Abstract
The present invention relates to methods for validating the correct position of a patient-specific device on a chosen anatomy of the human body as well as such patient-specific devices. More specifically, the devices are provided with a fitting tool which allows in alignment of the patient-specific device with one or more predetermined patient-specific landmarks.
Claims14
A method for validating a correct position of a patient-specific device on an anatomical part of the human body, the method comprising:
- positioning the patient-specific device on the anatomical part, wherein the patient-specific device comprises:
- a patient-specific surface configured to be complementary with at least a portion of the anatomical part;
- a functional alignment element configured for optically aligning the device;
- and
- a patient-specific landmarking element configured to align with a predetermined anatomical landmark on the anatomical part when the patient-specific device is in the correct position,
- wherein the predetermined anatomical landmark is a visible, physical feature of the anatomical part when the patient-specific device is in the correct position,
- and wherein the patient-specific landmarking element is a beam configured to correlate with a width of the predetermined anatomical landmark;
- aligning the functional alignment element;
- and
- checking whether the patient-specific landmarking element aligns with the predetermined anatomical landmark on the anatomical part in order to validate the correct position of the patient-specific device on the anatomical part.

- wherein the predetermined anatomical landmark is a visible, physical feature of the anatomical part when the patient-specific device is in the correct position,
- and wherein the patient-specific landmarking element defines a curve configured to align with a portion of a contour of the predetermined anatomical landmark;
- aligning the functional alignment element;
- and
- checking whether the patient-specific landmarking element aligns with the predetermined anatomical landmark on the anatomical part in order to validate the correct position of the patient-specific device on the anatomical part.

- and wherein the patient-specific landmarking element is a ring configured to correlate with an outline of the predetermined anatomical landmark;
- aligning the functional alignment element;
- and
- checking whether the patient-specific landmarking element aligns with the predetermined anatomical landmark on the anatomical part in order to validate the correct position of the patient-specific device on the anatomical part.
