A system for detecting and removing foreign object debris from an enclosed region is capable of insertion through a small-sized opening. A source of light is optically transmitted through a first window in the outer peripheral surface of an elongated borescope adjacent its distal end to illuminate a debris containing region. An image of the region is transmitted through a second window in the distal end of the borescope to a remote television monitor. A vacuum conduit extends to a flexible tip end which is proximate to the distal end of the borescope and is connected to a source of vacuum to create a suction at the tip end. An elongated guide sleeve serves to slidably receive the vacuum conduit. The tip end of the vacuum conduit is movable relative to the guide sleeve between a retracted position substantially coincident with the first end of the guide sleeve and an extended position whereat the tip end of the vacuum conduit is distant from the first end. The first end of the guide sleeve can be articulated from a neutral position aligned with its longitudinal axis and an operating transverse position such that the flexible tip end of the vacuum conduit is similarly turned. Additionally, the guide sleeve is rotatable about its longitudinal axis to thereby position the tip end of the vacuum conduit proximate to the debris when the tip end is in the operating position for withdrawal of the debris for disposal.

A system capable of insertion through a small-sized opening into an enclosed region for detecting and removing foreign object debris from the enclosed region comprising: an elongated tubular borescope having an outer peripheral surface and extending between proximal and distal ends, said borescope including: first and second windows in said outer peripheral surface adjacent said distal end; a source of light remote from said distal end; first optical transmission means within said borescope for transmitting light from said light source to and through said first window to illuminate a debris containing region to be inspected externally of said distal end of said borescope; television means for presenting an image to a viewer; second optical transmission means within said borescope for transmitting an image from the debris containing region to said television means; a vacuum conduit extending between a near end and a tip end proximate to said distal end of said borescope and being flexible at least adjacent said tip end, said vacuum conduit being operably connected to a source of vacuum to create a suction at said tip end; and an elongated guide sleeve having a longitudinal axis for slidably receiving said vacuum conduit therethrough, said guide sleeve extending between first and second ends, said near end of said vacuum conduit being external of said guide sleeve and extending beyond said second end, said tip end of said vacuum conduit being movable relative to said guide sleeve between a retracted position whereat said tip end of said vacuum conduit is substantially coincident with said first end of said guide sleeve and an extended position whereat said tip end of said vacuum conduit is distant from said first end, said first end of said guide sleeve being capable of articulation from a neutral position aligned with said longitudinal axis and an operating position extending transverse of said longitudinal axis whereby said tip end of said vacuum conduit is similarly turned to an operating position extending transverse of said longitudinal axis; said vacuum conduit being rotatable relative to said guide sleeve about said longitudinal axis to position said tip end thereof proximate to the debris at the debris containing region when said tip end is in the operating position to thereby withdraw the debris for disposal.
