Technical Field

[0001] The utility model relates to the technical field of endoscope tip caps, in particular to an endoscope tip airbag device. Background Art

[0002] The small intestine is the longest digestive tract in the human body. It is located in the middle of the digestive tract. The total length of an adult is about 5 to 7 meters. It is very far from the mouth and anus. The small intestine lumen is long, free, and tortuous, making it difficult to insert an endoscope and observe. The special anatomical structure of the small intestine brings certain difficulties to the diagnosis of diseases. The colon is M-shaped, with a total length of about 130cm, and is divided into the ascending colon, transverse colon, descending colon, and sigmoid colon. Because the digestive tract is relatively long, when observing some special parts (such as the horizontal part of the duodenum and below, and deeper at the end of the ileum), the tip cap is inserted into the end of the endoscope to protect the endoscope lens.

[0003] When removing foreign bodies from the esophagus through endoscopy, due to the narrow esophageal cavity, some foreign bodies with sharp ends often pierce the esophageal walls on both sides, making removal difficult or causing other more serious complications such as bleeding, perforation, etc., which increases the patient's surgical pain. Utility Model Content

[0026] Embodiment 1: In order to solve the problem that some foreign bodies with sharp ends in the prior art often pierce the esophageal wall on both sides, causing difficulty in removal or other more serious complications such as bleeding, perforation, etc., and increasing the pain of surgery for patients, the following technical solution is disclosed, see Figure 1 , Figure 2 and Figure 4 As shown, the airbag body 4 is connected to the outside of the tip cap body 1, and an airbag inflation tube 5 is installed at the right lower end of the airbag body 4, and an inflation connector 6 is installed at the end of the airbag inflation tube 5, the upper end of the tip cap body 1 protrudes from the upper end of the airbag body 4, and the airbag body 4 is inflated by the airbag inflation tube 5;

[0027] When removing foreign bodies from the esophagus through endoscopy, the inflation connector 6 is connected to the inflation instrument. The inflation instrument is inflated so that the gas enters the balloon body 4 through the balloon inflation tube 5, thereby expanding the balloon body 4. The balloon body 4 expands and the esophageal cavity is expanded. At this time, the foreign bodies piercing the esophageal wall on both sides will loosen or fall off, which is conducive to subsequent removal. When the endoscope is inserted, the balloon body 4 is also inflated so that the balloon body 4 fills the intestinal cavity to achieve the effect of fixing the intestinal cavity. At this time, the endoscope is slowly pulled back to straighten the previous looped part and fold the intestinal tube into the outside of the endoscope body. Repeating the operation multiple times can reach the target part.

[0028] Embodiment 2: This embodiment can use the tip cap body 1 with airbag inflation tubes 5 of different diameters, see Figure 2 and Figure 3 As shown, a tip airbag device for endoscope includes a protrusion 2, which is adhered to the lower end of the tip cap body 1, and the tip cap body 1 is hollow inside, and the tip cap body 1 is inserted into the upper end of the endoscope body 3; it also includes: the tip cap body 1 is made of transparent rubber material, the airbag body 4 is made of elastic latex material, the airbag inflation tube 5 is a hose, the protrusion 2 is made of solid elastic latex material, and the outer diameter of the protrusion 2 is smaller than the outer diameter of the tip cap body 1, the length of the airbag inflation tube 5 has three specifications of 1.6m, 2.3m and 2.6m respectively, and the diameter of the airbag inflation tube 5 is 1mm-1.5mm, and the upper end of the tip cap body 1 is a sealing structure;

[0029] The material of the tip cap 1 can soften the exterior of the endoscope body 3. During the process of inserting the tip cap 1 into the endoscope body 3, the tip cap 1 contacts the interior of the body, reducing the force to protect the interior. The setting of the tip cap 1 will not affect the endoscope body 3's photographing of the interior. The material of the protrusion 2 is elastic, so that the protrusion 2 can be interlocked with endoscope bodies 3 of different diameters, thereby expanding the use range of the tip cap 1.

[0030] Embodiment 3: In order to facilitate the phenomenon that the endoscope body 3 fogs up inside the stomach when using the device, please refer to the attached Figure 1 and attached Figure 5The tail end of the airbag inflation tube 5 is bifurcated to connect the first airway 501 and the second airway 502. The gases between the first airway 501 and the second airway 502 do not affect each other. The end of the airbag inflation tube 5 is provided with a control valve 503 through which the gas can flow to the first airway 501 and the second airway 502. The head end of the first airway 501 is connected to the inside of the airbag body 4, and the end of the second airway 502 is extended to the inside of the endoscope body 3. The endoscope body 3 is provided with an air outlet 7 near the lens side. When the endoscope body 3 is in the gastrointestinal tract, the gas outlet 7 is opened. When the lens is inside the endoscope body 3, the temperature difference between hot and cold may easily cause fogging of the lens. At this time, the pump body connected to the inflation joint 6 is used to supply gas, so that the gas can be transported through the airbag inflation tube 5. The setting of the control valve 503 can control the flow direction of the gas. At this time, the gas no longer flows into the first air pipe 501, but is only transported through the second air pipe 502. The gas can be transported to the inside of the air outlet 7, and the lens of the endoscope body 3 is blown through the air outlet 7 to prevent the lens from fogging.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
