Description
Technical field
A kind of posterior cervical plate is the utility model is related to, belongs to medical instruments field, suitable for cervical posterior approach.
Background technology
The patients with clinical manifestations of stenosis is with cervicodynia, numb limb is powerless, cotton is stepped in the tight beam sense of trunk and lower limb
Based on the typical cervical spondylotic myelopathy symptoms such as sample sensation, part merges nerve root or vertebral artery cervical vertebra disease symptoms, to cervical vertebra
Pipe stenosis early stage patient can take non-operative treatment, including the methods of braking, ion lead-in physical therapy and Chinese medicine, control and postponement
Sb.'s illness took a turn for the worse, but invalid to non-operative treatment, Relapse rate or progressively aggravates, and causes centrum art symptom then to perform the operation as early as possible
Treatment.Posterior cervical open-door laminoplasty Plastic operation is a kind of effective canalis spinalis posterior decompression for treating stenosis
Art, but traditional laminoplasty is commonly present that spinal canal decompression is insufficient and the complication such as occur closing the door again after opening the door, and influences
The late result of operation, in recent years many patients improve on this basis, achieve the effect of preferable.
The content of the invention
The purpose of this utility model is：The problem of existing for prior art, there is provided a kind of posterior cervical plate, preferably
The treatment of cervical spondylosis is realized, reduces the pain that operation is brought to patient.
To achieve these goals, the utility model provides a kind of posterior cervical plate, including upper plate body, connector, under
Plate body, supporting plate and foot stool；The upper plate body is connected with lower body by connector, and the upper plate body is in 135 ° with connector,
The lower body is in 135 ° with the connector；The supporting plate is in wide-angle V-arrangement, and the supporting plate upper end is divided in connector upper end four
One of place be connected with connector, supporting plate and connector are in 70 °；It is downward along connector in connector and lower body handing-over position
Extend foot stool in direction.
Preferably, upper plate body growth round shape, chute hole is set on upper plate body, chute hole upper end is annular prolate spheroid
Hole, lower end are annular slotted hole, and chute hole is consistent with upper plate body direction.
Preferably, the lower body is arranged to two arcuation faces being connected, and two sphere holes, sphere are set on lower body
Hole lower end is circular hole, and two sphere hole center line connecting directions are consistent with chute hole length direction.
The supporting plate and foot stool of posterior cervical plate of the present utility model can prevent cervical vertebra plate from moving, retraction, using the teaching of the invention it is possible to provide
Powerful support, good fixation is played, reduce bone grafting step, shorten operating time.The chute of posterior cervical plate upper plate body
Hole is designed, and is had and is slid axially, and adjusts way of escape vertebral plate open angle by chute.The thinner thickness of posterior cervical plate, has
1mm thickness, can be preferably bonded with bone, undercut mark with prevent stimulate surrounding tissue.
Posterior cervical plate of the present utility model, which has, to be avoided enabling vertebral plate from turning off, keeps canalis spinalis expansion to act on, and ensures hand
Smoothly insert and started in screw hole prefabricated on vertebral plate in art, reduce operation time and operation risk and adjusted by chute
The advantages that way of escape vertebral plate open angle.
Posterior cervical plate of the present utility model is simple to operate, practical during operation using novel design structure, reduces operation
Operating time, strengthen product safety coefficient, be suitable for Orthopedic Clinical popularization and application.

Fig. 2 is top view of the present utility model.
In figure,
1 upper plate body, 2 connectors, 3 lower bodies, 4 supporting plates, 5 foot stools, 6 chute holes, 7 annular long ball faces, 8 annulars are oval
Hole, 9 arcuation faces, 10 sphere holes, 11 circular holes.
Embodiment
In order to further illustrate the utility model, posterior cervical plate provided by the utility model is entered with reference to embodiment
Row is described in detail, but they can not be interpreted as to the restriction to scope of protection of the utility model.
Referring to figs. 1 to shown in Fig. 2, according to a kind of posterior cervical plate of preferred embodiment of the utility model, including upper plate
Body 1, connector 2, lower body 3, supporting plate 4 and foot stool 5；The upper plate body 1 is connected with lower body 3 by connector 2, it is described on
Plate body 1 is in 135 ° with connector 2, and the lower body 3 is in 135 ° with the connector 2；The supporting plate 4 is in wide-angle V-arrangement, described
The upper end of supporting plate 4 is connected at the upper end a quarter of connector 2 with connector 2, and supporting plate 4 is in 70 ° with connector 2；In connector 2
Join position with lower body 3, in downward direction extend foot stool 5 along connector 2.
The upper plate body 1 is grown up round shape, and chute hole 6 is set on upper plate body 1, and the upper end of chute hole 6 is annular long ball face 7,
Lower end is annular slotted hole 8, and chute hole 6 is consistent with the direction of upper plate body 1.
The lower body 3 is arranged to two arcuation faces being connected 9, and two sphere holes 10, sphere hole are set on lower body 3
10 lower ends are circular hole 11, and two center line connecting directions of sphere hole 10 are consistent with the length direction of chute hole 6.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
