Abstract

A method for manufacturing an orthopedic product for a body part of a patient is disclosed, the method comprising the following steps: a) providing body-part data containing information about an internal structure of the body part, b) detecting a current line of vision from which a user of the method sees the body part, c) displaying the body part data from the current line of vision by means of the display device so that the user sees the body part and the body part data superimposed, d) generating production data for the orthopedic device on the basis of the displayed data and e) providing an orthopedic product manufactured on the basis of the production data.

First claim

The invention claimed is:

1. A method for producing an orthopedic product for a body part of a patient, the method comprising the following steps:
a) providing body part data that contains information about an inner structure of the body part,
b) detecting a current direction of view from which a user of the method sees the body part,
c) presenting the body part data from the current direction of view by means of a display device, so that the user sees the body part and the body part data superimposed,
d) generating production data for the orthopedic product on the basis of the data displayed, and
e) providing an orthopedic product produced on the basis of the production data, wherein prior to generating the production data, the body part is preferably deformed and/or molded and an electronic data processing device uses a model to calculate the effects of the deformation and/or molding of the body part on the inner structure of the body part and modifies the body part data accordingly, wherein the modified body part data is then displayed.

2. The method according to claim 1 , characterized in that the body part data is three-dimensional body part data.

3. The method according to claim 1 , wherein the display device is partially transparent, so that the user can look through the display device.

4. The method according to claim 1 , wherein image data of the body part is captured by means of a camera and/or a scan device at least also from the current direction of view, said image data being displayed superimposed on the body part data by means of the display device.

5. The method according to claim 1 , wherein, in order to generate the production data, three-dimensional product data is initially generated on the basis of the body part data and/or captured image data, on the basis of which the production data is generated.

6. The method according to claim 1 , wherein the body part data has been obtained by a medical imaging process or is obtained as part of the method prior to its provision.

7. The method according to claim 5 , wherein the three-dimensional product data is displayed using the display device, wherein it is preferably shown superimposed on the body part data.

8. The method according to claim 1 , wherein the body part data contains information on bones, muscles, nerves, blood vessels and/or soft tissues of the body part.

9. The method according to claim 1 , wherein three-dimensional product data adapted to the deformation and/or molding is generated in order to generate the production data.

10. The method according to claim 1 , wherein the deformation and/or molding of the body part is captured by means of at least one scanning glove and/or scan liner.

11. The method according to claim 1 , wherein, after generating the production data, the effects of a load and/or a movement of the body part when the orthopedic product is in mounted state on the body part are simulated and the result of this simulation is displayed by means of the display device.

12. The method according to claim 1 , wherein the direction of view can be changed.

13. The method according to claim 1 , wherein the direction of view is calculated from a position and orientation of the body part relative to the camera device, in particular a camera.

14. The method according to claim 13 , wherein the position and orientation of the body part relative to the camera device is calculated from the captured image data, the body part preferably featuring at least one marker, particularly a sticker and/or label.

15. A method for displaying body part data for use in a method according to claim 1 in which body part data is displayed in such a way that a user of the method sees the body part data and the body part superimposed from the current direction of view.

16. The method according to claim 15 , wherein the camera device and the display device fom1 part of a device to be arranged on a head of a user, especially glasses/goggles, a hood or a helmet.

17. A method for conducting a method according to claim 1 , the device comprising at least one camera device, at least one display device and at least one electronic data processing device.

18. A method for producing an orthopedic product for a body part of a patient, the method comprising the steps of:
providing three-dimensional body part data that contains information about an inner structure of the body part;
detecting a current direction of view from which a user of the method sees the body part; presenting the body part data from the current direction of view by means of a display device, so that the user sees the body part and the body part data superimposed, wherein the display device is partially transparent;
generating production data for the orthopedic product from the data displayed; and providing an orthopedic product produced from the production data, wherein prior to generating the production data, the body part is preferably deformed and/or molded and an electronic data processing device uses a model to calculate the effects of the deformation and/or molding of the body part on the inner structure of the body part and modifies the body part data accordingly, wherein the modified body part data is then displayed.
