DETAILED DESCRIPTION

[0023] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0024] For example, Figures 1-5As shown, a single bilateral switching bronchial occluder includes a main pipe body 1 which is inserted into the corresponding tracheal tube as a whole, and no re-intubation is required for postoperative ventilation. The main pipe body 1 is internally provided with a breathing pipe 2 which is connected with a receiving pipe 3 at the end of the main pipe body 1, allowing oxygen delivery to the isolated lung during the operation. The receiving pipe 3 is fixed with an occlusion air bag 4, and the main pipe body 1 is internally provided with an inflation pipe 5 in communication with the occlusion air bag 4, and the other end of the inflation pipe 5 is connected with a proximal air bag 6 corresponding to the occlusion air bag 4. Pressing the proximal air bag 6 makes the corresponding occlusion air bag 4 expand to achieve occlusion. The receiving pipe 3 and the occlusion air bag 4 are connected with an extension pipe 7, and the extension pipe 7 is provided with a telescopic assembly 8. The extension pipe 7 and the occlusion air bag 4 can be received into the receiving pipe 3. The telescopic assembly 8 is used to adjust the position of the occlusion air bag 4 to ensure that it accurately falls into the bronchus for occlusion, and flexible switching between unilateral and bilateral bronchial occlusion is realized.

[0025] Specifically, similar to the conventional external telescopic structure, the telescopic assembly 8 in the embodiment also includes a corrugated section 81 provided on the extension pipe 7, except that an adjusting assembly is provided between the corrugated section 81 and the receiving pipe 3. The position of the receiving pipe 3 is fixed, and the adjusting assembly provides support and adjusts the length of the corrugated section 81. The occluder as a whole can be made of flexible material, or the extension pipe 7 is partially coated with a flexible protective coating to improve the protection of the tracheal wall, such as polyurea urethane, polyaluminum ethylene, etc.

[0026] Further, the adjusting assembly includes adjusting ring sleeves 82 which are nested one by one inside the corrugated section 81. The inside of the adjusting ring sleeve 82 is provided with an adjusting groove 83 which surrounds the circumference, and the end of the adjacent adjusting ring sleeve 82 is provided with an adjusting head 84 which is slidingly installed in the adjusting groove 83. The adjusting head 84 and the adjusting groove 83 are provided with a positioning groove 85 and a positioning protrusion 86 which are engaged with each other. The adjusting ring sleeves 82 can slide and telescope with each other, and the whole is made of elastic material. When the positioning groove 85 and the positioning protrusion 86 are engaged, the adjusting ring sleeves 82 remain in the contracted or expanded state, without affecting the normal ventilation of the internal breathing pipe 2. In addition, a conventional corrugated pipe can also be used as a substitute; the extension pipe 7 is connected with a push-pull pipe 9 between the adjusting ring sleeve 82 and the corrugated section 81. The push-pull pipe 9 is slidingly installed between the main pipe body 1 and the breathing pipe 2, and the corrugated section 81 telescopes with the push-pull pipe 9.

[0027] Further, in order to realize external gas switching, the breathing pipe 2 is provided with a gas interface 21 at the end, and the gas interface 21 is internally provided with a carbon dioxide sensor. The built-in carbon dioxide sensor judges whether the occlusion air bag 4 is completely occluded by monitoring carbon dioxide and flow.

[0028] Furthermore, the outer side of the main tube 1 is equipped with an indicator scale and a radiation identification mark. When the main tube 1 is inserted into the trachea, the indicator scale and radiation identification mark simultaneously determine the insertion depth and provide visual guidance for subsequent operations.

[0029] In addition, unlike conventional pipe structures, the main pipe 1 in this embodiment is fitted with a limiting sleeve 11 on the outside, and the limiting sleeve 11 has a built-in locking component. The limiting sleeve 11 is connected to the outer pipe, further expanding the applicability of the plug.

[0030] Meanwhile, the limiting sleeve 11 is provided with a limiting port 12 that is inclined outward, and the limiting port 12 and the end of the limiting sleeve 11 are respectively provided with threaded ports 13. The threaded ports 13 facilitate the connection of external sleeves, thereby further extending the main body 1.

[0031] As can be seen, unlike conventional locking structures, the locking assembly in this embodiment includes a locking ring 14 rotatably mounted on the limiting sleeve 11. The locking ring 14 and the limiting sleeve 11 are provided with mutually meshing limiting teeth 15. A limiting block 16, opposite to the main body 1, is movably mounted inside the limiting sleeve 11. A guide slope 17 is provided between the limiting block 16 and the locking ring 14. Rotating the locking ring 14 causes the guide slope 17 inside the limiting sleeve 11 to apply a pushing force to the limiting block 16, thereby pressing the limiting sleeve 11 against the main body 1 to achieve axial orientation restriction.

[0032] Clearly, corresponding indicator marks are provided on the outer sides of the proximal airbag 6 and the occlusion airbag 4. These indicator marks provide operational guidance for the proximal airbag 6 and the occlusion airbag 4, preventing confusion during use.

[0033] Preferably, the receiving tube 3 has an observation port 31 facing one side, which is typically used for placing an optical fiber or video bronchoscope, or for introducing a suction catheter.

[0034] Example 1

[0035] like Figure 1 As shown, the bronchial occluder in this embodiment is suitable for occluding both bronchi. The two extension tubes 7 and the occlusion airbags 4 extend from the receiving tube 3. When in use, the two extension tubes 7 and the occlusion airbags 4 are inserted into the bronchi respectively. The proximal airbag 6 is manually pressed to make one of the occlusion airbags 4 expand to block a single bronchus, or both occlusion airbags 4 expand to completely block the bronchi.

[0036] Example 2

[0037] like Figure 2As shown, the bronchus blocking device in the embodiment is suitable for blocking unilateral bronchus, wherein one extension tube 7 and its blocking balloon 4 are accommodated in the accommodating tube 3, and the other extension tube 7 and its blocking balloon 4 are extended from the accommodating tube 3, and in use, the extension tube 7 and its blocking balloon 4 are inserted into the unilateral bronchus, and the proximal balloon 6 is manually pressed to make the blocking balloon 4 expand to achieve the blocking of unilateral bronchus; when it is needed to switch the blocking position, the main tube body 1 is pulled out and inserted again in the direction to make the extension tube 7 and its blocking balloon 4 inserted into the bilateral bronchus.

[0038] Embodiment three

[0039] In the embodiment, the main tube body 1 is inserted into the trachea, and the push-pull tube 9 is pushed or pulled manually to make the extension tube 7 extended from or retracted into the accommodating tube 3, so that the unilateral and bilateral bronchus blocking switching can be realized during the operation, and the accommodating tube 3 and the breathing tube 2 form a cannula structure, which does not affect the normal in and out of the breathing tube 2.

[0040] In summary, the principle of the embodiment is that the accommodating tube 3 at the end of the main tube body 1 realizes the unilateral and bilateral switching of the breathing tube 2, and the relative position of the blocking balloon 4 and the accommodating tube 3 is adjusted by the extension tube 7 and the telescopic assembly 8 to ensure the accurate positioning of the blocking balloon 4 and the sealing effect of the whole.
