Technical Field
[0001] The utility model relates to the technical field of rehabilitation medical machinery, in particular to an exoskeleton type human upper limb rehabilitation device. Background Art
[0002] At present, stroke has become the second leading cause of death and the third leading cause of disability in the world. The risk of stroke in my country ranks first in the world. It is an acute cardiovascular and cerebrovascular disease that is very common in my country. The overall incidence and prevalence of stroke in my country are still on the rise, and the burden of stroke disease is still increasing. After suffering from a stroke, patients who survive after treatment will have sequelae of varying degrees, mainly manifested as hemiplegia, facial paralysis, visual impairment, language impairment and other symptoms that make patients lose their ability to move and live independently. More than two-thirds of patients have limb hemiplegia. Patients with hemiplegia sequelae will cause limb motor dysfunction, and they will be unable to take care of themselves to a large extent in life and cannot engage in various jobs, which will bring a great burden to the patient's family living standards and social production. Therefore, the treatment and rehabilitation of patients with hemiplegia after stroke is extremely important and urgent. The earlier the rehabilitation training of stroke patients is intervened, the greater the possibility of limb rehabilitation. Medical research results also prove this point: early, timely, scientific and effective rehabilitation exercise training for patients' affected limbs will help restore the control of the brain's central nervous system over limb motor function. Therefore, there is an urgent need for an exoskeleton-type upper limb rehabilitation device. An upper limb rehabilitation device with low cost, high rehabilitation efficiency, and multi-scenario application has important research value and practical significance. Utility Model Content

The wrist movement motor 41 drives the wrist movement gear 54 to rotate, thereby driving the wrist to flex and extend.
[0071] When patients are undergoing rehabilitation training, they can adjust the height and length of the shoulder movement mechanism, the first upper arm connecting rod 28, the second upper arm connecting rod 29, the first forearm connecting rod 38, and the second forearm connecting rod 40 according to their own height and upper limb length to meet different joint coupling length requirements and match their own training.
[0072] The entire exoskeleton upper limb rehabilitation device of the utility model uses aluminum as the main material, which reduces the weight of the entire device while meeting the strength requirements.
