Abstract
A bone biopsy needle assembly includes an elongated tubular cannula having an axially extending lumen therethrough. A guide is provided to facilitate insertion of a probe into the cannula for sample removal. The guide has a molded shape with an elongated dimension having first and second ends. A cylindrical opening extends through the length of the elongated dimension and has a diameter substantially equal to that of the interior lumen of the cannula. A flared outward enlargement of the cylindrical opening at each of the first and second ends provides for easy alignment of one of the ends with the distal end of the cannula and the other end forms a guide for insertion of a probe into the distal end of the cannula for removal of the biopsy specimen.
