Application of carbon fiber in the field of prosthetics

1. Prosthetic foot

It is mainly used to support the weight of the human body and generate thrust during exercise. The prosthetic foot made of carbon fiber composite materials output more than 90% of the accumulated energy, which allows users to save more effort. At present, most of the high-end energy storage prosthetic foot are made of carbon fiber composite materials.

2. Carbon fiber ankle

 The linkage between the ankle and the foot of the human body plays a key role in the balance and support of the body. The ankle joint made of carbon fiber can realize the jumping function of the human body. In addition, the joint part of the ankle and the calf prosthesis can also be realized by carbon fiber, and the whole produced is very exquisite.

3. Carbon fiber knee joint

 In addition to leg injuries, knee injuries are also common. There are many kinds of materials for making this key. The steel structure is too heavy, the aluminum alloy is weak and not durable, the titanium alloy is too expensive, and carbon fiber is relatively the most cost-effective material. At present, most knee joint prostheses use a carbon fiber frame structure. This type of product is light in weight and stable in structure. When used, the joint swings smoothly and saves effort.

 4. Residual limb link cavity

The connecting part of the prosthesis and the human body is called the receiving cavity, which mainly wraps the residual limb and transmits power. This part has high load-bearing requirements and should not be too heavy. Carbon fiber materials can also be used as materials for this part. The part that contains the residual limbs can be made of polyethylene board, and the support body can be made of carbon fiber to make the frame structure to realize easy support and transfer of force.
