Abstract

A needle is described for use in simultaneously taking a bone marrow aspirate and a core biopsy sample without sacrificing the quality of either specimen from the posterior iliac crest. The needle comprises a hollow tube with a front-end portion formed to a reduced diameter. The front end is tapered utilizing circumferentially spaced facets, forming a cutting edge. A tapering transition portion, between the main wider portion of the hollow tube and its reduced-diameter front end portion, is formed with a series of serrations/ flutes that help in cutting the dense cortical bone, facilitating penetration. The distal, narrower portion of the needle has two side holes that communicate with the internally hollowed-out trocar and provide means of bone marrow aspiration.
