High-level building a bridge ultra high molecular weight polyethylene (UHMWPE) from at production manner and medical application in plant part null high-level cross-linked polyethylene of in

摘要

The present invention relates to a process for the preparation of the implant parts that have been formed by highly cross-linked polyethylene. In the present method, to generate free radicals within a blank by irradiation with ionizing radiation in the ultra-high molecular weight polyethylene blank. In order to optimize the degree of crosslinking of the highly crosslinked polyethylene, to scavenge free radicals, and performs post-processing ultrasonic and microwave radiation and / or blank. In the post, almost complete recombination is achieved free radicals that do not recombine is excited. After treatment, I molded by machining the blank. The present invention further relates to the implant component medical prepared by the above procedure.
