Hip, knee and ankle active and passive training rehabilitation apparatus based on four-bar mechanism

Abstract

A hip-knee-ankle active and passive training rehabilitation apparatus based on a four-bar mechanism comprises a hip joint driving module, a knee joint driving module, an ankle joint driving module and a base. The hip joint driving module is installed on the base, the knee joint driving module is connected with the hip joint driving module, the ankle joint driving module is installed on the knee joint driving module, the three driving modules conduct independent training on hip joints, knee joints and ankle joints respectively, and the hip joint driving module and the ankle joint driving module are each composed of a four-bar mechanism. The hip, knee and ankle joints can be independently trained, meanwhile, active training is conducted by recognizing the electromyographic signals of the lower limbs of the human body, the leg muscle strength of a patient can be better trained, and compared with a traditional motor lead screw driving mode, the four-bar mechanism is faster in response and smaller in size.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hip, knee and ankle active and passive training rehabilitation device based on a four-bar linkage mechanism. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the average life expectancy of human beings is gradually extended, and the elderly population is gradually increasing. As people grow older, human bones and joints tend to wear out due to degeneration or long-term use. This causes them to have limited mobility and joint pain. After joint injury, it can lead to joint adhesion, cartilage degeneration, joint movement dysfunction and even joint stiffness. Medical theory and clinical medicine have proved that in addition to early surgical treatment and drug treatment for such patients, correct and scientific rehabilitation training plays a very important role in the recovery and improvement o...

Problems solved by technology

[0004] In order to overcome the above technical problems, the object of the present invention is to provide a hip-knee-ankle active and passive training rehabilitation device based on a four-bar linkage mechanism, which solves the problem that traditional rehabilitation devices can only perform rehabilitation on the knee joint. Knee and ankle joints are trained, and at the same time, active training is carried out by identifying the myoelectric signals of the lower limbs of the human body, which can better train the muscle strength of the patient's legs. Compared with the traditional motor screw drive method, the four-bar linkage mechanism Faster response and smaller size
