Description

Waist traction device

Technical Field

The utility model relates to the field of medical instruments, in particular to a waist traction device.

Background

Traction treatment is widely applied clinically, and the main indications of the traction treatment are as follows: 1. for dislocation, traction may be used as a means for reposition after dislocation has occurred, or as a means for braking and fixing the joint after joint reposition. Such treatment may be applicable to dislocation of extremities or dislocation of the facet joints of the spine. 2. The traction device is used for fracture, traction is used as a temporary fixing measure, and the traction device can play a role in stabilizing the fracture end after traction. 3. For spinal deformities, distraction can be used as a means of correction when scoliosis occurs. 4. For muscle spasms, traction is continuously used at these sites to stabilize the portion of the spine and relieve muscle spasms on both sides of the spine as cervical spondylosis or lumbar disc herniation occurs.

The lumbar vertebra traction is to utilize traction force and reverse traction force to act on lumbar vertebra, and achieve the purpose of treating lumbar disc herniation through traction in opposite directions. Lumbar traction can increase lumbar intervertebral space, mainly lumbar 3, 4, 5, sacral 1 space. According to the research, the lumbar vertebra clearance is widened by 1.5-2.5 mm after traction compared with the lumbar vertebra clearance before traction, the internal pressure can be made negative by the widening of the lumbar vertebra clearance, and the tension of the posterior longitudinal ligament is beneficial to the restoration of the protruding nucleus pulposus part or the change of the relation between the protruding nucleus pulposus part and nerve roots. The enlargement of the intervertebral space and the pulling-apart of the articular process joint restore the intervertebral foramen to the normal shape, thereby relieving the extrusion of the nerve root. The traction can also make lumbar vertebra have sufficient rest, reduce the stimulation of movement, be beneficial to the absorption and the resolution of tissue congestion and edema, and can also relieve muscle spasm and relieve intervertebral pressure.
