Abstract: A device(100) and method(4100) for autologous bone graft harvesting simultaneously cuts a cross-section of a bone(900) longitudinally with a longitudinal drill assembly(102), and transversely with a saw assembly(126) during a bone(900) drilling to obtain a bone block for repairing and rebuilding diseased bones. The longitudinal drill assembly(102) and the saw assembly(126) simultaneously cut a cross-section of a bone(900). The device(100) is hand-controllable, drill motor powered, and spring-tensioned to selectively cut internally to the captured bone for internal bone harvesting. The longitudinal drill assembly(102) includes a drill shaft(114) extending perpendicular from a drill plate(112), having a flat surface(204) with a depth gauge(116). A module assembly(118) includes a module plate(120) disposed above the drill plate(112). Pins(302a,302b) extend from the upper face(308a) of the module plate(120) to engage ends of slots(400a,400b) to restrict over-rotation of saw plate(128).

Abstract: 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.
