The Apriomed Bonopty Bone Biopsy System 10-1073 is a 15 gauge, 16 cm biopsy set that is used to collect bone tissue samples for diagnosis. It is a coaxial system that features an inner cannula and an outer cannula. The inner cannula houses the stylet and the biopsy needle, while the outer cannula protects the inner cannula and helps to create a stable drilling platform.
