Hand rehabilitation training device with wrist rehabilitation training function

Abstract

The invention discloses a device for hand rehabilitation training with the function of wrist rehabilitation training, which effectively solves the problems in the prior art that the training device is bulky and not easy to carry, and has the advantages of simple structure, easy operation and high functionality. As follows: the device includes at least one two-joint finger training mechanism and a wrist training mechanism; wherein, each two-joint finger training mechanism includes a power drive source fixed by the joint bracket of the finger near the end of the finger, and the push rod of the power drive source is connected to the finger near the end of the finger. The joint driving part is connected to control the rear joint of the human finger; the finger proximal end joint support, the finger proximal finger end joint driving part is fixed by the finger proximal finger end joint support and the finger proximal finger end joint support defines the position of the finger proximal finger end joint driving part The moving path is the far fingertip joint support of the finger, and the multi-link mechanism is connected with the finger far fingertip joint support.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a hand rehabilitation training device with wrist rehabilitation training function. Background technique [0002] Stroke is characterized by high morbidity, disability and mortality. According to the current development trend, the global death toll caused by stroke will reach 6.5 million in 2015 and 7.8 million in 2030. Stroke has the characteristics of high morbidity, high mortality and high disability rate. In my country, there are 2.5 million cases of morbidity and about 1.5 million deaths every year, and the trend continues to rise every year. Among the surviving patients, three-quarters were disabled to varying degrees, and about 40% were severely disabled. Among the numerous sequelae, numbness and spastic paralysis will occur in the limbs. These sequelae are mainly treated through exercise. Among them, the rehabilitation of limbs, especially hand functions, is the most di...

Problems solved by technology

[0003] At present, the rehabilitation manipulators used in the industry mainly use surface electromyographic signal triggering and dynamic intelligent control to realize interactive biofeedback training to realize the separate movements of the patient's four fingers, thumb and wrist; if all the devices are worn, due to the size It is relatively bulky, and if worn, it is heavy in weight, inconvenient to carry, complex in structure, and poor in mobility, which not only prolongs the rehabilitation training time of the patient, but also increases the burden on the patient. Relatively simple
