Description

[Technical Field]

[0001] The present invention relates to a container for an elongated medical device. [Background technology]

[0002] A guidewire is a device that is inserted into a blood vessel prior to a therapeutic device, such as a catheter or stent, for intravascular treatment in order to guide the device to a target site. Because guidewires are long, they are stored and transported in a container in which a long tubular body is wound in a spiral shape (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-037660 Summary of the Invention [Problem to be solved by the invention]

[0004] The guidewire is completely removed from the tubular housing to be immersed in saline or the like. However, the guidewire can become uncontrollable due to its long length and the repulsive force of the metal wire. This lack of control makes it difficult to keep the guidewire in the sterile field and can lead to it falling off the operating table. In particular, a guidewire inserted through an artery in the wrist is even more difficult to control because it is much longer than the patient's height.

[0005] Furthermore, the entire guidewire is pulled out from the end opening of the tubular body of the housing. At this time, the outer circumferential surface of the guidewire may rub against the end opening of the tubular body of the housing, potentially damaging the outer circumferential surface of the guidewire. Therefore, if the outer circumferential surface of the guidewire is provided with a hydrophilic coating, the hydrophilic coating may be damaged. Damage to the hydrophilic coating may reduce the ease of insertion and operability of the guidewire into a blood vessel.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a storage device that makes it easy to keep a long device being removed in a sterile field and that can prevent damage to the outer surface of the long device. [Means for solving the problem]

[0007] The above object can be achieved by the invention described in (1) below. (1) A storage device according to the present invention is a storage device having a spirally wound tubular body capable of storing a long medical device, the tubular body having a bottom with a side opening extending from a first end opening located at both ends of the tubular body in the longitudinal direction to a second end opening, and a lid capable of covering the side opening, wherein one of the lid and the bottom has at least one claw capable of contacting the other, and the other has a limiting wall formed along the longitudinal direction, slidable against the claw, and capable of limiting movement of the claw in a direction away from the bottom, and the bottom and the lid can be attached and detached by rotating the lid relative to the bottom along the longitudinal direction, thereby moving the claw along the limiting wall. [Effects of the Invention]

[0008] The container described in (1) above allows the long device to be removed from the side opening of the bottom while still bundled in a wound state by removing the lid from the bottom. This makes it easier to control the long device being removed and keep it in a sterile field. Furthermore, it is not necessary to pull the long device out of the first or second end opening of the tubular body. This prevents the outer surface of the long device from rubbing against the edge of the first or second end opening of the tubular body and causing damage.

[0009] (2) In the container described in (1) above, the lid may have a lid body made of resin and a shape-retaining member formed in a wound shape from a material harder than the lid body and fixed to the lid body. This allows the lid to maintain its wound shape by the shape-retaining member even after being removed from the bottom, making it easy to reattach to the bottom. Furthermore, the shape-retaining member imparts rigidity to the lid and can effectively transmit rotational force, making it easy to rotate the lid when attaching or detaching the bottom and lid.

[0010] (3) In the container described in (1) or (2) above, the bottom may have at least one removable portion sandwiched between two breakable rupture portions in a portion of the longitudinal direction, whereby an operator can easily remove the long device exposed from the bottom at the position where the removable portion is removed, while still bundled in a wound state, through a side opening in the bottom.

[0011] (4) The container according to any one of (1) to (3) above may have a rotation assisting member connectable to the bottom or the lid, thereby facilitating rotational operation when attaching or detaching the bottom and the lid of the container.

[0012] (5) In the container described in (4) above, the rotation assist member may have at least one bottom clip connected to the bottom and at least one lid clip connected to the lid, whereby an operator can easily attach and detach the bottom and lid of the container by supporting one clip with a finger and pressing the other clip with another finger along the longitudinal axis of the tubular body.

[0013] (6) In the container described in (4) above, the rotation assist member may have a plurality of lid clips connectable to the lid, a gripping portion disposed on the tubular body toward the center of the winding of the tubular body, and a connecting portion connecting each of the lid clips to the gripping portion. This allows an operator to easily rotate the lid when attaching or detaching the bottom and lid by gripping the gripping portion. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the dimensional proportions in the drawings may be exaggerated for the sake of explanation and may differ from the actual proportions.

[0016] First Embodiment As shown in FIG. 1, a container 10 according to the first embodiment is used to store and transport an elongated medical device.

[0017] An example of the long medical device accommodated in the container 10 is a guidewire 200. The guidewire 200 may be in a form in which a metal core wire is entirely coated with a highly flexible resin such as urethane, or in a form in which the base end of the core wire is coated with a fluorine-based resin such as polytetrafluoroethylene and the tip end has a coil formed by winding a metal wire. The metal forming the core wire may be a superelastic alloy such as a nickel-titanium alloy, stainless steel, or the like. The outer circumferential surface of the guidewire 200 is provided with a hydrophilic coating.

[0018] 1 to 4, the housing 10 includes a spirally wound resin tubular body 20 that houses a guidewire 200, an inserter 50 connected to the tubular body 20, at least one clip 60 that maintains the wound shape of the tubular body 20, and a packaging bag 70. Note that FIG. 3 is a cross-sectional view of a curved surface along line DD in FIG. 4.

[0019] As shown in FIG. 1 , the inserter 50 is a member that assists in the insertion of the guidewire 200 into the catheter. The inserter 50 is connected to one end of the tubular body 20 in the longitudinal direction. The inserter 50 is a tubular member made of resin that tapers in diameter toward the tip. Note that the container 10 does not necessarily have to have the inserter 50.

[0020] Each clip 60 is a resin member having a shape in which a plurality of clip recesses 61, into which the tube 20 fits, are arranged in parallel. By fitting the tube 20 into the clip recesses 61, the clips 60 fix the relative positions of adjacent portions of the tube 20, helping to maintain the wound shape of the tube 20. One or more clips 60 are provided along the winding direction of the tube 20.

[0021] The packaging bag 70 is a flexible, transparent resin bag that packs and seals the tubular body 20, the inserter 50, the clip 60, and the guidewire 200 together.

[0022] 1 to 4, the tubular body 20 is wound so as to be able to compactly house the long guidewire 200 and protect the housed guidewire 200 from bending and external impact. The tubular body 20 has a first end opening 21 located at one end in the longitudinal direction of the tubular body 20 and a second end opening 22 located at the other end. Therefore, when the guidewire 200 is in use, the guidewire 200 can be primed by passing physiological saline into the tubular body 20 from the first end opening 21 or the second end opening 22.

[0023] The length of the tube 20 in the longitudinal direction is not particularly limited, but is 150 mm to 500 mm. The inner diameter of the tube 20 is not particularly limited, but is 3 mm. The outer diameter of the tube 20 is not particularly limited, but is 4 mm.

[0024] The tube 20 has a bottom portion 30 having a side opening 23 extending from a first end opening 21 to a second end opening 22, and a lid portion 40 capable of covering the side opening 23. Both the bottom portion 30 and the lid portion 40 are spirally wound.

[0025] The lid portion 40 is formed with a size less than half the circumferential length of the tube body 20, preferably about one-quarter the size, in a cross section perpendicular to the longitudinal direction. The lid portion 40 has lid rim portions 41 located at both circumferential ends that contact the bottom portion 30, lid bodies 42 located between the two lid rim portions 41, and lid step portions 43 between each lid rim portion 41 and the lid body 42. The inner diameter of the lid rim portion 41 is larger than the inner diameter of the lid body 42. The inner diameter of the lid step portion 43 changes between the lid body 42 and the lid rim portion 41, and is the portion where the circumferential end face of the bottom portion 30 (bottom end face 34) abuts against the lid step portion 43.

[0026] The lid rim 41 has at least one claw 45 on its inner circumferential surface that protrudes radially inward. In this embodiment, the lid 40 has multiple claws 45 arranged along the longitudinal direction at intervals of approximately 50 mm, although this is not particularly limited. The length of each claw 45 along the longitudinal direction is approximately 2 mm, although this is not particularly limited. The thickness of the claw 45 in the radial direction of the tube body 20 is approximately 0.5 mm, although this is not particularly limited.

[0027] The bottom portion 30 is formed with a size exceeding half the circumference of the tubular body 20, preferably about three-quarters, in a cross section perpendicular to the longitudinal direction. This allows the bottom portion 30 to stably hold the guidewire 200 inside even after the lid portion 40 is removed. The bottom portion 30 has bottom edges 31 located at both circumferential ends that contact the lid portion 40, a bottom body 32 located between the two bottom edges 31, and bottom step portions 33 between each bottom edge 31 and the bottom body 32. The outer diameter of the bottom edge 31 is smaller than the outer diameter of the bottom body 32. The bottom step portions 33 are portions where the outer diameter changes between the bottom body 32 and the bottom edge 31, and where the circumferential end face of the lid portion 40 (lid end face 44) abuts against them.

[0028] The bottom edge portion 31 has at least one groove 35 on its outer circumferential surface and a limiting wall 36 located between the groove 35 and the bottom end face 34. In this embodiment, the grooves 35 include multiple grooves 35 arranged at intervals of approximately 50 mm along the longitudinal direction. Each groove 35 has an inlet portion 37 extending circumferentially from the bottom end face 34 and a groove body 38 extending from the inlet portion 37 in one direction along the longitudinal direction. The limiting wall 36 is located between the bottom end face 34 and the groove body 38 and extends along the longitudinal direction along the groove body 38. The inlet portion 37 is where the claws 45 of the lid portion 40 enter the groove 35. The groove body 38 is where the claws 45 entering the groove 35 can move in the longitudinal direction. The limiting wall 36 allows the claw 45 to slide when it enters the groove body 38, but also catches the claw 45, restricting the claw 45 from moving in the direction in which the lid portion 40 moves away from the bottom portion 30, i.e., restricting the claw 45 from leaving the groove body 38. The groove body 38 has a groove end portion 39 on the opposite side from the entrance portion 37, against which the claw 45 abuts to restrict the movement of the claw 45. Note that the groove body 38 may have a shape that does not have a groove end portion 39, but is shallower in depth to restrict the movement of the claw 45 in the longitudinal direction.

[0029] The length of each groove portion 35 along the longitudinal direction is not particularly limited, but is approximately 30 mm. Between two groove portions 35 adjacent in the longitudinal direction, there is a range where no groove portion 35 is formed. The length of the range where no groove portion 35 is formed along the longitudinal direction is not particularly limited, but is approximately 20 mm. The groove portions 35 are formed to a size that allows the claws 45 to move in the longitudinal direction. Therefore, the circumferential width of the groove body 38 is greater than the circumferential width of the claws 45. The longitudinal width of the inlet portion 37 is greater than the longitudinal width of the claws 45. The depth of the groove portion 35 is greater than the height of the claws 45.

[0030] Next, how to use the container 10 will be described. One longitudinal end of the tube 20 is inserted into and connected to the inserter 50. The tube 20 is formed by connecting a bottom portion 30 and a lid portion 40. That is, the lid portion 40 is placed over the side opening 23 of the bottom portion 30, and each of the claws 45 is inserted into each of the inlets 37 of the bottom portion 30, as shown in FIG. 5 . When the claws 45 reach the groove main body 38 and the lid portion end face 44 contacts the bottom step portion 33 and the bottom portion end face 34 contacts the lid step portion 43, the lid portion 40 moves in the longitudinal direction relative to the bottom portion 30 so that the claws 45 move toward the groove end portion 39. At this time, the lid portion end face 44 slides along the bottom step portion 33, and the bottom end face 34 slides along the lid step portion 43. As a result, as shown in Figure 4, all of the claws 45 are positioned in the groove body 38 and catch on the limiting wall 36, restricting all of the claws 45 from leaving the groove body 38. This connects the lid 40 to the bottom 30, maintaining the shape of the tubular body 20. As shown in Figure 1, a guidewire 200 is housed in the tubular body 20, and the tip of the guidewire 200 is inserted into the inserter 50. The tubular body 20, clip 60, inserter 50, and guidewire 200 housed in the tubular body 20 are packaged in a packaging bag 70.

[0031] Before using the guidewire 200, the surgeon takes out the tubular body 20 to which the clip 60 and the inserter 50 are connected from the packaging bag 70, and removes the inserter 50 from the tubular body 20. Next, the surgeon injects saline into the tubular body 20 from the first end opening 21 or the second end opening 22 to prime the guidewire 200 inside the tubular body 20.

[0032] Next, the surgeon rotates the lid portion 40 relative to the bottom portion 30 so that the lid portion 40 moves in the longitudinal direction of the tubular body 20 relative to the bottom portion 30. As a result, as shown in FIG. 5 , the claw 45 located at the groove end portion 39 of the groove body 38 moves to the entrance portion 37. Next, the surgeon moves the lid portion 40 in a direction away from the side opening 23. As a result, the claw 45 of the lid portion 40 moves through the entrance portion 37 and out of the groove portion 35, and the lid portion 40 is removed from the bottom portion 30. This allows the surgeon to remove the guidewire 200 in a wound and bundled state from the side opening 23 without pulling it out from the first end opening 21 or the second end opening 22 of the tubular body 20. This makes it easier for the surgeon to control the guidewire 200, preventing it from falling off the operating table. When removing the guide wire 200 from the side opening 23, the surgeon may invert the bottom portion 30 so that the side opening 23 faces downward.

[0033] As described above, the storage device 10 of the first embodiment is a storage device 10 having a spirally wound tubular body 20 that can store a long medical device (guide wire 200), and the tubular body 20 has a bottom 30 with a side opening 23 extending from a first end opening 21 located at both ends of the tubular body 20 in the longitudinal direction to a second end opening 22, and a lid portion 40 that can cover the side opening 23, one of the lid portion 40 and the bottom 30 has at least one claw 45 that can come into contact with the other, and the other has a limiting wall 36 formed along the longitudinal direction, slidable on the claw 45, and capable of limiting movement of the claw 45 in a direction away from the bottom 30, and by rotating the lid portion 40 along the longitudinal direction relative to the bottom 30, the claw 45 can be moved along the limiting wall 36, thereby attaching and detaching the bottom 30 and the lid portion 40. As a result, by removing the lid portion 40 from the bottom portion 30, the container 10 allows the long device to be removed from the side opening 23 of the bottom portion 30 while still in a wound state and bundled. This makes it easier to control the long device being removed and keep the long device in a sterile field. Furthermore, the operation of pulling the long device out from the first end opening 21 or the second end opening 22 of the tubular body 20 is not required. This prevents the outer peripheral surface of the long device from being damaged by rubbing against the edge of the first end opening 21 or the second end opening 22 of the tubular body 20. Therefore, if a hydrophilic coating is disposed on the outer peripheral surface of the long device, this prevents the hydrophilic coating from being damaged, which reduces the ease of insertion into a blood vessel and the operability of the device.

[0034] Second Embodiment As shown in FIG. 6, the container 10 according to the second embodiment differs from the first embodiment in that it has a shape maintaining member 46 for maintaining the rolled shape of the lid portion 40.

[0035] The lid portion 40 has an elongated shape-retaining member 46 that fits into a recess 47 formed in the outer peripheral surface of a resin lid body 42 and extending in the longitudinal direction. The shape-retaining member 46 is made of, for example, metal, but may be made of a material other than metal (e.g., engineering plastic) as long as it is harder than the material forming the lid body 42. The shape-retaining member 46 is formed in a wound shape in its natural state, when no external force is acting on it, before it is fixed to the lid body 42. The shape-retaining member 46 may be embedded inside the lid body 42 of the lid portion 40 when the lid body 42 is molded, or may be fixed to the outer or inner peripheral surface of the lid body 42.

[0036] As described above, in the container 10 according to the second embodiment, the lid 40 has a lid main body 42 made of resin, and a shape retention member 46 formed in a wound shape from a material harder than the lid main body 42 and fixed to the lid main body 42. This allows the shape retention member 46 to maintain the wound shape of the lid 40 even after it has been removed from the bottom part 30, making it easy to reattach it to the bottom part 30. Furthermore, the shape retention member 46 imparts rigidity to the lid 40 and can effectively transmit rotational force, making it easy to rotate the lid 40 when attaching or detaching it from the bottom part 30.

[0037] <Third embodiment> As shown in FIG. 7, the container 10 according to the third embodiment differs from the first and second embodiments in that the bottom portion 30 has a removable portion 81 that can be partially removed by an operator's operation.

[0038] As shown in FIG. 7(A), the bottom portion 30 has a plurality of removable portions 81 sandwiched between two rupturable breaking portions 80 in a portion of the longitudinal direction. The removable portions 81 are arranged at each of a plurality of locations on the wound bottom portion 30 that are aligned radially from the center of winding. The breaking portions 80 are, for example, perforations or grooves. The perforations are a structure in which a plurality of through-holes that penetrate the bottom portion 30 in the thickness direction are aligned.

[0039] When removing the guidewire 200 from the container 10, the surgeon breaks the multiple breaking portions 80 on the bottom portion 30 after removing the cover portion 40, as shown in FIG. 7(B). This allows the surgeon to remove all of the removal portions 81 that are aligned in the radial direction from the center of winding. This allows the surgeon to grasp the guidewire 200 exposed from the bottom portion 30 at the position where the removal portions 81 have been removed, while still bundled in a wound state, and remove it from the side opening 23 of the bottom portion 30.

[0040] As described above, in the container 10 according to the third embodiment, the bottom portion 30 has, in a part of its longitudinal direction, at least one removable portion 81 that is sandwiched between two breakable breaking portions 80. This allows the surgeon to easily remove the guidewire 200 exposed from the bottom portion 30 at the position where the removable portion 81 has been removed, from the side opening 23 of the bottom portion 30 while it is still bundled in a wound state.

[0041] <Fourth embodiment> As shown in FIGS. 8 and 9, the container 10 according to the fourth embodiment differs from the first to third embodiments in that it has a rotation assisting member 90 that makes it easier for the bottom part 30 and the lid part 40 to rotate relative to each other.

[0042] The rotation assist member 90 has at least one bottom clip 100 connected to the bottom portion 30 and at least one lid clip 110 connected to the lid portion 40. The bottom clip 100 has a plurality of bottom recesses 101 to which the bottom portion 30 is fitted and fixed, and two bottom sliding portions 102 located on both sides of the plurality of bottom recesses 101 and with which the lid clip 110 is in slidable contact. The lid clip 110 has a plurality of lid recesses 111 to which the lid portion 40 is fitted and fixed, and two lid sliding portions 112 located on both sides of the plurality of lid recesses 111 and with which the bottom clip 100 is in slidable contact. Each lid recess 111 has a connecting recess 121 into which a connecting protrusion 120 formed on the outer circumferential surface of the lid portion 40 is fitted. The bottom sliding portion 102 is a groove extending in the longitudinal direction of the tubular body 20, and the lid sliding portion 112 is a protrusion that slidably contacts the groove of the bottom sliding portion 102. Alternatively, the lid sliding portion 112 may be a groove extending in the longitudinal direction of the tubular body 20, and the bottom sliding portion 102 may be a protrusion that slidably contacts the groove of the lid sliding portion 112.

[0043] 9(A), in this embodiment, the cover recess 111 is a groove extending in the longitudinal direction of the tubular body 20, and the connecting protrusion 120 is a protrusion having a long apex (ridge) extending in the longitudinal direction and fitting into the cover recess 111. Alternatively, as in a modified example shown in FIG. 9(B), the connecting protrusion 120 may be formed in the cover recess 111 of the cover clip 110, and the connecting recess 121 may be formed on the outer peripheral surface of the cover 40.

[0044] The strength of the fit between the bottom recess 101 of the bottom clip 100 and the bottom 30 is greater than the strength (sliding resistance) of the fit between the lid 40 of the tube 20 and the bottom 30. As a result, when the lid 40 is moved in the longitudinal direction relative to the bottom 30, the position of the bottom clip 100 relative to the bottom 30 is maintained without shifting, and the force acting on the bottom clip 100 can be effectively applied to the bottom 30.

[0045] Furthermore, the strength of the fit between the connecting recess 121 and the connecting protrusion 120 is greater than the strength (sliding resistance) of the fit between the lid 40 and the bottom 30. As a result, when the lid 40 is moved in the longitudinal direction relative to the bottom 30, the position of the lid clip 110 relative to the lid 40 is maintained without shifting, and the force acting on the lid clip 110 can be effectively applied to the lid 40.

[0046] The lid 40 may have a plurality of connecting protrusions 120 (or connecting recesses 121) arranged at predetermined intervals in the longitudinal direction on its outer peripheral surface. The lid clip 110 has a connecting recess 121 into which one of the connecting protrusions 120 fits, and the connecting recess 121 may be formed in a hole shape rather than a groove shape so as to contact both ends in the longitudinal direction of the connecting protrusion 120. When fitting the lid 40 to the lid clip 110, the lid clip 110 can be fitted to the lid 40 by adjusting the positions of the connecting protrusions 120 formed on each turn of the wound lid 40 so that they are aligned in the radial direction from the center of the winding.

[0047] The lid 40 may have on its outer peripheral surface a plurality of hole-shaped connecting recesses 121 arranged at predetermined intervals in the longitudinal direction, instead of the connecting protrusions 120. In this case, the lid clip 110 has a connecting protrusion 120 that fits with one of the connecting recesses 121, and the connecting protrusion 120 is formed as a short protrusion in the longitudinal direction that can fit with the connecting recesses 121 so as to contact both ends in the longitudinal direction of the hole-shaped connecting recess 121.

[0048] 8 and 9, the surgeon supports one clip 60 (e.g., bottom clip 100) with one finger (e.g., index finger) and presses the other clip 60 (e.g., lid clip 110) with another finger (e.g., thumb) along the longitudinal axis of the tubular body 20. This allows the surgeon to rotate the lid portion 40 relative to the bottom portion 30 so that the lid portion 40 moves in the longitudinal axis direction of the tubular body 20 with respect to the bottom portion 30.

[0049] In the fourth embodiment, two pairs of lid clips 110 and bottom clips 100 are positioned on approximately opposite sides of the winding center of the tubular body 20. Therefore, the surgeon can easily rotate the lid clips 110 and bottom clips 100 on approximately opposite sides of the winding center of the tubular body 20 with their left and right hands, respectively, to attach and detach the bottom part 30 and the lid part 40.

[0050] As described above, the container 10 according to the fourth embodiment has a rotation assisting member 90 that can be connected to the bottom 30 or the lid 40. This makes it easy to rotate the container 10 when attaching or detaching the bottom 30 and the lid 40.

[0051] Furthermore, the rotation assist member 90 has at least one bottom clip 100 that can be connected to the bottom portion 30, and at least one lid clip 110 that can be connected to the lid portion 40. This allows the operator to easily attach and detach the bottom portion 30 and the lid portion 40 of the container 10 by supporting one clip 60 with a finger and pressing the other clip 60 along the longitudinal axis of the tubular body 20 with another finger.

[0052] Fifth Embodiment As shown in FIGS. 10 and 11, the container 10 according to the fifth embodiment differs from the fourth embodiment in the configuration of the rotation assisting member 90 that facilitates relative rotation of the bottom part 30 and the lid part 40.

[0053] The rotation assist member 90 has at least two lid clips 110 connected to the lid 40, a gripping portion 130 located near the center of the winding of the tubular body 20, and a plurality of connecting portions 131 connecting each of the lid clips 110 to the gripping portions 130. The lid clips 110, the gripping portions 130, and the connecting portions 131 are integrally molded, but they do not have to be integrally molded.

[0054] The lid clip 110 has a plurality of lid recesses 111 into which the lid 40 is fitted and fixed. As shown in FIG. 11(A), each lid recess 111 has a connecting recess 121 into which a connecting protrusion 120 formed on the outer peripheral surface of the lid 40 fits. Alternatively, as shown in a modified example in FIG. 11(B), the connecting protrusion 120 may be formed in the lid recess 111 of the lid clip 110, and the connecting recess 121 may be formed on the outer peripheral surface of the lid 40. The structures of the connecting protrusions 120 and the connecting recess 121 may be the same as those in the fourth embodiment.

[0055] The gripping portion 130 is a portion that the surgeon grasps in order to apply a rotational force to the lid 40 via the lid clips 110. The shape of the gripping portion 130 is not particularly limited as long as it can be grasped by the surgeon. The gripping portion 130 is preferably positioned near the center of the winding of the tubular body 20 so that the surgeon can apply a rotational force evenly to the multiple lid clips 110, but it does not have to be positioned near the center of the winding as long as it is positioned closer to the center of the winding of the tubular body 20 than the tubular body 20.

[0056] Each connecting portion 131 extends from the gripping portion 130 to one of the lid clips 110 and connects the gripping portion 130 and the lid clip 110 together.

[0057] When removing the guidewire 200 from the container 10 shown in FIGS. 10 and 11 , the surgeon supports the bottom portion 30 or the clip 60 with one hand, while gripping the gripping portion 130 with the other hand to rotate the lid portion 40. By simply rotating the gripping portion 130, the surgeon can apply a substantially uniform force to the multiple lid clips 110 collectively, thereby efficiently rotating the lid portion 40. This causes the lid portion 40 to move in the longitudinal direction of the tubular body 20 relative to the bottom portion 30, and the lid portion 40 to rotate relative to the bottom portion 30. Therefore, the surgeon can easily attach and detach the bottom portion 30 and the lid portion 40.

[0058] As described above, in the container 10 according to the fifth embodiment, the rotation assist member 90 has a plurality of lid clips 110 that secure the lid 40, a gripping portion 130 that is disposed toward the center of the winding of the tubular body 20, and a connecting portion 131 that connects each lid clip 110 to the gripping portion 130. This allows the surgeon to grasp the gripping portion 130, facilitating the rotation operation when attaching or detaching the bottom portion 30 and the lid 40.

[0059] The present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art within the technical spirit of the present invention. For example, the elongated medical device housed in the housing 10 is not limited to the guidewire 200, but may be, for example, a catheter. Furthermore, the bottom 30 may be formed with a claw 45, and the lid 40 may be formed with a groove 35. Furthermore, if the limiting wall 36 is present, the groove 35 is not necessarily required.
