Title
(EN) PROSTHETIC FOOT
(FR) PIED PROTHETIQUE
Abstract
(EN)
A prosthetic foot (10) includes an energy storing, upper foot member (16) movably coupled to and spaced above an energy storing, lower foot member (14). An energy transfer medium (42) is disposed between and separates the upper and lower members. The energy transfer medium has opposite, upper and lower contact surfaces (46, 48) along which the respective upper and lower members track during flexion. The energy transfer medium had a greater flexibility than the upper and lower members to allow the upper and lower members to move with respect to one another and flex, and to provide a cushion to soften the feel of the foot while allowing the upper and lower members to be stiffer. An adjustable fastener (76, 78) may couple the energy transfer medium and upper and lower members together, to selectively tighten and loosen the upper and lower members to adjust stiffness of the foot. Separate forward and rearward energy transfer mediums (154, 158) may be movably and selectively located along a longitudinal axis of the foot to adjust stiffness. The energy transfer medium may taper from the middle (90) to the lateral side (94, 96) to allow the upper and lower members to rotate about a longitudinal axis (100) of the foot to simulate ankle rotation.
(FR)
L'invention concerne un pied prothétique (10) constitué d'un élément supérieur (16) emmagasinant l'énergie couplé amovible à un élément inférieur (14) emmagasinant l'énergie et placé, de façon espacée, au-dessus de celui-ci. Un milieu de transfert d'énergie (42) est disposé entre lesdits éléments supérieur et inférieur, de manière à les séparer. Le milieu de transfert d'énergie possède des surfaces de contact supérieure et inférieure (46, 48) opposées, le long desquelles se déplacent respectivement les éléments supérieur et inférieur au cours de la flexion. Le milieu de transfert d'énergie est bien plus souple que les éléments supérieur et inférieur, d'une part, pour permettre auxdits éléments supérieur et inférieur de se déplacer l'un par rapport à l'autre et de fléchir, et d'autre part, pour constituer un coussin destiné à assouplir le pied et à permettre dans le même temps aux éléments supérieur et inférieur d'être plus rigides. Un élément d'attache réglable (76, 78) permet de coupler le milieu de transfert d'énergie et les éléments supérieur et inférieur, de manière à raidir et à détendre sélectivement les éléments supérieur et inférieur pour régler la rigidité du pied. Des milieux de transfert d'énergie avant et arrière (154, 158) séparés peuvent être disposés de façon mobile et sélective le long d'un axe longitudinal du pied pour régler sa rigidité. Le milieu de transfert d'énergie peut diminuer en épaisseur entre son milieu (90) et ses côtés (94, 96) afin de permettre aux éléments supérieur et inférieur de tourner autour d'un axe longitudinal (100) du pied, et de simuler ainsi la rotation de la cheville.
