One Medical Devices control handle or conduit include deviator and hereafter at least one: a disc actuator, a lever actuator and a ring actuator, are used to independent from each other drive an additional bracing wire in the operation of Medical Devices or the multiclass feature of conduit. Since disc actuator is installed in a part of pulley arm, but it is rotatably independently of pulley arm, disc actuator has a common rotation axis of deviator. What pulley arm of the lever actuator with one from the pulley arm isolated rotary shaft and with its rotary shaft can be distal end is oriented the vertical of the substantially rotary shaft of pulley arm. It is installed except control handle relative to control handle and rotatable ring is to drive another bracing wire of another feature for manipulating conduit. Each disk, lever and ring actuator have a design, allow existing control handle and conduit is to be readily modified to include these actuators.
