Finger flexion and extension training instrument

Abstract

The present invention belongs to a rehabilitation training device and particularly relates to a finger flexion and extension training instrument. The finger flexion and extension training instrument comprises a bottom plate, a wrist strap, 5 finger fixing parts, a flexion driving device and an extension driving device for driving the finger fixing parts to move, the flexion driving device comprises a wire retracting and releasing device I arranged on an upper surface of the wrist strap, the wire retracting and releasing device I is provided with 5 driving ropes I connected to the finger fixingparts, the extension driving device comprises a wire retracting and releasing device II arranged on a bottom surface of the bottom plate or a lower surface of the wrist strap and 5 guide rings I arranged on the bottom plate located at lower ends of five fingers, the wire retracting and releasing device II is provide with 5 driving ropes II connected to the finger fixing parts, and the driving ropes II pass through the guide rings I. The flexion driving device and the extension driving device are arranged to drive the 5 finger fixing parts arranged on the five fingers of a trainer to realize flexion and extension movements of the fingers. The rehabilitation training device is simple in overall structure, convenient to wear and good in a training effect.

Description

technical field [0001] The invention belongs to a rehabilitation training device, in particular to a finger flexion and extension training instrument. Background technique [0002] The basic movements of the hand include non-grip movements and grasping movements. In a day, the hand can complete thousands of flexion and extension, finger alignment, palm alignment and grasping. The hand is one of the most important structures of the body, and most of the human's ability to use tools comes from the fine control of the hand's grasping function. [0003] The functions of the hands are delicate and complex. Once dysfunction occurs, it will seriously affect the control and coordination functions of the hands. It will be difficult or even impossible to fine motor, which will seriously affect the ability of daily life activities, such as eating, typing, driving, drawing and writing, etc. Long-term neglect or even Causes stiffness and paralysis of the hand. [0004] Hand dysfunction...

AI Technical Summary

Problems solved by technology

[0006] At present, the common finger flexion and extension exercise devices in the market are generally faced with a relatively simple structure, which can only simply perform flexion and extension exercises, and the training effect is poor, and it is extremely inconvenient to wear, the market competitiveness is small, and the practicability is not strong.
