Abstract: A surgical bur including a shaft with a head on the distal end of the shaft. A number of flutes extend outwardly from the head, each flute having a rake surface and a clearance surface. On some flutes the rake and clearance surfaces meet to form the flute cutting edges. Other flutes have relief surfaces between the rake and cutting surfaces. On these flutes, the cutting edges are the edges where the rake and relief surfaces meet. The flutes are further designed to have rake angles that are less negative, than the flutes without the relief surfaces. The flutes are radially spaced apart around the head such that between any three adjacent flutes, the first and second flutes are spaced apart a first angle; the second and third flutes are spaced apart a second angle different from the first angle.

Abstract: A sagittal saw blade with a blade body the distal end of which has spaced apart tines. Plural teeth extend forward from each of the tines. The void space between the tines functions as a chip catchment into which bone chips formed by cutting by the blade are able to flow. At least one web extends between the tines, across the chip catchment.

Abstract: A surgical bur including a shaft with a bur head. A number of flutes are formed on the bur head. Each flute has a cutting edge. Chamfer surfaces form the front, distally directed faces of some of the burs. The flutes without chamfer surfaces having cutting edges emerge from the bur head at locations relatively close to the distal end tip of the head. The flutes over which the chamfer surfaces extend have cutting edges that start, extend proximally rearward, from locations that are, spaced proximal from the distal end tip.

Abstract: A sagittal saw blade wherein the teeth are arranged so that relative to the teeth located closer to the outer sides of the blade, the inner located teeth are located closer to the proximal end of the blade. The blade is further formed to have an opening between at least two of the teeth that extends proximally rearward. The opening increases in width as the opening extends proximally along the length of the blade. The opening opens into a void space that functions as a chip catchment space.

Abstract: A surgical bur (20) including a shaft with a bur head. A number of flutes are formed on the bur head. Each flute has a cutting edge (54). The flutes are formed so that some of the flutes having cutting edges emerge from the bur head at locations relatively close to the distal end tip of the head. Still other flutes are formed so as to have cutting edges that start, extend proximally rearward, from locations that are, spaced proximal from the distal end tip.
