Hybrid saw blade
A surgical saw blade including a cutting edge, blade body and a coupling for connecting the blade body to a handpiece. The blade body at least partially includes a composite material that helps to confer optimal weight and rigidity to the saw blade to allow for minimal vibration during use and minimal mechanical load on the handpiece.
1. A saw blade comprising
a blade body having a top surface and a bottom surface, wherein the blade body is at least partially comprised of a first composite material;
a cutting edge on a distal end of the blade body; and
a coupling configured to connect the blade body to a handpiece adapted to oscillate the blade body,
wherein at least one of the top surface and the bottom surface of the blade body comprises an inlay portion comprising a second composite material; and
the inlay portion further comprises holes extending along a longitudinal axis of the blade body.
2. The saw blade of claim 1 , wherein the inlay portion is surrounded on all sides by a metal frame.
3. The saw blade of claim 2 , wherein the metal frame comprises steel.
4. The saw blade of claim 1 , wherein both the blade body and the coupling at least partially comprise the first composite material.
5. The saw blade of claim 1 , wherein the saw blade further comprises at least two of the materials selected from the group consisting of steel, polymer, titanium and ceramic.
6. The saw blade of claim 1 , wherein the first composite material is selected from the group consisting of a matrix material, a plastic material, a filling material and a carbon fiber fabric material.
7. The saw blade of claim 6 , wherein the first composite material is a carbon fiber fabric material.
8. The saw blade of claim 1 , wherein the cutting edge comprises a connector configured to mechanically interlock the cutting edge with the blade body.
9. The saw blade of claim 8 , wherein the connector comprises a plurality of holes configured to mechanically interlock with the first composite material of the blade body.
10. A saw blade comprising
a blade body having a top surface and a bottom surface, wherein the blade body is at least partially comprised of a first composite material;
a cutting edge on a distal end of the blade body; and
a coupling configured to connect the blade body to a handpiece adapted to oscillate the blade body,
wherein at least the top surface is a planar surface;
wherein the top surface of the blade body comprises an inlay portion comprising a second composite material;
wherein the inlay portion comprises holes extending along a longitudinal axis of the blade body.
