Description

[0017] The invention is explained in more detail below with reference to the figures, in which:

[0018] FIG. 1 shows a prosthesis system having a plurality of prosthesis components;

[0019] FIG. 2 shows a system composed of prosthesis system and input device; and

[0020] FIG. 3 shows a schematic view of an embodiment of the prosthesis system of a first prosthesis component in the form of a forearm socket.

[0021] FIG. 1 shows a side view of a prosthesis system having two prosthesis components 10, 20. A first prosthesis component 10 is designed as a prosthetic lower leg with a prosthetic knee joint. The prosthetic knee joint has an upper part, which is mounted on a lower part so as to be pivotable about a pivot axis 14. A first mechatronic component 11, which is designed as an electronically controlled hydraulic damping device, is arranged inside the lower part. Arranged inside the mechatronic component 11 are actuators which are activated on the basis of sensor data and which are arranged, for example, on the first prosthesis component 10 and are connected to a control device that is assigned to the mechatronic component 11. By way of the actuators, settings are modified or valves are closed or opened or components are actively moved. Arranged at the proximal end of the first prosthesis component 10 is a pyramid adapter 13 by which it is possible to connect the prosthetic knee joint, as part of the first prosthesis component 10, to a thigh socket (not shown). A fastening device 12 is arranged or formed at the distal end of the first prosthesis component 10 and serves to receive a pyramid adapter 22 which is arranged in the proximal end of the second prosthesis component 20, the latter in the form of a prosthetic foot. In many cases, a tube adapter 23 or lower-leg tube is needed for coupling the prosthetic knee joint 10 or the lower leg part to the prosthetic foot 20.

[0022] The prosthetic foot 20 has a foot part, an ankle part, and an ankle joint axis 24 about which the ankle part can be pivoted relative to a foot part. A further mechatronic component 21, which can likewise be controlled electronically, is arranged inside the ankle part. Dampers or drives arranged inside the prosthetic foot 20 are adjusted or activated/deactivated on the basis of sensor data. The processing of the sensor data can take place separately in the respective prosthesis components 10, 20 or jointly in a common control device, with the sensor data being processed and evaluated. The control device has at least one microprocessor which is able, during the use of the prosthesis components 10, 20, to detect, capture and process the electronic sensor data and convert these into control signals for the respective drives or actuators. Storage elements are likewise provided in the control device or in the control devices in order to store data or programs. Separate and/or common energy accumulators can be assigned to the respective prosthesis component 10, 20.

[0023] The two prosthesis components 10, 20 can be fastened mechanically to each other. This is done by inserting the proximal pyramid adapter 22 of the prosthetic foot 20 into a corresponding fastening device 12 at the distal end of the lower leg part or of the first prosthesis component 10 or of a tube adapter 23.

[0024] Markers or identifiers can be arranged in the respective prosthesis component in order to make it possible, upon mechanical connection of two prosthesis components to each other, that the respective control device is informed of or detects which combination of prosthesis components is actually present. The markers or identifiers can also be interrogated wirelessly via an input device, such that the input device knows which components are intended to be configured and for which patient. The markers can be electronic markers, e.g. RFID or transponders, optical markers in the form of QR codes or other information carriers that are automatically readable.

[0025] In the illustrative embodiment shown, a transmitting and receiving device 15 is arranged on the first prosthesis component 10, making it possible to transmit information, to receive data of a control program for example, to install changes or updates, or to supply external devices with usage data that have been captured during the use of the prosthesis. The transmitting and receiving device 15 can be designed as a wireless interface or as a wired connection, for example as a socket.

[0026] FIG. 2 shows a system according to the invention having a total of four prosthesis components 10, 20, 30, 40 with which it is possible to manage a bilateral patient. The figure shows two prosthetic feet 20, 40 and two lower-leg components 10, 30 with prosthetic knee joints and proximal connector devices 13, 32. The basic set-up of the individual components corresponds to the set-up explained with reference to FIG. 1.

[0027] For the configuration of the overall system composed of a total of four prosthesis components 10, 20, 30, 40, a single input device 50 is provided which, in the illustrative embodiment shown, is designed as a tablet. Alternative input devices 50 are possible, for example a smart phone, a computer or another “smart” device. The input device 50 functions as master, while the four prosthesis components 10, 20, 30, 40 are designed as slaves which are supplied with data or information via the input device 50. The connection between the prosthesis components 10, 20, 30, 40 and the input device 50 is via wireless interfaces 51, 52, 53, 54, which are depicted symbolically. For example, data can be transmitted via a radio connection in a license-free ISM band, with what is called a Bluetooth connection. The connection can be bidirectional. Alternatively, other wireless interfaces or also wired interfaces can be arranged in order to transmit or exchange data via data exchange devices or transmitting and receiving devices 15, 35. Such transmitting and receiving devices can also be arranged or formed on the prosthetic feet 20, 40.

[0028] Whereas in the case of previous mechatronic components it was hitherto necessary, for the data transmission, the data exchange or the configuration, to connect each individual component to the input device 50 and separately adjust it or supply it with data, provision is made, according to the invention, that all of the mechatronic components 11, 21, 31, 41 are directly or indirectly connected simultaneously to one input device 50 which is designed as a master mobile device. The orthopedic technician thus has the possibility of transmitting all the input data simultaneously to all of the prosthesis components 10, 20, 30, 40, thereby permitting rapid feedback to the user of the prosthesis system. Conversely, in the case of bidirectional communication, the orthopedic technician has the possibility of obtaining all the data from all of the prosthesis components 10, 20, 30, 40 simultaneously with one interrogation, thus obtaining rapid feedback himself via the prosthesis system. In addition, by automatic comparison of the present components in a database to which the input device has access, parameters and parameters ranges can be predefined, and multiple inputs that are no longer needed can be faded out, such that not all of the user-specific data always have to be input for all the prosthesis components 10, 20, 30, 40. Through the bidirectional interfaces, it is possible that the input device 50 detects the present and combined prosthesis components 10, 20, 30, 40 and proposes or predefines parameters and parameter ranges that are adjustable. The orthopedic technician is able to choose whether the overall system is to be adjusted or the individual prosthesis components 10, 20, 30, 40 are to be adjusted.

[0029] FIG. 3 shows a schematic view of an embodiment of the prosthesis system of a first prosthesis component 10 in the form of a forearm socket or so-called brace which serves as a model of the actual forearm socket and does not yet have the full functionality of a forearm socket. A brace of this kind serves for training purposes and does not necessarily have fastening devices for the second prosthesis component 20, which is designed in the form of a prosthetic hand. In the illustrative embodiment shown, the second prosthesis component 20 is not mechanically fastened to the brace or to the forearm socket as first prosthesis component 10 but is instead arranged on a carrier 25. The carrier 25 has connectors or an interface for control signals and can also have a drive 4 for rotatable mounting of the prosthetic hand 20 or, if appropriate, drives for movable prosthetic fingers. In the illustrative embodiment shown, three drives 4 for actuation of the prosthetic fingers and of the prosthetic thumb are arranged inside the second prosthesis component 20 in the form of a prosthetic hand and can be activated and deactivated via control signals. The first prosthesis component 10 has a first sensor arrangement 6 with a plurality of electrode pairs 8, and a control device 2 in the form of an electronic data processing device. The customary electrical and electronic components are present in the control device 2, for example storage devices, data processing devices, processors, amplifiers and energy accumulators and, if appropriate, an input means and an output means and/or a display screen. Separate energy accumulators can likewise be provided. In addition, a wireless interface 51 is set up in the control device 2, via which interface the first prosthesis component 10 can be connected to the input device 50 in order to permit data exchange either in one direction or as a bidirectional data exchange.

[0030] The drive 4 arranged in the carrier 25 serves to rotate the first prosthesis component 10 or prosthetic hand relative to a final forearm socket of the prosthesis system about the longitudinal axis of the forearm socket.

[0031] The sensor arrangement 6 arranged in the brace has four electrode pairs 8. These are designed for example as individual electrode pairs 8 that can each be fastened to the skin of a prosthesis wearer. According to a further embodiment, the electrode pairs 8 are applied to a prosthesis liner (not shown), for example adhesively affixed to or connected integrally to a liner. The electrode pairs 8 are each connected to the control device 2 via sensor lines 16. By way of the sensor lines 16, the signals detected by the electrodes 8 are conveyed to the control device 2.

[0032] Besides the illustrated electrode pairs 8 as sensors for detecting myoelectrical signals, other sensors 8 are arranged on the forearm socket and can be designed as inertial sensors, IMUs, spatial sensors, acceleration sensors, force sensors, angle sensors, temperature sensors or other sensors. Several sensors 8 that detect different measurement variables or conditions can also be arranged on the orthopedic device. Similarly, sensors 8 can be arranged in the prosthetic hand, for example position sensors which detect the position of the prosthetic fingers. The signals of the sensors 8 are evaluated in the control device E.

[0033] In the present case, the control device 2 is connected wirelessly, for example by radio, to an input device 50. For example, signals obtained from the sensor arrangement 6 can be visualized via this input device 50. The control device 2 can likewise be connected wirelessly to the prosthetic hand as the second prosthesis component. There is likewise a radio connection to the carrier 25, for example. Alternatively, there may be a wired connection between the control device 2 and the second prosthesis component 20.

[0034] There is likewise the possibility of a considerable spatial separation between the second prosthesis component 20 and the control device 2 or the first prosthesis component 10. The first prosthesis component 10 or brace can be fitted in place by the user. The second prosthesis component 20 can be coupled to the control device 2, for example over the Internet, and a configuration of the overall prosthesis system can be effected via the input device 50. The input device 50 is only connected directly to the first prosthesis component 10 or the brace; the connection to the second prosthesis component 20 is effected via the first prosthesis component 10, i.e. indirectly.

[0035] By virtue of the spatial decoupling of the prosthesis components 10, 20 from each other, it is possible for an orthopedic technician to make mechanical adjustments to the prosthetic hand 20 in his workshop, while the user makes the individual adjustments via the first prosthesis component 10.

[0036] Alternatively, provision is made that the input device 50 adopts an intermediate position between the two prosthesis components 10, 20. By virtue of the bidirectional connection of the input device 50 to the first prosthesis component 10, it is possible to transmit sensor data of the sensors 8 to the input device 50. These sensor data are processed in the input device 50 and, by way of another communication interface, are sent to the remote second prosthesis component 20, which is in the form of a benchtop prosthetic hand. The orthopedic technician or the user himself can then see, e.g. via a video connection, which sensor signals lead to which reactions or control signals and therefore to corresponding movements by the drives 4 on the second prosthesis component 20, without a complete copy having to be made of a prosthesis socket with fixed positioning of the sensors. The configuration or the data transmission or the data exchange can thus proceed in parallel with the preparation of an individual forearm socket, which advantageously saves time in the management of patients.
