Abstract

The present specification describes a medical endoscope, such as but not limited to a gastroscope, a colonoscope or a bronchoscope. In particular, the present specification describes an endoscope having a supply cable that includes a coupling element dividing the supply cable into a first section and a second section capable of rotating relative to each other, wherein the endoscope system further includes a control unit or endoscope handle and a main connector or supply plug connected to opposite ends of the supply cable.

Claims

1. An endoscope system comprising an endoscope, a main controller, and a supply cable adapted to connect the endoscope to the main controller, the supply cable comprising:

a first section, wherein the first section has a first end and a second end, the second end configured to attach to the main controller;

a second section, wherein the second section has a first end configured to attach to the endoscope, and a second end;

a coupling element for connecting the first end of the first section with the second end of the second section, wherein the coupling element is configured to enable the first section to rotate relative to the second section and wherein the coupling element further comprises;

a first coupling component attached to the first end of the first section;

a second coupling component attached to the second end of the second section;

a groove extending around at least a portion of an outer periphery of one of the first coupling component and the second coupling component, the groove including at least one planar radially-extending surface;

a carriage configured to be movable in said groove, wherein the carriage is coupled to the other of the first coupling component and the second coupling component, the carriage includes at least one planar surface facing the at least one planar radially-extending surface of the groove; and

a fastening mechanism fastened to the carriage.

2. The endoscope system as claimed in claim 1 wherein the first and the second coupling components are cylindrical in shape.

3. The endoscope system as claimed in claim 1 wherein a diameter of a portion of the second coupling component is greater than a diameter of a portion of the first coupling component, the first and the second coupling components being coupled by inserting said portion of the first coupling component into said portion of the second coupling component.

4. The endoscope system as claimed in claim 1 wherein the fastening mechanism is inserted radially into at least one of the first and second coupling components through one or more openings in a wall of at least one of the first and second sections of the supply cable and fastened to one or more threaded holes in the carriage.

5. The endoscope system as claimed in claim 1 further comprising an abutment that limits an angle of rotation of the first and the second sections of the supply cable relative to each other by abutting the carriage.

6. The endoscope system as claimed in claim 1 wherein the coupling element further comprises a first o-ring seal and a second o-ring seal placed in alignment with a gap separating the first and the second o-ring seals, the first and the second o-ring seals enabling the first and the second sections of the supply cable to be rotatably connected while preventing contaminants from entering the endoscope.

7. The endoscope system as claimed in claim 1 wherein the coupling element and at least a portion of the first and second sections of the supply cable are covered with a cover for preventing contaminants from entering the endoscope.

8. An endoscope system comprising an endoscope, a main controller, and a supply cable adapted to connect the endoscope to the main controller, the supply cable comprising:

a first section, wherein the first section has a first end and a second end, the second end configured to attach to the main controller;

a second section, wherein the second section has a first end configured to attach to the endoscope, and a second end;

a coupling element for connecting the first end of the first section with the second end of the second section, wherein the coupling element is configured to enable the first section to rotate relative to the second section, and wherein the coupling element further comprises;

a first coupling component attached to the first end of the first section;

a second coupling component attached to the second end of the second section;

a recess extending around at least a portion of an outer periphery of one of the first coupling component and the second coupling component;

a slide member configured to be slideably received in said recess, wherein the slide member is coupled to the other of the first coupling component and the second coupling component; and

a fastening element configured to couple the other of the first coupling component and the second coupling component to the slide member.

9. An endoscope system as in claim 8, wherein the slide member includes at least one threaded hole.

10. An endoscope system as in claim 8, wherein the slide member includes at least one radially-extending through-hole.

11. An endoscope system as in claim 8, wherein the fastening element is a screw.

12. An endoscope system as in claim 8, further comprising:

a first cover attached to the first end of the first section of the supply cable; and

a second cover attached to the second end of the second section of the supply cable;

wherein the second cover is configured to receive the first cover.

13. An endoscope system as in claim 8, wherein the carriage includes a curved radially-outward-facing side surface.

14. An endoscope system comprising an endoscope, a main controller, and a supply cable adapted to connect the endoscope to the main controller, the supply cable comprising:

a first section, wherein the first section has a first end and a second end, the second end configured to attach to the main controller;

a second section, wherein the second section has a first end configured to attach to the endoscope, and a second end;

a coupling element for connecting the first end of the first section with the second end of the second section, wherein the coupling element is configured to enable the first section to rotate relative to the second section and wherein the coupling element further comprises;

a first coupling component attached to the first end of the first section;

a second coupling component attached to the second end of the second section;

a groove extending around at least a portion of an outer periphery of one of the first coupling component and the second coupling component, the groove including at least one axially-facing sidewall; and

a slide member configured to be slidable in said groove, wherein the slide member is coupled to the other of the first coupling component and the second coupling component, and the slide member includes at least one axially-facing sidewall, and wherein the at least one axially-facing sidewall of the slide member slidably contacts the at least one axially-facing sidewall of the groove;

at least one fastening element configured to couple the other of the first coupling component and the second coupling component to the slide member.

15. An endoscope system as in claim 14, wherein the carriage includes a curved radially-outward-facing side surface.

16. An endoscope system as in claim 14, wherein the axially-facing sidewall of the slide member is planar.

17. An endoscope system as in claim 14, further comprising:

a first cover attached to the first end of the first section of the supply cable; and

a second cover attached to the second end of the second section of the supply cable;

wherein the second cover is configured to receive the first cover.

18. An endoscope system as in claim 14, wherein the groove includes two axially-facing sidewalls;
