Description
Technical field
The present invention relates to medicine equipment, particularly a kind of vertebral plate raises device.
Background technology
Anterior cervical operation clinically becomes due to updating and promoting in treatment low portion of neck and short segment cervical spondylotic myelopathy
Good result is achieved, but solves Multilevel cervical spondylotic myelopathy and becomes still abnormal difficult.Therefore neck posterior approach then turns into treatment
The conventional modus operandi of Multilevel cervical spondylotic myelopathy.Posterior approach is by expanding canalis spinalis, by the presence of physiologic radian, ridge
Marrow moves after under " bowstring principle " acts on, and alleviates front and causes compressing of the pressure thing to spinal cord.
The operating procedure of neck posterior approach is at this stage：Patient takes prostrate, Qu Jing, upper body to raise position.Local infiltration anesthesia
Or general anesthesia, using straight cut is hit exactly after neck, cut subperiosteum after ligamentaum nuchae and peel off and appear spinous process, bilateral lamina and articular process
Inside portion, according to the positioning of spinous process form, appear lesion segment each vertebra section up and down.Punched in vertebral plate spinous process linking part, two
Lateral margin in the articular process of side vertebral plate, side elect hinge side as, grind off or bite away vertebral plate outer cortex bone and part cancellous bone, make V
Shape bone groove, its bottom is not up to vertebral plate internal layer cortex but cutting off, and opposite side is enabling side, row strip Laminectomy, and bilateral all should be
Operated on the inside of articular process on vertebral plate.Ligamentum flavum between the upper and lower vertebral plate of enabling section and under the vertebral plate of enabling section is cut off, appears vertebra
Pipe.Each vertebral plate in section that will open the door is suspended on the capsular ligament of right side with " 10 " number silk thread.Being pushed open by lateral hinge side of opening the door makes V shapes
Mouth is gradually drawn close, and is raised and is not easy wide, the otherwise possibility of easy increase offside complete fracture, or even cause tight to canalis spinalis internal shift etc.
Weight consequence.Appear dura mater, dural surface gelatin foam or take correspondingly sized fatty piece covering.Wound puts negative-pressure drainage tube.
When neck posterior approach carries out pushing enabling side open and raises the step for vertebral plate is depressurized, there is presently no special
Instrument, vertebral plate is raised push open enabling side usually using the rongeur of sharp mouth, in this course may be due to stinging bone
The fixed shakiness of pincers causes serious consequence, such as, when pushing enabling side open and raising vertebral plate, because rongeur fixes unstable, enabling side
Vertebral plate is raised when raising, is easy to resilience, and is beaten on the spinal cord of intraspinal tube, the major accident for causing patient to paralyse, therefore,
So far, there has been no easy to use, easily operation can be used in neck posterior approach and push open enabling side raising operation in vertebral plate
Instrument.
The content of the invention
For the above situation, to overcome prior art defect, the purpose of the present invention is just to provide a kind of vertebral plate and raises device, can
Effectively solve neck posterior approach and push open enabling side to raise in vertebral plate operation, rongeur in-convenience in use, hardly possible operation, effect
Difference, vertebral plate is when raising, easy resilience, the problem of causing peril to occur.
The technical scheme that the present invention solves is that coupler body has free end and connection end, and the free end length of coupler body is less than connection
The length at end, the top of coupler body is plane, the connection end of coupler body and the V-shaped connection of handle, and V-arrangement opening and coupler body opening are in phase
The free end of opposite direction, handle and coupler body is respectively placed in the both sides of the connection end of coupler body.
The present invention is simple in construction, easy to use, easy to operate, substantially increases operating efficiency, efficiently solves vertebral plate and lifting
When opening the problem of resilience, the generation of malpractice is avoided, improves the security of operation.

Fig. 2 is the schematic enlarged-scale view of the present invention.
Fig. 3 is the use state diagram of the present invention.
Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
Provided by Fig. 1-Fig. 3, structure of the invention is that coupler body has free end 1 and connection end 2, the free end length of coupler body
Less than the length of connection end, the top 3 of coupler body is plane, the 4 V-shaped connection of connection end and handle of coupler body, V-arrangement opening and hook
Body opening is in opposite direction, and the free end of handle and coupler body is respectively placed in the both sides of the connection end of coupler body.
Described coupler body be thick 2-4mm, wide 0.8-2cm steel plate bending into hook formation.
Spiny tooth 5 is evenly equipped with described coupler body inwall, prevents from slipping.
The connection end 2 of described coupler body and handle link together through arc-shaped transition section 7.
There is cone 6 on the extrados of described arc-shaped transition section 7.
Described arc-shaped transition section 7 is the curved plate body of bending.
The length of free end 1 of described coupler body is 2-6mm.
The length of connection end 2 of described coupler body is 12-20mm.
The length of top 3 of described coupler body is 3-6mm.
The length of described handle 4 is 10-15cm.
The connection end 2 of described coupler body and the angle of handle are 30-90 °.
It is convenient to hold fluted 8 on described handle 4, prevent from slipping.
In use, the present invention is inserted from the enabling side of vertebral plate 10, the free end of coupler body is close to the vertebra close to canalis spinalis 11
On plate madial wall, cone is pressed against on the vertebral plate lateral wall in the shifting type portion 9 close to vertebral plate and spinous process, to vertebral plate and the shifting type of spinous process
Pull handle in direction in portion, you can raising for enabling side vertebral plate easily is realized, it is time saving, it is laborsaving, make enabling side vertebral plate to hinge side vertebra
Plate is pushed open, V-shaped part is gradually drawn close, and the width raised can be according to dynamics free hold, and rapidly, fast, enabling side vertebral plate is being raised
When, controlled by coupler body, no resilience, no slippage, devoid of risk is securely and reliably, easy to use, substantially increases operating efficiency, effectively
Solve potential safety hazard, avoid the generation of malpractice, so as to reach quickening decompression rate, improve the mesh of operation safety
, in summary, the present invention has huge economic and social benefit.
