Finger function rehabilitation training device

Abstract

The invention relates to a rehabilitation training device for a finger function. The device comprises a four-finger rehabilitation mechanism and a thumb rehabilitation mechanism, which are arranged aside a bracket, wherein the four-finger rehabilitation mechanism comprises a far finger baffle and a near finger baffle; the far finger baffle and the near finger baffle are connected with a first connecting rod unit; the ends of the far finger baffle and the near finger baffle are hinged with each other; a driving mechanism is used for driving the far finger baffle and the near finger baffle to relatively rotate; the thumb rehabilitation mechanism comprises a thumb far finger baffle and a thumb near finger baffle; the thumb far finger baffle and the thumb near finger baffle are connected with a second connecting rod unit; the ends of the thumb far finger baffle and the thumb near finger baffle are hinged with each other; the far finger baffle and the near finger baffle of the four-finger rehabilitation mechanism are rotated relative to each other, the thumb far finger baffle and the thumb near finger baffle linked with the thumb rehabilitation mechanism are rotated relative to each other and the folding and unfolding action of the palm joint is simulated, so that the purpose of recovering the finger function of the patient can be achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training equipment, in particular to a finger function rehabilitation training device. Background technique [0002] Stroke is the third leading cause of death in Western industrialized countries after malignant tumors and cardiovascular diseases. In China, which accounts for one-fifth of the world's population, stroke has become the second leading cause of death. The disease rate is increasing year by year. Most of the survivors have various degrees of sequelae such as limb movement disorders and cognitive impairments. Clinically, patients with ischemic stroke suffer from hemiplegia as the main sequelae. In the rehabilitation of hemiplegia, the recovery of finger function is the most difficult. Rehabilitation during the recovery period is very important for patients with stroke sequelae. It is currently believed that patients with limb movement disorders caused by stroke can significantly...

Problems solved by technology

At present, the hand rehabilitation equipment used in the industry mainly uses surface electromyography signal triggering and dynamic intelligent control to complete interactive biofeedback training to realize the independent movement of the patient's four fingers, thumb, and wrist. However, the mechanism is complex and expensive. Lack of fine-tuning mechanism, unable to meet the exercise requirements of patients at all stages of rehabilitation
