Abstract
This bone marrow extraction tool comprises an outer cannula having an interiorly and exteriorly tapered marrow-receiving distal end, and an inner cannula slidably disposed in the outer cannula and having a distal end formed with diametrically opposed narrow and wide longitudinal slots to define resilient sectors. The wide slot is substantially longer than the narrow slot. The mouth of the inner cannula is adapted when forcibly engaging the interior taper of the outer cannula to diminish in diameter as the sectors are cammed inward and thereby compress marrow disposed in the mouth and squeeze it off from the marrow mass outside the outer cannula.
