Abstract
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 Analysis
Total Claims: 31
Claim 1
Independent Claim
129 words
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.
Claim 2
Independent Claim
129 words
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.
Claim 3
Dependent Claim

Dependent Claim
17 words
The method according to claim 2, further comprising aspirating fluid from the organ through the needle body.
Claim 5
Dependent Claim
22 words
The method according to claim 2, further comprising inserting a camera through the needle body and observing the inside of the organ.
Claim 6
Dependent Claim
30 words
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.
Claim 7
Dependent Claim
32 words
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.
Claim 8
Dependent Claim
34 words
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.
Claim 9
Dependent Claim
26 words
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.
Claim 10
Dependent Claim
40 words
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.
Claim 11
Dependent Claim
