Surgical saw blade

摘要

A method of cutting bone comprising the steps of:
a) providing a surgical saw blade having a proximal end configured to couple to a surgical bone saw, a distal end having a plurality of substantially identical teeth having tips for cutting bone, each of the plurality of teeth ending in a tip distally and a centrally positioned long axis between the proximal end and the distal end and wherein said distal end a plurality of substantially identical teeth for cutting bone include 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 has a hypotenuse which is oriented at least one of towards and away from the centrally positioned long axis and the other of said pair of teeth has a hypotenuse which is oriented in a direction opposite to the hypotenuse of said one of the pair of teeth and wherein the tips are arrayed substantially on a tangent perpendicular to the centrally positioned long axis, and wherein said distal end has extending from each of said pair of teeth at least one additional tooth having a tip for cutting bone which is 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 said pair of teeth and wherein the tips of the additional teeth are arrayed substantially on a tangent perpendicular to the centrally positioned long axis;
b) coupling the surgical saw blade to a surgical saw;
c) actuating the surgical saw with the coupled saw blade; and
d) cutting the bone.
