Variable cross section prosthetic foot with carbon spheres |
摘要 |
A dynamic prosthetic foot having variable cross section density. An ankle part diverges upwardly from a sole along a transverse parting line and includes a vertical part. A longitudinally extending slot divides the vertical part into a lateral pylon support and a medial pylon support. A lateral pylon connector is secured to the lateral pylon support and a medial pylon connector is secured to the medial pylon support. A second embodiment eliminates the pylon connectors and the lateral and medial pylon supports are elongated to provide lateral and medial pylons. High rigidity areas of the foot are formed of a high strength outer layer made with carbon reinforced composite and an inner layer made of a matrix within which is dispersed a plurality of low density hollow spheres. High stress areas of the foot are formed of carbon-reinforced composite throughout.
