Abstract

The invention discloses a 3D-printed hip joint replacement prosthesis. The 3D-printed hip joint replacement prosthesis comprises a hip joint main body and a fixing wing set arranged on the hip joint main body, wherein the hip joint main body is of a bowl shape, a center hole is formed in the center of the hip joint main body, a first connecting hole and second connecting holes symmetrically formed in the two sides of the first connecting hole are formed in a first side of the hip joint main body, and connecting lines of central points of the first connecting hole and the second connecting holes form an isosceles triangle; and the fixing wing set is arranged at the bottom of the peripheral wall of a hip joint main body ring body along the circumferential direction of the hip joint main body. According to the hip joint replacement prosthesis disclosed by the invention, the hip joint main body is fixed to a human skeleton through fixing wings, a screw inlet position of a screw is optimized, the hip joint replacement prosthesis is firmly connected with the skeleton, and the problem of shaking or shifting does not occur after long-term use.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, and more particularly to an artificial hip replacement prosthesis. Background technique [0002] Artificial Hip Arthroplasty uses a wide range in the treatment of hip injuries and poor hip development. At present, the acetabular cups used in artificial total hip joints are used to secure the acetabular cup in the injury position. This lock mode cannot be guaranteed in the stability of the human body. Leading to need surgery again. [0003] Therefore, how to improve the hip-changing prosthesis to stably set in the human body, long-term fixation is not displaced is a technical problem that the technical problems need to be solved by those skilled in the art. Inventive content [0004] In order to solve the above technical problems, the present invention provides a 3D printing hip regulatory prosthesis. [0005] The present application provides a 3D printing hip replacement prosthesis ...
