Electric Cervical Traction Device (also known as traction device, neck traction device, electric traction device or cervical traction device) is a physical adjuvant therapy device for the lower jaw or cervical spine. Powered by a built-in lithium battery, it uses a high-speed motor that, in conjunction with reduction gearbox gears, reduces speed and increases traction torque. It controls the up-and-down movement of the traction arm via knobs on the main unit or buttons on the controller to apply traction. Patients can set the required traction force and treatment duration via the controller.

Its working principle adopts a traction force feedback control mode: the motor is controlled by the above-mentioned knobs or buttons, and its clockwise or counterclockwise rotation drives the traction assembly to move up and down, generating traction force.
