With functions of continuous, intermission, repeat step and other four traction modes, and automatic compensation of traction force.

 Cervical vertebra traction is integrated with lumbar vertebra traction. Can take lumbar or cervical treatment for two patients seperately or synchronously. In addition, this design proposal can save space and fund for investors.

Computer-controlled cervical vertebra traction. Patients are possesses of restoration devices for emergency control. Traction force and traction time are controlled by programs. With cervical vertebra traction excess force automatic protection function, automation can be fully realized.
