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.
Claims30
A medical instrument comprising:
- a first tubular body having a first end for being inserted into a body cavity and a second end, the first tubular body having a severable portion proximate the first end;
- a resilient parasol extending from the first end of the first tubular body, the parasol having a normally opened and a closed position;
- a seal within the severable portion of the first tubular body;
- and
- a second tubular body containing the first tubular body and parasol, the second tubular body having first and second ends corresponding to the first and second ends of the first tubular body, respectively, the second tubular body compressing the parasol and maintaining the parasol in the closed condition when the parasol is within the second tubular body, the first tubular body being movable with respect to the second tubular body such that when the first end of the first tubular body is advanced out of the first end of the second tubular body, the parasol deploys into the normally opened condition.

A medical instrument comprising:
- a first tubular body having a longitudinal axis and a first and a second end, the tubular body having an external surface with a groove therein transverse to the longitudinal axis, wherein the groove and the first end define a severable portion of the first tubular body;
- a resilient parasol for being connected to a viscous internal organ within a body cavity, the parasol extending from the first end of the first tubular body and having a normally opened condition and a closed condition;
- and
- a second tubular body containing the first tubular body and the parasol, the second tubular body having a first and a second end corresponding to the first and the second end of the first tubular body, respectively, the second tubular body compressing the parasol and maintaining the parasol in the closed condition when the parasol is within the second tubular body, the first tubular body being movable with respect to the second tubular body such that when the first end of the first tubular body is advanced out of the first end of the second tubular body, the parasol deploys into the normally opened condition.

A puncture system for puncturing a viscous organ within a human or animal body cavity comprising:
- a first tubular body having a first end for being inserted into a body cavity and a second end, the first tubular body having a severable portion proximate the first end;
- a resilient parasol extending from the first end of the first tubular body, the parasol having a closed condition and a normally opened condition, the parasol being connectable to the viscous organ when in the opened condition;
- a seal within the severable portion of the first tubular body;
- a second tubular body containing the first tubular body and parasol, the second tubular body having first and second ends corresponding to the first and second ends of the first tubular body, respectively, the first tubular body being movable within the second tubular body such that when the parasol is within the second tubular body, the second tubular body compresses the parasol into the closed condition and when the first end of the first tubular body is advanced out of the second tubular body, the parasol returns to the normally opened condition;
- a third tubular body connected to the second end of the first tubular body and extending out of the second end of the second tubular body, for moving the first tubular body within the second tubular body and for advancing the first end of the first tubular body out of the first end of the second tubular body to open the parasol;
- adhesive means for connecting the opened parasol to the organ;
- a needle for puncturing the organ after the parasol is connected to the organ, the needle being insertable through the first tubular body and seal, into the organ;
- cutting means for cutting the severable portion of the first tubular body;
- wherein, after puncturing the organ with the needle and removal of the needle, the severable portion of the first tubular body is cuttable by the cutting means so that the parasol and severable portion of the tubular body are left connected to the organ after the first tubular body is removed.

A kit of parts to provide a medical system, said kit comprising:
- a first tubular body having a first end for being inserted into a body cavity and a second end, the first tubular body having a severable portion proximate the first end;
- a flexible parasol extending from the first end of the tubular body, for being connected to a viscous internal organ within the body cavity, the parasol having a closed condition and a normally opened condition, the parasol being connectable to the organ when in the opened condition;
- a seal within the severable portion of the first tubular body;
- a second tubular body for receiving the first tubular body and parasol, the second tubular body having first and second ends corresponding to the first and second ends of the first tubular body, respectively, the first tubular body being movable within the second tubular body such that when the parasol is within the second tubular body, the second tubular body closes the parasol and when the first end of the first tubular body is advanced out of the second tubular body, the parasol returns to the normally opened condition;
- and
- cutting means for cutting the severable portion of the first tubular body.
