DeTOP Project: a new frontier of osseointegrated upper limb prostheses

PRESS RELEASE

DeTOP (Dexterous Transradial Osseointegrated Prosthesis with neural control and sensory feedback) is a collaborative project funded by the European Commission. The project is coordinated by the BioRobotics Institute of Sant’Anna School of Advanced Studies, Pisa – Italy and involves European universities, research centres and SMEs: Goeteborgs Universitet, Lund Universitet, University of Essex, Prensilia Srl, Integrum AB, Centre Suisse d’Electronique de Microtechnique.

DeTOP aims to create a new frontier of upper limb prostheses able of reproducing the functionality of the natural hand. Key objective is to translate, exploit and appraise already proven technology for trans-humeral amputation to the most frequent case of transradial amputation. In particular DeTop aims to develop a technology that is based on the use of osseointegration as a long-term stable solution for the direct skeletal attachment of limb prostheses. This solution allows to create more efficient bidirectional links between an individual and a robotic prosthesis and was pioneered by Goeteborgs Universitet and Integrum AB.

The project will develop: an osseointegrated human-machine gateway for transradial amputation, a smart mechatronic coupling for connecting the human-machine to the prosthesis allowing safe wrist rotation; a dexterous hand-wrist prosthesis with tactile sensors; a physiologically appropriate myocontroller based on implanted electrodes; neural feedback algorithms for restoring natural tactile sensations; miniature processing and communication nodes for control and sensory feedback.

“DeTOP is an important project that can open new scenarios for the future of robotic prostheses – Christian Cipriani, Associate Professor at the Scuola Sant’Anna and Coordinator of DeTOP, says – The system allows to assess the so called human-machine gateway in transradial amputees, in conjunction with a highly dexterous hand prosthesis; this will allow to assess for the first time close-to-natural control and sensory feedback outside out the laboratory”.

The new transradial prosthesis will be assessed by three selected patients, implanted in a clinical centre, in Gothenburg, Sweden. The DeTOP partners will constantly monitor the results that will produce a significant impulse in terms of scientific knowledge both in terms of clinical and technological implementation.
