Problems solved by technology

[0005] In addition, the existing lower cervical anterior screw fixation devices are mostly made of alloy materials, which cannot be degraded and absorbed by the human body, so a second operation is required to remove them after a period of time; this will not only cause considerable physical and mental damage to the patients , and will cause additional economic expenditure, so it is necessary to further improve the existing lower cervical anterior screw fixation device

Abstract

The invention discloses a lower cervical spine anterior pedicle screw matching fixing device which comprises a fixing plate and pedicle screws which are matched. At least two fixing holes matched with the pedicle screws are formed in the fixing plate. The cross section and the longitudinal section of the fixing plate are of an arc structure. The axis of each pedicle screw and the cross section of the fixing plate form a heeling angle of 15-30 degrees. The axis of each pedicle screw and the longitudinal section of the fixing plate form a trimming angle of 0-15 degrees. The pedicle screws are provided with fixing gaskets which are matched respectively. The fixing plate, the pedicle screws and the fixing gaskets are made of biodegradable materials. The implanting operation space of the pedicle screws is increased, and fixing of the fixing plate can be well achieved. When the pedicle screws are implanted completely, the heads of the pedicle screws are placed in the fixing holes. The lower cervical spine anterior pedicle screw matching fixing device is simple in structure and convenient to machine, the cross section and the longitudinal section of the fixing plate are of the arc structure, and accordingly fixing of the fixing plate and a spine body is firm.

Description

technical field [0001] The invention relates to the technical field of cervical spine fixation devices, in particular to a lower cervical spine anterior pedicle screw fixation device. Background technique [0002] There have been many reports on the use of anterior cervical restrictive or semi-restrictive plate fixation combined with vertebral monocortical screw fixation at home and abroad. However, for the technology of anterior pedicle screw in the lower cervical spine, it is just in its infancy abroad, with only sporadic clinical reports, and few systematic anatomical, imaging, and biomechanical research reports. Domestically, it is still in a blank stage. So far, there have been no basic research and clinical reports on the anterior lower cervical pedicle screw in China, let alone the design and application of the fixation and anti-off device for the anterior lower cervical pedicle screw. reports. [0003] The advantages of anterior pedicle screws in the lower cervical...
