To achieve the above object, the utility model provides the following technical solutions: a kind of orthopaedics pelvis bone screw, packet
Include the first screw, card slot, inner bolt hole, screw rod, delivery chute, the second screw, chip space, tungsten carbide coating, aluminum oxide coating
With zirtan film layer, the upper end of first screw inner cavity offers inner bolt hole, the inner cavity of first screw and is located at interior
Card slot is offered on the outside of screw hole, the thread in inner cavity of the inner bolt hole is connected with screw rod, and screw rod is fixedly installed in the second screw
The middle-end of bottom, the middle-end of second screw head offer delivery chute, and the appearance of the second screw, screw rod and the first screw
Face is successively coated with tungsten carbide coating, aluminum oxide coating and zirtan film layer from inside to outside.
Preferably, the bottom of the first screw front surface offers chip space.
Preferably, the delivery chute is cross-shaped configuration.
Preferably, the tungsten carbide coating with a thickness of 20 to three ten five microns, aluminum oxide coating with a thickness of
30 to five ten microns, zirtan film layer with a thickness of 50 to seven ten microns.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model has opened up inner bolt hole in the upper end of the first screw inner cavity, and screw flight is connected to inner bolt hole
Inner cavity in, while by the effect of card slot and delivery chute, people can be met to the independent assortment of the first screw and the second screw
Be used separately demand, effectively increase the fastness that bone screw uses, solve existing bone screw only and have and is single
Fastening effect, can not achieve the connection between two screws, for synthetism work make troubles the problem of.
2, the utility model has successively been coated with carbonization in the outer surface of the second screw, screw rod and the first screw from inside to outside
It is hard that the corrosion-resistant of this bone screw, resistance to oxidation and entirety can be improved in tungsten coating, aluminum oxide coating and zirtan film layer
Degree, extends its service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
