[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] See also Figure 1-5A gastroscope device, in the technical solution proposed by the utility model, comprises a gastroscope lens 1 and a connecting part 2, a scraper 31 is installed on the gastroscope lens 1, a connecting rod 32 is fixedly installed on one end of the scraper 31 located inside the gastroscope lens 1, an electric push rod 33 is fixedly installed inside the gastroscope lens 1, a connecting block 34 is fixedly installed on the output end of the electric push rod 33, a driving block 311 is fixedly installed on the connecting block 34, the driving block 311 and the connecting rod 32 are movably connected, a ratchet 35 is rotatably installed inside the gastroscope lens 1, a sliding rod 315 is inserted into the internal thread of the ratchet 35, a plug plate 312 is fixedly installed on the end of the sliding rod 315 away from the ratchet 35, a ratchet pawl 36 is rotatably installed on the connecting block 34, a liquid medicine chamber 11 is opened on the gastroscope lens 1, and a through pipe 4 is fixedly connected to the liquid medicine chamber 11;

[0028] Start the electric push rod 33. As the electric push rod 33 extends, it will push the scraper 31 to extend outward. After the scraper 31 scrapes and cleans the residue on the gastrointestinal wall, as the electric push rod 33 contracts, the scraper 31 will be retracted into the gastroscope 1. As the scraper 31 is retracted, the medicine liquid will be passively sprayed to apply medicine to the gastrointestinal wall.

[0029] Specifically, the driving block 311 is a circular block, and an oblique groove is provided on the connecting rod 32;

[0030] The size of the circular driving block 311 is matched with the size of the inclined groove. When the electric push rod 33 is started, as the electric push rod 33 drives the connecting block 34 to move, the connecting block 34 will drive the driving block 311 to move. At this time, as the driving block 311 moves in the inclined groove, it will drive the connecting rod 32 to move outward or inward.

[0031] Specifically, the slide bar 315 is in a "U" shape, and a thread groove is formed at one end of the slide bar 315 close to the ratchet 35;

[0032] When the electric push rod 33 pushes the connecting block 34 to move the scraper 31 to extend outward, the pawl 36 does not drive the ratchet 35 to rotate. When the electric push rod 33 drives the scraper 31 to retract, the pawl 36 will drive the ratchet 35 to rotate. At this time, as the ratchet 35 rotates, the ratchet 35 and the slide rod 315 are threadedly connected. At this time, the slide rod 315 will move downward in the gastroscope lens 1. At this time, the slide rod 315 will drive the plug plate 312 to move, thereby squeezing the liquid medicine in the liquid medicine chamber 11, so that the liquid medicine is sprayed out from the through tube 4.

[0033] Specifically, a slide frame 37 is slidably installed in the gastroscope 1, and a stop claw 310 is rotatably installed on the slide frame 37;

[0034] The stop claw 310 prevents the ratchet 35 from rotating in the opposite direction, so that it can only be driven by the ratchet 36 to rotate.

[0035] Specifically, a first spring 314 is fixedly installed between the pawl 36 and the connecting block 34 and between the stop pawl 310 and the sliding frame 37;

[0036] The first spring 314 enables the stop claw 310 and the pawl 36 to be reset.

[0037] Specifically, a vertical rod 38 is slidably mounted on the gastroscope 1 along its axial direction, and an abutment groove 371 is provided on the sliding frame 37;

[0038] When it is necessary to remove the plug plate 312, press the vertical rod 38 toward the gastroscope lens 1. At this time, the vertical rod 38 will push the slide frame 37 to move away from the ratchet 35 through the abutment groove 371, and at the same time, the electric push rod 33 drives the connecting block 34 to move forward, so that the pawl 36 is away from the ratchet 35. At this time, the slide bar 315 can be slid and the slide bar 315 will move outward. At the same time, the rotation of the ratchet 35 is not affected, thereby not affecting the movement of the slide bar 315, thereby facilitating the removal of the plug plate 312 and applying medicine to the medicine liquid chamber 11.

[0039] Specifically, a positioning block 39 is fixedly installed inside the gastric lens 1, and a positioning groove is provided on the side wall of the vertical rod 38;

[0040] The sliding distance of the vertical rod 38 is limited by the cooperation between the positioning block 39 and the positioning groove.

[0041] Specifically, a second spring 313 is fixedly installed between one end of the sliding frame 37 away from the ratchet 35 and the inner wall of the gastroscope 1;

[0042] When the vertical rod 38 is pressed toward the gastroscope lens 1, as the sliding frame 37 moves in the direction away from the ratchet 35, the second spring 313 will be compressed. As the vertical rod 38 is released, the second spring 313 will push the sliding frame 37 to return to its original position. At the same time, as the sliding frame 37 returns to its original position, the vertical rod 38 will also be pushed up, and the positioning block 39 will prevent the vertical rod 38 from being pushed out from the surface of the gastroscope lens 1.

[0043] Specifically, a connecting tube 21 is fixedly installed on the connecting portion 2, and the connecting tube 21 is threadedly connected to the gastroscope 1;

[0044] The connecting part 2 and the gastroscope lens 1 can be connected through the connecting tube 21, wherein a portion of the sliding rod 315 extends into the connecting part 2, wherein the soft wire control end of the gastroscope is connected to the connecting part 2 to control the movement and rotation of the gastroscope lens 1 by controlling the connecting part 2.

[0045] Specifically, a rubber sheet is fixedly installed at the opening of the through pipe 4, wherein micropores are opened on the rubber sheet;

[0046] The rubber sheet is provided with micropores to allow the liquid medicine to be sprayed out. When the liquid medicine in the liquid medicine chamber 11 is not under pressure, the micropores on the rubber sheet will not cause a large amount of liquid medicine to flow out due to the shrinkage of the rubber. Only when the plug plate 312 squeezes the liquid medicine chamber 11, the micropores on the rubber sheet will open and allow the liquid medicine to be sprayed out.

[0047] A storage cavity 12 is formed between the scraper 31 and the gastric lens 1 to store residues;

[0048] A side camera 5 is fixedly mounted on the gastroscope 1 to facilitate observation.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
