Title (EN) PROSTHETIC KNEE WITH A RECTIFICATION HYDRAULIC SYSTEM
(FR) GENOU PROTHÉTIQUE AVEC SYSTÈME HYDRAULIQUE DE RECTIFICATION
Abstract:
(EN) Described here are prosthetic systems, devices, and methods of use therefor. Generally, a prosthesis may be configured to set a resistance to rotation of a prosthetic joint based on a phase of gait. The prosthesis may include a first cylinder, a first piston slidable within the first cylinder, a fluid sump, and a fluid circuit. The fluid circuit may include a plurality of interconnected fluid channels having a unidirectional variable-resistance valve and a set of check valves that are configured to provide unidirectional flow through the valve during piston compression and extension.
(FR) La présente invention concerne des systèmes prothétiques, des dispositifs et des procédés d’utilisation de ceux-ci. Généralement, une prothèse peut être configurée pour ajuster une résistance à la rotation d’une articulation prothétique sur la base d’une phase de marche. La prothèse peut comprendre un premier cylindre, un premier piston pouvant coulisser dans le premier cylindre, un réservoir de fluide et un circuit de fluide. Le circuit de fluide peut comprendre une pluralité de canaux de fluide interconnectés ayant une valve à résistance variable unidirectionnelle et un ensemble de clapets antiretour qui sont configurés pour produire un écoulement unidirectionnel à travers la valve pendant la compression et l’extension du piston.
