  The inner diameters of the balloon tube portions 210 and 220 are smaller than the outer diameter of the insertion portion 100 of the endoscope. Therefore, as shown in FIG. 1, when the insertion portion 100 of the endoscope is inserted into each balloon tube portion 210, 220, the balloon 200 is inserted into the insertion portion 100 of the endoscope by the elastic force of each balloon tube portion 210, 220. It is fixed substantially tightly.

  FIG. 2 is a perspective view of the balloon mounting jig 300 of the present embodiment. FIG. 3 is a perspective view of a paper tube for constituting the balloon mounting jig 300.

  The balloon attachment jig 300 is a jig for attaching the balloon 200 to the insertion portion 100 of the endoscope. As shown in FIG. 3A, four broken lines L1 to L4 are formed in advance ( For example, a sheet S (for example, a sheet having a predetermined rigidity such as Kent paper) in which a concave line or a perforated line is formed) is one broken line L1, and A paper tube in a state in which the inner peripheral surfaces are overlapped is formed by folding it in half along the other fold line L2 and adhering as shown in FIG. 3 (b), and this paper tube is shown in FIG. 3 (c) ( As shown in d), it is formed by press punching into a substantially H shape.

  As shown in FIG. 3D, the press-punched balloon mounting jig 300 is folded in two along the first ring piece 311 and the other fold line L2 in a state of being folded in two along one fold line L1. Of the ring body 310 having the second ring piece 312 in the closed state, the first guide piece 331 in a state of being continuous with one end of the edge of the ring body 310 and being folded in two along one fold line L1. The second guide piece 332 that is continuous with the other end of the edge and folded in two along the other fold line L2, and the edge opposite to the edge where the first guide piece 331 of the ring body 310 is continuous The first introduction piece 321 that is continuous to one end and folded in two along one fold line L1, and the edge on the opposite side to the edge where the second guide piece 332 of the ring body 310 is continuous 1st continuous to the end And it is extended from Irihen 321 and a second introduction member 322 in a state of being folded in two along the other polygonal line L2.

  As shown in FIG. 3 (d), since the polygonal lines L3 and L4 are formed in advance in the portion corresponding to the boundary between the first ring piece 311 and the second ring piece 312, as shown in FIG. It is possible to easily and accurately bend the first ring piece 311 and the second ring piece 312 along the fold lines L3 and L4 so that the outer side becomes a peak.

  Further, by folding along the previously formed folding lines L3 and L4, the first and second ring pieces 311 and 312 in a folded state (and the first and second guide pieces 331 and 332, and The first and second introduction pieces 321 and 322) are returned to the flat state before being folded in two as shown in FIG. 2, and the first ring piece 311 and the second ring piece 312 (further, the first guide piece). 331 and the second guide piece 332, the first introduction piece 321 and the second introduction piece 322, and two broken lines L1 and L2) extending in the axial direction can be easily and accurately overlapped. In this way, it is possible to provide the balloon mounting jig 300 having an appearance that makes it easy to recall the usage state by bending along the previously formed folding lines L3 and L4.

  Further, the inner surfaces (surfaces facing each other) of the first and second ring pieces 311 and 312, the first and second guide pieces 331 and 332, and the first and second introduction pieces 321 and 322 are made of corn starch or the like. Lubricity is imparted by carrying out the step of attaching the lubricant at the time of punching.

  As shown in FIGS. 2 and 3, the ring body 310 is formed at the substantially center of the edge of the first ring piece 311, and at the center of the edge of the second ring piece 312. And a second introduction piece 322 superimposed on the first introduction piece 321.

  The second introduction piece 322 has an extension portion 322a extended from the first introduction piece 321. As shown in FIG. 6, the insertion portion 100 of the endoscope is brought into contact with the extension portion 322a. It can be turned up. The insertion portion 100 of the endoscope is inserted between the second introduction piece 322 and the first introduction piece 321 that are turned up, and then the ring body 310 (between the first ring piece 311 and the second ring piece 312). And then inserted between the first guide piece 331 and the second guide piece 332 provided on the ring body 310 (see FIG. 7), and therefore between the first guide piece 331 and the second guide piece 332 The insertion portion 100 of the endoscope can be easily (smoothly and quickly) inserted into the endoscope.

  As shown in FIG. 6, the width H1 of the first and second introduction pieces 321, 322 is longer than the diameter H2 of the insertion portion 100 of the endoscope. Therefore, the insertion portion 100 of the endoscope is easily brought into contact with the extension portion 322a (that is, even when the extension portion 322a is aimed roughly). Further, the width H1 of the first and second introduction pieces 321 and 322 is shorter than the width H3 of the ring body 310. Therefore, compared with the case where the width H1 of the first and second introduction pieces 321 and 322 is the same as the width H3 of the ring body 310, the rigidity of the extension portion 322a is weakened, so that the extension portion 322a is turned up with a relatively weak force. Is possible.

  As shown in FIGS. 2 and 3, the ring body 310 includes a first guide piece 331 formed substantially at the center of the edge of the first ring piece 311 opposite to the edge where the first introduction piece 321 is formed. And a second guide piece 332 that is formed in the approximate center of the edge opposite to the edge of the second ring piece 312 on which the second introduction piece 322 is formed and is superimposed on the first guide piece 331. ing.

  As shown in FIG. 2, the edge 313 of the ring body 310 adjacent to the first and second guide pieces 331 and 332 has a length H4 (e.g., a finger that can be hung by an operator such as an operator). Thickness). That is, the edge portion 313 functions as a finger hook portion.

  The first and second guide pieces 331 and 332 are superimposed on each other as shown in FIG. 2, and are folded into two along the center line A3 as shown in FIG. Inserted. Since the first and second guide pieces 331 and 332 are folded in two and inserted into the balloon tube portion 210 in a state where the width H6 is shorter than the inner diameter H7 of the balloon tube portion 210 (see FIG. 4), the first and second guide pieces 331 and 332 are inserted. The guide pieces 331 and 332 hardly contact the inner wall of the balloon cylinder part 210, and the first and second guide pieces 331 and 332 can be inserted into the balloon cylinder part 210 very easily (smoothly and quickly). It is possible.

  The first and second guide pieces 331 and 332 (the same applies to the first and second ring pieces 311 and 312 and the first and second introduction pieces 321 and 322) are previously formed with a polygonal line along the center line A3. (For example, a recess is formed along the center line A3, or a perforation is formed along the center line A3). Therefore, the first and second guide pieces 331 and 332 (the first and second ring pieces 311 and 312 and the first and second introduction pieces 321 and 322) are easily folded in two along the center line A3. Is possible.

  As shown in FIG. 2, a taper T is formed at the tips of the first and second guide pieces 331 and 332. Therefore, when the first and second guide pieces 331 and 332 are overlapped and folded along the center line A3, only the tip end side is inclined as shown in FIG. Therefore, it is possible to insert the first and second guide pieces 331 and 332 into the balloon tube portion 210 very easily (smoothly and quickly).

  As shown in FIG. 5, the first and second guide pieces 331 and 332 are returned to the state before being folded in two after being positioned in the balloon tube portion 210.

  In the first and second guide pieces 331 and 332, the width H5 before being folded in half is longer than ½ of the circumferential length (inner diameter H6 × π) of the inner circumference of the balloon cylinder portion 210 in the natural state. (Or substantially the same as ½ of the circumferential length of the inner circumference of one of the cylindrical portions). Accordingly, when the first and second guide pieces 331 and 332 are returned to the original state before being folded in half, the balloon tube portion 210 is pushed and expanded by the first and second guide pieces 331 and 332, and due to its elastic force. The first and second guide pieces 331 and 332 are in close contact with each other.

  Next, an operation of attaching the balloon 200 to the insertion portion 100 of the endoscope using the balloon attachment jig 300 having the above configuration will be described.

  First, as shown in FIG. 2, the first ring piece 311 (the first introduction piece 321 and the first guide piece are also the same as 331) and the second ring piece 312 (the same applies to the second introduction piece 322 and the second guide piece 332). Furthermore, as shown in FIG. 4, it folds in two so that the 1st introduction piece 321 may become an outer side along the centerline A3 (the folding lines L1 and L2 mutually overlap | superposed). The first and second ring pieces 311 and 312 (the first and second introduction pieces 321 and 322, the first and second guide pieces 331 and 332 are also the same) are preliminarily bent along the center line A3 with the fold lines L1 and L2 (mutually Since the overlapped broken lines L1 and L2) are formed (for example, a recess is formed in advance along the center line, or a perforation is formed in advance along the center line), the center line A3 Can be easily and accurately folded in half.

  Next, as shown in FIG. 4, the first and second guide pieces 331 and 332 folded in half are inserted into the balloon tube portion 210 in the natural state. The first and second guide pieces 331 and 332 are inserted into the balloon cylinder 210 in a state where the folded width H6 is shorter than the inner diameter H7 of the balloon cylinder 210 (see FIG. 4). 2 The guide pieces 331 and 332 hardly contact the inner wall of the balloon cylinder part 210, and the first and second guide pieces 331 and 332 can be inserted into the balloon cylinder part 210 very easily (smoothly and quickly). Is possible.

  Next, as shown in FIG. 5, the first and second guide pieces 331 and 332 positioned in the balloon tube portion 210 are returned to the flat state before being folded in half. The first and second guide pieces 331 and 332 have a flat width H5 before being folded in half from a half of the circumferential length (inner diameter H6 × π) of the inner circumference of the balloon tube portion 210 in the natural state. Is also longer (or substantially the same as ½ of the circumferential length of the inner periphery of the cylinder part 210). Accordingly, when the first and second guide pieces 331 and 332 are returned to the original state before being folded in half, the balloon tube portion 210 is pushed and expanded by the first and second guide pieces 331 and 332, and due to its elastic force. The first and second guide pieces 331 and 332 are in close contact with each other.

  Next, as shown in FIG. 6, the insertion portion 100 of the endoscope is brought into contact with the extended portion 322 a of the second introduction piece 322 and turned up. Thereby, the insertion part 100 of the endoscope is placed between the second introduction piece 322 and the first introduction piece 321 which are turned up, and then the ring body 310 (between the first ring piece 311 and the second ring piece 312). Next, it is possible to insert sequentially between the first guide piece 331 and the second guide piece 332 provided on the ring body 310 (see FIG. 7).

  Here, the balloon attachment jig 300 is folded by press punching a paper tube into a substantially H shape. By this folding, the balloon attachment jig 300 (the first and second ring pieces 311 and 312, the first and second guide pieces 331 and 332, and the first and second introduction pieces 321 and 322) is The insertion portion 100 of the endoscope is placed between the ring piece 311 and the second ring piece 312 (further, between the first guide piece 331 and the second guide piece 332 and between the first introduction piece 321 and the second introduction piece 322). It tries to bend in the direction that forms the space to be passed. That is, the balloon attachment jig 300 tends to bend along the fold lines L1 and L2 so that the outside becomes a mountain portion as shown in FIG. Thereby, the insertion part 100 of the endoscope is placed between the balloon attachment jigs 300 (between the first ring piece 311 and the second ring piece 312, between the first guide piece 331 and the second guide piece 332, and It can be easily inserted between the first introduction piece 321 and the second introduction piece 322.

  Further, since lubricity is imparted to the inner side surfaces of the first and second ring pieces 311 and 312 by corn starch or the like, the insertion portion 100 of the endoscope and the first and second ring pieces 311 and 312 etc. The frictional resistance between is small. Therefore, the insertion portion 100 of the endoscope is placed between the balloon attachment jig 300 (between the first ring piece 311 and the second ring piece 312, between the first guide piece 331 and the second guide piece 332, and 1 between the introduction piece 321 and the second introduction piece 322).

  At the time of this insertion, the operator's finger such as an operator can be hung on the edge 313 (finger holding portion; see FIG. 2) of the ring body 310 adjacent to the first and second guide pieces 331 and 332. The attachment of the balloon 200 to the insertion portion 100 of the endoscope and the removal of the main attachment jig after the attachment can be performed very easily (smoothly and quickly).

  As shown in FIG. 6, the width H1 of the first and second introduction pieces 321 and 322 is longer than the diameter H2 of the insertion portion 100 of the endoscope. Therefore, the insertion portion 100 of the endoscope is easily brought into contact with the extension portion 322a (that is, even when the extension portion 322a is aimed roughly). Further, the width H1 of the first and second introduction pieces 321 and 322 is shorter than the width H3 of the ring body 310. Therefore, compared with the case where the width H1 of the first and second introduction pieces 321 and 322 is the same as the width H3 of the ring body 310, the rigidity of the extension portion 322a is weakened, so that the extension portion 322a is turned up with a relatively weak force. Is possible.

  The first and second guide pieces 331 and 332 are formed by a sheet S having a smaller coefficient of friction than the balloon tube portion 210. Further, as shown in FIG. 8, the first and second guide pieces 331 and 332 are bent along the center line A3 and are in line contact with the outer peripheral surface of the insertion portion 100 of the endoscope. Further, as shown in FIG. 7 and FIG. 8, in a state where the insertion portion 100 of the endoscope is inserted between the first guide piece 331 and the second guide piece 332 (that is, the balloon tube portion 210), A space H8 is formed between the insertion portions 100 of the endoscope. Accordingly, the insertion portion 100 of the endoscope is smoothly placed between the first guide piece 331 and the second guide piece 332 (that is, the balloon tube portion 210) (the insertion portion 100 of the endoscope contacts the balloon tube portion 210). It is possible to insert).

  Next, a finger of an operator such as an operator is hung on the finger hook portion 313, and the balloon mounting jig 300 (and the balloon 200) is moved in the direction of the arrow in FIG. 7, for example, at a predetermined mounting position shown in FIG. The mounting jig 300 (and the balloon 200) is positioned. Then, the balloon attachment jig 300 (that is, the first and second guide pieces 331 and 332) is extracted from between the balloon tube part 210 and the insertion part 100 of the endoscope. Thereby, the attachment of the balloon 200 to the insertion portion 100 of the endoscope is completed.

  When the insertion portion 100 of the endoscope is inserted between the first guide piece 331 and the second guide piece 332 as described above, the distance between the first and second guide pieces 331 and 332 (balloon cylinder portion 210). Is further expanded, and the first and second guide pieces 331 and 332 and the balloon cylinder part 210 are more firmly adhered to each other by the elastic force of the balloon cylinder part 210, so that the balloon attachment jig 300 (and the balloon 200) is illustrated. 7, the balloon tube portion 210 does not fall off the first and second guide pieces 331 and 332.

  Thereafter, the first ring piece 311 and the second ring piece 312 are spread apart and the balloon attachment jig 300 is moved in the direction opposite to the arrow in FIG. At that time, since the finger hook portion 313 has a predetermined width of H4 (and the ring body 310 is H3), the first ring piece 311 and the second ring piece 312 are in contact with the balloon 200 when they are spread apart. It has a diameter not to be damaged and can be extracted without damaging the balloon 200. There is no problem as long as the diameter when the first ring piece 311 and the second ring piece 312 are widened in a direction away from each other is small enough not to damage the balloon 200 even if slightly touching the balloon 200.

  As described above, according to the balloon mounting jig manufacturing method of the present embodiment, the paper is in a state where the inner peripheral surfaces are overlapped by being bent along the two fold lines L1 and L2 extending in the axial direction. The balloon mounting jig 300 can be manufactured only by press punching the tube into a substantially H shape. Therefore, the balloon attachment jig 300 can be manufactured very simply.

  Next, a modified example will be described.

  In the above embodiment, the balloon attachment jig 300 is described as a jig for attaching the balloon 200 to the insertion portion 100 of the endoscope, but the present invention is not limited to this. For example, the balloon 200 can be attached to an insertion assisting tool (not shown) for assisting insertion of the insertion portion 100 of the endoscope into the body cavity using the balloon attachment jig 300.

  The above embodiment is merely an example in all respects. The present invention is not construed as being limited to these descriptions. The present invention can be implemented in various other forms without departing from the spirit or main features thereof.
