The importance of prosthetic safety and stability

Human walking can be divided into support period and swing period from heel strike to ipsilateral heel strike again. The same is true for lower limb prostheses. The support period requires sufficient stability and can adapt to various road surfaces, and the swing period requires ease, flexibility and control at will, so as to ensure easy and safe walking and good gait.

How to achieve safe and stable walking, going up and down stairs with bare hands,

The choice of prosthetic components is critical for hip amputees. Choosing the right prosthetic hip joint is an important factor for patients to achieve a good gait. Let's take a look at the characteristics of different prosthetic hip joint .

(1) Mechanical hip joint with external extension device

 The mechanical hip joint of the external extension device can cooperate with the stable four-link knee joint and static ankle or dynamic ankle foot plate, with good joint stability, strong adjustability, and low physical energy consumption. 2-3cm on the side, it will be uncomfortable to sit for a long time.

(2) Mechanical hip joint with locking external extension device

 Mechanical hip joint with locking external extension device. Due to the addition of a locking device, the joint cannot swing when walking. It can only be released through a switch when sitting down. Calf prosthesis manufacturers, so this joint is very suitable for laborers who do heavy physical work. .

(3) Mechanical hip joint with internal extension device

  The joint body is equipped with a stepless adjustable extension aid, which is applied to the stride control, and the compression force on the spring limits the range of motion of the hip joint, so that the gait is more natural, and it also solves the prosthesis side deviation when the prosthesis is sitting. You can also put cushions and pillows on the bench to reduce the hard contact with the bench and improve the sitting comfort.
