Description

X-ray cervical spine lateral photography auxiliary device

technical field

The invention belongs to the field of medical devices, and in particular relates to an X-ray lateral photography auxiliary device for cervical vertebrae.

Background technique

Cervical spine X-ray examination is the most widely used radiological examination method for patients with cervical spondylosis, among which the lateral cervical spine is one of the routine examination items. The speed and convenience of X-ray photography have become the preferred choice for cervical spine examination. Cervical spine X-ray examination requires the following projection positions:

(1) The subject stands in front of the photo frame, with the right side close to the photo frame; the shoulders are lowered as much as possible, the midsagittal plane of the body is parallel to the photo frame panel; the head is tilted back, and the neck is placed on the midline of the irradiation field;

(2) The upper edge of the irradiation field exceeds the external ear hole by 2cm, and the lower edge of the flat manubrium notch contains the soft tissue of the neck before and after;

Center line: The center line is vertically injected into the cassette through the mandibular angle 2cm downward (the midpoint of the line connecting the plane of the thyroid cartilage and the anterior and posterior borders of the neck).

In the requirements of the above-mentioned projection position, it is difficult to grasp the scale of the subject's head back, and it is difficult to overlap the mandibular images on both sides at one time and form a level with the lower edge of the occipital bone. As a result, it is easy to block part of the cervical spine image in the imaging, which is easy to cause missed diagnosis or misdiagnosis. At the same time, in order to protect the subject from being damaged by X-rays, the subject should wear a lead cap on the head. The clinically commonly used lead cap structure includes the cap top and the cap circumference forming a whole. The shape is similar to the small round hat of the Hui people. Lead sheeting is laid on the top of the hat and in the girth of the hat. In cervical spine photography, the subject wears a lead cap. In order to meet the requirements for the projection position of cervical spine X-ray examination, the lead cap is easy to fall off when the head is tilted back, which affects the radiation protection effect. Patent Publication No. 208435659U discloses a cervical vertebra support device and a cervical vertebra dynamic lateral X-ray photography system, comprising a base and a support part capable of supporting the neck of a human body, and the base comprises a fixed part and a slide set on the fixed part The sliding part has a vertical sliding stroke on the fixed part, the base is provided with a restricting mechanism capable of restricting the sliding of the sliding part, and the supporting part is detachably and fixedly connected to the top of the sliding part. The cervical vertebra of the human body is supported by the support part, and the height of the support part is adjusted through the base, which can effectively enable the patient to keep the cervical vertebra stationary and form a hyperextension and hyperflexion position during the cervical dynamic lateral X-ray process. high image quality, providing important imaging data for later diagnosis and treatment. Patent Publication No. 205181372U discloses a special support for cervical spine open position X-ray photography, which is composed of an upper plate, a bottom plate, a front end plate, a rear end plate, a left plate and a right plate. Its main structure is composed of wooden boards in a "cuboids" shape. Among them, the upper plate and the bottom plate are rectangular structures, the bottom sides of the front and rear end plates are respectively arranged vertically with the short sides of the bottom plate, the front and rear side plates are rectangular structures located between the front end plate and the rear end plate, and the front and rear side plates are in a rectangular structure. The upper side of the front and rear side panels are fixedly connected to the upper end plate, the lower sides of the front and rear side panels are respectively fixedly connected to the two long sides of the bottom plate, and the side edges of the front and rear side panels are sequentially connected to the waist edges of the left and right end panels. Using the device to fix the upper and lower jaws of the patient can reduce the physical burden of the patient and make the examination more humanized. Reduce the number of patients' re-irradiation, so that the patient's X-ray ionizing radiation dose is minimized, thereby reducing the radiation carcinogenic rate. The device is made of wooden boards, has a simple structure, is convenient to use, and has a low manufacturing cost, and can be used to support the human body during the cervical opening position photography process. Although the prior art can solve some problems existing in the projection position required for cervical spine X-ray examination, it is difficult to popularize and use due to its complex structure and large volume.
