While causing a different force effect on different joints, reducing latency relative to custom orthotics. While for patients who want to use different orthotics at different times, the cost of consumption is saved. The main functions are as follows: increase joint activity degree, the putting of function position and rest position, compensate the muscle function, reduce muscular tension and restrain the spasm, prevent and correct the deformity, resist the function training, restriction range of motion.
This device can change elastic support's elastic force's joint according to the injured condition of different patients, and application scope is wider. The elastic supports under a plurality of different conditions can be prestored in the device, and the device can be applied to patients only by selecting different elastic supports according to the conditions of the patients, so that the time is saved compared with a customized orthosis.

When in use:
the functional position and the rest position are placed: when repairing injured muscles and adjusting tendon tension, the hand should be adjusted to rest position: the elastic support of the wrist joint is adjusted to enable the wrist joint back to extend 10 degrees to 15 degrees and slightly deflect the ulna (the elastic support slightly deflects towards the inner side). The degree of flexion of the metacarpophalangeal joint and interphalangeal joints is adjusted to be in the semi-flexion position, the degree of flexion is gradually increased from the index finger to the small finger, and the finger tip points to the scaphoid tubercle. The external inclination of the thumb elastic support is slightly extended, and the finger pulp approaches or touches the radial side of the distal interphalangeal joint of the index finger. When the trauma dressing is fixed, the functional position of the hand is adjusted: the elastic support is selected to ensure that the curvature of each joint is 25-30 degrees of dorsum extension of the wrist, the thumb is fully abducted, the metacarpal joint and the interphalangeal joint are slightly bent, and the fingers are separated.
Increase the joint mobility: the high-elasticity elastic support is used to play a role of a dynamic orthosis, and the elasticity of the high-elasticity support is used to continuously and passively draft the joint with limited joint mobility caused by contracture and adhesion, so that the joint mobility of the joint can be increased.
Compensatory or auxiliary muscle function: if the muscle strength of the extensor digitorum is weakened, the curvature of the elastic plastic can be increased, the extensor digitorum is in an automatic buckling state when being relaxed, the gripping capability is realized, the function of the extensor digitorum is not limited at this time, and after the extensor digitorum resists the elastic plastic to stretch fingers, the purpose of gripping objects by the loosened fingers can be realized, and then the next step of gripping can be carried out. The elastic force of the elastic support is used for assisting the muscle function activities, so that the limbs can be promoted to complete daily life activities and functional activities, and the nerve recovery is promoted.
Reduction of muscle tone and inhibition of spasticity: for example, in stroke brunnstrom, functional grade III, the hand should be held in an anti-flexospasm position to reduce the hand flexor tension and induce extensor muscle extension. The force effect of the elastic plastic in the direction of straightening the hand is increased at this time. The gentle and continuous stretching action on the flexors of the hand can reduce muscle tension and inhibit muscle spasm.
Prevention and correction of deformities: the curvature of the elastic support or the slope of the left-right deflection can be increased to prevent and correct the deformity of the hand. According to the recovery conditions of different periods, the curvature or the inclination of left and right deflection of the elastic plastic is gradually adjusted to adjust the acting force on the joint in different periods.
And (3) resistance function training: when the flexion degree of the elastic support is increased, the resistance to the straightening muscle group can be increased to play a role in resisting the muscle strength training of the straightening muscle group, and the resistance application degree of the elastic support can be gradually increased according to the recovery condition of a patient.
Limiting the moving range: the movement range of the dynamic orthosis is set within a certain range by adjusting the flexion degree of the elastic plastic, for example, the movement degree of the wrist joint is limited within the range of 30-80 degrees of flexion by adjusting the elastic bracket of the wrist joint in the early stage after the median nerve injury repair of the forearm, and the flexion angle is not allowed to be less than 30 degrees and the dorsal extension is not allowed.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
