BEST MODE FOR CARRYING OUT THE INVENTION
[0010] Hereinafter, the present invention will be described more specifically based on the following embodiments. However, the present invention is not limited by the following embodiments, and it is of course possible to appropriately modify and implement it within the range that can conform to the gist of the foregoing and following descriptions, and all of them are included in the technical scope of the present invention. In each drawing, for the sake of convenience, reference numerals of members and the like may be omitted, but in such a case, reference shall be made to the specification and other drawings. In addition, since the dimensions of various members in the drawings are prioritized for facilitating the understanding of the features of the present invention, they may be different from the actual dimensions.
[0011] The holding member according to the first embodiment is a holding member that holds a wound medical tubular body and has a plurality of first recesses into which the tubular body is fitted and a second recess into which a jig is fitted.
[0012] The holding member according to the second embodiment is a holding member that holds a wound medical tubular body and has a plurality of first recesses into which the tubular body is fitted and a convex portion into which a jig is fitted.
[0013] By attaching the holding member according to the first or second embodiment to a wound medical tubular body, fitting a jig into the recess and / or convex portion of the holding member, and then applying a load in the planar direction to the holding member via the jig, the overall shape of the wound tubular body can be deformed, and as a result, it is possible to easily flatten the wound tubular body.
[0014] The details of the retaining member according to the first embodiment will be described below with reference to Figures 1 to 7. Figure 1 is a side view of the retaining member according to the first embodiment, and Figure 2 is a perspective view. Figure 3 is a plan view of a tubular body to which the retaining member is attached. Figure 4 is a side view (partial cross-sectional view) of the retaining member in Figure 3 with a jig fitted into the second recess. Figure 5 is a cross-sectional view of AA in Figure 1, and Figure 6 is a cross-sectional view of BB in Figure 1. Figure 7 is a side view of a modified example of the retaining member according to the first embodiment.
[0015] As shown in Figures 1 to 4, the holding member 10a according to the first embodiment is a holding member 10a for holding a wound medical tubular body 1, and has a plurality of first recesses 11 into which the tubular body 1 is fitted, and a second recess 12 into which the jig 5 is fitted.
[0016] The multiple first recesses 11 can each be designed to accommodate a wound medical tubular body 1. For example, as shown in Figure 1, it is preferable that each of the multiple first recesses 11 has an arc-shaped portion, an elliptical arc-shaped portion, etc., which are arc-shaped in a side view of the holding member 10a.
[0017] As shown in Figure 1, it is preferable that each of the multiple first recesses 11 has an enlarged portion 11a in which the cross-sectional area in the direction X1 perpendicular to the depth direction Y1 of the first recess 11 increases toward the outside O1 in the depth direction Y1, and a reduced portion 11b in which the cross-sectional area decreases toward the outside O1. This makes it difficult for the tubular body 1, which is fitted and fixed in the first recess 11, to come out of the first recess 11. The said cross-sectional area is the area of the region between the inner walls 11w of the first recess 11, as shown in Figure 5, and is the area of the region that is not hatched in Figure 5.
[0018] As shown in Figure 2, the multiple first recesses 11 are groove-shaped, and it is preferable that the extension directions of the multiple first recesses 11 are parallel to each other. This makes it easier to maintain the wound tubular body 1 in an annular shape, as shown in Figure 3.
[0019] The number of first recesses 11 on the retaining member 10a is preferably 2 or more and 8 or less, more preferably 2 or more and 6 or less, and even more preferably 2 or more and 4 or less.
[0020] The second recess 12 can be any recess that can accommodate a jig 5, such as the one shown in Figure 4. For example, as shown in Figure 3, multiple holding members 10a are attached to a tubular body 1 around which the member is wound, and a gripping tool 4 such as a chuck equipped with a jig 5, as shown in Figure 4, is used to fit the protrusion 5a of the jig 5 into the second recess 12. Then, by applying a load in the planar direction D3 to the member 10a using the gripping tool 4 and the jig 5, the wound tubular body 1 can be easily flattened. It is preferable that the gripping tool 4 and the jig 5 are fixed to a member that can move the gripping tool 4 and the jig 5 in a straight line, such as a uniaxial actuator. The up and down arrows in Figure 4 show an example of the direction in which the gripping tool 4 grips the member 10a.
[0021] In Figure 3, D1 indicates the direction from the center outward of the winding portion 1a of the tubular body 10, and D2 indicates the direction from the outside of the winding portion 1a of the tubular body 10 towards the center. By applying a load in direction D1 to multiple holding members 10a, the wound tubular body 1 can be easily made flat. However, a load in direction D2 may be applied to some of the holding members 10a.
[0022] When applying a load to the retaining member 10a in direction D1, the retaining member 10a may be pulled in direction D1, or the retaining member 10a may be pushed in direction D1. Also, when applying a load to the retaining member 10a in direction D2 from the outside of the winding portion 1a toward the center, the retaining member 10a may be pulled in direction D2, or the retaining member 10a may be pushed in direction D2.
[0023] As shown in Figure 1, it is preferable that the length L2 in the depth direction Y2 of the second recess 12 is shorter than the length L1 in the depth direction Y1 of the first recess 11. This makes it easier to remove the protrusion 5a of the jig 5 from the second recess 12 after applying a load in the planar direction D3 to the holding member 10a. The length L2 is preferably 0.9 times or less of the length L1, more preferably 0.7 times or less, even more preferably 0.5 times or less, and even more preferably 0.4 times or less. On the other hand, the length L2 is preferably 0.1 times or more of the length L1, and more preferably 0.2 times or more. This makes it easier to apply a load in the planar direction D3 to the holding member 10a via the jig 5.
[0024] The shape of the second recess 12 is preferably a pyramidal pyramid, cone, prism, cylinder, truncated pyramid, truncated cone, hemisphere, semi-ellipsoid, or a combination thereof. Of these, a pyramidal pyramid, cone, truncated pyramid, truncated cone, hemisphere, or semi-ellipsoid is more preferred. This makes it easier to fit the jig 5. Furthermore, the shape of the opening of the second recess 12 on the second surface S2, which will be described later, is preferably a polygon, circle, ellipse, or a combination thereof, with a circle being more preferred. A rectangle is preferred as a polygon.
[0025] The maximum cross-sectional area of the second recess 12 in the direction X2 perpendicular to the depth direction Y2 of the second recess 12 is preferably smaller than the maximum cross-sectional area of the first recess 11 in the direction X1 perpendicular to the depth direction Y1 of the first recess 11. This improves the strength of the retaining member 10a. The maximum cross-sectional area of the second recess 12 is preferably 0.9 times or less, more preferably 0.7 times or less, even more preferably 0.5 times or less, and even more preferably 0.4 times or less, of the maximum cross-sectional area of the first recess 11. On the other hand, the ratio is preferably 0.1 times or more, and more preferably 0.2 times or more. This makes it easier to apply a load in the planar direction D3 to the retaining member 10a via the jig 5. It is also preferable that the opening area of the second recess 12 on the second surface S2, which will be described later, satisfies the above ratio. The following will explain each maximum cross-sectional area with reference to Figures 5 and 6.
[0026] For example, as shown in Figure 5, the cross-sectional area of the first recess 11 in direction X1 is the area of each region between the inner walls 11w of the first recess 11. In the embodiment of Figure 1, the cross-sectional area of the first recess 11 in direction X1 increases towards the outer O1 in the enlarged portion 11a and decreases towards the outer O1 in the reduced portion 11b. Therefore, in the embodiment of Figure 1, the position of the upper end of the enlarged portion 11a, i.e., the AA cross-section position, is the position where the cross-sectional area of the first recess 11 in direction X1 is maximum. That is, the area of each region between the inner walls 11w of the first recess 11 in Figure 5, which is the AA cross-section in Figure 1, is the maximum cross-sectional area of the first recess 11 in direction X1 in that embodiment.
[0027] For example, as shown in Figure 6, the cross-sectional area of the second recess 12 in direction X2 is the area of the region between the inner walls 12w of the second recess 12. In the embodiment of Figure 1, the cross-sectional area of the second recess 12 in direction X2 increases towards the outside O2 in the enlarged portion 12a. Therefore, in the embodiment of Figure 1, the position of the lower end of the enlarged portion 12a, i.e., the BB cross-section position, is the position where the cross-sectional area of the second recess 12 in direction X2 is maximum. That is, the area of the region between the inner walls 12w of the second recess 12 in Figure 6, which is the BB cross-section of Figure 1, is the maximum cross-sectional area of the second recess 12 in direction X2 in this embodiment. Note that in Figure 1, the dashed line of the BB cross-section is shown slightly above the position of the lower end of the enlarged portion 12a in order to make it easier to see.
[0028] As shown in Figures 5 and 6, when the first recess 11 is groove-shaped and has a width direction, the maximum length L5 of the second recess in that width direction is preferably 0.5 times or more the maximum length L4 of the first recess 11 in that width direction. This makes it easier to apply a load in the planar direction D3 to the holding member 10a via the jig 5. This multiplier is more preferably 0.7 times or more. On the other hand, the maximum length L5 is preferably less than or equal to the maximum length L4, and more preferably smaller than the maximum length L4. This improves the strength of the holding member 10a. In Figure 5, the width direction corresponds to direction X1, and in Figure 6, the width direction corresponds to direction X2.
[0029] As shown in Figure 1, it is preferable that the second recess 12 has an enlarged portion 12a in which the cross-sectional area in the direction X2 perpendicular to the depth direction Y2 of the second recess 12 is larger toward the outer side O2 in the depth direction Y2, and does not have a reduced portion in which the cross-sectional area is smaller toward the outer side O2. This makes it easier to remove the protrusion 5a of the jig 5 from the second recess 12 after a load in the planar direction D3 is applied to the holding member 10a.
[0030] The number of recesses 12 in the retaining member 10a is preferably 1 or more and 5 or less, more preferably 1 or more and 3 or less, and even more preferably 1.
[0031] The retaining member 10a may contain polyethylene, polypropylene, polyolefin resin such as ethylene-propylene copolymer, polyvinyl chloride resin, polystyrene resin, polyamide resin, polycarbonate resin, acrylic resin, or a mixture thereof. It is preferable that the retaining member 10a is made of resin.
[0032] As shown in Figures 1 and 2, the retaining member 10a has a first surface S1 and a second surface S2 opposite to the first surface S1, preferably the first surface S1 has a plurality of first recesses 11 and the second surface S2 has a second recess 12. By having the second recess 12 on the surface opposite to the surface where the plurality of first recesses 11 are provided, it is possible to easily fit the protrusion 5a of the jig 5 into the second recess 12. It is preferable that the first surface S1 and the second surface S2 are parallel. It is also preferable that the second recess 12 does not penetrate from the first surface S1 to the second surface S2. Furthermore, it is preferable that the second recess 12 is located inside the outer edge of the second surface S2. This improves the strength of the retaining member 10a. The retaining member 10a may have a plurality of first recesses 11 on the first surface S1 and the second surface S2, respectively.
[0033] Furthermore, as shown in Figure 2, the retaining member 10a may have a third surface S3 connected at one end to one end of the first surface S1 and one end of the second surface S2 in direction X1, and a fourth surface S4 connected at one end to the other end of the first surface S1 and the other end of the second surface S2 in direction X1.
[0034] Furthermore, as shown in Figure 2, the retaining member 10a may have a fifth surface S5, one end of which is connected to one end of the first surface S1 and one end of the second surface S2 in a direction Z1 perpendicular to directions X1 and Y1, and a sixth surface S6, one end of which is connected to the other end of the first surface S1 and the other end of the second surface S2 in a direction Z1.
[0035] The retaining member 10a may have a second recess 12 on the first surface S1, the third surface S3, the fourth surface S4, the fifth surface S5, the sixth surface S6, or a plurality of these surfaces and the second surface S2. Preferably, the retaining member 10a has a second recess 12 on the second surface S2, or on the first surface S1 and the second surface S2. This makes it easier to apply a load in the planar direction D3 to the retaining member 10a via the jig 5. The retaining member 10a may also have a plurality of first recesses 11 on the first surface S1 and the second surface S2, respectively.
[0036] As described above, the retaining member 10b in Figure 7 is a side view of a modified example of the retaining member 10a according to the first embodiment. As shown in Figure 7, the retaining member 10b may have a second recess 12 on the first surface S1 which is provided with a plurality of first recesses 11. This allows the first recesses 11 to prevent the crack from propagating even if a crack occurs in the second recess 12 when a load is applied to the retaining member 10b, thus preventing overall damage to the retaining member 10b.
[0037] The tubular body 1 to which the retaining members 10a and 10b are attached is preferably one in which a medical length 3 is inserted, as shown in Figures 3 and 4. By inserting the medical length 3 into the tubular body 1, the medical length 3 can be protected. Examples of the medical length 3 include balloon catheters, guiding catheters, inner catheters inserted inside guiding catheters, and guide wires. The medical length 3 may have a handle at its proximal end 3a.
[0038] The tubular body 1 may contain polyethylene, polypropylene, polyolefin resin such as ethylene-propylene copolymer and ethylene-vinyl acetate copolymer, polyvinyl chloride resin, polystyrene resin, polyamide resin, polyimide resin, or mixtures thereof. The shape of the outer edge of the cross-section in the thickness direction of the tubular body 1 is preferably circular, elliptical, polygonal, rounded polygonal, or a combination thereof, more preferably circular, elliptical, or rounded polygonal, even more preferably circular or elliptical, and even more preferably circular.
[0039] The details of the retaining member according to the second embodiment will be described below with reference to Figures 8 to 10. Figure 8 is a side view of the retaining member according to the second embodiment. Figure 9 is a cross-sectional view of Figure 8 at cross-section CC. Figure 10 is a side view of a modified example of the retaining member according to the second embodiment. Note that the cross-sectional view AA in Figure 8 has the same shape as the cross-sectional view AA in Figure 1, i.e., Figure 5.
[0040] As shown in Figure 8, the holding member 10c according to the second embodiment is a holding member 10c for holding a wound medical tubular body 1, and has a plurality of first recesses 11 into which the tubular body 1 is fitted, and a protrusion 13 into which a jig is fitted.
[0041] For details on the components of the retaining member 10c, etc., according to the second embodiment, refer to the description of the retaining members 10a, 10b, etc., according to the first embodiment. Below, we will mainly describe the configuration of the protrusion 13 of the retaining member 10c according to the second embodiment.
[0042] The protrusion 13 only needs to be able to be fitted into a jig having a recess. For example, by attaching multiple holding members 10c to a wound tubular body and using a gripping tool such as a chuck equipped with a jig, the recess of the jig can be fitted into the protrusion 13, and then a load in the planar direction D3 can be applied to the holding members 10c via the jig, making it easier to flatten the wound tubular body.
[0043] The length L3 of the protrusion 13 in the height direction Y3 is preferably shorter than the length L1 of the first recess 11 in the depth direction Y1. This makes it easier to remove the recess of the jig from the protrusion 13 after applying a load in the planar direction D3 to the holding member 10c. The length L3 is preferably 0.9 times or less of the length L1, more preferably 0.7 times or less, even more preferably 0.5 times or less, and even more preferably 0.4 times or less. On the other hand, the length L3 is preferably 0.1 times or more of the length L1, and more preferably 0.2 times or more. This makes it easier to apply a load in the planar direction D3 to the holding member 10c via the jig.
[0044] The shape of the protrusion 13 is preferably a pyramidal pyramid, cone, prism, cylinder, truncated pyramid, truncated cone, hemisphere, semi-ellipsoid, or a combination thereof. Of these, a pyramidal pyramid, cone, truncated pyramid, truncated cone, hemisphere, or semi-ellipsoid is more preferred. This makes it easier to fit the jig. Furthermore, it is preferable that the protrusion 13 is integrally molded with the main body portion of the holding member 10c.
[0045] As shown in Figure 8, the retaining member 10c preferably has a first surface S1 and a second surface S2 facing the first surface S1, with the first surface S1 having a plurality of first recesses 11 and the second surface S2 having a protrusion 13. By having the protrusion 13 on the surface facing the surface where the plurality of first recesses 11 are provided, it is possible to easily fit the recesses of the jig into the protrusion 13.
[0046] The maximum cross-sectional area of the protrusion 13 in the direction X3 perpendicular to the height direction Y3 is preferably smaller than the maximum cross-sectional area of the first recess 11 in the direction X1 perpendicular to the depth direction Y1 of the first recess 11. This makes the protrusion 13 less likely to be damaged. The maximum cross-sectional area of the protrusion 13 is preferably 0.9 times or less, more preferably 0.7 times or less, even more preferably 0.5 times or less, and even more preferably 0.4 times or less than the maximum cross-sectional area of the first recess 11. On the other hand, the ratio is preferably 0.1 times or more, and more preferably 0.2 times or more. This makes it easier to apply a load in the planar direction D3 to the holding member 10c via a jig.
[0047] The maximum cross-sectional area of the first recess 11 in direction X1 is the area of each region between the inner walls 11w of the first recess 11 shown in Figure 5. For details, please refer to the description of the maximum cross-sectional area of the first recess 11 of the retaining member according to the first embodiment.
[0048] In the configuration shown in Figure 8, for example, the cross-sectional area of the convex portion 13 in direction X3 increases towards the apex 13a of the convex portion 13. Therefore, in the configuration shown in Figure 8, the position of the upper end of the convex portion 13, i.e., the CC cross-section position, is the position where the cross-sectional area of the convex portion 13 in direction X3 is maximum. That is, the area of the region of the convex portion 13 in Figure 9, which is the CC cross-section in Figure 8, is the maximum cross-sectional area of the convex portion 13 in direction X3. Note that in Figure 8, the dashed line of the CC cross-section is shown slightly below the position of the upper end of the convex portion 13 in order to make it easier to see.
[0049] The cross-sectional shape of the protrusion 13 in the CC section is preferably polygonal, circular, elliptical, or a combination thereof, with circular being more preferable. A rectangle is preferred as a polygon.
[0050] As shown in Figures 8 and 9, when the first recess 11 is groove-shaped and has a width direction, the maximum length L6 of the protrusion 13 in that width direction is preferably 0.5 times or more the maximum length L4 of the first recess 11 in that width direction. This makes it easier to apply a load in the planar direction D3 to the holding member 10c via the jig. This multiplier is more preferably 0.7 times or more. On the other hand, the maximum length L6 is preferably less than or equal to the maximum length L4, and preferably smaller than the maximum length L4. This makes it easier to remove the recess of the jig from the protrusion 13 after applying a load in the planar direction D3 to the holding member 10. In Figure 8, the width direction corresponds to directions X1 and X3, and in Figure 9, the width direction corresponds to direction X3.
[0051] Preferably, the protrusion 13 has a reduced portion 13b in which the cross-sectional area in the direction X3 perpendicular to the height direction Y3 of the protrusion 13 is smaller toward the top 13a of the protrusion 13, and does not have an enlarged portion in which the cross-sectional area is larger toward the top 13a of the protrusion 13. This makes it easier to remove the recess of the jig from the protrusion 13 after a load in the planar direction D3 has been applied to the holding member 10c.
[0052] The number of protrusions 13 on the retaining member 10c is preferably 1 or more and 5 or less, more preferably 1 or more and 3 or less, and even more preferably 1.
[0053] The retaining member 10c may have a second protrusion 13 on the first surface S1, the third surface S3, the fourth surface S4, the fifth surface S5, the sixth surface S6, or a plurality of these surfaces and the second surface S2. Preferably, the retaining member 10c has a second protrusion 13 on the second surface S2, or on the first surface S1 and the second surface S2. For details of each surface, refer to the description of the retaining member 10a according to the first embodiment. The retaining member 10c may also have a plurality of first recesses 11 on the first surface S1 and the second surface S2, respectively. The retaining member 10c may also have a protrusion 13 and the second recess 12 described above.
[0054] As described above, the retaining member 10d in Figure 10 is a side view of a modified example of the retaining member 10c according to the second embodiment. As shown in Figure 10, the retaining member 10d may have a protrusion 13 on the first surface S1 which is provided with a plurality of first recesses 11. This makes it easier to distribute the load on the protrusion 13 to the first recesses 11, etc., when a load is applied to the retaining member 10, thus making it less likely for the protrusion 13 to be damaged.
