17. 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.

18. 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.

19. The method according to claim 17, wherein the camera device and the display device form part of a device to be arranged on a head of a user, especially glasses/goggles, a hood or a helmet.

20. 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.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0076] In the following, some examples of embodiments of the present invention will be explained in more detail by way of the attached figures: They show

[0077] FIGS. 1 and 2—schematic representations of process sequences and

[0078] FIG. 3—the schematic representation of image data and three-dimensional body part data.

DETAILED DESCRIPTION

[0079] FIG. 1 schematically depicts a structure and process sequence as can be used for an embodiment of the present invention. An orthopedic product is to be created for a schematically shown body part 2, which is depicted as an amputation stump. To this end, body part data 6 is first provided via medical procedures 4, for example. A wide variety of medical procedures 4 can be used. Different medical procedures 4 are shown, each of which is depicted schematically. Of course, more or fewer medical procedures 4 can be used to provide body part data 6.

[0080] Body part data 6 is supplied to an electronic data processing device 8, which features a display module 10. The body part data 6 is transmitted to this display module. The body part 2 is also captured by a camera device 12. It sends image data 14 to the electronic data processing device 8, in particular to the display module 10. The camera device 12 captures the body part 2 from the current direction of view. The camera device 12 may be based on visible light, UV light or infrared waves, and record corresponding images of the body part 2.

[0081] The display module 10 of the electronic data processing device 8 is configured to create a common image from the body part data 6 and the image data 14 made available to it and to display them superimposed. For this purpose, the device features a display device 16, for example a monitor. The display module 10 recognizes or knows the current direction of view and also displays the body part data 6 transmitted to it from the current direction of view in such a way that a user of the method, not depicted, is shown the body part data 6 and the image data 16 superimposed on the display device 16 from the same current direction of view.

[0082] The body part data 6 and the image data 14 are also transmitted to a generation module 18 of the electronic data processing device 8. On the basis of the transmitted data, it generates production data 20, which is transmitted to a production site 22. This may be a 3D printer, for example, or another production device.

[0083] FIG. 2 depicts another embodiment, which differs from the embodiment shown in FIG. 1 in one detail only. The body part 2 is not observed by a camera device 12, but by the user 24 of the method, schematically depicted as an eye. They are looking through the display device 16, for example AR goggles. The display device 16 is designed to be partially transparent, so that the user 24 sees both the body part 2 and the data provided by the display module 10. However, this only refers to body part data, particularly three-dimensional body part data 6 that has been determined and provided by the various medical procedures 4. Both in the process according to FIG. 1 and in the process according to FIG. 2, the body part data 6 is of course not provided directly by the medical procedures 4. Rather, they are created by the medical procedures 4 and stored in an electronic data storage device, not shown, which can be accessed by the electronic data processing device 8.

[0084] FIG. 3 schematically depicts the various data, which is shown superimposed. In the upper left area of FIG. 3, image data 14 of an amputation stump, i.e. a body part 2, is shown. In the upper right area, the bones 26 found in the interior of the body part 2 are depicted. This data has been generated by an MRI procedure, for example, and is stored in an electronic data storage device. It is therefore three-dimensional body part data 6. In the lower area of FIG. 3, the image data 14 and the three-dimensional body part data 6 are shown superimposed, as would be the case on the display device 16, for example, in the arrangement shown in FIG. 1.
