摘要： The bone marrow harvesting drill of the invention includes an inner needle having a cutting edge at the tip thereof; a tubular mantle that receives the inner needle thereinto so that the inner needle and the tubular mantle are detachably attached; and a lock mechanism that prevents the axial rotation of the tubular mantle and the inner needle relative to each other; the inner needle having a groove formed at the tip thereof projecting from the tubular mantle for discharging bone scraps produced by the cutting edge at the tip of the inner needle; and the tubular mantle having a cutting edge formed at the tip edge thereof and a helical groove extending from the tip edge to at least part of the peripheral surface of the tubular mantle so as to be flush with the groove of the inner needle.
