CANCELLOUS BONE GRAFT SUBSTITUTE AND ITS PROCESS

摘要

PURPOSE: cancellous bone transplantation object material and manufacturing method manufacture bone graft material provide high-quality characteristic substance include elastic stiffness etc. and the osteoacusis element that discharged is effectively protected the element later by keeping. ;CONSTITUTION: the manufacturing method of cancellous bone graft material includes the following steps: step (S110), degreasing, is dehydrated and sterilized bone tissue and ethanol solution; Step (S120), sterilizing and oxidized bone tissue and hydrogen peroxide; Step (S130), after processing bone particle is cubic subtly cutting,It aoxidizes and has sterilized on bone tissue; Step (S140), particles of the decalcificating through treated bone cubic shaped, uses the hydrochloric acid; Step (S150) cleans decalcificated skeletal grains and ethanol solution; Step (S160), bone particle and phosphate buffer after counteracting; Step (S170), dipping bone particle enter RSC solution; Step (S180), the bone slag lyophilizate particle. ;The 2010 of copyright KIPO submissions
