AI Technical Summary
Existing titanium artificial ossicle prostheses are expensive, difficult to personalize, and have insufficient biocompatibility, affecting sound transmission efficiency and stability.
The device is injection molded using PEEK composite material and titanium inlays. The movable rod of some ossicular prostheses is made of titanium, while the disc and joint groove are made of PEEK material. It is combined with peptide-modified polyetheretherketone, modified graphene oxide, carbon fiber and mesoporous bioactive glass, and the bonding force is enhanced by inlay injection molding to achieve customized design.
It improves the biocompatibility and sound transmission performance of the ossicles, reduces the amount of metal used and the cost of the prosthesis, enhances clinical adaptability and postoperative stability, and reduces the risk of inflammatory reactions.
