A finger function rehabilitation device with adjustable rod length

Abstract

The invention relates to a finger function rehabilitation device allowing the rod length to be adjusted. The device comprises a support used for supporting a palm of a patient waiting for rehabilitation, wherein a four-finger rehabilitation mechanism is arranged beside the support and comprises far finger baffles and near finger baffles which are all connected with a first connecting rod unit, the far finger baffles and the near finger baffles are hinged at ends, the first connecting rod unit is connected with a power mechanism, the power mechanism drives the far finger baffles and the near finger baffles to rotate relatively, the palm of the patient waiting for rehabilitation is placed on the support, four fingers are placed on the far finger baffles and the near finger baffles of the four-finger rehabilitation mechanism respectively, the first connecting rod unit and a second connecting rod unit are driven by the power mechanism to act to promote the far finger baffles and the near finger baffles of the four-finger rehabilitation mechanism to rotate relatively, bending and spreading actions of finger joints are simulated, the purpose of function rehabilitation of the four fingers of the patient is achieved, and the finger function rehabilitation device can adapt to use of rehabilitation patients with different hand shapes by adjusting the length of the near finger baffles of the four-finger 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 with adjustable rod length. 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...
