DCFirst Claim
Patent Images
1. A surgical saw blade for use in combination with a surgical bone saw, the surgical saw blade comprising:
- a) a proximal end configured to couple to a surgical bone saw;
b) a distal end having an even number of substantially identically teeth for cutting bone, each of the plurality of teeth ending in a tip distally; and
c) a centrally positioned long axis between the proximal end and the distal end;
wherein each of the plurality of substantially identically shaped teeth are shaped substantially as right triangles including a hypotenuse and an angle opposite the hypotenuse, wherein each hypotenuse is oriented toward the centrally positioned long axis, and wherein the tips are arrayed on a line perpendicular to the centrally positioned long axis.

Abstract
A cutting saw blade for use with an oscillatory power tool used in surgical bone cutting procedures including a blade having a distal end provided with teeth whose tips are located on a tangent line perpendicular to the long axis of the blade. The teeth are configured substantially as right triangles with their hypotenuses facing either towards the center of the blade or away from the center of the blade. A central tooth can be optionally provided.

9. In combination, a surgical bone saw and a bone saw comprising:
-
a) an oscillatory or sagittal bone saw; and b) a surgical saw blade having; i) a proximal end configured to couple to a surgical bone saw; ii) a distal end having an even number of substantially identically shaped teeth for cutting bone, each of the plurality of teeth ending in a tip distally; and iii) a centrally positioned long axis between the proximal end and the distal end; wherein each of the plurality of teeth are substantially identically shaped substantially as right triangles including a hypotenuse and an angle opposite the hypotenuse, wherein each hypotenuse is oriented toward the centrally positioned long axis, and wherein the tips are arrayed on a line perpendicular to the centrally positioned long axis; and wherein the surgical saw blade is coupled to the oscillatory or sagittal bone saw. - View Dependent Claims (10, 11, 12)
