Dual-bladed surgical saw and methods of use
First Claim
1. A dual-bladed surgical saw comprising:
- a saw body having a blade assembly attached thereto, the blade assembly being positioned about a rotational axis;
a first blade radially spaced about the rotational axis, extending outwardly from the blade assembly substantially parallel to the rotational axis, and terminating at a first cutting surface;
a second blade radially spaced about the rotational axis, extending outwardly from the blade assembly parallel to the rotational axis, and terminating at a second cutting surface;
an oscillator mechanism coupled to the first and second blades for simultaneously reciprocating the first and second blades;
wherein the first blade is independently rotatable relative to the second blade about the rotational axis for defining a predetermined cutting angle between the first blade and second blade.

Abstract
A dual-bladed surgical saw and methods of use are described. A preferred embodiment of the dual-bladed surgical saw include a saw body having a blade assembly attached thereto, the blade assembly being positioned about a rotational axis. A first blade is radially spaced about the rotational axis, extending outwardly from the blade assembly substantially parallel to the rotational axis, and terminating at a first cutting surface. A second blade is radially spaced about the rotational axis, extending outwardly from the blade assembly parallel to the rotational axis, and terminating at a second cutting surface. An oscillator mechanism is coupled to the first and second blades for simultaneously reciprocating the first and second blades. The first blade is independently rotatable relative to the second blade about the rotational axis for defining a predetermined cutting angle between the first blade and second blade.

11. A dual-bladed surgical saw comprising:
-
a saw body having a first blade assembly and a second blade assembly attached thereto; the first blade assembly including a first oscillator for reciprocating a first blade having a cutting surface at an end of the first blade opposite the first oscillator; the second blade assembly including a second oscillator for reciprocating a second blade having a cutting surface at an end of the second blade opposite the second oscillator; wherein the first blade is independently rotatable relative to the second blade about a rotational axis passing through the first and second blade assemblies for defining a predetermined cutting angle between the first blade and second blade. - View Dependent Claims (12, 13, 14)

15. A method of shaping bone for mating the bone with an implant having an implant surface adapted to abut the shaped bone when installed, the method comprising:
-
positioning blades of a dual-bladed surgical saw to a predetermined cutting angle, the dual-bladed surgical saw including a saw body having a blade assembly attached thereto, the blade assembly being positioned about a rotational axis; a first blade radially spaced about the rotational axis, extending outwardly from the blade assembly substantially parallel to the rotational axis, and terminating at a first cutting surface; a second blade radially spaced about the rotational axis, extending outwardly from the blade assembly parallel to the rotational axis, and terminating at a second cutting surface; and an oscillator mechanism coupled to the first and second blades for simultaneously reciprocating the first and second blades; simultaneously making first and second adjacent cuts separated by the cutting angle by contacting the bone with the first and second blades while the blades are reciprocating; and making a third cut adjacent to the second cut, the third cut being separated from the second cut by the same or a different cutting angle by passing the first blade across the second cut while the second blade makes the third cut. - View Dependent Claims (16, 17, 18, 19, 20)
