[Brief explanation of the drawing]

[0013] [Figure 1] This is a plan view of a cardboard sheet having an assembly area formed therein for assembling a ligation training tool for a ligation training kit according to one embodiment of the present invention. [Figure 2] Figure 1 is a perspective view of a ligation training device assembled from cardboard sheets. [Figure 3] Figure 2 is a perspective view showing a ligation training session using the ligation training device. [Modes for carrying out the invention]

[0014] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the surface side of a cardboard sheet 2 of a ligation training kit 1 according to one embodiment of the present invention. The ligation training kit 1 includes a cardboard sheet 2 and a rubber band 3, which have an assembly area formed therein for assembling a ligation training tool. Figure 2 shows the ligation training tool assembled by the assembly area of ​​this cardboard sheet 2. The cardboard sheet 2 is made of cardboard such as corrugated cardboard having a grain direction 4.

[0015] As shown in Figure 1, the assembly area of ​​the cardboard sheet 2 includes a cylindrical portion forming area 6 for forming a hollow cylindrical portion 5 (see Figure 2) with a polygonal cross-section (in this embodiment, a regular hexagon) for training deep ligation. The cylindrical portion forming area 6 has a rectangular shape with a first long side 7 on the side forming the bottom surface of the cylindrical portion 5, a second long side 8 on the opposite side, and a first short side 9 and a second short side 10.

[0016] Furthermore, the cylindrical portion forming region 6 comprises a side forming region 12 divided into rectangular regions equal to the number of corners of the polygonal cylindrical portion 5 by a plurality of first lines 11 parallel to the first and second short sides 9 and 10, and a splice region 15 connected to the first rectangular region 13 to which the first short side 9 belongs via a second line 14. The splice region 15 is a splice region 17 (see Figure 2) that overlaps with the second rectangular region 16 to which the second short side 10 belongs, and connects the first rectangular region 13 to the second rectangular region 16.

[0017] One of the three third rectangular regions 18, which is the number of rectangular regions mentioned above, is connected to the cardboard sheet 2 on the first long side 7 via a third scribed line 19. In this embodiment, the third scribed line 19 is composed of a lead scribe, which is a perforated scribed line. The area around the cylindrical portion forming region 6, other than the third scribed line 19, is separated from the cardboard sheet 2 by a cutting line 20.

[0018] In the cylindrical portion forming region 6, slits 21 are provided for stretching a rubber band 3 over the space between any two opposing first score lines 11 within the cylindrical portion 5 from the outside of the cylindrical portion 5. Three slits 21 are provided so as not to cut the two first score lines 11. Each slit 21 is positioned closer to the first long side 7 than to the second long side 8, and is parallel to the first and second long sides 7 and 8.

[0019] The cylindrical portion forming region 6 protrudes from a position on the second short side 10 that is closer to the second long side 8 than the slit 21, and includes a tab region 23 that serves as a connecting tab 22 (see Figure 2) for connecting the second rectangular region 16 to the first rectangular region 13. The cylindrical portion forming region 6 is provided with a tab insertion hole 24 corresponding to the tab region 23, into which the connecting tab 22 is inserted, along the second grid line 14.

[0020] In addition, the assembly area for assembling the ligation training tool includes a fixing portion forming area 26 for forming a cylindrical portion fixing portion 25 (see FIG. 2) for fixing the cylindrical portion 5 to the cardboard sheet 2. The fixing portion forming area 26 includes a rectangular area 29 partitioned into three areas by two mutually parallel fourth and fifth ruled lines 27, 28, and a protruding area 31 that protrudes from the edge of the fourth ruled line 27 of the rectangular area 29 and serves as a protruding tab 30.

[0021] The rectangular area 29 is connected to the cardboard sheet 2 via a sixth ruled line 32 at the edge on the side of the fifth ruled line 28. The periphery of the fixing portion forming area 26 other than the portion connected to the cardboard sheet 2 via the sixth ruled line 32 is separated from the cardboard sheet 2 by a cutting line 20.

[0022] In the rectangular area 29, there are provided a protruding tab insertion hole 33 for forming the cylindrical portion fixing portion 25 by inserting the protruding tab 30 adjacent along the sixth ruled line 32, and a slit-shaped insertion fixing hole 34 extending from the edge on the side of the sixth ruled line 32 to the fifth ruled line 28. The bottom end portions of the second rectangular area 16 of the cylindrical portion forming area 6 and the overlapping flange area 15 are inserted into and fixed to the insertion fixing hole 34.

[0023] In addition, the assembly area for assembling the ligation training tool includes two rubber band support portion forming areas 36 for forming two rubber band support portions 35 (see FIG. 2) that respectively support a rubber band 3 stretched between two locations for use in training ligation techniques.

[0024] Each rubber band support portion forming area 36 is a rectangular area having a long side and a short side, and includes two side areas 37 on both sides in the direction along the long side, and an intermediate area 40 located between the two side areas 并 connected to the two side areas 37 via seventh and eighth ruled lines 38, 39 respectively.

[0025] The intermediate region 40 is connected to the cardboard sheet 2 via the ninth scribe line 41 on one of the longer sides of the rubber band support region 36. The periphery of each rubber band support region 36 is separated from the cardboard sheet 2 by the cutting line 20, except for the portion connected to the cardboard sheet 2 via the ninth scribe line 41.

[0026] In each rubber band support area 36, ​​a notch-forming area 43 is provided, separated by a cutting line, in the middle of the 7th and 8th scribed lines 38 and 39, respectively, to serve as a notch 42 (see Figure 2) for fixing the rubber band 3. In the cardboard sheet 2, the two rubber band support areas 36 are arranged so that the sides of the 9th scribed line 41 face each other.

[0027] In this configuration, to assemble the ligation training tool with the cylindrical part 5, for example, first, the cylindrical part forming region 6 is folded along each of the first scribe lines 11 to form a regular hexagon. Then, the splice region 15 is folded along the second scribe line 14 and overlapped inside the second rectangular region 16, and the tab region 23 is inserted into the tab insertion hole 24 and fixed in place. As a result, the cylindrical part forming region 6 takes on a hexagonal shape, and the cylindrical part 5 is formed in a state where it is lying down relative to the cardboard sheet 2.

[0028] Next, the fixing portion forming region 26 is folded along the fourth scribe line 27, the fifth scribe line 28, and the sixth scribe line 32 to form a triangular prism shape, and the protruding region 31 is inserted into the protruding tab insertion hole 33 and fixed. This forms a cylindrical portion fixing portion 25 (see Figure 2) for fixing the aforementioned fallen cylindrical portion 5 upright to the cardboard sheet 2. At this time, the cylindrical portion fixing portion 25 forms an insertion fixing portion 25a (see Figure 2) which is formed when the insertion fixing hole 34 of the fixing portion forming region 26 is folded on both sides of the fifth scribe line 28.

[0029] Next, the aforementioned fallen cylindrical portion 5 is folded along the third ruled line 19 to stand it upright and fixed to the cardboard sheet 2 by the cylindrical portion fixing portion 25. During this fixing, the connection portion of the cylindrical portion 5 corresponding to the first long side 7 side of the second rectangular region 16, where the joint area 15 of the cylindrical portion forming region 6 is overlapped, is fixed to the cardboard sheet 2.

[0030] In other words, this fixing is performed by straightening the fallen cylindrical portion 5 and further bending the cylindrical portion fixing portion 25 along the sixth scribed line 32, while inserting the connecting portion of the cylindrical portion 5 into the insertion fixing portion 25a (see Figure 2) of the cylindrical portion fixing portion 25. When this fixing is completed, the side of the cylindrical portion fixing portion 25 on the protruding region 31 side is in contact with the cardboard sheet 2.

[0031] As a result, as shown in Figure 2, the cylindrical part 5 is fixed to the cardboard sheet 2 in an upright position via the cylindrical part fixing part 25. The rubber band 3 is placed over the cylindrical part 5 fixed to the cardboard sheet 2 from the outside and passed through the slit 21, and the rubber band 3 is stretched across the space between the two first scribed lines 11b. This completes the assembly of the ligation training tool with a hollow cylindrical part 5 for training deep ligation.

[0032] On the other hand, in order to form a ligation training tool with two rubber band support parts 35 (see Figure 2), first, both side regions 37 of one of the rubber band support part forming regions 36 are folded approximately 90° toward the surface side of the cardboard sheet 2 along the 7th scribed line 38 and the 8th scribed line 39, respectively. Next, the middle region 40 of the rubber band support part forming region 36 is folded approximately 90° along the 9th scribed line 41.

[0033] Furthermore, the notched portion 43 is removed from the cardboard sheet 2 to form a notch 42 (see Figure 2). This completes the formation of one of the rubber band support portions 35. The other rubber band support portion 35 is then formed by performing the same process on the other rubber band support portion forming region 36. The rubber band 3 is then placed over both formed rubber band support portions 35. The position of the placed rubber band 3 is determined by the notches 42 in both rubber band support portions 35. This completes the assembly of the ligation training tool using the two rubber band support portions 35.

[0034] Figure 3 shows how ligation training is performed using a ligation training device with two rubber band support parts 35. As shown in Figure 3, the rubber band 3 placed between the two rubber band support parts 35 simulates an incision. Ligament training is performed on this simulated incision using a simulated ligament thread 44. Ligament training using a ligation training device with a tubular part 5 is performed in the same manner.

[0035] As described above, according to this embodiment, since the kit includes a cardboard sheet 2 with an assembly area formed therein for assembling the ligation training tool, it is easy to carry and the ligation training tool can be assembled and ligation training performed at any time and place. Furthermore, the ligation training kit 1 can be disposable as needed.

[0036] Furthermore, the assembly area for assembling the ligation training device includes a cylindrical part forming area 6 for forming a hollow cylindrical part 5 for training deep ligation, so that the ligation training device with the cylindrical part 5 for training deep ligation can be easily assembled.

[0037] Furthermore, the cylindrical portion forming region 6 includes a tab region 23 that protrudes from a position on the second short side 10 that is closer to the second long side 8 than the slit 21, and the cylindrical portion forming region 6 is provided with a tab insertion hole 24 corresponding to the tab region 23, so that a ligation training tool suitable for deep ligation training using the cylindrical portion 5 can be assembled more easily.

[0038] Furthermore, the assembly area for assembling the ligation training device includes a fixing area 26 for fixing the cylindrical part 5 to the cardboard sheet 2, so that the formed cylindrical part 5 can be easily fixed to the cardboard sheet 2.

[0039] Furthermore, since the assembly area includes two rubber band support area 36, ​​the rubber band 3 stretched across the two rubber band support areas 35 formed by these areas can be used to simulate an incision site, allowing for training in ligation techniques on the simulated incision site.

[0040] It should be noted that the present invention is not limited to the embodiments described above. For example, the ligation training kit 1 may include rubber bands 3 and dummy ligating threads 44. [Explanation of Symbols]
