Lower limb rehabilitation robot

Abstract

The invention relates to the technical field of rehabilitation medical instruments, in particular to a lower limb rehabilitation robot, which is provided with a bracket and a treadmill, and is characterized in that the bracket is provided with a parallel buffer mechanism and a leg tralvel assisting mechanism,the parallel buffer mechanism consists of four connecting rods and a back plate. The leg travel assisting mechanism is arranged on the front surface of the back plate; the leg travel assisting mechanism consists of a group of width adjusting components, two groups of leg travel assisting components and four groups of driving adjusting components; the width adjusting component consists of a support, an tooth-reversed screw rod, a sliding seat plate and a hand wheel; the leg travel assisting component consists of a transverse hip rod and a vertical swing rod; the driving adjusting component consists of a support plate, a servo motor, a belt, a driving wheel, a driven wheel, a sleeve,a sleeve rod, a ball screw rod and a mounting hinge head. The treadmill is arranged below the leg travel assisting mechanism to assist the patient in performing ankle rehabilitation training, and therobot has the advantages of simple structure, low cost, convenient use, high popularity, and convenient household use.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a lower limb rehabilitation robot with simple structure, low cost, convenient use, high popularity rate and convenient home use. Background technique [0002] As we all know, due to the influence of acquired factors such as traffic accidents, sports injuries and various diseases caused by the aging population, the number of patients with motor impairment is increasing. Hemiplegia or paraplegia not only affects the daily life of patients, but also causes patients to suffer great psychological trauma. , seriously affecting the physical and mental health of patients. At present, there are two methods of rehabilitation training to help the affected limb recover its motion ability: traditional doctor-assisted therapy and rehabilitation training robot-assisted therapy.

AI Technical Summary

Problems solved by technology

At present, there are two methods of rehabilitation training to help the affected limb recover its motion ability: traditional doctor-assisted therapy and rehabilitation training robot-assisted therapy. Among them, medical doctor-assisted training is usually to make the affected limb Do some basic movements, but the number of rehabilitation physicians is limited and the work intensity of rehabilitation physicians is high, so the efficiency of rehabilitation training is low, and the treatment effect depends on the skill level and treatment experience of rehabilitation physicians, so traditional physician-assisted treatment cannot widely used

[0003] An effective way to solve the above contradictions is to use lower limb rehabilitation robots instead of rehabilitation doctors to carry out rehabilitation training for patients, so as to improve the efficiency of rehabilitation training and the effect of rehabilitation treatment. Due to the difficulty of developing technology and high cost, lower limb rehabilitation robots have not been widely used. Applications

Most of the products that have been formed on the market are complex in structure, occupy a large area, complex in control, and expensive. Therefore, only a small number of large hospitals with financial strength will be equipped with rehabilitation robots. The penetration rate is low and cannot benefit the public.
