prosthetics legs

Because the typical prosthetic leg is designed to resemble a real limb, few of us take the time to wonder about the parts of a prosthetic leg. But understanding how the individual parts work will help you understand why they function so well together. That understanding is crucial for living with a prosthetic leg, whether it is for yourself or when you are helping a loved one incorporate the new limb into his or her life.

Artificial limbs are the means and methods of engineering technology to make up for amputees or limbs with incomplete defects, and specially designed and fabricated artificial prostheses, also known as "prosthetic limbs". Its main role is to replace the lost part of the limb function, the amputees to restore some of the daily life and work ability. The application object is due to illness, traffic accidents, accidents, sports injuries and other reasons ".

The classification of artificial limbs. Artificial limbs can be classified according to structure, function, assembly time, amputation position, power source and material selection. But the most commonly used classification method is to divide the upper limb prosthesis and lower limb prosthesis according to the amputation site.

Following are some of the most common types of prostheses:

Lower leg and foot. A number of prosthetic feet are available to simulate the action of a natural foot after an amputation below the knee. At least one available foot-ankle prosthesis is controlled by a microprocessor. It uses feedback from sensors to adjust joint movement, making walking more efficient and reducing the risk of falls.

Leg with knee. For amputations above the knee, the prosthesis has both a knee and ankle joint. Currently there are more than 100 prosthetic ankle, foot, and knee models. Some use fluid or hydraulic-controlled devices that let users vary their walking speed. Others use computerized parts that let the user make rapid real-time adjustments while walking.
