Specifically, guider 20 includes fairlead, fairlead is provided with for bone cavity bores 80 pilot holes 21 guided,
Being provided with installation through hole 11 in main body 10, fairlead is removably mounted in installation through hole 11.During installation, staff will lead
It is arranged in installation through hole 11 to set, starts bone cavity and bore 80, bone cavity brill 80 is stretched into from pilot hole 21, pre-to spinal joints head to be drilled
Location is put and is carried out boring chamber.Certainly, in order to improve the accuracy boring chamber of the present invention, the position of the pilot hole 21 of the present invention further
The exact position installing through hole 11 can also be determined, naturally it is also possible to combine existing on this basis by computer-aided design
Some osteotomy forming techniques improve the accuracy of location division and pilot hole, above scheme all the application protection domain it
In.It addition, be directed between set and main body 10 be arranged to detachably, once bone cavity bores 80 and has damaged fairlead, can be only to leading
It is replaced to set rather than integral replacing, effectively reduces replacement cost.
Seeing shown in Fig. 2 and Fig. 3, the one end away from spinal joints head to be drilled installing through hole 11 in the present invention is provided with location
Groove 12, fairlead includes positioning section 22 and guide section 23, and positioning section 22 is suitable with locating slot 12, guide section 23 and installation through hole
11 is suitable.During installation, the section of being directed to is arranged in installation through hole 11, and now, positioning section 22 is fastened in locating slot 12, makes to lead
Can not be near the motion of the direction of spinal joints head to be drilled to section, during work, bone cavity bores 80 from positioning section 22 and guide section 23
Pilot hole 21 stretches into, and carries out spinal joints head to be drilled boring chamber through installing through hole 11.
In order to improve the brill chamber precision of the present invention, prevent bone cavity from boring in the course of the work and drive fairlead to rotate together, shadow
Ring the guiding accuracy of fairlead, it is preferable that on the inwall of the locating slot 12 in the present invention, be provided with multiple fixture block 13, positioning section
22 be circumferentially provided with multiple draw-in groove 221, fixture block 13 is suitable with draw-in groove 221.During installation, multiple fixture blocks 13 are pacified one to one
Being contained in multiple draw-in groove 221, during work, fairlead blocks fixture block 13 by draw-in groove 221, it is therefore prevented that the rotation of fairlead, and then
Improve the guiding accuracy of fairlead.

Attach plate 14, attach the side attaching face 142 suitable with the sidewall of osteotomy end 70 that be provided with on plate 14, attach the inner surface of plate 14
On be additionally provided with the just attaching face 141 suitable with the cross section of osteotomy end 70.Staff by the medullary cavity molding of the present invention
During device is arranged on osteotomy end 70, by the close present invention's in the attaching face, side 142 with osteotomy end 70 that attach plate 14
The sidewall of medullary cavity shaped device coordinates, and the cross section being further advanced by the face that just attaches 141 and osteotomy end 70 that attach plate 14 is joined
Close, make main body 10 can be precisely mounted on osteotomy end 70.Osteotomy end 70 in the present invention can be to obtain after common osteotomy
, it is also possible to being the osteotomy end obtained with existing osteotomy forming technique by computer-aided design, the latter is with the present invention's
Attach plate 14 to combine use, the positioning precision of the location division of the present invention can be improved further.
In order to make more stable being arranged on osteotomy end 70 of the main body 10 in the present invention, medullary cavity shaped device also includes
Fixing bar 30, attaches and is provided with fixing hole 15 on plate 14, and fixing bar 30 is suitable with fixing hole 15.During work, by fixing bar 30
It is connected on the outer surface of osteotomy end 70 through fixing hole 15, the outer surface of osteotomy end 70 is formed certain pressure, so that fixed
Position portion is more firmly secured on osteotomy end 70.The fixing bar 30 of the present invention can be threaded rod, and corresponding fixing hole 15 is
Screwed hole, during work, inserts fixing bar 30 by the way of screwing, and makes all to fix bar 30 by the self-locking of screw thread and support all the time
It is connected on the outer surface of osteotomy end 70, it would however also be possible to employ in the mode of osteotomy end boring, fixing bar 30 is inserted fixing by staff
Boring on the sidewall of hole 15 and osteotomy end, fixing with realization body 10.
In order to further enhance the stability that main body 10 is arranged on osteotomy end 70, fixing hole 15 and fixing bar 30 are many
Individual.During work, multiple fixing bars 30 are inserted in fixing hole 15 correspondingly, press the sidewall surfaces of osteotomy end 70, so that
Main body 10 is more stably fixed on osteotomy end 70.
Shown in Figure 5, in the second embodiment of the present invention, the precalculated position in the present invention is condyle of femur 60, main body
10 are arranged on condyle of femur 60, and location division includes that location-plate 40, location-plate 40 are fastened in the depression 61 of condyle of femur 60.Install
Time, location-plate 40 is arranged in the depression 61 of condyle of femur 60, this depression can be the depression naturally of condyle of femur, it is also possible to be logical
Cross computer-aided design coordinate existing condyle of femur forming technique to make artificial depression that condyle of femur formed, the most above-mentioned where
A kind of depression, the main body in the present invention can make main body 10 more be precisely located by location-plate 40 with coordinating of depression 61
On condyle of femur.
Shown in Figure 5, in order to improve the positioning precision of the location division in the present invention further, it is preferable that in the present invention
Location division also include that detent 41, detent 41 are arranged on the both sides of location-plate 40, detent 41 and condyle of femur 60
Rat suitable.This rat can be that the natural surface of condyle of femur self is protruding, it is also possible to is to pass through computer
Aided Design coordinates the rat that existing condyle of femur forming technique makes condyle of femur be formed, and during work, is covered by detent 41
It is located on the rat of condyle of femur 60, so that location division is fixed on condyle of femur more accurately, and then is allowed to rear bone cavity brill
80 stretched into and bore the process in chamber by fairlead more accurate, reduces bone cavity and bores the probabilities of 80 generation fine motions.
