Five-freedom-degree series-parallel lower limb rehabilitation robot

Abstract

The invention discloses a five-freedom-degree series-parallel lower limb rehabilitation robot, and belongs to the technical field of medical rehabilitation instruments. The five-freedom-degree series-parallel lower limb rehabilitation robot can achieve the attitude rotation around the X axis, the Y axis and the Z axis, conducts axial movement along the Y axis and the Z axis, and actually simulates multi-free-degree complex motions of human lower limb and foot walking. The five-freedom-degree series-parallel lower limb rehabilitation robot comprises a rack and two moving platforms, and a base and a support are connected in a series mode to form the rack. When a patient is in the early days of rehabilitation, the patient can keep balance with the help of a supporting frame and passively conduct rehabilitation trainings of lower limb joint motion. When the patient is in the later stage of rehabilitation, the patient can actively conduct the rehabilitation exercises of walking and the like with the help of handles frames, so that the rehabilitation trainings are more effectively and continuously provided for the patient. The five-freedom-degree series-parallel lower limb rehabilitation robot is comprehensive in functions, simple in structure, convenient to operate, and suitable for different training stages of different patients, so that the patient with lower limb walking function damaged can more effectively and continuously conduct the rehabilitation trainings.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation machinery, and describes a five-degree-of-freedom hybrid rehabilitation robot suitable for lower limb rehabilitation treatment, which can simulate actual rehabilitation movements such as lower limb walking and ankle movement, and can effectively realize lower limb hemiplegia and lower limb motor function damage, etc. Rehabilitation training function for patients with similar diseases. Background technique [0002] At present, my country, like many countries in the world, is gradually entering an aging society. Among the elderly, cerebrovascular and nervous system diseases occur frequently, and most of them have symptoms of hemiplegia. Simultaneously, the number of nerve injury or limb injury that causes because of traffic accident is also increasing. In particular, motor skill impairments in the lower extremities have seriously affected patients' daily life. In addition to early s...

Problems solved by technology

At present, the existing lower limb rehabilitation robots are basically active robots. For example, the Chinese patent application No. 201120422008.9 discloses a lower limb rehabilitation stepper, which adds damping pulleys. activities, but did not pay enough attention to the early recovery of patients, so it is not only difficult for patients in the early recovery to achieve the expected recovery effect, but even have adverse effects on the patient's condition
