Description
Technical field
This utility model relates to a kind of anterior locking cervical plate system, for cervical vertebra is carried out front fixed form treatment, belongs to technical field of medical instruments.
Background technology
Anterior cervical vertebrae simple bone graft merges owing to On graft area lacks reliable stabilizing measures, be susceptible to plant bone mass come off, bone grafting disunion or delayed union or pseudoarticulation formation, the pseudarthrosis incidence rate of anterior cervical decompression bone-graft fusion is high, and the pseudarthrosis incidence rate of the bone-graft fusion of multi-segmental is higher, become the difficult problem of puzzlement clinicist.
The appearance of anterior plate fixation, it is not only clinic to provide good fixing means, a stable support is provided for Cervical anterior fusion, shortens plant bone mass time of fusion, improve fusion rate, it is also possible to prevention Delayed onset cervical kyphosis and keep cervical vertebrae height.Use anterior plate fixation that cervical vertebra carries out the technology of front fixed form treatment, be widely used to the clinical treatments such as intervertebral disc disorder, wound, tumor, deformity, pseudarthrosis.Anterior plate fixation uses screw to be fixed, but after having performed the operation, screw easily produces and loosens and exit anterior plate fixation, cause operative failure even threat to life, bringing patient and have a strong impact on, existing screw lock mode is to be screwed into other screws again after screw is fixing or lock by modes such as snap rings, not only increases operating procedure, and lock unreliable, there is potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in construction, easy to operate, the most fixing, safe and reliable anterior locking cervical plate system.
The technical scheme in the invention for solving the above technical problem is: this fixed system includes anterior plate fixation and screw, anterior plate fixation is provided with the screw hole group of some row layout parallel to each other, each column screw hole group is made up of the screw hole of two next-door neighbours, screw is arranged in screw hole, it is characterized in that: also include compressing sheet, compress sheet overall in dual U-shaped, its both sides are provided with opening, it is provided with between the screw hole of said two next-door neighbour and compresses the groove that sheet matches, compressing sheet to be arranged in groove, the opening compressing sheet both sides can be with the head of clamping screw.
Screw described in the utility model is that self tapping is from the fixed angle screw bored or angle adjustable screw.
This utility model is when screw is fixed angle screw, and the angle between the longitudinal surface of anterior plate fixation, axis and the vertical line of screw place plane of screw is 7 ° or 7 °；In the horizontal face of anterior plate fixation, the angle between axis and the vertical line of screw place plane of screw is 8 ° or 8 °.
This utility model is when screw is angle adjustable screw, and the angle between the longitudinal surface of anterior plate fixation, axis and the vertical line of screw place plane of screw can be 8 ° to 6 °, 2 ° to 10 °, adjustment between 6 ° to 8 ° or 10 ° to 2 °；In the horizontal face of anterior plate fixation, the angle between axis and the vertical line of screw place plane of screw can adjust between 0 ° to 8 ° or 8 ° to 0 °.
The quantity of screw hole group described in the utility model is two groups, three groups, four groups or five groups.
