The multiple groups of check plates 33 pass through the insertion hole 24, are set at the inner end of the box body cavity 22, and are movably connected to the box body cavity 22.

[0037] The above scheme is adopted: the position of the insertion tube 1 can be effectively restricted by multiple sets of check plates 33, so that the insertion tube 1 can only be pushed forward and cannot be pulled back, preventing the patient from leaning back or other natural reactions when feeling uncomfortable, causing the insertion tube 1 to be pulled back and increasing the patient's discomfort. The head-mounted elastic band 34 helps to fix the check piece 3 and the oral expansion box 2 in the patient's mouth, preventing the patient from being unable to bite the oral expansion box 2 due to discomfort and causing it to fall.

[0038] Reference Figures 9 and 10 The expansion column 4 includes a connecting stud 41, a spherical block 42, a rotating disk 43 and a through hole 2 44. One end of the connecting stud 41 is fixedly connected to the spherical block 42, and the other end of the connecting stud 41 is fixedly connected to the rotating disk 43.

[0039] By adopting the above scheme: the connecting stud 41 and the spherical stop block 42 can be pushed into the box body cavity 22 by rotating the rotating disk 43, so that the spherical stop block 42 pushes open the small opening of the check plate 33, thereby releasing the position restriction of the check plate 33 on the insertion tube 1, so that the insertion tube 1 can be normally withdrawn.

[0040] The working principle of the present invention is as follows: when in use, the fixed connecting plate 1 23 and the fixed connecting plate 2 31 are first connected through the connecting jack 25 and the connecting plug block 35, and then the expansion column 4 is threadedly connected with the connecting stud 41, and the spherical block 42 is abutted against the inner wall of the check plate 33, and then the oral expansion box 2 is placed in the patient's mouth, and the patient's tongue is pressed against the lower end of the expansion box body 21, and then the head-mounted elastic band 34 is put on the patient's head to fix the oral expansion box 2 inside the patient's mouth, and then the gastroscope device is assembled, and the insertion tube 1 is picked up and inserted in sequence. The patient's stomach is entered through the expansion column 4, the check piece 3, and the oral expansion box 2. The objective lens 8 and the searchlight 9 connected to the wires and optical cables inside the insertion tube 1 are used to examine the patient's stomach with the assistance of the biopsy hole 10 and the air nozzle 11. When the examination is completed, the rotating disk 43 is rotated to make the spherical block 42 push the check plate 33 open, so that the restriction of the check plate 33 on the insertion tube 1 can be released, and the insertion tube 1 can be pulled out; the patient's tongue can be pressed against the lower end of the oral expansion box 2 through the oral expansion box 2 to prevent the position of the tongue from affecting the entry and operation of the gastroscope. By pressing the tongue, the doctor can better control the direction of entry of the gastroscope and reduce discomfort. The expansion box body 21 has a conical structure, which helps to better adapt to the shape of the inside of the oral cavity and provide a better expansion effect. The expansion box body 21 is made of colorless and odorless medical grade silicone material, which can effectively prevent the taste buds on the tongue from contacting the insertion tube 1, which will cause the patient to feel a foreign body sensation or taste discomfort and cause vomiting. The position of the insertion tube 1 can be effectively limited by multiple sets of check plates 33, so that the insertion tube 1 can only be pushed forward and cannot be pulled back, preventing the patient from When the patient feels uncomfortable, he / she may lean back or perform other natural reactions, which causes the insertion tube 1 to be pulled back, making the patient feel more uncomfortable. The head-mounted elastic band 34 helps to fix the check piece 3 and the oral expansion box 2 in the patient's mouth, preventing the oral expansion box 2 from falling due to the patient's inability to bite due to discomfort. By rotating the rotating disk 43, the connecting stud 41 and the spherical block 42 can be pushed into the box cavity 22, so that the spherical block 42 pushes open the small opening of the check plate 33, thereby releasing the position restriction of the check plate 33 on the insertion tube 1, so that the insertion tube 1 can be normally withdrawn.
