Description

technical field

[0001] The invention relates to a multi-degree-of-freedom thumb rehabilitation training device for hemiplegic patients, belonging to the technical field of medical devices. Background technique

[0002] "Stroke" (cerebralstroke), commonly known as "stroke" or "cerebrovascular accident" (cerebralvascularaccident, CVA), is an acute cerebrovascular disease. It is a group of diseases that cause brain tissue damage due to sudden rupture of blood vessels in the brain or blockage of blood vessels that prevents blood from flowing into the brain. It is the leading cause of disability in Chinese adults, and severe cases can cause death. By investigating the medical records of "stroke" patients in major hospitals, it can be found that even if the patients can survive, a large part of them still have disabilities, especially the sequelae of hand disabilities. The hand is a complex and very flexible part of the human body. In daily life, the hand is an indispensable tool...

Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection claimed by the present invention is not limited thereto.

[0018] Such as Figure 1~3 As shown, the present invention is used for the multi-degree-of-freedom thumb rehabilitation training device for hemiplegic patients, including a support base 23 and a driving sensing mechanism I and a driving sensing mechanism II fixed on the supporting base 23, and a driving sensing mechanism I and a driving sensing mechanism. The sensing mechanisms II are arranged vertically to each other, and the driving sensing mechanism I and the driving sensing mechanism II are sequentially composed of a coaxial photoelectric encoder 18, a DC torque motor 19, a shaft coupling 20, a magneto-rheological fluid damper 21, and a torque sensor. sensor 22; where one end of the DC torque motor 19 is connected to the photoelectric encoder 18, the othe...
