[0030] Reference Figure 1-Figure 3 In this embodiment, a visualized Eustachian tube balloon dilatation catheter is disclosed, comprising: a guide component 1, a catheter component 2, a visualization component 3 and a control component 4, wherein the guide component 1 has a guide line 101 and a visualization line 102, the guide line 101 is adjacent to the visualization line 102, and the guide line 101 has a bending portion 103 extending from the first end of the guide component 1. It can be understood that the guide line 101 and the visualization line 102 are adjacent, that is, the two can be in a connected state or in a disconnected state;

[0031] The catheter component 2 is located in the guide channel 101 of the guide component 1 and can move along the guide channel 101 to enter or move out of the lesion position. Therefore, it can be known that the catheter component 2 can also produce a certain deformation, that is, it can also bend under the force of the guide channel 101;

[0032] The visualization component 3 is located in the visualization pipeline 102 of the guide component 1. Specifically, the visualization component 3 integrates a light source system and an image acquisition system to simultaneously perform lighting and image acquisition. The visualization component 3 can be implemented using a micro camera structure in the prior art. It only needs to be fixed in the visualization pipeline 102. The specific structure is not described in detail in this embodiment. At the same time, the various lines based on the visualization component 3 can also be organized in the visualization pipeline 102.

[0033] The control component 4 is connected to the second end of the catheter component 2. The control component 4 has a first extension pipeline 401 and a second extension pipeline 402 that are respectively adapted to be connected with the guide pipeline 101 and the visualization pipeline 102. It can be known that each line of the above-mentioned visualization component 3 can be connected with an external device in sequence through the visualization pipeline 102 and the second extension pipeline 402 to realize information transmission, such as the transmission of images of the lesion location.

[0034] The visualized Eustachian tube balloon dilatation catheter in this embodiment integrates the visualization component 3 and the catheter component 2 into the above-mentioned guide component 1, so that the position of the catheter component 2 can be observed in real time through the visualization component 3 during surgery, which facilitates its entry into the lesion location and simplifies the operation steps.

[0035] Preferably, the guide pipeline 101 and the visualization pipeline 102 are arranged in parallel, and there is a predetermined distance between the two. That is, it can be understood that under the premise that the guide pipeline 101 and the visualization pipeline 102 can be in a connected state or in a disconnected state, in this embodiment, it is preferred that they are in a disconnected state. Since the visualization component 3 is applied to the visualization pipeline 102, its various lines are complicated, so when the guide pipeline 101 and the visualization pipeline 102 are in a connected state, it also interferes with the movement of the catheter component 2. Accordingly, setting the guide pipeline 101 and the visualization pipeline 102 in a disconnected state can avoid the above interference, thereby facilitating the movement of the catheter component 2.

[0036] Specifically, in this embodiment, the bending direction of the bending portion 103 is toward the visualization component 3. It can be understood that the bending direction of the bending portion 103 is toward the visualization component 3, so that the bending portion 103 is located in the image acquisition area of ​​the visualization component 3, so as to facilitate the image acquisition work of the visualization component 3. Furthermore, the end of the guide pipeline 101 close to the bending portion 103 can be inclined to expand the image acquisition area of ​​the visualization component 3.

[0037] Specifically, in this embodiment, the bending portion 103 is made of a flexible material, that is, the bending portion 103 can be set to any inclination angle at will, so as to adapt to different working environments and facilitate access to the lesion location.

[0038] Specifically, in this embodiment, the catheter component 2 includes a catheter 201, a balloon 202 and a valve 203, wherein the balloon 202 is arranged at the first end of the catheter 201, and the valve 203 is arranged at the second end of the catheter 201. More specifically, the first end of the catheter 201 is in the same direction as the first end of the guide component 1, so that the balloon 202 can enter the lesion position (in this embodiment, the Eustachian tube) through the guide component 1 to dilate the Eustachian tube. The catheter 201 includes an inner tube and an outer tube, and a dilation pipeline connecting the balloon 202 and the valve 203 is formed between the inner tube and the outer tube, that is, after the valve 203 is docked with an external gas device, gas can be continuously and slowly input to expand the balloon 202, thereby dilating the Eustachian tube. The catheter component 2 (i.e., the balloon dilation catheter) can directly perform cavity flushing after balloon dilation, thereby avoiding the technical problem that the existing balloon dilation catheter needs to be removed and replaced after dilation.

[0039] Preferably, the valve 203 is a Y-shaped valve, which has less resistance and is convenient for draining. Preferably, the catheter component is compatible with a 0.014" guide wire.

[0040] Specifically, in this embodiment, the conduit component 2 further includes a slider 204, which is connected to the conduit 201 so as to drive the conduit 201 to move, and the guide component 1 and / or the control component 4 are provided with a slide groove (not shown in the figure) adapted to the slider 204. Preferably, in this embodiment, since the movable area of ​​the conduit component 2 is usually relatively limited, in this embodiment, only a slide groove is provided on the control component 4 for the slider 204 to slide. By providing the slider 204, it is convenient for manual operation to move the conduit 201.

[0041] Specifically, in this embodiment, the control component 4 includes a control handle 403, and a gripping groove (not shown in the figure) is provided on the outer side of the control handle 403. By providing the gripping groove, it is convenient to apply gripping force during manual operation, thereby improving stability during surgery.

[0042] Specifically, in this embodiment, the guide component 1 and / or the control component 4 are formed by assembling two symmetrical substructures. That is, it can be understood that the above-mentioned guide component 1 and control component 4 are symmetrical structures, which is convenient for processing and mass production, and the two substructures can be assembled by snapping.

[0043] When the visualized Eustachian tube balloon dilatation catheter in this embodiment is used, the first end of the guide component 1 is first inserted into the vicinity of the target position through the cooperation of the visualization component 3. After the visualization component 3 confirms that the guide component 1 has reached the predetermined position, the catheter 201 is slowly pushed by the slider 204 until the balloon 202 reaches the lesion position. After the visualization component 3 confirms that the position is correct, it is docked with an external device to inflate the balloon 202 to dilate the Eustachian tube. After the desired result is obtained, the balloon 202 is restored to the rolled state.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
