Prosthesis or orthosis for ankle
Recent advanced prostheses are too heavy, too expensive and lack autonomy.
Health systems are reluctant to pay a high price for high-tech devices such that the market remains focused on low-tech less expensive device. However, recent studies demonstrated the benefit of high-tech active devices, embedding motors and capable of providing energy for restoring a normal gait.
The UCLouvain invention
The new prosthesis includes a novel parallel spring locking mechanism that significantly decreases the energy consumption while offering high performance. The second innovation consists in a 3D printed compliant element embedded in the structural parts of the prosthesis that allows reaching requirements in terms of robustness, stiffness while decreasing the number of components and thus reducing the global cost and weight of the device.
