A cervical traction device with adjustable neck bracket angle

technical field

The utility model relates to the technical field of medical instruments, in particular to a cervical traction device with an adjustable neck bracket angle.

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 my country's 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.

In order to alleviate and treat cervical spondylosis, the utility model patent with application number CN201721043885.9 discloses a cervical traction device, including a base, a rotating platform, a rotating drive assembly, a traction platform, a traction drive assembly, a head and neck fixation assembly and a main control system , the rotary drive component drives the rotary platform to rotate relative to the base, the rotary platform is provided with a traction slide rail for the traction platform to slide, the traction drive component drives the traction platform to slide along the traction slide rail, the head and neck fixing component is arranged on the traction platform, the head and neck The fixed component includes a neck support component, a pillow support component and a forehead fixed component, and the main control system controls the rotation drive component and the traction drive component. According to the degree of cervical lesions of the patient, the rotating drive component drives the rotating platform to rotate to a suitable angle relative to the base to simulate the normal forward flexion or extension of the cervical spine in the natural state of the human body, so that the cervical spine is in a state of flexion or extension at this angle. The head and neck fixation component fixes the patient's head on the traction platform, and the traction drive component drives the traction mechanism to slide along the traction slide rail in the direction of the angle, so as to traction the cervical spine. Using the above traction method, the traction direction is the same as that in the forward bending state or In the state of extension, the alignment direction of the cervical vertebrae in the cervical spine is the same, and the traction of the cervical spine in this angle direction is more in line with the medical principle, and the therapeutic effect of cervical traction is better.

The neck collar of this device can only adjust the left and right width and narrow distance, but not the angle. It does not fit tightly for patients with different face shapes. Since the traction force is mainly provided by the neck collar, if the neck collar does not fit well, it will increase during traction. The pressure of the neck brace on the mandible, causing discomfort to the patient.

Utility model content

The purpose of the utility model is to solve the problem that the angle of the neck collar of the existing cervical vertebra traction device cannot be adjusted, which causes discomfort to the patient during traction, and provides a cervical vertebra traction device with an adjustable neck collar angle.

The technical solution adopted by the utility model is: a cervical traction device with adjustable neck bracket angle, including a base, a traction platform, a head fixing component, a neck fixing component and a main control system. Clamp the neck collar of the patient. The neck collar screw rod of the traction platform is provided with sliders. The left and right sliders are threaded with the neck collar screw rod, and the threads are in opposite directions. The slider is equipped with a cylindrical mounting column. A neck bracket fixed block is rotatably connected to the mounting column, and the neck bracket fixed block is connected with a neck bracket made of flexible material on the outside.

Further, the neck bracket fixing block includes a middle fixing column, and an outwardly protruding edge is arranged under the fixing column, and the convex edge matches with the bottom surface of the neck bracket, and a guiding column is also arranged on the convex edge.

Further, two guide columns are respectively arranged on both sides of the fixed column.

Further, a hole is opened on the outer cylindrical surface of the installation column, and an outwardly protruding flange is arranged in the hole, and the flange is connected with the side wall of the installation column through the connecting piece, and the corresponding flange is provided on the side wall of the fixed column. There is a horizontal arc-shaped hole, so that the flange is stuck in the arc-shaped hole and cannot move up and down but can only rotate horizontally.

Further, two symmetrical flanges are arranged on the mounting column, and two symmetrical arc-shaped holes are correspondingly arranged on the side wall of the fixing column.

Further, the upper end surface of the flange is a slope with a high inside and a low outside, which is convenient for the fixing column to be fitted on the installation column.

Further, the central angle of the arc-shaped hole is 60-120°.

Beneficial effects of the utility model: the utility model is simple in structure and reasonable in design, and the neck collar can’t be taken out because of the clamping of the fixed column by the flange. The rotation angle enables the neck collar to rotate within a limited angle range, so that the neck collar can fully fit the patient's neck and relieve the pressure on the mandible.
