Title:
高度架橋超高分子量ポリエチレン(UHMWPE)から形成されたインプラント部品の製造方法及び医療用インプラント部品
Document Type and Number:
Japanese Patent JP2004526010
Kind Code:
A
Abstract:
The invention relates to a method of manufacturing implant parts made of highly cross-linked polyethylene, wherein a blank made of ultra-high-molecular-weight polyethylene is irradiated with ionizing radiation in order to produce radicals in the blank. To optimize the cross-linkage of the highly cross-linked polyethylene and to eliminate free radicals, the blank is subsequently treated by means of microwave radiation and/or ultrasound in such a way that free radicals, which have not recombined, are excited so as to ensure substantially complete recombination of the free radicals. The shape of the treated blank can then be adjusted by means of machining. The invention further relates to implant parts for application in human medicine that have been manufactured as described above.
