How to use the cervical retractor
1. Rotate the left and right handles with both hands at the same time to lower the lift tube to the lowest point, and adjust the traction belt and the fixed belt at the same time to the appropriate length.
2. Grasp the lower part of the retractor with both hands, lift it around the top of the head, place the bracket on the back of the shoulder, place the fixed belt on the back of the head, and place the traction belt on the tip of the chin. Hold your neck.
3. Turn the handle to the inside of the body with the left and right hands at the same time, and the left and right lift pipes will rise at the same time. Generally, the handle is rotated about 2 circles, and the traction belt should be fully tightened and enter the traction state. If the handle cannot be turned into the traction state after 2 turns, it means that the traction belt is too long and needs to be shortened.
4. In the process of turning the handle to gradually increase the traction force, press the set shrapnel with the thumbs of the left and right hands. When the shrapnel bends, it means that the maximum traction force that the shrapnel can provide has been reached, and the rotation is stopped. Handle and maintain traction for 15-30 minutes.
5. Finally release the traction, turn the handle to the outside of the body with both hands at the same time, so that the lifting tube is lowered to the lowest point, and a treatment can be completed.
What should I pay attention to when using cervical traction device
1. Angle of traction
Vertical spine Force is most suitable for restoring the physiological curvature of the spine and adjusting the mechanical balance inside and outside the spine. The 30° to 90° angle traction can instantly retract the vertebral body, restore the normal physiological curvature of the spine, and adjust the internal and external mechanical balance of the spine. It is the most effective traction angle for spinal traction.
2. Traction time
When the traction time was 15 to 20 minutes, 90% of the vertebral curvature tended to be normal, and the continuous traction exceeded 15 to 20 minutes. For more than 20 minutes, the patient will feel dizziness and nausea, so traction time of 15 to 20 minutes is the best. When you first start using it, please give the cervical spine a period of adaptation in 5 minutes, 10 minutes, and then 15 minutes.
3. Traction action
The traction effect can only be achieved by using the correct method, and the wrong action may cause discomfort. When using the retractor, it is necessary to place the high end of the installed stretcher facing forward on a hard bed or a flat and clean floor, and place it on the neck position when lying down (a 3-5cm high pillow can be placed on the head) . Gently close the legs, bend the knees so that the thighs and calves are in an A shape, support the body with both elbows back, and slowly lie down, press the back tightly on the traction device, the highest part of the traction device is against the cervical vertebrae, gently back and forth Adjust the body and head position to find the most comfortable point.
4. The magnitude of the traction force
When traction in the supine position (lying on your back), the vertebral body can only reach more than 10% of the body weight. Retraction, if the force is too small, the vertebral body cannot be retracted, and if the force is too large, the muscles and ligaments will be easily strained; through clinical case observation, according to different body weights, after giving different weights of traction, X-ray research shows that when lying down traction: traction force is body weight 10% to 15% is better. For the elderly and infirm, osteoporosis, intervertebral disc degeneration, and spinal cord type, the traction force should be less than 6%, so as to avoid causing or aggravating spinal instability due to the large displacement of the spine.
