Abstract

A dual bladed surgical saw and method of use. Two blade assemblies are attached to a saw body. Each blade assembly includes an oscillator driving a blade, and teeth on each blade. The blades are disposed at a pre-determined blade angle relative to each other, thus allowing two cuts to be made simultaneously and independently at the blade angle relative to each other. The blade assemblies may be rotatable relative to each other, which allows the pre-set blade angle to be varied appropriate to the procedure contemplated. One embodiment uses a slotted protractor bearing protractor indicia, and a threaded fastener to set the blade angle. Another embodiment uses shims between blade assembly arms to quickly and accurately set the blade angle. Method steps include pre-setting the blade angle, and making two cuts simultaneously at an angle relative to each other equal to the blade angle.
