AI Technical Summary
The contact area between the existing fixing stent and the shoulder after the cervical spine surgery is small, which causes the operator to still be able to move the neck within the moving range when using the fixing stent, affecting the recovery effect of the cervical spine.
A postoperative fixation bracket for cervical spine including a bracket body, a front connecting frame, a bracket, a strap, a rear connecting frame, a headrest, an auxiliary assembly and a support assembly is designed. By setting up auxiliary components and support components, the contact area between the bracket and the shoulder is increased, and the position of the shoulder support is limited through limiting frames, connecting rods, restraint frames, shoulder pads, U-shaped blocks, powerful magnets, and clamping pins.
By increasing the contact area between the bracket and the shoulder and the support limit on the shoulder support position, the movement range of the operator's head when using the fixed bracket is effectively reduced, and the recovery effect after cervical spine surgery is improved.

Technical Field
[0001] The utility model relates to the technical field of cervical vertebra care, in particular to a cervical vertebra post-operative fixing bracket. Background Art
[0002] The cervical spine refers to the cervical vertebrae, which are located below the head and above the thoracic spine. Located in the cervical spine, there are 7 vertebrae in total, surrounding the cervical cord and its spinal meninges, connected by intervertebral discs and ligaments, forming a physiological curvature that convexes forward; the characteristics of the cervical spine are that the vertebral body is small and oval, with transverse foramina on the transverse processes, through which the vertebral artery and vertebral vein 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 the intervertebral foramen, through which spinal nerves and blood vessels pass; and after cervical spine surgery, the surgeon's neck needs to be restrained with the help of a fixed bracket to reduce the pressure on the surgeon's neck and improve the recovery effect of the surgeon's cervical spine.
