Product Introduction:

The H-30B knee joint is a combination multi axis knee joint, whose multi axis characteristics allow it to have both translational and rotational features, making it closer to the motion characteristics of the human knee joint. Installing this knee joint is convenient for users to achieve a good gait.

When the knee joint flexes, the center of rotation rapidly decreases with the flexion and returns to the usual knee axis position, which is beneficial for the user's leg flexion movement. When crossing the lowest point, the knee joint will remain flexed, allowing the user to maintain a sitting position.

This joint adopts a geometric lock function during the support period in its design, greatly improving the stability of the joint during support and meeting the needs of users with high stability requirements. On the other hand, by adjusting the position of the four sided pyramid on the upper connecting rod, the stability and flexibility balance point of the knee joint can be found to meet the user's optimal gait requirements.

The joint is made of high-strength aluminum magnesium alloy material, which has the advantages of high strength and light weight. The cylinder body adopts a swinging method, with less wear and longer service life than a fixed cylinder pneumatic knee joint.

The design of a large knee flexion angle provides users with better convenience.

This knee joint can adjust the speed of extension and flexion, which is beneficial for users to achieve the best walking gait.

This joint has been tested by a national authoritative testing institution and meets the requirements of GB17423-2008 "General Parts for Lower Limb prostheses" and GB/T 18375.5-2004 "Structural Inspection of Lower Limb prostheses Part 5: Auxiliary Structure Inspection" standards.
