Abstract
A surgical guide tool and methodology includes a non patient-specific platform including one or more supports for attaching to a body part of a subject. A non patient-specific block has a top planar surface and a bottom planar surface, and includes a guide aperture extending from the top planar surface to the bottom planar surface for guiding a surgical instrument in making at least one of a cut and a drill hole. An intermediate module is removably positioned between the platform and the block. The intermediate module has patient-specific dimensions such that the guide aperture has a desired alignment relative to the body part when the surgical guide tool is attached to the body part of the patient and the intermediate module is positioned between the platform and the block.

A surgical guide tool comprising:
- a non patient-specific platform including one or more supports configured to attach to a body part of a subject;
- a non patient-specific block having a top planar surface and a bottom planar surface, the block including a guide aperture extending from the top planar surface to the bottom planar surface for guiding a surgical instrument in making at least one of a cut and a drill hole, and
- an intermediate module removably positioned between the platform and the block such that the block rests on top of the intermediate module without being inserted into the intermediate module, the intermediate module having patient-specific dimensions, and configured such that the guide aperture has a desired alignment relative to the body part when the surgical guide tool is attached to the body part of the subject and the intermediate module is positioned between the platform and the block.
A method comprising:
- providing a non patient-specific platform configured to attach to a body part of a subject;
- providing a non patient-specific block having a top planar surface and a bottom planar surface, the block including a guide aperture extending from the top planar surface to the bottom planar surface for guiding a surgical instrument;
- obtaining electronic image data of an anatomical area of the subject;
- determining a trajectory for at least one of a cut and a drill hole based, at least in part, on the electronic image data;
- providing an intermediate module configured to be removably positioned between the platform and the block such that the block rests on top of the intermediate module without being inserted into the intermediate module, the intermediate module having patient-specific dimensions such that the guide aperture in the block is configured to guide the surgical instrument in making the at least one of a cut and drill hole along the determined trajectory when the platform is attached to the body part of the subject and the intermediate module is sandwiched between the platform and the block.
