Abstract

The invention discloses a disc type magnetorheological damper lower limb rehabilitation robot, and relates to the technical field of medical instruments. The disc type magnetorheological damper lowerlimb rehabilitation robot is characterized in that: two hip joint belt pulleys are respectively connected to an output end of a hip joint reducer and a lateral top of a thigh rod; a hip joint belt ismounted on the two hip joint belt pulleys and used for transmitting power of a hip joint motor to the thigh rod via the two hip joint belt pulleys; two knee joint belt pulleys are respectively connected to the output end of a knee joint reducer and the lateral top of a calf rod; and a knee joint belt is mounted on the two knee joint belt pulleys and used for transmitting the power of a knee jointmotor to the calf rod via the two knee joint belt pulleys. According to the invention, disc-type magnetorheological dampers are respectively arranged between the hip joint motor and the hip joint reducer and between the knee joint motor and the knee joint reducer, thereby realizing the control of the output torque of the motors, and solving the problem of excessive output torque of a driving motor; and moreover, an anti-resistance effect can be provided when a patient actively trains, thereby facilitating the enhancement of the rehabilitation treatment effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a robot for rehabilitation treatment of lower limbs. Background technique [0002] Rehabilitation therapy, also known as rehabilitation physical therapy, is a special therapy that can prevent, improve and recover the dysfunction and low function of the patient's body. Traditional rehabilitation procedures rely on the therapist's experience and hands-on skills. In recent years, with the rapid increase in the number of patients, reforms to save medical resources and improve the efficiency of rehabilitation treatment are imminent. [0003] Rehabilitation robot is a new type of robot that has emerged in recent years and belongs to the category of medical robots. It mainly drives the limbs to do repetitive movements through machines, stimulates and promotes the reconstruction of the nervous system that controls the movement of the limbs, and is a new type of clinical inte...
