In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
In the description of the present application, it should be noted that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the products of the application usually place when using, and are only used for convenience in describing the present application and simplifying the description, but do not indicate or imply that the devices or elements that are referred to must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
In the description of the present application, it should also be noted that, unless expressly stated or limited otherwise, the terms "disposed" and "connected" are to be construed broadly, and may for example be fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The guide wire auxiliary connecting device and the use method in the application are mainly used for assisting the guide wire 2 to penetrate through the balloon 3 catheter 4, and particularly used for enabling the tail end 12 of the guide wire 2 to extend into the balloon 3 from the catheter port 41 at the far end and enabling the guide wire 2 to penetrate through the whole balloon 3 in the catheter 4 and then penetrate out from the guide wire hole 6 in the catheter 4 at the near end and the outer side, so that the guide wire 2 is penetrated and guided.
The threading of the guide wire 2 in the balloon 3 catheter 4 is different from the forward threading of the traditional mode, but adopts a form similar to a needle threading form, takes the protective steel needle 1 as a needle threading form, and takes the guide wire 2 as a lead threading form, so that the protective steel needle 1 drives the guide wire 2 to penetrate through the whole balloon 3 catheter 4 and penetrate out of the guide wire hole 6.
Most of the prior art methods are that the tail end 12 of the guide wire 2 is inserted from far to near in the forward direction at the opening position of the catheter 4 at the far end of the balloon 3, so that the tail end 12 of the guide wire 2 penetrates out of the guide wire hole 6 from the catheter 4 at the outer side of the near end of the balloon 3, and the threading is completed.
However, there are practical drawbacks in the actual operation, on one hand, since the balloon 3 is coated with the drug, the balloon 3 cannot be touched directly, and only the catheter 4 at the proximal end side of the balloon 3 can be held by hand, since the structure itself is thin, the catheter 4 is easy to shake when the catheter 4 at the proximal end of the balloon 3 is held by one hand, it is difficult to make the tail end 12 of the guide wire 2 opposite to the catheter port 41 at the distal end of the balloon 3, and the operation difficulty is increased; on the other hand, even if the tail end 12 of the guide wire 2 extends into the catheter port 41, the inner wall of the catheter 4 is easily scratched in the process of extending into the catheter 4, so that the structure of the catheter 4 of the balloon 3 is damaged.
The invention changes the traditional insertion form of the guide wire 2 in the catheter 4, converts the original active insertion into the form of passive traction of the guide wire 2 by reversely inserting and pulling the protective steel needle 1 in the catheter 4, and effectively improves the penetration efficiency of the guide wire 2 in the catheter 4 of the balloon 3.
Referring to the matching relationship between the protection steel needle 1 and the balloon 3 in normal use in fig. 1, in order to prevent the balloon 3 catheter 4 with strong flexibility but low brittleness from being broken due to bending in the transportation process, the protection steel needle 1 is inserted into the balloon 3 catheter 4 from the catheter port 41 at the far end of the balloon 3, so as to effectively support the balloon 3 catheter 4 and reliably protect the structure of the balloon 3 body.
The protective steel needle 1 is inserted from a catheter port 41 at the far end of the balloon 3 and penetrates out from a guide wire hole 6 on a catheter 4 at the near end of the balloon 3 shown in fig. 2, so that the structure of the catheter 4 of the integral balloon 3 is protected.
According to the invention, the protection steel needle 1 is inserted into the catheter 4 of the balloon 3 fully, the protection steel needle 1 is inserted into the catheter port 41 at the far end of the balloon 3 from the wire guide hole 6 on the catheter 4 at the near end and the outer side of the balloon 3 in the reverse direction, a part of the guide wire 2 is hooked at the extending part of the protection steel needle 1 on the catheter port 41 at the far end of the balloon 3, then the protection steel needle 1 is pulled out of the catheter 4, the guide wire 2 passes through the catheter 4 of the balloon 3 from the catheter port 41 in a needle threading mode and penetrates out from the wire guide hole 6 on the catheter 4, and the passive traction of the guide wire 2 in the catheter 4 of the balloon 3 is realized.
The protection steel needle 1 penetrates from the thread guide hole 6, and according to the existing manufacturing process, the thread guide hole 6 is an oblique notch, and a groove is formed in the outer tube 7 in the proximal direction of the thread guide hole 6, so that the protection steel needle 1 can be conveniently inserted once, and the passing performance of the protection steel needle 1 in the thread guide hole 6 is enhanced.
Meanwhile, compared with the catheter port 41 at the far end of the balloon, the groove at the position of the yarn guide hole 6 has a relatively sufficient passing space, so that the head end 11 of the protection steel needle 1 can be prevented from scratching the inner tube when extending into the yarn guide hole 6, and the reverse insertion of the protection steel needle 1 can be rapidly completed.
Referring to fig. 6-7 in combination with fig. 3-5, the guide wire auxiliary connection device of the present invention has a main structure including a protection steel needle 1 and a guide wire 2, wherein the protection steel needle 1 is inserted into the catheter 4 and protrudes from the distal end of the balloon 3 based on the reverse insertion of the protection steel needle 1 as described above. In order to realize traction on the guide wire 2, the tail end 12 of the guide wire 2 is connected with a guide wire threading wire 5, the guide wire threading wire 5 is connected to the extending part of the protection steel needle 1, the guide wire threading wire 5 drives the guide wire 2 to enter the catheter 4 from a catheter port 41 at the far end of the balloon 3 in combination with the reverse extraction of the protection steel needle 1 from the catheter 4, and the guide wire 2 is connected to penetrate through the whole balloon 3 and extend out of the catheter 4 along with the extraction of the protection steel needle 1 from the catheter 4. Meanwhile, the protection steel needle 1 is provided with a groove 14 for hooking the guide wire threading wire 5 at the extending part of the balloon 3, so that the guide wire threading wire 5 can be conveniently fixed in the groove 14 in a hooking mode, and the reliability of passive connection and threading of the guide wire 2 is ensured.
Referring to fig. 4-5 in conjunction with fig. 2, in one embodiment, the protective steel needle 1 includes a head end 11 and a tail end 12, a guide wire hole 6 is disposed on the catheter 4 located outside the proximal end of the balloon 3, and the head end 11 of the protective steel needle 1 is inserted into the catheter 4 through the guide wire hole 6. Based on the above-described reverse insertion of the protective steel needle 1 compared to normal use, the tip end 11 of the protective steel needle 1 is inserted from the guide wire hole 6 and extends forward into the catheter 4 toward the distal end of the balloon 3 and out of the catheter port 41 at the distal end of the balloon 3.
In order to facilitate the guide wire threading wire 5 to be hooked at the extending part of the protection steel needle 1, the groove 14 is arranged at the part close to the head end 11 of the protection steel needle 1, the groove 14 extending out of the head end 11 of the protection steel needle 1 specifically forms a structure similar to a fishhook, and can accommodate the bending hooking of the guide wire threading wire 5. In particular, groove 14 comprises an oblique cutting slot 15 extending obliquely downwards towards head end 11 of protective steel needle 1, and a slot cavity 16 extending at least partially towards head end 11. Preferably, the included angle between the chamfer 15 and the vertical direction is 45 °, so that the guide wire threading wire 5 can be prevented from being loosened at the position of the groove 14. Further, the groove cavity 16 extends forwards and horizontally towards the head end 11 of the protection steel needle 1 on the body of the protection steel needle 1, so that an effective accommodating space for the guide wire threading wire 5 is formed.
