Description

Technical Field

[0001] The utility model belongs to the technical field of cervical vertebra fixation, and in particular relates to an apparatus for fixing the cervical vertebra when a patient with cervical vertebra fracture lies flat. Background Art

[0002] The cervical vertebrae refer to the cervical vertebrae, which are located below the head and above the thoracic vertebrae. They are located in the cervical spine and consist of 7 vertebrae, surrounding the cervical cord and its spinal meninges. They are connected by intervertebral discs and ligaments, forming a physiological curvature that convexes forward. The characteristics of the cervical vertebrae are that the vertebral bodies are small and oval, with transverse foramina on the transverse processes, through which the vertebral arteries and vertebral veins pass; the spinous processes are short and bifurcated; the joints of the upper and lower articular processes are approximately horizontal, allowing the neck to move flexibly. The upper and lower notches of adjacent vertebrae form intervertebral foramina, through which spinal nerves and blood vessels pass.

[0003] However, there are still some problems with the existing cervical fixation devices. Most of the existing cervical fixators are annular structures. When performing fixation work, the existing cervical fixation devices are mounted on the patient's neck, which can limit the neck. The fatness of the existing patients and the influence of their own skeletons cause the thickness of their necks to be different, and the existing cervical fixation devices have few sizes, which causes some overweight or underweight patients to be unable to choose the correct cervical fixation device, which causes secondary injury to their necks. At the same time, when the patient lies flat, part of the neck area will be suspended in the air, causing injury to the patient.

[0004] Therefore, how to fix the cervical vertebra of a patient with cervical vertebra fracture when lying flat is a problem to be solved at present. Utility Model Content
