Abstract

The invention relates to a method for producing a connecting element for connecting two components of an orthopedic device for a body part, wherein the method includes capturing three-dimensional scan data of at least one part of the body part by means of a scanner, determining a target position and/or target orientation of the connecting element relative to the body part from the scan data, modelling the connecting element using the scan data, the target position and/or the target orientation and information on the components to be connected, and producing the modelled connecting element.

First claim

What is claimed:

1 . A method for producing a connecting element of an orthopedic device for connecting two components of the orthopedic device for a body part, wherein the method comprises the following steps:
capturing three-dimensional scan data at least one part of each of the two components of the orthopedic device using a scanner, wherein the two components of the orthopedic device comprise two rigid components of the orthopedic device, and wherein the connecting element of the orthopedic device comprises a rigid connecting element of the orthopedic device or a joint comprising of the orthopedic device a joint axis, determining a target position and/or target orientation of the connecting element of the orthopedic device relative to the components of the orthopedic device and the body part from the scan data, modelling the connecting element of the orthopedic device using the scan data, the target position and/or the target orientation and information on the components of the orthopedic device to be connected, and producing the modelled connecting element of the orthopedic device.

2 . The method according to claim 1 , wherein at least one marking detectable by the scanner is applied to at least one of the two components of the orthopedic device before the scan data is captured.

3 . The method according to claim 1 , wherein at least one of the components of the orthopedic device and/or the connecting element of the orthopedic device comprises a joint of the orthopedic device.

4 . The method according to claim 1 , wherein the scan data are captured in at least two different positions and/or loads of the two components of the orthopedic device.

5 . The method according to claim 1 , wherein a simulation of the anticipated load is performed when modelling the connecting element of the orthopedic device, the result of which is included in the modelling of the connecting element of the orthopedic device.

6 . The method according to claim 1 , wherein the modelled connecting element of the orthopedic device is produced by an additive manufacturing process comprising a 3D printing process.

7 . A method for producing an orthopedic device with at least two components of the orthopedic device, which are also connected by a connecting element of the orthopedic device, wherein the method comprises the following steps:
producing the connecting element of the orthopedic device according to claim 1 ; and connecting the two components of the orthopedic device with the produced connecting element of the orthopedic device.

8 . The method according to claim 7 , wherein the two components of the orthopedic device each comprise at least one section which are arranged directly, in an articulated manner, by a free motion joint of the orthopedic device, against each other.

9 . The method according to claim 7 , wherein a fastening section of at least one of the two components of the orthopedic device is modelled after modelling the connecting element of the orthopedic device or during modelling of the connecting element of the orthopedic device using the scan data, the target position and/or the target orientation and information about the respective component of the orthopedic device.

10 . The method according to claim 7 , wherein at least one of the two components of the orthopedic device comprises a fiber composite component and the connecting element, wherein the connecting element is integrated into a layer structure of the fiber composite component.

11 . A method for producing a connecting element of an orthopedic device for connecting two components of the orthopedic device for a body part, wherein the method comprises the steps of:
applying at least one marking detectable by a scanner to at least one of the two components of the orthopedic device, wherein the two components of the orthopedic device comprise two rigid components of the orthopedic device, and wherein the connecting element of the orthopedic device comprises a rigid connecting element of the orthopedic device or a joint of the orthopedic device comprising a joint axis, capturing three-dimensional scan data of at least one part of each of the two components of the orthopedic device using a scanner in at least two different positions; determining a target position and/or target orientation of the connecting element of the orthopedic device relative to the components of the orthopedic device and the body part from the scan data; modelling the connecting element of the orthopedic device using the scan data, the target position and/or the target orientation and information on the components of the orthopedic device to be connected; and producing the modelled connecting element of the orthopedic device.

12 . The method according to claim 11 , wherein at least one of the components of the orthopedic device and/or the connecting element of the orthopedic device comprises a joint of the orthopedic device.

13 . The method according to claim 11 , wherein a simulation of the anticipated load is performed when modelling the connecting element of the orthopedic device, the result of which is included in the modelling of the connecting element of the orthopedic device.

14 . The method according to claim 11 , wherein the modelled connecting element of the orthopedic device is produced by an additive manufacturing process comprising a 3D printing process.

15 . A method for producing an orthopedic device with at least two components of the orthopedic device connected by a connecting element of the orthopedic device comprising the steps of:
producing a connecting element of the orthopedic device according to claim 11 ; and connecting the at least two components of the orthopedic device with the produced connecting element of the orthopedic device.

16 . The method according to claim 15 , wherein the at least two components of the orthopedic device each feature at least one section which are arranged in an articulated manner by a free motion joint of the orthopedic device against each other.

17 . The method according to claim 16 , wherein a fastening section of at least one of the two components of the orthopedic device is modelled after modelling the connecting element of the orthopedic device or during modelling of the connecting element of the orthopedic device using the scan data, the target position and/or the target orientation and information about the respective component of the orthopedic device.

18 . The method according to claim 16 , wherein at least one of the two components of the orthopedic device comprises a fiber composite component, and wherein the connecting element of the orthopedic device is integrated into a layer structure of the fiber composite component.

19 . A method for producing a connecting element of an orthopedic device for connecting two components of the orthopedic device for a body part, wherein the method comprises the steps of:
applying at least one marking detectable by a scanner to at least one of the two components of the orthopedic device, wherein the two components of the orthopedic device comprise two rigid components of the orthopedic device, and wherein the connecting element of the orthopedic device comprises a rigid connecting element of the orthopedic device or a joint of the orthopedic device comprising a joint axis, capturing three-dimensional scan data of at least one part of each of the two components of the orthopedic device using a scanner in at least two different positions; determining a target position and/or t
