Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a porous Y-shaped connector capable of fixing a guide wire and reducing the winding of the guide wire. Background Art

[0002] Percutaneous coronary intervention has become an important means of treating coronary heart disease. Selecting a suitable guidewire to pass through the lesion to the distal end of the target vessel is the cornerstone of successful percutaneous coronary intervention. When encountering complex lesions, such as bifurcation lesions, chronic occlusive lesions, and difficulty in delivering the balloon due to vascular torsion, multiple double guidewires or even multiple guidewire technology must be used to complete the treatment of main branch and branch lesions, protect bifurcation lesions, and strengthen the support of the guide catheter. However, with the increase in the number of guidewires, on the one hand, the probability of guidewire entanglement gradually increases, and on the other hand, because the tail ends of most guidewires have similar morphology, guidewire confusion is prone to occur.

[0003] Once the guidewire is entangled, the balloon and stent cannot be advanced, and when the guidewire is withdrawn, all guidewires are easily withdrawn, which will bring great difficulties to the interventional treatment. The reasons for the guidewire entanglement are, on the one hand, the excessive rotation of the subsequent guidewire causing the winding action, and on the other hand, the repeated crossing of the guidewire outside the body. At present, the Y-type connector commonly used in clinical practice has only a single outlet, and all guidewire instruments used in interventional treatments enter and exit through this outlet. When multiple guidewires are required for operation, it is easy for the guidewires to cross repeatedly at the opening, and it is impossible to simply and clearly identify the guidewires located in different blood vessels. Utility Model Content

[0004] The utility model provides a porous Y-shaped connector capable of fixing a guide wire and reducing the entanglement of the guide wire. The Y-shaped connector is composed of a main pipe and a bypass pipe connected in a Y shape. A pressing cap is connected to one end of the main pipe. The outer end cover of the pressing cap is provided with a plurality of guide wire through holes along the circumferential direction. The outer end cover of the pressing cap is provided with a plurality of different marks corresponding to each of the guide wire through holes. A plurality of guide wire fixing devices corresponding to the positions of the guide wire through holes are installed on the outer edge of the pressing cap.

[0005] The guide wire fixing device is composed of an elastic band and a rubber fixing clip. One end of the elastic band is fixed to the outer edge of the pressing cap, and the other end is fixedly connected to the rubber fixing clip.

[0006] Furthermore, the pressing cap is provided with three guide wire through holes, and the connecting lines of the three guide wire through holes form an equilateral triangle, and three guide wire fixing devices are installed on the outer edge of the pressing cap.

[0007] Furthermore, three protrusions are provided on the outer edge of the pressing cap, a clamping hole is provided on the top of the protrusion, and one end of the elastic band is interference-connected with the clamping hole.

[0008] Furthermore, the elastic band is a rubber band, one end of the elastic band is provided with a rubber ball embedded in the clamping hole, and the diameter of the rubber ball is larger than the inner diameter of the clamping hole.

[0009] This Y-type connector is improved on the basis of the traditional Y-type connector. Multiple guidewire entry routes are added to the pressing cap, and a simple guidewire fixing clip made of a rubber damping block connected with an elastic, length-adjustable telescopic rope is added next to the entry route. When not in use, the rubber fixing clip can be completely retracted to the side of the pressing cap. The operation method is similar to that of the traditional Y-type connector. When the side branch guidewire is in place, the rubber fixing clip can be used to fix the side branch guidewire to prevent the side branch guidewire from shifting during the operation of the main branch guidewire. At the same time, due to the different entry routes of multiple guidewires, even if the guidewires look similar during the operation, they can be easily distinguished outside the body, and the guidewire entanglement caused by repeated crossing of the guidewires outside the body is completely avoided, which provides convenience for interventional treatment of complex lesions.

[0015] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0016] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0017] Reference Figure 1-3 As shown, the utility model provides a porous Y-shaped connector for fixing a guidewire to reduce the entanglement of the guidewire. The Y-shaped connector is composed of a main pipe 1 and a bypass pipe 2 connected in a Y shape. A pressing cap 3 is connected to one end of the main pipe 1. The outer end cover of the pressing cap 3 is provided with a plurality of guidewire through holes 4 along the circumferential direction. The pressing cap 3 is provided with a mark 6 (i.e., a mark corresponding to each guidewire through hole 4) Figure 2 and Figure 3 1, 2, 3 in larger font), a plurality of guide wire fixing devices 5 corresponding to the positions of the guide wire perforations 4 are installed on the outer edge of the pressing cap 3. The guide wire fixing device 5 is composed of an elastic band 51 and a rubber fixing clip 52, one end of the elastic band 51 is fixed to the outer edge of the pressing cap 3, and the other end is fixedly connected to the rubber fixing clip 52.

[0018] In a preferred embodiment, the pressing cap 3 is provided with three guide wire through holes 4 , and the line connecting the three guide wire through holes 4 forms an equilateral triangle. Accordingly, three guide wire fixing devices 5 are installed on the outer edge of the pressing cap 3 .

[0019] In an optional embodiment, three protrusions 31 are provided on the outer edge of the pressing cap 3, and a clamping hole 32 is provided on the top of the protrusion 31. One end of the elastic band 51 is interference-connected with the clamping hole 32. The elastic band 51 is a rubber band, and one end of the elastic band 51 is provided with a rubber ball 53 embedded in the clamping hole 32. The diameter of the rubber ball 53 is larger than the inner diameter of the clamping hole 32. By inserting the rubber ball 53 into the clamping hole 32, the elastic band 51 is fixedly connected to the pressing cap 3. Figure 4 shown.

[0020] In complex coronary intervention, multiple different guide wires must be used to be delivered to different target blood vessels. This Y-type connector is used instead of the traditional Y-type connector. After the guiding catheter is delivered to the coronary artery opening, the guide wire is assisted by the inserter to enter the pressing cap and then enter the guiding catheter through the Y-type connector to the coronary artery opening, and then delivered to the target blood vessel as needed, and then the inserter is withdrawn. According to the needs of lesion treatment, the above operation can be repeated, and different guide wires can be simply and conveniently delivered to the target blood vessel through different guide wire perforations 4. When the guide wire is in place, the elastic and length-adjustable rubber fixing clip 52 beside the corresponding entrance can be pulled out to fix the guide wire relatively to the outside of the Y-type connector pressing valve to avoid the displacement of the side branch guide wire during the operation of the main branch guide wire. At the same time, in vitro, according to different entrances, different labels 6 are set next to each entrance, and the three different guide wires can be easily distinguished, and the guide wire will not be entangled in vitro.

[0021] The Y-type connector is provided with three guidewire holes 4 on the pressing cap to accommodate three different guidewires entering and exiting the connector and then entering the guiding catheter. Next to each guidewire hole 4, a corresponding guidewire fixing device 5 is provided. When in use, it is similar to the traditional Y-type connector. The guidewire is assisted by the inserter to enter the entrance at the pressing cap, and then enters the guiding catheter through the Y-type connector to be sent to the diseased blood vessel. After one guidewire is in place, the inserter is withdrawn, and the remaining guidewires are sent in the same way. Eventually, three different guidewires can be sent to the target lesion. When the guidewire is in place, the guidewire can be relatively fixed to the outside of the pressing valve of the Y-type connector (such as Figure 3 As shown in FIG. 1 ). Since the three guide wires enter the catheter through different entrances, they can be easily distinguished outside the Y-type connector and will not be entangled due to repeated crossing of the guide wires outside. At the same time, since the side branch guide wires are fixed by the guide wire fixing device 5, the side branch guide wires can be prevented from shifting when the main branch guide wire is operated.

[0022] The advantages of the utility model are:

[0023] 1. Solved the problem of easy entanglement during multi-guidewire operation: By designing a multi-entry press cap and guidewire fixing device, each guidewire can be independent, reducing the crossing and entanglement between guidewires, and improving the efficiency and safety of the operation.

[0024] 2. Improved the convenience of guidewire identification: Each guidewire perforation has a corresponding mark, allowing doctors to easily distinguish different guidewires during the operation and avoid the problem of guidewire confusion.

[0025] 3. Improved stability of guide wire fixation: Through the combination of elastic band and rubber fixing clip, the guide wire can be firmly fixed to prevent the guide wire from shifting during the operation, ensuring the smooth progress of the operation.

[0026] 4. Simplified surgical operation: The design of the utility model makes the surgical operation easier, allowing doctors to focus more on the treatment of lesions, thereby improving the success rate of the operation.

[0027] 5. Wide scope of application: The utility model is applicable to various percutaneous interventional treatments of coronary arteries, especially for complex lesions requiring multi-guidewire operations, and has significant advantages and application value.
