Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] In the description of the embodiment of the present invention, it needs to be stated that: when the finger rehabilitation robot is worn on the human hand, the direction where the finger points is forward, the direction where the palm is located is the back, the side where the little finger is located is left, and the side where the thumb is located is right , the back side of the palm is the upper side, and the palm side is the lower side, the embodiment of the present invention Figure 1-Figure 7 The hand model 7 is used to replace the patient's hand.

[0029] like Figure 1-Figure 7 The shown specific embodiment of a flexible four-finger rehabilitat...

Abstract

The invention belongs to the field of exoskeleton rehabilitation, and particularly relates to a flexible four-finger rehabilitation robot capable of being driven remotely. The robot comprises a hand palm-back fixing assembly, a first finger mechanism and a second finger mechanism; wherein the index finger and the little finger of a patient wear the first finger mechanisms, and the middle finger and the ring finger wear the second finger mechanisms; a remote driving device comprises a driving motor, a lead screw, a nut, a first sliding block and a push-pull wire; and the phalanx fingerstall is fixed on a finger of a patient through a first bandage. The driving motor drives the lead screw to rotate to enable the nut to move front and back, so that the push-pull wire slides forwards / backwards to control inward contraction / outward expansion and buckling / stretching training of fingers, the control is simple and convenient, and multi-degree-of-freedom training can be achieved. According to the invention, a remote driving mode is adopted, the weight of hand wearing can be reduced, and rehabilitation training of a patient is facilitated; one rehabilitation robot can train the left hand and the right hand of a patient, the cost is saved, and the space is saved.

Description

technical field [0001] The invention belongs to the technical field of exoskeleton rehabilitation, in particular to a flexible four-finger rehabilitation robot capable of remote driving. Background technique [0002] Human hands can not only carry out rough and heavy activities such as lifting, lifting, knocking and pushing, but also perform fine and complex movements such as threading and paper-cutting. Hands are the most intensive and frequently used parts. On average, hundreds or Thousands of actions such as bending, stretching and grasping. With the aging population in our country, the number of patients with stroke and hemiplegia is gradually increasing. Such diseases can lead to hand muscle atrophy. The loss of hand motor function will bring great inconvenience to people's life and work, and also bring burden to family and society. For patients with loss of hand motor ability, in addition to necessary surgery and drug treatment, it is necessary to carry out rehabilita...
