Definitions

  • the following writing relates generally to instrumentalities for cutting bone during surgery. More particularly, the instant writing is directed to a saw blade adapted to be operatively coupled to an oscillatory (or sagittal) surgical power tool which reciprocates the cutting blade back and forth about a small arc.
  • the surgical saw blade may have a distal end having at least one pair of teeth configured to be adjacent to each other and each of the pair of teeth is configured as a right triangle each having a hypotenuse which is oriented at least one of towards and away from the centrally positioned long axis.
  • this writing discloses a surgical saw blade having at least one pair of opposed teeth shaped as right triangles .
  • This kicking or grabbing that occurs causes a loss of accuracy in the cut from the sudden, unpredictable movements of the saw and induces increased fatigue of the surgeon because of the greater tension that the surgeon must maintain in his hands and arms in anticipation of receiving this kicking or grabbing motion.
  • Another problem noted in existing blades involves the tendency of the saw to initially wander rather than to form a kerf.
  • One reason for this involves the nature of oscillatory cutter blades.
  • the handle portion of the saw remains stable because it is in the surgeon's control and remote from the cutting. However a blade (having a proximal end mounted into the oscillatory power tool) moves at a distal end that scribes an arc of a circle.
  • the natural tendency is to make a plunge type cut, i.e., move the tool and blade in a single direction, plunging the saw in the bone for cutting.
  • the direction of force imposed by the surgeon is intuitively coaxial with the long axis of the saw and blade.
  • prior art cutting blades having curved cutting heads will cause the tip of the tooth to either wander or kick.
  • the instant invention addresses the bone to be cut in a manner which reduces fatigue by the surgeon and vibration or impulses generated during the cutting process. More specifically, when a tooth profile parallels tangents to the arc of travel of the oscillatory cutter, the bone to be cut sees approximately one tooth at a time when the surgeon is making a plunge into the bone.
  • each working tooth progressively cuts more material than the previous working tooth so that collectively, all teeth contacting the bone to be cut make progressive contributions.
  • Three types of saw blades illustrative of these phenomena are disclosed * in the instant application.
  • One blade includes a series of cutting tips all oriented in a linear plane and the teeth which support these tips all have the general configuration of isosceles triangles.
  • a second form of cutting tool in which the tips of all of the teeth are also substantially in a horizontal plane, but the teeth which support these tips have a different contour from the first version.
  • a central-most tooth may be in the form of an isosceles triangle as in the first invention form, but the remaining teeth disposed outboard the central isosceles tooth are all substantially right triangles in which the vertical leg of the right triangle is oriented adjacent the central isosceles tooth and the hypotenuse portion is outboard from the central isosceles tooth. This provides a positive rake, and the most aggressive cut as the blade cuts progressively from the inside out.
  • a third form of cutting blade is shown in which the right
  • triangles of the second version have been oriented 180 so that the hypotenuse of each cutting tooth faces the center of the cutting blade.”
  • the "right” triangles may be "near"
  • the cutting blade may have a distal end having at least one pair of teeth having tips configured to be adjacent to each other and positioned one on each side of the elongated central axis of the blade.
  • Each of the pair of teeth is configured as a right triangle each having a hypotenuse which is oriented at least one of towards and away from the centrally positioned long axis.
  • a further attempt with the present invention is to provide a device as characterized above which minimizes the degree of heat buildup associated with the surgical cutting to reduce the thermal necrosis that attends cutting bone.
  • a further attempt with the present invention is to provi d e a device as characterized above which minimizes the backlash and kick that the surgeon experiences when using traditional blades.
  • a further attempt with the present invention is to provide a device as characterized above which can be relatively economically manufactured, lends itself to mass production techniques and is extremely durable in construction.
  • a further attempt with the present invention is to provide a device as characterized above which cuts aggressively and has a tendency to initially form a kerf, and self 'centers itself and cuts through the bone quickly within which the blade will reside.
  • a further attempt with the present invention is to provide a
  • surgical saw blade having a centrally positioned long axis, a proximal end configured to couple to a surgical bone saw and a distal end having at least one pair of teeth having tips for cutting bone which are configured to be adjacent to each other and wherein one of the pair of teeth is configured as a right triangle with a hypotenuse which is oriented at least one of towards and away from the centrally positioned long axis and the other of the pair of teeth configured as a right triangle with a hypotenuse which is oriented in a direction opposite to the hypotenuse of the one of the pair of teeth.

  • a further attempt with the present invention is to provide a surgical saw blade having between at least two additional teeth having tips and up to five additional teeth having tips for cutting bone all of which are substantially identically shaped as a right triangle including a hypotenuse and an angle opposite the hypotenuse with a hypotenuse which is,oriented in the same direction as the hypotenuse of the adjacent tooth defining the pair of teeth and wherein the tips of all of the teeth are arrayed substantially on a tangent perpendicular to the centrally positioned long axis.

  • the coefficient of friction between a surgical saw blade, the bone to be cut and a surgical saw cutting guide may affect the quality of the final bone cut due to possible sticking or lack of smooth movement of the surgical saw blade during a surgical procedure. It is envisioned that a lubricious surface treatment, such as a coating could be applied to the surgical saw blades, described herein, to reduce the coefficient of friction between a surgical saw blade, the bone to be cut and a surgical accessory, such as for example a surgical saw ' blade cutting guide.

  • the lower coefficient of friction of the lubricious surface treatment and or coating of this invention gives the surgical . saw blades a significantly enhanced ability to glide easily between the bone being cut, tissue that .comes in contact with the surgical saw blade and interpro imal contact between the surgical saw blade and surgical accessory contacted by the surgical saw blade during a procedure such as, for example, a cutting guide.
