Abstract
A biopsy needle instrument has selectable locking means to permit or prevent the projection of a cannula and a stylet and separate loading members allowing the cannula and stylet to be loaded separately and yet fired sequentially using a single button. Another embodiment of the invention permits the independent firing of the stylet and the cannula.
