2. Description of the Related Art Conventionally, as a spray for bioadhesives,
For example, a so-called spray type of spraying and mixing two solutions of a solution containing factor XIII and fibrinogen and a thrombin-containing solution is known, which is a chemical solution spraying section with an air supply section and a syringe. It is directly connected to the distal end of the body, and it is considered to perform hemostasis by exfoliating the gallbladder etc. from the living body and then spraying a bioadhesive to the extruding portion in external surgery such as laparotomy. (See JP-A-64-25843 and JP-A-64-40040).

[0003]

However, recently, a surgical method using an endoscope has been developed which has advantages such as less invasion to a patient and quicker recovery than conventional surgical laparotomy. However, in the above nebulizer, since the nebulizer is directly connected to the air supply unit and the tip of the syringe, there is a problem that the nebulizer cannot be used by being connected to the endoscope.

In view of such circumstances, it is an object of the present invention to provide a bio-adhesive sprayer which can be inserted into the abdominal cavity from an introducing tube such as forceps in an operation using an endoscope in the abdominal cavity or the like.

[0005]

SUMMARY OF THE INVENTION A bioadhesive atomizer of the present invention comprises a flexible tube in which one air passage and at least two chemical liquid passages are individually formed, and the flexible tube. And a chemical liquid spraying portion provided at one end of the flexible tube and an air supplying portion for supplying air to the air passage and a chemical liquid to the chemical liquid passage. And a syringe.

[0006]

In the present invention, when the tip of the spray section is inserted from the introduction tube such as the forceps of the endoscope, the flexibility of the tube allows the tip of the spray section to reach the living body ejection point without any resistance. You can When air and a chemical solution are supplied to the spraying part in this state, the bioadhesive is sprayed on the extruded part and the hemostasis of the extruded part can be stopped. In addition, the tube can be set to a desired length according to the position of the bleeding site where hemostasis is to be performed.

Has been done. As shown in FIGS. 2 to 5, the chemical liquid spraying portion 11 is formed by molding one end of a cylindrical body as follows. That is, in the axial direction of the columnar body, a partition plate 13 is formed in the center so that the cross section has a substantially inverted T shape, and a bottom surface 14 perpendicular to the center partition plate 13 is formed on both sides of the center partition plate 13. Has been done. Further, in the direction perpendicular to the axial direction of the columnar body, the central partition plate 13 and the back surface 15 perpendicular to the bottom surface 14 are formed. A chemical solution outlet 16 is formed on the bottom surface 14, and an air outlet 17 is formed on the back surface 15 on both sides of the central partition plate 13.

Further, in the air chemical liquid passage portion 12, an air passage 18, an air reservoir 19 and two air passages 20 for dividing the air in the air reservoir 19 into two are formed above the inside of the cylindrical body. A chemical liquid passage 21 is formed below the inside of the cylindrical body. The tip of the air passage 20 is connected to the air outlet 17 and
The tips of 21 respectively form the chemical liquid outlets 16.
It should be noted that the air reservoir 19 is a rectangular parallelepiped, which temporarily stores the air that has flowed in from the air passage 18 and then divides the air into two parts. Has the function of causing turbulence in the flow of the liquid and, as a result, allowing the two liquids to mix well.

The spray section 1 may be made of any material as long as it has high biocompatibility and excellent workability, such as polypropylene, polyethylene, ABS resin, polyvinyl chloride, polyester, polystyrene or the like. A metal such as a plastic resin or stainless steel is used.

A cylindrical flexible tube 2 having an outer diameter of about 3 to 15 mm and a length of about 300 to 500 mm is connected to the rear end of the spray section 1. As shown in FIG. 6, an air passage 18 and two chemical liquid passages 21 and 22 are formed axially through the inside of the tube 2, and the tip of the air passage 18 and the two chemical liquid passages 21 and 22 are formed in the spray section 1. It is connected to the passage 18 and the chemical liquid passages 21 and 22, respectively (see FIG. 7). The connection between the spray unit 1 and the tube 2 is shown in FIG.
As shown in FIG. 1, the tip of the tube 2 is inserted into the rear end of the spraying section 1 and further fixed with an appropriate adhesive or the like. The thickness and length of the tube 2 can be arbitrarily selected according to the application, and the chemical liquid passage 21 of the tube 2 can be selected.
It is also possible to mix chemical liquids such as three liquids or four liquids by increasing the number of small holes for use. Further, although the air passage 18 and the chemical liquid passages 21 and 22 are formed in the cylindrical tube 2 as shown in FIG. 6, the air line 31 and the chemical liquid which will be described later are provided in the hollow portion of the cylindrical tube. The lines 41, 42 may be inserted. The material of the tube 2 is preferably one that has a flexibility such that it can be easily deformed when it is inserted into the abdominal cavity or the like, and has an appropriate rigidity. For example, polyethylene, soft polyvinyl chloride, polyester, Thermoplastic resins such as silicone rubber and polyurethane rubber are suitable.

An air line 31 is connected to the air passage 18 at the rear end of the tube 2 as shown in FIG. 1, and the air line 31 is connected to another air line 33 by a joint 32.

Therefore, if a doctor or the like pushes the plungers 47 and 48 of the syringe 4, one of the liquid medicines passes through the liquid medicine line 41 and the liquid medicine passage 21, and the other liquid medicine passes through the liquid medicine line 42 and the medicine liquid passage 22, It is ejected from the chemical liquid outlets 16a and 16b, respectively. Then, at this time, the chemical liquids ejected from the respective chemical liquid outlets 16a and 16b are atomized and mixed by the air ejected from the air outlet 17 and sprayed as a bioadhesive. Alternatively, the spraying section 1 and the tube 2 may be integrally formed into one unit.

Next, the bioadhesive atomizer A of this embodiment is used.
How to use is explained. First, the tip of the spraying section 1 is inserted from an introduction tube such as forceps of an endoscope, and the tube 2 is held in the middle by hand and pushed in slowly. Then, when the tip of the spraying section 1 reaches the living body ejection portion, the plunger of the syringe 4
47 and 48 are simultaneously pushed through the stopper 52 to eject two types of chemicals from the chemical outlets 16a and 16b, and the air sent from the air supply device is ejected from the air outlet 17.
The chemical liquid spraying section 11 mixes and sprays the chemical liquid in a mist state. By doing so, the bio-adhesive is sprayed on the living-body exfoliation site,
Hemostasis can be performed. Further, after the spraying, the tip of the spraying section 1 can be easily taken out through the introducing tube such as the forceps of the endoscope, so that the inner wall of the living body is not damaged.
