Bone marrow biopsy needle |
摘要 |
A needle for use in taking a bone marrow biopsy comprises a hollow tube having a front end portion formed to a reduced diameter by swaging. The front end is tapered by means of a number of circumferentially-spaced facets, forming a cutting edge. A tapering transition portion, between the main portion of the hollow tube and its reduced-diameter front end portion, is formed with a series of flutes which help in the needle cutting through the cortical bone. A spacer is provided for use in pushing the sample rearwardly out of the hollow tube, the spacer having a through-passage through which a trocar needle is passed and serving for accurate alignment of the distal ends of the hollow tube and trocar needle.
