Latest Patents

Ueda holds a patent for a method of making bone-implants. This invention involves a slurry compound prepared by sintering powdery material and a binder, which is then press-molded to create a contour suitable for bone-implants, such as hip prostheses. The molded body undergoes programmed movements of rotation and/or swinging to generate centrifugal force, directing sintering particles 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, Ueda can achieve desired structural characteristics in the final product. For instance, larger particles can concentrate near the inner wall to create a rough, porous surface, while a dense core of fine particles is maintained. This innovative method allows for the production of hip prostheses with a ceramic-rich femoral head and a metal-rich stem.
