[0002] Endobronchial intubation is a commonly used lung isolation technique used to achieve single-lung ventilation during endobronchial intubation surgery. Existing endobronchial intubation tubes primarily consist of an occluding tube, a cuff, and an inflation valve. The cuff is fixed to the front end of the occluding tube and, after inflation, is used to achieve positioning and occlusion within the target bronchus. The inflation valve is located on the occluding tube and is used to inflate and deflate the cuff.

[0003] The cuff used to seal endobronchial tubes in the prior art has a poor reset effect during use. Furthermore, due to the pressure, the cuff easily wrinkles on its surface after deflation, blocking the bronchial opening, affecting the emptying of gas in one lung, causing poor lung collapse and hindering surgical operation.

[0004] Utility model patent CN202323176784.7 discloses a bronchial tube for blocking. By pulling the airbag with a pull rope, the airbag is actually fitted to the blocking tube. However, the airbag may be folded, and the airbag still cannot be completely fitted. Further, a blocking ring and a movable ring are provided. The movable ring is movably sleeved on the blocking tube. The airbag is fitted to the blocking tube by pulling the movable ring. However, this setting may result in the problem of insufficient airtightness of the airbag, affecting its use. Utility Model Content

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] like Figure 1 As shown, a disposable bronchial obturator comprises an obturator tube body 1, a conversion joint 2, a pre-inflated airbag 4 and a Y-shaped connecting tube 5, wherein a cuff 3 is provided on the outer wall of one end of the obturator tube body 1 away from the pre-inflated airbag 4, and the pre-inflated airbag 4 inflates the cuff 3 through the obturator tube body 1, and the obturator tube body 1 in the cuff 3 comprises a fixed end 101 and a movable end 102, wherein the fixed end 101 and the movable end 102 are elastically connected, and the movable end 102 is arranged away from the pre-inflated airbag 4, and further comprises a control member 8, wherein the control member 8 is used to control the length of the obturator tube body 1 in the cuff 3, and the control member 8 comprises a pull rope 802, and the pull rope 802 is arranged in the obturator tube body 1.

[0023] It should be noted that the elastic setting of the occluder tube body 1 in the cuff 3 means that the length of the occluder tube body 1 in the cuff 3 can be extended and retracted. In actual use, a telescopic rod, a bellows or an elastic material can be used to enable the telescopic operation. The pull rope 802 can pull the movable end 102 to move closer to the end of the pre-inflated airbag 4. It should be noted that in this setting, a through hole should be provided so that the gas in the occluder tube body 1 can smoothly enter the cuff 3.

[0024] Before inserting the occluder into the patient, the occluder tube body 1 in the cuff 3 is in an extended state, so that the cuff 3 is stretched and fits closely to the occluder tube body 1, thereby facilitating its insertion into the patient's bronchus. After being inserted into the appropriate position, the pull rope 802 is used to pull the movable end 102, so that the occluder tube body 1 in the cuff 3 is in a contracted state. At this time, the cuff 3 becomes relaxed, and the pre-inflated airbag 4 can be used to inflate the cuff 3, thereby achieving bronchial obstruction. When the operation is completed, the cuff 3 is first deflated, and then the pull rope 802 is loosened, so that the occluder tube body 1 in the cuff 3 returns to an extended state. The cuff 3 is stretched and fits closely to the occluder tube body 1, making it convenient to remove it from the patient's body and reducing the patient's discomfort.

[0025] In a specific embodiment, Figure 3 、 Figure 4 As shown, the movable end 102 is connected to the fixed end 101 via a first spring 801 , and the pull rope 802 is fixedly connected to the movable end 102 .

[0026] Principle of use: Before use, the first spring 801 is in a normal state. At this time, the cuff 3 is stretched and pressed against the occluder tube body 1. The pull rope 802 pulls the movable end 102, and the first spring 801 contracts, causing the cuff 3 to become loose, thereby using the pre-inflated airbag 4 to inflate the cuff 3, thereby achieving bronchial obstruction. When the operation is completed, the cuff 3 is first deflated, and then the pull rope 802 is loosened. The elastic force of the first spring 801 is released, causing the occluder tube body 1 in the cuff 3 to return to an extended state. The cuff 3 is stretched to make it close to the occluder tube body 1, making it easier to remove it from the patient's body. With this arrangement, gas can enter the cuff 3 through the gap between the first springs 801, so there is no need to open an additional through hole.

[0027] In a specific embodiment, Figure 3 As shown, a connecting member 7 is provided on the sliding sleeve of the movable end 102 and the fixed end 101 , and an air outlet 701 is provided on the connecting member 7 .

[0028] Due to the flexibility of the first spring 801 itself, it is easy to bend and the direction cannot be well controlled during actual use. In order to improve the insertion efficiency when inserting the occluder into the bronchus, a connecting piece 7 is provided on the sliding sleeve of the movable end 102 and the fixed end 101, so that the movable end 102 moves in the same direction as the fixed end 101 under the action of the connecting piece 7, thereby improving the operation efficiency. The gas in the occluder tube body 1 can enter the cuff 3 through the air outlet 701.

[0029] In a specific embodiment, Figure 2 、 Figure 3As shown, a limiting tube 806 is provided in the plug tube body 1, the pull rope 802 is provided in the limiting tube 806, a fixing tube 501 is provided through the Y-shaped connecting tube 5, and the limiting tube 806 is connected to the fixing tube 501.

[0030] During actual use, by setting the pull rope 802 in the limiting tube 806, the pull rope can be prevented from accumulating in the occluder tube body 1 and affecting the normal use of the occluder. The end of the pull rope 802 away from the spring 802 passes through the fixed tube 501, making it convenient for medical staff to operate the pull rope 802.

[0031] In a specific embodiment, Figure 2 As shown, a fixing ring 803 is provided at one end of the pull rope 802 away from the first spring 801, and a first limiting rod 804 and a second limiting rod 805 are provided on the fixing tube 501. The first limiting rod 804 and the second limiting rod 805 are both used to fix the pull rope 802.

[0032] During actual use, the first limiting rod 804 is set away from the tube mouth of the fixed tube 501, and the second limiting rod 805 is set close to the tube mouth of the fixed tube 501. Before inserting and removing the obturator, the first spring 801 is in a normal state. At this time, the fixing ring 803 is sleeved on the second limiting rod 805, which can prevent the pull rope 802 from entering the obturator tube body 1. When the obturator is inserted into the appropriate position, pull the pull rope 802 and sleeve the fixing ring 803 on the first limiting rod 804 to ensure that the first spring 801 is continuously in a compressed state, so that the cuff 3 can be inflated. During this process, medical staff do not need to continuously pull the pull rope 802.

[0033] In a specific embodiment, Figure 1 As shown, a control valve 6 is provided on the fixed pipe 501, and the control valve 6 is used to control the connection state between the fixed pipe 501 and the external environment.

[0034] In actual use, the control valve 6 can be a sealing cap provided at the mouth of the fixed tube 501. The sealing cap should be made of rubber material. By providing the control valve 6, the gas can be prevented from being discharged from the fixed tube 501 when the cuff 3 is inflated.

[0035] In a specific embodiment, Figure 5 As shown, the control valve 6 includes a housing 601 , a valve core 604 is provided in the housing 601 , a channel is opened on the valve core 604 , the pull rope 802 is passed through the channel, and the control valve 6 also includes a second spring 602 .

[0036] During actual use, the pressing part 603 is squeezed to connect the channel with the fixed tubes 501 at both ends, so that the pull rope 802 can be pulled smoothly. The pressing part 603 is released, and under the elastic force of the second spring 602, the channel and the fixed tubes 501 at both ends are dislocated, so that the fixed tubes 501 are no longer connected to the external environment. The valve core 604 can be made of rubber material, which can prevent the pull rope 802 from hindering the resetting of the valve core 604.

[0037] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
