Robot for conservative treatment of gonitis

Abstract

The invention discloses a robot for conservative treatment of gonitis. The robot comprises a U-shaped thigh positioning groove, an ankle clamping mechanism and a periodic stretching mechanism, wherein the thigh of a patient suffering from gonitis is fixed in the thigh positioning groove, the ankle clamping mechanism clamps the ankle of the patient suffering from gonitis, and the periodic stretching mechanism is mounted between the thigh positioning groove and the ankle clamping mechanism, and is used for periodically stretching the legs of the patient and resetting the affected legs by virtue of self elasticity. The leg of a patient is periodically stretched and the affected leg is reset by virtue of self elasticity, so that the stress of the knee joint and the process that joint fluid flows into a joint capsule during repeated leg swinging are simulated, the growth of cartilage in the joint can be effectively promoted, and the treatment effect of knee osteoarthritis is ensured; and the patient does not need to stand in the treatment process, the risks of knee joint abrasion, patient falling and the like can be avoided, and the use requirements of all knee osteoarthritis patients can be met.

Description

technical field [0001] The invention relates to a conservative treatment robot for knee arthritis, which can promote the repair of knee articular cartilage and the correction of force lines of lower limbs, and belongs to the technical field of medical devices. Background technique [0002] Knee osteoarthritis is a common disease with cartilage degeneration as the main pathological change. Articular cartilage is a special connective tissue without blood vessels, lymphatic vessels and nerves. Its nutrition mainly comes from the synovial fluid in the joint. Therefore, it is generally difficult to repair the articular cartilage after it is damaged. [0003] In addition, the knee joint is prone to degeneration of the articular cartilage and meniscus of the medial compartment due to the slight deviation of the line of force of the lower limbs to the medial compartment, and gradually results in narrowing of the medial joint space, genu varus deformity, and severe cases accompanied ...

AI Technical Summary

Problems solved by technology

But there are two disadvantages in this method: 1. The patient can only swing one leg at a time, and the other leg will inevitably increase its load and accelerate the wear and tear of the knee joint due to the independent support of the whole body, which is not conducive to the growth of cartilage and the knee joint. Joint Osteoarthritis Rehabilitation

2. In order to fully swing the free leg and prevent the foot from rubbing and hitting the ground, the foot of the standing leg needs to step on an object of a certain height, which increases the risk of the patient falling, thus limiting the scope of application of this method

However, the existing corrective devices mainly perform unidirectional stretching and traction on the legs, or bind and shape the joint area. Such rigid operations can easily cause muscle congestion, plastic deformation of ligaments, and reduced mobility. It is not advocated by medicine and joint clinical science, and the principle of joint shaping is controversial in the academic circle. It is believed that wearing it for a long time will cause a certain degree of damage to the soft tissue of the patient's joint, and even have an opposite effect on the recovery of the patient.
