1. A medical device, comprising:
a handle with a central axis;
a flexible tubing which extends from the handle and has a proximal end fixed to the handle;
a flexible tip attached to a distal end of the flexible tubing and adapted for bending within multiple bending planes;
a tip actuator assembly for adjusting a bending plane of said multiple bending planes of the tip relative to the distal end of the flexible tubing and for adjusting a degree of bending of the tip in the bending plane; and
a user operable control, supported on the handle, and moveable in a first, rotational direction relative to the handle and to the tip actuator assembly around an axis of rotation, for causing the tip actuator assembly to adjust the bending plane of the tip substantially without rotating the flexible tubing,
wherein the user operable control further is slidable around the handle and the tip actuator assembly in a second, substantially linear direction towards and away from the proximal end of the flexible tubing, for causing the tip actuator assembly to adjust the degree of bending of the tip in the bending plane without adjusting the bending plane,
wherein the tip actuator assembly comprises:
a tilting plate which is tiltable relative to the central axis for adjusting the bending plane of the tip relative to the distal end of the flexible tubing and the degree of bending in said bending plane, the tilting plate being axially moveable along the central axis;
a blocking element that is fixed with respect to the central axis and configured to prevent rotation of the tilting plate around the central axis; and
multiple steering cables which are partially arranged within the flexible tubing and are connected at a first end to the tip and connected at a second end to the tilting plate.
