It is another objective of the present invention to provide a rotary surgical cutting tool having straight flutes, wherein each flute is provided with two opposing cutting surfaces.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of this specification, include exemplary embodiments of the present invention, and illustrate various objects and features thereof.
While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
