Description
Technical field
The utility model is related to a kind of posterior cervical hybridization operation single opening door system, is mainly used in spinal canal stenosis merging
Segmental defect is fixed, cervical ossified posterior longitudinal ligament merges in the operations such as Segmental defect is fixed.
Background technology
Clinically determine, cervical ossified posterior longitudinal ligament merges segmental not by spinal canal stenosis merging Segmental defect for multi-segmental
Stablize much, quadriplegia can be caused, thus disability rate is high, one after diagnosing, generally requires row operative treatment.For can be once
Operation releases two kinds of causes of disease, shortens the course for the treatment of, clinically has scholar to select posterior cervical open-door laminoplasty to expand shaping joint lateral mass
Screw internal fixation, it is intended that expand canalis spinalis and alleviate stable backbone while spinal compression, had confirmed by the follow-up of Immediate And Long Term
With preferable clinical efficacy.
In recent years, it is developed in the operation of posterior cervical single open-door as a kind of alternative of laminectomy, not only
It can be used for treating cervical spondylotic myelopathy, and cervical spinal instability and kyphosis deformity after laminectomy can be prevented.Operation method is
In enabling side, (crack between a door and its frame) vertebral plate grinds vertical shape bone groove with the lateral mass place of joint, in the corresponding portion in enabling side offside (hinge side)
V-arrangement fluting is made in position, retains the cancellous bone and internal layer cortex bone of 1.0mm thickness.After hinge side fluting is ready to, enabling area is cut off
The overlapped part of the ligamentum flavum and vertebral plate of upper and lower ends, separation cyst wall soft tissue and vein；Each section vertebra is opened successively
Plate.The operation of posterior cervical single open-door is advantageous in that than fracture or dislocation fusion can retain the activity of cervical vertebra, be particularly suitable for use in
The operation of long segment.
But single open-door operation back pullout (BPO) side vertebral plate is easily closed, and is caused and is closed the door again, the clinical condition of spinal canal stenosis is caused again
Shape.What, which prevents that vertebral plate from closing the door again, causes canalis spinalis ISR to turn into the focus of research.But in current Via Posterior Spinal Approach, there is no specially
It is applied to maintain cervical vertebra plate opening position, prevents the fixation material and device closed the door again.Clinically conventional steel wire or
The colligations such as silk thread are fixed, very unreliable after fixing, and influence Post operation effect, or postoperative complication occur.Therefore, in the prior art
Occur in that some dedicated for posterior cervical open the door operation titanium plates, the titanium plate by a TBE (threaded both ends) hole connection sheet and two
Individual special screw composition；Titanium alloy is used for material；Connection sheet can be with moulding in operation.Connection sheet one end is screwed
On the lateral mass do not taken away, the other end is screwed on the vertebral plate just resetted, and the left and right sides of vertebral plate, which is cracked, locates difference
It is fixed.However, the structure has the following disadvantages：1, titanium plate both ends to vertebral surface before fixing, it is necessary to carry out clear
Reason, especially needs that vertebra be surface-treated to make it coordinate the vertebral plate of titanium plate to fix at the spinous process of the hinge side of vertebra
Portion, so damages larger for patient's vertebra；2, monolithic titanium plate is only used for the positioning of single segmental vertebral plate, and adjacent two pieces of titanium plates
Between be not connected to, cause the titanium plate supporting construction stability that the operation uses still to lack, it is necessary to further reinforcing.
