Description

Technical Field

[0001] The utility model relates to the technical field of insertion tubes, in particular to a gastroscope insertion tube. Background Art

[0002] Under normal circumstances, gastroscopy requires intubation. During gastroscopy, a slender tube equipped with an endoscope is used to enter the stomach through the esophagus in the mouth to observe the specific condition of the stomach. Gastroscopy has diagnostic significance for various stomach diseases. During the examination, some tissues can be extracted for pathological examination. The examination method requires intubation. The current insertion tube is easily blocked by food residues in the stomach, resulting in poor water spraying in the water spray channel and failure to flush the stomach wall, thereby affecting more detailed observation.

[0003] The existing patent (publication number: CN203417187U) proposes a gastroscope insertion tube, including a spring tube, a stainless steel woven mesh tube and a sleeve; the stainless steel woven mesh tube is sleeved on the spring tube, and the sleeve is sleeved on the stainless steel woven mesh tube. It is characterized in that tin is welded on both ends of the inner wall of the stainless steel woven mesh tube, and it is fixed together with the spring tube by soldering. The two ends of the stainless steel woven mesh tube are respectively connected to connecting rings. The utility model is flexible in operation.

[0004] The above-mentioned gastroscope insertion tube adopts a spring tube, a stainless steel woven mesh tube and a sleeve in the technical solution of flexible operation; the stainless steel woven mesh tube is sleeved on the spring tube, and the sleeve is sleeved on the stainless steel woven mesh tube. The problem with this solution is that, although it solves the flexibility of operation, it does not solve the problem of poor water spraying leading to the inability to flush the stomach wall and perform more detailed observation. Therefore, we propose a gastroscope insertion tube to solve the above problem. Utility Model Content

[0017] Preferably, the filter screen is fixed in the first water supply channel and the second water supply channel opened on the front end portion.

[0018] The above technical solution is adopted: the filter is fixed in the first water supply channel and the second water supply channel opened on the front end. When the insertion tube body is inserted into the stomach for inspection, the front end contacts the stomach wall and food residues in the stomach, which can easily cause blockage of the water supply channel at the front end, thereby making the water supply poor and resulting in unclear observation. By fixing the filter in the first water supply channel and the second water supply channel at the front end, blockage can be effectively prevented.

Through the two water supply channels, the food residues and gastric mucus remaining on the inner wall of the stomach can be quickly washed away, and the pathological conditions in the stomach can be observed in detail, which greatly improves the inspection efficiency. At the same time, the filter screen can prevent the front end from contacting and moving with the stomach wall to prevent food residues from blocking the water supply channel, thereby preventing the problem of poor water supply and inaccurate inspection. In addition, when one of the water supply channels has poor water supply, the other water supply channel can still play a role, which improves the inspection efficiency while also improving the practicality of the insertion tube.

[0021] 2. In the utility model, by providing a forceps channel, when small polyps are observed in the stomach, it is convenient to send the forceps into the stomach through the forceps channel to clamp and remove the diseased part. The gas channel can blow away the gastric mucus on the stomach wall for more convenient inspection. When the operating part is damaged, the operating ball head threadedly connected at the rear end can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS
