Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to a leak-stopping device for the gastrointestinal tract. Background Technology

[0002] Currently, gastrointestinal endoscopy has evolved from a single diagnostic tool for gastrointestinal diseases into an important device and technology integrating diagnosis and treatment. Through gastrointestinal endoscopy, some gallbladder diseases that cannot be treated with open surgery or laparoscopy, such as gallstones and gallbladder polyps, can also be effectively treated. This minimally invasive treatment not only significantly reduces surgical trauma for patients but also lowers their financial burden. However, one of the main complications of this type of treatment is the potential for puncture tract defects after stent removal, which can lead to bile leakage and, in severe cases, even endanger the patient's life.

[0003] However, current common gastrointestinal leak-sealing devices still have many shortcomings. For example, their leak-sealing effect is unsatisfactory, making it difficult to effectively prevent complications, which may adversely affect the patient's postoperative recovery and long-term health. In addition, many devices are complex to operate, increasing the difficulty of use for doctors and the treatment risks for patients. Utility Model Content

[0026] Please see Figure 1-4 ,

[0027] A gastrointestinal leak-sealing device includes an outer tube 1, inside which are two leak-sealing meshes 4, which are fixedly installed at both ends of a connector 10. Each of the two leak-sealing meshes 4 has an air bladder 11 inside, which is also installed at both ends of the connector 10. A miniature one-way valve 13 is installed on the air bladder 11 at the right end of the connector 10. The miniature one-way valve 13 is connected to a connecting tube 14. The end of the connecting tube 14 away from the miniature one-way valve 13 is inserted into an inner tube 5 and connected to a handle shaft 6. A limit plate 7 is fixedly installed on the handle shaft 6. The end of the handle shaft 6 away from the connecting tube 14 is connected to a pull ring 8. An air supply tube 9 is installed on the end of the pull ring 8 away from the handle shaft 6.

[0028] In this example, the outer ring of the right end of the outer tube 1 is provided with threads, and the right end of the outer tube 1 is provided with a fin clip 2 and a fixing nut 3. Both the fin clip 2 and the fixing nut 3 are provided with internal threads that mate with the external threads provided on the outer ring of the outer tube 1, and the fixing nut 3 is located at the right end of the fin clip 2.

[0029] It should be noted that the thread design on the outer ring of the right end of the outer tube 1 enhances the tightness and stability of the connection between the outer tube 1 and the fin clip 2 and the fixing nut 3. The inner side of the fin clip 2 is provided with an internal thread that matches the outer ring thread of the outer tube 1, so that the fin clip 2 can be tightly screwed onto the outer tube 1.

[0030] In this example, the connector 10 has through holes that cooperate with the two airbags 11. Each of the two airbags 11 has six adsorption strips 12 at the end near the connector 10. The six adsorption strips 12 are evenly distributed with the center of the airbag 11 as the reference. When the airbag 11 is fully inflated, the six adsorption strips 12 are adsorbed inside the leak-sealing mesh 4.

[0031] It should be noted that the connector 10 has through holes that cooperate with the two airbags 11. This design not only ensures that the airbags 11 can be installed smoothly and tightly connected with the connector 10, but also allows gas to enter the airbags 11 through the through holes when needed, so as to inflate and expand the airbags 11.

[0032] In this example, the rightmost end of the connecting pipe 14 is provided with an internal thread, and the left end of the connecting pipe 14 is fixedly connected to the miniature one-way valve 13. The leftmost end of the handle shaft 6 is provided with an external thread to cooperate with the internal thread of the connecting pipe 14, and the handle shaft 6 is provided with a through hole that cooperates with the connecting pipe 14.

[0033] It should be noted that the miniature one-way valve 13 is designed to control the unidirectional flow of fluid and prevent backflow or leakage, thereby ensuring the safety and effectiveness of the gastrointestinal plugging device during use. The through-hole design allows gas to enter the connecting tube 14 through the handle shaft 6 when needed, and then reach the inside of the airbag 11.

[0034] In this example, the rightmost leak-stopping mesh 4 of the connector 10 is provided with a through hole that mates with the connecting pipe 14. The inner sleeve 5 is provided at the connection between the connecting pipe 14 and the handle shaft 6, and both the handle shaft 6 and the connecting pipe 14 are movably connected to the inner sleeve 5.

[0035] It should be noted that the inner sleeve 5 is set at the connection between the connecting tube 14 and the handle shaft 6. As a transition and support structure, it can protect the connection between the connecting tube 14 and the handle shaft 6 from interference from the external environment, and also allow the handle shaft 6 to rotate or move relative to the connecting tube 14 when needed.

[0036] In this example, the handle shaft 6 passes through the center of the limiting plate 7 and is fixedly connected to the pull ring 8. The pull ring 8 is hollow inside to deliver air. Both ends of the pull ring 8 are provided with through holes that cooperate with the handle shaft 6 and the air supply pipe 9.

[0037] It should be noted that the handle shaft 6 passes through the center of the limiting plate 7. This design ensures that the handle shaft 6 remains stable when rotating or moving. At the same time, the limiting plate 7 also limits the travel of the handle shaft 6, preventing it from moving excessively or being damaged.

[0038] In summary: When using this device, first rotate the rightmost finned plate 2 of the cannula to the endoscope opening and tighten the fixing nut 3 to secure the outer cannula 1. Then, under endoscopy, guide the device through the fistula into the gallbladder. Simultaneously, while retracting the outer cannula 1, inject air into the air supply tube 9, pull ring 8, and handle shaft 6 using a syringe, causing the leftmost balloon 11 of the connector 10 to inflate. After the balloon 11 inflates, pull back the pull ring 8 to attach and fix the leftmost plugging mesh 4 of the connector 10 to the gallbladder wall. Next, pull back the outer cannula 1 again to unfold the rightmost balloon 11 and plugging mesh 4 of the connector 10 and place them tightly against the stomach wall. Finally, rotate the pull ring 8 to separate the handle shaft 6 and connecting tube 14, then retrieve the outer cannula 1, inner cannula 5, and handle shaft 6 to complete the operation. The process is scientifically and rationally designed, with simple and efficient operation steps, ensuring that the leak-sealing device can firmly fit the gallbladder and stomach wall, effectively sealing the fistula and improving the patient's treatment outcome.

[0039] Beneficial effects:

[0040] This gastrointestinal leak-sealing device, designed with two leak-sealing nets, two air bladders, and connecting components, utilizes the expansion of the air bladders to expand the leak-sealing nets within the patient's gallbladder and digestive tract. Simultaneously, the suction strip ensures the leak-sealing nets adhere firmly to the inner walls of the gallbladder and digestive tract, effectively sealing the sinus tract. The device features a simple design, convenient operation, and significantly improves the stability and effectiveness of leak sealing. The design of the inner sleeve, connecting tube, and handle shaft, utilizing external and internal threads and a pull ring, allows medical personnel to easily remove the handle shaft and inner sleeve to meet medical needs. This design not only facilitates operation but also reduces the impact of medical procedures on the patient, contributing to improved treatment outcomes and postoperative recovery.
