This product has been designed according to the physiology dissection of the lumbar inter-vertebral disc in the human body and peripheral nervous tissue characteristics. It takes the hydraulic pressure as the motive source and applies the advanced technologies such as PLC rotation coder force sensor for three-dimensional directional and positioning control and all programs is controlled by computer. Under the quick traction the three-dimensional stereo space instaneously fulfills to the lumbar inter-vertebral disc in a multi-angle way certain combined actions and dynamics which can not be done by the doctors by using their techniques and skills. Under the slow retraction it can carry out the continuous; intermittent; reciprocating pulse retractions to the forward-bending waist or the straightening back in order to reach the curing purpose.

This product has functions of quick slow traction zero shifts forward-bending straightening back and rotation. The system has patient case record management and it also can type the patient case record for convenience clinical application and research work. Quick traction applies quick large force for traction and reset when slow traction it is of gentle traction automatic compensation gentle rotation yielding and reset. The supine prone traction can be chosen according to the patient's conditions. Patients can use both quick traction and slow traction in the same program and it greatly reduce the period of curing time.

This product has the obvious and outstanding curing to the protrusion of the lumbar inter-vertebral disc lumbar false sliding and shifting psoas muscle spasm thoracolumbar posterior articular dislocation thoracolumbar vertebral bend and compression fracture.
