The extension and retraction of the first supporting rod and the equal-length extension and retraction of the second supporting rod are matched with the extension and retraction of the third supporting rod, so that the shoulder bearing cushion mechanism and the head bearing cushion fixing mechanism can be jointly driven to be combined to ascend and descend. The first telescopic rod and the second telescopic rod stretch out and draw back in a combined mode, the shoulder pressing plate slides, the shoulders of a patient are drawn, the cervical vertebra of the patient is drawn, the device can adapt to patients with different neck lengths, and the cervical vertebra is drawn to the proper length. The head cushion fixing machine stably fixes the head through the combined action of the head pressing plate and the restraint strap, enables the head of a patient to be lower than the shoulders, and enables the neck to stretch backwards through the height difference. The head pressing plate is pressed downwards from the forehead of the patient for fixation; therefore, the head of the patient is kept in a stable backward stretching position, so that the required neck curvature is kept.

Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an adjustable body positioning device for anterior cervical surgery. Background Art

[0002] Anterior cervical spine surgery mainly relieves the compression of the spinal cord or nerve roots through an incision in the front of the patient's neck, while restoring the normal physiological curvature and stability of the cervical spine. This surgical method has the characteristics of good exposure, less trauma, less bleeding, and fast recovery. It is especially suitable for patients with mild intervertebral degeneration, simple disc herniation or segmental instability of the cervical spine. The surgical steps usually include two parts: decompression and reconstruction of stability. First, the doctor will make a transverse incision on the front of the neck, peel off the skin and tissue, and expose the front of the cervical spine. Subsequently, the diseased intervertebral disc or hyperplastic bone is removed to relieve the compression of the spinal cord. If necessary, bone graft fusion and internal fixation will be performed to restore the stability of the cervical spine. In summary, anterior cervical spine surgery is an effective method for treating cervical spondylosis, but it must be performed under the guidance of a professional doctor, and attention should be paid to postoperative care and individualized treatment.

[0003] During anterior cervical spine surgery, the patient needs to be placed in a supine position with the head and neck appropriately extended backward, the shoulders raised, and the head fixed. Since most surgeons are right-handed, the patient's head and neck need to be tilted about 15 degrees to the right hand side to correct the visual field deviation of right-handed surgeons.

[0004] However, in the past, the preoperative positioning operation of the anterior cervical spine surgery usually involves appropriate modification of the operating table, suspending the patient's head, using an ordinary pillow to raise the patient's shoulders, and then manually fixing the head by medical staff. This positioning method usually has the following technical problems: 1. The modified operating table has a single function and only has the function of supporting the patient's head straight. It cannot flexibly adjust the height of the patient's head and stably fix the head at the same time; 2. It does not have the function of stably fixing the head while rotating the head to a certain angle to both sides; 3. It cannot pull the shoulders to reduce the obstruction of the lower cervical spine perspective; 4. The single fixation method for the head leads to unstable fixation, and long-term supine lying and the non-breathable ordinary pillow lead to occipital pressure sores.

[0005] Therefore, it is necessary to provide an adjustable anterior cervical surgery body positioning device to solve the above technical problems. Summary of the invention
