Specific embodiment
A specific embodiment of the invention is made a detailed explanation with reference to the accompanying drawing.
Embodiment one, it is a kind of to for fracture of head of femur when reset dynamic bone screws and bone plate structure combined structure,
It include bone plate ontology 1, fluting 2, two resistance blade 3 of bone nail and fixing screws 4.,
Such as Fig. 1, shown in 2,5,6, bone plate ontology 1 has engaging portion 12, and inside is in cancave cambered surface, it is made to be posted by femur
When, the contact area between the two can be increased；Four perforation 120 penetrate through inside and outside the engaging portion 12, and are separated by suitable distance；
Extension 14 is the tubulose with suitable length, and the outer rim of outboard end is connect with the upper end of the engaging portion 12, and the two
Long axis direction presss from both sides 120 °~140 ° of angle, so that the bone plate ontology 1 is in bending；140 phase of axis hole inside the extension 14
It is greater than inner end person adjacent to the internal diameter of the outboard end of the engaging portion 12, and forms a block at the shoulder of the adjoiner of the two
Portion 142；Two the first limiting sections 144 are respectively the plane set on 140 inner wall of axis hole, and by the outboard end court of the axis hole 140
Interior extension suitable length, and keep the axis hole 140 and the cross section of corresponding position slightly ob-round；Separately there are two the first elongated slots 146
Set on 140 inner wall of axis hole, extend suitable length towards inner end by its outboard end.In this present embodiment, 2 first limit
Portion 144 is set as being separated by 180 degree, and 2 first elongated slot 146 is then recessed in corresponding respectively first limiting section 144 respectively
Place.
The fluting bone nail 2, in the hollow shape with suitable length, outboard end has length appropriate, and with can be along it
The mobile mode of axial reciprocating is placed through in the extension 140, and inner end outer rim is equipped with and attacks murices tooth 20, outboard end
Inner wall is then equipped with internal screw thread 22, and 2 second limiting sections 24 are respectively the plane set on 2 outer rim of fluting bone nail, and by its outboard end
Towards the suitable length that extends internally；2 second elongated slots 26 are recessed in its outer rim respectively, and along its axially extending suitable length, and pass through
At second limiting section 24, and suitable length is extended by its outboard end inwardly；When the bone plate ontology 1 is sheathed on its extension 14
2 outboard end of fluting bone nail it is outer when, respectively first limiting section 144 will be abutted each other with the second limiting section 24, and respectively this first
Elongated slot 146 is then interconnected with the second elongated slot 26.
As described in Figure 8, the two resistances blade 3, for the strip sheet with suitable thickness and width, and cross section is in square
Shape, and can simultaneously in respectively first elongated slot 146 and the second elongated slot 26, inner end equipped with lead angle, to make its
Resistance or disalignment can be reduced during implanted femur, also its front end can be made to be formed as blade shape when necessary；One perforation
Set on its outboard end, to cooperate with other tools, for the two resistances blade 3 being set in femur to be taken out.
The fixing screws 4, inner end can be used to screw togather with the internal screw thread 22 of 2 outboard end of fluting bone nail, outer diameter compared with
Big outboard end is formed with the suitable shape that can cooperate with tools such as a screwdriver or die nuts, and due to the outboard end
Outer diameter, greater than the internal diameter of 140 inner end of axis hole, therefore, by the backstop by the stop section 142, and perseverance quilt when being rotated
Indwelling is at the outboard end of the axis hole 140 of the extension 14.
When operation, first the fluting bone nail 2 is locked in the femoral head of fracture, then with the extension 14 of the bone plate ontology 1
Be inserted in the outboard end of the fluting bone nail 2, and make respectively first limiting section 144 corresponded to each other with the second limiting section 24, to prevent this
Fluting bone nail 2 is in wherein rotating；The engaging portion 12 of the bone plate ontology 1, can again by four fixing glues via the respectively perforation 120 with
It is fixed on femur.
The two resistances blade 3 is embedded in it is facing each other respectively between first elongated slot 146 and the second elongated slot 26, when respectively should
When the length of resistance blade 3 is no more than each length of the elongated slot 146,26, it should be made to submerge the interior of each elongated slot 146,26 completely,
So that its outboard end does not protrude from the outer of the outboard end of the fluting bone nail 2, and inner end then has comparable length and extends to this
Inside femoral head, as shown in Fig. 7, and respectively the resistance blade 3 will be contacted in the inner end of rectangle with femoral head with it, so as to increasing
Add the contact area between the two.In addition, respectively the resistance blade 3 by each second elongated slot 26 protrudes from fluting 2 outer rim of bone nail
Highly, it can be set as being greater than or equal to and attack the height of murices tooth 20, in order to more increasing contact area above-mentioned.
Finally, the fixing screws 4 is taken to be penetrated by 14 outboard end of extension, the outboard end spiral shell of the Yu Qiyu fluting bone nail 2
After connecing, the fixing screws 4 are rotated, and since the outboard end of the fixing screws 4 is stopped by the extension stop section 142, and
Respectively first limiting section 144 is abutted against with respectively second limiting section 24 again, therefore, will be through when operator rotates the fixing screws 4
By the respectively bone plate ontology 1 and fluting bone nail 2, resetted with drawing two corresponding positions of fracture.
As shown in figure 11, by protruding from 4 two sides of fluting bone nail in the two resistances blade 3 of wing, can effectively increase
Add the contact area between the dynamic bone screws and bone plate structure structure and femoral head, can not only promote its anchor effect, may be used also
To reach the effect of reducing sinkage.
There is comparable length in the respectively inner end of the resistance blade 3 outside the extension 14 due to protruding from, in reality
With upper, operator before being inserted in the bone plate ontology 1, can be in close proximity to two of the fluting bone nail 2 in femoral head in advance
Outside two elongated slots 26, it is drilled with strip hole respectively, allows and is extended in the femoral head in the inner end of the two resistances blade 3.
Respectively the setting quantity of the resistance blade 3 and position are optimal embodiment, upper in actual utilization, precisely because not
Quantity can give adjustment as one thinks fit, and it is in planar respectively first limiting section that corresponding respectively elongated slot 146,26, which can also be set to non-,
144 or second limiting section 24 other outer positions.Or resistance blade 3 can also do various change,
Embodiment two, such as Fig. 3, shown in 4,9, shown in resistance blade 3 can cancel, only stay helicitic texture or resistance
Blade 3 does not protrude from axis hole 140.
Embodiment three can also add bolt structure as shown in Figure 10 on the outside of resistance blade 3, as long as can increase the dynamic bone
Contact area and enhancing anchor effect between screw and bone plate structure structure and femoral head, reach the purpose of the present invention, belong to
In the transformable scope of this creation.
