Wearable walking aid for patients with lower extremity osteoarthritis

Abstract

The invention provides a wearable walking aid for lower limb osteoarthrosis patients. The wearable walking aid for the lower limb osteoarthrosis patients comprises an upper body supporting part, thigh supporting mechanisms, shank supporting mechanisms, shoe sole supporting structures and a joint hinge rotating control device. The wearable walking aid is designed according to characteristics of the osteoarthrosis patients and is worn by one patient, joint stress is shared by a mechanical device, but joint rotation is mainly driven by the muscles of the patient, and a steel wire rope and pulley system can be supplemented to convert force that the patient treads the ground into required torque of longitudinal movement of the knees and the hip. The wearable walking aid for the lower limb osteoarthrosis patients has the advantages that the wearable walking aid needs no electricity, is low in cost and simple and convenient to use, frees two hands of the patients to enable the patients to move freely and can be used bilaterally or unilaterally according to disease states; supporting of the walking aid can share most weight of one human body borne by lower limb joints originally, and accordingly pain is relieved, the muscles can be exercised and muscle atrophy resulting from long-term lack of exercise is prevented.

Description

technical field [0001] The invention relates to a wearable walker for patients with lower limb osteoarthritis. Background technique [0002] Patients with lower extremity osteoarthritis suffer from articular cartilage lesions, and joint stress during walking will lead to pain and aggravation of the condition. Long-term asymmetric wear and tear of joints in patients with knee arthrosis will also lead to x-shaped legs and o-shaped legs. Although many countries are developing wearable exoskeletons and paying attention to intelligent control, the technology is too complicated, the cost is too high, and it is difficult to promote. There is no ideal wearable exoskeleton that is easy to use and intelligently controlled by humans in the world. At present, patients with lower extremity osteoarthritis at home and abroad still use hand-push walkers or various types of crutches. Not only the load sharing is small and it is difficult to achieve the desired effect, but also the long-term ...

Problems solved by technology

Although many countries are developing wearable exoskeletons and paying attention to intelligent control, the technology is too complicated, the cost is too high, and it is difficult to promote. There is no ideal wearable exoskeleton that is easy to use and intelligently controlled by humans in the world.

At present, patients with lower extremity osteoarthritis at home and abroad still use hand-push walkers or various types of crutches. Not only the load sharing is small, it is difficult to achieve the desired effect, but also the long-term excessive force on the upper limbs may lead to new lesions
