A movement transfer mechanism for a surgical scoping device, wherein a rotational proximal input force is transformed into a longitudinal force that is conveyed down the length of an instrument channel of the scoping device, where it is transformed again into an operational movement of a distal instrument. The operational movement can be rotational movement, but may be any movement that changes the orientation or configuration of the distal instrument. By conveying a linear force along the instrument channel rather than a twisting force, the problems of slipping and discontinuous operation of the distal instrument due to friction between the instrument and the instrument channel can be reduced or eliminated.
