Pit matching, penetrated in the macropore of the pear-shaped hole the second positioning screw until thin rod part matched with the pear-shaped hole,
Continue to turn the first screw at this time and the first positioning screw is made to be threaded through threaded hole, at this time first steel plate and second steel plate
Middle part flicks outward, and the aperture of first steel plate and the mobile pear-shaped hole of second steel plate slides into thin rod part, described
It hooks pawl and inwardly squeezes and increase fracture pressure.This kind of bilateral fixing steel plate will be from femoral fracture from two sides by two pieces of fixing steel plates
It wraps up and penetrates lock screw and fix, the lock screw at middle part may make two pieces of fixing steel plates to flick and lead to after being fully screwed into
The hook pawl for crossing both ends will compress at femoral fracture, guarantee 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, two first external thread parts are respectively and on first steel plate and second steel plate
Threaded hole matching penetrates the second positioning screw until thin rod part and the pear-shaped hole in the macropore of the pear-shaped hole
Match, continue to turn the first screw at this time the first positioning screw is made to be threaded through threaded hole, at this time first steel plate and described second
It being flicked outward in the middle part of steel plate, the aperture of first steel plate and the mobile pear-shaped hole of second steel plate slides into thin rod part,
The hook pawl, which inwardly squeezes, increases fracture pressure.This kind of bilateral fixing steel plate is by two pieces of fixing steel plates from two sides by femur bone
It is wrapped up at folding and penetrates 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 will be compressed at femoral fracture by the hook pawl at both ends, guarantee surgical effect.
