The spine can be divided into cervical, thoracic, lumbar, sacral and caudal vertebrae from top to bottom. Wherein the cervical vertebra comprises 7 vertebrae, namely C1 vertebra to C7 vertebra from top to bottom; the thoracic vertebra comprises 12 vertebrae, namely T1 vertebra to T12 vertebra from top to bottom; the lumbar vertebra comprises 5 vertebrae, namely L1 vertebra to L5 vertebra from top to bottom; the sacrum has 5 vertebrae and is fused into one piece, called the sacrum; the coccyx has 4 vertebrae and is fused into one piece, called the coccyx. The vertebrae are gradually thicker from the top to the bottom, and the central vertebrae are provided with a hole, which are called vertebral canal, connected by the central holes of each vertebra and used for accommodating the spinal cord and protecting the spinal cord. The superior and inferior tracings of adjacent vertebrae enclose an intervertebral foramen, which is a portal through which segmental spinal nerves exit the spinal canal, and blood vessels and nerve branches enter the spinal canal. Each vertebra has a joint, known as an intervertebral joint, that connects adjacent vertebrae. Adjacent vertebral bodies are connected by fibrocartilaginous discs, known as intervertebral discs. The human vertebrae are connected together by intervertebral joints, intervertebral discs and ligament fascia surrounding them. At present, people sit in front of desks and on automobile seats for a longer time, the occurrence probability of spinal diseases in people is higher and higher, the spinal diseases are degenerative changes of sclerotin, intervertebral discs, ligaments and fascia of spines, the functions of the spinal diseases are finally reduced or lost, the health of human bodies is seriously harmed, and the adhesion of the degenerative fascia is a source for damaging the biomechanical level of spines.

The spinal traction can be divided into sitting traction, lying traction, inclined traction and inverted traction according to the traction body position, longitudinal traction pulling force can be applied to the spinal column through various methods during traction, the spinal column is subjected to traction, spastic muscle tissues are released, intervertebral joints are stretched, the pressure in intervertebral discs is reduced, intervertebral foramen and intervertebral joint structures are adjusted, the compression of adjacent tissues on nerve roots is relieved or reduced, and then relevant symptoms are relieved. In addition, there are some traction massage cushions in the prior art, which apply traction force to the spine of a patient by means of a structure on the traction massage cushion, for example, a traction massage mattress disclosed in the chinese patent application with application publication No. CN1069640A is made of elastic material, and the upper surface of the traction massage mattress is a wave form inclined from the middle part to the two end parts in the length direction of the mattress.

However, currently, when performing spinal traction, longitudinal traction force is applied to the entire spine singly, and due to different force bearing conditions of various parts of the spine, adverse effects such as excessive loosening of muscle tissues and ligaments, excessive widening of the vertebral body gap, reduction and straightening of the physiological curvature of the spine and the like are easily caused, and elderly patients need to be forbidden with caution.

The middle part of the left and right direction of the spinal tractor is provided with a groove which is communicated front and back, the groove is divided into a front section avoiding groove 11, a lumbar vertebra avoiding groove 21 and a sacrum supporting groove 31 which are respectively corresponding to the front section 10, the middle section 20 and the rear section 30, and the groove bottom surfaces of the front section avoiding groove 11, the lumbar vertebra avoiding groove 21 and the sacrum supporting groove 31 are all planes. The groove is used for avoiding the excessive support of the spine tractor on the spine 40 and can form a suspension support structure, thereby reducing the bearing force and traction resistance of the elastic support body on the corresponding part of the spine 40, enabling the spine 40 to be more easily pulled away, providing a reset moving space for the spine 40, enabling the vertebra to be more easily reset, protecting the spine 40 and avoiding the pain caused by the greater extrusion force on the spine 40. In this embodiment, the cross-section of the channel is generally trapezoidal and is flared to facilitate accurate entry of the spine 40 into the channel and to enable centering of the spine 40.

As shown in fig. 1 and 4, the sacral support groove 31 of the posterior segment 30 has a front end communicating with the lumbar avoidance groove 21 and a rear end extending rearward. The lateral wall of the sacrum supporting groove 31 is an inclined wall surface to form a bilateral symmetry flaring form, the width of the groove opening is gradually reduced from one end close to the lumbar avoidance groove 21 to the other end, the sacrum supporting groove can adapt to the shape of the sacrum, the sacrum supporting and righting effects are achieved on the sacrum, and the traction force on the physiological curvature of the spine 40 is enhanced. As shown in fig. 4 and 5, the oblique inclined surfaces 33 are formed on the top surfaces of the portions of the rear section 30 located on the left and right sides of the sacrum support groove 31 to support the transition portion between the buttocks and the waist of the user, the oblique inclined surfaces 33 on the top of the rear section 30 are lower at the side close to the sacrum support groove 31 than at the side far from the sacrum support groove 31 to form a structure with the left and right sides folded upward, and the front side is higher than the rear side to form a three-dimensional support together with the groove bottom wall and the groove side wall of the sacrum support groove 31 at the transition portion between the buttocks and the waist, thereby generating a three-dimensional traction force system.

As shown in fig. 1 and 4, the side wall of the lumbar vertebrae avoiding groove 21 on the middle section 20 is an inclined side wall, and is divided into at least two slope sections 22 from bottom to top, and the slopes of the two slope sections 22 decrease from the groove bottom to the groove opening in sequence, so that the flaring structure is formed integrally. The rear side of the groove wall of the lumbar avoidance groove 21 is connected with the groove wall of the sacrum support groove 31 on the posterior segment 30, and the bottom of the front side of the groove wall is connected with the groove wall of the anterior avoidance groove 11 on the anterior segment 10.
