Bone marrow biopsy, aspiration and transplant needles

摘要

Novel bone-marrow biopsy, aspiration and transplant needles are described having several unique features. One unique feature is an offset handle which allows a user to use their index finger to guide a needle into a patient. Another unique feature is a cannula which has multiple cutting teeth that can be used to cut bone when the cannula is axially rotated. Yet another unique feature is a stylet with a highly effective cutting tip.
