Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 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. 2 . 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. 3 . The saw blade of claim 1 , wherein at least one of the top surface and the bottom surface of the blade body comprises an inlay portion comprising a composite material. 4 . The saw blade of claim 3 , wherein only the top surface of the blade body comprises an inlay portion comprising a composite material. 5 . The saw blade of claim 1 , wherein the composite material is selected from the group consisting of a matrix material, a plastic material, a filling material and a carbon fiber fabric material. 6 . The saw blade of claim 5 , wherein the composite material is a carbon fiber fabric material. 7 . The saw blade of claim 3 , wherein the inlay portion further comprises holes extending along a longitudinal axis of the blade body. 8 . The saw blade of claim 3 , wherein the inlay portion is surrounded on all sides by a metal frame. 9 . The saw blade of claim 8 , wherein the metal frame comprises steel. 10 . The saw blade of claim 1 , wherein the cutting edge comprises a connector configured to mechanically interlock the cutting edge with the blade body. 11 . The saw blade of claim 10 , wherein the connector comprises a plurality of holes configured to mechanically interlock with the composite material of the blade body. 12 . The saw blade of claim 1 , wherein the saw blade is configured to limit flexing to about 0.25 mm or less upon application of a 2.2N load. 13 . A saw blade comprising a blade body having a top surface and a bottom surface; 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 both the blade body and the coupling at least partially comprise a composite material. 14 . The saw blade of claim 13 , wherein the saw blade further comprises at least two of the materials selected from the group consisting of steel, polymer, titanium and ceramic. 15 . The saw blade of claim 13 , wherein the composite material is selected from the group consisting of a matrix material, a plastic material, a filling material and a carbon fiber fabric material. 16 . The saw blade of claim 15 , wherein the composite material is a carbon fiber fabric material. 17 . The saw blade of claim 13 , wherein the blade body comprises holes extending along a longitudinal axis of the blade body. 18 . The saw blade of claim 13 , wherein the cutting edge comprises a connector configured to mechanically interlock the cutting edge with the blade body. 19 . The saw blade of claim 18 , wherein the connector comprises a plurality of holes configured to mechanically interlock with the composite material of the blade body. 20 . The saw blade of claim 13 , wherein the saw blade is configured to limit flexing to about 0.25 mm or less upon application of a 2.2N load.
