It is internally provided with the ball-and-socket for accommodating artificial femur bulb；Described body outer wall is near at the bottom of cup
Part is provided with two joints, and each joint connects with corresponding metal bar；Outside described main body
Wall is provided with some wing pawls near the part of rim of a cup.
Further improvement is that: described joint passes through connector and corresponding metal bar pivot joint.
Further improvement is that: the medial wall of described main body is provided with inside groove, the lateral wall of liner
Being provided with water jacket, snap ring is installed in inside groove and water jacket simultaneously.
Further improvement is that: described body interior has interior tapered cavity, described liner is arranged
In interior tapered cavity.
Further improvement is that: described wing dog collar is around being distributed in the body outer wall part near rim of a cup.
Further improvement is that: described main body and joint are one-body molded.
Further improvement is that: described main body is made up of titanium alloy material.
Further improvement is that: described liner is made up of superhigh molecular weight polyethylene material.
Further improvement is that: described snap ring is made up of titanium alloy or stainless steel material.
The beneficial effects of the utility model are:
1, in this utility model, liner is connected by snap ring and main body are fixing, and liner
It is provided with the ball-and-socket for accommodating artificial femur bulb, it is ensured that acetabular bone metal cup main body and liner
Between locking after will not separate, therefore, its good stability, rotate be less likely to occur to loosen.
2, in this utility model, body outer wall is provided with two joints near the part at the bottom of cup,
Each joint connects with corresponding metal bar, and after connection, metal bar is fixed above to before lumbosacral spine
The pedicle screw that side is fixing.Achieve lumbosacral spine to the successional reconstruction of hip joint, well
Recover waist to conduct to the stress of lower limb, be effectively prevented the upper shifting of artificial semi-pelvis prosthesis
With loosening.
3, in this utility model, body outer wall is provided with some wing pawls near the part of rim of a cup,
Loosening of artificial semi-pelvis prosthesis is further prevented even to come off.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Seeing shown in Fig. 1 and Fig. 2, this utility model embodiment provides a kind of artificial semi-pelvis false
Body, including the acetabular bone metal cup 1 of hemispherical dome structure, acetabular bone metal cup 1 include main body 11 with
And it is arranged at the liner 12 within main body 11, concrete, main body 11 is by titanium alloy material system
Become.Liner 12 is made up of superhigh molecular weight polyethylene material.Main body 11 inside has interior tapered
Cavity, liner 12 is arranged in interior tapered cavity.This liner 12 is by snap ring 13 and main body
11 fixing connections, concrete, snap ring 13 is made up of titanium alloy or stainless steel material.And main body
The medial wall of 11 is provided with inside groove, and the lateral wall of liner 12 is provided with water jacket, and snap ring 13 is same
Time be installed in inside groove and water jacket.
Liner 12 is internally provided with the ball-and-socket 14 for accommodating artificial femur bulb；Ensure that hip
Will not separate after locking between mortar metal cup 1 main body 11 and liner 12, therefore, its stability
Good, rotate and be less likely to occur to loosen.
Main body 11 outer wall is provided with two joints 2 near the part at the bottom of cup, concrete, main body
11 and joint 2 one-body molded.Each joint 2 connects with corresponding metal bar 3；Specifically
, joint 2 is by connector 4 and corresponding metal bar 3 pivot joint.Metal bar after connection
3 pedicle screws fixing to lumbosacral spine front fixed above.Achieve lumbosacral spine to hip joint
Successional reconstruction, has recovered waist well and has conducted to the stress of lower limb, be effectively prevented
