Abstract
In one embodiment, a biopsy needle that is particularly suited for shearing and collecting soft tissue specimens is provided and is formed of an inner tube with a snare at a distal end thereof, an outer cannula, a stylet and a handle assembly. The handle assembly includes a spring loaded mechanism that permits the user to selectively actuate the biopsy needle so that the outer cannula and the inner tube are rapidly advanced beyond the stylet to provide a shearing action of the soft tissue specimen.
