SwissProsthetics has developed a modular, robust, and affordable prosthetic SwissProsthetics has developed a modular, robust, and affordable prosthetic solution. The system consists of a shaft and different modules for activities such as cycling, swimming, or climbing that can be exchanged easily using a coupling system. The project started with Andreas Trojan, who struggled to find a suitable prosthesis for his daughter Sophia who was born without a left hand. In their experience, the procedure to obtain the first prosthesis was cumbersome, expensive, and solutions to enable playing the violin were not available. As a consequence, Andreas sought a collaboration with the ZHAW and later the Wyss Zurich to develop a pragmatic solution that supports his daughter and others in the same situation. The result is a modular system with exchangeable hands that has increased the quality of life of many people. Sophia, for example, can now easily attach the biking hand that helps to activate the brakes and switch to the swimming hand to allow for symmetric breaststrokes. We are very excited about this outcome and thus would like to enable other children and adults to also benefit from our solution. We strive to deliver our prosthetic device to all people in need.
Was ist das Besondere an diesem Projekt?
Our solution is unique in that we do not attempt to solve all problems with a single solution. Instead, we provide a modular solution, where each module caters to a specific activity. The modules are designed for bimanual tasks in a creative way. We are developing with the users, not just for them. Based on this input, we are providing an assistive device with a functional fun factor, e.g., a biking tool, swimming tool and even a climbing tool. This extends the possibilities and improves their life. Through the usage of a 3D software with a parameter-dependent design, we develop a 3D model that matches the requirements for fast mass customization of shafts.
The project has already led to an interim product which resulted out of one testing-day, two long-term test-phases, several user-tests in between and mechanical testing. Through these testing series, two functional shaft systems, called “katta” and “flexi” are made available via Open Source. Both systems are designed in a way that the assembly is easy and that almost all parts are printable, so that the user does not need any special tools to complete it. Currently, the parametric design of the outer shaft is being developed as well as the further refinement of various activity-based modular hands. Those are the products that will be commercialized by 2021. We aim to become an ETH spin-off by Q3 2020, already working on partnership with industry partners such as Materialise or FIT AG. In this stage, the project has already triggered additional funding from Innosuisse.
