As shown in Figures 1 to 10, the acetabular cup of embodiment one includes：Acetabular cup 10, filling block 20 and fixing piece 30.
Acetabular cup 10 includes acetabular cup main body 11 and the guiding fixed part 12 being arranged in acetabular cup main body 11.Filling block 20 includes filling
Block main body 21 and the auxiliary section 22 being arranged in filling block main body 21, auxiliary section 22 are engaged with guiding fixed part 12.Fixing piece
30 are engaged with acetabular cup 10 and filling block 20 and acetabular cup 10 and filling block 20 are fixed on bone.
The technical solution of Application Example one, the guiding fixed part 12 of acetabular cup main body 11 and the auxiliary section 22 of filling block 20
It is engaged so that acetabular cup main body 11 is combined together with filling block 20, and fixing piece consolidates acetabular cup main body 11 and filling block 20
It is scheduled on together, and acetabular cup main body 11 and filling block 20 are fixed on bone by fixing piece 30 together, such acetabular cup main body
11 and 20 self structure of filling block be engaged, acetabular cup main body 11 and filling block 20 are fixed together while fixed by fixing piece 30
On bone.The connection that the technical solution of embodiment one efficiently solves filling block and acetabular cup and bone in technology is consolidated
The problem of determining.
As shown in Figures 1 to 10, in the technical solution of embodiment one, guiding fixed part 12 is to be arranged on acetabular cup main body
Convex ribs on 11 outer wall, auxiliary section 22 are the groove being arranged on the inner wall of filling block 20.Said structure is easily worked, and is made
Cost is relatively low.Such as the structure that guiding fixed part 12 and acetabular cup main body 11 are integrally formed.It is recessed on the inner wall of filling block 20
Slot is injection molding, and such processing is more convenient, and the comparision of production of product is fast.
Shown in Fig. 1 to Fig. 6, in the technical solution of embodiment one, guiding fixed part 12 is to be arranged on acetabular cup main body 11
Outer wall on convex ribs, auxiliary section 22 is to be arranged on groove on the inner wall of filling block 20, convex ribs along acetabular cup 10 rim of a cup extremely
The bottom of a cup direction extension of acetabular cup 10.Such structure easily causes acetabular cup main body 11 and filling block easily to coordinate, acetabular cup
It is easy for installation between main body 11 and filling block 20.
As shown in Figures 1 to 6, in the technical solution of embodiment one, convex ribs are multiple, and two convex ribs are oppositely arranged and shape
Into one group, groove is multiple and is set correspondingly with multiple convex ribs.Convex ribs are multiple, and groove is a pair of with multiple convex ribs one
Ground is answered to set multiple, such convex ribs can realize filling block 20 limitation of various dimensions, and to the limitation ratio of filling block 20
Stronger, convex ribs are less likely to occur to damage.
As shown in Figures 1 to 10, in the technical solution of embodiment one, filling block 20 include the first end that is oppositely arranged and
Second end, groove penetrates through the first end and second end of filling block 20, so that filling block 20 is slipped into acetabular cup 10 by groove
Convex ribs.The installation of so filling block 20 is more convenient, convenient.Certainly, as one skilled in the art will appreciate that filling block 20 it is recessed
It is also possible that slot is directly mounted to convex ribs.
As shown in Figures 1 to 10, in the technical solution of embodiment one, convex ribs compared with acetabular cup main body 11 outside wall surface
It is obliquely installed.So convex ribs can realize filling block 20 /V of various dimensions, for example, filling block 20 is compared with acetabular cup main body
11 can only realize the slip along convex ribs, without the opposite of the other positions between filling block 20 and acetabular cup main body 11
It is mobile.
As shown in Figures 1 to 10, in the technical solution of embodiment one, formed spacing between one group of two convex ribs from
The distance that the root of convex ribs to free end becomes larger is less than the distance of the end of corresponding two convex ribs.Such structure one
Aspect ensure that the relative movement between filling block 20 and acetabular cup main body 11, and structure as another aspect is easy to process.Tool
Body, two convex ribs form the structure of dovetail groove.
As shown in Figures 1 to 9, in the technical solution of embodiment one, convex ribs are multigroup, and filling block 20 is and multigroup convex ribs
It is one-to-one multiple.The flexible arrangement of filling block 20 can be so realized, for example, can be with when bone defects are more
Multiple filling blocks 20 are set.Certainly, as one skilled in the art will appreciate that the shape of filling block 20 can also flexibly be set, example
It such as could be provided as arc-shaped or plane structure.
As shown in Figure 7 to 10, in the technical solution of embodiment one, fixing piece 30 is screw, is set on filling block 20
There is screw hole 23 matched with screw.The setting of fixing piece 30 limits filling block 20 can be along the opposite freedom slided of convex ribs
Degree.Specifically, screw hole 23 is arranged between two convex ribs in adjacent one group.Further specifically, two in one group
Two screw holes 23 are set between convex ribs.Certainly, as one skilled in the art will appreciate that basis between two convex ribs in one group
It needs that multiple screw holes 23 can be set.
As shown in Figure 7 to 10, in the technical solution of embodiment one, screw includes head of screw 31, the first thread segment 32
With the second thread segment 33, the first thread segment 32 is located between 31 and second thread segment 33 of head of screw, the first thread segment 32 and screw
Hole 23 coordinates, and the second thread segment 33 is engaged with bone, and the second thread segment 33 is the helicitic texture of cancellous bone screw.Second screw thread
Section 33 is the helicitic texture of cancellous bone screw so that the match ratio of screw and bone is stronger, and such screw thread is in sclerotin
Occlusion is fixed, and can have larger resistance to plucking output capacity.First thread segment 32 is normal thread, and such difficulty of processing compares
Low, processing cost is than relatively low.In general, the screw pitch of the second thread segment 33 is more than the screw pitch of the first thread segment 32.
Difference lies in guiding fixed part 12 is to be arranged on acetabular cup main body to the technical solution and embodiment one of embodiment two
Groove on 11 outer wall, auxiliary section 22 are the convex ribs being arranged on the inner wall of filling block 20.
The acetabular cup of embodiment two includes：Acetabular cup 10, filling block 20 and fixing piece 30.Acetabular cup 10 includes acetabular bone
Cup main body 11 and the guiding fixed part 12 being arranged in acetabular cup main body 11.Filling block 20 includes filling block main body 21 and is arranged on
The auxiliary section 22 in block main body 21 is filled, auxiliary section 22 is engaged with guiding fixed part 12.It fixing piece 30 and acetabular cup 10 and fills out
Block 20 is filled to be engaged and acetabular cup 10 and filling block 20 are fixed on bone.
The technical solution of Application Example two, the guiding fixed part 12 of acetabular cup main body 11 and the auxiliary section 22 of filling block 20
It is engaged so that acetabular cup main body 11 is combined together with filling block 20, and fixing piece consolidates acetabular cup main body 11 and filling block 20
It is scheduled on together, and acetabular cup main body 11 and filling block 20 are fixed on bone by fixing piece 30 together, such acetabular cup main body
11 and 20 self structure of filling block be engaged, acetabular cup main body 11 and filling block 20 are fixed together while fixed by fixing piece 30
On bone.The connection that the technical solution of embodiment two efficiently solves filling block and acetabular cup and bone in technology is consolidated
The problem of determining.
