[Figure 11] This figure shows a modified example of the first covering portion shown in Figure 10. [Figure 12] This is a cross-sectional view along line II in Figure 10. [Figure 13] Figure 2 shows one modified example of the treatment aid shown. [Modes for carrying out the invention]

[0019] Hereinafter, embodiments of the therapeutic aids relating to this disclosure will be illustrated with reference to the drawings. In each figure, identical components are denoted by the same reference numerals.

[0020] Figure 1 shows an example of a procedure using a guidewire as a long medical instrument X. In the example shown in Figure 1, the guidewire is rotated with the right hand (see curved arrow) and moved back and forth with the left hand (see straight arrow). Procedures like the one shown in Figure 1 are performed, for example, in cardiac catheterization surgery. When performing cardiac catheterization surgery, multiple types of catheters and guidewires are used. However, the procedure of approaching the coronary arteries using a guiding catheter and guidewire is considered difficult for the following reasons. (1) Guiding catheters and guidewires are thin and have a circular cross-section, making them physically difficult to grasp, and manual manipulation does not easily synchronize with the movement of the tip (rotational torque is not easily transmitted). (2) Although guiding catheters are designed with features such as not coating the gripping portion to improve grip strength, the surface resistance is reduced and they become more slippery than before use (when dry) due to priming with saline solution and the adhesion of blood during the procedure.

[0021] Against this backdrop, the therapeutic aid described herein is used to facilitate the rotation of long medical instruments X, such as guiding catheters and guidewires. More specifically, the therapeutic aid described herein is used, for example, in cardiac catheterization procedures when locally administering regenerative medicine products into the coronary arteries. However, the uses of the therapeutic aid described herein are not limited to this.

[0022] Figure 2 shows a therapeutic aid 1 as one embodiment of the therapeutic aid according to the present disclosure. As shown in Figure 2, the therapeutic aid 1 comprises a first covering portion 10 and a second covering portion 20. The first covering portion 10 and the second covering portion 20 are each configured to cover the fingers.

[0023] Figure 3 shows the treatment aid 1 being worn on the hand H. As shown in Figures 2 and 3, the treatment aid 1 of this embodiment is a glove in which the first covering portion 10 and the second covering portion 20 are integrally formed. The glove as the treatment aid 1 of this embodiment is configured to be worn on the right hand H. The glove as the treatment aid 1 is flexible. Therefore, the user can freely move the hand H on which the treatment aid 1 is worn.

[0024] As shown in Figures 2 and 3, the first covering portion 10 is provided with a support groove 15 into which a long medical instrument X can be fitted. The second covering portion 20 is provided with a rail surface 25 that can clamp the long medical instrument X, which is fitted into the support groove 15, between itself and the inner surface 15a of the support groove 15.

[0025] Figures 4 and 5 illustrate the operation of rotating a long medical instrument X with a hand H wearing the treatment aid 1. Figures 6 and 7 are enlarged views illustrating the principle of rotating the long medical instrument X. When rotating the long medical instrument X using the treatment aid 1, first, as shown in Figures 4 and 6, the long medical instrument X is fitted into the support groove 15 and then clamped between the inner surface 15a of the support groove 15 and the rail surface 25. In this state, as shown in Figures 5 and 7, by moving the first covering portion 10 and the second covering portion 20 relative to each other, rotational torque is transmitted to the long medical instrument X by the frictional force between the long medical instrument X and the rail surface 25, causing the long medical instrument X to slide against the inner surface 15a of the support groove 15 and rotate. In this way, the long medical instrument X can be easily rotated by using the treatment aid 1.

[0026] Next, we will describe further details of treatment aid 1.

[0027] In this embodiment, the coefficient of friction of the inner surface 15a of the support groove 15 is smaller than the coefficient of friction of the rail surface 25. This makes it easier to transmit rotational torque to the long medical instrument X via the rail surface 25, and also makes it easier to slide the long medical instrument X on the inner surface 15a of the support groove 15. As a result, it becomes easier to rotate the long medical instrument X.

[0028] The first covering portion 10 includes a support portion 11 with a support groove 15. The second covering portion 20 includes a rail portion 21 with a rail surface 25. Here, the "thickness direction of the support portion 11" and the "thickness direction of the rail portion 21" are defined as the opposing directions of the inner surface 15a of the support groove 15 and the rail surface 25 when the long medical instrument X is held between the inner surface 15a of the support groove 15 and the rail surface 25. In this case, the rigidity of the support portion 11 in the thickness direction of this embodiment is greater than the rigidity of the rail portion 21 in the thickness direction. By doing so, deformation of the support groove 15 can be suppressed when the long medical instrument X is rotated, and the long medical instrument X is less likely to fall out of the support groove 15.

[0029] The first covering portion 10 of this embodiment comprises a cylindrical first covering body portion 18 capable of covering fingers, and a support portion 11 provided on the surface of the first covering body portion 18. The first covering portion 10 of this embodiment forms a thicker portion at the location of the support portion 11 than other portions. In other words, in the first covering portion 10 of this embodiment, the maximum thickness of the portion where the support portion 11 is located is greater than the maximum thickness of other portions. The second covering portion 20 of this embodiment comprises a cylindrical second covering body portion 28 capable of covering fingers, and a rail portion 21 provided on the surface of the second covering body portion 28. The second covering portion 20 of this embodiment forms a thicker portion at the location of the rail portion 21 than other portions. In other words, in the second covering portion 20 of this embodiment, the maximum thickness of the portion where the rail portion 21 is located is greater than the maximum thickness of other portions.

[0030] The thickness of the support portion 11 in this embodiment is 3 mm or more and 5 mm or less. Also, the thickness of the rail portion 21 in this embodiment is 3 mm or more and 5 mm or less.

[0031] Figure 10 shows the details of the first covering portion 10. As shown in Figure 10, at least one support groove 15 of this embodiment is provided in each of the following regions: the region corresponding to the area from the tip of the finger to the first joint (hereinafter simply referred to as "first region A1"), and the region corresponding to the area from the first joint to the second joint of the finger (hereinafter simply referred to as "second region A2"). In other words, the first covering portion 10 is provided with a plurality of support grooves 15, and the plurality of support grooves 15 include support grooves 15 provided in the first region A1 (hereinafter simply referred to as "first support groove 15") and support grooves 15 provided in the second region A2 (hereinafter simply referred to as "second support groove 15").

[0032] Figures 4 and 5 show the rotation of a long medical instrument X while it is fitted into the first support groove 15, and Figures 8 and 9 show the rotation of a long medical instrument X while it is fitted into the second support groove 15. As shown in Figures 4 and 5, when the long medical instrument X is rotated while it is fitted into the first support groove 15, the long medical instrument X can be operated at a position close to the fingertips, enabling delicate operation of the long medical instrument X. On the other hand, as shown in Figures 8 and 9, when the long medical instrument X is rotated while it is fitted into the second support groove 15, it is easier to transmit a large rotational torque to the long medical instrument X. In other words, by having at least one support groove 15 in each of the first region A1 and the second region A2, it is possible to use both delicate operation of the long medical instrument X and operation that transmits a large rotational torque to the long medical instrument X.

[0033] As shown in Figure 10 and other figures, the first covering portion 10 of this embodiment comprises a plurality (three in this embodiment) of first support grooves 15 and a plurality (two in this embodiment) of second support grooves 15. The plurality of first support grooves 15 are arranged at intervals along the length L of the fingers. The plurality of second support grooves 15 are also arranged at intervals along the length L of the fingers.

[0034] The first support groove 15 is provided in the support portion 11 located in the first region A1 (hereinafter simply referred to as "first support portion 11"). The second support groove 15 is provided in the support portion 11 located in the second region A2 (hereinafter simply referred to as "second support portion 11"). The support groove 15 is a groove formed so as to be recessed in the thickness direction from the upper end (surface) of the support portion 11.

[0035] As shown in Figure 10 and other figures, the support groove 15 in this embodiment extends along a direction intersecting the longitudinal direction L of the fingers. This makes it easier to fit the long medical instrument X into the support groove 15 compared to the case where the support groove 15 extends along the longitudinal direction L of the fingers.

[0036] More specifically, as shown in Figure 10, the support groove 15 of this embodiment extends along a direction perpendicular to the longitudinal direction L of the fingers. However, the direction of extension of the support groove 15 is not limited to the direction shown in Figure 10, and may extend along a direction inclined with respect to the direction perpendicular to the longitudinal direction L of the fingers, as shown in the modified example in Figure 11. Also, although all of the multiple support grooves 15 shown in Figure 10 extend along the same direction, some of the support grooves 15 may extend along a different direction from the other support grooves 15. For example, some of the support grooves 15 may extend along a direction perpendicular to the longitudinal direction L of the fingers, while the other support grooves 15 may extend along a direction inclined with respect to the direction perpendicular to the longitudinal direction L of the fingers.

[0037] Figure 12 is a cross-sectional view taken along line II in Figure 10. Specifically, Figure 12 is a cross-sectional view taken along a cross-sectional line perpendicular to the extending direction of the support groove 15. As shown in Figure 12, it is preferable that the opening width W of the support groove 15 is larger than the outer diameter of the long medical instrument X. In this specification, "opening width W of the support groove 15" means the opening width at the center of the extending direction of the support groove 15. This makes it easier to fit the long medical instrument X into the support groove 15 and to slide the long medical instrument X on the inner surface 15a of the support groove 15. On the other hand, if the opening width W of the support groove 15 is too large, the long medical instrument X is more likely to fall out of the support groove 15. Here, the outer diameter of the guiding catheter is generally in the range of 1.5 mm to 2.0 mm, and the outer diameter of the guide wire is generally 0.35 mm. Therefore, the opening width W of the support groove 15 is preferably 2.0 mm or more and 3.0 mm or less when the long medical instrument X is a guiding catheter, and preferably 0.4 mm or more and 0.45 mm or less when the long medical instrument X is a guide wire.

[0038] As shown in Figure 12, the inner surface 15a of the support groove 15 in this embodiment has a semicircular bottom surface 16 and a pair of side surfaces 17 that rise from both ends of the bottom surface 16 along the thickness direction of the support portion 11, in a cross-sectional view perpendicular to the extending direction of the support groove 15. The inner surface 15a of the support groove 15 in this embodiment, formed by the bottom surface 16 and the pair of side surfaces 17, has a U-shape in a cross-sectional view perpendicular to the extending direction of the support groove 15. The opening width W of the support groove 15 in this embodiment is the same as the diameter of the bottom surface 16.

[0039] The depth D of the support groove 15 is configured to be smaller than the outer diameter of the long medical instrument X. In this specification, "depth D of the support groove 15" means the depth at the center of the extension direction of the support groove 15. In this way, the long medical instrument X can protrude from the support groove 15 while it is fitted into the support groove 15. Therefore, when the long medical instrument X is clamped between the support groove 15 and the rail surface 25, the support portion 11 forming the support groove 15 and the rail surface 25 do not come into direct contact, and a gap is formed between them. This makes it easier to clamp the long medical instrument X between the inner surface 15a of the support groove 15 and the rail surface 25. On the other hand, if the depth D of the support groove 15 is too small, the long medical instrument X is likely to fall out of the support groove 15 when it is rotated. In this embodiment, the depth D of the support groove 15 can be adjusted to an appropriate range by adjusting the length of the side surface 17 in a cross-sectional view perpendicular to the extension direction of the support groove 15. Specifically, the length of the side surface 17 in the above cross-sectional view is preferably 0.3 mm to 0.4 mm if the long medical device X is a guiding catheter and the diameter of the base surface 16 is 2.0 mm or more and 3.0 mm or less, and preferably 0.1 mm to 0.25 mm if the long medical device X is a guide wire and the diameter of the base surface 16 is 0.4 mm or more and 0.45 mm or less.

[0040] Furthermore, it is preferable that the depth D of the second support groove 15 is greater than the depth D of the first support groove 15. As described above, the second support groove 15 is used when transmitting a large rotational torque to a long medical instrument X. Therefore, by making the depth D of the second support groove 15 greater than the depth D of the first support groove 15, it is possible to reliably prevent the long medical instrument X from falling out of the second support groove 15 when transmitting a large rotational torque to the long medical instrument X using the second support groove 15.

[0041] As shown in Figure 3, the rail surface 25 of this embodiment is composed of a flat surface without irregularities. This allows for smooth rotation of the long medical instrument X.

[0042] As shown in Figure 1 and other figures, the rail surface 25 of this embodiment is positioned only in the region corresponding to the area between the fingertip and the first joint (first region A1).

[0043] As shown in Figures 2 and 3, the support groove 15 in this embodiment is positioned to correspond to the pads of the fingers. The rail surface 25 in this embodiment is also positioned to correspond to the pads of the fingers. By arranging the support groove 15 and the rail surface 25 in this manner, it becomes easier to grip the long medical instrument X between the inner surface 15a of the support groove 15 and the rail surface 25, and it also becomes easier to rotate the long medical instrument X.

[0044] Examples of materials for forming the support portion 11 with support grooves 15 include hard plastic materials such as polycarbonate, polypropylene, polyethylene, and polystyrene. Furthermore, in order to reduce the coefficient of friction, it is preferable that the inner surface 15a of the support grooves 15 is coated with PTFE or the like. Examples of materials for forming the rail portion 21 with rail surface 25 include elastic materials such as butyl rubber, NBR (nitrile rubber), hydrogenated NBR, chloroprene rubber, and epichlorohydrin rubber.

[0045] As shown in Figure 2, the treatment aid 1 of this embodiment is equipped with a plurality of first covering parts 10 (two in this embodiment). The plurality of first covering parts 10 include an index finger covering part 10 positioned to cover the index finger and a middle finger covering part 10 positioned to cover the middle finger. The second covering part 20 is positioned to cover the thumb. In this way, the operation of rotating the long medical instrument X can be performed using combinations of fingers suitable for the operation, such as the thumb and index finger, and the thumb and middle finger. Furthermore, by positioning the first covering parts 10 with support grooves 15 at positions corresponding to the index finger and middle finger, it becomes easier to perform delicate operations on the long medical instrument X.

[0046] The therapeutic aids relating to this disclosure are not limited to the specific configurations shown in the embodiments and modifications described above, and various modifications, changes, and combinations are possible as long as they do not depart from the scope of the claims.

[0047] For example, in the embodiment described above, the treatment aid 1 is a glove in which the first covering portion 10 and the second covering portion 20 are integrally formed, but it is not limited to this. As shown in the modified example in Figure 13, the first covering portion 10 and the second covering portion 20 may be formed as separate parts. The treatment aid 100 shown in Figure 13 comprises a finger-cot-shaped first covering body 110 having the first covering portion 10, and a finger-cot-shaped second covering body 120 having the second covering portion 20. In this way, the movement of the user's hand H is less likely to be hindered even when the treatment aid 1 is worn.

[0048] Furthermore, in the embodiments described above, the rail surface 25 is composed of a flat surface, but is not limited to this. For example, the rail surface 25 may have small grooves formed therein that do not allow the long medical instrument X to get stuck.

[0049] Furthermore, in the embodiments described above, the treatment aid 1 comprises two first covering portions 10, but is not limited thereto. The treatment aid may be configured to have only one first covering portion 10, or to have three or more.

[0050] Furthermore, in the above-described embodiment, the first covering portion 10 is positioned to cover the index finger and middle finger, and the second covering portion 20 is positioned to cover the thumb, but the invention is not limited to this. For example, the first covering portion 10 may be positioned to cover fingers other than the index finger and middle finger. Also, the second covering portion 20 may be positioned to cover fingers other than the thumb.

[0051] Furthermore, in the embodiments described above, the support groove 15 is positioned to correspond to the pad of the finger, but is not limited to this. The support groove 15 may be positioned to correspond to the side of the finger, or to correspond to both the pad and the side of the finger.

[0052] Furthermore, in the embodiments described above, the rail surface 25 is positioned to correspond to the pads of the fingers, but is not limited to this. The rail surface 25 may be positioned to correspond to the sides of the fingers, or to correspond to both the pads and sides of the fingers.

[0053] Furthermore, in the embodiments described above, the support groove 15 is located in both the first region A1 and the second region A2, but is not limited to this. The support groove 15 may be located in only one of the first region A1 and the second region A2. Also, the support groove 15 may be located only in the region corresponding to the area between the second and third joints of the fingers (hereinafter simply referred to as the "third region"), or it may be located in multiple regions from the first region A1 to the third region A3.

[0054] Furthermore, in the embodiment described above, the rail surface 25 is located only in the first region A1, but is not limited to this. The rail surface 25 may be located in the second region A2 or the third region, or in multiple regions from the first to third regions A1.

[0055] Furthermore, in the above-described embodiment, the inner surface 15a of the support groove 15 comprises a semicircular bottom surface 16 and side surfaces 17 rising from both ends of the bottom surface 16 along the thickness direction of the support portion 11 in a cross-sectional view perpendicular to the extending direction of the support groove 15, but is not limited to this. For example, the inner surface 15a of the support groove 15 may consist only of a semicircular bottom surface 16 in a cross-sectional view perpendicular to the extending direction of the support groove 15. Also, the shape of the bottom surface 16 in the above cross-sectional view may be a shape other than a semicircle. For example, the shape of the bottom surface 16 in the above cross-sectional view may be a curved shape following an ellipse or an angular shape following a polygon, etc.

[0056] Furthermore, in the embodiments described above, the first covering portion 10 forms a thicker portion at the location of the support portion 11 than other portions, but it is not limited to this. For example, the maximum thickness of the portion where the support portion 11 is located in the first covering portion 10 may be the same as the maximum thickness of other portions. Also, for example, the maximum thickness of the portion where the support portion 11 is located in the first covering portion 10 may be smaller than the maximum thickness of other portions.

[0057] Furthermore, in the embodiments described above, the second covering portion 20 forms a thicker portion at the location of the rail portion 21 than other portions, but is not limited to this. For example, the maximum thickness of the portion of the second covering portion 20 where the rail portion 21 is located may be the same as the maximum thickness of other portions. Also, for example, the maximum thickness of the portion of the second covering portion 20 where the rail portion 21 is located may be smaller than the maximum thickness of other portions.

[0058] Furthermore, while the glove as the treatment aid 1 in the above-described embodiment is configured to be worn on the right hand H, it is not limited to this. The glove as the treatment aid 1 may also be configured to be worn on the left hand H. [Industrial applicability]
