Embodiment Construction

[0046] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0047] In the prior art, the artificial hip joint prosthesis is mainly divided into an acetabular component and a femoral component (including the femoral head). Among them, the acetabular component is usually an ultra-high molecular weight polyethylene acetabular cup (bone cement fixation type) or a metal acetabular cup and an ultra-high molecular weight polyethylene liner arranged inside it (biological fixation type). The femoral component is usually composed of a femoral stem and a metal ball head arranged on its top. The above metal ball head cooperates with the inner ball socket of the ultra-high molecular weight polyethylene lining to form a joint friction surface to realize the rotation ...

Abstract

The invention provides a prosthesis component and a method for manufacturing the same. The prosthesis component comprises a bone bonding layer (10), a ceramic layer (20) and a buffer layer (30). The ceramic layer (20) is arranged above the bone bonding layer (10), and the buffer layer (30) is arranged between the bone bonding layer (10) and the ceramic layer (20). According to the technical scheme, the prosthesis component and the method have the advantage that the problem that a prosthesis component in the prior art is easy to loosen after being implanted into a patient can be effectively solved by the aid of the prosthesis component and the method.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prosthetic component and a manufacturing method thereof. Background technique [0002] At present, in artificial joint replacement, the joint prosthesis usually consists of a metal osseointegration component (such as a metal acetabular cup, a metal tibial tray, etc.) and an ultra-high molecular weight polyethylene friction layer. The two are directly connected or connected together through a locking piece. Among them, the ultra-high molecular weight polyethylene friction layer cooperates with other prosthetic components (such as metal femoral condyles). Over time, normal wear between metal osseointegrated components and other prosthetic components and the UHMWPE friction layer produces microscopic polyethylene debris that can lead to implantation The joint prosthesis loosening seriously affects the quality of artificial joint replacement. Contents of the invention ...
