Abstract

The invention provides a replacement prosthesis of a half hip joint and a surgical tool. The replacement prosthesis of the half hip joint comprises a main body, a joint layer and a guide structure, wherein the main body has an insertion end and a repair end which are oppositely arranged; the insertion end of the main body is inserted in a femoral head, and the main body has a porous structure; thejoint layer is arranged at the repairing end of the main body, and the end face, away from the main body, of the joint layer is curved; and the guide structure is arranged at the insertion end of themain body. Through the technical scheme provided by the invention, the problem that in the prior art, the middle-stage femoral head necrosis cannot be effectively treated can be solved.

Description

technical field [0001] The invention relates to the technical field of prostheses, in particular to a replacement prosthesis and a surgical tool for a half hip joint. Background technique [0002] Femoral head necrosis is a disease caused by bone tissue necrosis and self-repair due to interruption of blood supply to the femoral head, resulting in changes in the structure of the femoral head, resulting in collapse of the femoral head, destruction of cartilage, and ultimately hip joint pain and mobility impairment. Among them, femoral head necrosis is divided into early, middle and late three. Early necrosis of the femoral head can be treated by core decompression, which aims to preserve the patient's femoral head and delay the time of joint replacement. [0003] However, this kind of core decompression method has poor curative effect on femoral head necrosis in the middle stage. If no treatment is carried out, 80% of patients will subsequently suffer from osteoarthritis and ...
