Description

Technical Field

[0001] The present invention relates to a clip for bundling and holding long medical devices.

Background Art

[0002] In endovascular treatment, an operator may remove long medical devices such as guidewires and catheters outside the body during a procedure and then insert them back into the blood vessel again. The long medical devices removed outside the body need to be stored in a limited space on a clean procedure table. In addition, long medical devices with a hydrophilic coating on their outer surfaces need to maintain a state where their outer surfaces are wet with water during storage. For this reason, long medical devices temporarily removed outside the body during a procedure are held in a state of being bundled and rotated multiple times in a bath filled with water.

[0003] When a long medical device has high elasticity, the long medical device tends to return from the bundled state to its original straight state. Therefore, means for temporarily holding the long medical device in a bundled state are necessary. For example, in Patent Document 1, a device (hereinafter referred to as a clip) for firmly and gently holding a flexible long medical device has been proposed. This clip has a hinged opening and closing structure, and a flexible material is arranged on the contact surface with the long medical device so that the long medical device can be held without being damaged.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When a long device with a hydrophilic coating on its outer surface is held by the aforementioned clip and stored in a water-filled tub, the frictional resistance of the contact surface between the clip and the long device decreases, reducing the clip's ability to hold the device. As a result, the long device may return to its straightened state and fall out of the tub. In other words, the aforementioned clip cannot reliably prevent the long device from falling into an unclean area.

[0006] This invention was made to solve the above-mentioned problems, and aims to provide a clip that can firmly hold a bundle of long medical devices that have been wrapped around multiple times. [Means for solving the problem]

[0007] The clip according to the present invention, which achieves the above objective, can hold a bundle of flexible, elongated medical devices that have been wrapped around multiple times, and is a flat plate-shaped clip having a front surface, a back surface and a side surface, and comprises a frame surrounding an opening that penetrates in the thickness direction perpendicular to the front surface, and a projection that protrudes from the frame inward into the opening, wherein the frame comprises an upper frame to which the projection is connected, a lower frame positioned on the opposite side of the upper frame across the opening, and two lateral frames positioned between the upper frame and the lower frame and sandwiching the opening, and each of the lateral frames has a groove on the back surface that extends from the opening side to the side surface and includes an upper inner wall surface on the side closer to the upper frame, a lower inner wall surface on the side closer to the lower frame, and a bottom surface positioned between the upper inner wall surface and the lower inner wall surface, and the tip of the projection, which is the end of the projection on the side in the direction of protrusion, is located below the lower inner wall surfaces of the two grooves formed in each of the lateral frames, in the direction from the upper frame to the lower frame. [Effects of the Invention]

[0008] The clip configured as described above can firmly hold the convergent object by sandwiching it between the two grooves and the surface of the protrusions formed on each frame.

[0009] The direction from the back surface toward the front surface is defined as the height direction, and the direction from the front surface toward the back surface is defined as the depth direction. The surface of the highest part of the projection, which is the part of the projection that is highest in the height direction from the back surface, may be positioned in the thickness direction toward the depth direction than the surface of the frame. This allows the clip to guide the condenser between the back surface of the frame and the surface of the projection. Furthermore, the operator can intuitively understand that the condenser is to be inserted between the surface of the projection and the back surface of the frame. In addition, when attaching the clip to the condenser, the operator can easily visually confirm that the insertion of the condenser into the clip is complete because the condenser will abut against the upper opening when pushed upward.

[0010] The surface of the highest point of the projection may be positioned in the thickness direction to coincide with the bottom surface of the groove. This allows the clip to firmly hold the bundled object by gripping it at three locations: the two grooves and the projection formed on each side frame.

[0011] The upper inner wall surface of the groove of each of the lateral frames may be arranged on the same plane as the upper opening surface, with the upper opening surface forming the upper side surface of the inner wall surface of the opening in between. This allows the clip to stably hold the condenser because the condenser contacts the two upper inner wall surfaces and the upper opening surface of each groove when the clip holds it. Furthermore, when attaching the clip to the condenser, the operator can easily confirm that the condenser is housed in the groove, even from the surface side of the clip. This prevents the operator from pushing the condenser further into the groove than necessary, thus preventing damage to the long device and peeling of the coating.

[0012] The lower inner wall surface of the groove of at least one of the lateral frames may have a notch on the lateral side. This allows the clip to easily attach to and detach from the bundle by moving the bundle along the surface of the outer notch.

[0013] The aforementioned notches form a set of notches consisting of an outer notch formed on the side surface of the lower inner wall surface of one of the lateral frames and an inner notch formed on the opening side of the lower inner wall surface of the other lateral frame, and the clip may be provided with at least one set of notches. This makes it possible to prevent the bundle from getting caught on the lower inner wall surface of the groove by tilting the clip relative to the bundle when attaching or detaching the clip to the bundle.

[0014] The area of ​​the outer notch may be greater than or equal to the area of ​​the inner notch. By making the area of ​​the outer notch greater than or equal to the area of ​​the inner notch, the clip can firmly hold the bundle while improving the ease of attachment and detachment to the bundle.

[0015] The lower inner wall surface of the groove may have a parallel portion between the opening side and the side surface that is parallel to the upper inner wall surface when viewed from the back side in the thickness direction. This prevents the clip from causing the bundled object housed in the groove to fall out in the depth direction, thus ensuring that the bundled object is securely housed in the groove.

[0016] The back surface of the projection may be positioned further in the depth direction from the front surface towards the back surface than the back surface of the frame. This ensures that the thickness of the projection is maintained even if the surface of the projection is positioned further in the depth direction than the surface of the frame, thereby preventing damage to the projection.

[0017] The direction from the surface to the back surface is defined as the depth direction, and the surface of the projection may have a central part of the projection which is flat, and an inclined part which slopes toward the depth direction as it extends from the central part of the projection toward the lateral frame. By having an inclined part in the projection, the clip can increase the radius of curvature of the convergent body extending between the central part of the projection and the groove compared to the case where there is no inclined part. As a result, the clip can reduce the load on the long device, and thus can suppress damage to the long device.

[0018] The protrusion has a protrusion base connected to the upper frame and including a protrusion central portion and the inclined portions, and a protrusion end portion formed on the protruding direction side of the protrusion base. The surface of the protrusion end portion and the surface of the protrusion central portion of the protrusion base are smoothly connected, and a protrusion step portion may be formed between the surface of the protrusion end portion and the surfaces of the two inclined portions of the protrusion base. Thereby, the clip improves the operability of attaching and detaching the clip to / from the aggregate by the smooth connection between the surface of the protrusion end portion and the surface of the protrusion central portion of the protrusion base, and can firmly hold the aggregate by the protrusion step portion formed between the surface of the protrusion end portion and the surface of the inclined portion.

[0019] The frame may have an additional frame disposed on the opposite side of the protruding direction of the protrusion with respect to the upper frame, and an additional opening penetrating in the thickness direction between the additional frame and the upper frame. Thereby, the clip can be bundled in an individual package for accommodating a long device by fitting the additional frame to, for example, a holder clip or the like. Also, since the clip can grip the additional frame during use, the operability of attaching and detaching the clip to / from the aggregate is improved.

Mode for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the dimensional ratios in the drawings may be exaggerated for convenience of explanation and may differ from the actual ratios. Also, the expressions "upper", "lower", "vertical", and "horizontal" in this specification are used for convenience of explanation and do not limit the posture of the clip.

[0022] As shown in FIG. 9, the clip 10 according to the present embodiment is used to hold a bundled body 101 formed by winding a plurality of medical elongated devices 100 such as guide wires and catheters. As shown in FIG. 7, the clip 10 is connected via a holder clip 130 to a tubular holder tube 120 (container) wound for the purpose of storing and transporting the elongated device 100 while protecting it, and is packaged in a storage bag 140 together with the holder tube 120, the elongated device 100, and the holder clip 130. Note that the clip 10 may not be packaged in the storage bag 140.

[0023] As shown in Figures 1-2, the clip 10 is a flat, plate-shaped device having a front surface 11, a back surface 12, and a side surface 13. The clip 10 is formed thinly between the substantially parallel front surface 11 and back surface 12. By forming the clip 10 in a thin, flat shape, it can be included in a thin storage bag 140 for individually packaging the long device 100. Furthermore, even when the clip 10 is included in the storage bag 140 of the long device 100, it does not protrude from the surface of the storage bag 140, thus reducing the likelihood of contamination of the long device 100 due to damage to the storage bag 140 during storage or transport.

[0024] Clip 10 is formed from a resin such as polypropylene, polyethylene, polystyrene, polyethylene terephthalate, polycarbonate, or polyvinyl chloride resin.

[0025] The clip 10 has a frame 20 with an opening 21 and an additional opening 22 that penetrate in the thickness direction X perpendicular to the surface 11 and / or back surface 12, and a projection 30 that protrudes from the frame 20 inward into the opening 21. The direction perpendicular to the thickness direction X and parallel to the projection direction of the projection 30 is defined as the vertical direction Y, and the direction perpendicular to the thickness direction X and the vertical direction Y is defined as the horizontal direction Z. The total width A of the clip 10 in the horizontal direction Z is 10 mm or more and 200 mm or less. The total length B of the clip 10 in the vertical direction is 10 mm or more and 200 mm or less. The frame 20 is formed with a substantially constant thickness T. The thickness T of the frame 20 in the thickness direction X is preferably 0.5 mm or more and 20.0 mm or less.

[0026] The frame 20 comprises an upper frame 40 to which the projection 30 is connected, a lower frame 50, two lateral frames 60 positioned between the upper frame 40 and the lower frame 50 and sandwiching the opening 21, and an additional frame 80 positioned on the opposite side of the direction in which the projection 30 protrudes relative to the upper frame 40.

[0027] The upper frame 40 has an upper opening surface 41 that forms the upper side of the inner wall surface of the opening 21. "Upper" refers to the direction from the lower frame 50 to the upper frame 40 in the vertical direction Y. The upper opening surface 41 is perpendicular to the vertical direction Y and extends parallel to the horizontal direction Z between the two lateral frames 60. The upper opening surface 41 is a plane to which the converging body 101 can make contact.

[0028] The lower frame 50 is positioned on the opposite side of the upper frame 40, with the opening 21 in between, and is curved in an arc shape that is convex downwards. Downward refers to the direction from the upper frame 40 to the lower frame 50 in the vertical direction Y. The lower frame 50 has a lower opening surface 51 that forms the lower side of the inner wall surface of the opening 21. The lower opening surface 51 is curved to be concave and faces the upper opening surface 41.

[0029] The two lateral frames 60 are positioned between the upper frame 40 and the lower frame 50, sandwiching the opening 21. Each lateral frame 60 has a lateral opening surface 61 that forms the lateral surface of the inner wall surface of the opening 21, and a groove 62 for accommodating the converging body 101. Lateral refers to the direction from the opening 21 to the side surface 13 in the lateral direction Z. Each groove 62 extends from the opening 21 side to the side surface 13 side on the back surface 12 of the lateral frame 60. The two grooves 62 are formed symmetrically, but are not limited to this. The clip 10 can firmly hold the converging body 101 by sandwiching it at three locations: the two grooves 62 formed on each lateral frame 60 and the surface 11 of the projection 30.

[0030] Each groove 62, as shown in Figures 3-4, comprises an upper inner wall surface 63 on the side closer to the upper frame 40, a lower inner wall surface 64 on the side closer to the lower frame 50, and a bottom surface 65 positioned between the upper inner wall surface 63 and the lower inner wall surface 64. The condensing body 101 housed in the groove 62 contacts the bottom surface 65 of the groove 62. Therefore, the clip 10 can hold the condensing body 101 by clamping it at three locations: the bottom surfaces 65 of the two grooves 62 formed in each side frame 60 and the surface 11 of the projection 30.

[0031] Each upper inner wall surface 63 is a continuous surface extending laterally from the upper opening surface 41. The two upper inner wall surfaces 63 are positioned on the same plane as the upper opening surface 41, with the upper opening surface 41 in between. As a result, when the clip 10 holds the focusing body 101, the focusing body 101 comes into contact with the two upper inner wall surfaces 63 of each groove 62 and the upper opening surface 41, allowing the clip 10 to stably hold the focusing body 101. Also, when the surgeon attaches the clip 10 to the focusing body 101, they push the focusing body 101 upward. If the surgeon attaches the clip 10 to the focusing body 101 while looking at the surface 11 of the clip 10, the surgeon cannot confirm that the focusing body 101 is housed in the groove 62 located on the back surface 12. Therefore, if the operator pushes the focusing body 101 too far upward, the focusing body 101 may come into contact with the corner of the upper inner wall surface 63 of the groove 62 on the opening 21 side, potentially causing damage to the long device 100 or peeling of the coating. Since the two upper inner wall surfaces 63 are positioned on the same plane as the upper opening surface 41, with the upper opening surface 41 in between, the operator can easily confirm that the focusing body 101 is housed in the groove 62, even from the surface 11 side of the clip 10. As a result, the operator will not push the focusing body 101 further upward in the groove 62 than necessary, and the clip 10 can suppress damage to the long device 100 and peeling of the coating.

[0032] Each lower inner wall surface 64 has an inner notch 66 on the opening 21 side, an outer notch 67 on the side surface 13 side, and a lower intermediate surface 68 between the inner notch 66 and the outer notch 67. The lower intermediate surface 68 includes a parallel portion 69 that is parallel to the upper inner wall surface 63 when viewed in the thickness direction X from the back surface 12 side.

[0033] The outer notch 67 is a portion having a roughly triangular plane formed by beveling the corner on the side surface 13 of the lower inner wall surface 64. The inner notch 66 is a portion having a roughly triangular plane formed by beveling the corner on the opening 21 of the lower inner wall surface 64. The shape of the outer notch 67 and the inner notch 66 may be a convex curved surface by beveling the corners on the side surface 13 and the opening 21 of the lower inner wall surface 64 so that they are rounded. The outer notch 67 and the inner notch 66 prevent the bundle 101 from getting caught on the lower inner wall surface 64 of the groove 62 when attaching and detaching the clip 10 to the bundle 101. In particular, the outer notch 67 allows for easy attachment and detachment of the clip 10 to and from the bundle 101 by moving the bundle 101 along the surface of the outer notch 67. The outer notch 67 and the inner notch 66 improve the operability of attaching and detaching the clip 10 to and from the bundle 101, and also suppress damage to the long device 100 and peeling of the coating.

[0034] The outer notch 67 of one side frame 60 and the inner notch 66 of the other side frame 60 form a set of notches. This prevents the converging body 101 from getting caught on the lower inner wall surface 64 of the groove 62 by tilting the clip 10 relative to the converging body 101 when attaching or detaching the clip 10 to the converging body 101. In other words, when the lateral direction Z of the clip 10 is tilted relative to the converging body 101, the converging body 101 comes into contact with the corner on the side surface 13 side of the lower inner wall surface 64 of one side frame 60 and the corner on the opening 21 side of the lower inner wall surface 64 of the other side frame 60. Therefore, the clip 10 has a set of notches formed by an outer notch 67 on one side frame 60 of the clip 10 and an inner notch 66 on the other side frame 60, which prevents the condenser 101 from getting caught on the lower inner wall surface 64 of the groove 62 when attaching or detaching the clip 10 to the condenser 101. In this embodiment, the clip 10 has two sets of notches. This improves the operability of attaching and detaching the clip 10 to the condenser 101, regardless of the direction in which the lateral Z of the clip 10 is tilted relative to the condenser 101. Note that, as shown in the modified example in Figure 6, the clip 10 may have only one set of notches.

[0035] The surfaces 11 of the outer notch 67 and / or inner notch 66 connect smoothly to the bottom surface 65. By eliminating the step between the outer notch 67 and inner notch 66 and the bottom surface 65, the clip 10 can prevent the bundle 101 from getting caught in the groove 62 when attaching or detaching it from the bundle 101, thereby improving operability.

[0036] The area of ​​the outer notch 67 is greater than or equal to the area of ​​the inner notch 66. Preferably, the area of ​​the outer notch 67 is larger than the area of ​​the inner notch 66. If the outer notch 67 and the inner notch 66 are formed as convex curved surfaces, the radius of curvature of the outer notch 67 is greater than or equal to the radius of curvature of the inner notch 66. The outer notch 67 is the corner of the lower inner wall surface 64 that first comes into contact with the condenser 101 when attaching or detaching the clip 10 to the condenser 101. In addition, the outer notch 67 comes into stronger contact with the condenser 101 than the inner notch 66 when attaching or detaching the clip 10 to the condenser 101. Therefore, by increasing the area of ​​the outer notch 67, the clip 10 can effectively prevent the bundled body 101 from getting caught on the lower inner wall surface 64 of the groove 62 when attaching or detaching the clip 10 to the bundled body 101. On the other hand, the inner notch 66 is a part that affects the holding force of the clip 10 on the bundled body 101. The bundled body 101 housed in the groove 62 of the clip 10 makes stronger contact with the opening 21 side than with the side surface 13 side at the bottom surface 65 of the groove 62. For this reason, if the area of ​​the inner notch 66 is too large, the bundled body 101 will be more likely to fall out of the groove 62. By making the area of ​​the outer notch 67 greater than the area of ​​the inner notch 66, the clip 10 can firmly hold the bundled body 101 while improving the operability of attaching and detaching it to the bundled body 101.

[0037] The length A1 of the outer notch 67 in the lateral direction Z is preferably greater than or equal to the length A2 of the inner notch 66 in the lateral direction Z. Also, the length B1 of the outer notch 67 in the vertical direction Y is preferably greater than or equal to the length B2 of the inner notch 66 in the vertical direction.

[0038] The sum of the lateral Z length A1 of the outer notch 67 and the lateral Z length A2 of the inner notch 66 is less than the lateral Z length L of the portion of the lateral frame 60 where the groove 62 is formed. That is, at the lower inner wall surface 64 of the groove 62, the outer notch 67 on the side surface 13 and the inner notch 66 on the opening 21 side are not directly connected, but are connected via the lower intermediate surface 68. The surfaces 11 of the outer notch 67 and / or the inner notch 66 connect smoothly with the lower intermediate surface 68.

[0039] The cross-section of the lower intermediate surface 68 perpendicular to the lateral direction Z is preferably approximately S-shaped. The lower intermediate surface 68 has a convex curved surface 70 that connects to the back surface 12 of the lateral frame 60 located below the groove 62, and a concave curved surface 71 that connects to the bottom surface 65 of the groove 62. The presence of the concave curved surface 71 on the lower intermediate surface 68 allows the condenser 101 to be stably held in the groove 62. Furthermore, on the lateral frame 60, the back surface 12, the convex curved surface 70, the concave curved surface 71, and the bottom surface 65 are smoothly connected in order from top to bottom, thus preventing the condenser 101 from getting caught in the groove 62 when attaching or detaching the clip 10 to the condenser 101. As a result, the operability of attaching and detaching the clip 10 to the condenser 101 is improved, and damage to the long device 100 and peeling of the coating can be suppressed.

[0040] The lower intermediate surface 68 includes a parallel portion 69 between the convex curved surface 70 and the concave curved surface 71 of the lower intermediate surface 68, which is parallel to the upper inner wall surface 63 when viewed from the back surface 12 side in the thickness direction X. The parallel portion 69 is positioned to connect the outer notch 67 and the inner notch 66 on the opening 21 side. The parallel portion 69 prevents the bundled body 101 housed in the groove 62 from falling out in the depth direction X1. The depth direction X1 is the direction from the surface 11 to the back surface 12 in the thickness direction X. As a result, the clip 10 can securely house the bundled body 101 in the groove 62.

[0041] The bottom surface 65 of each groove 62 is formed from the back surface 12 in the thickness direction X to a predetermined depth D1, as shown in Figure 1(C). The depth D1 of the groove 62 is set according to the outer diameter of the elongated device 100 so that the elongated device 100 to be housed does not fall out. The depth D1 of the groove 62 is 0.1 mm or more and 15.0 mm or less. As shown in Figures 1(B) and 3, the length L in the lateral direction Z of the groove 62 is 1 mm or more and 50 mm or less. The minimum distance W in the vertical direction Y of the groove 62 is 1 mm or more and 100 mm or less. The minimum distance W in the vertical direction Y of the groove 62 is the distance in the vertical direction Y between the lowest part of the upper inner wall surface 63 and the highest part of the lower inner wall surface 64. Preferably, the minimum distance W is greater than or equal to the width of the condenser 101 so that the condenser 101 can be housed in the groove 62.

[0042] As shown in Figures 1 and 2, the additional frame 80 is positioned above the upper frame 40. An additional opening 22 is formed between the additional frame 80 and the upper frame 40, penetrating in the thickness direction X. The additional frame 80 has a connecting portion 81 that can be connected to the holder clip 130, and support frames 82 positioned on both sides of the connecting portion 81.

[0043] The connecting portion 81 is formed in a cylindrical shape. The outer diameter of the connecting portion 81 is approximately equal to the outer diameter of the holder tube 120, which is 5 mm. The clip 10 can be connected to the holder clip 130 by fitting the connecting portion 81 into one of the recesses 131 of the holder clip 130. The structure of the connecting portion 81 is not particularly limited as long as it can be connected to the holder clip 130, the holder tube 120, or other structures inside the storage bag 140. For example, the connecting portion of the clip 10 may be cylindrical with a through-hole. In this case, the inner diameter of the connecting portion is approximately equal to the outer diameter of the holder tube 120, or slightly larger than the outer diameter of the holder tube 120. The clip 10 can be connected to the holder tube 120 by inserting the holder tube 120 through the cylindrical lumen of the connecting portion. The connecting portion may have a slit extending between the openings at both ends in the side wall of the cylinder. As a result, the connecting portion allows the holder tube 120 to be inserted into the lumen of the cylinder through a slit in the side wall of the cylinder, making it easy to connect the clip 10 to the holder tube 120.

[0044] The support frame 82 gradually curves downward while extending laterally from both ends of the connecting portion 81 and is connected to the upper end of the lateral frame 60. An additional groove 83 is formed on the surface 11 of each support frame 82, extending from the additional opening 22 to the side surface 13. It is preferable that the two additional grooves 83 are formed symmetrically. The depth D2 of the additional groove 83 is 0.1 mm or more and 15 mm or less.

[0045] As shown in Figures 1-2 and 5, the projection 30 protrudes downward from the upper opening surface 41 of the upper frame 40. The projection 30 protrudes to a length that does not reach the lower frame 50. The projection tip 39, which is the end of the projection 30 on the protruding side, is located below the lower inner wall surface 64 of the two grooves 62 formed in each of the side frames 60, as shown in Figure 1(B). As a result, the clip 10 can grip the converging body 101 at three locations: the two grooves 62 formed in each of the side frames 60 and the projection 30, thereby firmly holding the converging body 101.

[0046] The back surface 12 of the projection 30 is positioned X1 in the depth direction relative to the back surface 12 of the frame 20. This ensures that the clip 10 can maintain the thickness of the projection 30 even if the front surface 11 of the projection 30 is positioned X1 in the depth direction relative to the front surface 11 of the frame 20, thereby preventing damage to the projection 30.

[0047] The surface 11 of the projection 30 has a projection base 32 connected to the upper frame 40 and a projection end 33 formed on the side of the projection 30 that is further out than the projection base 32. The projection base 32 has a flat projection central portion 34 and two inclined portions 35 extending to both sides from the projection central portion 34. The projection central portion 34 includes the projection highest portion 31, which is the part of the projection 30 that is highest in the height direction X2 from the back surface 12. The height direction X2 is the direction from the back surface 12 to the front surface 11 in the thickness direction X. In this embodiment, the projection central portion 34 is a plane parallel to the surface 11 of the upper frame 40 and coincides with the projection highest portion 31.

[0048] The surface 11 of the highest point 31 of the projection is positioned in the thickness direction X, closer to the depth direction X1 than the surface 11 of the frame 20. This allows the clip 10 to guide the long device 100 between the back surface 12 of the frame 20 and the surface 11 of the projection 30. Furthermore, because the surface 11 of the highest point 31 of the projection is positioned in the thickness direction X, closer to the depth direction X1 than the surface 11 of the frame 20, a step portion 38 is formed between the surface 11 of the highest point 31 of the projection and the surface 11 of the upper frame 40 by a part of the upper opening surface 41. This allows the operator to intuitively understand that the focusing body 101 should be inserted between the surface 11 of the projection 30 and the back surface 12 of the frame 20. Moreover, when attaching the clip 10 to the focusing body 101, if the operator pushes the focusing body 101 upward, the focusing body 101 will abut against the upper opening surface 41 at the step portion 38. Therefore, the operator can easily visually confirm that the insertion of the focusing body 101 into the clip 10 is complete. The surface 11 of the highest point 31 of the protrusion may be positioned at the same location as the surface 11 of the frame 20 in the thickness direction X.

[0049] It is preferable that the surface 11 of the highest point 31 of the projection is positioned in the thickness direction X to substantially coincide with the bottom surface 65 of the groove 62. This allows the clip 10 to grip the bundled body 101 at three locations: the two grooves 62 and the projection 30 formed in each side frame 60, thereby firmly holding the bundled body 101. Alternatively, the surface 11 of the highest point 31 of the projection may be positioned in the thickness direction X1 closer to the depth direction X1 than the bottom surface 65 of the groove 62. In this case, it is preferable that the distance between the surface 11 of the highest point 31 of the projection and the bottom surface 65 of the groove 62 in the thickness direction X is less than the maximum outer diameter of the elongated device 100. This allows the clip 10 to grip the bundled body 101 at three locations: the two grooves 62 and the projection 30 formed in each side frame 60.

[0050] Each inclined portion 35 provided on the projection base 32 is inclined in the depth direction X1 as it extends laterally. The inclination angle of the inclined portion 35 in the depth direction X1 may be constant as it extends laterally, or it may increase as it extends laterally. The length of the inclined portion 35 in the vertical direction Y is approximately equal to the minimum distance W of the groove 62 in the vertical direction Y. By having the projection 30 have the inclined portion 35, the clip 10 can increase the radius of curvature of the portion extending between the central portion 34 of the projection of the long device 100 and the groove 62 compared to the case where the inclined portion 35 is not present. As a result, the clip 10 can reduce the load on the long device 100, thereby suppressing damage to the long device 100.

[0051] The projection end portion 33 has a projection-side inclined portion 36 that slopes in the depth direction X1 as it extends from the projection center portion 34 toward the projection direction of the projection 30. The inclination angle of the projection-side inclined portion 36 toward the depth direction X1 may be constant toward the projection direction, but may increase toward the projection direction. The surface 11 of the projection end portion 33 and the surface 11 of the projection center portion 34 of the projection base portion 32 are smoothly connected. In contrast, a projection step portion 37 is formed between the surface 11 of the projection end portion 33 and the surfaces 11 of the two inclined portions 35 of the projection base portion 32, as the inclined portions 35 slope toward the depth direction X1 as they extend laterally. The surface 11 of the projection end 33 and the surface 11 of the projection center 34 of the projection base 32 of the clip 10 are smoothly connected, improving the ease of attaching and detaching the clip 10 to the bundle 101, while the projection step 37 formed between the surface 11 of the projection end 33 and the surface 11 of the inclined portion 35 allows the bundle 101 to be firmly held.

[0052] The width S of the projection 30 in the lateral direction Z is 5 mm or more and 80 mm or less. The projection thickness PT of the projection 30 from the back surface 12 of the frame 20 in the depth direction X1 is preferably 0.5 mm or more and 10 mm or less, and more preferably 1.0 mm.

[0053] Next, the method of use of the clip 10 will be described along with its operation and effects. As shown in Figure 7, the clip 10 is provided individually packaged in a storage bag 140 together with a holder tube 120 that holds a long medical device 100 such as a guidewire or catheter. The holder tube 120 is held in a wound state by a holder clip 130 which has a plurality of recesses 131 arranged in a row that can be fitted and held by the tube. The clip 10 is connected to the holder clip 130 by fitting its connecting portion 81 into one of the innermost recesses 131 of the holder clip 130 that holds the holder tube 120.

[0054] During an endovascular procedure, the surgeon may remove the long device 100 from the body and temporarily store it for reinsertion. The surgeon uses a clip 10 to hold the bundled long device 100 after it has been removed from the blood vessel. As shown in Figure 8(A), the surgeon holds the bundled body 101, which is made by wrapping the long device 100 around it multiple times, with one hand and the clip 10 with the other hand, and while looking at the surface 11 of the clip 10, brings the back surface 12 of the lower frame 50 into contact with the bundled body 101. At this time, the surgeon may also bring the back surface 12 of the lateral frame 60 into contact with the bundled body 101.

[0055] The clip 10 has an additional groove 83 formed on the surface 11 of the additional frame 80. This guides the operator to place their thumb on the additional groove 83, allowing them to intuitively grasp the clip 10 with its surface 11 facing forward. The presence of the additional groove 83 facilitates the operator's proper use of the clip 10. Two additional grooves 83 are symmetrically positioned on both support frames 82. Therefore, the operator can easily use the clip 10 with either their left or right hand.

[0056] The clip 10 has a set of notches formed by an outer notch 67 on one side frame 60 of the clip 10 and an inner notch 66 on the other side frame 60. As a result, as shown in Figure 8(A), the surgeon can tilt the clip 10 in the lateral direction Z with respect to the extending direction of the focusing body 101, so that the outer notch 67 is closer to the focusing body 101, making it less likely for the focusing body 101 to get caught on the lower inner wall surface 64 of the groove 62, and making it easier to insert the focusing body 101 between the frame 20 and the projection 30.

[0057] Next, as shown in Figures 8(B), 9, and 10, the operator moves the back surfaces 12 of the lower frame 50 and the lateral frame 60 along the focusing body 101, pushing the focusing body 101 into the clip 10 so that it is sandwiched between the surface 11 of the projection 30 and the back surfaces 12 of the two lateral frames 60. The clip 10 can guide the focusing body 101 to the surface 11 of the projection 30 by moving the focusing body 101 along the back surface 12 of the lower frame 50. In addition, because the surface 11 of the projection 30 is located on the depth X side compared to the surface 11 of the frame 20, the clip 10 can guide the focusing body 101 between the back surface 12 of the frame 20 and the surface 11 of the projection 30. As a result, the clip 10 improves the insertability of the focusing body 101 and encourages the operator to use the clip 10 appropriately.

[0058] Furthermore, the clip 10 has a protruding-side inclined portion 36 formed on the protruding side of the surface 11 of the projection 30. This makes it easy for the surgeon to insert the focusing body 101 between the back surface 12 of the frame 20 and the surface 11 of the projection 30. Because the surface of the protruding-side inclined portion 36 and the surface of the projection center portion 34 are smoothly connected, the surgeon can easily move the focusing body 101 along the surface 11 of the projection 30, from the protruding-side inclined portion 36 through the projection center portion 34 to the upper opening surface 41.

[0059] As the condenser 101 moves until it contacts the upper opening surface 41, it is housed in two grooves 62 provided in the two lateral frames 60, as shown in Figures 8(B), 9, and 10, and contacts the central portion 34 and / or inclined portion 35 of the projection 30. The clip 10 can hold the condenser 101 by clamping it at three points: the two grooves 62 formed in each lateral frame 60 and the surface 11 of the projection 30.

[0060] When the clip 10 holds the bundled body 101, the bundled body 101 is housed between the upper inner wall surface 63 and the lower inner wall surface 64 of each groove 62. The lower inner wall surface 64 has a substantially S-shaped lower intermediate surface 68, a parallel portion 69 parallel to the upper inner wall surface 63, and a concave curved surface 71. As a result, the clip 10 can stably and firmly hold the bundled body 101 between the upper inner wall surface 63 and the lower inner wall surface 64. Furthermore, the clip 10 can prevent the bundled body 101 from getting caught in the groove 62 when attaching or detaching it. As a result, the clip 10 can improve operability and prevent damage to the long device 100 and peeling of the coating.

[0061] The projection 30 of the clip 10 is provided with an inclined portion 35. By having the projection 30 have an inclined portion 35, the clip 10 can increase the radius of curvature of the portion extending between the central part 34 of the projection 30 and the groove 62 of the elongated device 100 compared to the case where the projection 30 does not have an inclined portion 35. As a result, the clip 10 can reduce the load on the elongated device 100, thereby suppressing damage to the elongated device 100. Furthermore, the inclined portion 35 forms a projection step portion 37 between the surface of the projection end portion 33 and the surface of the inclined portion 35 of the projection base portion 32. The projection step portion 37 can prevent the bundled body 101 from unintentionally coming off in the direction of the projection 30 when the clip 10 is holding the bundled body 101.

[0062] The clip 10 has a projection 30 whose surface 11 is positioned further to the depth X side than the surface 11 of the frame 20, and a stepped portion 38 is formed between the surface 11 of the central part 34 of the projection and the surface 11 of the upper frame 40. The stepped portion 38 prevents the condensing body 101 from unintentionally coming off upward when the clip 10 is holding the condensing body 101. Also, when inserting the condensing body 101 into the clip 10, the condensing body 101 abuts against the upper opening surface 41 at the stepped portion 38. This allows the operator to easily visually confirm that the insertion of the condensing body 101 into the clip 10 is complete.

[0063] When the long device 100 held by the clip 10 is to be used again, the operator, with their eyes on the surface 11, grasps the upper frame 40 of the clip 10, one support frame 82 of the additional frame 80, and one lateral frame 60, as shown in Figure 11(A), and moves the clip 10 upward to remove it from the focusing body 101. The clip 10 has a set of notches, which consist of an outer notch 67 on one lateral frame 60 and an inner notch 66 on the other lateral frame 60. As a result, as shown in Figure 11(A), the operator can tilt the clip 10 in the lateral direction Z with respect to the extending direction of the focusing body 101, so that the inner notch 66 is closer to the focusing body 101, making it less likely for the focusing body 101 to get caught on the lower inner wall surface 64 of the groove 62, and making it easier to remove the clip 10 from the focusing body 101. Furthermore, when removing the clip 10 from the focusing body 101, the direction in which the lateral Z of the clip 10 is tilted relative to the extending direction of the focusing body 101 is the opposite direction to when attaching the clip 10 to the focusing body 101. In this embodiment, since the clip 10 has two sets of notches, both attachment to and removal from the focusing body 101 can be easily performed.

[0064] As described above, the clip 10 according to this embodiment can hold a bundle 101 formed by wrapping multiple flexible medical elongated devices 10 around each other, and is a flat plate-shaped clip 10 having a surface 11, a back surface 12 and a side surface 13, and has a frame 20 surrounding an opening 21 that penetrates in the thickness direction perpendicular to the surface 11, and a projection 30 that protrudes from the frame 20 into the inside of the opening 21, and the frame 20 has an upper frame 40 to which the projection 30 is connected, a lower frame 50 positioned on the opposite side of the upper frame 40 across the opening 21, and the upper frame 40 and the lower frame 50 The clip 10 has two lateral frames 60 positioned between the upper frame 40 and the lower frame 50, and each lateral frame 60 has a groove 62 extending from the opening 21 side to the side 13 side on the back surface 12, which includes an upper inner wall surface 63 on the side closer to the upper frame 40, a lower inner wall surface 64 on the side closer to the lower frame 50, and a bottom surface 65 positioned between the upper inner wall surface 63 and the lower inner wall surface 64. The tip 39 of the projection 30, which is the end on the projection side, is located below the lower inner wall surface 64 of the two grooves 62 formed in each lateral frame 60, in the direction from the upper frame 40 to the lower frame 50. As a result, the clip 10 can firmly hold the bundled body 101 by clamping it at three locations: the two grooves 62 formed in each lateral frame 60 and the surface 11 of the projection 30. Furthermore, because the clip 10 is thin and flat, it can be included in the individual packaging of the long device 100, making it less likely for the long device 100 to be contaminated due to damage to the storage bag 140 during storage or transport. Note that the fact that the bundled body 101 is held between the two grooves 62 and the three locations on the surface 11 of the projection 30 does not limit the bundled body 101 to contact the clip 10 at four or more locations. Therefore, for example, the bundled body 101 may contact two or more locations on the surface 11 of the projection 30, or two or more locations on each of the grooves 62.

[0065] Furthermore, the direction from the back surface 12 to the front surface 11 is defined as the height direction X2, and the direction from the front surface 11 to the back surface 12 is defined as the depth direction X1. The surface 11 of the highest part of the projection 30, which is the part that is highest in the height direction X2 from the back surface 12, is positioned in the thickness direction X to the depth direction X1 side of the surface 11 of the frame 20. This allows the clip 10 to guide the focusing body 101 between the back surface 12 of the frame 20 and the surface 11 of the projection 30. In addition, the surgeon can intuitively understand that the focusing body 101 is to be inserted between the surface 11 of the projection 30 and the back surface 12 of the frame 20. Moreover, when attaching the clip 10 to the focusing body 101, when the surgeon pushes the focusing body 101 upward, the focusing body 101 abuts against the upper opening surface 41. This allows the surgeon to easily visually confirm that the insertion of the focusing body 101 into the clip 10 is complete.

[0066] Furthermore, the surface 11 of the highest point 31 of the projection is positioned to coincide with the bottom surface 65 of the groove 62 in the thickness direction X. As a result, the clip 10 can grip the bundled body 101 at three locations: the two grooves 62 formed in each of the side frames 60 and the projection 30, thereby firmly holding the bundled body 101.

[0067] Furthermore, the upper inner wall surface 63 of the groove 62 of each lateral frame 60 is positioned on the same plane as the upper opening surface 41, which forms the upper side surface of the inner wall surface of the opening 21. As a result, when the clip 10 holds the condenser 101, the condenser 101 is in contact with the two upper inner wall surfaces 63 and the upper opening surface 41 of each groove 62, allowing the clip 10 to stably hold the condenser 101. In addition, when the operator attaches the clip 10 to the condenser 101, they can easily confirm that the condenser 101 is housed in the groove 62 even from the surface 11 side of the clip 10. As a result, the operator does not push the condenser 101 further into the groove 62 than necessary, and the clip 10 can suppress damage to the long device 100 and peeling of the coating.

[0068] Furthermore, the lower inner wall surface 64 of the groove 62 of at least one side frame 60 has a notch on the side surface 13 side. This allows the clip 10 to easily attach to and detach from the bundle 101 by moving the bundle 101 along the surface of the outer notch 67.

[0069] Furthermore, the notches form a set of notches consisting of an outer notch 67 formed on the side surface 13 of the lower inner wall surface 64 of one side frame 60 and an inner notch 66 formed on the opening 21 side of the lower inner wall surface 64 of the other side frame 60, and the clip 10 is provided with at least one set of notches. This makes it possible to prevent the bundle body 101 from getting caught on the lower inner wall surface 64 of the groove 62 by tilting the clip 10 relative to the bundle body 101 when attaching or detaching the clip 10 to the bundle body 101.

[0070] Furthermore, the area of ​​the outer notch 67 is greater than or equal to the area of ​​the inner notch 66. As a result, by making the area of ​​the outer notch 67 greater than or equal to the area of ​​the inner notch 66, the clip 10 can firmly hold the bundled body 101 while improving the ease of attachment and detachment to the bundled body 101.

[0071] Furthermore, the lower inner wall surface 64 of the groove 62 has a parallel portion 69 between the opening 21 side and the side surface 13 side, which is parallel to the upper inner wall surface 63 when viewed from the back surface 12 side in the thickness direction X. As a result, the clip 10 can prevent the bundled body 101 housed in the groove 62 from falling out in the depth direction X1, thereby ensuring that the bundled body 101 is securely housed in the groove 62.

[0072] Furthermore, the back surface 12 of the projection 30 is positioned on the depth side X1 from the front surface 11 toward the back surface 12 of the frame 20. As a result, even if the front surface 11 of the projection 30 is positioned on the depth side X1 of the frame 20, the clip 10 can maintain the thickness of the projection 30, thereby preventing damage to the projection 30.

[0073] Furthermore, the direction from the surface 11 to the back surface 12 is defined as the depth direction X1, and the surface 11 of the projection 30 has a central projection portion 34 which is flat, and an inclined portion 35 which slopes in the depth direction X1 as it extends from the central projection portion 34 toward the lateral frame 60. By having the inclined portion 35 of the projection 30, the clip 10 can increase the radius of curvature of the converging body 101 extending between the central projection portion 34 and the groove 62 compared to the case where the inclined portion 35 is not present. As a result, the clip 10 can reduce the load on the long device 100, thereby suppressing damage to the long device 100.

[0074] Furthermore, the projection 30 has a projection base 32 connected to the upper frame 40 and including a projection central portion 34 and an inclined portion 35, and a projection end portion 33 formed on the projection side of the projection 30 in the direction of projection than the projection base 32. The surface 11 of the projection end portion 33 and the surface 11 of the projection central portion 34 of the projection base 32 are smoothly connected, and a projection step portion 37 is formed between the surface 11 of the projection end portion 33 and the surfaces 11 of the two inclined portions 35 of the projection base 32. The smooth connection between the surface 11 of the projection end portion 33 and the surface 11 of the projection central portion 34 of the projection base 32 improves the operability of attaching and detaching the clip 10 to the bundler 101, while the projection step portion 37 formed between the surface 11 of the projection end portion 33 and the surfaces 11 of the inclined portion 35 firmly holds the bundler 101.

[0075] Furthermore, the frame 20 has an additional frame 80 positioned on the opposite side of the projection direction of the projection 30 relative to the upper frame 40, and an additional opening 22 that penetrates in the thickness direction between the additional frame 80 and the upper frame 40. As a result, the clip 10 can be packaged in individual packaging that houses the long device 100 by fitting the additional frame 80 onto the holder clip 130. In addition, since the clip 10 can grip the additional frame 80 when in use, the operability of attaching and detaching the clip 10 to the bundle 101 is improved.

[0076] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made by those skilled in the art within the technical framework of the present invention. For example, as shown in another modification in Figure 12, the lower inner wall surface 64 of the groove 62 may be formed with an inclination angle α with respect to the lateral direction Z such that the side surface 13 is lower than the opening 21.

[0077] Furthermore, as shown in yet another modification in Figure 13, the upper inner wall surface 63 and the lower inner wall surface 64 of the groove 62 may be formed with an inclination angle α with respect to the lateral direction Z such that the side surface 13 is lower than the opening 21. Preferably, the inclination angle α is greater than 0 degrees and less than 20 degrees. This allows the clip 10 to secure a sufficient minimum distance W in the vertical direction Y of the groove 62 relative to the converging body 101, thereby firmly holding the converging body 101 in the groove 62. If the inclination angle α is 20 degrees or more, the minimum distance W is likely to be smaller than the width of the converging body 101. As a result, it becomes difficult for the clip 10 to accommodate the converging body 101 in the groove 62, and the holding force of the clip 10 decreases. [Explanation of Symbols]
