Wrist joint passive auxiliary training device and using method thereof

Abstract

The invention discloses a passive auxiliary training device for wrist joints and a using method of the passive auxiliary training device. The passive auxiliary training device for the wrist joint comprises a motor, a transmission mechanism, an inner cylinder, a spring set and a holding rod. The transmission mechanism comprises a crankshaft, a crank, a first connecting rod, a second connecting rod, a third connecting rod, a connecting rod shaft and an outer cylinder; the inner cylinder and the outer cylinder are connected through two spring sets. The spring provides flexible support when the inner cylinder and the wrist joint of a user passively receive reciprocating swing of the outer cylinder, and the user acts on the spring of the spring set through the inner cylinder when actively training, so that force of different magnitudes is used for resisting the spring force, and swing movement of the wrist joint at different angles is achieved. The wrist joint rehabilitation training device only aims at wrist joint rehabilitation training and is flexible in movement and more effective in wrist joint healing; a user can passively receive wrist joint rehabilitation training and can also automatically twist the wrist according to the condition of the user to achieve active training, and therefore multi-angle training is achieved.

Description

Technical field [0001] The present invention belongs to the field of mechanical technology, specifically relates to a wrist joint passive auxiliary training device and a method of use thereof. Background [0002] In recent years, people's physical fitness has generally declined, and the incidence of fractures has also increased year by year. Among them, the more common one is the distal radius fracture, often accompanied by ankle and lower ankle injuries and involves the wrist joint, of which effective wrist function training has a direct impact on the distal fracture of the posterior radius and the recovery of the patient's wrist function, and will also affect the patient's postoperative quality of life. [0003] At present, wrist rehabilitation for wrist surgery and stroke patients is basically done by doctors or caregivers and has their own experience. Through the investigation, it can be seen that under normal circumstances, after 1 to 7 days after the operation, the wrist su...
