Adjustable cervical vertebra anterior approach operation position posing device used in spine surgery

Abstract

The invention discloses an adjustable cervical vertebra anterior approach operation position posing device used in the spine surgery. The adjustable cervical vertebra anterior approach operation position posing device comprises a bed board, a cross rod and a lower board, wherein a motor is fixed to the lower surface of the bed board, an output shaft of the motor is connected with an bevel gear, circular rings are fixed to the lower surface of the bed board and are in a sliding sleeved connection with drive shafts, the surfaces of rotation shafts are provided with a spiral insections, the bevel gear is meshed with the spiral insections of the rotation shafts, a double-rod design is adopted between the bed board and the cross rod, the neck is not blocked, and X-ray perspective can be directly performed. The device drives the bevel gear to rotate through the output shaft of the motor, the bevel gear drives the rotation shafts to rotate so as to achieve left-right movement of the rotation shafts, accordingly the distance between the head and the neck is adjusted to adapt to the neck lengths of different patients, a rotary lead screw and a connecting rod rotatably inserted into a lower board round hole are fixed through a stud to drive the lower board to rotate, accordingly different surgical angles are obtained, the surgical efficiency is improved, an the surgical risk is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable body position placement device for anterior cervical surgery for spinal surgery. Background technique [0002] Anterior cervical surgery is a common surgical procedure in spine surgery. It is used to treat cervical disc herniation, cervical fracture and dislocation, and cervical tumors. Prevent the patient's head from shaking after anesthesia; raise the shoulders and slightly raise the back of the pillow, and adjust the curvature of the cervical spine through the height of the shoulder and pillow cushions. Ideally, at the beginning of the operation, the cervical spine should be in a proper extension position, the mandible should be raised, and the front of the cervical intervertebral disc should be opened to facilitate surgical operations such as intervertebral disc / vertebral body resection; intervertebral fusion cage implantation is usually required in the ...

AI Technical Summary

Problems solved by technology

Ideally, at the beginning of the operation, the cervical spine should be in a proper extension position, the mandible should be raised, and the front of the cervical intervertebral disc should be opened to facilitate surgical operations such as intervertebral disc / vertebral body resection; intervertebral fusion cage implantation is usually required in the second half of the operation , Internal fixation with steel plates and screws. At this time, the patient’s cervical spine needs to return to a neutral position, or even a proper flexion position, so as to block and fix the implanted intervertebral fusion device, and at the same time restore the normal physiological curvature of the cervical spine. During the operation, X-ray perspective can adjust the cervical spine. The curvature of the spine is inconvenient, which increases the difficulty of surgical operations, especially the accurate installation of artificial intervertebral discs and internal fixation plates. Therefore, we propose an adjustable anterior cervical surgery position placement device for spinal surgery
