Rate.
Spine nail rod hook system generally comprises tranverse connecting rod and the connection hook being fixed on tranverse connecting rod, and it is by connecting hook
The groove of head catches on nail rod, once occurs nail rod to skid off phenomenon, it is possible that vertebral instability, fixing failed consequence, from
And cause the failure of operation.
Summary of the invention
It is an object of the invention to provide a kind of spine nail rod hook device, to overcome deficiency of the prior art.
For achieving the above object, the present invention provides following technical scheme:
The open a kind of spine nail rod hook device of the embodiment of the present application, including pitman, this pitman is fixed with a ridge
The fixing nail of post, a spinal column universal nail and multiple connection hook, described spinal column is fixed nail, spinal column universal nail, is connected hook and be connected
Being fixed by fixed screw between rod, the side of described connection hook offers the screwed hole coordinated with pedicle nail.
Preferably, in above-mentioned spine nail rod hook device, it is solid with spinal column that described fixed screw realizes pitman from top
Fix between fixed nail, spinal column universal nail, connection hook.
Preferably, in above-mentioned spine nail rod hook device, multiple described connection hooks at least include a side port transverse process hook,
One vertebral lamina hook, a pedicle hook, a upper hang plate hook, a lower hang plate hook and a biasing vertebral lamina hook.
Preferably, in above-mentioned spine nail rod hook device, described fixed screw top offers flat recess.
Preferably, in above-mentioned spine nail rod hook device, described connection hook nose thickness 6.0mm ± 1.
Preferably, in above-mentioned spine nail rod hook device, described spinal column universal nail can 360 degree of multiple directions angle twist
Enter vertebral body.
Preferably, in above-mentioned spine nail rod hook device, described spinal column is fixed the screw thread of nail and spinal column universal nail and is used
Double thread designs.
Preferably, in above-mentioned spine nail rod hook device, described pitman, spinal column fix nail, spinal column universal nail, connection
Hook material is titanium alloy.
Compared with prior art, it is an advantage of the current invention that:
This spine nail rod hook device simple in construction of novel offer, safety height, be suitable for clinical demand, subtract to greatest extent
The interference of few soft tissue.The fixing nail of spinal column and spinal column universal nail can be made in use to be quickly screwed, it is possible to reach more firmly to connect
Connect the purpose of spongiosa and cortical bone, additionally, vertebral lamina hook side is provided with screwed hole, vertebral lamina hook can be made to efficiently locate, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 show the structural representation of spine nail rod hook device in the specific embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out detailed retouching
State, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained on the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Shown in Fig. 1, spine nail rod hook device, including pitman 1, this pitman 1 is fixed with a spinal column and fixes
Following closely 2, spinal column universal nail 3 and multiple connection hook 4, spinal column is fixed nail 2, spinal column universal nail 3, is connected hook 4 and pitman 1
Between fixed by fixed screw 5, the side connecting hook 4 offers the screwed hole 41 coordinated with pedicle nail.
Further, fixed screw 5 realizes pitman 1 and fixes nail 2, spinal column universal nail 3 with spinal column, is connected hook 4 from top
Between fixing.
Further, multiple connection hooks 4 at least include a side port transverse process hook 43, pedicle of vertebral arch of 42, vertebral lamina hook
The upper lower hang plate hook 46 of 45, one, hang plate hook of 44, one, hook and a biasing vertebral lamina hook 47.
Further, fixed screw 5 top offers flat recess.
Preferably, hook 4 nose thickness 6.0mm ± 1 is connected.
Further, spinal column universal nail the angle of 360 degree of multiple directions can be screwed into vertebral body.
