Description

The present invention relates to a holder for holding a medical elongated device.

In endovascular treatment, various long medical devices such as guide wires and catheters are used. During an endovascular treatment procedure, the operator may remove the guidewire outside the body and reinsert it into the blood vessel. The guidewire that has been removed from the body is coiled and temporarily stored in a liquid-filled container until it is reinserted.

The proximal end of the guidewire is made of a material with high rigidity and elasticity. This may cause the guidewire to attempt to return from its coiled state to its straight state, causing it to inadvertently pop out of the liquid-filled container and become contaminated. Therefore, means for holding the guide wire in a coiled state has been proposed.

Patent Document 1 discloses a fixator configured to allow insertion of a wire in a direction perpendicular to the longitudinal direction of the wire. This fixator can fix the wire with a gripping part that includes a first stop part formed on one side of the shaft of the wire and a second stop part formed on the other side.

JP2021-115220A

In order to hold the elongated device in a fixator like Patent Document 1, the distance between the first stop portion and the second stop portion of the gripping portion needs to be smaller than the outer diameter of the elongated device. Therefore, when inserting the elongated device between the first stop part and the second stop part of the gripping part, when the elongated device is pushed downward from above the fixator, the surface of the elongated device It moves while rubbing against the surface of the grip. For this reason, the hydrophilic coating applied to the outer peripheral surface of the elongated device may peel off. Peeling of the hydrophilic coating reduces the surface lubricity of the elongated device, which may reduce the functions of the elongated device, such as ease of insertion into the blood vessel and operability within the blood vessel.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a holder that can firmly hold an elongated device while suppressing deterioration in the function of the elongated device.

A distance between a surface of the first rotating body and a surface of the second rotating body in a cross-sectional view perpendicular to the longitudinal direction of the elongated device is smaller than a maximum outer diameter of the elongated device.

The holder configured as described above can hold the elongated device by sandwiching it between the first rotating body and the second rotating body. When inserting the elongated device between the first rotating body and the second rotating body, the first rotating body and the second rotating body each rotate as the elongated device moves toward the bottom wall. Therefore, the elongated device is held by the first rotating body and the second rotating body without the surface rubbing against the surface of each rotating body. Therefore, the holder is less likely to peel off the hydrophilic coating of the elongated device due to contact with the holder, and can firmly hold the elongated device while suppressing deterioration in the function of the elongated device.

(3) In the holder according to (2) above, the first rotating body has an arc shape on the opposite side in the circumferential direction from the first holding surface, and the second rotating body has an arc shape on the opposite side in the circumferential direction from the second holding surface. The sides may be arcuate. Thereby, the holder can reduce the maximum rotation radius of the surfaces of the first rotating body and the second rotating body facing the main body, so that the main body can be made smaller.

(4) In the holder of (1) above, the first rotating body and the second rotating body may each have a cylindrical shape. Thereby, the holder can hold the elongated device without directing the first rotating body and the second rotating body in a specific direction before the holding part holds the guide wire.

(5) In the holder according to any one of (1) to (4) above, the support wall is arranged at both ends of the first rotation shaft and the second rotation shaft, and the support wall is arranged at both ends of the first rotation shaft and the second rotation shaft. The elongated device may include a notch portion for positioning the elongated device between the elongated device and the second rotating shaft. Thereby, since the holder can support the first rotating shaft and the second rotating shaft from both sides by the support walls, it is possible to stably rotate the first rotating body and the second rotating body.

(6) In any one of the holders (1) to (5) above, one or more of the first rotating body and the second rotating body may be provided, and two or more of the other may be provided. good. Thereby, the holder holds the guide wire at at least three locations along the longitudinal direction of the guide wire, so that the guide wire can be held stably.

The main body portion 20 can be made of metal or resin. The size of the main body portion 20 is formed in a range of 3 cm or more and 10 cm or less in both length and width. However, the main body portion 20 may have dimensions exceeding this dimension range.

The holding section 30 includes a first rotating body 40 and a second rotating body 50. Two first rotary bodies 40 are provided spaced apart from each other along the longitudinal direction of the guide wire 60 to be held. Each first rotating body 40 is rotatably supported with respect to a first rotating shaft 41. Two second rotating bodies 50 are provided spaced apart along the longitudinal direction of the guide wire 60 to be held. The second rotating bodies 50 are arranged at different positions from the first rotating bodies 40 along the longitudinal direction of the guide wire 60 to be held. Further, the first rotating body 40 and the second rotating body 50 are arranged alternately along the longitudinal direction of the guide wire 60 to be held. The second rotating body 50 is rotatably supported with respect to the second rotating shaft 51.

The first rotating body 40 has a planar first holding surface 42 that holds the guide wire 60 and an arcuate arc portion 43 on the opposite side in the circumferential direction from the first holding surface 42 . The first rotating body 40 has a planar side wall contact portion 44 and a bottom wall contact portion 45 between the first holding surface 42 and the circular arc portion 43, respectively. As shown in FIG. 2, the bottom wall contact portion 45 contacts the inner surface of the bottom wall 22 in a state where the holding portion 30 holds the guide wire 60. As shown in FIG. 3, the side wall abutting portion 44 abuts against the inner surface of the side wall 26 before the holding portion 30 holds the guide wire 60. As shown in FIG. The rotatable angle of the first rotating body 40 is limited from the angle at which the side wall abutting portion 44 abuts the inner surface of the side wall 26 to the angle at which the bottom wall abutting portion 45 abuts the inner surface of the bottom wall 22. .

The second rotating body 50 has a planar second holding surface 52 that holds the guide wire 60 and an arcuate arc portion 53 on the opposite side of the second holding surface 52 in the circumferential direction. The second rotating body 50 has a planar side wall contact portion 54 and a bottom wall contact portion 55 between the second holding surface 52 and the circular arc portion 53, respectively. As shown in FIG. 2, the bottom wall contact portion 55 contacts the inner surface of the bottom wall 22 in a state where the holding portion 30 holds the guide wire 60. As shown in FIG. 3, the side wall contact portion 54 contacts the inner surface of the side wall 26 before the holding portion 30 holds the guide wire 60. As shown in FIG. The rotatable angle of the second rotating body 50 is limited from the angle at which the side wall abutting portion 54 abuts the inner surface of the side wall 26 to the angle at which the bottom wall abutting portion 55 abuts the inner surface of the bottom wall 22. .

As shown in FIG. 2, when the holding part 30 holds the guide wire 60, the first holding surface 42 of the first rotating body 40 and the second holding surface 52 of the second rotating body 50 face in opposite directions. Turn. In a state where the holding part 30 holds the guide wire 60, the distance between the first holding surface 42 and the second holding surface 52 is smaller than the maximum outer diameter of the guide wire 60. That is, in a cross-sectional view perpendicular to the longitudinal direction of the guide wire 60, the distance between the first rotating body 40 and the second rotating body 50 while holding the guide wire 60 is smaller than the maximum outer diameter of the guide wire 60. The distance between the first rotating body 40 and the second rotating body 50 is preferably 0 mm or more and 1 mm or less. However, the distance between the first rotating body 40 and the second rotating body 50 may be outside this range as long as it is smaller than the maximum outer diameter of the guide wire 60.

As shown in FIG. 3, before the holding part 30 holds the guide wire 60, the bottom wall abutting part 45 of the first rotating body 40 and the bottom wall abutting part 55 of the second rotating body 40 are as follows. facing in opposite directions. Before the holding part 30 holds the guide wire 60, the distance between the bottom wall contact part 45 of the first rotating body 40 and the bottom wall contact part 55 of the second rotating body 40 is the maximum distance of the guide wire 60. smaller than the outer diameter. Therefore, when the operator pushes the guide wire 60 toward the bottom wall 22, the first rotating body 40 and the second rotating body 50 can be rotated.

The first rotating body 40 and the second rotating body 50 can be made of metal or resin. It is preferable that at least the surfaces of the first rotating body 40 and the second rotating body 50 that come into contact with the guide wire 60 are made of flexible resin. Examples of such resins include various rubber materials such as silicone rubber, natural rubber, and synthetic rubber, thermoplastic elastomers, and the like. However, the surfaces of the first rotating body 40 and the second rotating body 50 may be formed of materials other than these materials. In the holder 10, the surfaces of the first rotating body 40 and the second rotating body 50 are formed of a flexible material, so that when the guide wire 60 is held, the first rotating body 40 and the second rotating body Since the surface portion of 50 is elastically deformed, the holding force of guide wire 60 is improved.

The surfaces of the first rotating body 40 and the second rotating body 50 may have a surface shape that increases the frictional force generated between them and the surface of the guide wire 60. Such a surface shape can be formed, for example, by providing a pattern such as an uneven shape, a vertical striped shape, a horizontal striped shape, or by roughening the surface.

A method of using the holder 10 will be explained. Before using the holder 10, the operator previously coils the guide wire 60 to form a plurality of loops. Next, the operator rotates the first rotating body 40 and the second rotating body 50 to the state shown in FIG. 3. In a state before the holding part 30 holds the guide wire 60, the first rotating body 40 is arranged such that the side wall contact part 44 contacts the inner surface of the side wall 26 and the first holding surface 42 faces upward. . Furthermore, before the holding section 30 holds the guide wire 60, the second rotating body 50 is arranged such that the side wall contact section 54 contacts the inner surface of the side wall 26 and the second holding surface 52 faces upward. be done.

Next, the operator places the guide wire 60 between the first rotating body 40 and the second rotating body 50, and pushes the guide wire 60 downward. As a result, as shown in FIG. 4, the first rotating body 40 and the second rotating body 50 are pressed by the guide wire 60 and rotate in opposite directions. At this time, the first holding surface 42 of the first rotating body 40 tilts toward the center of the main body 20 where the guide wire 60 is located. Further, the second holding surface 52 of the second rotating body 40 is tilted toward the center of the main body portion 20 where the guide wire 60 is located.

When the operator further pushes the guide wire 60, as shown in FIG. 2, the first rotating body 40 stops as the bottom wall abutting portion 45 comes into contact with the inner surface of the bottom wall 22, and the second rotating body 50 stops as shown in FIG. The wall contact portion 55 comes into contact with the inner surface of the bottom wall 22 and stops. At this time, the first holding surface 42 of the first rotating body 40 and the second holding surface 52 of the second rotating body 50 face in opposite directions, and in a vertical cross-sectional view with respect to the longitudinal direction of the guide wire 60, Since the distance between the first holding surface 42 of the rotating body 40 and the second holding surface 52 of the second rotating body 50 is smaller than the maximum outer diameter of the guide wire 60, the guide wire 60 is It is held by the body 50. Thereby, as shown in FIG. 5, the holder 10 can hold the coiled guide wire 60.

When removing the guide wire 60 from the holder 10, the operator rotates the first rotating body 40 and the second rotating body 50 in opposite directions from the state shown in FIG. 2. At this time, the operator rotates the first rotating body 40 and the second rotating body 50 so that the first holding surface 42 and the second holding surface 52 face upward, respectively. Thereby, the first rotating body 40 and the second rotating body 50 are in the state shown in FIG. 4. When the operator further rotates the first rotating body 40 and the second rotating body 50, the side wall abutting portion 44 of the first rotating body 40 comes into contact with the inner surface of the side wall 26 and the second rotating body 50 stops. The contact portion 54 comes into contact with the inner surface of the side wall 26 and stops. As a result, as shown in FIG. 3, the guide wire 60 separates from the first rotating body 40 and the second rotating body 50, and the operator can remove the guide wire 60 from the holder 10. Note that when removing the guide wire 60 from the holder 10, the operator pulls up the guide wire 60 held by the first rotating body 40 and the second rotating body 50, thereby removing the guide wire 60 from the first rotating body 40. and the second rotating body 50 may be rotated in opposite directions.

Note that the guide wire 60 held by the holder 10 does not have to be wound into a coil. In this case, the operator presses one guide wire 60 against the first rotating body 40 and the second rotating body 50 and rotates the first rotating body 40 and the second rotating body 50 to rotate the guide wire 60. It can be held by the holder 10. Further, the operator can also press a plurality of guide wires 60 that are not wound into a coil shape together against the first rotating body 40 and the second rotating body 50 so that the holder 10 can hold them.

A modification of the holder will be explained. As shown in FIG. 6, the holder 70 according to the modification includes a main body 71 having a bottom wall 72 and a support wall 73, and a holder 74 including a first rotating body 75 and a second rotating body 77. . The first rotation shaft 76 and the second rotation shaft 78 are each supported by the support wall 73. When the operator pushes the guide wire 60 between the first rotating body 75 and the second rotating body 77, the guide wire 60 is held by the first rotating body 75 and the second rotating body 77.

Both the first rotating body 75 and the second rotating body 77 are formed in a cylindrical shape. Therefore, in the holder 70, there is no need to orient the first rotating body 75 and the second rotating body 77 in a specific direction before the holding part 30 holds the guide wire 60. The bottom wall 72 of the main body portion 71 has a recess 72a in which the lower portions of the first rotating body 75 and the second rotating body 77 are accommodated. Therefore, the rotation centers of the first rotating body 75 and the second rotating body 77 can be arranged closer to the bottom wall 72. Further, the bottom wall 22 has a convex portion 79 that is raised in the shape of a chevron at a central portion where the distance from the center position of the first rotating body 75 is equal to the distance from the center position of the second rotating body 77. The convex portion 79 is provided on the bottom wall 22 over the entire length between the pair of support walls 73 arranged opposite to each other. That is, the convex portion 79 is provided on the bottom wall 22 along the longitudinal direction of the guide wire 60 in a state where the holding portion 30 holds the guide wire 60. The concave portion 72a and the convex portion 79 of the bottom wall 72 reduce the space formed between the first rotary body 75 and the second rotary body 77 in a cross-sectional view perpendicular to the longitudinal direction of the guide wire 60 to be held. be able to. Thereby, the holding part 70 can suppress the guide wire 60 from entering the space formed between the first rotating body 75 and the second rotating body 77.

The holder 10 may have a fixing mechanism for fixing the holder 10 to an external object. As shown in FIG. 7, the fixing mechanism 80 provided on the holder 10 includes a holder fixing section 82 provided on the main body 20, and an external fixing section 83 having an adhesive surface 83a that is adhesively fixed to an external object. , has a wire-shaped connecting part 81 that connects the holder fixing part 82 and the external fixing part 83. The external object to which the external fixing part 83 is fixed is a container filled with liquid for storing the guide wire 60, a surgical drape, a surgical table, or the like. The external fixing part 83 is not limited to having the adhesive surface 83a, but may be a clip or the like that can hold an external object. The holder 10 having the fixing mechanism 80 can prevent the holder 10 holding the guide wire 60 from falling from a container or a surgical table. Moreover, the holder fixing part 82 and the external fixing part 83 may be formed so that they can be directly fitted without using the connecting part 81.

Further, the fixing mechanism of the holder 10 may have an adhesive surface on the outer surface of the bottom wall 22 that can be attached to another object. Further, the fixing mechanism of the holder 10 may have a portion that allows the lower part of the holder 10 and the other object to fit into each other.
