Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of dynamic coxa bone plate of adjustable-angle.
Background technique
Dynamic coxa locking steel plate angle currently on the market is fixed, and is generally divided into 125 °/130 °/135 °/140 °
Equal-specification.And collodiaphyseal angle normal value 132 ° of male's average out to, 127 ° of women average out to, is clinically difficult between 110-140 °
Perfection meets all demands on collodiaphyseal angle degree；In implantation process, after pulling force nail screws in, steel plate position is not fixed easily, drop
Low installation accuracy.
Summary of the invention
For the deficiency of existing product, the present invention provides a kind of dynamic coxa locking steel plate of adjustable angle, which can be with
It adjusts angle and is not less than 20 °, best adjustable range is 125 ° -145 °, covers the range of most of normal collodiaphyseal angle.
The purpose of the present invention is achieved through the following technical solutions:
A kind of dynamic coxa bone plate of adjustable-angle, including gooseneck boom ailhead, intermediate, tail portion, anti-rotation tab, locking nut,
Pulling force nail, pin, angular adjustment nut, stabilizing ring, bail and position-limitting pin；The pulling force, which is bound, fits over the gooseneck boom ailhead
Sleeve in, by pre-perforated in the interior hexagonal precession bone of tail portion；The anti-rotation tab is connected by pin and the gooseneck boom ailhead
It connects, the gooseneck boom ailhead is connect by pin with the intermediate, with the one of the angular adjustment nut in the intermediate
Side is engaged, and the other side of the angular adjustment nut is connected with the stabilizing ring, and the stabilizing ring guarantees angular adjustment nut
Axis does not deviate and moves up and down the angular adjustment nut in the axial direction, and the position-limitting pin can limit α ° most
Big value；The tail portion is fixed on the intermediate by the bail.
Further, the angle adjustable of the dynamic coxa bone plate of the adjustable-angle is not less than 20 degree, i.e., α ° can reach
125°-145°。
Further, the angular adjustment nut is screwed in or is screwed out for adjusting the gooseneck boom ailhead, anti-rotation tab, locking
The angle [alpha] ° of nut and pulling force nail.
Further, the bail not only connect with steel plate but also connect with femoral shaft, and the tail portion can be according to different fracture classes
Type selects the hole 3-15 different size, and pitch-row is 16mm.
Further, it can be placed in one piece of cancellous bone screw in the anti-rotation tab, follow closely to form plane and fix with the pulling force.
Further, angle is adjustable to the anti-rotation tab in the axial direction.
Compared with the existing technology, the features of the present invention and progress are as follows:
Since adjustable-angle bone plate is split modular structure, compared with other product unitary designs, with a product
The product of homologous series different angle specification can be corresponded to, therefore the scope of application is wider, angular adjustment is flexibly bonded in use；Together
When, the adjustable angle anti-rotation tab of gooseneck boom ailhead connection can guarantee the stabilization of installation in the installation process of dynamic coxa, improve
The precision of installation.The dynamic coxa locking bone fracture plate structure of adjustable-angle of the present invention is relatively easy, and operation is simple and reliable for installation, adjusts
It is big to save angular range, can accurately, reliable be connect with bone.
Detailed description of the invention
Fig. 1: the top view of the dynamic coxa bone plate of adjustable-angle；
Sectional view of the dynamic coxa bone plate of Fig. 2: Fig. 1 adjustable-angle along A-A.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figs. 1-2, the dynamic coxa bone plate of a kind of adjustable-angle, including gooseneck boom ailhead 1, intermediate 2, tail portion 3,
Anti-rotation tab 4, locking nut 5, pulling force nail 6, pin 7, angular adjustment nut 8, stabilizing ring 9, bail 10 and position-limitting pin 11.
Pulling force nail 6 is assemblied in the sleeve of gooseneck boom ailhead 1, by pre-perforated in the interior hexagonal precession bone of tail portion.Anti-rotation tab 4 passes through pin
Nail is connect with gooseneck boom ailhead 1, is adjusted after 4 angle of anti-rotation tab is bonded with bone after fixed pulling force nail 6 and is screwed in lock screw
Positioning finally screws in locking nut 5 and reinforces.Gooseneck boom ailhead 1 is connect by pin 7 with intermediate 2, in intermediate 2 and angle
The side of adjusting nut 8 is engaged, and the other side of angular adjustment nut 8 is connected with stabilizing ring 9, and stabilizing ring 9 guarantees angular adjustment spiral shell
The axis of mother 8 does not deviate and moves up and down angular adjustment nut 8 in the axial direction, that is, guarantees angular adjustment nut 8 only
Up and down adjustment, position-limitting pin 11 can limit α ° of maximum value.Tail portion 3 is fixed on intermediate 2 by bail 10, in aforementioned portion
Divide after fixing, tail portion 3 is fixed on femoral trochanter with lock screw.The bail 10 not only connect with steel plate but also with femur involvement
It connects, tail portion 3 can select the hole 3-15 different size according to different classification of fracture, and pitch-row is 16mm, is selected according to the type of fracture
With different hole count specifications.
Further, the dynamic coxa bone plate angle adjustable of the adjustable-angle be not less than 20 degree, i.e., α ° can reach 125 °-
145 °, cover all ranges of human normal collodiaphyseal angle.
Further, angular adjustment nut 8 screws in (or back-out) to adjust gooseneck boom ailhead 1, anti-rotation tab 4, locking nut 5
And the angle [alpha] ° of pulling force nail 6.
Further, it can be placed in one piece of cancellous bone screw in anti-rotation tab 4, fix, play with 6 formation plane of pulling force nail
The anti-rotational effect of neck of femur.
Further, angle is adjustable to anti-rotation tab 4 in the axial direction, it is therefore an objective to prevent cancellous bone screw from cutting out femur
Head, when final locking after angular adjustment is good, lock by locking nut 5.
The installation method of the dynamic coxa bone plate of the adjustable-angle is as follows: angular adjustment nut 8 screws in (or back-out)
To adjust the angle [alpha] ° of gooseneck boom ailhead 1, anti-rotation tab 4, locking nut 5 and pulling force nail 6.After pulling force nail 6 is fixed, in anti-rotation
It is placed in one piece of cancellous bone screw in rotor 4, forms fixed constraint together with pulling force nail 6, then lock by locking nut 5.Finally
Tail portion is fixed with lock screw, posts and fixes dynamic coxa locking bone fracture plate on femoral trochanter.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in spirit of the invention, to embodiment described above
Variation, modification will all fall within the scope of claims of the present invention.
