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.
Claims22
A surgical guide tool comprising:
- a non patient-specific platform including one or more supports for attaching to a body part of a subject;
- a patient-specific block having a top surface and a bottom surface, the block including a guide aperture extending from the top surface to the bottom surface for guiding a surgical instrument in a making at least one of a cut and a drill hole, the block 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 patient and the block is braced against the platform, wherein the entire top surface and the entire bottom surface of the block are planar and non-parallel.
A method comprising:
- providing a non patient-specific platform for attaching to a body part of a subject;
- obtaining electronic image data of an anatomical area of the subject;
- determining a trajectory for making at least one of a cut and a drill hole based, at least in part, on the electronic image data;
- and
- providing a patient-specific block having a top surface and a bottom surface, the block including a guide aperture extending from the top surface to the bottom surface for guiding a surgical instrument in making at least one of a cut and a drill hole, the block having patient-specific dimensions and configured such that the guide aperture is configured to guides the surgical instrument in making the at least one of a cut and drill hole along the determined trajectory when the surgical guide tool is attached to the body part of the patient and the block is braced against the platform, wherein the entire top surface and the entire bottom surface of the block are planar and non-parallel.
