Description

  The present invention relates to a catheter deformation device for deforming the shape of the distal end portion of a catheter and a catheter deformation device kit including the same.

  A catheter, which is a medical instrument, has a long shaft and a hub at the proximal end. Since the shaft is inserted into the living body lumen, it is made of a flexible material. The catheter is inserted to the position of the lesioned part of the living body lumen at the distal end. Various types of catheters are prepared according to the site of the biological lumen to be placed.

  There are various types of catheters provided as existing products, but the types are limited, and depending on the situation such as the shape of the vicinity of the lesion in the body lumen and the state of the lesion, the operator can The tip shape of the catheter may be deformed. As a device for deforming the distal end shape of the catheter, for example, there is a device described in Patent Document 1.

JP 2007-117389 A

  The device of Patent Document 1 is for temporarily setting the distal end of a shaped catheter to a predetermined other shape with a wire. It is not for changing the shape of the tip.

  For example, the following method is employed as a method for appropriately deforming the distal end shape of the catheter. In the first method, the surgeon is bent by hand so that the operator wants to deform the catheter, and the bent portion is heated with a heat gun or the like to fix the shape. In the second method, the operator inserts a guide wire into the distal end of the catheter, bends it into a desired shape, and further heats to fix the shape.

  However, even if the distal end shape of the catheter is deformed by hand, the shape of the flexible catheter shaft returns to some extent, so that it is difficult to obtain a desired shape. In particular, since the rigidity of the catheter varies depending on the type of the catheter, skill is required to make the distal end shape of the catheter a desired shape, and reproducibility is low. In the first method, it is necessary to perform heating while holding the deformed catheter by hand, which is difficult to work. Furthermore, in the second method, since the guide wire is heated while being inserted into the catheter, the used guide wire cannot be used thereafter.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a catheter deformation device that can easily and reliably deform the distal end shape of the catheter into a desired shape, and a catheter deformation device kit including the same. And

A catheter deformation device according to the present invention that achieves the above object has a device body having a deformation guide portion for fitting the distal end portion of the catheter,
The deformation guide portion has a bending portion that bends the distal end portion of the fitted catheter, and the bending portion has a desired bending portion when the catheter is removed from the deformation guide portion. It has a shape that becomes a shape.

  In the catheter deformation device kit according to the present invention that achieves the above object, the catheter deformation device and a core metal inserted from the distal end side into the catheter are sterilized and sealed in a packaging bag.

  The catheter deformation device configured as described above has a deformation guide portion for fitting the distal end portion of the catheter to the device main body. Therefore, the distal end portion of the catheter is deformed and fitted in accordance with the deformation guide portion for a predetermined time. By maintaining the shape, the distal end portion of the catheter can be deformed into a predetermined shape with good reproducibility. In addition, since the catheter is deformed by being taken out after a predetermined time while the distal end portion of the catheter is fitted to the deformation guide portion, it is not necessary to keep the hand held by the operator until the catheter is deformed. For this reason, work efficiency can be improved and deformation work can be performed safely. Moreover, the distal end portion of the catheter can be deformed not only in a two-dimensional shape but also in a three-dimensional shape.

  The deformation guide portion includes a groove-shaped portion formed on a first plane of the device body, and the groove-shaped portion includes a linear portion having an end portion of the first plane as a base end, and the linear portion. And the bent portion continuous from the tip of the. Since the deformation guide portion has a groove shape, the distal end portion of the catheter can be easily fitted into the deformation guide portion, and the deformation work can be facilitated.

  The groove-shaped part has a cored bar groove part in which a cored bar inserted from the distal end side with respect to the catheter is placed at the distal end part. For this reason, with the core metal inserted into the catheter, the core metal protruding from the distal end of the catheter can be fitted into the device body, and the distal end portion of the catheter can be reliably shaped by the core metal.

  If the groove-like portion is branched into a plurality on the distal end side from the linear portion and has a plurality of bent portions having different radii of curvature, the deformed shape of the distal end portion of the catheter can be selected. A part can be made into the shape according to the condition more.

  The device main body includes a base member having the first plane and a cover member having a second plane that can be opposed to the first plane, and the second plane covers the first plane; The cover member can be opened and closed with respect to the base member so that the state where the first plane is exposed can be switched. Therefore, the distal end portion of the catheter can be easily sandwiched and deformed by fitting the distal end portion of the catheter to the deformation guide portion of the base member and then closing the cover member.

  The second plane has a second groove-shaped portion so as to face the groove-shaped portion, and the catheter is sandwiched and fitted between the groove-shaped portion and the second groove-shaped portion, The catheter can be held from both sides with a groove, and the catheter can be deformed while maintaining an appropriate cross-sectional shape.

  The second plane has a convex part so as to face the groove part, and the catheter is sandwiched between the groove part and the convex part so that the catheter can be seen from both sides. It can hold | maintain with a groove-shaped part and a convex-shaped part, and can be made to deform | transform reliably.

  If the groove-like portion has a convex portion that protrudes toward the center of the groove at the edge portion, it is possible to suppress lifting when the catheter is fitted into the groove-like portion.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the dimension ratio of drawing is exaggerated on account of description, and may differ from an actual ratio. In the present specification, the side of the catheter 10 that is inserted into the living body lumen is referred to as “tip” or “tip side”, and the proximal side for operation is referred to as “base end” or “base end side”.

  The catheter deformation device 1 of this embodiment is used for deforming the shape of the distal end portion 31a of the catheter 30 used for medical purposes. As shown in FIG. 1, the catheter deformation device 1 has a device body 10 in which a cover member 12 can be opened and closed with respect to a base member 11. The device body 10 has a hinge portion 13 so as to span the base member 11 and the cover member 12, and the cover member 12 can be opened and closed with respect to the base member 11 by the hinge portion 13.

  The base member 11 of the device main body 10 has a groove-like portion 21 as a deformation guide portion into which the distal end portion 31a of the catheter 30 can be fitted. The groove-shaped portion 21 is formed on the first plane 20 that is one surface of the base member 11. The groove-shaped portion 21 includes a straight portion 21a having the end portion of the first plane 20 as a base end, a bent portion 21b bent in a substantially U shape continuous from the tip of the straight portion 21a, and a tip portion of the bent portion 21b. It has a continuous cored bar groove 21c. The straight portion 21a and the bent portion 21b are formed in a groove shape slightly wider than the shaft 31 of the catheter 30 to be fitted and slightly deeper than the outer diameter of the shaft 31. Further, the straight portion 21a and the bent portion 21b have the same width and depth over the entire length.

  The second plane 25 that faces the first plane 20 when the cover member 12 is closed is formed in a planar shape. Further, the second plane 25 has locking projections 26 that can be locked to concave locking portions 22 formed at the four corners of the first plane 20 at the four corners.

  As the material of the base member 11 and the cover member 12 forming the device body 10, a resin material or a metal material can be used. Moreover, you may provide a metal membrane | film | coat on the surface of the groove-shaped part 21, making a material the resin material. When a metal film is provided on the surface of the groove-shaped portion 21, when the shaft 31 fitted to the groove-shaped portion 21 is heated by heating the device body 10, heat is efficiently transmitted to the shaft 31. Can do. Moreover, also when the base member 11 and the cover member 12 are formed with a metal material, thermal conductivity can be made favorable.

  As shown in FIG. 2, when the cover member 12 is closed, the first plane 20 of the base member 11 and the second plane 25 of the cover member 12 come into contact with each other. At this time, the groove portion 21 of the base member 11 is closed by the second plane 25. Further, the locking protrusion 26 of the cover member 12 is locked to the locking portion 22 of the base member 11.

  Next, a process of deforming the distal end portion 31a of the catheter 30 will be described. As shown in FIG. 3, the catheter 30 in which the distal end portion 31 a is deformed has a long shaft 31. The shaft 31 is a hollow tubular body, and is formed of a material having a certain degree of flexibility. Examples of such a material include polyolefins such as polyethylene, polypropylene, polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ionomer, or a mixture of two or more thereof, soft polyvinyl chloride resin, Examples include polyamides, polyamide elastomers, polyesters, polyester elastomers, polyurethanes, thermoplastic resins such as fluorine resins, silicone rubbers, latex rubbers, etc., and combinations of one or more of these (polymer alloys, polymer blends) , Laminates, etc.) can be used. As a result, the shaft 31 can be deformed in its entirety including the tip portion 31a.

  First, the core metal 2 is inserted into the shaft 31. The core metal 2 is a thin metal wire, and can be formed of stainless steel or copper. The core metal 2 has a length of about 10 cm and a diameter of about 0.5 mm. However, the length and the diameter are not limited to this, and the length and the diameter only have to be appropriate for deforming the tip portion 31a of the shaft 31.

  The cored bar 2 has a large-diameter part 41 having an outer diameter larger than the inner diameter of the shaft 31 at the tip of the cored bar body 40. The large diameter portion 41 only needs to be formed so that the tip end portion of the core metal 2 does not enter the hollow interior of the shaft 31, and the tip end portion of the core metal main body 40 is curved in a ring shape. The large diameter portion 41 is not limited to this shape, and may be another shape such as a ball shape or a knot shape.

  The cored bar 2 is inserted into the hollow interior along the length direction from the side opposite to the large-diameter part 41 with respect to the tip part 31a of the shaft 31. Since the diameter of the cored bar 2 is smaller than the inner diameter of the shaft 31, the cored bar 2 can be inserted into the hollow interior of the shaft 31. The distal end portion of the core metal 2 has a rounded shape (R shape) so as not to damage the inside of the shaft 31.

  When the metal core 2 is inserted into the shaft 31, the tip 31a of the shaft 31 is fitted into the device body 10 as shown in FIG. The tip portion 31a of the shaft 31 is deformed in advance so as to conform to the shape of the groove-shaped portion 21 that is a deformation guide portion. The deformation of the shaft 31 is performed by the operator applying force with his / her hands. The deformation is performed according to the shape of the bent portion 21b. Since the cored bar 2 is inserted into the hollow inside of the distal end portion 31a of the shaft 31, the distal end portion 31a can maintain a deformed shape even if the hand is released from the shaft 31.

  When the distal end portion 31 a of the shaft 31 is deformed, the surgeon fits the distal end portion 31 a to the groove-shaped portion 21. At this time, the tip end portion of the cored bar 2 inserted into the shaft 31 is stored in the cored bar groove 21c.

  When the shaft 31 is fitted into the groove 21, the cover 31 is closed as shown in FIG. 5 so that the shaft 31 is sandwiched between the groove 21 and the second plane 25. By maintaining this state for a certain period of time, for example, about 5 minutes, the tip portion 31a of the shaft 31 can be shaped.

  The device body 10 may be heated from the outside in a state in which the shaft 31 is fitted in the groove portion 21 and the cover member 12 is closed. As a heating means, a dryer or the like can be used, and other means may be used. For example, alcohol flames, clean hot water, steam and the like can be mentioned. By heating the device body 10, the shaft 31 fitted in the groove 21 can be heated, and the shaft 31 can be more easily deformed.

  When the cover member 12 is closed and a predetermined time has elapsed, the cover member 12 is opened, the shaft 31 is taken out, and the cored bar 2 is pulled out from the shaft 31. When the device main body 10 is heated, the cover member 12 is opened and the shaft 31 is taken out after the device body 10 is sufficiently cooled by cooling or water cooling. When the mandrel 2 is pulled out, the flexible shaft 31 tries to return to its original shape. However, since the shape is maintained for a predetermined time in a deformed state, the original shape is completely achieved. I will not return. As shown in FIG. 6, the tip 31a of the shaft 31 from which the cored bar 2 has been pulled out has a curved shape with a larger radius of curvature than the bent portion 21b, and has a desired shape. Further, when the device body 10 is heated, the tip portion 31 a of the shaft 31 is held by the device body 10 while being cooled. That is, since the shaft 31 is cooled after being heated while maintaining the deformed shape, the shaping can be made more reliable.

  Thus, since the device main body 10 has the groove-shaped portion 21 into which the shaft 31 is fitted, the shaft 31 is deformed according to this, and fitted to maintain the shape for a predetermined time. The tip 31a of the shaft 31 can be deformed into a predetermined shape with good reproducibility. Further, since the shaft 31 is deformed by being taken out after a predetermined time while being fitted to the groove-like portion 21 which is the deformation guide portion of the device body 10, it is necessary for the operator to continue to hold the shaft 31 by hand. There is no. For this reason, working efficiency can be improved.

  The catheter deformation device 1 is transported and stored in a sterilized and sealed state. As shown in FIG. 7, the catheter deformation device kit 4 includes a device body 10 and a cored bar 2 in a sealed packaging bag 3. When using the catheter deformation device 1, the packaging bag 3 is opened, the device main body 10 and the cored bar 2 are taken out, and the distal end portion 31a of the catheter 30 is deformed by the above-described procedure. The packaging bag 3 has a flat bag shape formed by overlapping two sheets and fusing (bonding, heat fusion, high frequency fusion, etc.) or adhering the peripheral edge thereof. The packaging bag 3 includes an opening portion 3a in which two sheets are separated, and the packaging bag 3 can be opened by picking and spreading each sheet.

  Next, the device body 50 of the second embodiment will be described.

The point which has the shape part 56 is the same as that of a 1st form. The device main body 50 of this embodiment is different from the first embodiment in that the groove-like portion 56 is branched at the bent portion.

  The groove-shaped portion 56 includes a straight portion 56a having the end portion of the first plane 55 as a base end, a first bent portion 56b bent in a substantially U shape continuous from the tip of the straight portion 56a, and a first bent portion 56b. And a cored bar groove 56c that is continuous from the tip of the core. Further, a curved second bent portion 56d having a smaller radius of curvature than the first bent portion 56b branches off from the bent portion of the first bent portion 56b, and a cored bar groove 56e is provided at the tip thereof. . Further, in the bent portion of the first bent portion 56b, a curved third bent portion 56f having a smaller radius of curvature than the second bent portion 56d branches off from the base end side of the second bent portion 56d, and the tip thereof The core is provided with a core bar groove 56g.

  In the groove-like portion 56, the tip portion 31a of the shaft 31 can be selectively fitted to any one bent portion. The bent portion to be fitted is selected depending on how the shape of the tip portion 31a of the shaft 31 is to be deformed. When the tip portion 31a is fitted to the first bent portion 56b of the groove-like portion 56, the tip portion 31a is deformed into the shape shown in FIG. When the distal end portion 31a is fitted to the second bent portion 56d of the groove-shaped portion 56, the distal end portion 31a is deformed into the shape shown in FIG. When the tip portion 31a is fitted to the third bent portion 56f of the groove-like portion 56, the tip portion 31a is deformed into the shape shown in FIG. As described above, since the groove-like portion 56 is branched from the straight portion 56a on the distal end side, a deformed shape of the distal end portion 31a of the shaft 31 can be selected, and the distal end portion 31a can be shaped more appropriately. it can.

In the device body 60 of this embodiment, a first groove 66 is formed on the first plane 65 of the base member 61, and a second groove 68 is formed on the second plane 67 of the cover member 62.

  The first groove-like portion 66 of the base member 61 is provided at a straight portion 66a having the end of the first plane 65 as a base end, a bent portion 66b continuous from the tip of the straight portion 66a, and a tip of the bent portion 66b. A core bar groove 66c, which is the same as in the first embodiment. The second groove portion 68 of the cover member 62 has a shape symmetrical to the first groove portion 66 and faces the first groove portion 66 when the cover member 62 is closed. For this reason, the second groove-like portion 68 has a straight portion 68a, a bent portion 68b, and a core metal groove portion 68c in the same manner as the first groove-like portion 66.

  When the tip 31a of the shaft 31 is fitted into the first groove 66 and the cover member 62 is closed, the shaft 31 is divided into a first groove 66 and a second groove 68 as shown in FIG. Sandwiched. As described above, the groove-shaped portion may be formed on both the first plane 65 and the second plane 67.

  Further, in the present embodiment, a convex portion 69 may be formed on the second plane 67 instead of the second groove portion 68. The shape of the convex portion 69 in the length direction is the same as that of the second groove-shaped portion 68. In this case, as shown in FIG. 12, the tip 31 a of the shaft 31 fitted in the first groove 66 is sandwiched between the first groove 66 and the convex 69 when the cover member 62 is closed. It is.

  In the groove-like portion 76, a plurality of convex portions 76a are formed along the length direction. The convex portion 76a is formed so as to protrude from the edge of the groove-like portion 76 toward the center of the groove. The convex portions 76 a are alternately formed on one edge and the other edge of the groove portion 76 along the length direction of the groove portion 76.

  When the tip portion 31a of the shaft 31 is fitted into the groove portion 76, the convex portion 76a formed in the groove portion 76 comes into contact with the shaft 31, as shown in FIG. Thereby, when the shaft 31 is fitted into the groove-like portion 76, the shaft 31 can be prevented from being lifted. Note that the number and interval of the convex portions 76a can be set as appropriate.

  As described above, the catheter deformation device 1 according to the present embodiment has the device body 10 having the deformation guide portion for fitting the distal end portion 31 a of the catheter 30, and the deformation guide portion is formed of the fitted catheter 30.
