摘要:
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%.
摘要:
A method of integrating bone and implant material includes drilling a hole in either one of the bone and the implant material through to a junction of the bone and the implant material by applying a laser beam to either one of the bone and the implant material and integrating the bone and the implant material by applying a laser beam to the junction through the hole drilled at the drilling.

摘要:
An MRE excitation apparatus (100) comprises an excitation device (110) that generates vibration, and a transmitter (120) that is made using a non-magnetic material and that, with one end-section being fastened to the excitation device (110) and the other end-section being connected with a living body (300), and that extends in direction that vibration is transmitted from the excitation device (110) and transmits longitudinal vibration from the excitation device (110) to the living body (300). The frequency of the vibration is 125 Hz or greater, the amplitude of the vibration is 0.2 mm or greater, and the primary natural frequency of the longitudinal vibration of the transmitter (120) is further on the higher side than the frequency band of the vibration from the excitation device (110).
