The corresponding tooth of body groove 711 prominent 7231.When compacting part 723 promotes compacting part 723 to close to the movement of the direction of drag hook 710, tooth
Prominent 7231 can be effectively embedded into coupler body groove 711, allow what drag hook 710 stablized to be clamped.Tooth prominent 7231 is netted knot
Structure.
First rod member 401 is identical with the structure of the second rod member 402, and is stock；Each clamping part 300 includes clamping
Set and adjusting part；
Gripping sleeve includes body of rod connecting portion 310 and the cylinder connecting portion 320 being connected with body of rod connecting portion 310, body of rod connection
Portion 310 is provided with the body of rod through hole 311 passed through for corresponding stock, and cylinder connecting portion 320 is provided with follows closely sleeve for corresponding root
There is separation trough 312, separation trough 312 is by body of rod connecting portion 310, edge on the 200 cylinder through holes 312 passed through, body of rod connecting portion 310
The direction in the same direction with the axial direction of stock and be divided into body of rod block 313 and regulation block 314, separation trough 312 and cylinder connecting portion
320 connections, the axis of body of rod through hole 311 is vertical with the axis of cylinder through hole 312；
There is body of rod protuberance 410 and body of rod screens portion 420, body of rod protuberance 410 withstands body of rod block 313 on stock,
The part in regulation block 314 of the body of rod through hole 311 is the screens hole portion 3141 for the insertion of body of rod screens portion 420；
Adjusting part is installed on the end of the remote supporting plate 500 of stock, and adjusting part driving regulation block 314 is to close to body of rod block
313 direction or the direction movement away from body of rod block 313.
The cylinder through hole 312 of cylinder connecting portion 320 is enclosed on root nail sleeve 200, the body of rod through hole of body of rod connecting portion 310
311 are enclosed on stock, and due to the setting of separation trough 312, adjusting part driving regulation block 314 is to close to body of rod block 313
When direction is moved, the thrust increase of 312 pairs of root nail sleeves 200 of cylinder through hole, cylinder through hole 312 stably clamps root nail sleeve
200.When needing to pull down gripping sleeve from root nail sleeve 200, adjusting part driving regulation block 314 is to away from body of rod block
313 direction movement, the thrust of 312 pairs of root nail sleeves 200 of cylinder through hole reduces, easy to disassemble.
Moved for the ease of adjusting part driving regulation block 314, adjusting part includes clamping actuator 330 and projectile
340；Actuator 330 is clamped, is installed on the end of remote supporting plate 500 of stock, and can be moved along the axial direction of stock
It is dynamic；Projectile 340, is sheathed on stock, and between regulation block 314 and clamping actuator 330；Clamp actuator 330
It can be moved by the driving regulation block 314 of projectile 340.
In the present embodiment, actuator 330 is clamped provided with clamping internal thread 331, the one of the close clamping actuator 330 of stock
End is provided with spring 350 provided with clamping external screw thread 430 corresponding with the clamping internal thread 331 between projectile 340 and stock,
The two ends of spring 350 are born against in projectile 340 and regulation block 314；Rotated when clamping actuator 330, and clamp driving
When part 330 drives projectile 340 to close to the movement of the direction of adjusting part, projectile 340 promotes regulation block 314 to clamp root nail
Sleeve 200, now spring 350 shrink；Rotated when clamping actuator 330, and clamp actuator 330 to the side away from adjusting part
To during movement, clamp actuator 330 and the pressure that projectile 340 applies is gradually reduced, until clamping actuator 330 and projectile
340 separate, and now spring 350 stretches.
One end of the close regulation block 314 of projectile 340 adjusts the close of block 314 provided with end tooth portion 341 is promoted
One end of projectile 340 is provided with adjustable side teeth portion 3142, promotes end tooth portion 341 and adjustable side teeth portion 3142 corresponding；The structure
It is easy to clamp after root nail sleeve 200, is completely fixed the position of regulation block 314, when can also make the stretching, extension of spring 350, promotes
End tooth portion 341 and adjustable side teeth portion 3142 easily depart from.
Because the part in regulation block 314 of body of rod through hole 311 is the screens hole for the insertion of body of rod screens portion 420
Portion 3141, so when root nail sleeve 200 is not clamped, the cylinder through hole 312 of two gripping sleeves remains at two stocks
Between, that is, the cylinder through hole 312 of two gripping sleeves is in operating position excessively, and this would not cause to be stranded to the use of doctor
Disturb.
Second rod member 402 is hinged with mediation member 600.Fixed in mediation member 600 and the position of supporting plate 500
Afterwards, it is easy to the placement of dilator.
The end away from the first rod member 401 of supporting plate 500 is provided with travel limit member, exists for limiting actuator 610
Shift motion in supporting plate 500.
Pyramidal support device assembly, in addition to two fix bars 800, each fix bar 800 follow closely sleeve 200 through root, by root
Nail sleeve 200 is connected with corresponding pedicle nail 100.In the present embodiment, pedicle nail 100 is provided with rivet nut internal thread 110, Gu
Fixed pole 800 is provided with body of rod external screw thread 810 corresponding with the rivet nut internal thread 110, the insertion pedicle nail 100 of fix bar 800
End be provided with cylindrical portion 820, pedicle nail 100 be provided with location division 120 corresponding with the cylindrical portion 820, the location division
120 be interior hexagonal through hole, and the inscribed circle of interior hexagonal through hole is corresponding to the size of cylindrical portion 820, and cylindrical portion 820 can
Snap into interior hexagonal through hole；The structure makes pedicle nail 100, fix bar 800 and root nail sleeve 200 coaxial, forms one
Individual firm entirety, it is to avoid the unnecessary component on other directions is produced to pedicle of vertebral arch during strutting.
In the present embodiment, the in the vertical direction of pedicle nail 100 has two flat faces 130 being oppositely arranged, root nail set
The inside of cylinder 200 is provided with flat part 210 corresponding with the flat face 130, and flat part 210 is enclosed on flat face 130, to prevent root
Follow closely the rotation of sleeve 200；The side of root nail sleeve 200 is provided with long lumbar hole 220, and the structure is easy to see clearly the fixation in insertion process
Bar 800, while beneficial to postoperative cleaning and sterilizing.
As shown in Figure 16 to Figure 20, the application method of the pyramidal support device assembly of the present embodiment comprises the following steps：
1) two pedicle nails 100 are squeezed on two neighbouring pedicles of vertebral arch of the ridge gap for the backbone for needing to strut；
2) a root nail sleeve 200 is respectively inserted on two pedicle nails 100；
3) corresponding fix bar 800 is screwed into pedicle nail 100 after packaging root nail sleeve 200；
4) the cylinder through hole 312 of two gripping sleeves of dilator is respectively fitted over into two roots to follow closely after sleeve 200, adjusting part
Clamping cover locking root is set to follow closely sleeve 200, the knob 611 rotated on dilator can carry out strutting operation；
5) drag hook 710 of different size can be clamped after the completion of strutting on coupler body deck 720, so as to backbone with
The vertical side of supporting plate 500 opens up the visual field.
Step 5) complete afterwards and strut operation, doctor broad view, strut it is highly stable in the case of carry out subsequently
Operating procedure.
The present invention need not carry out extra contact with sick body, and prevented to cause sufferer other wounds and complication can
Can property；The present invention will not cause any operation technique for blocking, facilitating doctor's progress follow-up to the visual field of ridge gap approach；This hair
It is bright quick for installation rapid, operating time is shortened, while easy to disassemble and cleaning and sterilizing.Doctor broad view, strut height
