Bone wing filling prosthesis 100 includes: prosthese ontology 1, prosthese ontology 1 include for the surface at the bony defect of human body alaossisilii
Connected bone contact surface 11, the soft tissue contact surface 12 being connected for the soft tissue with human body, and the ilium with human body alaossisilii
The crestal surface 13 that the outer edge of ridge engages；Three-dimensional porous structure sheaf 2, three-dimensional porous structure sheaf 2 be formed in bone contact surface 11 and/or
On soft tissue contact surface 12 and/or crestal surface 13；At least one fixing piece 3 (as shown in Figure 3), fixing piece 3 sequentially pass through crestal surface 13
It is connected with bone contact surface 11 with the alaossisilii of human body, prosthese ontology 1 is fixed on the alaossisilii of human body.
Alaossisilii filling prosthesis 100 of the invention when in use, uses osteotomy tool as shown in Figure 4 to alaossisilii first
Edge carry out taking bone, taking at bone is at bone defect of the present invention, according to the shape at the bone defect to the present invention
Alaossisilii filling prosthesis 100 1 being customized of prosthese ontology it is tailor-made, make the bone contact surface 11 and the bone of prosthese ontology 1
The bony surface of defect point matches, and the soft tissue contact surface 12 of prosthese ontology 1 is configured to and soft group at the bone defect
It knits that contact surface is identical, while prosthese ontology 1 being fixed on the alaossisilii of human body by fixing piece 3, so as to complete the present invention
Filling of the alaossisilii filling prosthesis 100 to the defect point of the alaossisilii of human body.
Alaossisilii filling prosthesis 100 of the invention is on bone contact surface 11 and/or soft tissue contact surface 12 and/or crestal surface 13
It is formed with three-dimensional porous structure sheaf 2.By the setting, so that alaossisilii filling prosthesis 100 of the invention has following several respects
Benefit:
1) metaplasia is customized by the prosthese ontology 1 to alaossisilii filling prosthesis 100 to produce, prosthese ontology 1 can be made more suitable
The shape for answering the fault location of the alaossisilii of patient makes the alaossisilii of human body can after filling by alaossisilii filling prosthesis 100
The symmetry for preferably obtaining the alaossisilii of the left and right sides, to effectively improve the filled aesthetic effect of alaossisilii；
2) three-dimensional porous structure sheaf 2 makes bone contact surface 11 be provided with the contact area bigger with alaossisilii sclerotin, i.e. bone connects
The outer surface of contacting surface 11 obtains better Bone Ingrowth ability, and ilium sclerotin can quickly be grown into porous structure, to help
In the fixation that the alaossisilii of alaossisilii filling prosthesis 100 and human body is stable；
3) three-dimensional porous structure sheaf 2 obtains the outer surface of soft tissue contact surface 12 and/or crestal surface 13 preferably
Bone is creeped ability, and alaossisilii sclerotin can quickly grow into its porous structure along the outer surface of soft tissue contact surface 12 and/or crestal surface 13
In, so that alaossisilii filling prosthesis 100 and the fixation of the alaossisilii of human body are more stable；
4) porous structure is formed in the outer surface of soft tissue contact surface 12 and/or crestal surface 13, additionally it is possible to contact in soft tissue
Face 12 and/or the outer surface of crestal surface 13 rebuild the attachment point of human body soft tissue, so that alaossisilii filling prosthesis 100 and human body
Soft tissue faster merge, to be effectively reduced patient's postoperative recovery time, and it is postoperative to significantly improve patient
Recovery effects.
In preferred embodiment as shown in Figure 1, bone contact surface 11 may include two phases being formed on prosthese ontology 1
Pair side plane 111 and connection two side planes 111 baseplane 112, crestal surface 13 may include be formed on prosthese ontology 1 with
The opposite top surface 131 in baseplane 112, soft tissue contact surface 12 may include connect baseplane 112 and two side planes 111 two
A N-Side surf 121 (as shown in Figure 2) can be formed at least one threaded hole for extending to a side plane 111 on top surface 131
132, fixing piece 3 can be the screw (as shown in connection with fig. 3) that matches with 132 screw thread of threaded hole, the inner surface of threaded hole 132 and/
Or three-dimensional porous structure sheaf 2 can be formed on the outer surface of screw.
By above-mentioned setting, can make to be formed on the inner surface of threaded hole 132 and/or the outer surface of screw (i.e. fixing piece 3)
For porous structure, on the one hand which can increase the frictional force between screw and threaded hole 132, thus make screw with spiral shell
Pit 132 is difficult to deviate from again after cooperating, and then can be improved the stablizing effect of the fixation of alaossisilii filling prosthesis 100；Another party
Face also enables the outer surface of screw and/or the inner surface of threaded hole 132 to obtain the ability that better Bone Ingrowth and bone are creeped,
So that sclerotin can quickly be grown into the three-dimensional porous structure sheaf 2, since sclerotin is easier to grow into the three-dimensional porous knot
In structure layer 2, sclerotin is allowed to provide screw additional fixed function, this just further enhances the fixed effect of screw
Fruit also effectively avoids existing in this way, the stability of the fixation of alaossisilii filling prosthesis 100 can not only be improved further
Have in technology, screw can be due to the double action of the shearing force being subject to and the intracorporal electrochemical corrosion of people in active procedure by patient
There is a phenomenon where the generations that fractures, and metallic foreign body are formed in human body because screw deviates from prosthese to effectively avoid, and make
Occur at its free phenomenon in patient's body, and then effectively avoids and patient is caused to damage.
