[0034] In this embodiment, reference Figure 5The inner circle of the curved tube 6 is provided with an elbow adjustment mechanism 1, and the curved tube 6 is in a curved state, which is the maximum degree of bending of the traditional left-side double-lumen endotracheal tube elbow. Then, by enhancing the mechanical strength of the elbow adjustment mechanism, the curved tube 6 is driven to gradually straighten, so as to achieve the purpose of changing the bending degree of the curved tube 6. The elbow adjustment mechanism 1 is fitted on the inner wall of the curved left side of the curved tube 6. The elbow adjustment mechanism 1 includes a pull rope 22, a guide bamboo joint 23 and a guide cylinder 24. The left side of the guide bamboo joint 23 is fixedly installed on the inner wall of the left side of the curved tube 6.

[0035] In the utility model, the installation steps of the visual double-lumen endotracheal tube are as follows:

[0036] Step 1: The end of the metal guide wire 3 is inserted into the deep of the curved tube 6 through a branch tube 2 and the left cavity 13 to straighten the curved tube 6 to reduce the situation where the curved tube 6 irritates the inner wall of the main bronchus. The head end of the metal guide wire 3 is bent into a U shape and inserted into another branch tube 2;

[0037] Step 2: Through the micro camera 1 10 and the micro camera 2 15 and the connected display screen, the front side of the micro camera 1 10 and the micro camera 2 15 can be photographed and displayed in real time, so as to assist the doctor to smoothly insert the visual double-lumen endotracheal tube into the patient's bronchus at one time. After the visual double-lumen endotracheal tube is inserted into the main bronchus, the metal guide wire 3 in step 1 needs to be pulled out;

[0038] Step 3: The position of the left bronchus is determined by the bending direction of the inner wall of the left bronchus photographed by the micro camera 10 or the position of the carina photographed by the micro camera 2 15, and the doctor manually pulls the head end of the outer pull rope 22, so that the end of the pull rope 22 pulls the top of the guide bamboo section 23 to gradually close according to a plurality of V-shaped folding openings, driving the curved tube 6 to straighten, thereby changing the bending degree of the curved tube 6, so that the curved tube 6 faces the left bronchus, so that an inexperienced doctor can also insert the curved tube 6 into the left bronchus at one time;

[0039] Step 4, after the curved tube 6 is inserted into the left bronchus, the cuff 1 7 is inflated through a thin catheter to block the inner cavity of the left bronchus, and then the cuff 2 8 is inflated through a thin catheter to block the main bronchus, and the oblique opening 5 is aimed at the right bronchus, thereby temporarily isolating the ventilation of the left and right bronchi.

[0040] Among them, when the visual double-lumen endotracheal tube is inserted into the bronchus, when the sputum generated by the stimulation blocks the micro camera 10 or the micro camera 2 15, gas or liquid can be sprayed through the capillary 2 16 or the capillary 11 to flush the lens of the micro camera 10 or the micro camera 2 15, so as to keep the lens of the micro camera 10 or the micro camera 2 15 clean. It is mainly used to clean the sputum generated when the main bronchus is stimulated, and by squeezing the air bag ball 2 20 or the air bag ball 3 21, it can be inflated into the bag cushion 18 or the bag cushion 2 19 through the gas guide tube respectively, so as to change the volume and expansion degree of the gas in the bag cushion 18 or the bag cushion 2 19, thereby lifting the front end or the rear end of the micro camera 10, so as to achieve the purpose of adjusting the shooting direction of the micro camera 10, and combined with the flushing of the capillary 11, the lens of the micro camera 10 can be cleaned from different angles, so that the camera adjustment mechanism also has the function of assisting in cleaning the lens of the micro camera 10.

[0041] Embodiment 2: The difference from Embodiment 1 is that the elbow direction adjustment mechanism 1 in the curved pipe 6 is replaced by the elbow direction adjustment mechanism 2.

[0042] See attached Figure 6 The second elbow adjustment mechanism includes two airbag strips 9 parallel to each other. The outer walls of the airbag strip 9, the airbag cushion 1 18 and the airbag cushion 2 19 in the present application are made of non-elastic materials. When the airbag strip 9 is not subjected to the elastic bending pressure of the bend tube 6 in the natural state, it is in a straight state;

[0043] Two airbag strips 9 are fixedly installed in parallel on the inner wall of the curved tube 6. The ends of the two airbag strips 9 are fixedly connected with an airbag ball 4 through an air-conducting capillary. An independent closed environment is formed between the two airbag strips 9 and the airbag ball 4. The air-conducting capillary is fixedly installed on the inner wall of the left cavity 13, and passes through the double-cavity main tube 1 from the inner wall of the head end of the left cavity 13. The airbag ball 4 is located on the outside of the double-cavity main tube 1. By manually pinching the airbag ball 4, the gas in the airbag ball 4 is pressed into the airbag strip 9, thereby increasing the mechanical strength of the airbag strip 9, supporting the curved tube 6, and achieving the purpose of changing the bending degree of the elbow.
