Abstract

A probe controller is integral with a gripper for the probe'"'"'s insertion tube. The gripper is easily operated with one hand, permitting a user to hold, release, and insert the insertion tube with the same hand that operates the controls on the controller, thus freeing the user'"'"'s other hand to feed the insertion tube into the opening, perform other operations, or optionally to operate the controls.

Claims

1. A tube gripper for an endoscopic apparatus, comprising:

a hand-held control unit, said hand-held control unit including at least one user-actuable control feature for controlling at least one function of said probe;

a tube channel running lengthwise through the interior of said hand-held control unit and sized for receiving an insertion tube of said endoscopic apparatus; and

gripping means disposed within said hand-held control unit for frictionally connecting said tube channel to said insertion tube.

2. A tube gripper according to claim 1, wherein said one user-actuable control feature includes at least one of a joystick and a trackball disposed on the exterior of said hand-held control unit.

3. A tube gripper according to claim 2, further comprising means for connecting said at least one user-actuable control feature to a probe base unit.

4. A tube gripper according to claim 3, wherein said means for connecting includes a cable.

5. A tube gripper according to claim 3, wherein said means for connecting includes means for wireless data transfer between said at least one user-actuable control feature and said base unit.

6. A tube gripper according to claim 1, wherein said gripping means comprises an opening in a middle portion of said control unit such that said tube channel is exposed such that at least one finger of a user frictionally connects said tube channel to said insertion tube.

7. A tube gripper according to claim 1, wherein said gripping means comprises:

a mechanical gripping mechanism inside said control unit; and

one of a finger and thumb trigger mechanically linked to said gripping mechanism such that pressing said one of said finger and thumb trigger frictionally connects said tube channel to said insertion tube.

8. A tube gripper according to claim 7, wherein said mechanical gripping mechanism is disposed in a front portion of said control unit.

9. A tube gripper according to claim 7, wherein said mechanical gripping mechanism is disposed in a middle portion of said control unit.

10. A tube gripper according to claim 1, wherein said gripping means comprises:

a mechanical gripping mechanism inside said control unit; and

one of a finger and thumb trigger mechanically linked to said gripping mechanism such that releasing said one of a finger and thumb trigger frictionally connects said tube channel to said insertion tube.

11. A tube gripper according to claim 10, wherein said mechanical gripping mechanism is disposed in a front portion of said control unit.

12. A tube gripper according to claim 10, wherein said mechanical gripping mechanism is disposed in a middle portion of said control unit.

13. A tube gripper according to claim 1, wherein a middle portion of said control unit is shaped to conform to a hand grip of a user.

14. A tube gripper according to claim 1, wherein said gripping means includes a material affixed to an inside of said tube channel which has a lower sliding coefficient of friction than a static coefficient of friction.

15. A tube gripper according to claim 1, further comprising a video display detachably mounted on said hand-held control unit.

16. A tube gripper according to claim 1, wherein said tube channel receives said insertion tube only through an end of said tube channel.

17. A rube gripper according to claim 1, wherein said tube channel receives said insertion tube through a lengthwise slit in said tube channel.

18. A tube gripper according to claim 1, further comprising a movable panel which permits said insertion tube to be placed in said tube channel at any point along said insertion tube.

19. A tube gripper according to claim 1, further comprising a displaceable barrier along an underside of said tube channel such that said insertion tube may be forced past a displaceable barrier into said tube channel at any point along said insertion tube.

20. A tube gripper according to claim 1, further comprising a video display connector on said hand-held control unit.

21. A tube gripper according to claim 1, further comprising a microphone disposed within said hand-held control unit.

22. A tube gripper according to claim 1, further comprising a loudspeaker disposed within said hand-held control unit.

23. A tube gripper according to claim 1, wherein said user-actuable control feature includes at least one of a key switch and a button disposed on the exterior of said hand-held control unit.
