Structure of 3D titanium mesh prosthesis for steel plate

Abstract

The 3D titanium mesh prosthesis structure for the steel plate comprises a titanium mesh prosthesis main body, three main body fixing bands are evenly installed at the center of the titanium mesh prosthesis main body, the titanium mesh prosthesis main body is wound into a cylinder shape, connecting bands are symmetrically installed at the top and the bottom of the titanium mesh prosthesis main body respectively, and communicating holes are formed in the centers of the connecting bands; the titanium mesh prosthesis is printed through the 3D printing technology, personalized customization can be conveniently achieved according to the condition of a patient, the problem that a bone graft is difficult to obtain is solved, meanwhile, mold opening customization is not needed, the production cost is reduced, the joint of the prosthesis and the long bone is pressed and fixed through the fastening mechanism, and the use effect is good. The titanium mesh prosthesis has the advantages that the titanium mesh prosthesis main body and the titanium mesh end head are integrally formed, the situation that the joint of the prosthesis and the long bone falls off is effectively avoided, the mounting stability of the prosthesis is improved, the pore range of the titanium mesh prosthesis main body and the titanium mesh end head is 60-90%, the pore diameter range is 300-600 microns, the porosity is high, a callus can directly grow into a gap conveniently, and the prosthesis and the long bone can be integrated conveniently.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a structure of a 3D titanium mesh prosthesis for steel plates. Background technique [0002] A prosthesis is called a prosthesis in medicine. It is a medical device that replaces a limb, organ or tissue of the human body. Glass eyeballs, etc., the latter are all implanted inside the human body, replacing organs or tissues, such as artificial tendons, artificial heart valves, artificial joints, etc. 3D titanium mesh prosthesis is an implantable restoration for long bones Clinical treatment of segmental bone defects; [0003] The production of prostheses on the market today is complex, and it needs to be individually customized according to the different conditions of the patient, which is time-consuming and labor-intensive, and increases the production cost. After the prosthesis is implanted, the joint between the prosthesis and the long bone is prone to loosening and fallin...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, prostheses on the market are complicated to make, and need to be individually molded and customized according to the different conditions of the patients, which is time-consuming and laborious, and increases the production cost. After the prosthesis is implanted, the joint between the prosthesis and the long bone is prone to loosening and falling off, which reduces the firmness of the prosthesis installation. At the same time, there is a certain rejection reaction between the prosthesis and the patient, and it is difficult for the prosthesis and the long bone to grow. together, reducing the supportive effect of the prosthesis
