Description
Technical field
The utility model relates to medical instruments fields, particularly relate to a kind of novel screw for carrying horizontal even fixing piece.
Background technique
It needs to follow closely in cervical vertebra, thoracic vertebrae, lumbar vertebrae, sacral etc. at present in operation fixed in stick, often uses horizontal Lian Yijin
One step increases the stability of interior fixed structure.Traditional horizontal even fixed system, horizontal company is individually designed fixation device, is generally needed
Individually to be fixed on hold-down bars, when in use due to hold-down bars, generally can according to the physiological bending of backbone or it is orthopedic need into
Row bending, and increase the operation difficulty of horizontal fixed surely up after hold-down bars bending, and also be easy to cause horizontal fixed fixed not
Firm situation.There are also designs at present by the way that the nail horizontal company of tail is arranged on the nail tail top of screw, increases for fixing horizontal company
Other devices, such as the nut, the nut that lengthen, what although these modes solved that horizontal company after hold-down bars bending is not fixed easily asks
Topic, but the extended length of nail tail is brought, subcutaneous compressing skin may be protruded in the patient of bodily form syntexis, while needing different
Nut fittings, operation is relative complex, and stability also needs further to be promoted.
Utility model content
It is easy to connect the utility model proposes a kind of novel screw for carrying horizontal even fixing piece, and stability is strong, and can fit
Replacement and fixation for different parts.
The technical solution of the utility model is achieved in that a kind of novel screw for carrying horizontal even fixing piece, comprising: nail
Head and the nail tail with U-type groove, it is described nail tail U-type groove side wall on be fixed with it is horizontal even fixing groove, it is described it is horizontal even fixing groove it is same
Sample is U-shaped, and the direction of opening direction and nail tail U-lag is perpendicular.It further include the pressure bar nut and use for the stick that is locked
In the horizontal even nut for locking horizontal company.By using the horizontal even fixing groove, realization is directly carried out between two nail tails
The fixation of horizontal company.
As the optional mode of the utility model, horizontal even the model size of fixing groove and the model of the U-type groove are big
Small consistent, this situation is suitable for cervical vertebra screw fixing system, and the diameter of horizontal connecting bar is consistent with the diameter of hold-down bars.
As another optional mode of the utility model, the model of the horizontal even fixing groove is than the nail tail U-type groove
Model is small, and which is suitable for chest, waist, sacral screw internal fixing system, because the nail tail U-lag of chest waist sacrum vertebral screw is wider,
The diameter of corresponding hold-down bars is also relatively thick, and the diameter of horizontal connecting bar need not be coarse as the diameter of hold-down bars, i.e., horizontal connecting bar
Diameter is smaller than the diameter of hold-down bars, so the model of horizontal even fixing groove is smaller than the model of the U-type groove.
Further, the nail tail includes long-armed nail tail and galianconism nail tail, can use the structure of the utility model.
Further, when the nail tail is long-armed nail tail, the horizontal even height of fixing groove and the long-armed nail tail
The middle part groove that fractures flush；When the nail tail is that galianconism follows closely tail, the horizontal even height of fixing groove and the galianconism
It is flushed above nail tail.It is capable of providing a relatively higher fixation position, is convenient for being connected and fixed between horizontal company.
Further, the ailhead and it is described nail tail between for uni-axial screws be fixedly connected or the company of steering of multi-axial screws
It connects.It can use the structure of the utility model.
As the mode that the utility model another kind is realized, the horizontal-associate fixing groove is set to a side channel of nail tail U-lag
Replacer is set to the structure on the side wall of nail tail U-type groove at mouthful, also can achieve similar technical effect.
The novel screw for carrying horizontal even fixing piece of the utility model, by directly on the side wall of the U-type groove
Or U-shaped horizontal even fixing groove is set at notch, it can conveniently carry out the fixation of horizontal company, and fixed stability pole
By force.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 4, a kind of novel screw carrying horizontal even fixing piece, comprising: ailhead 2 and the nail with U-type groove
Tail 1 is followed closely and is fixed with horizontal even fixing groove 3 on the side wall of tail U-type groove, and horizontal even fixing groove 3 is similarly U-shaped, and opening direction and nail
The opening direction of tail U-lag is perpendicular.It further include the cross for the pressure bar nut 11 for the stick 5 that is locked and for locking horizontal company 4
Even nut 31.By using horizontal even fixing groove 3, the fixation directly followed closely at two and carry out horizontal company 4 between tail 1 is realized.
As the optional mode of the utility model, the model size of horizontal even fixing groove 3 can be with the model size of nail tail U-type groove
Unanimously, this situation is suitable for cervical vertebra screw fixing system, and the diameter and hold-down bars 5 of horizontal connecting bar 4 are consistent (as shown in Figure 2).
As another optional mode of the utility model, the model of horizontal even fixing groove 3 is smaller than the model of U-type groove, the party
Formula is suitable for chest lumbosacral spine screw internal fixing system, and the diameter of horizontal company 4 is smaller than the diameter of hold-down bars 5 (as shown in Figure 4).
Further, nail tail 1 includes long-armed nail tail (as shown in Figure 2) and galianconism nail tail (as shown in Figure 1), can be used
The structure of the utility model.
Further, it when following closely tail 1 is long-armed nail tail, fractures in the middle part of the horizontal even height of fixing groove 3 and long-armed nail tail
Groove flushes；When following closely tail is that galianconism follows closely tail, flushed above the horizontal even height of fixing groove 3 and galianconism nail tail.It can mention
For a relatively higher fixation position, it is convenient for being connected and fixed between horizontal company 4
Further, between ailhead 2 and nail tail 1 for uni-axial screws be fixedly connected or multi-axial screws turn to connection.Its
The structure of the utility model can be used.
As another optional mode of the utility model, horizontal fixed determines slot position in opening (such as Fig. 5 of nail tail U-type groove
It is shown), it equally can reach identical technical effect.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
