Horizontal lower limb rehabilitation robot based on lasso driving

Abstract

The invention discloses a lasso-driven horizontal lower limb rehabilitation robot which structurally comprises a thigh assembly, a shank assembly, a waist assembly, a hip joint assembly, a knee joint assembly, an ankle joint assembly, a power device and a lying bed assembly, the waist assembly is fixedly connected with the lying bed assembly, and a left mechanical leg and a right mechanical leg are symmetrically arranged. Rehabilitation training needed clinically is provided for people with limb disability caused by joint replacement, fracture or central nervous injury, a passive training mode based on preset track traction and an active training mode based on active movement intention are included, the patient is helped to recover lower limb muscle strength and activity ability, and postoperative complications are avoided. In the rehabilitation training process, data collected by the sensors are uploaded to a PC end in real time, feedback information of the affected limbs is provided for patients and therapists, and valuable reference data is provided for making clinical diagnosis and treatment schemes. The whole machine can automatically adjust the length and the width, has various training modes, is suitable for patients with various figures and different rehabilitation degrees, and is easy to disassemble, carry and install.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a horizontal lower limb rehabilitation robot driven by a lasso. Background technique [0002] With the development of robots and electronic information technology, more and more lower extremity rehabilitation robots are used in clinical rehabilitation. This type of robot can provide high-intensity and high-repetition exercise training to help people with lower extremity walking disorders or joint replacements and fractures. Wait for patients with lower extremity diseases to carry out post-operative auxiliary rehabilitation training to restore the lower extremity muscle strength and mobility of patients, and prevent the occurrence of muscle atrophy, joint adhesion, and continuous decline in limb function and other adverse consequences. The clinical application of lower limb rehabilitation robots not only greatly relieves the work pressure of rehabilitation physicians, but ...

AI Technical Summary

Problems solved by technology

[0003] For patients at different rehabilitation stages, the lower limb rehabilitation robot is divided into three types: vertical, sitting and horizontal. The Chinese invention patent application with the publication number CN 102697622 B discloses a "sitting and lying lower limb rehabilitation robot". It is designed to realize two forms of rehabilitation training in sitting and lying positions by adjusting the seat, but each mechanical leg only has three degrees of freedom of the hip joint, knee joint and ankle joint, which greatly restricts the patient's range of motion and cannot meet the needs of rehabilitation training. required requirements

The Chinese invention patent with the publication number CN 102727361B discloses a "sitting and lying lower limb rehabilitation robot". The effect of rehabilitation training, but this form makes the joints of the exoskeleton bulky, and the weight and moment of inertia are very large, which causes inconvenience to the wearing and control process. At the same time, it is difficult for patients to use and it is easy to cause safety problems.
