Embodiment Construction

[0020] In order to better understand the purpose, structure and function of the present invention, an acetabular spacer of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 and figure 2 As shown, it is shown as an acetabular block of the present invention, which is used to replace the necrotic part of the acetabular part of the hip joint, including a trabecular bone 1, and a plurality of holes 2 are arranged on the trabecular bone 1, and the holes 2 are arranged according to a certain Arranged in a regular array, the acetabular bone can enter the hole 2 to fuse the trabecular bone 1 with the acetabulum, which promotes the combination of the cell tissue of the acetabulum and the acetabular block, and the acetabular block can be stably implanted in the acetabulum. It should be noted that the range of setting holes 2 covers the entire trabecular bone 1, and a plurality of holes 2 are honeyco...

Abstract

The invention discloses an acetabulum cushion block which is planted into a hip joint acetabulum. The acetabulum cushion block comprises a bone trabecula (1), wherein a plurality of holes (2) are formed in the bone trabecula (1); an acetabular bone can enter the holes (2) for integrating the bone trabecula (1) with the acetabulum. The acetabulum cushion block disclosed by the invention is convenient and flexible for operation, and more practical; the bone ingrowth is good, the prosthesis implantation is stable and the fixation is relatively firm.

Description

technical field [0001] The invention relates to a medical prosthesis, in particular to an acetabular pad for replacing the necrotic part of the acetabulum. Background technique [0002] The acetabular pad is a surgical implant that replaces the acetabular part of the human hip joint. It is mainly used for cases of severe hip defects in the acetabulum in hip replacement surgery. The existing acetabular pad is processed by titanium alloy materials. It has the advantages of convenient processing and high processing cost. [0003] Although the existing acetabular spacer can replace the human acetabulum with bone defects, it is found in actual use that the clinical loosening rate after installation with the human acetabulum is high, resulting in the need for revision surgery again, which brings great harm to the patient. Very great physical pain and financial loss. [0004] The existing acetabular blocks mainly have the following disadvantages: [0005] 1) The surgical install...
