So that flicking outward in the middle part of first steel plate and second steel plate, the first steel plate of control and the second steel are rotated by interior bar
Spacing between plate, so that the elastic force for hooking pawl is adjusted, the aperture of first steel plate and the mobile pear-shaped hole of second steel plate
Thin rod part is slided into, the hook pawl, which inwardly squeezes, increases fracture pressure.This kind of bilateral fixing steel plate passes through two pieces of fixing steel plates
It will be wrapped up from femoral fracture from two sides and penetrate lock screw and fixed, the lock screw at middle part may make two after being fully screwed into
Block fixing steel plate flicks and passes through the hook pawl at both ends and will compress at femoral fracture, guarantees surgical effect.
In above-mentioned technical proposal, it is preferred that shape on the outside of the threaded hole and the pear-shaped hole on second steel plate
At there is a protection cavity, the end of first positioning screw and second positioning screw is located in the protection cavity.Using
The end of structural defence first positioning screw and the second positioning screw, prevents the end of the first positioning screw and the second positioning screw
Portion penetrates into muscle.
In above-mentioned technical proposal, it is preferred that any one group of hardy hole cooperated with second positioning screw
Line be not parallel to each other.Using the structure the first steel plate and the second steel plate are not easily disconnected from when by unidirectional force.
The utility model compared with prior art, has the following beneficial effects: this kind of bilateral fixing steel plate in use, described
The hook pawl hooks at the first steel plate and second steel plate both ends live femur, and first steel plate and second steel plate are inwardly suppressed
And first positioning screw is penetrated, the threaded hole on the external screw thread and the first steel plate on outer tube cooperates, the external screw thread in interior bar
Cooperate with the threaded hole on the second steel plate, the second positioning screw is penetrated in the macropore of the pear-shaped hole until thin rod part and institute
Pear-shaped hole matching is stated, the interior bar for turning the first screw at this time makes first steel plate and second steel plate middle part outside
It flicks, the spacing between the first steel plate of control and the second steel plate is rotated by interior bar, so that the elastic force for hooking pawl is adjusted, described first
Steel plate and the aperture of the mobile pear-shaped hole of second steel plate slide into thin rod part, and the hook pawl, which inwardly squeezes, increases fracture pressure
Power.This kind of bilateral fixing steel plate will be wrapped up from femoral fracture from two sides by two pieces of fixing steel plates and penetrate lock screw and fixed,
The lock screw at middle part may make two pieces of fixing steel plates to flick after being fully screwed into and pass through the hook pawl at both ends for femoral fracture
Place compresses, and guarantees surgical effect.
