A device (100) and method (1200) for
autogenous bone grafting simultaneously cuts a cross-section of a bone (212), both longitudinally with a longitudinal
cutting member (104), and transversely with a saw (140) during a
bone drilling procedure to obtain a
bone block (214) for repairing and rebuilding diseased bones. The device (100) is hand-controllable to selectively
cut internally to the device (100), so as to
cut captured bone (212) for internal bone harvesting. The device (100) also selectively cuts surrounding bone (212) outside the device (100) for external bone harvesting. The saw (140) is biased to stow in a wall space (120) when not in use, and rotate along a perpendicular plane (202) inwardly or outwardly for internal or external
cutting of the bone (212), respectively. The saw (140) rotatably extends inwardly to support and carry the
bone block (214) after a longitudinal section has been
cut. The saw (140) rotatably extends outwardly from the device (100) to release the
bone block (214) after the
bone grafting procedure.
