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

Abstract

The invention discloses a guiding device for an anterior cervical internal fixation and relates to the technical field of medicinal instrument and apparatuses for an orthopedic surgery. The guiding device comprises a positioning plate and a guider, wherein the positioning plate comprises a development board and a fixing plate; positioning holes are uniformly formed in the positioning plate; the guider comprises a fixing rod, a guiding arm, a guiding rod and a fastening device. According to the guiding device disclosed by the invention, a doctor is enabled to conveniently and accurately determine implantation points and implantation angles of pedicle screws, and the difficult problems of operation failure and injury to artery and nerve are easily caused when anterior cervical pedicle screws are fixed due to difference of angles and positions of pedicles of different patients are solved; by matching with a steel plate for use, the guiding device has beneficial effects that a fixing effect is excellent, and enough stability can be provided; secondary operation for fixing is not needed, so that pains of the patient and medical expenses are reduced; rehabilitation speed is high, and the like.

Description

technical field [0001] The invention relates to the technical field of medical instruments for orthopedic surgery, in detail, it is a guide device for anterior cervical internal fixation that has a simple structure, is easy to use, and can accurately determine the implantation point and implantation angle of a pedicle screw. 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...
