Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a locking occipital plate with adjustable width.
Background
The spine diseases related to spine fracture, tumor, infection and degenerative diseases appear in human beings for a long time, along with the continuous development and exploration of modern medicine, the treatment of the spine diseases which afflict the human beings has been improved well, and products and technologies for surgical treatment in the aspect are quite perfect and mature. For example, the occipital plate is mainly applied to the bone surgery of occipital-cervical fusion, and is mainly matched with implants such as occipital screws, titanium rods, cervical pedicle screws and the like for the operative fixation of traumatic cervical vertebra fracture.
The existing occipital neck fusion system mainly comprises an integrated occipital plate and a split occipital plate, the integrated occipital plate adopts a cervical plate and occipital plate integrated structure, the occipital plate and the cervical plate are connected into a whole through a middle bridging plate and a bridging screw, the occipital plate is used for fixing the occipital bone, and the cervical plate is used for fixing a cervical screw rod system. The split type occipital plate adopts the combination of the occipital plate and the connecting rods of the cervical vertebra fixing screw rod system, namely, the occipital plate is fixed on the occipital bone by using occipital screws, and the occipital plate is fixed with the structure of the two connecting rods of the cervical vertebra fixing screw rod system. The integral occipital bone plate has a larger structure and a more complex structure, and the operation process is relatively difficult. The split type occipital plate structure is relatively small, and the operation is more simple. But at present no matter integral type occipital plate is split type occipital plate still, when the connective bar of the nail stick system of cooperation cervical vertebra is fixed, it is great all to have the crooked radian of connective bar, the knee degree of difficulty is big, relapse the curved tired problem of connective bar meeting cause of knee, need be equipped with the occipital bone board of a plurality of specifications and operate, increase manufacturing cost and operating cost, and the fixed occipital bone of occipital bone board all adopts occipital bone screw perpendicular to occipital bone board screw in occipital bone to lock, postoperative occipital bone screw appears easily because stress concentration and not hard up problem.
Disclosure of Invention
The present invention is directed to a locking occipital plate having an adjustable width that solves one or more of the problems set forth in the prior art and provides at least one of the advantages or features.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a width adjustable locking occipital plate, includes arch bridge shape occipital plate, connecting seat, occipital bone screw, C shape ring and snap ring, the both sides wing of arch bridge shape occipital plate is opened and is equipped with the regulation hole, but connecting seat and regulation hole sliding connection, the snap ring card is in the outside of connecting seat, a plurality of fixed orifices has been seted up at the middle part of arch bridge shape occipital plate, occipital bone screw runs through the fixed orifices, C shape ring sets up and establishes the head at occipital bone screw in the fixed orifices and cover, C shape ring can be at the downthehole activity of fixed orifices.
The both sides wing through arched bridge shape occipital plate is opened and is equipped with the regulation hole, connecting seat and regulation hole sliding connection, the snap ring card is in the outside of connecting seat, the connecting seat can be according to the width needs of connective bar in the operation remove on the regulation hole of arched bridge shape occipital plate's two flanks, avoid the connecting seat to drop through the snap ring cooperation simultaneously, thereby carry out the distance adjustment, can solve the problem that the connective bar need bend adjustment radian repeatedly in-process of performing the operation and cause connective bar bending fatigue, need not to be equipped with the occipital plate of a plurality of specifications, therefore, the cost is reduced, make things convenient for operation doctor's operation, reduce the connecting seat at radial atress, make connecting seat and connective bar locking. A plurality of fixed orifices has been seted up through the middle part of arched bridge shape occipital plate, occipital screw runs through the fixed orifices, C shape ring setting is established in the fixed orifices and the cover is established at the head of occipital screw, C shape ring can be at the downthehole rotation of fixed orifices, thereby occipital screw can pass through C shape ring at the fixed orifices activity of arched bridge shape occipital plate and can angle of adjustment, the angle of control screw in occipital bone, it is the angle cross fixation to let occipital screw, make occipital screw obtain great power of controlling in the inside cortex bone of occipital bone, improve occipital plate's resistance to extraction performance, reduce the risk that the secondary operation appears in the postoperative, accelerate occipital neck fusion operation's recovered speed, so that reduce the adverse effect that the postoperative led to the fact the patient.
As a further improvement of the technical scheme, the top of the connecting seat is provided with an internal thread hole and a screw plug, the bottom of the internal thread hole is provided with a U-shaped groove, and two side faces of the top of the connecting seat are symmetrically provided with U-shaped notches.
