Abstract

The invention relates to the mechanical field. Spatial crank-slider mechanisms are utilized for adjusting motion displacements of sliders to meet hand muscle rehabilitation requirements. A hand muscle rehabilitation device is characterized by comprising a motor, a crank, a small forefinger crank, a base board, knuckle bearings, connection rods, sliders, a finger-to-finger moving portion and a four-finger moving portion. The motor is arranged on a motor base and connected with the crank through the base board, the other end of the crank is connected with the small forefinger crank, the connection rods are placed on the base board, the crank and the connection rods and the connection rods and the sliders are connected through the knuckle bearings, and the four-finger moving portion is arranged on the sliders. The four-finger moving portion and the finger-to-finger moving portion use the spatial crank-slider mechanisms connected in parallel, and accordingly, the motion displacements of the sliders can be adjusted effectively to meet hand muscle rehabilitation requirements.

Description

technical field [0001] The invention relates to a mechanical structure, in particular to a medical device. Background technique [0002] Stroke is a prominent clinical manifestation of cerebrovascular disease. It often has sequelae such as limb dysfunction, paralysis, and aphasia, which brings great pain to patients and a great burden to family members and society. [0003] Modern medical research has shown that by increasing motor function training, the afferent impulse of receptors can be increased, the plasticity of brain function can be promoted, and the lost function can be restored. For example, use rehabilitation equipment to drive the patient's fingers to perform some specific actions, such as grasping, finger wheeling, and finger alignment. [0004] Currently, finger CPM devices on the market are generally expensive, and cannot facilitate the various activities required by hand paralyzed patients, such as grasping, wheeling, and finger-to-finger movements, and cann...
