Conventionally, especially as a method for giving nutrition through a intestine, endoscopic stomach stoma through skin (PEG) which is one of endoscopic operations for forming a stoma in skin surfaces of stomach lumen and abdominal wall using an endoscope was developed by Gaudert (pediatric surgeon) and Ponsky (endoscopic surgeon) in 1979 (Japanese Patent Application Laid-open No.H6-503243), and some techniques using this have been developed and have become widespread. However, since a stomach lining or an abdominal wall is subjected to centesis, this operation can not be used or it is difficult to use this operation “in a case in which a large amount of ascites is stored”, “in a case in which a liver or a transverse colon exists between a stomach and an abdominal wall”, and “a case in which the patient has anamnesis of stomach operation”.
The present inventors proposed an invention of a medical tube inserting tool and a method for using this tool in Japanese Patent Application Laid-open No.H10-17994. In this invention, in order to overcome the inconvenience of the PEG and the tube through nose, a route for discharging bodily fluid and infusing chemical liquid and eutrophic through esophageal is reliably secured with safety. In this invention, however, there is no detail description concerning the tube to be stayed, and since it is necessary to use a long tube when a currently widely used tube is used, a portion of the tube projecting from a body becomes long, this portion is burdensome for a patient who needs the tube in his or her body for a long term. Therefore, there is a possibility that the patient himself or herself intentionally pull out the tube in some cases.
As a method for overcoming the inconvenience caused because the portion of the tube projecting from the body becomes long, there is proposed a medical tool comprising a mushroom-like or semi-spherical member to be fixed in a body. In this medical tool, the projecting portion is reduced in size (U.S. Pat. Nos. 5,549,657, and 4863438). When this proposed tool is allowed to stay in the esophagus, however, there is a problem that the fixed portion becomes bulky at the entrance portion of the esophagus, and it becomes difficult to take nutrition through a mouth.
FIG. 5 is a plan view of an esophagus stoma button of a fifth embodiment of the invention,
FIG. 14 show an esophagus stoma button of a sixth embodiment of the invention wherein FIG. 14(a) is a perspective view thereof and FIG. 14(b) is a partial vertical sectional view of FIG. 14(a),
FIG. 15 show a flange part of an esophagus stoma button of a seventh embodiment of the invention wherein FIG. 15(a) is a perspective view thereof, FIG. 15(b) is a partial vertical sectional view of FIG. 15(a), FIG. 15(c) is a front view showing a state in which a cap is fastened, and FIG. 15(d) is a front view showing one example of a connection tube connector applied to the flange portion of FIG. 15(a),
FIG. 16 are schematic side views showing the tip of a shaft portion in an eighth embodiment of the esophagus stoma button of the invention wherein FIG. 16(a) is a schematic view showing a first embodiment of a weight added on the tip of a shaft, FIG. 16(b) is a schematic view showing a second embodiment of the weight added on the tip of the shaft and FIG. 16(c) is a sectional view of FIG. 16(b),
Concerning the above points, as in embodiments shown in FIGS. 14(b) and 15(b), if an inner hard material (2 h) is integrally covered with soft material (2 s) to form the flange part (2), the same effect can be obtained. In this case, since chemical liquid or eutrophic comes into contact with the hard material, the material which is resistant to chemicals and eutrophic (e.g., fatty emulsion) is required. Preferable materials thereof are polyethylene resin, polypropylene resin, polyvinyl chloride resin, polyurethane resin, polyamide resin, polyether sulfone resin. Since the soft material (2 s) needs appropriate softness as described above, preferable materials thereof are soft vinyl chloride resin, polyurethane resin, polyamide resin or elastomer thereof, or silicone rubber.
In the case of the esophagus stoma button of this invention having the lumen (1 a), the flange portion (2) is provided with a cap portion (3) for keeping the air-tightness. The cap portion (3) may be integrally formed on the flange part (2), or the cap portion (3) may be integrally formed on a cover (5) which covers the flange part (2) as shown in FIG. 3. The shape of the cap portion (3) is not especially limited, but in order to prevent a patient from unintentionally opening the cap portion (3), it is preferable form the cap portion (3) into a curved surface such as substantially domical shape as shown in FIG. 15(c) so that the finger or the nail of the patient can not easily catch. The esophagus stoma button (9) of the invention in the indwelling mode as shown in FIG. 12 is fixed to a patient by one needle suture in some cases. Therefore, as shown in FIGS. 2 and 3, the flange part (2) or the cover (5) may be provided at its outer periphery with a necessary number of small holes (10). Further, as shown in FIGS. 14(a), 14(b), 15(a) and 15(b), a slit (20) may be provided so that the esophagus stoma button can be fixed by a wide band instead of fixing by means of suture.
