Description

Button-type dial device {BUTTON TYPE DIAL APPARATUS}

The present invention relates to a button-type dial device, and in particular, to allow a scoliosis patient who has difficulty in wearing compression, to easily press and release after wearing orthodontic clothing, and also to adjust a portion of the orthodontic region by adjusting the elasticity of the band after wearing orthodontic clothing. It relates to a button-type dial device that is easy to press overall.

The spine is the bone that keeps the main skeleton from human to neck, back, waist, buttocks and tailbone.

Specifically, the spine is divided into 7 neck bones (cervical vertebrae), 12 breast bones (thoracic vertebrae), 5 lumbar vertebrae (lumbar vertebrae), 5 sacral bones (sacrum), and 4 tailbones (vertebrae).

On the other hand, the spinal cord exists in the spine as a nerve bundle from the brain, which serves to connect the brain, the central nervous system, and peripheral organs, the peripheral nervous system.

As mentioned above, the spine is a very important part of the body, and it causes a lot of difficulties for people with spinal diseases.

Typical spinal diseases include cervical spinal disc dislocation, scoliosis, low back pain syndrome, and intervertebral disc prolapse.

Particularly, scoliosis is one of the representative spinal deformations, and there is a'curve' in the human spine, meaning'curved' or'bent'. There is an abnormal curvature that cannot be seen.

Such scoliosis occurs in a growing period, with about half of all scoliosis patients being teenagers.

Different measures should be taken depending on the degree of scoliosis, but the cases are often exacerbated due to the fact that the symptoms are not recognized or simple observational measures are often taken.

Therefore, the purpose of the treatment of scoliosis is to prevent the curvature of the hardness from further progressing, and the curvature of the severity or more corrects the malformation and maintains the correction to improve the body's balance to improve function and beauty.

If scoliosis is found early, conservative methods, such as wearing an appropriate brace, can prevent the progression to severe curvature.

However, the conventional assistive device has a problem in that it cannot effectively respond according to the degree of deformation of the scoliosis patient, and in particular, in the case of adolescents, growth continues, so that there is a problem in that spinal correction cannot be effectively performed in the process.

Furthermore, there is a problem in that it is easy to give up the use of the assistive device because a patient who uses the inconvenient assistive device cannot be sufficiently motivated to use the assistive device.

Patent registration No. 10-1070973'Spine assist device' has been disclosed as a prior art in the above technical field.

The prior art relates to a spinal brace worn by a patient for spinal correction and recovery for spinal diseases such as curvature of the spine, and more particularly, in the case of a back plate composed of a conventional spinal brace, its shape is fixed and time elapses. In order to solve the problem of not effectively responding to the state of the spine of a patient according to the hammock, the length and angle can be adjusted, and the inner/outer shell is made of functional fiber and detached/attached to the back and pulled to allow tightening by simple operation. Optimized for the patient's back by dividing the back plate into upper and lower parts so that the length of the back plate can be adjusted and the angle can be adjusted. The back plate can be manipulated to have a length and angle.

However, the prior art has a structure in which the orthodontic patient is very difficult to adjust using a pull-line adjustment device, and thus, there is a problem in that it is essential to seek help from a third party when using a spinal brace.
