Abstract

A remote viewing device including a hand-holdable control unit. The control unit supports a display device and a drive assembly. The drive assembly is removably attached to the control unit and provides mechanical power to an insertion tube. A distal end of the insertion tube includes an inspection head for insertion into a structure for imaging the interior of the structure. The insertion tube is removably attached to the drive assembly by a connector assembly, where the connector assembly is operable, when attached, to convey mechanical power from the drive assembly for moving the articulated tip in response to a user input at the control unit, and to convey images from the inspection head to the display device.

Claims

1. A remote viewing device comprising:

a hand-holdable control unit;

a display device mounted to said control unit;

a drive assembly removably attached to said control unit for providing mechanical power;

an insertion tube comprising a proximal end and an articulated tip at a distal end;

an inspection head associated with said articulated tip, said inspection head configured for imaging the interior of an object;

and a connector assembly removably interconnecting said control unit and said proximal end of said insertion tube, said connector assembly operable, when connected, to convey the mechanical power from said drive assembly for moving said articulated tip in response to a user input at said control unit, and to convey images from said inspection head to said display device.

2. The remote viewing device of claim 1, wherein said connector assembly comprises a first connector half supported on said drive assembly and a second connector half supported on said insertion tube for detachable connection to said first connector half, said first connector half being removable from said control unit with said drive assembly.

3. The remote viewing device of claim 1, wherein said insertion tube comprises a plurality of cables for conveying the mechanical power from the proximal end to the articulated tip, and said drive assembly includes cable pull racks for actuating said cables.

4. The remote viewing device of claim 3, including a coupling on the end of each said cable, and each said coupling being detachably engaged on the end of a respective cable pull rack to define detachable connections between said cables and said cable pull racks.

5. The remote viewing device of claim 3, wherein said drive assembly comprises a pair of motors, each said motor actuating a respective pair of said cable pull racks in longitudinal movement within said drive assembly.

6. The remote viewing device of claim 5, wherein said drive assembly includes a mount element for removable attachment to a side of said control unit.

7. The remote viewing device of claim 6, said drive assembly comprises a housing enclosing said cable pull racks and said housing is supported on said mount element for said removable attachment to said control unit.

8. The remote viewing device of claim 1, wherein said inspection head comprises a camera and a light source.

9. The remote viewing device of claim 8, wherein said camera and said light source are removably attached to said inspection head.

10. The remote viewing device of claim 8, wherein said connector assembly is further operable, when connected, to convey electrical power to said camera and said light source.

11. The remote viewing device of claim 1, including a memory device removably attached to said control unit, said memory device including operating system software for use by a processor in said control unit to control an image processing operation.

12. The remote viewing device of claim 11, wherein said memory device comprises a memory card.

13. The remote viewing device of claim 1, including a plurality of insertion tubes interchangeably attachable to said control unit, each insertion tube having a different cross-sectional dimension.

14. A remote viewing device comprising:

a hand-holdable control unit;

a display device mounted to said control unit;

a drive assembly for providing mechanical power;

an insertion tube comprising a proximal end and an articulated tip at a distal end;

an inspection head associated with said articulated tip, said inspection head configured for imaging the interior of an object;

and a connector assembly removably interconnecting said control unit and said proximal end of said insertion tube, said connector assembly operable, when connected, to convey images from said inspection head to said display device.

15. The remote viewing device of claim 14, wherein said insertion tube comprises a plurality of cables for conveying the mechanical power from the proximal end to the articulated tip, and said drive assembly comprises a motor operably connected to said cables.

16. The remote viewing device of claim 15, wherein said connector assembly is further operable, when connected, to convey the mechanical power from said drive assembly to said cables for moving said articulated tip in response to a user input at said control unit.

17. The remote viewing device of claim 14, wherein said inspection head comprises a camera and a light source.

18. The remote viewing device of claim 17, wherein said camera and said light source are removably attached to said inspection head.

19. The remote viewing device of claim 17, wherein said connector assembly is further operable, when connected, to convey electrical power to said camera and said light source.

20. The remote viewing device of claim 14, including a plurality of insertion tubes interchangeably attachable to said control unit, each insertion tube having a different cross-sectional dimension.
