One class " z " shape, vertebral plate fixing end 11 is provided with two in line through holes 111, and short bone nail 3 is coordinated with line through hole 111, and lateral mass is solid
Two horizontally-arranged through holes 131 are provided with fixed end 13, long nail 4 is coordinated with horizontally-arranged through hole 131.It is provided with section start on short bone nail 3
Self tapping cutting edge 31.Section start self tapping cutting edge 41 is provided with long nail 4.
In this utility model, fixed plate main body 1 adopts ultrathin design, specifically: vertebral plate fixing end 11, inclined-plane ribs
12 and lateral mass fixing end 13 there is same thickness, be 0.8mm~1.0mm, preferably 0.8mm;The width l of inclined-plane ribs 12 is little
Breadth Maximum in vertebral plate fixing end 11 and the Breadth Maximum less than lateral mass fixing end 13;The width of inclined-plane ribs 12 is
4.5mm~5mm, preferably 4.5mm;The Breadth Maximum of vertebral plate fixing end 11 is 6mm~10mm, preferably 6mm;Lateral mass fixing end
13 Breadth Maximum is 6mm~10mm, preferably 6mm.That is, inclined-plane ribs 12 vertebral plate fixing end 11 and lateral mass relatively
Fixing end 13 more narrows.
This utility model is based on above-mentioned design, and system has good elasticity so as to can preferably paste under screw pressurization
Close bone face, after implantation, forming force is actively applied by vertebral plate itself, system only serves stress effect, retains human body primitive organism power
Learn, vertebral plate is little with system screw internal stress, and toner screw rate is little.
Refer to Fig. 1 and Fig. 3 again, vertebral plate fixing end 11 has semi-circular ends away from the side of inclined-plane ribs 12,
And the width of vertebral plate fixing end 11 successively decreases toward near the side of inclined-plane ribs 12 from semi-circular ends.
In the present embodiment, a supporter is extended obliquely near vertebral plate fixing end 11 position in the bottom surface of inclined-plane ribs 12
5, and supporter 5 forms a class tiger's jaw shape bayonet socket with vertebral plate fixing end 11 and inclined-plane ribs 12.
In the present embodiment, a projection is extended straight down near lateral mass fixing end 13 position in the bottom surface of inclined-plane ribs 12
Block 6, and raised block 6 runs through the whole width of inclined-plane ribs 12.Raised block 6 is that the bottom surface of inclined-plane ribs 12 extends
It is raised that line intersects formed acute angle with vertical direction.
In the present embodiment, development mark 2 is two, one of in vertebral plate fixing end 11 and straight positioned at two
The side of exhausting hole 111 line of centres;Other in which is located in lateral mass fixing end 13, and is located in two horizontally-arranged through holes 131
The side of heart line.
In the present embodiment, the length of development mark 2 is 1.1mm~1.3mm, preferably 1.1mm.That is, development
The length of mark 2 is more than the thickness of vertebral plate fixing end 11, also greater than the thickness of lateral mass fixing end 13.

Material is made.Because polyetheretherketonematerials materials have excellent biocompatibility, with human body no rejection, postoperative minimizing is secondary to be made
With long-term effect is good.
In the present embodiment, development mark 2 is made using medical titanium.
The using method of spinal lamina bridge system of the present utility model is: appears spinal lamina through the way of escape, it is first determined
Laminectomy side and hinge side, the preparation of first hinge side: only stay spongy bone and internal layer cortex, form bone groove;Laminectomy side is accurate
Standby: the vertebral plate of incision progressively to be lifted upwards, to door-hinge side, forms " enabling " until canalis spinalis is extended to satisfaction, determine institute
Need main body specification, then select the fixed plate main body 1 of suitable length;Class tiger's jaw shape bayonet socket is carried, by vertebral plate in fixed plate main body 1
Imbed in class tiger's jaw shape bayonet socket, upwardly vertebral plate, then the lateral mass fixing end 13 of fixed plate main body 1 is placed on lateral mass surface,
Raised block 6 props up side block edge.After fixed plate main body 1 positioning, in line through hole 111 in be aligned fixed plate main body 1, horizontally-arranged logical
Punching on bone face in hole 131, chooses the short bone nail 3 and long nail 4 of suitable length, is screwed in line through hole 111 and horizontally-arranged logical respectively
Hole 131, fixed plate main body 1 is fixed on vertebral plate and lateral mass, completes to fix.So far, then complete this spinal lamina bridge system
Implantation.
Can be seen that the bayonet socket based on vertebral plate fixing end 11 for this utility model and lateral mass fixing end 13 from using method above
Raised block 6 design and expand canalis spinalis, recover vertebral canal volume, protection rear so that instant support can also be played in system art
Effect, postoperative apply long-term Auxiliary support power, effectively preventing enabling canalis spinalis from expanding, Laminoplasty is postoperative closes the door again, operation behaviour
Make simple and practical, reliable, safely, effectively.
