Title: Noboru Matsunaga: Innovator in Bone-Implant Technology
Introduction
Noboru Matsunaga is a distinguished inventor based in Tokyo, Japan. He is known for his innovative contributions to the field of bone-implant technology. His work has significantly impacted the medical industry, particularly in the development of prosthetic devices.
Latest Patents
Matsunaga holds a patent for a method of making bone-implants. This patent describes a slurry compound prepared by sintering powdery material and a binder, which is press-molded to create a contour for the final product applicable to bone-implants, such as hip prostheses. The molded body undergoes programmed movements of rotation and/or swinging to impart centrifugal force to the sintering particles, directing them toward the inner wall of the mold cavity. The final product, obtained after sintering, features a hollow interior with no communication to the outside. By adjusting the conditions of the rotating and swinging movements, the desired structure or constitution of the final product can be achieved. For instance, larger particles can concentrate near the inner wall to provide a rough, porous surface, while a dense core of sintered fine particles is maintained. Additionally, a hip prosthesis with a ceramic-rich femoral head and a metal-rich stem can be produced through specific programming of the movement conditions.
