Abstract
This bone marrow extraction tool comprises an outer cannula having an interiorly tapered marrow-receiving distal end, and an inner cannula slideably disposed in the outer cannula and having a distal end formed with longitudinal slots to define resilient sectors. The mouth of the inner cannula adapted when forcibly engaging the interior taper of the outer cannula to diminish in diameter as the sectors flex inward and thereby compress marrow disposed in the mouth and squeeze it off from the marrow mass outside the outer cannula.
