Device for removing cancellous bone

摘要

A device (10) for removing cancellous bone during machining of a long bone canal includes a brush mechanism for scraping cancellous bone from cortical bone while deflecting off the cortical bone and a center post (14) operatively connected to the brush mechanism (12) for centering the brush mechanism (12) relative to the long bone canal. An adapter mechanism (16) is connected to the center post (14) for connecting the center post (14) to a motion actuator to move the brush mechanism (12) relative to the long bone canal and scrape off cancellous bone therefrom.
