摘要：
This invention provides new above knee (AK) and below the knee (BK) orthotic devices and implements specific manufacturing processes for the production of orthotic devices through the automated, computer controlled bi-axial and tri-axial braiding of orthotic devices, over a mold or mandrel made of carved foam, plaster material or wax that is a replica of the patients limb, and is created by a Computer Aided Design (CAD) file controlling a Numerically Controlled (CNC) machine tool. This method of manufacture using aerospace fibers such as graphite or Kevlar, and high performance resins, is used to create a orthotic device which is stronger and lighter weight than conventionally manufactured orthotic devices. Braiding also allows incorporation of woven cloth, tapes and other reinforcements into the braiding process for added strength at selected areas. The method dramatically decreases the production time and cost of the relative to conventional methods.
