Embodiment Construction

[0018] In order to better understand the purpose, structure and function of the present invention, an acetabular prosthesis of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 with figure 2 As shown, it is an acetabular prosthesis of the present invention, which is used for implanting in the acetabulum and replacing the bone tumor part, including an inner liner 4 sleeved on the outside of the femoral head ball (not shown in the figure), and the inner The outer sleeve of the liner 4 is provided with the acetabular cup 3, and the inner liner 4 can be rotated between the ball head of the femoral stem and the acetabular cup 3 to adjust the opening size of the acetabular cup 3 to prevent dislocation of the acetabular prosthesis. Wide range of activity angles. Wherein, the outer wall surface of the inner liner 4 and the inner wall surface of the acetabular cup 3 are both smooth surfaces, which...

Abstract

The invention discloses an acetabulum prosthesis, which is used to replace bone tumor in an acetabulum, and comprises an inner liner (4) which is sleeved outside a ball head of a femoral head, an acetabulum cup (3) is sleeved outside the inner liner (4), the inner liner (4) can rotate between a ball head of a femoral stem and the acetabulum cup (3), and the size of an opening of the acetabulum cup (3) is adjusted to prevent the acetabulum prosthesis from dislocating. The acetabulum prosthesis can be combined with an acetabular bone which is arranged in a patient body, is more firm to fix, is large in activity angle range, and is prevented from dislocating. The acetabulum prosthesis can be assembled at random according to situations of different patients, and meets the demands of different patients. The acetabulum prosthesis can protect limbs for patients, meets the demands of different positions of osteotomy in acetabulum surgery of hip joints, is identified with an original acetabulum position of in a patient body and an angle physical line, and can effectively and reliably rebuild functions of bodies.

Description

technical field [0001] The invention relates to a medical prosthesis, in particular to an acetabular prosthesis for replacing bone tumors in the acetabulum of the pelvis. Background technique [0002] Lesions on the pelvis of the human body can cause malignant bone tumors in the pelvis. Bone tumors should be resected. The resection should achieve complete resection of the tumor, minimize the occurrence of complications, and reconstruct reliable and effective functions. [0003] Due to the complexity of resection and reconstruction of pelvic tumors, the patient’s imaging data should be carefully analyzed before surgery to clarify the extent of the tumor’s intraosseous and extraskeletal soft tissue masses. At this stage, many prostheses cannot meet the above-mentioned standards. Contents of the invention [0004] The object of the present invention is to provide an acetabular prosthesis for replacing bone tumors and preventing dislocation. [0005] In order to achieve the a...
