technical field

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

Background technique

Cervical spondylosis is a common and frequently-occurring disease. With the development of society and changes in production and lifestyle, bad habits such as looking down at mobile phones, sitting for long periods of time watching computers, and blowing air conditioners are becoming more and more common in daily life. The incidence of cervical spondylosis is increasing year by year. , and getting younger. Relevant surveys show that the number of patients with cervical spondylosis in my country has reached 85 million, and there are about 1.5 million new patients with cervical spondylosis every year. Cervical spondylosis has gradually become one of the main diseases that threaten the health of our population. Non-surgical treatments for cervical spondylosis include traction, exercise therapy, massage, physical therapy, drugs, etc. Cervical traction therapy is one of the most commonly used and effective methods. Traction can relieve neck muscle spasm, correct intervertebral joint disorder, improve or restore the physiological curvature of the cervical spine, increase the intervertebral space and the upper and lower diameters of the intervertebral foramen, reduce the internal pressure of the intervertebral disc, and facilitate the repair and retraction of the intervertebral disc, thereby restoring or Rebuild the biomechanical balance of the cervical spine, relieve the stimulation and compression of the spinal cord, nerve roots, and vertebral arteries, and play a therapeutic role.

The Chinese utility model patent with the authorized announcement number CN201216666Y and the authorized announcement date of 2009.04.08 discloses a cervical spine radian traction device, including a seat body, a neck collar and a traction device are arranged on the seat body, and the height of the neck collar can be straightened according to the cervical spine To adjust the degree, the neck is raised by raising the neck collar, so that the neck is bent forward at a certain angle, and the traction device drives the neck collar to slide on the seat body, thereby pulling the cervical spine to achieve the correction of the cervical spine, but Since the traction direction is in the horizontal direction, which is inconsistent with the arrangement direction of the cervical vertebrae in the forward flexion state, traction on the cervical spine in this direction will not only fail to effectively restore the curvature of the cervical spine, but will also cause damage to the cervical spine. In addition, the traction device can only adjust the cervical spine to a forward-bending state, but cannot adjust the cervical spine to a backward-extending state, and the therapeutic effect of cervical traction is limited. At the same time, the neck is lifted up by raising the neck collar, so that the neck is bent forward at a certain angle, which is different from the natural state of cervical forward flexion, which will inevitably cause mutual movement between the neck collar and the neck. Although the displacement is small, the force is great. The patient's cervical spine is already damaged and relatively fragile. The pulling force other than parametric traction therapy will cause further damage to the patient's cervical spine tissue, aggravating the condition, and is extremely unfavorable to the treatment. .

The Chinese utility model patent with the application publication number of CN105662684A and the application publication date of 2016.6.15 discloses a traction rehabilitation system, including a mobile trolley lifting device, an arc traction auxiliary machine and an arc traction main machine, and the arc traction main machine is provided with a neck support Bracket and pillow support, the neck support bracket is equipped with a neck support belt, the lifting device of the mobile cart is raised, the height difference between the neck support belt and the bed surface makes the cervical spine bend forward, and the height difference between the neck support belt and the pillow support makes the cervical spine In the state of extension, the main traction machine and the traction auxiliary machine slide relative to each other, so as to perform traction on the cervical spine in the state of flexion or extension, but in the same way, the direction of traction is the same as that of the cervical vertebrae in the state of flexion or extension. The alignment direction of the bones is inconsistent, and the traction of the cervical spine in this direction will not only fail to effectively restore the curvature of the cervical spine, but will also cause damage to the cervical spine. At the same time, the neck is lifted up by raising the neck support, so that the neck is in a forward-bending state, or the cervical spine is in a state of extension through the height difference between the neck support and the pillow support, which is different from the natural state of cervical spine flexion or extension. , it will inevitably cause mutual movement between the cervical collar and the neck. Although the displacement is small, the force is large. The patient's cervical spine itself has been damaged and is relatively fragile. This kind of pulling force other than parametric traction therapy will affect the patient's cervical spine. The tissue causes further damage, which aggravates the condition and is extremely unfavorable to the treatment.
