1, the main tube 10 is provided on the outer circumferential surface of the main body 10, which is in close contact with an endoscope (not shown) and moves the bag assembly 60 accommodating the balloon 40 therein. A plurality of leader lines 11 are formed so that the depth to be inserted into the guide lines 11 can be confirmed. Accordingly, the main tube can be prevented from being inserted more than necessary.

The sub tube 20 is for supplying air and sterile water into the balloon 40 through the needle 30 and protrudes from the end of the main tube 10. Such a sub tube 20 supplies a predetermined amount of air and aseptic water to the balloon 40 and then the operator retracts the main tube 10 and retracts the main tube 10 when the sub tube 20 is pulled do.

Fig. 5 is a perspective view showing the needle of Fig. 4, and Fig. 6 is a sectional view of the needle of Fig.

The needle 30 is fixed to the end of the sub tube 20 and includes a needle coupling end 31 which is engaged with and joined to the sub tube 20; A needle body 32 extending from the needle coupling end 31; A needle end 33 formed at the end of the needle body 32 to be rounded; And a needle hole (34) formed in a side of the needle body (32) on the upper side of the needle stage (33).

The needle coupling end 31 is fixedly fixed to the end of the sub tube 20 so that when the operator pulls the sub tube 20 after the procedure is completed, the needle 30 is inserted into the main tube 10 Backward.

The needle body 32 penetrates through the valve 50 to be described later and then enters the balloon 40. When the sub tube 20 is retracted toward the main tube 10 after completion of the procedure, .

The needle end (33) is rounded with its end clogged so that the inner circumferential surface of the balloon (40) is not scratched during the storing process or the procedure.

The needle hole 34 is formed on the side of the needle body 32 on the upper side of the needle end 33 and discharges air and sterile water supplied from the outside through the sub tube 20 through the side portion of the needle body 32 do. The needle hole 34 is located at the center side of the balloon 40, and the discharged air and sterile water gradually inflate the balloon 40 from the center side.

On the other hand, between the needle coupling end 31 and the needle body 32, as shown in Figs. 3 and 4, a first jaw 33 for limiting the depth at which the needle coupling end 31 is inserted into the sub tube 20 And a second jaw 36 for limiting the length in which the needle body 32 is inserted into the valve 50 to be described later is formed. When the needle 30 is fully engaged with the valve 50, the first and second jaws 35 and 36 are provided between the sub-tube 20 and the balloon 40 36 are formed, and as shown in FIG. 10, the sub-tube 20 can be superposed on the surface of the flat balloon 40 to be described later.

The balloon 40 is inserted into the stomach to reduce the gastric volume and is made of a medical polyurethane material. Such a polyurethane-made balloon 40 does not burst even when a strong pressure is applied from the outside while being inserted in the stomach, is not broken by debris when the balloon 40 is removed in the stomach, is excellent in biocompatibility, Strong acidic stomach can withstand long term.

For reference, the balloon 40 is inserted in the stomach for about six months after the procedure, and general rubber, silicone rubber, and the like are difficult to be preserved in a prototype because their physical properties are changed in a strongly acidic environment.

The balloon (40) forms a flat rounded shape when unfolded. 3, a thick balloon bracket end 41 is formed at the center of the balloon 40 as compared to other parts, and a valve 50 described later is coupled to the balloon bracket end 41. [ Since the balloon bracket stage 41 is thicker than other parts, the valve 50 can be disposed in the balloon 40 with the balloon 40 flat.

FIG. 7 is a side view illustrating the valve of FIG. 3; FIG.

The valve 50 is fixedly coupled to the balloon bracket 41 in a state of being embedded in the balloon 40 and temporarily connected to the needle 30 so that the air and the aseptic water flowing through the needle 30 are supplied to the balloon 40 40). The valve 50 is a check valve that automatically closes the flow path when the needle 30 is disengaged. The valve 50 has a valve coupling end 51 that is fixedly coupled to the balloon bracket end 41, And a valve body (52) extending inside the valve body (40).

FIG. 8 is a side view illustrating the bag assembly of FIGS. 1 and 2, and FIG. 9 is a sectional view taken along line IX-IX of FIG.

The pocket assembly 60 is inserted into the stomach together with the endoscope and includes a bag 61 in which the balloon 40 is received in a rolled form and the balloon 40 is torn and broken to expand, And a cap 62 connected to the end of the tube 10.

The pouch 61 exposes the balloon 40 while being sequentially broken from one side to the other side of the balloon 40 when the balloon 40 is inflated. For this purpose, the bag 61 is made of silicone rubber, and the first, second and third fracture inducing holes 61a, 61b and 61c are formed on the side. At this time, the first and second fracture induction holes 61a and 61b of the first, second and third fracture induction holes are formed relatively close to each other. Accordingly, when the balloon 40 expands, 61a (61b) side, the pouch 61 is first torn and broken, and then the third fracture inducing hole 61c side is torn and broken.

The cap 62 connects the pouch 61 with the end of the main tube 10. The cap 62 has an oblique sloped surface 62a to prevent the cap 62 from being injured in the stomach or the esophagus inner wall when the main tube 10 is removed from the body after the procedure is completed.

The pouch 61 remains connected to the cap 62 even after the pouch 61 has been removed so that the debris does not remain in the stomach during the movement of the pocket assembly 60 out of the body.

Figs. 10 and 11 are views for explaining how the flat balloons of Figs. 1 and 2 are curled on both sides around the sub-tube to be accommodated in a pocket, Fig. 12 is a cross- Fig. 3 is a view for explaining that a balloon curled in a bag assembly is accommodated in a pocket assembly.

The balloon bag assemblies 40, 60 in which the curled balloon 40 is received must have a small diameter so that they can pass through a narrow esophagus. Further, a camera (not shown) provided in the endoscope can be used to capture a field of view .

In order to do this, the sub tube 20 is brought into close contact with the surface of the flat balloon 40 before the air is injected in the state where the needle body 32 is coupled to the valve 50 provided at the center of the balloon, After the ends are rolled up, the sub-tubes 20 are superimposed one on top of the other and placed in the pockets 61. Then, as shown in Fig. 12, the balloon-bag assemblies 40, 60 having a small diameter and a long shape are completed, so that even if the balloon-bag assemblies 40, 60 are inserted into the body together with the endoscope, So that accurate operation can be performed.

Then, when the balloon pouch assemblies 40 and 60 are inserted into the stomach and then air and sterile saline are supplied through the sub tube 20, the balloon 40 is expanded while expanding from both sides of the sub tube 20 at the same time.

With the above-described structure, the balloon-bag assembly 40, 60 is inserted into the stomach with the endoscope through the esophagus, and then the balloon-bag assembly 40, 60 is moved to a specific position in the stomach while confirming the endoscope camera.

After the air and aseptic water are injected through the sub tube 20, the balloon 40 is injected into the balloon 40 through the needle 30. The balloon 40 gradually expands and becomes spherical while breaking the pouch 61.

The air and the aseptic water are gradually supplied to the center side of the balloon 40 through the needle hole 34 formed on the side of the needle body 32. As a result, the balloon 40 gradually expands and expands, The third fracture inducing hole 61c is broken after destruction at the 1,2 fracture guide holes 61a and 61b. As a result, fragments can be prevented from being generated while the pouch 61 is broken.

When the air and the sterilized water are completely filled with the balloon 40, the practitioner grasps the main tube 10 and pulls the sub tube 20, so that the balloon 40 is brought into close contact with the cap 62 and the sub tube 20 The needle 30 is detached from the balloon 40 and then is retracted to the inside of the main tube 10. Then, the inflated balloon 40 is separated from the sub-tube 20 and remains inserted in the stomach.

Then, the main tube 10 is pulled out together with the endoscope and separated from the body, thereby completing the procedure. At this time, the cap 62 has an inclined surface 62a, which prevents the cap 62 from being scratched during the esophagus movement.

As described above, according to the present invention, the tube body 20 is brought into close contact with the surface of the flattened balloon 40 while the needle body 32 is coupled to the valve 50 provided at the center of the balloon, 60 can be completed with a small diameter by accommodating both side ends of the tubular body 60 in the form of rolls and being accommodated in the back pouches 61 which are in close contact with the sub-tubes 20 in mutual contact.

As a result, the balloon bag assemblies 40 and 60 do not obscure the field of view of the endoscope camera, so that a view can be secured through the endoscope and the balloon can be accurately and easily inserted into a specific position in the stomach, Can be dramatically reduced.

And a view can be secured through an endoscopic camera, so that a highly specialized technique is not required, and a procedure time can be shortened, thereby reducing a procedure cost.
