Knee joint orthosis with assisting knee extension and flexion

Abstract

The invention discloses a knee joint orthosis with power-assisted knee extension and flexion, which comprises an adjustable knee joint orthopedic support. Two sets of power-assisted damping devices are respectively arranged on both sides of the adjustable knee joint orthopedic support. Each set of power-assisted damping devices includes Booster leaf spring, damping bracket, leaf spring fixing block and bracket fixing block. The damping bracket is formed by connecting the leaf spring frame and the sliding rod. There is a long sliding hole in the sliding rod, and a single anti-loosening screw is fixed through the long sliding hole. on the bracket fixing block, so that the slide bar can slide and be rotatably arranged on the bracket fixing block. The knee orthosis with knee extension and flexion assistance disclosed by the present invention provides significant support force for patients with weak muscles or suffering from knee osteoarthritis when going up and down stairs, squatting, etc. It provides obvious assistance, which can prevent the risk of excessive knee flexion, strain and even fall, and is beneficial to reduce strained knee joints and 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...

AI Technical Summary

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
