Abstract

Apparatus for directing the tip of a scoping instrument having an elongated image transmitting optical system. The elongated optical system is slidably received within the tubular member of a directing cannula mechanism having a bending section at its distal end. The optical system is then held against longitudinal movement relative to the cannula mechanism at a location distant from the distal end. The cannula mechanism can be rotated on its axis for moving the tip of the optical system through 360.degree. of azimuth. A control mechanism is operable from a proximal end of the directing cannula mechanism and includes a single cable which extends through the tubular member to an annular member at the extremity of the distal end. When the desired azimuthal position of the cannula mechanism is achieved the cable is tensioned, enabling the annular member, and with it the tip of the optical system, to be deflected through an arc of 90.degree., or more.
