[0002] In cervical spine surgery anterior approach operation, position setting is one of the key factors for the success of the operation. The position setting for cervical spine surgery anterior approach usually adopts a supine position, the patient's neck is slightly overextended, and small sandbags are placed on both sides of the head to prevent displacement. The cervical spine surgery anterior approach position is limited to ensure the safe and effective performance of the operation. The cervical spine surgery anterior approach position setting device includes an adjustable cervical spine surgery anterior approach position setting device, a combined gel position pad, an electric surgical position fixing frame system, etc.

[0003] As disclosed in CN105434057B, an adjustable cervical spine surgery anterior approach position setting device is disclosed, which includes a chest fixing plate, a connecting rod combination A, a connecting rod combination B, a connecting rod E and a head fixing device. The front end of the chest fixing plate is respectively provided with a tubular tunnel A and a tubular tunnel B. The connecting rod combination A includes a connecting rod A and a connecting rod B. The connecting rod combination B includes a connecting rod C and a connecting rod D. The crossbar A is provided with a connecting hole. The procedure of cervical spine patient position setting in spine surgery is reduced, the operation efficiency is improved, and the operation risk is reduced.

[0004] As disclosed in CN213217725U, a body position setting device for cervical spine surgery anterior approach is disclosed, which includes a bottom pad, a head fixing assembly, a pillow pad, a neck pad and a shoulder pushing assembly are sequentially fixed on the bottom pad. The shoulder pushing assembly includes a left shoulder pushing part and a right shoulder pushing part, and the left shoulder pushing part and the right shoulder pushing part are both arc-shaped protrusions that can semi-cover the human shoulder and prevent the human shoulder from moving upward. During the operation, the patient's cervical spine can be fully exposed, and the occurrence of skin pressure ulcers and injuries can be avoided.

[0005] As disclosed in the publication number CN221061141U, a adjustable cervical spine anterior approach operation body position placing device is disclosed, comprising: a base, a support assembly, a bed body, a head and neck assembly; the bed body is stably supported by the base and the support assembly, and the overall height and angle of the bed body relative to the ground are adjusted by adjusting the equal or unequal length extension of the inner member of the support assembly; the patient on the bed body is stably constrained by multiple restraint belts, the head is placed on the annular headrest and is stably constrained by the head restraint belt and the baffle; when the filling pillow is not placed under the back of the head or the filling pillow is deflated and concave, the patient's cervical spine is in the forward bending position together with the inflated neck pillow; when the filling pillow is placed under the back of the head or the filling pillow is inflated and raised, the patient's cervical spine can restore to the neutral position with the atrophied neck pillow; the operation body position placing device can provide stable body position placing and fixing for patients with different cervical spine lengths, and adjust the extension and neutral position of the cervical spine according to the operation needs; the normal physiological curvature of the cervical spine is crucial for maintaining the stability of the spinal cord and nerve roots, and if this curvature cannot be restored or maintained through body position adjustment during the operation, it may cause intractable neck pain after the operation, and even accelerate the degeneration of the adjacent segments; the existing part of the body position placing equipment has limited adjustment, and the medical staff needs to increase additional tools such as sandbags to assist in limiting the patient's body position during the adjustment process, which is very inconvenient to operate, and after the patient's body position is limited, it is not convenient to fix the limited position of the head, and if the patient moves after adjustment, it will affect the stability of the overall body position adjustment.
