Detailed Description

The medical device clip of the present utility model will be described with reference to the embodiments shown in the drawings.

The medical device clip 1 of the present utility model is a resin medical device clip 1, and includes a tubular holding portion 11 capable of holding a medical device 30 (here, a housing 30 accommodating a reshaper, which will be described later) and a mounting portion 12 capable of being mounted to another member 40 (here, a holding tube 40 of a guide wire, which will be described later) together with the medical device 30. The tubular holding portion 11 of the medical device clip 1 includes: a tubular body portion 13 for holding a medical device 30; a removal portion 14 extending over the entire axial length of the tubular body portion 13 for removing the medical device 30 from the tubular holding portion 11; and a take-out guide portion 15 provided between the tubular body portion 13 and the take-out portion 14 or provided in the take-out portion 14. The extraction guide 15 has a smaller wall thickness than the tubular body 11, is easier to deform than the tubular body 11, and expands when the medical device 30 is extracted.

In the present embodiment, as shown in fig. 1 to 5, the tubular holding portion 11 includes a tubular body portion 13 having a substantially cylindrical shape and extending in the axial direction (up-down direction in fig. 4). The tubular body 13 holds the medical device 30. As shown in fig. 5, the medical device 30 can be inserted in the axial direction into the tubular body portion 13 of the medical device clip 1 (see the blank arrow in fig. 5). The tubular body portion 13 (tubular holding portion 11) holds the medical instrument 30 by contacting (engaging) the inner surface thereof with the outer surface of the medical instrument 30 inserted in the axial direction.

The shape (inner surface shape) of the tubular body 13 is not limited to a cylindrical shape, and may be, for example, a polygonal tubular shape, a rounded polygonal tubular shape, or the like, corresponding to the shape (outer shape) of the medical device 30 to be held. The inner shape of the tubular body portion does not need to be the same as that of the medical device to be held, and for example, a medical device having a polygonal tubular shape can be held in the tubular body portion having a tubular shape.

The tubular holding portion 11 includes a take-out portion 14 extending over the entire axial length of the tubular body portion 13. In this embodiment, as shown in fig. 2 and 4, the tubular main body portion 13 is cut out over the entire axial length, and thus the tubular holding portion 11 is formed with a take-out portion 14 (medical instrument take-out slit) for taking out the medical instrument 30 from the tubular holding portion 11. When the medical device 30 is taken out from the medical device clip 1, the medical device 30 held by the tubular holding portion 11 is lifted up to the taking-out portion 14 (upward in fig. 2), the tubular holding portion 11 is elastically deformed, and the medical instrument 30 can be taken out from the expanded take-out portion 14 (including a take-out guide portion 15 described later).

In the present embodiment, the take-out portion 14 includes the take-out opening 16, the take-out guide portion 15 includes two axially extending and opposing axial surface portions 17, and the distance between the opposing axial surface portions 17, 17 becomes shorter as the take-out opening 16 is approached. Specifically, as shown in fig. 2, the extracting portion 14 (medical device extracting slit) includes an extracting opening 16 that opens over the entire axial length of the tubular body portion 13 at an upper end portion (upper end portion in fig. 2) of the extracting portion 14. The extraction guide portion 15 is provided between the tubular body portion 13 and the extraction portion 14, and includes two axial surface portions 17 and 17. The two axial surface portions 17, 17 are planar portions (axial planar portions) extending in the axial direction of the tubular body portion 13 (the direction perpendicular to the paper surface in fig. 2).

The two axial surface portions 17, 17 are symmetrical with respect to the extraction portion 14 (extraction opening 16). The two axial surface portions 17, 17 are inclined so that the distance therebetween becomes shorter gradually as going toward the take-out opening 16 (upward in fig. 2). In this embodiment, as shown in fig. 2, the distance (opening width) of the outer surface side of the extraction guide portion 15 of the extraction portion 14: do ratio is the distance (opening width) on the inner surface side between the opposite two axial face portions 17, 17: di is short.

In the present embodiment, in the extracting portion 14 (extracting guide portion 15), the distance between the opposing axial surface portions 17, 17 becomes shorter as the extracting opening 16 is approached, so that the medical instrument 30 can be prevented from accidentally coming off the tubular body portion 13. On the other hand, in other words, in the extracting portion 14 (extracting guide portion 15), the distance between the two opposing axial surface portions 17, 17 becomes longer toward the inside of the tubular body portion 13, so that the medical instrument 30 is guided outward (extracting opening 16) when the medical instrument 30 is extracted, and the medical instrument 30 is easily extracted during operation.

In the present embodiment, the tubular body portion 13 is cut out over the entire axial length, and the removal portion 14 (medical device removal slit) for removing the medical device 30 from the tubular holding portion 11 is formed in the tubular holding portion 11, so that the tubular body portion 13 can be elastically deformed to some extent in the direction in which its inner shape (inner diameter) is widened. Thus, even when the outer shape (outer diameter) of the medical device is larger than the inner shape (inner diameter) of the tubular body portion before holding the medical device to a certain extent, the tubular body portion can hold the medical device. Further, since the tubular body portion can hold medical devices having different outer shapes (outer diameters) within a certain range, one medical device clip can be used for a plurality of medical devices.

The extraction portion 14 includes an extraction opening 16, and the extraction guide portion 15 has a wall thickness that becomes thinner as the extraction opening 16 is approached in a cross section on a surface orthogonal to the axial direction of the tubular body portion 13. Specifically, as shown in fig. 2 (fig. 2 is a front view of the medical device clip 1, but in the present embodiment, since the medical device clip 1 has the same cross section in the axial direction, the description will be based on fig. 2), the wall thickness in the horizontal direction of the extraction guide portion 15 becomes thinner as it goes toward the extraction opening 16 in a cross section in a plane orthogonal to the axial direction of the tubular body portion 13.

That is, as shown in fig. 2, the wall thickness t3 of the portion in the vicinity of the take-out opening 16 of the take-out guide 15 is smaller than the wall thickness t2 of the portion of the take-out guide 15 on the side of the tubular body portion 13 than the measurement portion of the wall thickness t3 (t 2 > t 3). The wall thicknesses t2 and t3 are smaller than the wall thickness t1 of the tubular body portion 13 (the portion near the extraction guide portion 15 of the tubular body portion 13) (t 1 > t2 > t 3), and thus the extraction guide portion 15 is easier to deform than the tubular body portion 13 and is easier to spread out when the medical device 30 is extracted.

In the present embodiment, the wall thickness (wall thickness in the horizontal direction) of the extraction portion 14 (extraction guide portion 15) becomes thinner as it goes toward the extraction opening 16, so that the extraction guide portion 15 is more easily deformed at the extraction opening 16 side portion, and the medical device 30 is easily extracted during operation. On the other hand, in other words, the wall thickness (wall thickness in the horizontal direction) of the extraction portion 14 (extraction guide portion 15) becomes thicker toward the tubular body portion 13, so that the portion on the side of the tubular body portion 13 holding the medical device 30 is less likely to be accidentally deformed, and the medical device 30 can be prevented from being accidentally detached from the tubular body portion 13.

In the present embodiment, as shown in fig. 3, the inclination of the axial surface portion 17 (angle θ1 shown in fig. 3) is preferably the same as or greater than the inclination of the tangent (X) to the outer peripheral surface of the tubular body portion 13 at the lower end of the axial surface portion 17 (angle θ2 shown in fig. 3). As a result, the wall thickness (wall thickness in the horizontal direction) of the entire extraction portion 14 (extraction guide portion 15) can be made thinner than the wall thickness (t 1) of the tubular body portion 13 (portion in the vicinity of the extraction guide portion 15 of the tubular body portion 13) and made thinner as the extraction opening 16 is approached.

In this embodiment, as shown in fig. 2 and 4, the upper portion of the tubular body 13 is cut away, and two upper flat portions 18, 18 are formed at the upper end of the tubular body 13 through the take-out opening 16. By forming such upper flat portions 18, 18 (cutting the upper side portion of the tubular body portion 13), the angle of the edge portion (the corner portion formed by the outer surface of the tubular holding portion 11 and the axial surface portion 17) formed as the edge of the extraction opening 16 can be made gentle in the tubular holding portion 11. This reduces the occurrence of burrs at the edge portion, and the finger hook during the medical device removal operation can be reduced.

As shown in fig. 2, a coupling portion 19 extends from a side portion (a right side portion in fig. 2) of the tubular holding portion 11 (the tubular main body portion 13) toward the mounting portion 12 described later. The coupling portion 19 is a plate-like member that couples the tubular holding portion 11 and the mounting portion 12 and extends over the entire axial length of the tubular body portion 13, and has one end connected to the tubular holding portion 11 and the other end connected to the mounting portion 12.

The medical device clip 1 includes an attachment portion 12 that can be attached to another (separate) member 40 together with the medical device 30. In the present embodiment, as shown in fig. 1 to 4, the medical device clip 1 includes two attachment portions 12, 12 connected to each other. Each of the mounting portions 12 has a substantially cylindrical shape and extends in the axial direction (up-down direction in fig. 4). Each of the mounting portions 12 is formed with an opening (slit) 20 extending over the entire axial length of the mounting portion 12. The width of the opening 20 is preferably the same as or slightly smaller than the profile (outer diameter) of the other component 40 to be mounted. Each mounting part 12 via the opening 20 are mounted to other components 40. The attachment portion 12 is preferably elastically deformable so that the opening 20 can be opened when attached to the other member 40. When the mounting portion 12 is mounted to the other member 40 through the opening 20, the other member 40 may be elastically deformed.

In the present embodiment, as shown in fig. 2, the bottom (the lowermost and axially extending linear portion) of the tubular holding portion 11 (the tubular main body portion 13) and the bottom (the lowermost and axially extending linear portion) of each mounting portion 12 are located on the same plane (P). This has advantages such as being stable in the packaged state of the medical device clip 1, being capable of placing the medical device clip 1 (and the medical device set 10 described later) in a flat surface (for example, the upper surface of a table) in a stable state, and being capable of stably performing a cutting process when the medical device clip 1 is manufactured by extrusion molding.

As a material for forming the medical device clip 1, a hard or semi-hard resin that can be elastically deformed to some extent is preferable. Examples thereof include polyvinylidene fluoride, polycarbonate, acrylic resin (for example, polyacrylate, specifically, PMMA: polymethyl methacrylate), polyacrylamide, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, etc.), polyester (for example, polyethylene terephthalate, polybutylene terephthalate), polyolefin (for example, polyethylene, polypropylene, ethylene-propylene copolymer), styrene resin (for example, polystyrene, MS resin (methyl acrylate-styrene copolymer), MBS resin (methyl acrylate-butene-styrene copolymer), polyvinyl chloride (hard vinyl chloride), polyamide (6 nylon, 66 nylon), etc. As the material for forming the clip 1 for medical devices, rubber materials having elasticity (for example, butyl rubber, latex rubber, silicone rubber, styrene-butadiene rubber, isoprene rubber, etc.), thermoplastic elastomers (for example, styrene-based elastomers such as SBS elastomer, SEBS elastomer, SEPS elastomer, etc., olefin-based elastomers such as ethylene- α -olefin copolymer elastomer, etc.), etc. may be used.

The clip 1 for medical devices can be manufactured by a known method such as extrusion molding or injection molding, and can be preferably manufactured by extrusion molding. When the medical device clip 1 is manufactured by extrusion molding, the medical device clip 1 preferably has substantially the same cross-sectional shape over the entire axial length.

As the other member 40 to which the medical device clip 1 (the attaching portion 12) is attached, other members to be used together with the medical device, other members to be provided at a place where the medical device is used (for example, a medical bed, a stent), and the like can be cited, and the other member 40 is preferably a catheter or a guide wire holding tube.

As the medical device 30 held by the medical device clip 1 (the tubular holding portion 11), various known medical devices can be cited, and the medical device 30 is preferably a reshaper, a guidewire torque device, a catheter hub, an injection needle, a catheter clip, a guidewire clip or a connector, or a housing accommodating the above-mentioned components.

As the medical device clip 1a shown in fig. 6 to 9, at least one (both of the axial surface portions 17 and 17 in this case) of the two axial surface portions 17 and 17 may be provided with a removal start assisting portion that makes a distance between the two axial surface portions 17 and 17 at the axial end portion of the tubular body portion 13 longer so as to facilitate removal of the medical device 30.

Specifically, in the clip 1a for medical devices shown in fig. 6 to 9, one (lower side in fig. 8) end portion in the axial direction of the two axial direction face portions 17, 17 is cut into a curved shape in a plan view, thereby forming the extraction start auxiliary portions 21a, 22a. In other words the first and second phase of the process, the removal start assisting portions 21a, 22a are curved surface portions formed at axial end portions of the axial surface portion 17. In the formed portions of the extraction start auxiliary portions 21a, 22a, the distance between the two axial surface portions 17, 17 is longer than in the portions where the extraction start auxiliary portions 21a, 22a are not formed.

As shown in the clip 1b for medical devices shown in fig. 10 to 12, the removal start auxiliary portion may be a removal start auxiliary portion 21b, 22b formed by cutting one (lower side in fig. 12) end portion in the axial direction of the two axial surface portions 17, 17 into a straight line in a plan view. In the medical device clip 1b, the distance between the two axial surface portions 17 and 17 is made longer in the forming portions of the extraction start auxiliary portions 21b and 22b than in the portions where the extraction start auxiliary portions 21b and 22b are not formed.

In the above-described medical instrument clips 1a and 1b, when the medical instrument 30 is taken out from the taking-out portion 14 of the tubular holding portion 11, the medical instrument 30 is guided along the taking-out start auxiliary portions 21a, 22a, 21b, and 22b toward the taking-out opening 16, and when the medical instrument 30 is taken out, stress is concentrated at the contact portions of the taking-out start auxiliary portions 21a, 22a, 21b, and 22b and the medical instrument 30, and deformation (expansion) of the taking-out guide portion 15 is promoted, so that the medical instrument 30 is easily taken out.

In the medical device clips 1a and 1b, the pair of extraction start auxiliary portions 21a and 22a and 21b and 22b are asymmetric. Specifically, the 1 st extraction start auxiliary portions 21a and 21b are cut larger in the axial direction of the tubular holding portion 11 and in the direction orthogonal to the axial direction than the 2 nd extraction start auxiliary portions 22a and 22b. The 2 nd extraction start auxiliary portions 22a, 22b are formed by cutouts that are small in both the axial direction of the tubular holding portion 11 and in the direction orthogonal to the axial direction. Accordingly, when the medical device 30 is removed, the timings at which the stress is concentrated in each of the pair of removal start auxiliary portions 21a, 22a and 21b, 22b (timings at which each of the removal start auxiliary portions contacts the medical device 30) can be shifted in the axial direction, and therefore the medical device 30 can be easily removed.

The pair of extraction start support portions 21a, 22a and 21b, 22b may be symmetrical. In the medical device clips 1a and 1b, the extraction start auxiliary portions 21a, 22a, 21b, and 22b may be provided at one end portion in the axial direction of the tubular body portion 13, or at both end portions. In the case where the removal start assisting portion is provided only at one end portion in the axial direction of the tubular body portion, the medical device is preferably inserted in the axial direction from the side of the tubular body portion where the removal start assisting portion is provided (see the blank arrow in fig. 9). As shown in fig. 9, the amount of protrusion of the medical device 30 from the tubular body portion 13 on the side where the removal start auxiliary portions 21a, 22a are provided is preferably smaller than the amount of protrusion from the opposite side.

In the medical device clip 1, the axial surface portion 17 of the removal portion 14 (the removal guide portion 15) is a planar portion extending in the axial direction, but the present utility model is not limited thereto. For example, as shown in the clip 1c for medical devices shown in fig. 13, the axial surface portion 17 may be a curved surface extending in the axial direction. In fig. 13, the axial surface portion 17 is a concave portion recessed in the lateral direction and extending in the axial direction.

As shown in the clip 1d for medical devices shown in fig. 14, the peripheral edge portion (inner edge portion, portion corresponding to the edge portion) of the removal opening 16 may be chamfered. By providing the chamfer portion, the resistance to the taking-out operation of the medical appliance becomes smaller, the removal operation becomes easier. In this case, the distance (opening width) between the two opposing axial surface portions 17, 17 on the outer surface side: do is defined as a portion of the extraction guide 15 where the distance between the two axial surface portions 17, 17 is shortest.

Next to this, the process is carried out, another embodiment of the medical device clip according to the present utility model will be described with reference to the examples shown in the drawings. In the following description, the same components as those of the medical device clip 1 are denoted by the corresponding names and reference numerals, and detailed description thereof is omitted.

As shown in fig. 15 to 17, in the clip 2 for medical devices, the extraction portion 23 includes two upper end portions 24, 24 that extend in the axial direction and face each other. The medical device clip 2 includes thin plate portions 25, 25 extending from one or both (here, both) of the opposite upper end portions 24, 24 to the opposite other upper end portion 24, and having a thickness thinner than that of the tubular body portion 13, and the extraction guide portion is formed by upper concave portions 27, 27 provided adjacent to the thin plate portions 25, 25.

Specifically, as shown in fig. 15 to 17, in the removal portion 23 of the medical device clip 2, the tubular body portion 13 is cut out (a slit for removing a medical device is formed) over the entire axial length. The medical device clip 2 further includes thin plate portions 25, 25 extending toward the opposite upper end 24 and having a thickness thinner than that of the tubular body portion 13 at both upper ends 24, 24 of the removal portion 23 (medical device removal slit in the removal portion 23). In the present embodiment, the thin plate portions 25, 25 narrow the openings of the cutout portions formed in the cylindrical body portion 13, and narrow openings are formed between the opposing thin plate portions 25, 25. In the present embodiment, as shown in fig. 16, the thin plate portion 25 has a wall thickness t4 that is thinner than a wall thickness t6 in the horizontal direction of the tubular body portion 13 (a portion near the extraction guide portion (the forming portion of the upper concave portion 27) of the tubular body portion 13).

The medical device clip 2 further includes two upper concave portions 27, 27 extending in the axial direction and facing each other below the thin plate portions 25, 25 and above the tubular body portion 13. In the medical device clip 2, the upper concave portions 27, 27 form extraction guide portions. In other words, in the clip 2 for medical devices, the cutout portion (slit for medical device removal) is formed so as to be wider toward the outside of the tubular body portion 13 (upward in fig. 16), and an upper concave portion 27 serving as a removal guide is formed between a portion (upper portion) of the cutout portion and a base end portion (portion on the upper end 24 side) of the thin plate portion 25.

In the present embodiment, the extraction guide portion (the portion where the upper concave portion 27 is formed) has a thinner wall thickness than the tubular body portion 13. Specifically, as shown in fig. 16, the wall thickness t5 in the horizontal direction of the extraction guide portion (the portion where the upper concave portion 27 is formed) is thinner than the wall thickness t6 in the horizontal direction of the tubular body portion 13 (the portion in the vicinity of the extraction guide portion of the tubular body portion 13). This makes the removal guide portion (the portion where the upper concave portion 27 is formed) more easily deformed than the tubular body portion 13, and is easily spread out when the medical device 30 is removed. The extraction guide portion (the portion where the upper concave portion 27 is formed) has a wall thickness (wall thickness in the horizontal direction) t5 that is thicker than the wall thickness t4 of the thin plate portion 25.

In the medical device clip 2, the thin plate portion 25 is thinner than the tubular body portion 13 and the upper concave portions 27, and is easier to deform than the tubular body portion 13 and the upper concave portions 27, and is easier to spread out when the medical device 30 is taken out. This facilitates the removal of the medical device 30 during the operation. In other words, in the medical device clip 2, a part of the removal portion 23 (medical device removal slit) is covered with the pair of thin plate portions 25, 25. This also functions as an unexpected detachment prevention portion (an unexpected force-receiving portion when the medical instrument is subjected to unexpected force during transport, etc.) of the medical instrument 30 from the tubular body portion 13.

As shown in the clip 2a for medical devices shown in fig. 18, only one of the thin plate portions 25 may extend from only one of the two opposite upper end portions 24, 24 (here, the upper end portion 24 on the left side in fig. 18) to the other opposite upper end portion 24, and may be formed to be thinner than the tubular body portion 13 and the upper concave portion 27.

As shown in fig. 19, the clip for medical devices is a pair of thin plate portions 25, 25 extending from the other upper end 24 opposite to the two upper end 24, 24 in the opposite direction, and at least one (both) of the pair of thin plate portions 25, 25 extends toward the other upper end 24 of the axial end portion of the tubular body portion 13 by a small amount. Thus, the medical device 30 is easily inserted between the thin plate portions 25, 25 when the medical device 30 is taken out.

Specifically, in the clip 2b for medical devices shown in fig. 19, one (lower side in fig. 19) end portion in the axial direction of the pair of thin plate portions 25, 25 is cut into a curved shape in a plan view, thereby forming easy-entry portions 28b, 29b for medical devices. In other words, the easy-entry portions 28b, 29b of the medical instrument are curved surface portions formed at axial end portions of the thin plate portion 25. The portions of the thin plate portion 25 where the easy-entry portions 28b, 29b of the medical instrument are formed are smaller than the portions of the medical instrument where the easy-entry portions 28b, 29b are not formed in terms of the amount of extension of the thin plate portion 25 in the direction of the other upper end portion 24.

As shown in the clip 2c for medical devices shown in fig. 20, the easy-entry portion of the medical device may be formed by cutting one (lower side in fig. 20) end portion in the axial direction of the pair of thin plate portions 25, 25 into a straight line in a plan view. In the medical device clip 2c, the extension amount of the formed portions of the easy-entry portions 28c, 29c of the medical device in the direction of the other upper end 24 of the thin plate portion 25 is made smaller than the portions of the medical device where the easy-entry portions 28c, 29c are not formed.

In the above-described medical instrument clips 2b and 2c, when the medical instrument 30 is finally taken out from the taking-out portion 23 of the tubular holding portion 11, the medical instrument 30 is guided outward of the tubular holding portion 11 along the easy-to-enter portions 28b, 29b, 28c, 29c of the medical instrument, and when the medical instrument 30 is taken out, stress is concentrated at the contact portions of the easy-to-enter portions 28b, 29b, 28c, 29c of the medical instrument and the medical instrument 30, and therefore, the deformation (expansion) of the easy-to-enter portions 28b, 29b, 28c, 29c of the medical instrument is easy to take out the medical instrument 30.

In the medical device clips 2b and 2c, the pair of medical device accessible portions 28b and 29b and 28c and 29c are asymmetric. Specifically, the 1 st extraction start auxiliary portions 28b and 28c are cut larger in the axial direction of the tubular holding portion 11 and in the direction orthogonal to the axial direction than the 2 nd extraction start auxiliary portions 29b and 29 c. Accordingly, when the medical instrument 30 is taken out, the timings at which the stress is concentrated in the auxiliary parts for starting the taking-out (the timings at which the easy-entry parts of the medical instruments are in contact with the medical instrument 30) in the pair of easy-entry parts 28b, 29b and 28c, 29c can be shifted in the axial direction, and therefore the medical instrument 30 can be easily taken out. The manner of the pair of easy-access portions 28b, 29b and 28c, 29c of the medical device may be symmetrical.

In the medical device clips 2b and 2c, the easy-entry portions 28b, 29b, 28c, and 29c of the medical devices are provided at one end portion in the axial direction of the tubular body portion 13, but may be provided at both end portions. When the easy-entry portions 28b, 29b, 28c, and 29c of the medical instrument are provided only at one axial end portion of the tubular body portion 13, the medical instrument 30 is preferably inserted in the axial direction from the side (lower side in fig. 19 and 20) of the tubular body portion 13 where the easy-entry portions 28b, 29b, 28c, and 29c of the medical instrument are provided. It is preferable that the amount of protrusion of the medical device 30 from the tubular body portion 13 on the side where the easy-entry portions 28b, 29b, 28c, 29c of the medical device are provided is shorter than the amount of protrusion from the opposite side.

As shown in the clip 2d for medical devices shown in fig. 21 to 23, the thin plate portion may be a pair of thin plate portions 25, 25 extending from the other upper end 24 opposed in the two directions of the opposed upper end portions 24, and at least a part of the distal end side portions of the pair of thin plate portions 25, 25 may overlap. The front end side portions of the pair of thin plate portions 25, 25 overlap, thus, the medical device 30 can be more reliably prevented from accidentally coming off the tubular body portion 13.

Even when the distal end side portions of the pair of thin plate portions 25, 25 overlap, as shown in the medical instrument clips 2e and 2f shown in fig. 24 and 25, the thin plate portions can be provided with the easy-entry portions 28e, 29e and 28f, 29f for the medical instrument that make the axial end portion of the tubular body portion 13 extend to the other upper end portion 24 less, and that make it easy to take out the medical instrument 30. This can obtain substantially the same operational effects as the easy-entry portions 28b, 29b and 28c, 29c of the medical device.

Next, a medical device set including the clip for medical devices of the present utility model will be described with reference to the embodiments shown in the drawings.

As shown in fig. 26, the medical device set 10 of the present utility model includes the medical device clip (here, the medical device clip 1), the medical device 30, and other members 40.

The other member 40 is preferably a catheter or a guide wire holding tube. The medical device 30 is preferably a reformer, a guidewire torque device, a catheter hub, an injection needle, a catheter clip, a guidewire clip or a connector, or a housing accommodating the above components. The medical device 30 is held by the medical device clip 1 attached to the other member 40. In this embodiment, as shown in fig. 26, the medical device 30 is a housing 30 in which a reshaper is housed, and the other member 40 is a guide wire holding tube 40. A guidewire is housed in the holding tube 40. As described above, the medical device 30 is inserted and held in the axial direction in the tubular body portion 13 of the medical device clip 1.

In this embodiment, as shown in fig. 26, the two attachment portions 12 and 12 connected to each other are attached to a holding tube 40 of a guide wire wound in a circular shape. Thus, the mounting portion 12 also functions as a member for maintaining the shape (state of being wound in a circular shape) of the guide wire holding tube 40.

The medical device set 10 includes a medical device clip 1, a medical device 30, and other components 40. As a result, as described above, the medical device 30 can be prevented from being accidentally detached, and the medical device 30 can be easily removed during the operation.

As shown in the clip 1e for medical devices shown in fig. 27, the removal portion 14 (slit for removing medical devices) may be provided on the side of the tubular holding portion 11 (tubular body portion 13). In other words, the direction in which the removal portion 14 (medical device removal slit) is provided in the tubular holding portion 11 (tubular body portion 13) (the direction in which the medical device 30 is removed) may be different from the opening direction of the opening 20 of the mounting portion 12.

Further, there is no need to provide a plurality of attachment portions, and as shown in fig. 28, the medical device clip 1f may be provided with one attachment portion 12f. The mounting portion 12f of the present embodiment is larger than the mounting portion 12 described above, and can be mounted on a larger other member (for example, a medical bed, a stand, or the like).

The extraction guide portion (thin plate portion 25 g) may be provided at a part of the tubular body portion 13 in the axial direction as shown in the clip 2g for medical devices shown in fig. 29, without being provided over the entire axial length of the tubular body portion.

As shown in the clip 1g for medical devices shown in fig. 30, an outer peripheral portion (outer surface portion) of the tubular body portion 13 corresponding to the axial surface portion (axially inner surface portion) 17 may be a planar portion (axially outer peripheral surface portion 31) extending in the axial direction. Here, the inclination of the axial surface portion 17 (angle θ3 shown in fig. 30) is preferably the same as or greater than the inclination of the axial outer peripheral surface portion 31 (angle θ4 shown in fig. 30). As a result, the wall thickness (wall thickness in the horizontal direction) of the entire extraction portion 14 (extraction guide portion 15) can be made thinner than the wall thickness of the tubular body portion 13 (portion in the vicinity of the extraction guide portion 15 of the tubular body portion 13), and can be made thinner as the extraction opening 16 is made thinner.

In the clip for medical devices, the connection portion (connection portion 19) for connecting the tubular holding portion and the attachment portion may not be provided, and the tubular holding portion and the attachment portion may be directly connected.
