The invention set forth includes a set of tools which compact bone tissue as
they develop a bore in the bone tissue and a driving mechanism for providing movement
to the tools. The tools have engaging surfaces which displace bone tissue radially
outward with respect to a central axis of the tool to create high density bone
tissue at the wall defining the bore. The driving mechanism may provide only vibrational
movement to assist in inserting the tool. Alternatively, the driving mechanism
may provide translational movement in the longitudinal direction with respect to
the tool to insert the tool into the bone.
