Problems solved by technology

However, these knee orthopedic braces lack the power-assisted effect or the power-assisted effect is not ideal. When patients with weak muscle strength or suffering from knee osteoarthritis go up and down stairs or squat down, due to the large flexion angle of the knee joint, the patients only rely on The leg muscles cannot resist the negative work caused by the rapid fall of the body, causing the patient's knee joint to flex excessively, strain and even fall. In the long run, the knee joint is strained and the patient suffers pain
The reason is that the existing knee orthopedic brace cannot provide assistance when the patient stretches or bends the knee. Once the bending angle between the thigh strap and the calf adjustable strap changes too quickly, only the patient's own muscles Diastole or contraction, unable to stop the rapid fall of the body

Embodiment 1

[0024] Embodiment 1 provides a knee orthosis that assists knee extension and flexion, and its structure will be described in detail below.

[0025] refer to Figures 1 to 3 The knee joint orthosis with power-assisted knee extension and flexion includes an adjustable knee joint orthopedic brace 1 and two sets of power-assisted damping devices.

[0026] Wherein the adjustable knee orthopedic brace 1 is a prior art, which is available in the market, and a common adjustable knee orthosis in the market can be adopted. The adjustable knee orthopedic brace 1 includes an adjustable thigh strap 11 , an adjustable calf strap 12 , two adjustable chucks 13 , and four anti-pressure pads 14 .

[0027] The adjustable thigh strap 11 includes a first thigh frame 111, a second thigh frame 112 for binding on the thighs, and two thighs that are respectively fixedly connected to the first thigh frame 111 and the second thigh frame 112. Branch 113. The calf adjustable strap 12 includes a first c...

Abstract

The invention discloses a knee joint orthosis for assisting in knee stretching and bending. The knee joint orthosis comprises an adjustable knee joint orthopedic brace; two sets of power-assisted damping devices are arranged on two sides of the adjustable knee joint orthopedic brace respectively; each set of power-assisted damping device comprises a power-assisted plate spring, a damping support,a plate spring fixing block and a support fixing block; each damping support is formed by butt joint of a plate spring frame and a sliding rod; a long-strip-shaped sliding hole is formed in each sliding rod; and a single anti-disengagement screw penetrates through the corresponding long-strip-shaped sliding hole to be fixed to the support fixing block, so that the corresponding sliding rod can bearranged on the support fixing block in a slidable and rotatable mode. The knee joint orthosis for assisting in knee stretching and bending disclosed by the invention provides remarkable supporting force for patients with weak muscle strength or knee osteoarthritis in large-angle knee bending of going upstairs and downstairs, squatting and the like and provides obvious assisting force during kneestretching, so that the risk that the knee joint is excessively bent, strained and even falls down can be prevented, and knee joint strain is favorably reduced to relieve pain.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a knee orthosis capable of providing assistance during knee extension and knee flexion. Background technique [0002] Knee joint orthopedic brace is a common auxiliary device for knee joint rehabilitation. It includes thigh straps and calf adjustable straps worn on human thighs and calves respectively. Its function is to limit the extension and flexion of the knee joint to a suitable within the angle range, or maintain the knee joint at a certain angle, so as to promote the early recovery of knee joint function. [0003] Common knee orthopedic braces currently on the market mainly support and stabilize the patient's damaged knee joint. However, these knee orthopedic braces lack the power-assisted effect or the power-assisted effect is not ideal. When patients with weak muscle strength or suffering from knee osteoarthritis go up and down stairs or squat down, due to the lar...
