  The tube body 52 has a flexible tubular structure. For example, a polyolefin resin (for example, polyethylene or polypropylene), a polyamide resin (for example, nylon), a polyester resin (for example, PET), or an aromatic polyether. It can be composed of a synthetic resin such as a ketone resin (for example, PEEK), a polyether polyamide resin, a polyurethane resin, a polyimide resin, and a fluororesin (for example, PTFE, PFA, ETFE). The axial length of the tube body 52 is several to several tens of times longer than the length of the handle in the same direction, and is, for example, about 500 mm to 1200 mm. The outer diameter of the tube body 52 may be about 0.6 mm to 3 mm, for example.

  The tube body 52 has a lumen, and may be either a single lumen structure having one lumen therein or a multi-lumen structure having a plurality of lumens. For example, a lead wire connected to an electrode or a wire to be described later is disposed in the lumen. There may be one wire or a plurality of wires arranged in the lumen of the tube body 52.

  A plurality of electrodes 53 are provided at a distance from the distal side of the tube body 52. In FIG. 1, a tip electrode 53A and a plurality of ring electrodes 53B are provided. In an electrode catheter, this electrode is brought into contact with the inner wall of the patient's heart to measure arrhythmia and treat the heart. The electrode 53 can be comprised from metal materials, such as copper, gold | metal | money, platinum, aluminum, iron, or these alloys, for example. Note that the electrode 53 is preferably made of platinum or an alloy thereof in order to improve the contrast of X-rays when using the catheter.

For example, the wire 6 is made of metal wire such as stainless steel, carbon steel, nickel titanium alloy, polyamide resin (for example, nylon), polyolefin resin (for example, Polyethylene and polypropylene), polyester resin (for example, PET), aromatic polyetherketone resin (for example, PEEK), polyimide resin, fluorine resin (for example, PTFE, PFA, ETFE), etc. Can be used. The diameter of the wire 6 can be, for example, about 100 μm to 500 μm.

  Details of the catheter handle (first configuration example) will be described with reference to FIGS. 2 shows a plan view of the main part of the handle provided on the catheter shown in FIG. 1, FIG. 3 shows a plan view of the internal structure of the main part of the handle shown in FIG. 2, and FIG. 2 represents a cross-sectional view taken along IV-IV of the main part of the handle shown in FIG. 2, FIG. 5 represents a cross-sectional view taken along VV of the main part of the handle shown in FIG. 2, and FIG. FIG. 7 shows a plan view when the wire guide member of the main part of the handle shown in FIG. 2 is rotated with respect to the plane direction of the turntable.

  The handle 1 (1A) includes a handle main body 2, a turntable 3 provided so as to be rotatable with respect to the handle main body 2, and a wire guide member 7 formed to be rotatable with respect to the plane direction of the turntable 3. Have. In the handle, the plane direction means a direction perpendicular to the extending direction (rotation axis direction) of the rotation shaft 5 of the turntable 3. The planar direction has a main direction from the proximal side to the distal side of the handle and a width direction perpendicular to the main direction.

  The handle main body 2 is a member that supports the turntable 3, and the user usually holds the handle main body 2 and operates the handle. In the handle shown in the drawing, the handle main body 2 is configured to include a support portion of the rotating disk 3, a handle gripping portion, and a connection portion with the tube body 52. In the handle body 2, the support part of the turntable 3 means a part where the handle body 2 overlaps the turntable 3, and a part proximal to the handle part is a handle grip part, and a part distal to the handle part 2. Is a connection portion with the tube body 52. 4 and 5, the support portion of the handle main body 2 is provided only on one side in the direction of the rotation axis, but may be provided so as to sandwich the rotation plate 3 from both sides in the direction of the rotation axis. Good. The handle body 2 can be formed from, for example, a synthetic resin.

  The turntable 3 is provided so as to be rotatable with respect to the handle body 2, and the proximal side of the wire 6 is disposed. It is preferable that the turntable 3 is configured as a casing, and the wire guide member 7 and the wire 6 are disposed therein. The turntable 3 is provided with the insertion portion 13 of the wire 6 on the distal side, and the proximal side of the wire 6 is introduced into the turntable 3 through the insertion portion 13. The proximal side of the wire 6 is fixed to a wire locking portion 4 provided on the turntable 3. The wire locking portion 4 is preferably provided on the proximal side of the turntable 3. The turntable 3 can be made of, for example, a synthetic resin, and may be made of a transparent or translucent material so that the position of the wire guide member 7 can be seen from the outside of the turntable 3.

  The turntable 3 may be provided with the wire 6 only on one side with the rotation shaft 5 of the turntable 3 interposed therebetween, or may be provided on both sides. That is, the handle 1 may be for a single-direction type catheter that bends the distal side of the tube body 52 in one direction, or for a bi-direction type catheter that bends the distal side of the tube body 52 in two directions. May be. In the drawing, two wire locking portions 4 are provided on the turntable 3, but only one wire locking portion 4 may be provided.

  The wire guide member 7 defines the path of the wire 6 in the turntable 3. The wire 6 is disposed in contact with the outer edge of the wire guide member 7. By providing the wire guide member 7, when the turntable 3 is rotated, the path of the wire 6 in the turntable 3 is changed, and the wire 6 disposed in the lumen of the tube body 52 is moved to the proximal side. Can be towed. For example, by rotating the turntable 3 clockwise as shown in FIG. 6, the distance of the right wire 6R in the turntable 3 as viewed from the proximal side of the handle increases, and the wire 6R is moved to the proximal side. Can be towed to. By pulling the wire 6 in this way, the distal side of the tube body 52 can be bent. For example, in FIG. 1, by rotating the turntable 3 clockwise, the distal side of the tube body 52 is bent to the right, and by rotating the turntable 3 counterclockwise, the distal side of the tube body 52 Can be bent to the left. The rotation angle (rotatable angle range) of the turntable 3 is preferably 45 ° or more, more preferably 60 ° or more, more preferably 150 ° or less, and 120 ° from the viewpoint of improving the operability of the catheter or handle. The following is more preferable.

  In the handle 1 </ b> A, a wire guide member 7 is provided in the rotating disk 3, and the wire guide member 7 has a rotating disk 3 (specifically, a part of the rotating disk 3 is viewed from both sides in the rotating axis direction in a cross section in the rotation axis direction). It is sandwiched between the rotating plates 3A and 3B). The rotating disc 3A located on one side (lower side in FIG. 4) in the direction of the rotating shaft is connected by the handle body 2 and the rotating shaft 5 provided adjacent to each other, and the rotating disc 3 is one side in the direction of the rotating shaft. Is supported by the handle body 2. The rotating shaft 5 is constituted by a screw, and the screw passes through the wire guide member 7, the lower rotating disk 3 </ b> A and the handle body 2, and is fastened by a nut from the handle body 2 side. The screw of the rotating shaft 5 may be fitted into a screw hole formed in the handle body 2. In addition, the rotating shaft 5 is not limited to the combination of a screw and a nut, For example, you may employ | adopt a pin and pinning. Moreover, the position of a screw and a nut may be reversed.

  The wire guide member 7 is formed to be rotatable with respect to the plane direction of the turntable 3. In the handle 1 </ b> A, the rotating shaft 5 of the rotating disk 3 also serves as the rotating shaft of the wire guide member 7, and the rotating shaft 5 passes through the wire guide member 7 and the rotating disk 3. The rotation center of the wire guide member 7 is positioned so as to overlap the rotation shaft 5 of the turntable 3.

  The wire guide member 7 has an outer edge formed at an unequal distance from the rotation center of the wire guide member 7, and is operated from the outside of the handle 1 so that the turntable 3 is fixed and the plane direction of the turntable 3 is fixed. Is formed to be rotatable. That is, the wire guide member 7 is provided in a shape other than a circle centered on the rotation center, and the rotation position with respect to the rotation center can be adjusted by operating the wire guide member 7 from the outside of the handle 1. That the wire guide member 7 is rotatable with respect to the plane direction of the turntable 3 means that the wire guide member 7 can be rotated about a direction perpendicular to the plane direction of the turntable 3 as a rotation axis. Further, the fact that the wire guide member 7 is rotatable with the rotating plate 3 fixed means that the wire guide member 7 can be rotated even when the rotating plate 3 is fixed. It does not mean that it is essential to perform in a fixed state. By configuring the wire guide member 7 in this way, when the handle 1 is used, the amount of change in the path of the wire 6 in the turntable 3 when the turntable 3 is rotated can be adjusted.

  For example, the handle 1A shown in FIGS. 2 to 7 is provided with an oval-shaped wire guide member 7 in plan view, but the position of the wire guide member 7 is set in the width direction of the handle 1 as shown in FIG. When provided so as to be symmetrical with respect to the left and right, both the left wire 6L and the right wire 6R are within the turntable 3 regardless of whether the turntable 3 is rotated clockwise or counterclockwise. It is possible to prevent the amount of change in the road from changing. The position of the wire guide member 7 is determined with reference to the time when the turntable 3 is at the center position of the rotatable angular range. On the other hand, as shown in FIG. 7, the wire guide member 7 is asymmetric with respect to the width direction of the handle 1 (in FIG. 7, the long diameter portion of the wire guide member 7 is located on the right side when viewed from the proximal side of the handle. ), When the wire guide member 7 is rotated with respect to the plane direction of the turntable 3, the amount of change in the path of the left wire 6L is reduced when the turntable 3 is rotated, and the right wire 6R is reduced. The amount of change in the distance can be increased. As a result, the user (operator) can adjust the pulling length of the wire 6 when the turntable 3 is rotated, and the bending of the distal side of the tube body 52 when the turntable 3 is rotated is adjusted. The degree can be arbitrarily adjusted according to the user's preference and needs.

  In the handle 1A, the wire guide member 7 is formed so that the long diameter portion of the wire guide member 7 can be positioned on each of the right side and the left side when viewed from the proximal side of the handle. The wire guide member 7 may be configured to be rotatable so that the long diameter portion can be positioned on both one side and the other side in the width direction of the handle 1 as described above, and can be positioned only on one side in the width direction. It may be configured to be rotatable.

  The shape of the wire guide member 7 is not particularly limited as long as it has an outer edge formed at an unequal distance from the center of rotation of the wire guide member 7. Examples include a circle and a circle whose center is other than the center of rotation. The wire guide member 7 is preferably formed in a line-symmetric shape, and the center of rotation is preferably located on a line-symmetrical symmetry axis, so that the turntable 3 is rotated counterclockwise as compared with the case where the turntable 3 is rotated clockwise. It is possible to create a state where the wire 6 can be operated in the same manner when it is rotated. In addition, it is preferable that at least a part of the outer edge of the wire guide member 7 is formed in a curved shape, thereby suppressing the wire 6 from being caught on the wire guide member 7 and making the operation of the turntable 3 smooth. be able to. The wire guide member 7 can be formed from a synthetic resin, for example.

  The wire guide member 7 may be directly or indirectly attached to the turntable 3 and may be formed so as to rotate together with the turntable 3 by rotation of the turntable 3. It may be attached and formed so as not to rotate together with the turntable 3 by the rotation of the turntable 3. In either case, the wire guide member 7 can be formed so as to be rotatable with respect to the plane direction of the turntable 3 while the turntable 3 is fixed. In the handle 1 </ b> A shown in FIGS. 2 to 7, the wire guide member 7 is attached to the rotating disk 3 and is configured to rotate together with the rotating disk 3.

  In order for the wire guide member 7 to be formed to be rotatable with respect to the plane direction of the turntable 3 with the turntable 3 fixed by operating from the outside of the handle 1, for example, An operation unit may be provided. In the handle 1A, an operation portion 8 is provided on the wire guide member 7, and the operation portion 8 is exposed to the outside of the handle 1A. Specifically, the operation unit 8 is provided in the wire guide member 7, and a groove 9 is formed in the rotating disk 3 (in FIG. 4 and FIG. 5, the rotating disk 3 </ b> B located on the upper side of the drawing). Is provided. The operation portion 8 is provided at a position other than the rotation center of the wire guide member 7, the groove 9 is formed in an arc shape, and the operation portion 8 is rotated from the outside of the handle 1 </ b> A by rotating along the groove 9. The member 7 can be rotated with respect to the plane direction of the turntable 3.

  The operation part should just be extended and provided from the wire guide member 7, and the form is not specifically limited. In the handle 1A, the operation portion 8 is provided so as to protrude from the wire guide member 7 in the direction of the rotation axis. In addition to this, for example, an operation portion is provided so as to protrude from the wire guide member 7 in the plane direction. The operation unit may be provided so as to be exposed from the side surface of the turntable 3. In this case, a groove (the groove may be a gap between the rotating disk 3A and the lower rotating disk 3B) is formed on the side surface of the rotating disk 3, and the operation unit may be provided through the groove. Further, as will be described later, instead of providing an operation portion on the wire guide member 7, the wire guide member 7 is formed to be rotatable with respect to the plane direction of the turntable 3 by operating from the outside of the handle 1 by a gear mechanism. You can also

  The operation unit 8 may be formed integrally with the wire guide member 7 or may be attached to the wire guide member 7 as a separate member from the wire guide member 7. It is preferable that the operation portion 8 extends through the groove 9 of the rotating disk 3 and further extends by 0.5 mm or more so that it can be easily operated by hand from the outside of the handle 1A, and preferably extends by 1 mm or more. Is more preferable. Further, in order to improve the operability of the operation unit 8, a handle 8 </ b> A may be provided on the top of the operation unit 8 as shown in FIG. 5. In this case, the handle portion 8A constitutes a part of the operation portion 8, and is preferably formed wider than the main body portion of the operation portion 8 (a portion closer to the wire guide member 7 than the handle portion 8A).

  The groove 9 penetrates the turntable 3 and is provided in an arc shape centered on the rotation center of the wire guide member 7. At this time, the extending angle of the arc of the groove 9 is preferably 30 ° or more, more preferably 45 ° or more, further preferably 60 ° or more, more preferably 270 ° or less, more preferably 210 ° or less, and 180 ° or less. Is more preferable. The groove 9 may be partially formed with a narrow width so that the operation unit 8 can be easily fixed at a desired position.

  In the handle 1 </ b> A, an opening 12 is formed in a portion overlapping the rotating shaft 5 of the rotating disk 3 </ b> B located above the wire guide member 7, and the screw of the rotating shaft 5 can be turned from the opening 12. By tightening or loosening the screws and nuts, the wire guide member 7 is fixed to the turntable 3A located below the wire guide member 7, or the wire guide member 7 is moved away from the turntable 3A in the plane direction of the turntable 3. In contrast, it can be made rotatable. That is, the wire guide member 7 is formed so as to be movable from the outside of the handle 1 in the direction of the rotation axis of the turntable 3. If the wire guide member 7 is configured in this way, the handleability of the handle 1 can be improved.

  Another embodiment (second configuration example) of the catheter handle will be described with reference to FIGS. 8 is a plan view of the main part of the catheter handle, FIG. 9 is a plan view of the internal structure of the main part of the handle shown in FIG. 8, and FIG. 10 is a plan view of the main part of the handle shown in FIG. XX sectional drawing is represented. In the following description, the description of the same part as above is omitted. 8 to 10, the same components as those in the above drawings are represented by the same reference numerals.

  In the handle 1 (1B) shown in FIGS. 8 to 10, the planar shape of the wire guide member 7 is different from that of the handle 1A, and is provided in a circular planar shape. However, the center of the circle is provided so as to deviate from the rotation center of the wire guide member 7 (corresponding to the rotation shaft 5 of the turntable 3).
