Abstract

An endoscope (22) with an elongated shaft (23) and a light post (58). One or more sensed elements are fitted to the light post. The sensed elements may be magnets (432). The sensed elements may be mounted in an adapter (126) that is removably attached to the light post.

Claims

1. An endoscope, said endoscope including:

an elongated shaft, said shaft having a distal end and a proximal end spaced from the distal end;

a light post that extends outwardly from said shaft, said light post being adapted to receive a fiber optic cable; and

at least one sensed element mounted to said light post, said at least one sensed element being a magnet disposed in a housing attached to said light post.

2. The endoscope of claim 1, wherein said magnet is fully enclosed in said housing.

3. The endoscope of claim 1, wherein said housing is removably attachable from said light post and said housing is adapted to receive the fiber optic cable.

4. The endoscope of claim 3, wherein said magnet is fully enclosed in said housing.

5. The endoscope of claim 1, wherein said housing is an adapter that is configured to be removably attached to said light post and said adapter is configured to receive the fiber optic cable.

22. The endoscope of claim 1, further including an alignment member that extends forward of said magnet that is positioned to engage a complementary recess defined by the fiber optic cable.

6. An endoscope, said endoscope including:

an elongated shaft, said shaft having a distal end and a proximal end spaced from the distal end;

a light post that extends outwardly from said shaft, said light post being adapted to receive a fiber optic cable; and

at least one magnet mounted to said light post, wherein said at least one magnet is fully enclosed within a body.

7. The endoscope of claim 6, further including an adapter that is releasably attached to said light post, wherein:

said adapter is said body in which said at least one magnet is mounted;

said adapter has a first coupling member for releasably securing said adapter to said light post; and

said adapter has second coupling member for releasably securing the fiber optic cable to said adapter.

8. The endoscope of claim 6, further including an alignment member that extends forward beyond a face of said light post against which the fiber optic cable is positioned.

9. An adapter for coupling a fiber optic cable to an endoscope, said adapter comprising:

a body, said body having first and second opposed ends and a through bore that extends between the ends of said body;

a first coupling member fitted to said body adjacent the first end, said first coupling member configured to releasably secure said body to an endoscope;

a second coupling member fitted to said body adjacent the second end, said second coupling member configured to releasably secure a fiber optic cable to the second end of said body; and

at least one sensed member fitted to the second end of said body.

10. The adapter of claim 9, wherein said at least one sensed member has an exposed surface and said at least one sensed member is mounted to said body so that, when the fiber optic cable is secured to said body, said at least one sensed member exposed surface is in contact with the fiber optic cable.

11. The adapter of claim 10, wherein:

said at least sensed member is moveably fitted to said body; and

a biasing member is disposed between said body and said at least one sensed element, said biasing member positioned to impose a biasing force on said at least one sensed member.

12. The adapter of claim 9, wherein:

said body has a surface adjacent which the fiber optic cable is positioned; and

an alignment member is mounted to said body, said alignment member being positioned to extend beyond the surface of said body against which the fiber optic cable is positioned.

13. The adapter of claim 9, wherein said at least one sensed member is fully enclosed in said body.

14. The adapter of claim 13, wherein said at least one sensed member is a magnet.

15. The adapter of claim 9, wherein said first coupling member is threading formed on an interior surface of said body.

16. The adapter of claim 9, wherein said second coupling member is a snap ring that is fitted to said body.

23. The adaptor of claim 10, wherein said sensed element is an electrically conductive component and the exposed surface of said sensed member establishes an electrical connection with a complementary electrical contact integral with the fiber optic cable.

24. The adaptor of claim 14, wherein said alignment member is a pin.

17. An adapter for coupling a fiber optic cable to an endoscope, said adapter comprising:

a body, said body having first and second opposed ends and a through bore that extends between the ends of said body;

a first coupling member fitted to said body adjacent the first end, said first coupling member configured to releasably secure said body to an endoscope;

a second coupling member fitted to said body adjacent the second end, said second coupling member configured to releasably secure a fiber optic cable to the second end of said body; and

at least one magnet is disposed in said body adjacent the second end of said body.

18. The adapter of claim 17, wherein:

said body is formed with an opening adjacent the second end of said body;

said at least one magnet is fitted in the opening; and

a member covers said magnet and the opening.

19. The adapter of claim 17 further including an alignment member that is mounted to said body, said alignment member being positioned and dimensioned to extend beyond the second end of said body.

20. The adapter of claim 17, wherein said first coupling member is threading formed on an interior surface of said body.

21. The adapter of claim 17, wherein said second coupling member is a snap ring that is fitted to said body.

25. The adaptor of claim 19, wherein said alignment member is a pin.
