Description
Technical field
The utility model is related to technical field of medical instruments, and in particular to be a kind of lumbar isthmus repair apparatus.
Background technology
In spondylolysis and spondylolithesis of the lumbar spine prosthesis, the hook system for using at present to implant bed and fracture isthmus due to blocking shadow
Ring bone grafting, thus and be unfavorable for the carrying out of bone grafting, Bone graft healing is bad more, and topmost reason is that U-shaped fixing device is squeezed into
After pedicle of vertebral arch, in upper pitman employing longitudinally connected mode connects and fixes vertebral plate, causes rear isthmus to be blocked, from
And have impact on implant bed bone grafting and bone grafting amount.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of lumbar isthmus repair apparatus, and it can keep away
Exempt from isthmus to be blocked, so as to smoothly complete bone grafting, and fusion fixation conveniently is carried out to it.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of lumbar isthmus repair apparatus, including the first U-shaped fixing device, and one end are fixed on the first U-shaped fixed dress
Put the pitman of side, it is characterised in that the pitman includes cylinder straight section, and one end is connected with the cylinder straight section, the other end
It is provided with the flat parabolic segment of the bindiny mechanism for lateral connection and fixed spinous process.
Specifically, the bindiny mechanism includes being connected with flat parabolic segment and middle part offers the first of screw and pads
Block, is distributed on the first spike of the first cushion block one side edge, and realize consolidating spinous process for coordinating with the first cushion block
The second fixed cushion block；The second cushion block middle part is offered in the position through hole Chong Die with screw, and the second cushion block one side
Portion is uniformly distributed on peripheries with the second spike；First cushion block and the second cushion block be close to the surface configuration of spinous process with spinous process physiological shaped
Shape matches.
Or, the bindiny mechanism includes the second U-shaped fixing device being connected with flat parabolic segment, and through second
U-shaped fixing device and the nail hook laterally squeezed into below spinous process.
Compared with prior art, the utility model has the advantages that：
(1) the utility model is reasonable in design, easy to operate, and it dexterously changes pitman on the basis of existing technology
Shape design, be divided into cylinder straight section and flat parabolic segment two parts, then by set bindiny mechanism, with transverse direction
Mode connect and fix spinous process, so as to can not only obtain bigger implant bed, and fixed stability increases, and
And do not affect canalis spinalis and nerve, be conducive to bone grafting operation and bone grafting after good healing.
(2) when developing bad for spinous process, (i.e. setting two is U-shaped simultaneously using double nail hook structures for the utility model
Fixing device), equally can targetedly realize the fixation of pedicle of vertebral arch, it is to avoid because the model that individual difference needs is not very
Situation about matching somebody with somebody occurs.
(3) in the utility model, the first cushion block and the second cushion block is close to the surface of spinous process and spinous process physiology shape matches,
So as to after the effect for coordinating cushion block, screw and spike, can further improve fixing intensity of the utility model to spinous process.

Specific embodiment
The utility model is described in further detail with embodiment for explanation below in conjunction with the accompanying drawings, and mode of the present utility model includes
But it is not limited only to following examples.
Embodiment 1
As shown in figure 1, the utility model provides a kind of lumbar isthmus repair apparatus, it includes the first U-shaped fixing device
1st, pitman and bindiny mechanism.The pitman includes cylinder straight section 2 and flat parabolic segment 3, wherein, cylinder straight section is 4
The diameter pole of~6mm, and flat parabola 3 is designed using flat, the enhancing of corner is capable of achieving, so as to avoid interior fixation
Shi Fasheng is broken.Described one end of cylinder straight section 2 is fixed on the side of the first U-shaped fixing device 1, the other end and flat parabolic segment
3 one end connection.
Described bindiny mechanism is then connected to the other end of flat parabolic segment 3.As shown in Figure 2,3, in the present embodiment, institute
The bindiny mechanism for stating includes being connected with flat parabolic segment 3 and middle part offer screw 5 the first cushion block 4 (thickness is 2~
3mm, width is 6~8mm), it is distributed on the first spike 6 of the one side edge of the first cushion block 4, and the second cushion block 7；It is described
The middle part of second cushion block 7 offers being uniformly distributed on peripheries with the middle part of the position through hole 8 Chong Die with screw, and the one side of the second cushion block 7
Second spike 9；The surface configuration that the cushion block 7 of first cushion block 4 and second is close to spinous process matches (such as with spinous process physiology shape
Shown in Fig. 1).In the present embodiment, the second cushion block 7 is used to coordinate with the first cushion block to be realized fixing spinous process, and specific practice is：By
One cushion block 4 and the second cushion block 7 are individually placed to the both sides of spinous process, and the through hole in two cushion blocks is alignd with screw, then utilize
Spike on cushion block is hammered into spinous process, is finally squeezed into screw via through hole using fixing screws, you can realized to spinous process
Lock and fixed.Spike average length about 1~1.5mm in the present embodiment, it can hammer into spine during spinous process is locked
It is prominent, and the Position Design mode of the first spike and the second spike can avoid the both sides when hammering into spinous process or being rotated by 90 °
Spike intersects head-on collision, causes cushion block to fix unstable to spinous process.
The present embodiment when in use, the first U-shaped fixing device 1 is fixed in pedicle of vertebral arch, and pitman then is inserted into
In one U-shaped fixing device 1 and it is fixed.Then, the first cushion block 4 and the second cushion block 7 are secured transverse to spinous process both sides,
And align, fixing screws are squeezed into screw via through hole again finally.The present embodiment can set fixed dress U-shaped with first
Put with pitman identical structure, the position for supporting and fixing the second cushion block so that itself and the first cushion block perfect cooperation, and
It is close to spinous process, while the first spike and the second spike will not occur to intersect head-on collision, can so realizes well to the steady of spinous process
It is fixed and fixed, as shown in Figure 1.
Embodiment 2
As shown in figure 4, being with the difference of embodiment 1, the bindiny mechanism includes what is be connected with flat parabolic segment 3
Second U-shaped fixing device 10, and through the second U-shaped fixing device and nail hook (i.e. double nail hook systems for laterally squeezing into below spinous process
System, lower leader pin hook can be traditional hook).The present embodiment be primarily adapted for use in spinous process developmental defect, can not be in spinous process side nailing
Fixed situation.
The utility model structure seems simple, is not readily conceivable that actually, and it passes through cleverly to design so that the waist for designing
Vertebra portion repair apparatus can be perfectly suitable for spondylolysis and spondylolithesis of the lumbar spine prosthesis, so as to well healing after being conducive to bone grafting and bone grafting
Close.Therefore, compared with prior art, the utility model has prominent substantive distinguishing features and significant progress.
Above-described embodiment is only one of preferred embodiment of the present utility model, be should not be taken to limit of the present utility model
Protection domain, it is all body design thought of the present utility model and mentally make have no the change of essential meaning or polishing,
The technical problem that it is solved is still consistent with the utility model, should be included in protection domain of the present utility model it
It is interior.
