ABSTRACT:
A biopsy needle for excising tissue specimens for microscopic examination including a tubular sheath having an axially extending open-side and a tapered point. The open side is provided with opposed grooves which guide a slidable stylet having a tapered end with sharp cutting edges. The tapered end of the stylet is either preformed to curve to the tapered point of the sheath or guided in internal grooves of the sheath to the insertion point of the sheath to occlude the tapered end of the sheath and incise and enclose a tissue specimen.
