An actuator-damper unit for use in orthotic or prosthetic devices. The actuator-damper unit includes a housing which may be fastened on the orthotic or prosthetic device and in which a cylinder is formed. A first piston is displaceably mounted in the cylinder and is coupled to a piston rod. The piston rod is disposed, via a first end, on the first piston and may be coupled, via a second end, to the orthotic or prosthetic device. The first piston separates two fluid chambers in the cylinder from each other and forms a piston-cylinder unit, wherein at least one further piston is coupled to the first piston in order to form at least one further, variable-volume fluid chamber.

A joint device with an upper part and a lower part which are mounted on each other so as to be pivotable about a pivot axis, a hydraulic unit secured on the upper part and the lower part, and a housing in which a cylinder is arranged. A working piston is arranged in the cylinder and is coupled to at least one spring mechanism which transmits tensile forces and compressive forces and which engages on at least one abutment arranged displaceably inside the cylinder.

The invention relates to a method for creating manufacturing data for manufacturing an orthopedic product for a body part of a patient, the method comprising the following steps: providing a digital three-dimensional body part model of the relevant body part for which the orthopedic product is destined to an electronic data processing apparatus, the three-dimensional body part model being based on external body part data acquired from the body part of the patient; identifying at least one rigid body part region in the provided body part model by means of the electronic data processing apparatus, with the remaining region situated outside of the rigid body part region being identified as a yielding body part region on the basis of the identified rigid body part region; creating a reduced three-dimensional body part model by means of the electronic data processing apparatus on the basis of the provided three-dimensional body part model, the identified rigid body part regions and a reduction metric applied in the region of the yielding body part region; and producing manufacturing data for the orthopedic product on the basis of the reduced three-dimensional body part model by means of the electronic data processing apparatus.

Systems and methods for tuning a powered prosthesis are described herein. A system includes a powered prosthesis including a joint, a motor mechanically coupled to the joint, a plurality of sensors, a finite state machine, and an impedance controller. The sensors are configured to measure a plurality of gait parameters, and the finite state machine is configured to determine a gait cycle state. The impedance controller is configured to output a control signal for adjusting a torque of the motor, where the torque is adjusted as a function of the measured gait parameters and a plurality of impedance control parameters, and where the impedance control parameters are dependent on the gait cycle state. The system also includes a reinforcement learning controller operably connected to the powered prosthesis. The reinforcement learning controller is configured to tune the impedance control parameters to achieve a target gait characteristic using a training data set.

A prosthetic limb is made from a portable kit that is of relatively low cost and easy to assemble and custom fit to a person in need so that the person can wear the prosthetic immediately, without having to wait for the prosthetic to be manufactured off-site. The embodiments include a below the knee device and an above the knee device that includes an artificial knee. The improved prosthetic is suited for replacing a missing leg but can also be adapted to replace another body part such as an arm, hand or foot.

A prosthesis socket having a proximal insertion opening and an inner circumference which at least partially surrounds a limb stump, at least one connection device for a prosthesis component, which is connectable to the prosthesis socket, at least one actuator operable to change the inner circumference of the prosthesis socket, and at least one sensor coupled to a control device, wherein the control device is connected to the actuator and activates or deactivates same, depending on the received sensor signals, and to a method for adjusting the inner circumference.
