Abstract:
1. An apparatus for removing a strip of a rigid orthopedic material, the apparatus comprising: a cutting wheel assembly comprising a hub, a first cutting wheel and a second cutting wheel, the hub having a smaller diameter than a diameter of the first cutting wheel and a diameter of the second cutting wheel, wherein the hub is coupled between the cutting wheels to form a passage between an inner face of the first cutting wheel and an inner face of the second cutting wheel; and a shear coupled to the cutting wheel assembly and positioned below the passage, the shear comprising a top surface having a first edge configured to be engaged with the inner face of the first cutting wheel, and a second edge configured to be engaged with the inner face of the second cutting wheel; wherein at a point tangential to the rigid orthopedic material, the first and second cutting wheels rotate in a direction opposite to the removal direction to cause the cutting wheel assembly and the shear to exert opposing forces on the rigid orthopedic material; wherein the shear is configured to allow the material to pass over the top surface and be fractured by the cutting wheel assembly into a predetermined width defined by the first and second edge; and further comprising a deflector positioned within the passage and above the shear.
