The invention has the advantages that the direct embedment in bone grafting storehouse is capable of in the invention, to carry out the combination of bone grafting and spinous process,
To simplify operation, reduce surgical wound surface.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram that the present invention uses screw as positioning device；
Fig. 2 is the structural schematic diagram that the present invention uses teeth as positioning device；
Fig. 3 is the structural schematic diagram of outer stationary plates of the invention；
1. internal fixation plate in figure, 2. outer stationary plates, 3. bone grafting storehouses, 4. positioning devices, 5. observation panels, 6. location holes.
Specific embodiment
Fig. 1 is the structural schematic diagram that the present invention uses screw as positioning device, and Fig. 2 is that the present invention uses teeth as fixed
The structural schematic diagram of position device, Fig. 3 is the structural schematic diagram of outer stationary plates of the invention, fixes fusing device between a kind of spinous process,
Including internal fixation plate 1, outer stationary plates 2, bone grafting storehouse 3 and positioning device 4, the internal fixation plate 1 is separately fixed at outer stationary plates 2
The opposite two sides in bone grafting storehouse 3,3 upper and lower ends of bone grafting storehouse are equipped with opening, on internal fixation plate 1 be fixed with positioning on outer stationary plates 2
Device 4.The internal fixation plate 1 and outer stationary plates 2 are parallelogram plate body.The bone grafting storehouse 3 is equipped with observation panel 5, interior
Observation panel 5 is equipped on fixed plate 1 and outer stationary plates 2.The positioning device 4 is screw.The screw pass through internal fixation plate 1 with
Outer stationary plates 2, outer stationary plates 2 are equipped with location hole 6, and location hole 6 is arcuate socket or threaded hole, and screw is equipped with male threaded stub
Taper locking skull screw or domed lower surface bone screws.The positioning device 4 is teeth.Teeth weldering even or one at
Type is on the inner wall of internal fixation plate 1 and the inner wall of outer stationary plates 2.
Embodiment one:
In conjunction with shown in attached drawing 1 and attached drawing 3, an osculum is first opened on backbone outer surface with osteotome, exposes spinous process part.It is planting
Before entering whole device, put filling up autologous bone in bone grafting storehouse 3, then the bone grafting storehouse 3 with internal fixation plate 1 and outer stationary plates 2
It sets between adjacent spinous process, an open at one end and spinous process in bone grafting storehouse 3 fits at this time, another end opening and another spinous process
It fits, and two adjacent spinous process are between internal fixation plate 1 and outer stationary plates 2.
Then drilling is carried out to spinous process until through-hole is formed, then bone screw and cone along the hole on device with drill bit
Shape lock skull screw, which is screwed into spinous process, to be locked, and operation so just completes.
Taper locks the corresponding threaded holes on skull screw and outer stationary plates 2 and closes, when the rivet nut of taper locking skull screw
It after threaded hole, is screwed into threaded hole with externally threaded screw end, so that entire taper locks skull screw
It is threadedly coupled with the realization of outer stationary plates 2, and entire end is all submerged in threaded hole, this connection type is stronger, and table
Face is without protrusion.And the domed lower surface bone screws with arced terminus are matched with arcuate socket, when domed lower surface bone screws
After rivet nut passes through arcuate socket, arced terminus is matched with arcuate socket, and such bone screw can rotate in arcuate socket, and
It will not follow closely extremely onboard.Blood circulation of this connection type than less likely hampering patient affected part, is conducive to the growth in affected part.
And the observation panel 5 on bone grafting storehouse 3, internal fixation plate 1 and outer stationary plates 2 can be used to observe the growth feelings between bone grafting and spinous process
Condition.And internal fixation plate 1 and outer stationary plates 2 are arranged to parallelogram, can preferably be bonded bone, facilitate restoration ecosystem.
Embodiment two:
In conjunction with shown in attached drawing 2, an osculum is first opened on backbone outer surface with osteotome, exposes spinous process part.It is entire in implantation
Before device, filling up autologous bone in bone grafting storehouse 3, then the bone grafting storehouse 3 with internal fixation plate 1 and outer stationary plates 2 placed adjacent
Spinous process between, an open at one end and spinous process in bone grafting storehouse 3 fits at this time, and another end opening is affixed with another spinous process
It closes, and two adjacent spinous process are between internal fixation plate 1 and outer stationary plates 2.
Due to being provided with teeth on end face opposite between internal fixation plate 1 and outer stationary plates 2, teeth are withstood on spinous process,
Spinous process can be thus fixed between internal fixation plate 1 and outer stationary plates 2.
The characteristics of fusing device can be according to operation is fixed between spinous process, can be divided into the fixed fusing device of left spinous process and right spine
Prominent to fix fusing device, the screw thread hole site on outer stationary plates 2 can be interchanged.Whole device can be according to the practical feelings of patient
Condition, selection use upper and lower two bone screws or two taper locking skull screws or bone screw and taper elongated insertion part
Bone screws are used in mixed way to be fixed.This device can simply and effectively be restored to the centrum of people basic physiological curve.
TC4 titanium as defined in the GB/T13810-2007 that bone grafting storehouse 3, internal fixation plate 1, outer stationary plates 2 and screw can use
Alloy material, or using PEEK material as defined in YY/T0660-2008, or using custom materials as defined in 3D printing.
