[0002] Esophageal ultrasonic endoscope is a common clinical examination method, since ultrasonic wave needs to spread by water medium, therefore, when using ultrasonic small probe to carry out esophageal ultrasonic endoscope examination, water needs to be injected in esophageal cavity, so that clear ultrasonic image can be produced.
[0003] In the process of inserting the ultrasonic endoscope into the patient's esophagus for examination, the lens surface of the endoscope will inevitably adhere to a layer of mucus. The mucus adhering to the lens will interfere with the transmission and reflection of ultrasonic waves, causing the image to become blurred or distorted, affecting the doctor's observation of the internal structure of the esophagus and the accuracy of diagnosis. Moreover, the mucus on the lens will increase the difficulty of operation during the examination process, and the doctor needs to spend more time and effort to remove the mucus or adjust the lens position to ensure that a clear image is obtained. This not only prolongs the examination time, but also may increase the discomfort of the patient. SUMMARY

[0008] An air injection pipe is communicated outside the first air bag, which is used for injecting air into the first air bag and the second air bag, so that they are in a state of fullness and adhere to the inner wall of the esophagus.
[0009] Further, a water injection cavity is formed between the first air bag, the second air bag and the inner wall of the esophagus.

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0024] Please refer to Figures 1-4 The embodiment of the present application is a kind of esophageal ultrasonic endoscopy device based on double air bag structure, which is used to protect ultrasonic probe 2 when ultrasonic endoscope is extended to the inside of esophagus, to prevent the lens surface from adhering to mucus during the extension process;
[0025] Specifically, it includes ultrasonic pipeline 1, ultrasonic probe 2, first air bag 3 and second air bag 4.
[0026] Ultrasonic probe 2 is installed at the bottom of ultrasonic pipeline 1, and transmission line connected with ultrasonic probe 2 electrically is arranged inside ultrasonic pipeline 1;First air bag 3 is sleeved outside ultrasonic pipeline 1, and at least two gas path pipelines 5 are vertically communicated outside first air bag 3, second air bag 4 is communicated at one end of at least two gas path pipelines 5 away from first air bag 3, and the top of second air bag 4 is concave downward to form an inner recess 401, so that ultrasonic pipeline 1 and ultrasonic probe 2 can be inserted into the inside of second air bag 4.
[0027] In the actual use process, ultrasonic probe 2 at the end of ultrasonic pipeline 1 is inserted into inner recess 401 inside second air bag 4, at this time, second air bag 4 is wrapped outside ultrasonic probe 2, so as to protect ultrasonic probe 2, effectively preventing the mucus inside esophagus from adhering to ultrasonic probe 2.
[0028] In the actual extension process, in order to facilitate the observation of the inside of esophagus, the preferred second air bag 4 in the embodiment is made of transparent plastic material.
[0029] Further, when it is necessary to take pictures of the position of the lesion, a gas injection pipe 6 is communicated outside first air bag 3 in the embodiment, so as to inject gas into first air bag 3 and second air bag 4, so that they are in a state of fullness and adhere to the inner wall of esophagus.
[0030] In the actual use process, gas injection pipe 6 is communicated with gas supply equipment in the outside world, and first air bag 3 is injected with gas through the gas supply equipment, at the same time, the gas pressure is transmitted to the inside of second air bag 4 through two gas path pipelines 5, so that first air bag 3 and second air bag 4 are in a state of fullness, at the same time, first air bag 3 and second air bag 4 adhere to the inner wall of esophagus at the same time, so that a water injection cavity is formed between first air bag 3, second air bag 4 and the inner wall of esophagus.
[0031] Further, when the first air bag 3 and the second air bag 4 are attached to the inner wall of the esophagus, the ultrasonic tube 1 is pulled to move the ultrasonic probe 2 out of the inner recess 401 inside the second air bag 4, so as to take pictures of the lesion.
[0032] Preferably, in order to improve the clarity of the picture, a water injection pipe 7 is arranged inside the ultrasonic tube 1 and extends to the water injection cavity.
[0033] In actual use, the water injection pipe 7 is connected to a water supply device, water is supplied to the water injection pipe 7 through the water supply device, and the water is delivered to the inside of the water injection cavity through the end of the water injection pipe 7, so that the inside of the water injection cavity is filled with clean water solution, thereby improving the clarity of the ultrasonic picture.
[0034] In actual setting, in order to prevent the ultrasonic tube 1 from falling off from the inside of the first air bag 3, a limiting ring 8 is fixedly sleeved on the outside of the ultrasonic tube 1 and close to the bottom thereof, and the outer diameter of the limiting ring 8 is greater than the inner diameter of the first air bag 3.
[0035] Specifically, in order to realize the sliding connection of the first air bag 3 and the ultrasonic tube 1, a through hole is vertically formed in the first air bag 3, and the inner diameter of the through hole is matched with the outer diameter of the ultrasonic tube 1, so that the first air bag 3 can move up and down along the extension direction of the ultrasonic tube 1.
[0036] In actual setting, the inside of the first air bag 3 and the inner recess 401 are made of plastic material with certain hardness, that is, when the first air bag 3 is inflated, the first air bag 3 will not press the inside of the ultrasonic tube 1, effectively preventing the ultrasonic tube 1 from moving with the first air bag 3 and the second air bag 4.
[0037] Preferably, in order to prevent mucus inside the esophagus from entering the inner recess 401 through the gap between the inner recess 401 and the ultrasonic tube 1 during extension, the inner diameter of the inner recess 401 is matched with the outer diameter of the ultrasonic tube 1.
[0038] In actual setting, by ensuring that the inner diameter of the inner recess 401 is matched with the outer diameter of the ultrasonic tube 1, the gap between them can be minimized, and this close fit helps to prevent mucus inside the esophagus from seeping into the inner recess 401 through the gap during use of the device, effectively keeping the device clean.
