Description

  The present invention relates to a guide wire introduction tool and a guide wire introduction tool set for introducing a guide wire for guiding a catheter into a blood vessel, and more particularly, to guide wire introduction for introducing a guide wire whose tip is bent when unconstrained. The present invention relates to a tool and a guide wire introducing tool set.

  When a high concentration nutrient is infused into a patient, a catheter may be inserted into a vein close to the heart. Such a catheter requires a certain length, and a guide wire for guiding the catheter to a desired position is inserted in advance.

  In this case, first, it is confirmed that the syringe is flashed back by puncturing to puncture the vein, and a guide wire is inserted into the vein from a puncture device (see, for example, Patent Document 1) provided between the puncture needle and the syringe. To introduce.

  The puncture device has a bifurcated shape, and includes a linear main port and a side port that is connected to and communicates with the main port at an angle, and a puncture needle and a rear end of the main port at the tip of the main port And a guide wire supply tool is connected to the rear end of the side port. The side port is provided with a rubber hemostasis valve, and the guide wire is guided to the main port and the puncture needle through the hole of the hemostasis valve.

  The guide wire may be bent in a J shape or an L shape from the viewpoint of operability and the like. Such a bent guide wire is difficult to pass through the hole of the hemostasis valve, and moves toward the direction of the syringe (rear) instead of the direction of the puncture needle (front) when entering the main port from the side port within the puncture device. May end up. Further, when entering the main port from the side port in the puncture device, there is a risk of curling on the spot.

  Against this background, Patent Literature 2 proposes a guide wire insertion tool including an inner tube (guide 16 in Patent Literature 2) that guides the guide wire from the opening portion of the side port to the distal end opening portion of the main port. With such a guide wire insertion tool, it is possible to prevent the guide wire from moving in the reverse direction within the main port.

JP 2007-209 A JP-A-10-118192

  In the guide wire insertion tool described in Patent Document 2, the inner tube also has a certain inner diameter, and the tip of the J-shaped guide wire may be caught on the inner wall.

  Further, since the inner tube is always arranged in the main port, it becomes an obstacle, and the flow path of the flashback is restricted by the inner tube, so that the flashback takes time.

  Furthermore, when the flashed blood flows into the inner tube, there is a concern that the blood will coagulate if it takes time to puncture.

  Furthermore, the inner tube is manufactured and assembled separately from the main body of the puncture device, has a complicated structure, and is not easily assembled. When blood enters the gap between the inner tube and the main body, there is a possibility that the blood coagulates at that portion.

  Furthermore, the puncture device has a special shape for holding the inner tube, and a conventional product cannot be used. The inner tube is provided separately from the hemostasis valve, and the tip of the J-shaped guide wire hardly passes through the hemostasis valve.

  The present invention has been made in consideration of such problems, and has a simple configuration in a guide wire introduction tool and a guide wire introduction tool set for introducing a guide wire whose tip is bent when not restrained into a blood vessel. It is an object of the present invention to provide a guide wire introducing tool and a guide wire introducing tool set that allow a guide wire to easily pass through a hemostasis valve.

  A guide wire introducing tool according to the present invention includes a flexible guide wire whose tip is bent when not restrained, a first pipe that holds the guide wire in a lumen, and a part of the first pipe. A second pipe that is connected and spaced apart from the opening of the first pipe; and a tube that covers a part of the guide wire including the distal end portion and holds the distal end portion in a substantially linear shape, The guide wire extends from the opening of the first pipe, the tip is disposed in the second pipe, and the tube is disposed in the second pipe with the tip of the guide wire together with the tip of the guide wire. The rear end is disposed between the first pipe and the second pipe.

  In such a configuration, the guide wire is constrained in a substantially straight line by the tube, so that it easily passes through the hemostasis valve and is correctly guided from the side port to the front end opening of the main port. The puncture device to be applied has a simple configuration similar to that of the conventional product.

  The tip portion may be bent into a J shape when unconstrained.

  The guide wire introducing tool set according to the present invention is a guide wire introducing tool set having a guide wire introducing tool and a puncture tool, and the guide wire introducing tool is a flexible wire whose tip is bent when not restrained. Guide wire, a first pipe for holding the guide wire in a lumen, a second pipe connected to a part of the first pipe and spaced apart from an opening of the first pipe, A tube that covers a part of the guide wire including the distal end portion and holds the distal end portion in a substantially straight line, the guide wire extending from an opening of the first pipe, and the distal end portion Disposed in two pipes, and the tube has a distal end disposed in the second pipe together with the distal end portion of the guide wire, a rear end disposed between the first pipe and the second pipe, The puncture device is linear A main body including a main port, a side port connected to and obliquely connected to the main port, and to which a tip of the second pipe is mounted; and the guide wire can be inserted in a substantially central portion; It has a hemostasis valve that keeps the port fluid-tight and a puncture device that is connected to the tip of the main port.

  In such a configuration, since the guide wire is constrained in a substantially linear shape by the tube, it is easy to pass through the hemostasis valve and is correctly guided from the side port to the tip opening of the first pipe. The puncture device has a simple configuration similar to that of the conventional product.

  When the distal end of the second pipe is attached to the side port, the guide wire is fed out and the distal end reaches the distal end opening of the main port, the tube covers the guide wire in the puncture device over the entire length. It may be. With such a tube, the guide wire can be correctly guided in the puncture device and the puncture needle.

  When the distal end of the second pipe is attached to the side port, the guide wire is fed out and the distal end reaches the distal end opening of the main port, the rear end of the tube is connected to the first pipe and the second pipe. You may arrange | position between pipes. As a result, the tube has a length sufficient to guide the guide wire correctly in the puncture device.

  A stopper may be provided at the rear end of the tube so as to abut against the opening of the second pipe and restrict the lead-out of the tube. By providing such a stopper, the lead-out of the tube can be restricted at an appropriate position.

  The hemostasis valve includes a first cut that reaches one surface and a second cut that reaches the other surface, and the first cut and the second cut are connected to each other. It is easy to pass through and has high liquid-tightness.

  In the guide wire introducer and the guide wire introducer set according to the present invention, the guide wire is restrained substantially linearly by the tube, so that it can easily pass through the hemostasis valve and is correctly guided from the side port to the distal end opening of the main port. It is burned. The puncture device to be applied has a simple configuration similar to that of the conventional product.

  Hereinafter, a guide wire introduction tool 12 and a guide wire introduction tool set 10 will be cited as embodiments of the guide wire introduction tool and the guide wire introduction tool set according to the present invention, and will be described with reference to FIGS. .

  As shown in FIG. 1, the guide wire introduction tool set 10 includes a guide wire introduction tool 12 and a puncture tool 11. The puncture device 11 includes a Y hub (main body) 14, a syringe 16, and a puncture needle 18. It goes without saying that the guide wire introducing tool set 10 may include a dilator 60 and a catheter 70 described later, and other auxiliary tools. The guide wire introducing tool set 10 may be stored in a case and sterilized inside. The Y hub 14 and the syringe 16 are transparent bodies, and the internal blood can be confirmed.

  As shown in FIGS. 2 and 3, the guide wire introduction tool 12 is configured to hold a substantial portion including the rear end in the lumen except for the flexible guide wire 20 and the distal end portion 20 a of the guide wire 20. 1 pipe 22, a second pipe 24 that is connected to a part of the first pipe 22, is provided at both ends and is spaced from the opening 22 a of the first pipe 22, and a tube 26.

  The guide wire 20 is made of, for example, steel and is about 30 cm, and about 20 cm behind the guide wire 20 is inserted into the first pipe 22 in the initial state. The distal end portion 10a of the guide wire 20 has particularly high flexibility and is J-shaped when not restrained, and is easily introduced into the blood vessel. In FIG. 4, in order to easily understand the J-shape when the distal end portion 20 a of the guide wire 20 is not restrained, the tube 26 is fed out in the state of a single piece of the guide wire introducing tool 12 and the guide wire 20 is Further, the state where the J-shaped portion of the distal end portion 20a protrudes from the tube 26 is shown. The J-shaped guide wire 20 is prepared with various degrees and magnitudes of bending (curving) according to the type of procedure and the operator's request. The guide wire 20 is provided with a scale symbol (not shown) indicating the length from the tip.

  Returning to FIG. 2 and FIG. 3, the first pipe 22 has a shape wound by one or more turns, and only one opening 22 a is opened, and the other is closed. In the initial state, the rear end of the guide wire 20 reaches the vicinity of the other end of the first pipe 22, and the other end is closed, so that the insertion amount of the guide wire 20 is set appropriately. The first pipe 22 has a certain degree of elasticity.

  The vicinity of the rear end of the first pipe 22 is fixed to the adjacent winding part by the fastener 30, and the opening 22 a is the substantially end part of the arc-shaped fixing tool 32 to the adjacent winding part. It is fixed. The fastener 30 and the fixture 32 frictionally fix the first pipe 22 so as to be slidable.

  A support bar 34 extends from the fixture 32 in the opening direction of the opening 22a, and the second pipe 24 is connected to the support bar 34. A protrusion 36 that supports the guide wire 20 is provided at a substantially central portion of the support bar 34. The opening direction of the opening 22a, the support bar 34, and the second pipe 24 are arranged substantially linearly. Both ends of the second pipe 24 are open.

  The tube 26 has an inner diameter slightly larger than the outer diameter of the guide wire 20 and covers the distal end portion 20 a of the guide wire 20. The tube 26 can be moved integrally with the guide wire 20 with appropriate friction. When a moderately large force is applied, the guide wire 20 can be fed out while sliding on the inner surface of the tube 26. .

  The tube 26 is flexible enough to bend when it abuts against the wall surface in the Y hub 14, and restrains the J-shaped portion at the tip of the guide wire 20 in a substantially straight line when there is no external force. It has a suitable rigidity. Since the distal end portion 20a of the guide wire 20 is highly flexible, the tube 26 does not need to be excessively rigid, and can be made of a flexible material in practice. For example, a thin nylon tube is used. Can do.

  In the initial state, the front half of the tube 26 is inserted and arranged in the second pipe 24 together with the distal end portion 20a of the guide wire 20, and does not protrude from the advancer 24a constituting the front end opening. A stopper 38 is provided at the rear end of the tube 26 so as not to be inserted into the opening 22 a of the first pipe 22 and the opening 24 b of the second pipe 24. When the guide wire introduction tool 12 is used, the stopper 38 abuts on the opening 24b of the second pipe 24 and restricts the tube 26 from being led out at an appropriate position. The rear end portion of the tube 26 and the stopper 38 are disposed above the support bar 34, between the opening 22a and the opening 24b, specifically, in the vicinity of the opening 22a.

  The advancer 24a at the tip of the second pipe 24 has a tapered shape provided with a plurality of ribs.

  As shown in FIG. 5, the Y hub 14 of the puncture device 11 has a bifurcated shape, and is connected to the straight main port 40 and an acute angle θ (for example, about 30 °) with respect to the main port 40. The side port 42 to which the advancer 24a of the second pipe 24 is attached is connected, and the hemostasis valve 44 and the port member 46 provided in the side port 42 are provided. The inner surface at the rear end of the main port 40 and the outer surface of the front end are tapered. A connection portion of the side port 42 to the main port 40 has a tapered shape so that the guide wire 20 can be guided.

  The port member 46 is fixed to the opening 42b on the inlet side of the side port 42. The inner surface of the opening has a tapered shape, and the rib of the advancer 24a is engaged and securely connected. The distal end of the port member 46 is a flange 46a, and the hemostasis valve 44 is kept fluid tight with the step surface 42a in the side port 42. Inside the port member 46, a tapered surface 46b and a narrow guide hole 46c passing through the flange 46a from the tip of the tapered surface 46b are provided, and the guide wire 20 led out from the second pipe 24 is connected to the hemostasis valve 44. Guide to the center. The central portion of the flange 46a slightly protrudes and elastically bites into the central portion of the hemostasis valve 44.

  The hemostasis valve 44 is made of, for example, silicone rubber, and the guide wire 20 can be inserted through the substantially central portion, and the side port 42 is kept fluid-tight when the guide wire 20 is not inserted.

  Specifically, as shown in FIG. 6, the hemostasis valve 44 includes a first cut 48a reaching one surface and a second cut 48b reaching the other surface. The first cut 48a and the second cut 48b are connected to each other at a substantially central portion inside the hemostasis valve 44, and are arranged so as to intersect at approximately 90 ° in plan view (plan view is omitted). Each of the first cut 48a and the second cut 48b has a substantially semicircular shape, and the arc portions are connected. Such a hemostasis valve 44 is easy to pass the guide wire 20 and has high liquid tightness.

  The Y hub 14 is basically configured in such a simple manner, and a conventional product (for example, a puncture device described in Patent Document 1) may be used.

  The syringe 16 is a general-purpose product and includes a syringe body 50, a plunger 52, and a gasket 53, and the syringe body 50 is taper-connected to the rear end portion of the main port 40.

  The puncture needle 18 is a general-purpose product and includes a needle 54 and a needle hub 56 that holds the needle 54, and the needle hub 56 is taper-connected to the front end portion of the main port 40.

  Next, the operation of the guide wire introducing tool set 10 and the guide wire introducing tool 12 configured as described above will be described.

  First, as shown in FIG. 7, the syringe 16 and the puncture needle 18 are connected to the main port 40 of the Y hub 14, the advancer 24 a is connected to the side port 42, and the Y hub 14 is gripped. Then, the puncture needle 18 is punctured into the blood vessel (for example, vein) of the patient. Instead of the puncture needle 18, an indwelling needle or the like may be used. The puncture site is covered with a perforated drape (not shown). When the puncture needle 18 is correctly punctured into the blood vessel, blood is introduced into the syringe 16 through the main port 40 of the Y hub 14, and so-called flashback occurs. At this time, the plunger 52 of the syringe 16 is appropriately pulled to promote flashback. The blood introduced into the Y hub 14 does not leak from the side port 42 due to the liquid-tight action of the hemostasis valve 44. The operator confirms that proper flashback has occurred.

  In the main port 40 of the Y hub 14, there is no obstacle that hinders flashback, and flashback can be performed in a short time. 7 shows blood by flashback, but the illustration of blood is omitted in FIGS. 8 to 11 so that the state of the guide wire 20 can be easily understood.

  Next, as shown in FIG. 8, the guide wire 20 is pushed out together with the tube 26. The guide wire 20 and the tube 26 protrude from the advancer 24a and are inserted into the side port 42. At this time, the guide wire 20 is held in a substantially linear shape because the tube 26 is covered. Therefore, although the guide wire 20 and the tube 26 are guided to some extent by the tapered surface in the port member 46, the guide wire 20 and the tube 26 extend straightly toward the center of the hemostasis valve 44 and extend straight. It penetrates 48a and the second cut 48b.

  The guide wire 20 alone has a J-shaped tip, and is difficult to be brought into direct contact with the surface of the hemostasis valve 44. Further, since the guide wire 20 is highly flexible, the first cut of the hemostasis valve 44 is difficult. It may be difficult to penetrate through 48a and the second cut 48b.

  On the other hand, in the guide wire introducing tool set 10 and the guide wire introducing tool 12, the guide wire 20 is covered with the tube 26 and held in a substantially linear shape, so that it is substantially perpendicular to the surface of the hemostasis valve 44. Further, the tube 26 can ensure a proper rigidity, and can reliably penetrate the hemostasis valve 44 while expanding the first cut 48a and the second cut 48b. Even if the guide wire 20 and the tube 26 penetrate, the hemostasis valve 44 keeps the side port 42 fluid-tight.

  When the guide wire 20 and the tube 26 are further pushed out, the tips thereof are still maintained in a substantially straight shape, proceed straight through the side port 42, and are not caught or rounded in the side port 42. Enter 40 correctly.

  As shown in FIG. 9, the guide wire 20 enters the main port 40 and contacts the inner wall surface 40a. As understood from FIG. 9, the guide wire 20 and the tube 26 abut against the inner wall surface 40a at an angle substantially equal to the acute angle θ. Therefore, when the guide wire 20 and the tube 26 are further pushed out, the tube 26 also has appropriate flexibility. Therefore, as shown in FIG. 10, the guide wire 20 and the tube 26 bend along the inner wall surface 40a. , Forward and guided to the needle hub 56.

  Since the tip of the guide wire 20 alone is J-shaped, as shown by the phantom line in FIG. 9, the guide wire 20 does not necessarily contact the inner wall surface 40a at an acute angle, and the tip portion does not contact the inner wall surface 40a. Since the guide wire 20 is not always in contact with each other and is highly flexible, there is a concern that if the guide wire 20 is pushed out as it is, the guide wire 20 may move irregularly in the Y hub 14. For example, the connection portion between the side port 42 and the main port 40 May be curled up or may proceed in the direction of the opposite syringe 16.

  On the other hand, in the guide wire introducing tool set 10 and the guide wire introducing tool 12, the guide wire 20 is covered with the tube 26 and held in a substantially straight shape, and therefore makes contact with the inner wall surface 40a at an acute angle. In addition, since the tube 26 has moderate flexibility, the tube 26 is correctly guided along the inner wall surface 40a to the needle hub 56.

  As shown in FIG. 11, when the guide wire 20 and the tube 26 are further pushed out, the stopper 38 comes into contact with the opening 24b on the inlet side of the second pipe 24 and the further entry of the tube 26 into the second pipe 24 is restricted. Is done. At this point in time, as understood from FIG. 11, the distal ends of the guide wire 20 and the tube 26 have reached the vicinity of the hollow opening of the needle 54 or the position slightly inserted into the needle 54 in the needle hub 56.

  At this time, since the tube 26 covers the guide wire 20 in the Y hub 14 over the entire length, the guide wire 20 can be correctly guided in the Y hub 14. The rear end of the tube 26 is disposed in the opening 24 b of the second pipe 24, and has a length necessary and sufficient for correctly guiding the guide wire 20 in the Y hub 14.

  The series of operations so far may be performed by gripping the position of the stopper 38. Up to this point, since the guide wire 20 operates integrally with the tube 26, the guide wire 20 is not caught on the inner wall of the tube 26. Even in the subsequent operation, the tip of the guide wire 20 comes out of the tube 26, so that the guide wire 20 is not caught on the inner wall of the tube 26.

  When the guide wire 20 is further led out while being slidably contacted with the tube 26, the leading edge of the guide wire 20 reaches the vicinity of the opening of the hollow portion of the needle 54, so that it enters the hollow portion and advances. The hollow portion of the needle 54 has a sufficiently small diameter, and the guide wire 20 moves forward while being held in a straight line, and is not caught on the way or moved in the reverse direction.

  Eventually, as shown in FIG. 12, the guide wire 20 protrudes from the distal end opening of the needle 54, is not restrained (or the degree of restraint is reduced), and returns to the J shape in the blood vessel 90. Thereafter, for example, as shown by the phantom line in FIG. 12, the guide wire 20 is led to a predetermined position in the blood vessel 90 with the J-shaped bent portion at the head. Since the distal end of the guide wire 20 is bent into a J shape when not restrained, the guide wire 20 can be smoothly inserted into the blood vessel.

  Further, the puncture needle 18, the Y hub 14, and the guide wire introduction tool 12 are pulled out from the rear end portion of the guide wire 20 while leaving the guide wire 20. As a result, a predetermined amount of the guide wire 20 is inserted into the blood vessel 90, and the remaining portion is set in a state where it protrudes from the puncture site.

  Next, as shown in FIG. 13, a hollow dilator 60 is inserted through the guide wire 20, and the puncture site and the blood vessel are appropriately expanded. When the dilator 60 is inserted, the insertion port may be appropriately cut out with a knife. Thereafter, the dilator 60 is removed.

  Next, as shown in FIG. 14, the catheter 70 is inserted through the guide wire 20 through a predetermined guide tube and inserted into the blood vessel by an appropriate length. The guide tube is provided to ensure strength when inserted into the blood vessel 90 and to protect the tube. The catheter 70 includes, for example, a first catheter 72 for supplying nutrients and a second catheter 74 for supplying medicines. The first catheter 72 and the second catheter 74 are integrated into a common catheter 76 on the way. The portion of the common catheter 76 is inserted into the blood vessel. The common catheter 76 has a two-tube structure in cross section.

  Further, after fixing the catheter 70 to the skin, the guide wire 20 and the guide tube are pulled out. The first catheter 72 and the second catheter 74 are closed with a clamp (not shown) when not in use.

  As described above, according to the guide wire introduction tool set 10 and the guide wire introduction tool 12 according to the present embodiment, the guide wire 20 passes through the hemostasis valve 44 because the guide wire 20 is restrained in a substantially linear shape by the tube 26. In addition, it is guided correctly from the side port 42 to the front end opening of the main port 40. The Y hub 14 to be applied has a simple configuration similar to that of the conventional product. The Y hub 14 does not require an inner tube as in Patent Document 2 and is easy to assemble. There is also a situation in which blood enters the gap between the inner tube and the main body and the blood coagulates. I don't get it.

  Of course, the guide wire introducing tool and the guide wire introducing tool set according to the present invention are not limited to the above-described embodiments, and various configurations can be adopted without departing from the gist of the present invention.
