Abstract
A biopsy needle set 10 comprises an outer cannula 1 and an inner cannula 2. The outer cannula 1 includes an outer opening 14 and the inner cannula 2 includes an inner opening 12. The inner cannula 2 is rotatable relative to the outer cannula 1 such that the needle set 10 has an opened position wherein the inner opening 12 is located adjacent to the outer opening 14, and a closed position wherein the outer cannula 1 covers the inner opening 12. The needle set, in a closed position, can be inserted into a body in order to collect a tissue sample. Once properly inserted, the needle set can be moved to an opened position and then either selectively further inserted and closed to collect the tissue sample or closed to collect the tissue sample.
