Title (EN) CONTROLLABLE TRANSVERSE ROTATION ADAPTOR
(FR) ADAPTATEUR DE ROTATION TRANSVERSALE APTE À ÊTRE COMMANDÉ
Abstract:
(EN) Torsional loads can impart painful and potentially injurious shear stresses upon residual limb soft tissues in lower limb amputees. To protect the soft tissues, a controllable transverse rotation adapter (TRA) has been developed that permits rotation of the prosthetic socket relative to the prosthetic foot, relieving some of the rotational loads experienced by the residual limb, and controlling either the stiffness resisting the transverse rotational torque, or the torque. This TRA uses series elastic actuator (SEA) technology and includes a prime mover, a speed reduction device, and a torsion spring mounted in series. By measuring a displacement of the spring (e.g., using a strain gauge), motor current, and the motor shaft position, the load torque and position can be used to calculate actual stiffness or applied torque. The motor position is then adjusted relative to the load, to control the effective stiffness or torque.
(FR) Des charges de torsion peuvent communiquer des contraintes de cisaillement douloureuses et potentiellement nuisibles dans des tissus mous de membre résiduels chez des personnes amputées des membres inférieurs. Selon l'invention, pour protéger les tissus mous, un adaptateur de rotation transversale apte à être commandé (TRA) a été développé, lequel permet une rotation de l'emboîture de prothèse par rapport au pied de prothèse, libérant certaines des charges de rotation subies par le membre résiduel, et commandant soit la rigidité résistant au couple de rotation transversale, soit le couple. Cet adaptateur de rotation transversale utilise une technologie d'actionneur élastique en série (SEA) et comprend un appareil moteur, un dispositif de réduction de vitesse, et un ressort de torsion monté en série. Par la mesure d'un déplacement du ressort (par exemple, à l'aide d'une jauge extensiométrique), d'un courant moteur, et de la position de l'arbre moteur, le couple de charge et la position peuvent être utilisés pour calculer une rigidité réelle ou un couple appliqué. La position du moteur est ensuite réglée par rapport à la charge, pour commander la rigidité ou le couple réels.
