[0023] The following will cooperate with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] As Figures 1 - 4 shown, the endoscope for gastrointestinal tract insertion provided in this embodiment includes an operating handle 1. One end of the operating handle 1 is threadedly connected to a tail end connector 2. The end of the tail end connector 2 away from the operating handle 1 is fixedly connected to an insertion tube 3. A camera 4 and an LED lamp 5 are fixedly installed at the head end of the insertion tube 3. And a leak detection valve 6 is fixedly installed on one side of the operating handle 1. The head end of the insertion tube 3 is set to curl upwards, which can prevent the insertion tube 3 from scratching the gastric mucosa of the patient. First, cover the head end of the insertion tube 3 of the endoscope, then connect the leak detection device, and apply a pressure of 22 kPa for 3 minutes without air leakage. Immerse the endoscope completely in water, and use a syringe to inject water into each pipeline to discharge the gas in the pipeline; First, bend the front end of the endoscope in all directions and observe whether there are air bubbles emerging; Then observe whether there are air bubbles emerging in parts such as the operating handle 1, the insertion tube 3, and the tail end connector 2; If leakage is found, it should be recorded in time and sent for repair and inspection, so as to prevent the endoscope from leaking during use and affecting the safety of the patient's examination and treatment process.

[0025] Furthermore, as Figures 1 - 4 shown, one end of the operating handle 1 away from the tail end connector 2 is fixedly connected to a data cable 7, and the other end of the data cable 7 is fixedly installed with a data cable interface 8. Through the data cable 7 and the data cable interface 8, the endoscope for gastrointestinal tract insertion can be connected to a medical endoscope image processor, and then the data photographed by the patient's gastrointestinal tract can be transmitted to the medical endoscope image processor, facilitating medical staff to see the situation inside the patient's gastrointestinal tract and make judgments and decisions.

[0026] Furthermore, as Figures 1 - 4As shown, a rotating shaft 9 is rotatably provided inside the operating handle 1, and a double gear sleeve 10 is fixedly mounted on the rotating shaft 9. The double gear sleeve 10 is meshed and connected with the teeth on the operating handle 1. A driving gear 11 is provided on one side of the double gear sleeve 10. The driving gear 11 is fixedly connected to the rotating shaft 9. One end of the rotating shaft 9 is rotatably connected to the inner side wall of the operating handle 1, and the other end of the rotating shaft 9 passes through the operating handle 1 and is fixedly connected with a pull rod 12. The pull rod 12 is rotatably provided on the outer side of the operating handle 1 through the rotating shaft 9. A limit plate 13 is meshed and connected on the driving gear 11.
