2021 China New Design Adjustable Elbow Orthosis - Double Axis Hydraulic Knee Joint – Wonderfu

Advantages of dual hydraulic elastic flexion insurance knee joint:

1. Safe and comfortable during the support period

EBS is the abbreviation of “Elastic Knee Bending Insurance”. After the heel hits the ground, the knee joint can bend to a position of up to 15° in a moderately elastic manner like a normal knee. The patient can walk easily, and the safety of the knee joint is improved. This also enables patients to walk more freely on uneven roads and gentle slopes, which is unique in multi-axis knee joints. The gait will look smoother and closer to the natural way. Because the physical movement is more normal, the pressure on the residual limbs, hip joints and spine is alleviated at the same time. Greatly reduce subsequent damage. When standing for a long time with a prosthesis, the advantages of EBS function are also obvious.

2. Flexible swing period

You can’t run while wearing it, but it brings excellent flexibility to prosthetics wearers of sports level 2 or 3. Whether it is stopping to buy something before the store closes, or strolling leisurely for a long time, the multi-axis knee joint can be used. Make patients take different walking speeds. In addition, it is particularly easy to take every step. This is achieved through an innovative hydraulic system that controls the behavior of the knee joint during the swing period. The damping value is determined based on the gait analysis research. Due to the multi-axis structure, the patient can obtain greater ground clearance during the swing phase, so the prosthetic leg can swing forward without hindrance.
3. Very comfortable to wear

In the new generation of EBS knee joint, we have further improved the structure of this joint. This product is more compact and weighs only 845 grams, which is also lighter than the previous generation. This also helps to improve comfort and safety.

The joint can use four modular joints, so it can adapt to various amputation heights.
