Description

Technical Field

[0001] The present invention relates to a balloon packaging body with a mounting fixture and a balloon mounting method, and in particular to a balloon packaging body with a mounting fixture for mounting the balloon on an insertion portion of an endoscope and a balloon mounting method. Background Art

[0002] In an endoscope device, an inflatable and deflated balloon is used for various purposes. For example, in an endoscope device for observing a deep digestive tract such as the small intestine or the large intestine, an inflatable and deflated balloon is installed at the insertion portion of the endoscope, and the insertion portion of the endoscope can be fixed in the body by inflating the balloon.

[0003] This balloon is made of an elastic body such as rubber, and its end is formed into a cylindrical shape with a diameter smaller than the outer diameter of the object to be installed (the insertion part of the endoscope) in a natural state. In addition, when installing the balloon, the diameter of the end of the balloon is enlarged and it is placed on the object to be installed, and then a wire is wound from above the end of the balloon or a rubber band is inserted outside, thereby fixing the end of the balloon to the object to be installed.

[0004] However, the work of enlarging the diameter of the end of the balloon while putting it on the installation object is very cumbersome, and there is a problem that the installation work takes labor and time. For example, the following patent document 1 describes a balloon installation fixture, which has a retaining portion at both ends of the installation fixture body to retain the opening of the balloon inserted into the inner cavity of the installation fixture body. The balloon installation fixture retains the opening of the balloon by the retaining portion of the installation fixture body, and installs the balloon in the insertion portion of the endoscope by externally fitting the balloon to the installation fixture body.

[0005] In addition, Patent Document 2 describes a balloon installation jig having a first guide piece and a second guide piece inserted into a tube provided at both ends of a balloon body. The balloon installation jig inserts an endoscope into the tube of the balloon by inserting an insertion portion of the endoscope between the first guide piece and the second guide piece.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2005-230084

[0007] Patent Document 2: Japanese Patent Application Publication No. 2009-011656

[0008] However, the mounting fixtures described in Patent Documents 1 and 2 are manually mounted on the insertion portion of the endoscope after the balloon placed in the bag is mounted on the mounting fixture. In this work, gloves are worn to maintain the sterility of the balloon, so the work is cumbersome, labor-intensive and time-consuming. In addition, the balloon is effortlessly placed in the bag, so the balloons are tightly contained in the bag due to the stickiness (viscosity) of the balloon surface. Therefore, the balloon needs to be carefully peeled off before being mounted on the endoscope, which is also a major reason for wasting time in the work. Summary of the invention

[0009] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a balloon package with a mounting jig and a balloon mounting method that can reduce the workload of mounting the balloon on an insertion portion of an endoscope.

[0010] In order to achieve the purpose of the present invention, the present invention relates to a packaging body of a balloon with a mounting clamp, which is a balloon mounting clamp for mounting a balloon on an insertion portion of an endoscope and a packaging body of a balloon with a mounting clamp in which the balloon is accommodated in a storage container, wherein the balloon comprises: a first barrel portion, which is arranged at one end of the balloon; a second barrel portion, which is arranged at the other end of the balloon; and a balloon body, which is arranged between the first barrel portion and the second barrel portion, and the balloon mounting clamp comprises: a body portion, which is formed into a hollow cylindrical shape and can be folded into a flat shape, and A balloon body of the balloon is folded inwardly inside the accommodating container, and a second barrel is arranged on the inner side of a folded opening formed in the folded portion of the balloon, and a pair of guide pieces and at least a part of the main body of the balloon mounting fixture are inserted from the folded opening, and a pair of guide pieces are arranged on the inner sides of the first barrel and the second barrel.

[0011] In order to achieve the purpose of the present invention, the balloon installation method involved in the present invention is a balloon installation method using the packaging body of the balloon with the installation clamp described above, wherein the endoscope insertion part is inserted into the main body from the first opening, the endoscope insertion part is inserted between a pair of guide pieces, and the endoscope insertion part is inserted into the first barrel and the second barrel via the pair of guide pieces, the balloon, the balloon installation clamp and the endoscope insertion part are taken out from the storage container, and with the first barrel fixed to the endoscope insertion part, the second barrel and the balloon installation clamp are moved toward the base end side of the endoscope insertion part, the balloon installation clamp is removed from the second barrel, and the balloon is installed on the endoscope insertion part.

[0012] Effects of the Invention

[0013] According to the packaging body of the balloon with the mounting clamp of the present invention, the balloon body is folded inwardly in the containing container, and the second cylinder portion is arranged on the inner side of the folded-back opening portion, thereby being able to accommodate the balloon and the balloon mounting clamp in a state where a pair of guide pieces of the balloon mounting clamp are inserted into the first cylinder portion and the second cylinder portion.

[0014] Furthermore, according to the balloon installation method using the balloon package with the installation jig, the endoscope insertion part is inserted from the first opening of the balloon installation jig, thereby inserting the endoscope insertion part into the first barrel and the second barrel via a pair of guide pieces. Then, the balloon, the balloon installation jig, and the endoscope insertion part are taken out of the storage container, and the second barrel is moved together with the balloon installation jig, thereby moving the second barrel to a predetermined position, so that the balloon can be easily installed on the endoscope.

[0036] Hereinafter, a balloon packaging body with a mounting jig and a balloon mounting method according to the present invention will be described with reference to the accompanying drawings.

[0037] Figure 1 1 is a system configuration diagram showing an example of an endoscope device using a balloon contained in a balloon package with a mounting fixture according to the present invention. Figure 1 As shown, the endoscope device is mainly composed of an endoscope 10 , a balloon 60 , and a balloon control device 70 .

[0038] The endoscope 10 includes an operation portion 14 and an insertion portion 12 connected to the operation portion 14 and inserted into the body. A universal cord 16 is connected to the operation portion 14, and an LG connector 18 is provided at the front end of the universal cord 16. The LG connector 18 is detachably connected to a light source device 20, thereby transmitting illumination light to an illumination window (not shown) provided at the front end of the insertion portion 12. In addition, an electric connector 24 is connected to the LG connector 18 via a cable 22, and the electric connector 24 is detachably connected to a processor 26.

[0039] The operation portion 14 includes an air and water supply button 28 , a suction button 30 , a shutter button 32 , and a function switching button 34 , and also includes a pair of angle buttons 36 , 36 .

[0040] The insertion portion 12 is composed of a flexible portion 40, a curved portion 42, and a distal end portion 44 in order from the operation portion 14. The flexible portion 40 is formed by wrapping a mesh around the outer periphery of a spirally wound metal plate to cover the outer periphery, and has sufficient flexibility.

[0041] The bending portion 42 is configured to be remotely bent by rotating the angle knobs 36, 36 of the operating portion 14. For example, the bending portion 42 is connected to a plurality of cylindrical node rings by a pin so as to be freely rotatable, and a plurality of operating wires are inserted through the inside of the node rings and guided to the pins. Moreover, by pushing and pulling the operating wires, the node rings are rotated relative to each other, so that the bending portion 42 is bent. By bending the bending portion 42, the front end portion 44 can be directed in a desired direction.

[0042] like Figure 2 As shown, an observation window 52, ​​lighting windows 54, 54, air and water supply nozzles 56 and a forceps mouth 58 are provided on the front end surface of the front end portion 44. An observation optical system and an imaging element such as CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charge Coupled Device) are arranged behind the observation window 52, ​​and a signal cable is connected to the substrate supporting the imaging element. The signal cable is inserted through the insertion portion 12, the operation portion 14 and the universal cord 16, etc. and extended to the electrical connector 24, and connected to the processor 26. Therefore, the observation image read from the observation window 52 is imaged on the light receiving surface of the imaging element and converted into an electrical signal, which is output to the processor 26 via the signal cable and converted into a video signal. As a result, the observation image is displayed on the monitor 50 connected to the processor 26.

[0043] The illumination window 54 is provided with an illumination optical system and an exit end of a light guide (not shown) at its rear. The light guide is inserted through the insertion portion 12, the operation portion 14 and the universal cord 16, and its entrance end is provided in the LG connector 18. Therefore, by connecting the LG connector 18 to the light source device 20, the illumination light emitted from the light source device 20 is transmitted to the illumination optical system via the light guide, and is emitted forward from the illumination window 54.

[0044] The air supply and water supply nozzle 56 provided at the front end portion 44 is communicated with a valve (not shown) operated by the air supply and water supply button 28. The valve is communicated with the air supply and water supply connector 48 provided at the LG connector 18. An air supply and water supply mechanism (not shown) is connected to the air supply and water supply connector 48, which supplies air and water. Therefore, by operating the air supply and water supply button 28, air or water is sprayed from the air supply and water supply nozzle 56 toward the observation window 52.

[0045] The forceps opening 58 provided at the front end portion 44 is communicated with the forceps insertion portion 46. Therefore, by inserting a treatment tool such as forceps from the forceps insertion portion 46, the treatment tool can be led out from the forceps opening 58. In addition, the forceps opening 58 is communicated with a valve (not shown) operated by the suction button 30, and the valve is connected to the suction connector 49 of the LG connector 18. Therefore, by connecting a suction mechanism (not shown) to the suction connector 49 and operating it with the suction button 30, a lesion or the like can be suctioned from the forceps opening 58.

[0046] A balloon 60 is detachably mounted on the outer periphery of the insertion portion 12 of the endoscope 10. The balloon 60 is made of an elastic material such as silicone rubber. The balloon 60 has a first barrel 60A disposed at one end, a second barrel 60B disposed at the other end, and a balloon body 60C disposed between the first barrel 60A and the second barrel 60B. The first barrel 60A and the second barrel 60B are formed into a substantially cylindrical shape that is reduced relative to the balloon body 60C.

[0047] The balloon 60 is arranged at a predetermined installation position (for example, from the front end portion 44 to the curved portion 42) by inserting the insertion portion 12 through the endoscope 10. The first barrel 60A and the second barrel 60B are configured to have an inner diameter smaller than the outer diameter of the insertion portion 12 of the endoscope 10 in a natural state. When the balloon 60 is installed in the insertion portion 12, the elastic force of the first barrel 60A and the elastic force of the second barrel 60B act toward the radial inner side of the insertion portion 12. The balloon 60 is maintained at a predetermined position of the insertion portion 12 by the elastic force.

[0048] A rubber band as a first balloon fixing part 61 in a cylindrical shape is embedded in the outer periphery of the first barrel 60A, and a rubber band as a second balloon fixing part 62 in a cylindrical shape is embedded in the outer periphery of the second barrel 60B. The balloon 60 is fixed to the insertion part 12 by the first balloon fixing part 61 and the second balloon fixing part 62. The package of the balloon with a mounting fixture of the present invention includes the balloon 60 and a balloon mounting fixture for mounting the balloon 60 on the insertion part 12, and its description will be described later.

[0049] A vent hole 64 is formed at the balloon mounting position of the insertion portion 12. Figure 1 The balloon air supply port 38 of the operation part 14 shown in the figure is connected. Figure 1 The balloon 60 is provided with a hose 80, and a balloon control device 70 is connected via the hose 80. The balloon control device 70 is a device for supplying or sucking a fluid such as air into the balloon 60. By supplying or sucking a fluid (such as air) from the balloon control device 70, air can be supplied or sucked into the balloon 60. The balloon 60 is expanded into a substantially spherical shape by the supply of air, and adheres to the outer surface of the insertion portion 12 by sucking air.

[0050] like Figure 1 As shown, the balloon control device 70 is mainly composed of a device body 72 and a manual switch 74 for remote control. A power switch SW1, a stop switch SW2, and a pressure display unit 76 are provided on the front surface of the device body 72. The pressure display unit 76 is a panel that displays the pressure value of the balloon 60. When an abnormality such as balloon rupture occurs, an error code is displayed on the pressure display unit 76.

[0051] A hose 80 for supplying and sucking air to the balloon 60 is connected to the front surface of the device body 72. A backflow prevention unit 82 for preventing backflow of body fluid when the balloon 60 is damaged is provided at the connection portion between the hose 80 and the device body 72. The backflow prevention unit 82 is constructed by assembling a gas-liquid separation filter inside a hollow disc-shaped housing (not shown) that is detachably mounted on the device body 72, and the filter prevents liquid from flowing into the device body 72.

[0052] On the other hand, the manual switch 74 is provided with various switches. For example, a stop switch similar to the stop switch SW2 on the device body 72 side, an ON / OFF switch for instructing the pressurization and depressurization of the balloon 60, a pose switch for maintaining the pressure of the balloon 60, etc. are provided. The manual switch 74 is electrically connected to the device body 72 via a cord 84. Figure 1 Although not shown, the manual switch 74 is provided with a display unit indicating the inflation state or deflation state of the balloon 60 .

[0053] The balloon control device 70 supplies air to the balloon 60 to expand it, and controls the air pressure to a constant value to keep the balloon 60 in an expanded state. Also, air is sucked from the balloon 60 to deflate it, and controls the air pressure to a constant value to keep the balloon 60 in a deflated state.

[0054] The balloon control device 70 is connected to the balloon-dedicated monitor 86, and when the balloon 60 is inflated and deflated, the pressure value or the inflated and deflated state of the balloon 60 is displayed on the balloon-dedicated monitor 86. In addition, the pressure value or the inflated and deflated state of the balloon 60 may be superimposed on the observation image of the endoscope 10 and displayed on the monitor 50.

[0055] As an example of an operation method of an endoscope device, the insertion portion 12 is gradually inserted in a push-in manner, and the balloon 60 is inflated as needed to fix the insertion portion 12 in the body (e.g., the large intestine). Moreover, after the insertion portion 12 is pulled out to simplify the tubular shape of the body (e.g., the large intestine), the balloon 60 is deflated to further insert the insertion portion 12 into the deep part of the intestine. For example, the insertion portion 12 is inserted from the anus of the subject, and when the front end of the insertion portion 12 passes through the sigmoid colon, the balloon 60 is inflated to fix the insertion portion 12 in the intestine, and the insertion portion 12 is pulled out to make the sigmoid colon roughly straight. Moreover, the balloon 60 is deflated to gradually insert the front end of the insertion portion 12 into the deep part of the intestine. In this way, the insertion portion 12 can be inserted into the deep part of the intestine. In addition, the above-mentioned endoscope 10 can be used together with an insertion auxiliary tool with a balloon (not shown) as a double-balloon endoscope device.

[0056] [Balloon package with mounting fixture]

[0057] Next, the package of the balloon with the mounting fixture according to the present embodiment is described. The package of the balloon with the mounting fixture is used to easily mount the balloon 60 on the insertion portion 12 of the endoscope 10. The package of the balloon with the mounting fixture is composed of a balloon mounting fixture for mounting the balloon 60 on the insertion portion 12 of the endoscope 10 and the balloon 60 contained in a container.

[0058] The inner diameter of the first barrel 60A and the second barrel 60B of the balloon 60 is smaller than the outer diameter of the insertion portion 12 in the natural state, and it is difficult to insert the insertion portion 12 through in the natural state. According to the package of the balloon with the mounting fixture involved in this embodiment, the balloon is contained in the storage container in a state where the mounting fixture is installed on the balloon, so the work of installing the balloon mounting fixture on the balloon can be omitted. In addition, the balloon mounting fixture can be easily installed in the endoscope, which can reduce the burden on the staff. In addition, the natural state refers to a state without the action of external force. The first barrel 60A and the second barrel 60B are in an unexpanded and uncontracted state.

[0059] (Balloon mounting fixture)

[0060] First, the balloon mounting jig will be described. Figure 3 is a top view of the balloon mounting fixture. Figure 4 This is a perspective view of a state in which the first opening and the second opening of the main body are opened. Figure 5 This is a perspective view of a state where the main body is folded.

[0061] The balloon mounting fixture 100 has a main body 102 formed in a hollow cylindrical shape, and the main body 102 has a first opening 104 at one end and a second opening 106 at the other end. The second opening 106 of the main body 102 has a pair of guide pieces 108a and 108b that are opposite to each other with the second opening 106 interposed therebetween. Furthermore, two groups of bending portions 110a, 110b, and 110c that are arranged from one end toward the other end and that enable the main body 102 to be bent inward from two directions are formed in the main body 102. By mountain folding the bending portions 110a and 110c and valley folding the bending portion 110b, the main body 102 can be bent inward. Furthermore, by bending the bending portions 110a, 110b, and 110c, the main body 102 can be folded into a flat shape, such as Figure 5 As shown, the pair of guide pieces 108a and 108b can be overlapped.

[0062] A pair of guide pieces 108a, 108b are provided so as to extend from the second opening 106 toward the front end side on the side opposite to the first opening 104. The width of the pair of guide pieces 108a, 108b is formed to be narrower than the width of the main body 102 folded into a flat shape. Thus, when the balloon mounting jig 100 is mounted on the balloon 60, the pair of guide pieces 108a, 108b can be arranged on the inner side of the first barrel 60A and the second barrel 60B of the balloon 60. When the insertion portion 12 of the endoscope 10 is mounted on the balloon 60, the insertion portion 12 can be easily inserted into the first barrel 60A and the second barrel 60B by inserting it along the pair of guide pieces 108a, 108b.

[0063] The main body 102 has a wing 112 extending from the first opening 104 and having a width wider than the main body 102 folded into a flat shape. When the main body 102 is folded, the wing 112 is formed to extend from only one side of the opposite end of the first opening 104, but may be formed from both sides. The wing 112 is contained in a container (see FIG. 1 ) described later. Figure 8 ) when the wing portion 112 abuts against the recess, thereby preventing the main body 102 from moving and rotating.

[0064] The material of the main body 102 and the pair of guide pieces 108a, 108b is preferably a material that is difficult to adhere to rubber products such as silicone rubber and latex, which are materials of the balloon. Specifically, paper such as drawing paper and Kent paper or resins such as fluororesin, silicone resin, polypropylene resin and polycarbonate resin can be used. When formed of paper, it is preferable to use Yupo paper (registered trademark) which is easy to expand or fold the main body 102 and difficult to break.

[0065] (State of the balloon and the balloon mounting fixture in the container)

[0066] Next, the state of the balloon 60 and the balloon mounting jig 100 in a storage container to be described later will be described. Figure 6 2 is a diagram for explaining a balloon with a mounting jig. The balloon with a mounting jig 200 is formed by mounting a balloon mounting jig 100 on a balloon 60 .

[0067] When the balloon installation jig 100 is installed on the balloon 60, first, a pair of guide pieces 108a and 108b are inserted into the second barrel 60B, and the front end side portions of the pair of guide pieces 108a and 108b are made to protrude from the second barrel 60B. Then, the pair of guide pieces 108a and 108b are gradually inserted into the inner side of the balloon body 60C, whereby the second barrel 60B moves toward the first barrel 60A side, and the balloon body 60C is folded back inwardly, thereby forming the folded opening 66. Furthermore, the guide pieces 108a and 108b and the main body 102 are further inserted from the folded opening 66, whereby the front end side portions of the guide pieces 108a and 108b protruding from the second barrel 60B are inserted into the first barrel 60A, and the balloon installation jig 100 is installed on the balloon 60.

[0068] like Figure 6 As shown, in a state where the balloon mounting fixture 100 is installed on the balloon 60, the second barrel portion 60B is arranged on the inner side of the folded-back opening 66. Regarding the pair of guide pieces 108a, 108b, the front end sides of the guide pieces 108a, 108b are arranged on the inner side of the first barrel portion 60A. And, the base end sides of the guide pieces 108a, 108b are arranged on the inner side of the second barrel portion 60B. As shown in the FF section 202, the pair of guide pieces 108a, 108b in the first barrel portion 60A are arranged along the length direction A (reference Figure 3 ) is bent outwardly. Thus, in the accommodation state of the balloon mounting fixture 100, the first opening 104 can be slightly opened from the completely folded state. Therefore, the insertion portion 12 of the endoscope 10 can be easily inserted into the first opening 104.

[0069] In the storage container, the balloon body 60C of the balloon 60 is folded back inward, so that the inner sides of the balloon body 60C are in contact with each other and are contained. As a manufacturing method of the balloon 60, for example, after the mold is immersed in a resin solution that becomes the material of the balloon, it is taken out from the resin solution and dried, thereby forming a balloon around the mold. Then, the balloon is manufactured by taking out the mold from the inside of the balloon. Fine concave and convex are formed on the outer surface of the mold, and the inner side of the balloon 60 contacts the mold during manufacturing, so the fine concave and convex are transferred and given texture. Therefore, when the inner surfaces of the balloon 60 contact each other, even if there is stickiness (viscosity), it will not stick, and a stable shape can be maintained. In addition, since a balloon mounting fixture 100 is configured in the folded opening 66 of the balloon 60, it is also possible to prevent the surfaces of the balloon 60 from contacting each other and sticking. Thus, it is possible to prevent the surfaces from sticking to each other when the balloon 60 is taken out of the storage container.

[0070] (Container)

[0071] Next, the storage container for storing the balloon 200 with the mounting jig will be described. Figure 7 It is a three-dimensional diagram of the container. Figure 8 This is a top view with the cover removed. Fig. 9 is a cross-sectional view of a state in which a balloon with a mounting fixture is accommodated in a storage container. Fig.10 This is a view viewed from the bottom side.

[0072] The storage container 300 has a bottomed cylindrical body 302, a small groove portion 306 provided at the bottom 304 of the body 302 and having an inner diameter smaller than the inner diameter of the body 302, and a container opening portion 308 provided on the opposite side of the bottom 304. A recessed portion 310 formed in a concave shape in a direction perpendicular to the insertion direction B of the balloon mounting jig 100 is provided on the container opening portion 308 side of the body 302. In addition, the container opening portion 308 has a flange portion 312 provided to expand from the container opening portion 308 in a direction perpendicular to the insertion direction B of the balloon mounting jig 100, and a cover portion 314 is attached to the flange portion 312.

[0073] When the balloon 200 with the mounting jig is accommodated in the accommodating container 300, the balloon body 60C and the second tube 60B of the balloon 60 are accommodated in the trunk 302, and the first tube 60A is accommodated in the small groove 306. By accommodating the balloon body 60C in the trunk 302, the balloon bodies 60C arranged around the balloon mounting jig 100 can be prevented from sticking to each other, and the shape of the balloon body 60C can be maintained.

[0074] The body 302 is preferably formed in a tapered shape with an inner diameter that increases from the bottom 304 toward the container opening 308. By setting the tapered shape that increases toward the container opening 308, the balloon 200 with the mounting jig can be easily taken out. In addition, even when manufacturing the storage container 300, the container opening 308 can be expanded to make it easier to pull out from the mold.

[0075] The maximum inner diameter L1 of the trunk portion 302 is preferably set to be greater than or equal to 102% and less than or equal to 110% of the outer diameter of the balloon body 60C in the natural state. By setting the inner diameter L1 of the trunk portion 302 within this range, the balloon 200 with the mounting fixture can be easily placed in the storage container 300. In addition, the balloon 200 with the mounting fixture can be prevented from moving in the storage container 300. When the trunk portion 302 is set to a tapered shape whose inner diameter increases toward the container opening 308, the inner diameter L1 of the trunk portion 302 at the container opening 308 becomes the largest inner diameter.

[0076] The small groove 306 accommodates the first barrel 60A and the pair of guide pieces 108a, 108b. The cross-sectional shape of the small groove 306 cut along the direction C perpendicular to the axial direction of the trunk 302 (the same direction as the insertion direction B of the balloon mounting fixture 100) is an ellipse. When the balloon 200 with the mounting fixture is accommodated in the container 300, the front ends of the pair of guide pieces 108a, 108b are preferably arranged along the short axis direction D of the ellipse of the small groove 306 ( Fig.10 ) In addition, “the guide pieces are arranged along the short axis direction” means that a pair of guide pieces are arranged on both sides of the short axis of the small groove portion 306 .

[0077] The wing 112 of the balloon mounting jig 100 is accommodated in the recess 310. The recess 310 has a positioning surface 310a formed in a direction perpendicular to the insertion direction B of the balloon mounting jig 100 and a first limiting surface 310b formed in the circumferential direction of the body portion. The contact between the positioning surface 310a and the wing 112 of the balloon mounting jig 100 determines the position in the direction perpendicular to the insertion direction B of the balloon mounting jig 100, and the balloon body 60C can be prevented from contacting the side of the body portion 302, thereby stabilizing the shape of the balloon.

[0078] Furthermore, the first limiting surface 310b also limits the rotation direction of the insertion direction B of the balloon mounting jig 100 relative to the central axis by contacting the wing portion 112. Thus, the balloon 200 with the mounting jig can be prevented from rotating during transportation, and the balloon bodies 60C arranged around the balloon mounting jig 100 can be prevented from sticking to each other, thereby maintaining the shape of the balloon bodies 60C.

[0079] The flange portion 312 is formed by expanding from the container opening portion 308 in a direction perpendicular to the insertion direction B of the balloon mounting jig 100. The flange portion 312 is composed of an outer peripheral portion 312a and an inner peripheral portion 312b, and the inner peripheral portion 312b and the outer peripheral portion 312a are provided in order from the container opening portion 308 side. The inner peripheral portion 312b is formed on the bottom 304 side of the outer peripheral portion 312a in the insertion direction B of the balloon mounting jig 100. That is, the outer peripheral portion 312a and the inner peripheral portion 312b are formed in a stepped shape, and the outer peripheral portion 312a is formed to protrude in the direction opposite to the bottom 304 side.

[0080] The cover 314 is attached to the flange 312 and seals the interior of the container 300 to ensure sterility. The cover 314 is attached to an attached surface provided on the base end side of the outer peripheral portion 312a of the flange 312. By attaching the cover 314 to the outer peripheral portion 312a, the area to which the cover 314 is attached can be reduced.

[0081] [Balloon installation method]

[0082] Next, use Figures 11 to 18 The balloon installation method is described.

[0083] The package of the balloon with the mounting jig is prepared, and the cover portion 314 is removed. Fig.11 This is a diagram of the insertion portion of the endoscope being inserted into the package of the balloon with the mounting clamp removed from the cover. Fig.12 As shown, in the package of the balloon with the mounting jig with the cover 314 removed, the first opening 104 side of the balloon mounting jig 100 is arranged on the container opening 308 side of the storage container 300. In this state, the insertion portion 12 of the endoscope 10 is inserted from the first opening 104. The insertion portion 12 is inserted until it abuts against the small groove 306 of the storage container 300.

[0084] Fig.12 108a and 108b. Figure 6 As shown, in the balloon 200 with the mounting fixture, the first barrel 60A and the second barrel 60B are arranged outside a pair of guide pieces 108a, 108b. Therefore, by inserting the insertion portion 12 between the pair of guide pieces 108a, 108b, the insertion portion 12 can be inserted into the interior of the first barrel 60A and the second barrel 60B via the pair of guide pieces 108a, 108b.

[0085] And, if Fig.10As shown, in a state where the balloon 200 with the mounting fixture is accommodated in the storage container 300, the front ends of the pair of guide pieces 108a and 108b are arranged along the short axis direction D of the elliptical shape of the small groove portion 306. If the insertion portion 12 is inserted into the first barrel portion 60A via the pair of guide pieces 108a and 108b, the insertion portion 12 contacts the first barrel portion 60A in the short axis direction D of the small groove portion 306. And, it is clamped in the short axis direction D of the small groove portion 306. In the long axis direction E of the small groove portion 306, the insertion portion 12 contacts the pair of guide pieces 108a and 108b, so that the insertion portion 12 can be easily moved compared to the case of contacting with the first barrel portion 60A. In addition, in the long axis direction E, there is a space 316 on the opposite side across the first barrel portion 60A of the inserted insertion portion 12. Thus, the insertion portion inserted into the first tube portion 60A is fixed in the short axis direction D of the small groove portion 306 , and the insertion portion 12 can be moved in the long axis direction E. Therefore, by inserting the insertion portion 12 while moving it in the long axis direction, the insertion portion 12 can be inserted to the front end of the small groove portion 306 .

[0086] Furthermore, in the balloon 200 with the mounting jig, it is preferred that the front end of the insertion portion 12 is accommodated in the storage container 300 in a state where the front end of the pair of guide pieces 108a, 108b protrudes from the front end of the first tube 60A by about 0.5 to 3 mm, taking into account the size of the front end of the insertion portion 12 protruding from the front end when the insertion portion 12 is mounted on the balloon. By inserting the front end of the insertion portion 12 until it abuts against the front end of the small groove 306 while the pair of guide pieces 108a, 108b are in contact with the front end of the small groove 306, the end of the first tube 60A can be aligned with the front end of the insertion portion 12.

[0087] Then, if Fig.13 As shown, the balloon 200 with the mounting jig inserted into the insertion portion 12 is pulled out from the storage container 300. In addition, in the pulled balloon 200 with the mounting jig and the endoscope 10, when the positions of the front end of the insertion portion 12 and the end of the first tube 60A of the balloon 60 are inconsistent, the balloon mounting jig 100 is moved along the longitudinal axis direction of the insertion portion 12 to make the positions of the front end of the insertion portion 12 and the end of the first tube 60A of the balloon 60 consistent. When the balloon 200 with the mounting jig and the endoscope 10 are pulled out, when the positions of the front end of the insertion portion 12 and the end of the first tube 60A of the balloon 60 are consistent, this process may not be performed.

[0088] Next, the portion where the insertion section 12 contacts the first tube section 60A is pressed. Specifically, the first tube section 60A is pressed toward the insertion section 12 while avoiding the pair of guide pieces 108a and 108b of the insertion section 12. Fig.14As shown, the balloon mounting jig 100 is moved toward the base end side of the insertion portion 12. By moving the balloon mounting jig 100 while pressing the first barrel 60A, the position of the first barrel 60A can be fixed and the position of the second barrel 60B can be moved together with the balloon mounting jig 100. Fig.15 As shown, the second tube portion 60B is moved outward from the folded opening 66, and the second tube portion 60B is moved to a position where the balloon is mounted in a length.

[0089] The balloon installation length can be adjusted by using the flange portion 312 of the container 300. The length L2 from one end to the other end of the flange portion 312 is set equal to the balloon installation length (refer to Figure 7 ). The "balloon installation length" refers to the length from the end of the first barrel 60A to the end of the second barrel 60B when the balloon 60 is installed in the insertion portion 12 of the endoscope 10. By setting the length L2 of the flange portion 312 equal to the balloon installation length, the balloon 60 installed in the insertion portion 12 can be used as a reference for adjusting to an appropriate length, so that the length of the balloon 60 can be easily adjusted.

[0090] Then, if Fig.16 As shown, pay attention to not moving the position of the balloon 60, and roll the second barrel 60B toward the first barrel 60A side until the pair of guide pieces 108a, 108b are detached. If the second barrel 60B is rolled until the pair of guide pieces 108a, 108b are detached, the balloon mounting jig 100 is removed. The balloon mounting jig 100 opens the first opening 104 and the second opening 106 of the main body 102, and the balloon mounting jig 100 is pulled out by moving the balloon mounting jig 100 toward the insertion portion 12 along the front end direction. When the balloon mounting jig 100 is formed of paper, the balloon mounting jig 100 can be torn and removed.

[0091] When the balloon mounting jig 100 is removed, the balloon 60 is fixed in position to prevent it from moving, and the second tube 60B is rolled back to its original state ( Fig.17 ). Then, if Fig.18 As shown, the position of the second tube portion 60B is finally adjusted to a balloon mounting length using the flange portion 312 of the storage container 300 , and the balloon 60 is mounted on the insertion portion 12 .

[0092] Finally, the first balloon fixing member 61 and the second balloon fixing member 62 are inserted into the first tube portion 60A and the second tube portion 60B of the balloon 60 to fix the balloon 60 to the insertion portion 12 (see FIG. Figure 2). Rubber bands can be used as the first balloon fixing member 61 and the second balloon fixing member 62. The rubber bands can be installed using, for example, a device described in Japanese Patent Application Laid-Open No. 2013-126526. In addition, wires can be used as the first balloon fixing member 61 and the second balloon fixing member 62, and the balloon 60 can be fixed to the insertion portion 12 by winding the wires around the first tube 60A and the second tube 60B.

[0093] <Modification of the container>

[0094] Fig.19 is a perspective view of a storage container according to a modified example. Fig. 20 It is a cross-sectional view of a balloon with a mounting fixture contained in a container.

[0095] The trunk 402 of the container 400 of the modified example includes a trunk body 418 provided on one side of the container opening 308, a middle groove 420 provided on one side of the small groove 306 and having a width narrower than the trunk body 418, and a step 422 provided between the trunk body 418 and the middle groove 420. Fig.19 In the illustrated receiving container 400 , the step portion 422 has a surface in a direction perpendicular to the insertion direction of the insertion portion 12 .

[0096] The main body 102 of the balloon mounting jig 100 is accommodated in the trunk body 418 of the storage container 400. The pair of guide pieces 108a and 108b of the balloon mounting jig are accommodated in the small groove 306 and the middle groove 420. With such a structure, in the state where the balloon mounting jig 100 is accommodated, the end of the main body 102 of the balloon mounting jig 100 located on the side of the pair of guide pieces 108a and 108b can be arranged at the junction of the trunk body 418 and the middle groove 420. That is, the step portion 422 provided between the trunk body 418 and the middle groove 420 of the storage container 400 and the end of the main body 102 of the balloon mounting jig 100 located on the side of the pair of guide pieces 108a and 108b are formed on the same surface in a direction perpendicular to the insertion direction of the insertion portion 12 of the endoscope 10. According to this structure, the step portion 422 becomes the second limiting surface 424 for limiting the position of the main body 102 of the balloon mounting fixture 100 in the insertion direction. The second limiting surface 424 contacts the end of the main body 102 of the balloon mounting fixture 100, which is the restricted portion 116, and is located on one side of a pair of guide pieces 108a, 108b, so that the position of the balloon mounting fixture 100 in the insertion direction can be limited.

[0097] like Figure 3-Figure 5As shown, bending portions 110a, 110b, and 110c are provided on the side portions in the width direction of the main body 102 of the balloon mounting fixture 100, and the main body 102 can be folded into a flat shape by bending it inward. Since the bending portions 110a, 110b, and 110c are formed along the insertion direction of the insertion portion 12 of the endoscope 10, the buckling strength when a force is applied in the insertion direction can be increased. In a state where the balloon mounting fixture 100 is accommodated, the position of the second limiting surface 424 is provided in the width direction of a pair of guide pieces 108a and 108b. By contacting the second limiting surface 424 at the position of the bending portions 110a, 110b, and 110c of the main body 102, the main body 102 can be prevented from buckling in the insertion direction. Therefore, when the insertion part 12 is inserted, it is possible to prevent the pair of guide pieces 108a, 108b from being subjected to force, thereby preventing the pair of guide pieces 108a, 108b from being bent. Accordingly, the insertion part 12 can be stably inserted into the first tube 60A of the balloon 60 and the front end of the pair of guide pieces 108a, 108b.

[0098] In addition, since the pair of guide pieces 108a and 108b can be prevented from bending, the buckling strength of the pair of guide pieces 108a and 108b can be made smaller than the buckling strength of the main body 102. Accordingly, the thickness of the pair of guide pieces 108a and 108b can be reduced. By reducing the thickness of the pair of guide pieces 108a and 108b, the effect of the pulling force of the balloon 60 on the balloon installation jig 100 can be reduced, and not only is it easy to operate when the balloon installation jig 100 is removed from the balloon 60, but the balloon installation jig 100 can also be integrated with the balloon 60 and easily moved on the insertion portion 12, thereby facilitating the balloon installation operation.

[0099] Fig.21 This is a diagram of a modified example in which an insertion portion is inserted into a balloon mounting fixture contained in a storage container. When the balloon mounting fixture 100 is inserted into the insertion portion 12 of the endoscope 10 from the first opening 104 along a pair of guide pieces 108a, 108b, the balloon mounting fixture 100 is subjected to insertion resistance due to the influence of the pulling force of the first tube 60A and the second tube 60B of the balloon 60, and a force is applied to the insertion direction of the insertion portion 12 by the balloon mounting fixture 100. In the storage container 400, the step portion 422 and the restricted portion 116 of the balloon mounting fixture 100 are in contact, and the balloon mounting fixture 100 can be prevented from moving in the insertion direction of the insertion portion 12. Thus, it is possible to prevent the pair of guide pieces 108a, 108b from being applied with force in the insertion direction of the insertion portion 12, and it is possible to prevent the pair of guide pieces 108a, 108b from being bent. Accordingly, the insertion portion 12 can be easily inserted into the front end of the first tube 60A of the balloon 60.

[0100] [Shape of a pair of guide pieces]

[0101] Next, the preferred shapes of the pair of guide pieces 108a and 108b are described. Figure 3 As shown, a pair of guide pieces 108a, 108b has a front end portion provided at the front end side of the guide pieces 108a, 108b, and one end portion of the width direction of the guide pieces 108a, 108b has an inclined portion 114 formed obliquely relative to the length direction A. The inclined portion 114 is formed in a manner that the width of the guide pieces 108a, 108b narrows linearly toward the front end side. Thus, the guide pieces 108a, 108b can be easily inserted into the first barrel 60A and the second barrel 60B of the balloon 60. By providing the inclined portion 114, the area where the insertion portion 12 contacts the first barrel 60A when the insertion portion 12 is inserted into the first barrel 60A via the pair of guide pieces 108a, 108b can be expanded. Thus, by pressing the area where the insertion portion 12 contacts the first barrel 60A with a finger, the balloon mounting fixture 100 can be easily pulled out from the first barrel 60A.

[0102] The inclined portion 114 is provided on each of the pair of guide pieces 108a and 108b. The position of the inclined portion 114 is provided at a position symmetrical with respect to the central axis of the main body 102. That is, when the pair of guide pieces 108a and 108b are observed from any side of the guide pieces 108a and 108b, the inclined portion 114 is provided at a position where they do not overlap. By providing the position symmetrical with respect to the central axis of the main body 102, the first cylinder 60A can be pressed from both sides in the width direction of the insertion portion 12, so that the balloon mounting fixture 100 can be easily pulled out.

[0103] Furthermore, by providing the inclined portion 114, the contact area between the pair of guide pieces 108a, 108b and the first barrel portion 60A can be reduced. By reducing the contact area between the pair of guide pieces 108a, 108b and the first barrel portion 60A, when the insertion portion 12 is inserted, the contact area between the insertion portion 12 and the first barrel portion 60A and the second barrel portion 60B becomes larger. Therefore, the insertion portion 12 becomes difficult to insert. On the other hand, when the guide pieces 108a, 108b are pulled out, the first barrel portion 60A can be pressed against the insertion portion 12, so that the guide pieces 108a, 108b can be easily pulled out.

[0104] On the contrary, if the contact area between the pair of guide pieces 108a, 108b and the first barrel 60A is large when the insertion portion 12 of the endoscope 10 is inserted, the insertion portion 12 can be inserted between the guide pieces 108a, 108b, so that the insertion can be easily performed. However, when the guide pieces 108a, 108b are pulled out from the first barrel 60A, the area pressing the first barrel 60A and the insertion portion 12 becomes small, so it becomes difficult to pull out the guide pieces 108a, 108b.

[0105] In order to take into account both the ease of insertion of the insertion portion 12 and the ease of removal of the pair of guide pieces 108a, 108b, it is preferred that the pair of guide pieces 108a, 108b have a contact surface having a contact area with the insertion portion 12 of 55% or more and 70% or less when the insertion portion 12 is inserted. The following is a table comparing the ease of insertion of the insertion portion 12 with respect to the contact area between the insertion portion 12 and the pair of guide pieces 108a, 108b and the ease of removal of the balloon mounting jig 100 when the area of ​​the pair of guide pieces 108a, 108b is changed. In addition, the evaluation was performed according to the following criteria.

[0106] [Ease of insertion]

[0107] A: It can be inserted without any problem.

[0108] B: Although it can be inserted, the endoscope needs to be pressed hard.

[0109] C: Although the balloon can be inserted, the tip of the balloon may be misaligned.

[0110] 〔Easy to remove〕

[0111] A: It can be pulled out without any problem.

[0112] B: Although it can be pulled out, the balloon needs to be pressed hard.

[0113] C: Although the balloon can be removed, the tip of the balloon may be displaced.

[0114] [Table 1]

[0115] Contact area (%) Easy insertion Easy to remove 80 A C 75 A C 70 A B 65 A A 60 B A 55 B A 50 C A 45 C A 40 C A

[0116] As shown in Table 1, by setting the contact area to 55% or more and 70% or less, it is possible to achieve both easy insertion of the insertion portion 12 and easy removal of the guide pieces 108a and 108b.

[0117] As described above, according to the present embodiment, the insertion portion 12 of the endoscope 10 can be inserted into the first barrel portion 60A and the second barrel portion 60B via the pair of guide pieces 108a and 108b by inserting the insertion portion 12 of the endoscope 10 from the first opening 104 of the balloon mounting jig 100. Then, the balloon 60, the balloon mounting jig 100, and the endoscope 10 are taken out of the storage container 300, the second barrel portion 60B is moved together with the balloon mounting jig 100, and the position of the balloon 60 mounted on the endoscope 10 is adjusted, thereby making it possible to easily mount the balloon 60 on the endoscope 10.
