Abstract
A bone marrow biopsy needle includes an outer tube having a lumen extending therethrough which narrows at the distal end of the outer tube. An inner tube is slidable through the lumen of the outer tube and includes a pair of pincers at its distal end. As the inner tube is slid through the lumen of the outer tube, the pincers will encounter the narrowed portion of the lumen and as the pincers extend beyond an opening at the distal end of the outer tube, the pincers close upon themselves, and in this manner the pincers can grasp a biopsy core from bone marrow of a patient. The pincers may have sharpened edges and/or have their edges bent radially inwardly so as to enhance the cutting of the biopsy core from the bone marrow.
