Problems solved by technology

[0003] However, there are deficiencies in the above two treatment options. Among them, the atlantoaxial release and reduction through the oropharyngeal approach and the posterior internal fixation and fusion need to cut two incisions on the front and rear sides of the atlantoaxial spine during the operation. The patient needs general anesthesia. After the release of the atlantoaxial spine during the operation under general anesthesia, changing the position when the atlantoaxial spine is extremely unstable may increase the possibility of cervical spinal cord injury causing high paraplegia or even death; Axial fusion and internal fixation, due to the narrow surgical field in the oral cavity, and currently there is no suitable atlantoaxial fusion device and tools available clinically, the operation is difficult and complicated

Abstract

The invention discloses a transoral anterior atlantoaxial lateral mass embolia fusion cage system and a using method thereof. The system comprises a fusion fixing device, a holding restorer and lifting-pulling restoring pincers; a first connecting part is arranged on the fusion fixing device, a second connecting part is arranged on the holding restorer, the fusion fixing device is connected with the holding restorer through the first connecting part and the second connecting part, the lifting-pulling restoring pincers at least comprise a first conduction part and a second conduction part, andthe holding restorer is located between the first conduction part and the second conduction part. The system is used for an atlantoaxial dislocation and basilar invagination operation; meanwhile, whenthe system is in use, the atlantoaxial anterior release restoring and fusion interior fixation operation can be ideally completed simply through one operation incision.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anterior peroral atlantoaxial mass joint reduction fusion device system and a method for using the same. Background technique [0002] Atlantoaxial dislocation and skull basilar depression and other upper cervical diseases cause abnormal atlantoaxial alignment. Atlantoaxial dislocation or instability can cause high cervical spinal cord compression leading to high paraplegia and even death. In view of this situation, the existing treatment options are: one is anterior atlantoaxial release and reduction via oropharynx and posterior internal fixation and fusion; the other is atlantoaxial fusion and internal fixation via oropharyngeal release and reduction. In this treatment plan, after releasing the lateral mass joints on both sides of the atlantoaxial vertebrae, the effect of decompression on the ventral side of the cervical spinal cord is achieved by pulling the axial vertebrae f...
