DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in more detail below based on the following embodiments. However, the present invention is not limited to the following embodiments, and can be implemented with appropriate modifications within the scope of the above and below-described purposes, and all such modifications are included within the technical scope of the present invention. For convenience, component reference numerals may be omitted in the drawings. In such cases, reference should be made to the specification or other drawings. The dimensions of various components in the drawings may differ from their actual dimensions, as priority is given to helping understand the features of the present invention.

[0011] A holding member for a medical instrument according to an embodiment is a holding member for holding a medical instrument having a handle portion and a long portion extending from the distal portion of the handle portion, the holding member having a first sheet extending in the longitudinal direction and a second sheet extending in the longitudinal direction, covering a portion of the first sheet and at least a portion of the long portion, and held by the first sheet, the first sheet having a first base portion and a first fold portion that is folded back at one end side in the longitudinal direction toward the other end side and faces the first base portion, the handle portion is held on the side of the first fold portion opposite the side facing the first base portion, the first base portion has, on the opposite side facing the first fold portion, an opposing portion that faces the first fold portion and a non-opposing portion that does not face the first fold portion, and at least a portion of the long portion is held in the non-opposing portion, the second sheet having a curved portion that is convex toward the side opposite the side of the second sheet facing the first sheet, the curved portion extending in the longitudinal direction.

[0012] As described above, the first sheet holds the second sheet, which has a curved portion that is convex toward the opposite side of the first sheet and extends in the longitudinal direction, making the first sheet less likely to bend in the longitudinal direction. Furthermore, the first folded portion of the first sheet is folded in the longitudinal direction, making the first sheet less likely to bend in the width direction. As a result, the first sheet that holds the handle portion and elongated portion of the medical instrument is less likely to deform in the longitudinal and width directions during packaging, packing, transportation, and removal from a packaging box, etc., making the medical instrument easier to remove.

[0013] Hereinafter, a holding member for a medical device according to a first embodiment will be described with reference to Figs. 1 to 7. Fig. 1 is a plan view of a holding member for a medical device according to the first embodiment. Fig. 2 is a cross-sectional view showing the AA cross section of Fig. 1. Fig. 3 is a perspective view of a first sheet before folding back the first fold-back portion. Fig. 4 is a cross-sectional view showing the BB cross section of Fig. 1. Fig. 5 is an enlarged view of a modified first flap of Fig. 1. Fig. 6 is a cross-sectional view showing the BB cross section of a modified second sheet of Fig. 1. Fig. 7 is a cross-sectional view showing the BB cross section of another modified second sheet of Fig. 1.

[0014] As shown in FIGS. 1 and 2 , the holding member 40 according to the first embodiment has a first sheet 10 extending in the longitudinal direction 10X. The first sheet 10 holds a medical instrument 50A having a handle portion 51 and an elongated portion 52 extending from a distal portion 51b of the handle portion 51. The medical instrument 50A is preferably a treatment catheter, a guiding catheter, or a puncture device. Examples of treatment catheters include balloon catheters, microcatheters, penetration catheters, and ablation catheters. Examples of guiding catheters include catheters into which a treatment catheter can be inserted and which can reach a lesion. Examples of ablation catheters include ablation catheters whose distal end is heated by high-frequency current and which cauterize a part of the heart, an aneurysm, a varicose vein, or the like. Examples of puncture devices include puncture devices that puncture biological tissue, such as the atrial septum. It is preferable that the distal end of the puncture device be heated by high-frequency current. The holding member 40 may also be a so-called mount.

[0015] As shown in FIGS. 1 and 2 , the holding member 40 further includes a second sheet 20 extending in the longitudinal direction 20X, covering a portion of the first sheet 10 and at least a portion of the elongated portion 52, and held by the first sheet 10. As shown in FIG. 4 , the second sheet 20 has a curved portion 20C that is curved so as to be convex toward an opposite side 20U of the second sheet 20 from a side 20L facing the first sheet 10, and as shown in FIGS. 1 and 2 , the curved portion 20C extends in the longitudinal direction 20X. Because the curved portion 20C is convex toward the opposite side 20U and extends in the longitudinal direction 20X, the second sheet 20 is less likely to bend in the longitudinal direction 20X. As a result, the first sheet 10 holding the second sheet 20 is less likely to bend in the longitudinal direction 10X. Furthermore, since the curved portion 20C of the second sheet 20 is convex toward the opposite side 20U from the first sheet 10, external impacts directed from the second sheet 20 toward the first sheet 10 can be absorbed, thereby protecting the elongated portion 52.

[0016] 1 and 3, the first sheet 10 has a first base portion 11 and a first folded portion 12 that is folded back from one end side 10a in the longitudinal direction 10X toward the other end side 10b and faces the first base portion 11. Because the first folded portion 12 of the first sheet 10 is folded back in the longitudinal direction 10X, the first sheet 10 is less likely to bend in the width direction 10Y.

[0017] 2 and 3, the first base portion 11 has, on an opposing side 11U opposing the first folded portion 12, an opposing portion 11F opposing the first folded portion 12 and a non-opposing portion 11N not opposing the first folded portion 12. At least a part of the elongated portion 52 is held in the non-opposing portion 11N. The opposing side 11U refers to the opposing side opposing the first folded portion 12 of the first base portion 11 in a vertical direction 11Z perpendicular to the surface of the flat portion of the first base portion 11.

[0018] As shown in FIGS. 1 and 2, the handle portion 51 is held on the side 12U opposite to the side 12L of the first folded portion 12 facing the first base portion 11. The first folded portion 12 is a portion where the sheet is folded, and folding tends to generate a repulsive force in the height direction. When this repulsive force is large, the handle portion 51 is lifted slightly in the height direction by the first folded portion 12, increasing the gap 52S between the elongated portion 52 extending from the distal portion 51b of the handle portion 51 and the non-facing portion 11N. As a result, the user can easily pinch and remove the elongated portion 52.

[0019] 2, the first folded portion 12 of the first sheet 10 preferably has a curved portion 12C. The curved portion 12C can improve the repulsive force in the height direction of the first folded portion 12. The first folded portion 12 may also have a bent portion.

[0020] 1 and 2, in the holding member 40, the first base portion 11 of the first sheet 10 is a flat portion that is a portion of the first sheet 10 other than the first folded portion 12. The flat portion preferably extends in the longitudinal direction 10X.

[0021] 2 and 3, the first base portion 11 and the first folded portion 12 are preferably formed from the same sheet, which can improve the repulsive force of the first folded portion 12 in the height direction.

[0022] Specifically, the facing portion 11F is a portion that faces the first folded portion 12 of the first base portion 11 when the handle portion 51 is arranged on the first folded portion 12. It is preferable that at least a portion of the facing portion 11F contacts the first folded portion 12. This generates friction and reduces displacement of the first folded portion 12 due to vibration, etc., making it less likely that the handle portion 51 will come off the first folded portion 12 during transportation, etc. It is also more preferable that a portion of the facing portion 11F contacts the first folded portion 12, while the other portion of the facing portion 11F does not. The portion that is not in contact with the facing portion 11F is more likely to absorb impacts in the vertical direction 11Z, etc.

[0023] 1 and 2, in the holding member 40, the non-facing portion 11N is a portion on the opposing side 11U of the first base portion 11 that does not face the first folded-back portion 12. The second sheet 20 is preferably held by the non-facing portion 11N. This makes it easier for the second sheet 20 to protect the elongated portion 52, at least a portion of which is held by the non-facing portion 11N.

[0024] The non-facing portion 11N of the first base portion 11 preferably has at least one first flap 1F that holds the second sheet 20. The first flap 1F enables the non-facing portion 11N to hold the second sheet 20.

[0025] As shown in FIG. 1, at least one first flap 1F preferably includes a first-side flap 1Fa that stands from one side 10Ya to the other side 10Yb in the width direction 10Y of the first sheet 10 and is located on the one side 10Ya, and a second-side flap 1Fb that stands from the other side 10Yb to the one side 10Ya and is located on the other side 10Yb. This makes it easier for the non-facing portion 11N to hold the second sheet 20. Furthermore, this makes it easier for tension from the second sheet 20 to be applied to the first sheet 10 in the width direction 10Y, making it difficult for the non-facing portion 11N to bend. It is preferable that there are multiple first-side flaps 1Fa and multiple second-side flaps 1Fb, but there may be only one of each.

[0026] 1, it is preferable that the one-side flap 1Fa and the other-side flap 1Fb face each other in the width direction 10Y. This makes it easier for tension to be applied from the second sheet 20 to the first sheet 10 in the width direction 10Y, making the non-facing portion 11N even more difficult to bend.

[0027] 1 and 4, at least one first flap 1F preferably contacts a surface 20U of the second sheet 20 opposite to the side 20L facing the first sheet 10. This allows the flat portion of the non-facing portion 11N and the first flap 1F to hold each end of the second sheet 20 in the width direction 20Y, thereby holding the second sheet 20. The flat portion of the non-facing portion 11N is the flat portion of the non-facing portion 11N other than the upright portions of the first flap 1F, etc.

[0028] At least one first flap 1F is preferably formed by a notch provided in the non-facing portion 11N. By forming the first flap 1F integrally with the non-facing portion 11N in this manner, the tension of the second sheet 20 is easily applied to the non-facing portion 11N via the first flap 1F.

[0029] The non-facing portion 11N of the first base portion 11 preferably has at least one first hole 1H formed by the standing of at least one first flap 1F. The first hole 1H can facilitate the absorption of external impacts. Note that the first flap 1F may be formed, for example, by fixing the base end of a small piece of a desired shape to the non-facing portion 11N with an adhesive or the like, rather than by the standing of the non-facing portion 11N. The small piece is preferably made of the same material as the non-facing portion 11N.

[0030] The shape of the outer edge of the first flap 1F is preferably U-shaped, V-shaped, or U-shaped, and more preferably U-shaped or U-shaped, which makes it easier for the first flap 1F to hold the second sheet 20. When there are multiple first flaps 1F, the shapes of the outer edges of the multiple first flaps 1F may be different from each other, but are preferably the same shape.

[0031] The outer edge of the first flap 1F shown in FIG. 1 is U-shaped, while the outer edge of a modified first flap 1F shown in FIG. 5 is U-shaped. A U-shape is a shape in which one of the line segments of a rectangle is omitted. Specifically, as shown in FIG. 5, an example of the U-shape is a shape including a first line L1 and a second line L2 and a third line L3 extending from both ends of the first line L1 toward one side L10A of one side L10A and the other side L10B defined by a virtual line L10 connecting both ends of the first line L1. The U-shape is preferably composed of the first line L1, the second line L2, and the third line L3.

[0032] The inclination angles of the second line L2 and the third line L3 relative to the first line L1 are preferably 70 degrees or more and 95 degrees or less, more preferably 80 degrees or more and 93 degrees or less, even more preferably 85 degrees or more and 91 degrees or less, and most preferably 90 degrees. The inclination angle of the second line L2 relative to the first line L1 is the inclination angle of the imaginary line segment connecting both ends of the second line L2 relative to the imaginary line segment connecting both ends of the first line L1. The inclination angle of the third line L3 relative to the first line L1 is the inclination angle of the imaginary line segment connecting both ends of the third line L3 relative to the imaginary line segment connecting both ends of the first line L1. For example, when the inclination angles of the second line L2 and the third line L3 relative to the first line L1 are 70 degrees or more and less than 90 degrees, respectively, the shape of the first flap 1F is tapered.

[0033] The second line L2 and the third line L3 are preferably straight lines. On the other hand, the first line L1 is preferably straight or has a straight line portion, and preferably has a straight line portion and curved portions on both sides of the straight line portion. When the first line L1 has curved portions on both sides of the straight line portion, the U-shape becomes rounded.

[0034] At least one first flap 1F is preferably a single flap, which makes it easier to remove the second sheet 20 from the first sheet 10.

[0035] As shown in Figure 4, the curved portion 20C preferably has a curved portion 20D. This makes it difficult for the second sheet 20 to bend in the longitudinal direction 20X and the width direction 20Y. The curved portion 20C is preferably formed, for example, by bending a flat sheet through elastic deformation. This generates a repulsive force in the curved portion 20C that causes it to return to a flat shape, making it easier to apply tension to the first sheet 10 via, for example, the first flap 1F.

[0036] 4, the distance between the first sheet 10 and the second sheet 20 in the vertical direction 11Z perpendicular to the surface of the flat portion of the non-facing portion 11N of the first base portion 11 preferably increases from both end portions 20Ya, 20Yb in the width direction 20Y of the second sheet 20 toward the center 20Yc. This makes it easier for the curved portion 20C to apply tension to the first sheet 10 in the width direction 10Y. This also makes it easier for the curved portion 20C to disperse external impacts from the second sheet 20 toward the first sheet 10.

[0037] The curved portion 20C may have a curved portion and a flat portion. In this case, as shown in Fig. 6, the curved portion 20C preferably has a first curved portion 20D1 located closer to one end 20Ya of the two ends in the width direction 20Y, a second curved portion 20D2 located closer to the other end 20Yb, and a flat portion 20E located between the first curved portion 20D1 and the second curved portion 20D2. This makes it easier for the second sheet 20 to apply tension to the first sheet 10.

[0038] Alternatively, the curved portion 20C may have a flat portion without a curved portion. In this case, as shown in Fig. 7, the curved portion 20C preferably has a first flat portion 20E1 located closer to one end 20Ya in the width direction 20Y, a second flat portion 20E2 located closer to the other end 20Yb, and a third flat portion 20E3 located between the first flat portion 20E1 and the second flat portion 20E2. This makes it easier for the second sheet 20 to apply tension to the first sheet 10.

[0039] It is preferable that the second sheet 20 is not bonded to the first sheet 10. This allows the second sheet 20 to be detached from the first sheet 10. By detaching the second sheet 20 from the first sheet 10, it becomes easier to remove the long portion 52 from the first sheet 10. It is also preferable that the second sheet 20 extends in the longitudinal direction 10X of the first sheet 10. This makes it difficult for the first sheet 10 holding the second sheet 20 to bend in the longitudinal direction 10X.

[0040] 1, the second sheet 20 is preferably located closer to the other end 10b in the longitudinal direction 10X than the first folded-back portion 12. This allows a greater distance to be placed between the handle portion 51 held by the first folded-back portion 12 and the second sheet 20, making it easier for the user to remove the handle portion 51 or the second sheet 20 from the first sheet 10.

[0041] 2 and 4, the maximum distance A between the first sheet 10 and the second sheet 20 in the vertical direction 11Z perpendicular to the surface of the flat portion of the non-facing portion 11N of the first base portion 11 is preferably greater than the thickness of the handle portion 51 in the vertical direction 11Z. This makes it easier to avoid contact between the second sheet 20 and the elongated portion 52, for example, when an external impact is applied from the second sheet 20 toward the first sheet 10.

[0042] 1, the width of the second sheet 20 is preferably smaller than the width of the non-facing portion 11N of the first base portion 11. This makes it difficult for the second sheet 20 to bend in the longitudinal direction 20X, and therefore the first sheet 10 holding the second sheet 20 also becomes difficult to bend in the longitudinal direction 10Y. The width of the second sheet 20 corresponds to the linear length of the second sheet 20 in the width direction 20Y in the plan view of the holding member 40 shown in FIG. 1. Meanwhile, the width of the non-facing portion 11N of the first base portion 11 corresponds to the linear length of the non-facing portion 11N in the width direction 10Y in the plan view of the holding member 40 shown in FIG.

[0043] As shown in FIGS. 1 and 4, the width of the second sheet 20 is preferably shorter than the length from one end 20Ya to the other end 20Yb in the width direction 20Y of the second sheet 20. This makes it easier to maintain the shape of the curved portion 20C. As described above, the width of the second sheet 20 corresponds to the linear length of the second sheet 20 in the width direction 20Y in the plan view of the retaining member 40 shown in FIG. 1. Meanwhile, the length from one end 20Ya to the other end 20Yb in the width direction 20Y of the second sheet 20 corresponds to the length from one end 20Ya to the other end 20Yb in the width direction 20Y on the surface of the second sheet 20 opposite to the first sheet 10, which corresponds to the curved length in FIG. 4.

[0044] The length of the second sheet 20 in the longitudinal direction 20X is preferably shorter than the length of the non-facing portion 11N in the longitudinal direction 10X. This makes it possible to prevent the second sheet 20 from puncturing the packaging bag when the holding member 40 is packaged in the packaging bag.

[0045] The length of the second sheet 20 in the longitudinal direction 20X is preferably longer than the length of the second sheet 20 in the width direction. This makes it easier for the second sheet 20 to cover the elongated portion 52.

[0046] The shape of the second sheet 20 in a plan view is preferably a polygon, more preferably a square, pentagon, or hexagon, even more preferably a square, and even more preferably a rectangle. The polygon may have at least one rounded corner, or all rounded corners. The rounded corners prevent the second sheet 20 from puncturing a packaging bag when the holding member 40 is packaged in the packaging bag.

[0047] The second sheet 20 preferably includes a resin layer, a paper layer, or a laminate thereof, and more preferably includes a resin layer. The laminate may include one or more resin layers and one or more paper layers, or may include two or more resin layers, or may include two or more paper layers.

[0048] The resin layer is preferably a polyolefin layer, a fluororesin layer, a polyester layer, a polyurethane layer, a polystyrene layer, a polycarbonate layer, a silicone layer, a polyamide layer, or a polyimide layer, more preferably a polyolefin layer or a fluororesin layer, and even more preferably a polyolefin layer. These may be used alone or in combination of two or more. The polyolefin layer preferably contains polyethylene, polypropylene, or a mixture thereof, more preferably contains polyethylene, and even more preferably consists of polyethylene. The fluororesin layer preferably contains polytetrafluoroethylene. The polyester layer preferably contains polyethylene terephthalate, polybutylene terephthalate, or a mixture thereof. The polyurethane layer preferably contains polyurethane. The polystyrene layer preferably contains polystyrene. The polycarbonate layer preferably contains polycarbonate. The silicone resin layer preferably contains a silicone resin. The polyamide layer preferably contains nylon. The polyimide layer preferably contains polyetherimide.

[0049] The paper layer is preferably made of fine paper, medium-quality paper, kraft paper, semi-gloss kraft paper, latex-impregnated paper, or a laminate thereof.

[0050] The thickness of the second sheet 20 is preferably 0.10 mm or more and 2.0 mm or less, more preferably 0.15 mm or more and 1.0 mm or less, and even more preferably 0.20 mm or more and 0.8 mm or less, which allows the holding member 40 to be lightweight while maintaining its strength.

[0051] As shown in Figures 1, 2, and 3, the first folded portion 12 preferably has at least one second flap 2F standing toward the handle portion 51 and at least one second hole 2H formed by the standing of the at least one second flap 2F. Furthermore, the facing portion 11F preferably has at least one third flap 3F standing toward the handle portion 51 through the at least one second hole 2H. Furthermore, it is preferable that the at least one second flap 2F and the at least one third flap 3F hold the handle portion 51. In this manner, the third flap 3F of the facing portion 11F passes through the second hole 2H of the first folded portion 12 to hold the handle portion 51. This configuration makes it easier to maintain the overlapping state between the first folded portion 12 and the facing portion 11F, making the first sheet 10 less likely to bend during transportation or when removed from a packaging box, etc. Furthermore, this makes it easier for the second flap 2F and the third flap 3F to overlap, and as a result, the second flap 2F and the third flap 3F protect each other, making it less likely that one of the flaps will be damaged when an impact is applied to the holding member 40. In addition, the holes in the first folded portion 12 and the opposing portion 11F make it easier to absorb external impacts.

[0052] Although not shown, at least one second flap 2F in the first folded portion 12 may have a flap folded in the opposite direction to the flap's direction, with the tip of the flap inserted into a hole provided on the opposite side. The handle portion 51 can also be held by the folded portion of the flap. In this case, the flap's direction is preferably the direction opposite to the handle portion 51. For example, if the flap is formed by a notch, the flap's direction is the direction the flap faces when it is not standing. The folded portion of the flap can cover at least a portion of the handle portion 51, thereby allowing the flap to hold the handle portion 51. In this case, the flap is preferably folded in the width direction 10Y of the first sheet 10.

[0053] 1, it is preferable that at least one second flap 2F and at least one third flap 3F are not covered by the second sheet 20. This makes it easier to remove the handle portion 51 from the holding member 40.

[0054] As shown in Fig. 1, it is preferable that the at least one second flap 2F and the at least one third flap 3F each include a pair of flaps facing each other in the longitudinal direction 10X. Alternatively, as shown in Fig. 9 described later, the at least one second flap 2F and the at least one third flap 3F may each include a pair of flaps facing each other in the width direction 10Y. By holding the handle portion 51 with the pair of flaps, the handle portion 51 is less likely to come off the holding member 40 during transportation, etc.

[0055] The at least one second flap 2F and the at least one third flap 3F may each be a single flap. In this case, for example, the second flap 2F and the third flap 3F may be configured to cover the entire handle portion 51, and new cuts may be provided in the first folded portion 12, and the tips of the second flap 2F and the third flap 3F may be inserted into the cuts to hold the handle portion 51.

[0056] The shape of the outer edge of at least one second flap 2F and at least one third flap 3F is preferably U-shaped, V-shaped, or U-shaped, and more preferably U-shaped or U-shaped. This makes it easier for the second flap 2F and the third flap 3F to hold the handle portion 51. For the U-shaped shape, refer to the description of the shape of the outer edge of the first flap 1F above. When there are multiple second flaps 2F, the shapes of the outer edges of the multiple second flaps 2F may be different from each other, but are preferably the same shape. Furthermore, when there are multiple third flaps 3F, the shapes of the outer edges of the multiple third flaps 3F may be different from each other, but are preferably the same shape.

[0057] It is preferable that the shapes of the outer edges of at least one second flap 2F and at least one third flap 3F are the same or similar to each other, which makes it easier for the second flap 2F and the third flap 3F to reinforce each other.

[0058] At least one third flap 3F is preferably formed by a notch provided in the facing portion 11F. Furthermore, the facing portion 11F preferably has at least one third hole 3H formed by the standing of at least one third flap 3F. The third hole 3H can absorb external impacts.

[0059] The non-facing portion 11N of the first base portion 11 preferably has at least one fourth flap 4F standing up toward the elongated portion 52. Furthermore, it is preferable that the at least one fourth flap 4F is covered by the second sheet 20 and holds the elongated portion 52. This makes it easier for the fourth flap 4F and the elongated portion 52 to be protected by the second sheet 20. Furthermore, it is preferable that the fourth flap 4F does not contact the second sheet 20. This makes it possible to avoid friction between the second sheet 20 and the fourth flap 4F.

[0060] 1, it is preferable that at least one fourth flap 4F has a flap extending from one end side 10Ya to the other end side 10Yb in the width direction 10Y of the first sheet 10, and a flap extending from the other end side 10Yb to the one end side 10Ya. This makes it difficult for the elongated portion 52 to come off the first sheet 10 during transportation, etc.

[0061] As shown in Fig. 3, at least one fourth flap 4F is preferably formed by a notch provided in the non-facing portion 11N. Furthermore, the non-facing portion 11N preferably has at least one fourth hole 4H formed by the standing of at least one fourth flap 4F. The fourth hole 4H can absorb external impacts.

[0062] The shape of the outer edge of at least one fourth flap 4F is preferably U-shaped, V-shaped, U-shaped, or S-shaped, and more preferably U-shaped or U-shaped. This makes it easier for the user to pick up the tip of the fourth flap 4F. For the U-shaped shape, see the description of the shape of the outer edge of the first flap 1F above. Furthermore, when there are multiple fourth flaps 4F, the shapes of the outer edges of the multiple fourth flaps 4F may be different from each other, but are preferably the same shape. It is preferable that at least one fourth flap 4F is a single flap. This makes it easier to remove the elongated portion 52 from the fourth flap 4F.

[0063] As shown in FIG. 2, the shortest distance (cm) from the proximal end of the fourth flap 4F to the distal end of the handle portion 51 is preferably 40 times or less, and more preferably 25 times or less, the thickness (cm) of the handle portion 51 in the vertical direction 11Z. This makes it easier for the long portion 52 to be lifted from the handle portion 51 side, making it easier for the user to pinch and remove the long portion 52. On the other hand, this magnification is preferably 5 times or more, and more preferably 8 times or more. This makes it possible to prevent the long portion 52 from being excessively lifted from the handle portion 51 side.

[0064] As shown in FIG. 1, the width of the first folded portion 12 is preferably smaller than or the same as the width of the first base portion 11, and more preferably smaller than the width of the first base portion 11. This makes it easier to store the holding member 40 holding the medical instrument 50A in a packaging bag, a packaging box, or the like. These widths are lengths in the width direction 10Y of the first sheet 10. The difference between the width of the first folded portion 12 and the width of the first base portion 11 is preferably 1 mm or more, and more preferably 5 mm or more. On the other hand, this difference is preferably 30 mm or less, and more preferably 10 mm or less. This makes it easier to align the positions of the second flap 2F and the third flap 3F.

[0065] The thickness of the first base portion 11 and the first folded portion 12 is preferably 0.10 mm or more and 2.0 mm or less, more preferably 0.15 mm or more and 1.0 mm or less, and even more preferably 0.20 mm or more and 0.8 mm or less, respectively, which allows the holding member 40 to be lightweight while maintaining its strength.

[0066] It is preferable that the first base portion 11 extends in the longitudinal direction 10X. This makes it easier for the first base portion 11 to hold the elongated portion 52. It is preferable that the length of the first base portion 11 in the longitudinal direction 10X is longer than the length of the first folded portion 12 in the longitudinal direction 10X. This makes it possible to secure an area for the facing portion 11F and the non-facing portion 11N adjacent to each other in the longitudinal direction 10X.

[0067] The length of the first base portion 11 in the longitudinal direction 10X is preferably 10 cm or more, more preferably 50 cm or more, and even more preferably 100 cm or more, and is preferably 300 cm or less, more preferably 200 cm or less, and even more preferably 150 cm or less. The length of the first base portion 11 in the width direction 10Y is preferably 3 cm or more, more preferably 5 cm or more, and even more preferably 7 cm or more, and is preferably 20 cm or less, more preferably 15 cm or less, and even more preferably 10 cm or less.

The polygon preferably has at least one rounded corner, and more preferably all rounded corners. Rounded corners can prevent the first base portion 11 from puncturing the packaging bag.

[0069] The shape of the first folded portion 12 in a plan view is preferably a polygon. The polygon is preferably a square, pentagon, or hexagon, more preferably a square, and even more preferably a rectangle. This makes it easier to ensure a contact area between the first folded portion 12 and the facing portion 11F.

[0070] The length of the first folded portion 12 in the longitudinal direction 10X is preferably longer than the length of the first folded portion 12 in the width direction 10Y. Specifically, the length of the first folded portion 12 in the longitudinal direction 10X is preferably 1.2 times or more, more preferably 1.4 times or more, preferably 2.5 times or less, and more preferably 2.0 times or less, the length of the first folded portion 12 in the width direction 10Y. This makes it easier to arrange the proximal part of the elongated portion 52 and the handle portion 51 in the first folded portion 12.

[0071] Each of the first base portion 11 and the first folded portion 12 preferably includes a resin layer, a paper layer, or a laminate thereof, and more preferably includes a resin layer.

This allows the third sheet 30 to compensate for the length of the first sheet 10 in the longitudinal direction 10X when the length of the first sheet 10 in the longitudinal direction 10X is short. Furthermore, in the manufacturing process, the first sheet 10 and the third sheet 30 can be separately machined into the desired shapes and then joined together, improving workability during manufacturing and reducing the cost of the retaining member 41. The first sheet 10 and the third sheet 30 may be joined by fusing a part of the third sheet 30 and a part of the first sheet 10 by heating, or by bonding them with an adhesive.

[0078] The distal end 52B of the elongated portion 52 is preferably disposed on the third sheet 30. Furthermore, similar to the first sheet 10, the third sheet 30 preferably has at least one first flap 1F that holds the second sheet 20. This allows, for example, the distal end 52B of the elongated portion 52 and its vicinity to be protected by the third sheet and the second sheet 20.

[0079] It is preferable that at least a portion of one end side 30a in the longitudinal direction 10X of the third sheet 30 is located on the non-facing portion 11N of the first base portion 11. This makes it easier to cover the holding member 41 holding the medical instrument 50A with a packaging bag or the like in the direction from one end side 10a to the other end side 10b in the longitudinal direction 10X of the first sheet 10.

[0080] The shape of the third sheet 30 in plan view is preferably polygonal, more preferably quadrangular, pentagonal, or hexagonal, even more preferably quadrangular, and even more preferably rectangular. The polygon preferably has at least one rounded corner, and more preferably all rounded corners. Rounded corners can prevent the third sheet 30 from puncturing the packaging bag.

[0082] As shown in FIG. 9 , in the holding member 42 according to the third embodiment, the medical instrument 50B includes a handle portion 51 and an elongated portion 52 extending from a distal portion of the handle portion 51. The medical instrument 50B preferably further includes an electric wire 53, one end 53a of which is connected to a proximal portion 51a of the handle portion 51. Furthermore, at least a portion of the electric wire 53 is disposed in the non-facing portion 11N of the first base portion 11, and the non-facing portion 11N preferably has at least one fifth flap 5F standing toward the electric wire 53. Preferably, the at least one fifth flap 5F is covered by the second sheet 20 and holds the electric wire 53. This protects the fifth flap 5F from damage during transport, etc. Furthermore, the fifth flap 5F preferably does not contact the second sheet 20. This prevents friction between the second sheet 20 and the fifth flap 5F.

[0083] At least one fifth flap 5F preferably includes a flap extending from one end side 10Ya toward the other end side 10Yb in the width direction 10Y of the first sheet 10, and a flap extending from the other end side 10Yb toward the one end side 10Ya. This makes it difficult for the wires 53 to come off the holding member 42 during transportation, etc.

[0084] At least one fifth flap 5F is preferably formed by a notch provided in the non-facing portion 11N. Furthermore, the non-facing portion 11N preferably has at least one fifth hole formed by the standing of at least one fifth flap F. The fifth hole can absorb external impacts.

[0085] The shape of the outer edge of at least one fifth flap 5F is preferably U-shaped, V-shaped, U-shaped, or S-shaped, and more preferably U-shaped or U-shaped. This makes it easier for the user to pick up the tip of the fifth flap 5F. For the U-shaped shape, see the description of the shape of the outer edge of the first flap 1F above. Furthermore, when there are multiple fifth flaps 5F, the shapes of the outer edges of the multiple fifth flaps 5F may be different from each other, but are preferably the same shape. It is preferable that at least one fifth flap 5F is a single flap. This makes it easier to remove the electric wires 53 from the first sheet 10.

[0086] It is preferable that at least one second flap 2F and at least one third flap 3F each include a flap standing toward the electric wire 53. The flap can hold a part of the electric wire 53.

The connector 54 is disposed in the non-facing portion 11N of the first base portion 11. The non-facing portion 11N preferably has at least one sixth flap 6F standing toward the connector 54. The at least one sixth flap 6F is preferably covered by the second sheet 20 and holds the connector 54. This protects the sixth flap 6F and the connector 54 from damage during transport, etc. Furthermore, the sixth flap 6F preferably does not contact the second sheet 20. This prevents friction between the second sheet 20 and the sixth flap 6F. Furthermore, since the connector 54 is disposed in the non-facing portion 11N, the electric wire 53 can be easily arranged in a straight line, thereby reducing the number of curved portions of the electric wire 53 formed when the electric wire 53 is fixed to the holding member 42.

[0089] The connector 54 is preferably connectable to a power source for supplying high-frequency current. The connector 54 is preferably cylindrical or polygonal prism-shaped. The polygonal prism may have at least one rounded corner.

[0090] It is preferable that the at least one sixth flap 6F includes a pair of flaps facing each other in the longitudinal direction 10X, which can make it easier to reduce movement of the connector 54.

[0091] At least one sixth flap 6F is preferably formed by a notch provided in the non-facing portion 11N. Furthermore, the non-facing portion 11N preferably has at least one sixth hole formed by the standing of at least one sixth flap 6F. The sixth hole can absorb external impacts.

[0092] The shape of the outer edge of at least one flap 6F is preferably U-shaped, V-shaped, U-shaped, or S-shaped, more preferably U-shaped or U-shaped, and even more preferably U-shaped. This can facilitate reducing the movement of the connector 54. When there are multiple sixth flaps 6F, the shapes of the outer edges of the multiple sixth flaps 6F may be different from one another, but are preferably the same. For the U-shaped shape, see the description of the shape of the outer edge of the first flap 1F above. Furthermore, when the outer edge of the flap 6F is U-shaped, as shown in FIG. 10, the first line L1 forming the U-shape may have a first linear portion L11, a second linear portion L12, and an arc-shaped portion L13 located between the first linear portion L11 and the second linear portion L12. Furthermore, the arc-shaped portion L13 may be connected to the first straight portion L11 and the second straight portion L12 via a tapered portion L14 that tapers toward the arc-shaped portion L13. This makes it easier for the sixth flap 6F to hold the connector 54. In Figure 9, the sixth flap 6F and the second and third flaps 2F and 3F that hold the distal portion 51b of the handle portion 51 each have the same outer edge shapes as those shown in Figure 10.

[0093] The medical instrument 50B is preferably a puncture device for puncturing biological tissue, such as the atrial septum. For example, the medical instrument 50B is preferably capable of passing a current from a high-frequency current power source to the distal end 52B via the connector 54, the electric wire 53, the handle portion 51, and the elongated portion 52. A return electrode may be used for this current application. In this case, the elongated portion 52 preferably includes a metal tube, a metal member disposed within the distal end of the metal tube and extending longitudinally, and a metal tip connected to the distal end of the metal member. Furthermore, the metal tip at the distal end is preferably one that generates heat upon application of high-frequency current. This facilitates puncturing the atrial septum. At least a portion of the metal tube, the metal member, or the metal tip may be covered with a resin tube. The handle portion 51 may also include a syringe port for delivering a liquid, such as saline or a contrast agent, through the elongated portion 52.
