Abstract
The invention discloses a posterior cervical vertebra plate clamp. The overall structure of the posterior cervical vertebra plate clamp is in a bridge shape, the posterior cervical vertebra plate clamp is composed of a connecting plate mainly of a supporting structure, an inner clamping plate and an outer clamping plate, the inner clamping plate and the outer clamping plate are arranged on the two sides, and fixed tooth and fixed holes are arranged on the inner clamping plate and the outer clamping plate respectively. The posterior cervical vertebra plate clamp can be used for auxiliary treatment of cervical spondylotic myelopathy, congenital cervical spinal stenosis, multi-segmental cervical degeneration with spinal canal stenosis, ossification of posterior longitudinal ligaments, excessive cervical lordosis and other diseases. Compared with a traditional nail rod system and an unilateral door opening fixing system, surgical risks can be effectively reduced, the surgical process can be effectively simplified, the problem that vertebral plate expanding forming postoperation stability is poor can be solved successfully, the phenomenon that a door is closed after the two sides of the door is opened is avoided, and the spinal cord is protected against compression of the outside after the door is opened.
Description
Technical field
This invention relates to a kind of technical field of medical instruments, is specifically related to a kind of posterior cervical interlaminar clamp of posterior cervical laminoplasty enlargement of cervical canal.
Background technology
Cervical spondylosis is orthopaedics commonly encountered diseases, frequently-occurring disease.To cervical spondylotic myelopathy, Development cervical canal stenosis disease, long segment ossified posterior longitudinal ligament or ossification of ligamenta flava, cervical vertebra multi-segmental degenerative change, and cervical spondylosis anterior decompression is dissatisfied does not make remission person, clinically adopt posterior cervical laminoplasty enlargement of cervical canal more.Since Japan in 1970 carries out way of escape cervical vertebra plate forming art, single open-door cervical vertebra Plastic operation has been acknowledged as one of most effective method for the treatment of stenosis.But there is the shortcomings such as postoperative canalis spinalis restenosis and Sagittal alignment and limit its popularization in traditional single open-door operation.
Seek a kind of easy and simple to handle in recent years, fixing reliable and the improvement single open-door of satisfactory effect operation fixed form becomes new study hotspot, become and multiple cervical vertebra single open-door fixing head that to emerge with Certerpiece titanium plate be representative.All only split reveal in above-mentioned cervical vertebra single open-door fixing head to be fixed, do not fix door-hinge side vertebral plate and lateral mass simultaneously, an entirety cannot be formed, fail physiology posterior cervical vertebral canal reconstruction overall anatomical structure, therefore its anti-fatigue performance is poor, effectively cannot disperse the pressure from cervical vertebra dead astern, under certain physical stress load, En bloc laminoplasty back pullout (BPO) may occur and close again, cause operative failure.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of operation technique simple, the posterior cervical interlaminar clamp of stability reconstruction can be realized for canalis spinalis after posterior cervical laminoplasty.Above-mentioned posterior cervical interlaminar clamp adopts integrated design, overall structure be bridge type, the problem of Laminoplasty rear stability difference can be solved, prevent double door after the phenomenon of closing again occur, protection open the door after spinal cord do not oppress by extraneous.
To achieve these goals, technical scheme of the present invention is to provide a kind of posterior cervical interlaminar clamp.To be bridge type be made up of clamping plate inside and outside mainly playing the connecting plate of supporting construction and both sides above-mentioned interlaminar clamp overall structure, inside and outside clamping plate are equipped with fixed teeth and fixing hole, under normal circumstances fixed teeth namely to can be and postoperatively provide necessary stability, if staple can be pressed in fixing hole during stability deficiency excessive for inner splint institute open walk in art.The invention provides the technical scheme of various ways, implantable bone type interlaminar clamp can carry out sclerotin Hui Zhi, locking-typed interlaminar clamp can use lock screw to be fixed according to demand in art simultaneously.
Above-mentioned posterior cervical interlaminar clamp structure is simple, processing easily realizes, and implantation process is safer, easy, less to patient trauma, shortens operating time simultaneously, reduces operation risk.Can be used for the auxiliary treatment of the diseases such as cervical spondylotic myelopathy, congenital spinal canal stenosis, multi-segmental cervical spine degeneration companion spinal canal stenosis, ossified posterior longitudinal ligament, cervical lordosis be excessive.Compare traditional nail-stick system and one-sided enabling state fixed system can effectively reduce operation risk, simplify operation process, successfully can solve the problem of Laminoplasty rear stability difference, prevent double door after the phenomenon of closing the door again occur, protection open the door after spinal cord by extraneous compressing.

Detailed description of the invention:
By reference to the accompanying drawings the structure of posterior cervical interlaminar clamp of the present invention is illustrated.
As shown in drawings, posterior cervical interlaminar clamp overall structure of the present invention is that bridge type is equipped with fixed teeth (4) and fixing hole (5) primarily of connecting plate (1), external splint (2), the inside and outside clamping plate of inner splint (3) composition, fixed teeth (4) can play the anti-skidding effect of anti-back after Using prosthesis, and sclerotin grows into same entirety at healing phases by fixing hole (5) and can be and postoperatively provide lasting stability.Staple (6) can be pressed into improve the stability recovered postoperative early stage from the fixing hole (5) of external splint (2) both sides according to operation demand, the technical scheme that Fig. 4 also can be adopted in order to achieve the above object to provide, employing are provided with the interlaminar clamp of lock hole (8), by lock screw being adopted to be fixed in lock hole (8) art.Providing structure shown in Fig. 3 to accelerate this invention of postoperative recovery simultaneously, being provided with bone grafting nail (7) in connecting plate and can carrying out sclerotin Hui Zhi by bone screw.
Posterior cervical interlaminar clamp of the present invention is achieved in that
Shown in accompanying drawing, in art, use abrasive drilling to remove spinous process along vertebral plate center line to disease vertebral body, by vertebral plate opening, go out to grind off lateral cortex bone in both sides door-hinge and use special vertebral plate pincers to be launched laterally by both sides vertebral plate.Vertebral plate after can directly using the interlaminar clamp curb pins plate holder of suitable types to live to open the door for thin vertebral plate, with above-mentioned vertebral plate pincers by curb pins board clamping, for ensure fixing after stability can knock vertebral plate clamping with awl and get device and make the position of interlaminar clamp more deep.Gag can be used to form interlaminar clamp inner splint passage in vertebral plate section opening for thick vertebral plate, then interlaminar clamp inner splint be implanted passage, with the tight external splint of vertebral plate clamp as shown in Figure 6.
The above, it is only preferred embodiments of the present invention, not any pro forma restriction is done to the present invention, although the present invention with preferably instant disclosure as above, any those skilled in the art, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, all still belonging in the scope of technical solution of the present invention.
