Title (EN) PROSTHETIC FOOT AND ANKLE SYSTEM
(FR) SYSTEME DE PIED ET DE CHEVILLE PROTHETIQUE
Abstract:
(EN) A dual ankle spring foot ankle system comprising a first (30) and second (34) die helical springs attached proximally to a top ankle plate (17) and distally to a plantar base plate (25) through a helical nut (30) for helically engaging the spring around its body portion for rigid attachment of the spring to the plate themselves. The system further includes a rear positioned flexible member (22) extending from the upper plate to the bottom plate member (22) for minimizing elongation of the posterior spring beyond a certain point. There is further provided a downwardly depending forward portion (20) of the base plate for insertion into a soft foot. A second embodiment includes a stepped base plate (82).
(FR) Système de cheville de pied à double ressort de cheville comprenant un premier (30) et un second ressorts hélicoïdaux, fixés proximalement à une plaque (17) de cheville supérieure et distalement à une plaque (25) de base plantaire au moyen d'un écrou (30) hélicoïdal destiné à entrer en contact hélicoïdalement avec le ressort, autour de sa partie de corps, afin de fixer le ressort de manière rigide aux plaques elles-mêmes. Le système comprend en outre un élément (22) souple positionné à l'arrière, s'étendant à partir de la plaque supérieure jusqu'à l'élément (22) de plaque inférieure afin de réduire au minimum l'extension du ressort postérieur au-delà d'un certain point. Est également prévue une partie avant (20) de la plaque de base inclinée vers le bas, destinée à être introduite dans un pied souple. Un second mode de réalisation comprend une plaque de base (82) en gradin.
