Description

[0038] In the following, an example of an embodiment of the present invention will be explained in more detail by way of the attached figures:

[0039] They show:

[0040] FIGS. 1 and 2—schematic representations of a leg prosthesis with markings for a method according to an example of an embodiment of the present invention,

[0041] FIG. 3—the schematic representation of a corresponding device.

[0042] FIG. 1 depicts a prosthesis 1 with various components 2. These are, from top to bottom, a prosthesis socket 4, a prosthetic knee joint 6, a lower leg element 8 and a prosthetic foot 10. Each of these components 2 features a marking 12 in the form of a QR code. Particularly in the case of the marking 12 arranged on the prosthesis socket 4, it is clear that the marking 12 can also be designed to be elongated. This facilitates the detection of an alignment and thus the orientation of both the marking 12 and the corresponding component 2.

[0043] FIG. 2 shows the prosthesis 1 with the previously specified components 2 and the markings 12; however, these are now designed differently. The marking 12 arranged on the prosthetic knee joint 6 is designed as shown in FIG. 1 and is, for example, printed on the prosthetic knee joint 6 or arranged on the element by means of a sticker. The marking 12 on the prosthetic foot 10 is arranged on a marking component 14, which is arranged on the prosthetic foot 10, for example via a magnetic interaction. Alternatively, the marking 12 can also be pushed onto the foot, wherein the position of the marking 12 can then be determined, for example, by end stops which are located, for example, on the forefoot and the heel. The markings 12 on the lower leg element 8 and on the prosthesis socket 4 are also arranged on the respective component via marking components 14. It can be seen particularly clearly on the prosthesis socket 4 that the marking component 14 is an elongated, plate-shaped element, which could be described as a rod, for example, on which the actual marking 12 is arranged. The elongated design of the marking 12 makes it easier to determine the orientation of the marking 12. The marking component 14 is arranged on the respective component 2 via two fastening strips 16, which may, for example, be in the form of straps, velcro fastening elements or adhesive elements. Again, the elongated shape of the marking component 14 facilitates the detection of the orientation of the marking component 14 and thus of the marking 12.

[0044] FIG. 3 schematically depicts a device 18 for performing one of the methods described here, said device being designed as a tablet. An output device 20 in the form of a display is shown on the one hand as a camera image of the detected prosthesis with the components 2 and on the other hand by the symbols 22 where markings have been detected. The symbol 22 includes a circle representing the position of the detected marking and two dash elements extending upwards and downwards in the example of an embodiment shown representing the orientation of the detected marking.

[0045] In addition, a force curve 24 is shown, which has been calculated either from the determined actual positions and/or actual orientations of the components 2 relative to each other or determined, for example, on the basis of force sensors or pressure sensors in a base plate, not shown, from the prior art. By means of the device 18 in the embodiment shown, it is no longer necessary to project detected or calculated lines onto the prosthesis itself or even onto the patient. It is sufficient for the calculated or detected lines to be displayed in the output device 20 of the device 18.
