Abstract
A biopsy needle for collecting a tissue specimen includes an outer cannula that is at least partially received within a handle housing and an inner tube received within the outer cannula and configured to receive a stylet. A snare coil is attached between the inner tube and the outer cannula and a movable base is disposed within the handle housing. The outer cannula is fixedly coupled to the base and the movable base is axially movable within the handle housing. An inner driven structure that is coupled to the inner tube is configured to travel axially across an upper surface of the movable base. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.
