H-40C Four-axis Pneumatic Knee
 Item No.: H-40C Description： The H-40C knee joint is a combined four-axis knee joint. Its multi-axis feature enables it to have translation and rotation characteristics at the same time, so it is closer to the kinematic characteristics of the human knee joint. Fitting this type of knee joint allows the patient to achieve a good gait. When the knee joint is straightened, the center of rotation is above the joint and behind the load-bearing line, thus ensuring the stability of the knee joint. On the other hand, the position of the quadrangular pyramid on the upper link can be adjusted to find the balance point of stability and flexibility of the knee joint to meet the patient's best gait requirements. Technical Parameters: Structure height: 211 mm. Structure width: 58 mm. Adjustment amount of small square pyramid: 5mm. Air valve adjustment: 3 mm. (The air valve is in the maximum opening state when it rotates counterclockwise for 3 turns from sealing the airway.) The overall weight of the knee joint: 878g. Maximum patient weight: 100kg. Knee flexion angle: 142º. (When stretching, the plane of the pyramid is 87° to the vertical plane, and when the knees are bent, the plane of the pyramid is 55° to the vertical plane.) Main Features: When the knee joint is flexed, the center of rotation drops sharply with the flexion and returns to the normal knee axis position, which is beneficial to the patient's kicking movement. After the lowest point, the knee will remain flexed and the patient can remain seated. This knee joint can adjust the speed of extension and flexion, which is helpful for patients to choose the best walking gait. |
