Abstract: The device includes a shaft having a plurality of interengaging shaft members. A tension member extends through the shaft and is positional between two positions. When the tension member is in the first position thereof, the shaft members are capable of movement relative to one another allowing the shaft to be manipulable between a continuous range of positions. When the tension member is biased to the second position thereof, the shaft members are non-movably held together forming a rigid shaft of desired shape. An articulation member extends through the shaft and is connected to a live attachment which is retained on a distal end of the shaft. By manipulation of the articulation member at a proximal end of the shaft the live attachment is manipulated.
