Problems solved by technology

Osteolysis exists around the acetabular area after total hip replacement, resulting in a huge bone defect around the acetabular area. Revision surgery is difficult. Conventional acetabular prostheses cannot meet clinical needs, and personalized acetabular prostheses need to be customized for precise repair.

Embodiment 1

[0028] A long-term implanted acetabular prosthesis, such as figure 1 , figure 2 and image 3 As shown, it includes an acetabular cup 51 , an outer frame 11 , an outer bone ingrowth 31 and an inner bone ingrowth 41 . The outer frame 11 is fixedly connected with the outer bone ingrowth body 31, the inner bone ingrowth body 41 is fixedly connected with the outer bone ingrowth body 31, and the acetabular cup 51 is respectively fixed with the outer frame 11, the outer bone ingrowth body 31 and the inner bone ingrowth body 41 connect.

[0029] The exoskeleton ingrowth body 31 comprises a plurality of mutually fixed exoskeleton regrowth blocks 32, the exoskeleton regrowth block 32 is cube-shaped, and the outer bone regrowth block 32 is provided with an outer spherical cavity 33, and the outer spherical cavity 33 runs through six parts of the outer bone regrowth block 32. On the other hand, the adjacent outer spherical cavities 33 communicate with each other. The inner bone ingrow...

Embodiment 2

[0045] An application of a long-term implantable acetabular prosthesis, the long-term implantable acetabular prosthesis in Example 1 is applied to the implantation of a bone tumor prosthesis.

[0046] This embodiment has the following advantages:

[0047] The acetabular prosthesis has high structural stability and bone attachment stability, is suitable for long-term implantation of bone tumor prosthesis, is not easy to be damaged, has a long service life, and reduces the number of revisions and replacements after implantation.

Abstract

The invention discloses a long-term implanted acetabular prosthesis, relates to the technical field of acetabular prostheses, and solves the problem of relatively poor stability. The long-term implanted acetabular prosthesis is technically characterized by comprising an acetabular cup, an outer frame, an outer bone in-growth body and an inner bone in-growth body; the outer frame is fixedly connected with the outer bone in-growth body; the inner bone in-growth body is fixedly connected with the outer bone in-growth body; the outer bone in-growth body comprises a plurality of outer bone in-growth blocks which are mutually fixed; each outer bone in-growth block is provided with an outer spherical cavity; each outer spherical cavity penetrates through six surfaces of the corresponding outer bone in-growth block; the inner bone in-growth body comprises a plurality of inner bone in-growth blocks which are mutually fixed; each inner bone in-growth block is provided with an inner spherical cavity; and each inner spherical cavity penetrates through six surfaces of the corresponding inner bone in-growth block. The stability of the acetabular prosthesis is effectively improved, the advantage of relatively good stability is achieved, and the application of the long-term implanted acetabular prosthesis is facilitated.

Description

technical field [0001] The invention relates to the technical field of acetabular prosthesis, in particular to a long-term implantable acetabular prosthesis and its application. Background technique [0002] In order to reduce the impact on the production and life of patients after bone defect, artificial prosthesis can be implanted at the position of bone defect. Tumor-type artificial joints are also called tumor-type artificial prosthesis, which can be customized according to the patient's tumor condition. Artificial joint replacement can preserve good limb function for patients. Osteolysis around the acetabulum after total hip replacement results in a huge bone defect around the acetabulum. Revision surgery is difficult. Conventional acetabular prostheses cannot meet clinical needs, and personalized acetabular prostheses need to be customized for precise repair. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, ...
