Abstract

The invention relates to a long-arm occipital bone plate reduction internal fixation system used in occipital-neck fusion surgery. The long-arm occipital bone plate reduction internal fixation system used in the occipital-neck fusion surgery comprises an occipital bone plate, a fixing column and a fixing nut, the fixing column is located in a sliding groove screw hole of the occipital bone plate and used for containing a connecting rod, and the fixing nut is used for being fastened to the fixing column so that the connecting rod can be fixed to the fixing column. According to the long-arm occipital bone plate reduction internal fixation system used in the occipital-neck fusion surgery, occipital bone screw placement, connecting rod placement and reduction operation in the surgery can be facilitated, the operation time is shortened, the firmness of fixation between occipital bone screws and the occipital bone is enhanced, and the overall performance of the occipital bone plate reduction internal fixation system is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a long-arm occipital plate reduction and internal fixation system in occipital-cervical fusion. Background technique [0002] Occipitocervical fusion is a spinal surgery technique performed to maintain the stability of the atlantoaxial spine and reduce or relieve cervical spinal cord compression when the occipital-cervical junction is unstable due to congenital or acquired factors, or when the occipital-cervical instability causes compression of the cervical spinal cord. . Indications for this type of surgery include atlanto-occipital joint dislocation, occipital condyle fracture, atlas fracture, axis fracture and dislocation trauma to the cranial-occipital junction, congenital deformities, rheumatoid arthritis, and craniocervical junction tumors. [0003] Chinese patent CN 111759438A discloses a posterior reduction and internal fixation system, which includes two parall...
