Title: Innovations by Shoichi Wakabayashi in Prosthetic Technology
Introduction
Shoichi Wakabayashi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of prosthetic technology, particularly in the development of materials for bone substitutes. With a total of 2 patents, his work focuses on enhancing the functionality and effectiveness of prosthetic devices.
Latest Patents
Wakabayashi's latest patents include a prosthetic body for bone substitute and a method for its preparation. The inventive prosthetic body is a sintered body of hydroxyapatite characterized by an open pore structure with a pore diameter in a specified range, forming a porosity of 20 to 40% and a bending strength of at least 100 kg/cm². This sintered body can be prepared by blending powders of hydroxyapatite and a thermally decomposable substance, such as crystalline cellulose, each having a specified particle size distribution, in a specified proportion, followed by shaping and sintering the powder blend.
Another significant patent is for a porous hydroxyapatite material for artificial bone substitutes. This sintered microporous hydroxyapatite material is useful as a filling material for lost portions or cavities of bones, either in granular or slurried form in a physiological saline solution. The material is characterized by an open pore structure of micropores with a pore diameter distribution ranging from 0.01 to 0.10 mm and a porosity of 20 to 50%. When used as a granular bone filling, the particle diameter should be between 0.1 to 2.0 mm. For prosthetic bone substitute members, the shaped body should consist of the matrix of the microporous material and pores with a diameter distribution of 0.2 to 2.0 mm.
