Description
Technical field
The present invention relates to bone surgery technical field of medical instruments, say it is that a kind of structure is simple in detail, fixed effect is good, without the need to the anterior cervical vertebrae internal fixation steel plate that second operation is fixing.
Background technology
We know, anterior cervical vertebrae internal fixation is the conventional means of the disease such as treatment cervical disc degenerative disorders, cervical spondylolisthesis, spinal canal stenosis, Cervical vertebral tumor, the failure of cervical vertebra joint fusion, cervical vertebra pseudoarticulation formation, cervical spine malformation.Using anterior plate fixation to do anterior cervical vertebrae internal fixtion use, is a kind of operation of maturation, and its main purpose is that it is stable, fixing to maintain between cervical vertebral body, rebuilds cervical stability, realizes intervertebral fusion.Existing anterior cervical vertebrae internal fixation steel plate comprises steel plate body and cone screw, steel plate body medial surface and cervical curvature match, the upper and lower both sides of steel plate body are respectively equipped with vertebral body screw hole and a pair lower cone screw hole on a pair, be respectively equipped with vertebral body screw in upper vertebral body screw hole and lower cone screw hole, a pair be respectively equipped with the stay of locking vertebral body screw between vertebral body screw hole and between a pair hypocentrum screw hole; During operation, in vertebral body screw hole two vertebral body screws are used the upside cone of adjacent to steel plate body and operative site two cones to be fixedly connected with, use two vertebral body screws in hypocentrum screw hole to be fixedly connected with downside cone, use stay by vertebral body screw lock.Existing this anterior cervical vertebrae internal fixation steel plate, when vertebral body instability, tumor operation or patient's osteoporosis, anterior plate fixation is fixed can not provide enough stability, the way of escape is needed again to perform the operation fixing, not only patient is caused to secondary injury, increases medical expense, and the state of an illness is recovered slowly.Cervical vertebral body is generally spongy bone, and fixed effect is generally poor, and stability and resisting pull out forces all can not meet the operation needs of vertebral body shakiness.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of structure simple, fixed effect is good, without the need to the anterior cervical vertebrae internal fixation steel plate that second operation is fixing.
The present invention solves the technical scheme that above-mentioned the deficiencies in the prior art adopt:
A kind of anterior cervical vertebrae internal fixation steel plate, comprise steel plate body and cone screw, the upper and lower both sides of steel plate body are respectively equipped with vertebral body screw hole and a pair lower cone screw hole on a pair, vertebral body screw is respectively equipped with in upper vertebral body screw hole and lower cone screw hole, it is characterized in that the steel plate body on a pair on the upside of vertebral body screw hole is provided with pedicle of vertebral arch screw nail on Long Circle, steel plate body on the upside of a pair lower cone screw hole is provided with pedicle of vertebral arch screw nail under Long Circle, is respectively equipped with pedicle screw in upper pedicle of vertebral arch screw nail and lower pedicle of vertebral arch screw nail.
Upper pedicle of vertebral arch screw nail described in the present invention and lower pedicle of vertebral arch screw nail are the Long Circle slotted eye matched with pedicle screw.
The medial surface front portion of the Long Circle slotted eye described in the present invention is in the inclined-plane matched with the head of a nail of pedicle screw.When the head of a nail downside of pedicle screw and the medial surface of Long Circle slotted eye are fitted, the head of a nail embeds in Long Circle slotted eye.
Described in the present invention a pair is respectively equipped with the stay of locking vertebral body screw between vertebral body screw hole and between a pair hypocentrum screw hole.
Anterior cervical vertebrae internal fixation steel plate provided by the invention in use, the upside cone of adjacent to steel plate body and operative site two cones is fixedly connected with by two vertebral body screws in upper vertebral body screw hole, two vertebral body screws in hypocentrum screw hole are fixedly connected with downside cone, use the root pedicle screw in pedicle of vertebral arch screw nail to be fixedly connected with the left or right pedicle of vertebral arch of upside cone, use the right side of the root pedicle screw in lower pedicle of vertebral arch screw nail and downside cone or left pedicle of vertebral arch to be fixedly connected with.
The pedicle of vertebral arch of anterior cervical vertebrae internal fixation steel plate of the present invention and cone and cone is connected and fixed, fixed effect is good, for vertebral body instability, tumor operation or the osteoporotic patient of patient, enough stability can be provided, fix without the need to second operation, reduce slight illness and the medical expense of patient, rehabilitation speed is fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of light plate body of the present invention.
Detailed description of the invention
Anterior cervical vertebrae internal fixation steel plate as shown in Figure 1 and Figure 2, comprise steel plate body 10 and cone screw 14, the upper and lower both sides of steel plate body 10 are respectively equipped with vertebral body screw hole and a pair lower cone screw hole 11 on a pair, a pair are respectively equipped with the stay 12 of locking vertebral body screw between vertebral body screw hole and between a pair hypocentrum screw hole.Vertebral body screw 14 is respectively equipped with in upper vertebral body screw hole and lower cone screw hole 11, feature of the present invention is that the steel plate body 10 on a pair on the upside of vertebral body screw hole is provided with pedicle of vertebral arch screw nail 13 on Long Circle, steel plate body 10 on the upside of a pair lower cone screw hole 11 is provided with pedicle of vertebral arch screw nail 8 under Long Circle, is respectively equipped with pedicle screw 15 in upper pedicle of vertebral arch screw nail 13 and lower pedicle of vertebral arch screw nail 8.
On Long Circle described in the present invention under pedicle screw slotted eye and Long Circle the medial surface front portion of pedicle screw slotted eye in the inclined-plane matched with the head of a nail of pedicle screw.Cone screw hole, upper pedicle of vertebral arch screw nail and lower pedicle of vertebral arch screw nail are countersunk screw hole.When the medial surface of the head of a nail downside of cone screw and pedicle screw and cone screw hole and Long Circle pedicle screw slotted eye is fitted, the head of a nail embeds in Long Circle slotted eye.
Anterior cervical vertebrae internal fixation with steel plate in use, with the vertebral body screw of two in vertebral body screw hole, the upside cone of adjacent to steel plate body and operative site two cones is fixedly connected with, be fixedly connected with downside cone with the vertebral body screw of two in hypocentrum screw hole, use the root pedicle screw in pedicle of vertebral arch screw nail to be fixedly connected with the left or right pedicle of vertebral arch of upside cone, use the right side of the root pedicle screw in lower pedicle of vertebral arch screw nail and downside cone or left pedicle of vertebral arch to be fixedly connected with.Fixed effect is good, for vertebral body instability, tumor operation or the osteoporotic patient of patient, can provide enough stability, fix without the need to second operation, and reduce slight illness and the medical expense of patient, rehabilitation speed is fast.
The pedicle of vertebral arch of anterior cervical vertebrae internal fixation steel plate of the present invention and cone and cone is connected and fixed, fixed effect is good, for vertebral body instability, tumor operation or the osteoporotic patient of patient, enough stability can be provided, fix without the need to second operation, reduce slight illness and the medical expense of patient, rehabilitation speed is fast.
