Abstract

The present invention relates to a puncture method and a puncture system. More specifically, the objective of the present invention is to carry out the aspiration of a sample from a human organ or an animal organ and the inner examination thereof, without the outward leak of the fluid and the like in the organ.

The puncture method and puncture system of the present invention is in the following structure; making a parasol part arranged on a reservoir adhere through an adhesive to the site to be punctured, inserting a needle body through a sealing part of the reservoir into the site to be punctured to draw out the inner fluid, the leak of the fluid can be prevented by the reverse operation of the sealing part.

Claims

1. A method for puncturing a site on an internal body organ with an instrument having a tubular body with a proximal end and a distal end, a sealing portion proximate the distal end for sealing at least a portion of the tubular body, and a resilient parasol portion extending from the distal end, the method comprising:

inserting the distal end of the tubular body including the parasol portion into a body cavity containing the organ;

advancing the parasol portion within the body cavity to the site;

supplying an adhesive onto one of the site and the parasol portion;

adhering the parasol portion to the site with the adhesive; and

puncturing the site by inserting a needle body through the sealing portion of the tubular body and through the site.

2. The method according to claim 1, wherein the parasol portion has a normally opened position and the first tubular body is contained within a second tubular body having a distal portion, the second tubular body compressing the resilient parasol portion into a closed position when the parasol portion is contained within the second tubular body, the method further comprising inserting the distal portion of the second tubular body through a wall of the body cavity, and advancing the distal end of the first tubular body, including the parasol portion, out of the distal portion of the second tubular body, thereby allowing the parasol portion to return to its normally opened position within the body cavity.

3. The method according to claim 2, further comprising aspirating fluid from the organ through the needle body.

4. The method according to claim 2, further comprising inserting a camera through the needle body and observing the inside of the organ.

5. The method according to claim 2, further comprising inserting a sample collector through the needle body and collecting a part of the inside of the site by the sample collector.

6. The method according to claim 2, further comprising cutting the tubular body proximate the distal end and leaving the distal end of the tubular body and the parasol portion on the site.

7. A method according to claim 2, wherein the adhesive is provided in a bag extending from the distal end, the method further comprising supplying the adhesive by cutting the bag to release the adhesive.

8. The method according to claim 2, further comprising inserting an adhesive feeding jig into the body cavity and supplying the adhesive from the adhesive feeding jig.

9. The method according to claim 2, wherein the adhesive is provided in a reservoir within the tubular body, the reservoir being sealed by a plug, the method further comprising supplying the adhesive by removing the plug from the tubular body.

10. The method of claim 2, further comprising drying the site prior to adhering the parasol portion to the site.

11. The method of claim 2, wherein the parasol portion has an inner surface, the method further comprising supplying the adhesive to the inner surface and adhering the inner surface to the site.

12. The method according to claim 1, further comprising aspirating fluid from within the organ through the needle body.

13. The method according to claim 1, further comprising inserting a camera through the needle body and observing the inside of the organ.

14. The method according to claim 1, further comprising inserting a sample collector through the needle body and collecting a part of the inside of the organ by the sample collector.

15. The method according to claim 1, further comprising cutting the tubular body proximate the distal end and leaving the distal end of the tubular body and the parasol portion on the site.

16. The method according to claim 1, wherein the parasol portion has an opened and a closed position and the adhesive is provided in a bag extending from the distal end of the first tubular body, within a region defined by an inner surface of the parasol portion when the parasol portion is in the closed position, the method further comprising opening the parasol portion when the parasol portion is within the body cavity and supplying the adhesive by cutting the bag to release the adhesive.

17. The method according to claim 1, further comprising inserting an adhesive feeding jig into the body cavity and supplying the adhesive from the adhesive feeding jig.

18. The method according to claim 1, wherein the adhesive is provided in a reservoir within the tubular body, the reservoir being sealed by a plug, the method further comprising supplying the adhesive by removing the plug from the tubular body.

19. The method of claim 1, further comprising drying the site prior to adhering the parasol portion to the site.

20. The method of claim 1, wherein the parasol portion has an inner surface, the method further comprising supplying the adhesive to the inner surface and adhering the inner surface to the site.

21. A method for puncturing a site on an internal body organ comprising:

inseting a distal end of a tubular body into a body cavity containing the organ, the distal end having a resilient parasol portion extending therefrom;

adhering a surface of the parasol to the site on the internal body organ; and

inserting a needle body through the tubular body and through the site, thereby puncturing the site.

22. The method of claim 21, wherein the parasol portion has a normally opened and a closed condition, the method further comprising inserting the parasol portion into the body cavity in the closed condition and then opening the parasol portion within the body cavity prior to adhering the parasol portion to the site.

23. The method of claim 22, further comprising applying adhesive to the site prior to adhering the parasol portion to the site.

24. The method of claim 23, further comprising drying the site prior to applying the adhesive.

25. The method of claim 22, further comprising applying adhesive to the surface of the parasol portion prior to adhering the surface of the parasol portion to the site.

26. The method of claim 25, further comprising drying the site prior to adhering the surface of the parasol portion to the site.

27. The method of claim 21, further comprising aspirating fluid from within the organ through the needle body.

28. The method of claim 27, further comprising cutting a portion of the tubular body proximate the parasol portion and leaving the cut portion of the tubular body and the parasol portion on the site, after aspirating the fluid.

29. The method of claim 21, further comprising cutting a portion of the tubular body proximate the parasol portion and leaving the cut portion of the tubular body and the parasol portion on the site, after puncturing the site.
