Abstract

The invention relates to a method for preparing a bone defect prosthesis, and belongs to the technical field of bone prosthesis preparation. The method comprises the following steps: 1) establishing aprosthesis model: scanning a bone defect part by adopting nuclear magnetic resonance or CT to construct the bone prosthesis model; 2) establishing a fusion region: modifying a region where the bone prosthesis model is attached to the bone defect part of a human body into the fusion region with a porous structure; 3) compiling a printing program; 4) performing printing preparation; 5) printing: printing a first layer along a printing path, performing laser heating melting or electron beam melting, performing solidifying, and then continuously laminating a second layer and a third layer until aTC4 matrix is formed; and (6) spraying: depositing micron-sized Ta powder into the porous structure of the fusion region through vapor deposition or cold spraying or plasma spraying to obtain the bone defect prosthesis. A titanium alloy matrix and a bioactive layer can be quickly and accurately prepared, the fusion level is improved, and meanwhile, the problems of long preparation time and high preparation cost in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of bone prosthesis production, in particular to a method for preparing a bone defect prosthesis. Background technique [0002] A shortage of bone due to disease, trauma, or surgery is called a bone defect. Severe bone defects need to be filled and repaired with bone prosthesis so that the bone can recover its motion function intact. In the prior art, Ti6Al4V (TC4) titanium alloy material is often used to prepare bone prostheses. Due to insufficient affinity with the human body, the binding force with the defect of the human body is insufficient, and its motor function may not be restored. [0003] Tantalum is an extremely desirable biocompatible material. When it is in direct contact with the bones, muscle tissue and liquid of the human body, it can adapt to biological cells, has excellent affinity, and hardly produces stimulation and side effects on the human body. In the prior art, it has been proposed ...
