Abstract

The disclosed technology is directed to a cover removal jig for an endoscope that removes a tip cover applied to a distal end of an insertion section of an endoscope. The cover removal jig includes an enclosing portion and a cylinder connected to the enclosing portion. The enclosing portion is to be applied to the tip cover to surround its circumference, and has a portion engageable with the tip cover. The cylinder is made from elastic material and capable to come into close contact with a part of an outer surface of the insertion section.

Claims (35)

1. A cover removal jig for an endoscope used to remove a first tip cover attached to a distal end of an insertion portion of the endoscope, the cover removal jig comprising:

a first enclosing portion configured to encapsulate the first tip cover and having a portion being engageable with the first tip cover; and

a cylinder being flexible and configured to connect to the first enclosing portion and capable of coming into close contact with a part of an outer surface of the insertion portion.

2. The cover removal jig for an endoscope of claim 1 , wherein the cylinder extends from the first enclosing portion in a direction along a longitudinal direction of the insertion portion.

3. The cover removal jig for an endoscope of claim 1 , wherein the cylinder includes a first anti-slip portion being formed on an inner circumferential wall thereof.

4. The cover removal jig for an endoscope of claim 3 , wherein the first anti-slip portion includes a plurality of concavities and convexities formed on the inner circumferential wall of the cylinder.

5. The cover removal jig for an endoscope of claim 1 , wherein the cylinder includes a second anti-slip portion on an outer circumferential wall thereof.

6. The cover removal jig for an endoscope of claim 5 , wherein the second anti-slip portion includes a plurality of grooves formed on the outer circumferential wall of the cylinder.

7. The cover removal jig for an endoscope of claim 1 , further comprising:

a grip handle configured to be attached to the first enclosing portion on a side thereof opposite to a side thereof where the cylinder is connected.

8. The cover removal jig for an endoscope of claim 7 , wherein the grip handle includes a third anti-slip portion on an outer circumferential wall thereof.

9. The cover removal jig for an endoscope of claim 7 , wherein the grip handle has an inner diameter greater than an outer diameter of the insertion portion.

10. The cover removal jig for an endoscope of claim 7 , further comprising:

a second enclosing portion configured to be attached to the grip handle on a side thereof opposite from the first enclosing portion and wherein the second enclosing portion is configured to encapsulate a second tip cover having a diameter different from that of the first tip cover, and having a portion being engageable with the second tip cover.

11. The cover removal jig for an endoscope of claim 1 , wherein the cylinder includes a first marker used to indicate a position where a force should be applied by an operator.

12. The cover removal jig for an endoscope of claim 1 , further comprising: a second marker is formed on the cylinder to indicate a direction in which the cylinder should be rotated relative to the first enclosing portion.

13. The cover removal jig for an endoscope of claim 1 , further comprising: a second marker is formed on the first enclosing portion to indicate a direction in which the first enclosing portion is rotated relative to the cylinder.

14. The cover removal jig for an endoscope of claim 1 , wherein the first enclosing portion and the cylinder are rotatable about a common axis that extends along a central axis of the insertion portion.

15. The cover removal jig for an endoscope of claim 1 , wherein the cylinder includes a notched portion at a position deviated from a portion where the cylinder is gripped by an operator.

16. The cover removal jig for an endoscope of claim 1 , wherein the cylinder is detachably connected to the first enclosing portion.

17. The cover removal jig for an endoscope of claim 1 , the cylinder further comprising a reduced diameter portion, wherein a diameter of the reduced diameter portion is smaller than a diameter of another portion of the cylinder.

18. The cover removal jig for an endoscope of claim 1 , wherein the cylinder includes two semi-cylindrically shaped portions.

19. An endoscope system comprising: the cover removal jig of claim 1 ; and an endoscope having the insertion portion to be inserted into a lumen and the first tip cover is attached to the distal end of the insertion portion.

20. A cover removal jig for an endoscope comprising:

an enclosing portion; and

a cylinder being attached to the enclosing portion to conceal the enclosing portion, wherein:

the cover removal jig configured to engage with the endoscope to remove a portion of endoscope after being used in a body; and

the cylinder is flexible.

21. The cover removal jig for an endoscope of claim 20 , wherein the cylinder is elastically attached to the enclosing portion, and wherein the cylinder has an inner surface and the inner surface is configured to come into contact with a part of an outer surface of an insertion portion of the endoscope.

22. A cover removal jig kit retrofit to an endoscope system comprising:

an endoscope including:

an insertion portion configured to be inserted into a lumen, the insertion portion includes a first tip cover attached to a distal end of the endoscope;

a cover removal jig configured to remove the first tip cover from the insertion portion of the endoscope, the cover removal jig comprising:

a first enclosing portion configured to encapsulate the first tip cover and having a portion being engageable with the first tip cover; and

a cylinder being flexible and configured to connect to the first enclosing portion capable of coming into a close contact with a part of the insertion portion.
