Patent number: 9107977Abstract: In a hydroxyapatite to be joined to another hydroxyapatite or a bone by laser machining (machining of the bone and the hydroxyapatite includes irradiation of laser light on the bone and irradiation of laser light on the hydroxyapatite), to prevent occurrence of a fracture in a junction and in a peripheral portion of the junction during laser machining, the present invention provides an optimum weight ratio of a cordierite or quartz glass component mixed in the hydroxyapatite. As a mixing ratio of the cordierite or quartz glass component, the cordierite or quartz glass component is mixed at least at a weight ratio equal to or higher than 25.7%.Type: GrantFiled: October 27, 2011Date of Patent: August 18, 2015Assignees: Mitsubishi Electric Corporation, National University Corporation Hokkaido UniversityInventors: Masaru Kanaoka, Taira Ogita, Shigeru Tadano

Publication number: 20140277455Abstract: An apparatus for integrating bone and implant material and a method for fabricating an implant material are provided. The apparatus includes a laser applying unit that applies the laser beam to a junction of the bone and the implant material to drill a hole in the bone and melt the implant material, a processing-condition setting unit that sets a processing condition for at least one of the bone and the implant material, and a control unit that controls an application of the laser beam based on the processing condition. The method includes burning a bone by applying a heat source to the bone, foamed-layer forming including melting sintered implant material by applying the heat source to the implant material in a gas atmosphere produced by burning the bone, and forming a foamed layer on melted implant material in which foamed air bubbles are confined and coagulated.Type: ApplicationFiled: June 2, 2014Publication date: September 18, 2014Applicants: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY, Mitsubishi Electric CorporationInventors: Masaru KANAOKA, Taira OGITA, Tooru MURAI, Shigeru TADANO, Masahiro TODOH
