Steel plate for anterior cervial internal fixation and guiding device

Abstract

The invention relates to a steel plate for anterior cervial internal fixation and a guiding device, and relates to the technical field of medical apparatus and instrument for orthopedic operation. The steel plate comprises a steel plate body and cone bolts. A pair of upper cone bolt holes and a pair of lower cone bolt holes are formed in the upper side and the lower side of the steel plate body respectively. The cone bolts and a long circular upper pedicle screw hole are arranged in the bolt holes, and pedicle screws are arranged in pedicle screw holes. The guiding device comprises a fixing rod, a guiding arm, a guiding rod and a fastening device. The steel plate for anterior cervial internal fixation and the guiding device have the advantages that the fixing effect is good, enough stability can be provided, secondary operative fixation is not needed, indisposition and medical cost are reduced, and the recovery speed is fast.

Description

technical field [0001] The invention relates to the technical field of medical instruments for orthopedic surgery, and in detail relates to a steel plate and a guide device for anterior cervical internal fixation with simple structure, good fixation effect, and no need for secondary surgical fixation. Background technique [0002] We know that anterior cervical internal fixation is a common method for the treatment of cervical degenerative disc disease, cervical spondylolisthesis, cervical spinal stenosis, cervical tumor, failure of cervical joint fusion, formation of cervical pseudarthrosis, and cervical deformity. The use of anterior cervical plate for internal fixation of the cervical spine is a mature operation. Its main purpose is to maintain the stability and fixation of the cervical vertebrae, rebuild the stability of the cervical spine, and achieve intervertebral fusion. The existing steel plate for anterior cervical internal fixation includes a steel plate body and ...

AI Technical Summary

Problems solved by technology

The existing steel plates for anterior cervical internal fixation cannot provide sufficient stability when the vertebral body is unstable, undergoing tumor surgery or patients with osteoporosis, and the posterior fixation is required. Patients cause secondary harm, increase medical costs, and recover slowly

Cervical vertebral body is generally cancellous bone, the fixation effect is generally poor, and the stability and pull-out resistance cannot meet the surgical needs of vertebral instability
