Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the overall structure of the anterior vertebral body fixation plate system is cumbersome and the number of components is increased due to the loosening and easy withdrawal of the screws of the existing anterior cervical spine fixation plate, the high notch and the use of locking plates to prevent the screws from loosening. A New Type of Anterior Cervical Vertebral Fixation Plate

Abstract

The invention relates to a novel anterior cervical spine fixing plate. The novel anterior cervical spine fixing plate comprises a bone setting plate and screws, wherein a plurality of universal locking holes and bone grafting windows are formed in the bone setting plate; arc-shaped decompressing grooves are formed in the bottom of the bone setting plate; each universal locking hole is a threaded hole formed by multi-piece splicing; each screw can be transplanted and locked deviating from an axis center within the range of 0-15 degrees; and a first thread structure, a second thread structure and a tapping auxiliary structure are arranged on each screw. The novel anterior cervical spine fixing plate disclosed by the invention has the advantages that universal transplanting and locking of thescrews can be performed; the structure is simple, additional screw withdrawing preventing device and screw withdrawing preventing operations are not needed, so that surgery time is saved, and the surgery efficiency is improved; and the incisure is low, so that postoperative complications are reduced, and the surgery prognosis life quality of a patient is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel anterior cervical spine fixation plate. Background technique [0002] At present, domestic and foreign surgical treatment of cervical spondylolisthesis, cervical intervertebral disc degenerative lesions, tumors, trauma, etc. all need to use an anterior cervical plate for internal fixation recovery. Although the application of anterior cervical plate is very popular, the complications related to it cannot be ignored. Screw loosening may occur in the anterior cervical plate. The loosening of the screw not only has potential danger to the surrounding important soft tissues, but also makes internal fixation easier. failure, thereby affecting the healing of the bone graft. In addition, since the spine of different patients has different anatomical structures, when using titanium plates for fixation, it is necessary to be able to adjust a certain angle during the operation to ...
