Continuous Catheter Peripheral Anaesthesia - N e e d l e   s t y l e s Insulated Cannulae for introducing the catheter in Continuous Peripheral Anaesthesia available in 3 tip styles: Sprotte, Short Bevel, and Tuohy. The atraumatic Sprotte tip is unique in its ability to be placed at a near perpendicular angle to the nerve, whereas the short bevel and tuohy needles need be placed parallel, as shown at left. The Sprotte tip was developed as an atraumatic cannula for single shot use in the sensitive spinal area, however experience has proved its suitability also for the plexus area. While the tuohy tip is particularly suited to lumbar plexus blockade, cannulae with short bevel tip represent an all purpose option for the full range of peripheral blockade.
