Description

Lumbar vertebra traction device with combined seat
Technical Field
The invention relates to the field of lumbar vertebra traction, in particular to a lumbar vertebra traction device with a combined seat.
Background
The lumbar traction is to utilize the traction force and the counter traction force to act on the lumbar, and achieve the purpose of treating the lumbar disc herniation by traction in opposite directions. Lumbar traction can increase the lumbar clearance, mainly the lumbar 3, 4, 5 and sacral 1 clearances. According to the research, the lumbar intervertebral space is widened by 1.5-2.5 mm after traction compared with the lumbar intervertebral space before traction, the inner part of the lumbar intervertebral space becomes negative pressure due to the widening of the intervertebral space, and the tension of the longitudinal ligament is favorable for the protruded nucleus pulposus part to reduce or change the relation between the protruded nucleus pulposus part and the nerve root. The intervertebral space is enlarged, and the zygapophyseal joint is pulled open, so that the intervertebral foramen can restore to the normal shape, and the extrusion to nerve roots is relieved. Traction can also make lumbar vertebra fully rest, reduce the stimulation of movement, be beneficial to the absorption and the elimination of tissue congestion and edema, and also can relieve muscle spasm and relieve intervertebral pressure.
