Vertebral curvature tractor

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to vertebra curvature tractor.

Background

The adult spine is composed of 24 vertebrae, 1 sacrum, 1 coccyx, and bony connections therebetween. It is divided into 4 areas of cervical vertebra, thoracic vertebra, lumbar vertebra and sacrococcygeal bone, and is viewed from the side in a natural physiological state to form a curve, namely, lordosis of cervical vertebra, kyphosis of thoracic vertebra, lordosis of lumbar vertebra and kyphosis of sacrococcygeal bone, and 4 physiological curvatures are formed. The structure ensures that the spine is as elastic as a spring, and not only can bear load, but also can absorb shock.

The spondylopathy is that the sclerotin, intervertebral disc, ligament and muscle of the vertebra are affected, and then the spinal cord, spinal nerve, blood vessel and vegetative nerve are pressed and pulled to stimulate, thereby causing complex and various symptoms. The common diseases include cervical spondylosis (such as cervical spondylosis) and lumbar spondylosis (such as lumbar intervertebral disc protrusion).

In the massage pillow developed in the market for treating spondylopathy, a user needs to lie down or lean on the massage pillow to massage the vertebra in the process of using the massage pillow. When a user lies or leans on the massage pillow, the massage pillow needs to bear the huge acting force of the user when lying or leaning on, the massage pillow can deform greatly or even seriously, and the massage pillow can not realize the massage effect on the vertebra part as expected. Some massage pillows even can not be restored to the original shape due to excessive deformation, so that the massage pillows cannot be used continuously.
