Benefits of technology

The invention described in this patent helps align prosthetic sport feet better, which is beneficial.

Problems solved by technology

Additional holes can weaken the laminate, and in some cases the foot is scrapped.
However, the use of alignment wedges can be time-consuming because the prosthetic components must be disassembled to make adjustments.
Additionally, alignment wedges typically have pre-set angles, which can limit the range of angular adjustment possible during alignment.

Abstract

An alignment adapter for prosthetic sport feet, such as running feet, includes a male pyramid plate having a male pyramid, a female connector plate having a female connector, and a back plate. For use during alignment of a prosthetic running foot, the male pyramid plate is coupled to the back of a user's socket and the female connector plate and back plate are clamped about the foot. The male pyramid and female connector are coupled and adjusted relative to one another to achieve a desired alignment. The socket and foot are locked in an alignment fixture to maintain the alignment and the male pyramid, female connector, and back plates are removed. A laminated plate is coupled to the socket to maintain alignment during normal use.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority benefit of U.S. Provisional Application No. 61 / 665,162, filed Jun. 27, 2012, the entirety of which is hereby incorporated by reference herein and should be considered a part of this specification.BACKGROUND[0002]1. Field[0003]The present application relates to prosthetic adapters in general, and more particularly, to an alignment adapter for use with prosthetic sport feet.[0004]2. Description of the Related Art[0005]Various types of prosthetic foot devices are available as substitutes for human feet. Some prosthetic feet are designed especially for sporting activities such as running, both at the recreational and competitive levels. Prosthetic running feet are typically designed to efficiently store and release energy produced during running to improve performance. The alignment of prosthetic sport feet can affect the performance of the device and therefore the performance of the user athlete. For example,...
