Cervical traction device that returns to the physiological radian of the cervical spine

Abstract

The invention relates to a cervical vertebra tractor for restoring cervical vertebra physiological curvature. The tractor comprises a traction cap (2), a traction plate (6), a lever back plate (10), an oblique pull rod (3), a lifting rod (14), a lifting handle (9) and a cervical vertebra traction module (1); the oblique pull rod (3) and the lever back plate (10) are in rotary connection; the traction cap (2) is hinged to the traction plate (6); the lifting handle (9) is connected with the lifting rod (14) and drives the lifting rod (14) to slide along a sliding track (15); the cervical vertebra traction module (1) is fixedly connected with the traction plate (6) and is provided with an arc convex bock matched with the shape of a neck; the arc convex block is provided with a cervical vertebra gauging device (19). According to the cervical vertebra tractor for restoring cervical vertebra physiological curvature, various existing cervical spondylosis symptoms of a patient are fundamentally eliminated, more importantly, the starting factors of the cervical spondylosis are eliminated from the source, and the vicious circulation process of occurring, developing and evolving of the cervical spondylosis is obstructed.

Description

technical field [0001] The invention relates to a medical device, more specifically, to a cervical vertebra retractor for returning to the physiological radian of the cervical vertebra. Background technique [0002] The imperfection of human evolution is particularly prominent in the cervical spine. Due to the upright walking of human beings, on the one hand, the weight of the head is completely borne by the cervical spine; on the other hand, compared with the thoracic and lumbar spine, the bony stability factor of the cervical spine (its intervertebral facet joints are close to the horizontal direction) and its surrounding muscles The support, protection, and stabilization provided by the ligaments (soft tissue stabilizing factors) are very weak. Therefore, it is prone to strain, and then degenerates, leading to cervical spondylosis. [0003] With the aging of the population in our country and the great changes in the way of life and work, the incidence of cervical spondy...

Problems solved by technology

[0015] (1), any drug treatment: can only play an auxiliary role (relieve soft tissue spasm, relieve fatigue symptoms)

[0016] (2) Correction of technique: There are obvious defects: first, the magnitude of force cannot be quantitatively controlled; second, the direction of force is not easy to control subjectively, and lateral force often makes mistakes, and even leads to serious consequences such as high paraplegia; third, it is only a one-time operation. Potential, safety and effectiveness are severely limited

[0017] (3) Wearing neck circumference: only passive, statically stable, and protective against further dislocation, but no active function to correct existing dislocation

[0018] (4) The existing "Dr. Tian's cervical spine arc" is only equivalent to the function of "pillow" and has only a static effect, so it can only prevent but not correct the existing abnormal physiological curvature, that is, it lacks therapeutic effect

[0020] Although it has the function of dynamic traction, its traction force only acts in the vertical direction, which does not meet the requirements of the physiological curvature of the cervical spine itself. Therefore, it is impossible to correct the abnormal physiological curvature of the cervical spine, which fails to achieve the purpose of treatment, and even damages the ligaments and small joints.
