Problems solved by technology

[0002] With the gradual popularity of artificial hip replacement surgery, the problem of how to maintain the stability of the acetabular cup as an implant on the acetabular side has gradually become prominent. The traditional method is to fix the acetabular cup with bone cement. In the acetabular cavity, or fix the acetabular cup with screws, spray alloy powder or bioceramic powder on the surface of the acetabular cup at high temperature, sinter metal microbeads, etc., in order to increase the bonding force between the surface of the acetabular cup and bone, and delay Implant loosening occurs, but degenerative atrophy of bone cells caused by osteolysin caused by long-term wear and tear of the articular surface is still inevitable, so the detachment and loosening of the interface between the acetabular cup and bone is still the cause One of the main reasons why cup implants eventually fail

Embodiment Construction

[0018] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, the bone graft fusion acetabular cup of the present invention is characterized in that a bone graft hole (2) for implanting bone particles is made on the outer surface of the acetabular cup body (1), and the bone graft hole (2) The size, number and shape of the acetabular cup can be designed according to the volume, surface state and strength requirements of the bone graft fusion acetabular cup. The bone graft holes (2) can also be connected to each other by the communicating holes (3), such as Figure 7 In the operation shown, the bone graft hole (2) of the bone graft fusion acetabular cup is filled with autologous or foreign bone fragments (4). After the operation, the external bone tissue penetrates and grows into the bone graft hole (2) ...

Abstract

The invention relates to an atlantoaxial arthrodesis acetabular cup for manually replacing articulatio coxae. Bone grafting holes for grafting smashed bone grains are made on the outer surface of the acetabular cup. The bone grafting holes are interconnected through a communication hole. Autologous or allosome smashed bone grains are filled in the bone grafting holes of the atlantoaxial arthrodesis acetabular cup during the operation and a sclerotin and acetabular cup gomphosis system is formed after the exterior bone tissue permeates and integrally grows with the mashed bone grains filled in the bone grafting holes, therefore realizing the purpose of efficiently preventing the looseness between the prosthesis of the aritificial articulatio coxae acetabular and sclerotin.

Description

Technical field [0001] The invention relates to a bone graft fusion acetabular cup for artificial hip joint replacement. Background technique [0002] With the increasing popularity of artificial hip replacement surgery, the problem of how the acetabular cup is kept stable in the acetabular cavity as an implant on the acetabular side has gradually become prominent. The traditional method is to fix the acetabular cup with bone cement. In the acetabular cavity, or fix the acetabular cup with screws, spray alloy powder or bioceramic powder, sintered metal beads, etc. on the surface of the acetabular cup at high temperature, in order to increase the bonding force between the surface of the acetabular cup and the bone and delay Implant loosening occurs, but osteolysin caused by long-term wear and tear of the articular surface causes degenerative atrophy of bone cells is still inevitable, so the loosening of the interface between the acetabular cup and the bone is still causing the hip...
