Description

Technical Field

[0001] The utility model relates to the technical field of gastroscopy and colonoscopy examinations, and specifically relates to an auxiliary suction and hemostasis device for emergency gastroscopy and colonoscopy examinations. Background Art

[0002] Digestive tract bleeding is a common acute and critical disease in clinical practice. Upper gastrointestinal bleeding refers to the digestive tract bleeding from the starting part of the esophagus to the Treitz ligament of the duodenum, and is most commonly seen in peptic ulcer, esophageal and gastric varices, and tumor bleeding. Acute upper gastrointestinal bleeding often presents with hematemesis and melena as the first manifestations, and hematemesis is its characteristic manifestation. According to the bleeding speed, bleeding volume, and bleeding site, its clinical manifestations are also different. When bleeding rapidly and in large amounts, it can also present as hematochezia, and even hemorrhagic peripheral circulatory failure. The annual incidence of acute upper gastrointestinal bleeding in adults is 100 / 100,000 - 180 / 100,000, and the fatality rate is 2% - 15%. Lower gastrointestinal bleeding refers to the bleeding in the intestinal tract below the Treitz ligament at the transition part of the duodenum and jejunum. Acute lower gastrointestinal bleeding is mainly characterized by sudden hematochezia accompanied by hemodynamic abnormalities, and the incidence accounts for about 20% of all digestive tract bleeding.

[0003] Digestive endoscopy has the advantages of being intuitive, allowing direct endoscopic treatment, and being relatively safe, and is considered the preferred examination and treatment method for digestive tract bleeding. For acute non-variceal upper gastrointestinal bleeding, the current guidelines recommend endoscopic examination within 24 hours after bleeding without contraindications. Delayed endoscopic examination in acute upper gastrointestinal bleeding patients for more than 24 hours is associated with an increased fatality rate. Emergency endoscopic examination should be performed on patients with persistent hemodynamic instability after active resuscitation. Blood, blood clots, etc. remaining in the gastrointestinal tract after digestive tract bleeding are the main problems faced in gastroscopy and colonoscopy examinations. Coupled with the acute onset of digestive tract bleeding and the lack of time for fasting / intestinal lavage and other preparations before gastroscopy and colonoscopy examinations, there are retained food residues and feces. Therefore, the retention of fluid, blood, blood clots, food residues, and fecal residues in the gastrointestinal tract is the main reason affecting the endoscopic field of view in emergency gastroscopy and colonoscopy examinations and making it difficult to detect bleeding lesions. How to quickly aspirate and remove the fluid and blood in the gastrointestinal tract and expose the lesions during the endoscopic examination is the key during the endoscopic hemostasis process. However, the general aperture of the biopsy channel of existing gastroscopes and colonoscopes is 2.0 mm - 3.7 mm. During endoscopic examination, only air and some impurity-free liquids can be aspirated, and it is difficult to aspirate and remove blood clots, food residues, etc. After inserting accessories, the aspiration becomes more difficult due to the smaller biopsy channel. Therefore, conventional endoscopes will spend a lot of time clearing the fluid, blood, blood clots, food residues, and fecal residues in the gastrointestinal tract during emergency gastroscopy and colonoscopy examinations, affecting the exposure of bleeding lesions, thereby prolonging the time of emergency gastroscopy and colonoscopy examinations and increasing the treatment difficulty. Naturally, the occurrence of complications such as bleeding, abdominal distension, perforation, aspiration, and pharyngeal injury in patients also increases. Content of the Utility Model

A C-shaped front-end channel 2 is provided in the lower half of the front end of the transparent cap 1, and the C-shaped front-end channel 2 communicates with the hollow U-shaped structure 6 that fits the gastroscope tube 5. The inside of the transparent cap 1 fits the front end 3 of the gastroscope. The transparent cap 1 and the hollow U-shaped structure 6 are integrally manufactured from silicone material. The hollow U-shaped structure 6 is designed in a U shape to conform to the circular structure of the gastroscope body, so that it can be easily embedded in the gastroscope body with less increase in the gastroscope diameter and without affecting the operation. A circular side hole with a diameter of about 1.0 cm is designed at a position 2.0 cm from the rear end of the transparent cap near the hollow U-shaped structure 6. The large aperture can effectively suck. The front end of the hollow U-shaped structure 6 is the transparent cap 1. The lower half of the transparent cap 1 is a C-shaped hollow structure channel, which communicates with the hollow U-shaped structure 6, facilitating the suction of air and liquid. The upper half of the transparent cap 1 is a solid structure. There is a side hole, namely the first side hole 4, in the middle of the upper half circle of the transparent cap. When the liquid flows into the suction sleeve of the transparent cap and blocks the endoscopic view, the side hole is brought into contact with the mucosal tissue to facilitate the outflow of the liquid. The rear end of the transparent cap 1 is provided with a hollow U-shaped structure 6 that fits the gastroscope tube 5. The hollow U-shaped structure 6 that can be externally connected to a negative pressure aspirator for auxiliary suction and the hemostasis device transparent cap 1 are integrated. The transparent cap 1 can be directly installed on the front end 3 of the gastroscope, and the hollow U-shaped structure 6 is directly embedded in the mirror body, which is convenient and simple and does not affect the endoscopic operation. The front end of the transparent cap 1 is provided with a C-shaped front-end channel 2 and a large-diameter second side hole 7 in the hollow U-shaped structure 6, which can effectively suck and remove the accumulated fluid, blood, blood clots, food residues, and fecal residues in the gastrointestinal tract, expose the bleeding lesion, and can perform hemostasis operation while sucking, improve the vision during the hemostasis operation, shorten the hemostasis time, and increase the hemostasis success rate. It is easy to clean and disinfect: sterile packaging, single-use, soft in texture, and can be used for emergency gastrointestinal examinations, hemostasis, foreign body removal, and even EMR and ESD surgical treatments.

[0018] Working principle: During the operation, the operator uses the hollow U-shaped structure 6 that can be externally connected to a negative pressure aspirator for auxiliary suction and the transparent cap 1 for auxiliary hemostasis treatment and improving the visibility of difficult-to-observe parts, which are integrated. A second side hole 7 with a diameter of 1.0 cm is opened at a position 2.0 cm from the rear end of the transparent cap 1 near the hollow U-shaped structure 6. The large aperture can effectively suck and remove the accumulated fluid, blood, blood clots, food residues, and fecal residues in the gastrointestinal tract. And the front end of the transparent cap 1 connected to the hollow U-shaped structure 6 is a C-shaped front-end channel 2, which can effectively suck air and liquid, and can perform hemostasis operation while sucking. In summary, the hollow U-shaped structure 6 that can be externally connected to a negative pressure aspirator for auxiliary suction and the hemostasis device transparent cap 1 can effectively suck and remove the accumulated fluid, blood, blood clots, food residues, and fecal residues in the gastrointestinal tract, expose the bleeding lesion, and can perform hemostasis operation while sucking.
