A medical device includes a handle； flexible tubing extending from the handle and having a proximal end fixed to the handle； flexible tip attached to the distal end of the flexible tubing； a tip actuator assembly adjusting the bending plane of the tip relative to the distal end and adjusting the degree of bending of the tip in the bending plane； user operable controls on the handle and moveable in a first, rotational direction relative to the handle and to a tip actuator assembly around an axis causing the tip actuator assembly to adjust the bending plane of the tip substantially and moveable relative to the handle and the tip actuator assembly along a second, substantially linear direction towards and away from the proximal end of the flexible tubing, causing the tip actuator assembly to adjust bending of the tip in the bending plane without adjusting the bending plane.
