The adjustment of mode is fixed in method according to the actual situation.
Summary of the invention:
The purpose of the present invention is to above-mentioned the deficiencies in the prior art, provide a kind of positioning device of implantation material.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
The positioning device of the implantation material of implantation material of the invention, including stable bone fixation portion interconnected and implantation material are fixed
Portion, wherein stable bone fixation portion is U-shaped structure, it again include bottom end and open end, and stablize bone fixation portion and stablize the bone of bone
Body is mutually fixed, and implantation material fixed part is connected with bone fixation portion is stablized, and the head end of implantation material fixed part exerts a force to implantation material, pressure
Plate bolt passes through pressing plate and mutually fixes with the diaphysis for stablizing bone, stablizes bone fixation portion and is arranged between pressing plate and the diaphysis for stablizing bone,
It is exerted a force and is fixed by pressing plate, implantation material fixed part is split type structure with bone fixation portion is stablized, and implantation material fixed part is with bending
Plate structure, implantation material fixed part tail end square crossing setting slot and fixing groove, pressing plate be inserted into slot, press simultaneously
Plate bolt passes through fixing groove, and the width of fixing groove is greater than the shaft diameter of bridge screw and is less than ailhead diameter.
The present invention can also use following technical measures:
Two grooves parallel, bottom is cambered surface are arranged in the corresponding bone side of stablizing of the pressing plate, and it is corresponding to stablize bone fixation portion
Setting is in a groove.
The fixing groove of the implantation material fixed part tail end is U-type groove.
Recess is arranged in the outer edge of the fixing groove, and the head of a nail of bridge screw is correspondingly arranged in the valley.
The head end in the stabilization bone fixation portion and implantation material fixed part is oppositely arranged fixed projection respectively.
The advantages and positive effects of the present invention are:
In the positioning device of implantation material of the invention, implantation material fixed part is separate structure with bone fixation portion is stablized, and implantation material is solid
The aft mounted slot and fixing groove for determining portion can ensure implantation material fixed part and stablize to be stably connected between bone fixation portion, no
It is mobile that position can occur easily, meanwhile, by bridge screw and stablize bone photo it is fixed when can also carry out fine position, so as to
Enough make the fixation position of implantation material more accurate, the later period is also not susceptible to positional shift.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the positioning device of implantation material of the invention；
Fig. 2 is the cross-sectional view of the positioning device of implantation material of the invention.
Specific embodiment
Technical solution of the present invention is described in detail below by way of the drawings and specific embodiments.
As shown in Figure 1 to Figure 2, the positioning device of the implantation material of implantation material of the invention, including stable bone interconnected
Fixed part 1 and implantation material fixed part 2, wherein stable bone fixation portion is U-shaped structure, it again include bottom end and open end, and stablize
Bone fixation portion is mutually fixed with the diaphysis for stablizing bone, and implantation material fixed part is connected with bone fixation portion is stablized, and implantation material fixed part
Head end to implantation material exert a force, bridge screw 4 pass through pressing plate 3 mutually fixed with the diaphysis for stablizing bone, stablize bone fixation portion be arranged exists
Between pressing plate and the diaphysis for stablizing bone, being exerted a force and fixed by pressing plate, implantation material fixed part is split type structure with bone fixation portion is stablized,
Implantation material fixed part is the plate structure with bending, the tail end square crossing setting slot 5 and fixing groove of implantation material fixed part
6, pressing plate is inserted into slot, while bridge screw passes through fixing groove, and the width of fixing groove is greater than the shaft diameter of bridge screw
And it is less than ailhead diameter.
Two grooves parallel, bottom is cambered surface are arranged in the corresponding bone side of stablizing of pressing plate, and the bone fixation portion correspondence of stabilization is set
It sets in a groove, to ensure that pressing plate to the biasing effect for stablizing bone fixation portion, stablizes bone fixation portion and is not easy opposing platen position
It moves.
The fixing groove of implantation material fixed part tail end be U-type groove, when implantation material fixed part is matched with pressing plate bridge screw and
Fixing groove plays the role of orientation direction.
The outer edge setting recess 7 of fixing groove, the head of a nail of bridge screw is correspondingly arranged in the valley, and the bottom of recess is flat
Face, the joint face between bottom and implantation material fixed part surface are cambered surface, so as to be unlikely to bridge screw when fixed
Implantation material fixed part surface excessively is protruded from, is conducive to post-operative recovery.
The head end for stablizing bone fixation portion and implantation material fixed part is oppositely arranged fixed projection 8 respectively, to be more conducive to and bone
Body is mutually fixed.
In the positioning device of implantation material of the invention, implantation material fixed part is separate structure, implantation with bone fixation portion is stablized
The aft mounted slot and fixing groove of object fixed part can ensure implantation material fixed part and stablize to stablize between bone fixation portion to connect
It connects, position will not occur easily and move, meanwhile, fine position can also be carried out by bridge screw and when stablizing bone photo fixation,
So as to keep the fixation position of implantation material more accurate, the later period is also not susceptible to positional shift.It first passes through when use across pressure
The positioning of position is fixed in the bridge screw of plate, then adjusts the position for stablizing bone fixation portion and implantation material fixed part, then lead to
Cross pressing plate to stablize bone fixation portion, implantation material fixed part is locked.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
The right present invention has been described by way of example and in terms of the preferred embodiments, however, being not intended to limit the invention, any technology people for being familiar with this profession
Member can make a little change or modification using the technology contents disclosed certainly without departing from the scope of the present invention, at
For the equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, according to the technical essence of the invention
Any simple modification, equivalent change and modification to the above embodiments, belong in the range of technical solution of the present invention.
