ABSTRACT:
A biopsy needle which contains a rotating and axially removable inner cannula housed within an outer cannula in the form of a penetrating needle, the configuration allowing for the removal of multiple tissue specimens with a single needle insertion, with a minimized risk of trauma to surrounding tissue, the distal ends of the outer and inner cannulas containing coextensive open channels, the outer and inner cannulas having operative distal piercing ends defined by converging lateral piercing edges interconnected inferiorly by a semiconical transverse base surface, and superiorly by trailing semicircumferential cutting edges, angled with reference to the needle horizontal axis, the inner cannula having an operative 180.degree. rotary motion around the common longitudinal axis of the inner and outer cannulas, said rotary action performing the transverse cutting of tissue entrapped within the open distal chamber of the needle, the procedure being performed without the need for suction or irrigation, in such a manner that the structural integrity of the specimen is uniquely preserved.
