Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of novel finger rehabilitation training devices, are used as actively or passively rehabilitation training, side
Paralytic is helped to temper the expansion service in each joint of finger, so that patient's finger can take object, to solve daily life
Problem.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Embodiment 1,
The present embodiment provides parts between a kind of novel finger rehabilitation training device, including fixed part and the first finger.First
Part holding finger closely saves, after finger middle section or digital tip between finger, makes portion between fixed part and the first finger by external motivating force
Point relatively rotate, can be realized finger closely save, the passive rehabilitation training of the single finger joint such as finger middle section or digital tip；By patient
Itself movement make fixed part and first refer between partial relative rotation, can be realized finger closely save, finger middle section or digital tip
Etc. the initiative rehabilitation training of single finger joint.
The present embodiment is illustrated by taking the rehabilitation training of single joint on finger as an example, and embodiment 2 also can be used in the present invention
And the structure in embodiment 3, realize that the synchronous of multiple joints restores to take exercise.
Fixed part includes the first fixing piece 19, the first driving gear 16, the first spool 32 and the first cotton rope, and first actively
Gear 16 is rotationally connected on the first fixing piece 19, and the first spool 32 and the first driving gear 16 are coaxial and relatively fixed.First
