Abstract
A method for cutting a bone of a patient using a bone saw tool that includes determining a cutting region that corresponds to a region of the bone to be cut and determining the position of the bone saw tool in the coordinate system. The method includes activating a bone saw blade guard of the bone saw tool if the bone saw tool is outside the cutting region.
Claims9
A method for cutting a bone of a patient using a bone saw tool having a bone saw blade with a plurality of cutting teeth, the method comprising:
- determining a cutting region within a coordinate system defined by a computer assisted orthopaedic surgery system, the cutting region corresponding to a region of the bone to be cut;
- determining the position of the bone saw tool in the coordinate system;
- determining whether the bone saw tool has exited the cutting region defined in the coordinate system;
- and
- activating a bone saw blade guard of the bone saw tool based on a determination that the bone saw tool has exited the cutting region, the bone saw blade guard being devoid of any cutting teeth,
- wherein activating the bone saw blade guard comprises extending a plurality of slats of the bone saw blade guard with respect to the bone saw blade to cover a portion of the bone saw blade, each slat being positioned in a slot defined in the bone saw blade between each cutting tooth of the plurality of cutting teeth of the bone saw blade.
A method for cutting a bone of a patient using a bone saw tool having a bone saw blade with a plurality of cutting teeth, the method comprising:
- determining a cutting region within a coordinate system defined by a computer assisted orthopaedic surgery system, the cutting region corresponding to a region of the bone to be cut;
- determining the position of the bone saw tool in the coordinate system;
- determining whether the bone saw tool has exited the cutting region defined in the coordinate system;
- and
- reducing the cutting effectiveness of the cutting teeth of the bone saw blade of the bone saw tool based on a determination that the bone saw tool has exited the cutting region,
- wherein reducing the cutting effectiveness of the cutting teeth comprises activating a bone saw blade guard, the bone saw blade guard being devoid of any cutting teeth,
- wherein activating the bone saw blade guard comprises extending a plurality of slats of the bone saw blade guard positioned coplanar with the bone saw blade such that the plurality of slats extend beyond the cutting teeth of the bone saw blade, and
- wherein reducing the cutting effectiveness of the cutting teeth comprises altering the thickness of a bone saw blade assembly of the bone saw tool.
