DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a guide wire insertion jig (slider) and an insertion aid.

[0002]

2. Description of the Related Art FIGS. 15 and 16 are schematic views of a conventional guide wire insertion aid. An auxiliary tool 61 shown in FIG. 15 is a guide wire insertion jig 64 attached to a distal end of a sheath 63 accommodating a guide wire 62.
Is attached. The auxiliary tool 61 separates the insertion jig 64 from the sheath 63 with one hand when inserting the guide wire 62 into a catheter or an indwelling needle hub inserted into a patient's blood vessel, and exposes the guide wire 62 with the other hand.
Must be sent in the direction of the hub, and the operation is troublesome. The auxiliary tool 71 in FIG.
As described in No. 52, the guide wire insertion jig 74 is designed to be easily operated with one hand.
The guide wire 72 is fed toward the hub with the thumb of one hand from above. However, since the auxiliary tool 71 fixes the wound sheath 73 by providing the sheath holding portion 76 on the bottom surface of the insertion jig 74 via the arm portion 75, the insertion jig 74 and the guide wire 72 to the hub or the like are fixed. Since the insertion angle was limited, the insertion work was difficult. Also, as shown in FIGS. 17 and 18 (enlarged view of the portion A in FIG. 17), a projection 78 and a rubber ring 79 are provided behind the guide wire support 77, and the guide wire 72 is provided.
, The guidewire could not be inserted deeply into the hub or the like, making it difficult to feed the guidewire. Further, the number of parts is large, the shape is complicated, and the cost is high. The inventors of the present invention have conducted intensive studies in order to solve the above problems, and as a result, have arrived at the next invention.

FIG. 1 is a schematic view of a guide wire insertion aid 1 (hereinafter referred to as "aid 1") of the present invention, and FIG. 2 is a guide wire insertion jig (FIG. 1) constituting the aid 1 of FIG. 3 is a side view of FIG. 2, FIG. 4 is a sectional view taken along line AA of FIG. 2, FIG. 5 is a right side view of FIG. 3, and FIG. 6 is a left side view of FIG. Figure). The assisting tool 1 is provided with a sheath 5 for accommodating a guide wire 7, a slider 2 in front of the sheath 5, and a terminal cap 6 for a guide wire in the rear, and a slider attached to a sheath holding portion 14 of the slider 2 and the sheath 5 adjacent thereto. It is configured by attaching the clamp 3 and attaching the sheath clamp 4 to another portion of the sheath 5.

[0005] As shown in FIGS. 2 to 6, the slider 2 has a flat slide portion 12 formed in the middle of the main body 11, and a sliding contact portion 16 is protruded from the center of the slide portion 12. On the bottom surface, a finger hook 15 depressed inward is formed. A cylindrical guide wire support 13 having a guide wire insertion passage 19 is provided in front of the main body 11. A tubular sheath holding portion 14 having a sheath mounting groove 18 and a guide wire insertion passage 20 is provided behind the main body 11. A pair of grooves 14A is formed on both sides of the sheath holding portion 14 in the length direction. Body 1
A gentle and long slope portion 17 is formed between the first slide portion 12 and the guide wire support portion 13. The slope θ of the slope 17 is 10 ° to 30 °, preferably 15 °.
From 25 ° to 25 °. The length L1 of the slope 17
Is formed at 10% to 20%, preferably 15% to 17% with respect to the entire length L2 (100%) of the main body 11.
The guide wire 7 can be easily fed by the slope portion 17. Also, the sliding portion 12 of the main body 11
A slope portion 17A is also formed between the sheath holding portion 14, and the slope portion 17A is formed to be steeper and shorter than the slope portion 17.

FIG. 7 is a plan view of the slider clamp 3 (FIG. 8 is a right side view of FIG. 7, and FIG. 9 is a left side view of FIG. 7).
The slider clamp 3 has a mounting groove 21 of the sheath holding portion 14 of the rectangular slider 2 and a mounting groove 2 of the circular sheath 5.
3 are formed, and a pair of protrusions 22 are formed in the mounting groove 21. The groove 14A of the sheath holding portion 14 of the slider 2 is mounted on the projecting portion 22, and the sheath 5 adjacent to the sheath holding portion 14 is mounted (axially attached) on the mounting groove 23, so that the fastener of the slider 2 and the sheath 5 is fixed. Used as
Further, the slider clamp 3 and the slider 2 held by the slider clamp 3 can be freely rotated around the sheath 5.

FIG. 10 is a plan view of the sheath clamp 4 (FIG. 1).
1 is a right side view of FIG. 10, and FIG. 12 is a left side view of FIG. The sheath clamp 4 is formed with a pair of circular sheath-shaped mounting grooves 25 for the sheath 5. When the sheath 5 is wound, it is mounted on the mutually adjacent sheaths 5 and used as a fastener for the sheath 5. FIG. 13 is a partially cutaway view of the terminal cap 6 and FIG.
4 is a right side view of FIG. Terminal cap 6
Is provided to prevent the guide wire 7 from dropping from behind the sheath 5. Further, since the terminal cap 6 can be fitted with the tip of a syringe or the like,
Used when injecting a washing solution such as physiological saline.

Next, an example of a method of using the guide wire insertion aid 1 of the present invention will be described. The guide wire 7 is sent backward by the thumb while holding the sheath 5 and the slider 2 with one hand, and the tip of the guide wire 7 is straightened in the guide wire insertion passage 19 of the guide wire support portion 13 and then punctured by the patient. The guide wire support portion 13 of the slider 2 is inserted into a hub of an indwelling needle or a catheter, and the guide wire 7 can be inserted into a patient via a hub or the like while sending the guide wire 7 forward with a thumb.

[0009]

Since the slider 2 can be freely rotated about the sheath 5 on which the slider clamp 3 is mounted, the insertion angle of the sheath 5 and the guide wire 7 is set to an easy-to-insert angle so that a hub or the like can be inserted. Can be inserted. Further, since the slope 17 of the slider 2 has a gentle and long slope, the moving pitch of the guide wire 7 can be increased, and even if the guide wire support 13 is inserted deeply into a hub or the like, the guide wire can be moved. 7 is easy to send, so the operability is very good.
