に使用する医療用具に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is used to support the anastomosis by inserting it into the anastomosis site when anastomosing hollow organs such as blood vessels and intestinal tracts. Regarding medical equipment.
［従来の技術］

点がある。[Prior Art] As a method of anastomosing hollow organs such as blood vessels and intestinal tracts, the method of simply suturing the anastomosis with suture thread has been used for a long time, but since the organs are soft, it is difficult to suture them. There were many difficulties, especially when dealing with small-diameter blood vessels. Therefore, there was a problem in that the surgery required experience and skill and took a long time. Therefore, in order to improve such problems, Japanese Unexamined Patent Publication No. 61-217170 and Utility Model Application No. 61. No. 29720 discloses a tool for assisting an anastomosis operation. These tools are made from bioabsorbable materials, so they maintain their strength until the hollow organs fuse together after surgery, and they disappear after a certain period of time, so they have the advantage that they do not remain as foreign objects in the body. There is.

いう問題があった。Conventional hollow organ anastomosis tools were simply molded polymer materials, which had a problem in that the surface was smooth and the living organ was easily soaked during anastomosis, making it difficult to fix the tool to the anastomosis site. In other words, there are problems in that during the anastomosis, the position may shift and the procedure must be repeated several times, or the tool may become displaced from the anastomosis even if the tool is tied around with suture to secure the hollow organ and the tool. there were.

った。Therefore, the present inventors invented a tool that facilitates fixation of hollow organs by providing a circumferential protrusion on the outer surface of the tool, and published Japanese Patent Application No. 62-230791 (Japanese Unexamined Patent Publication No. 12-72737). ) and applied for a patent. In this Kawanaga, remarkable effects could be obtained by adopting the anastomosis method described therein. However, it has been found that when used in the following anastomosis method, which is adopted as an efficient anastomosis force method in some cases, the -1- minute effect is not exhibited7. That is, the tool is extrapolated onto one of the hollow organs to be anastomosed, the end of the organ is inverted, the end of the other hollow organ is extrapolated onto the -L to bring the inner surfaces of the organs into close contact, and the -L When used in the anastomosis method of tying with empty string, the fixation of the hollow organs together was somewhat inefficient.
本発明は、上記の吻合方法に適した用具を提供すること
を目的とするものである。An object of the present invention is to provide a tool suitable for the above-mentioned anastomosis method.

を特徴とする中空器官吻合用具用具である。In the present invention, by expanding the diameter of one end of the tool,
The above objectives were achieved. That is, the present invention provides a cylindrical tool for supporting the anastomosis part and assisting the anastomosis when two hollow organs are anastomosed, the hollow organ anastomosis being characterized in that one end of the cylindrical body is enlarged in diameter. Tools are tools.

Extrapolate the other hollow organ to that ten and tie it with thread from around it. In this way, as shown in FIG. 2, even if the hollow organs are pulled together, the enlarged diameter portion of the tool prevents the portion tied with thread from falling off. Therefore, it will be firmly fixed.

As shown in the figure, the tool 1 has a cylindrical shape, and one end 2 has an enlarged diameter in the shape of a funnel. FIG. 2 shows a cross-sectional view of a hollow organ anastomosed using this tool. '' = As mentioned above, first insert the tool 1 of the present invention outside one of the hollow organs 3 with the enlarged diameter part facing the end of the hollow organ, and then invert the end 4 of the hollow organ. Lay it on the utensil with the inside facing out. next,
3. Extrapolate the end 6 of the other hollow organ 5 as it is and overlap it,
Tie it with string 7 from above. By doing this,
Since the diameter of the end 2 of the tool is larger than the diameter of the thread 7, even if a force is applied in the direction of pulling the hollow organs together, they will not easily come off.
