Spatial mechanism-based finger function rehabilitation device

Abstract

The invention relates to a spatial mechanism-based finger function rehabilitation device. The spatial mechanism-based finger function rehabilitation device comprises a bracket which is used for supporting a palm of a patient to be rehabilitated; a thumb rehabilitation mechanism is arranged beside the bracket, and 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 connecting rod unit; the plate end of the thumb far finger baffle is hinged to the plate end of the thumb near finger baffle; a driving mechanism drives the thumb far finger baffle and the thumb near finger baffle to rotate relatively; a thumb is placed on the thumb far finger baffle and the thumb near finger baffle of the thumb rehabilitation mechanism; the thumb rehabilitation mechanism drives the connecting rod unit to act through the driving mechanism to link the thumb far finger baffle and the thumb near finger baffle of the thumb rehabilitation mechanism to rotate relatively, so that the folding and unfolding actions of a thumb joint are simulated to achieve the purpose of rehabilitating the function of the thumb of the patient; the spatial mechanism-based finger function rehabilitation device can adapt to the use of patients with different hand shapes by adjusting the length of the thumb near finger baffle of the thumb rehabilitation mechanism.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training equipment, in particular to a finger function rehabilitation device based on a space mechanism. 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...

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
