Knee joint depressurizing mechanism

Abstract

The invention provides a knee joint depressurizing mechanism which comprises thigh supports, shank supports, and binding belts and lock catches fixed to the two sides of the thigh support and the shank support. The first thigh support, the second thigh support, the first shank support and the second shank support are each provided with a protecting cushion through sewing. Two bases are symmetrically and fixedly riveted on each protecting cushion. The two sides of the first thigh support and the second thigh support are connected through two parallel telescopic rods, and the two sides of the first shank support and the second shank support are connected through two parallel telescopic rods. The two ends of each telescopic rod are connected with the corresponding bases on the corresponding supports on the two sides in a threaded mode. The two sides of the outer walls of the second thigh support and the first shank support are fixedly provided with rigid thigh connecting components and rigid shank connecting components in an extending mode respectively. The thigh connecting components are movably connected with the shank connecting components. The knee joint depressurizing mechanism is comfortable and convenient to wear and adjustable in drawing force, and in the knee joint bending and stretching process, joint space can be enlarged, joint pressure can be reduced and joint wear can be reduced.

Description

technical field [0001] The invention relates to a knee joint treatment and rehabilitation device, in particular to a knee joint decompression mechanism. Background technique [0002] The knee joint is the largest and most complex joint in the human body. It bears a lot of weight and does a lot of exercise. It is the hub of lower limb activities, so its incidence rate ranks first among all joints. Among them, knee osteoarthritis is a disease with high incidence in middle-aged and elderly people. Studies have shown that excessive joint pressure is one of the main reasons for inducing or accelerating articular cartilage wear, meniscus injury, tibial plateau fracture, and avascular necrosis of the tibial node. , and joint loosening can reduce joint pressure, avoid aggravating the shearing and wear of joint soft tissue, and provide space and environment for the self-repair of soft tissue in the joint cavity, so reducing joint pressure and increasing joint space is the key to the ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that it can only be stretched during stretching, but studies have shown that during knee flexion, as the knee flexion angle increases, the gap will also decrease

In addition, due to the limitation of the size of the knee joint and the length of the thigh, the stroke is limited. When the non-working angle of the knee joint exceeds 90°, the thigh support will also be pushed up, affecting the normal flexion of the wearer, and the coupling with the human body is poor.
