[0002] In life, there are often patients with foreign objects stuck in the esophagus. Most patients with foreign objects stuck in the esophagus will go to the hospital for treatment. For foreign objects stuck in the esophagus, most doctors will directly remove them with forceps. When using forceps to remove the foreign objects, the doctor cannot observe the internal situation of the esophagus, and there is a risk of scratching the esophagus when removing the foreign objects.

[0003] A Chinese patent discloses an extraction method for a foreign body extraction device for children's digestive tract (publication number: CN113288379A). The patented clamp assembly can be hidden inside the extraction shell under the cooperation of the extraction assembly and the linkage rod. The extraction shell is cylindrical and easier to insert into the digestive tract of the child, reducing the discomfort of the child during treatment. The clamp assembly of the device automatically opens after extending from the inside of the extraction shell. When clamping a foreign body, it can first clamp and then shrink, driving the foreign body to also shrink into the inside of the extraction shell, making it convenient to remove the device and the foreign body, reducing the discomfort caused during treatment, and having strong comfort and easy use, thereby improving the practicality and flexibility of the device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the electromagnet blocks are turned on in sequence, and the polarities of the electromagnet blocks close to each other are made the same. At this time, the distance between the electromagnet blocks connected by the memory metal spiral ring will increase. In this way, the soft steel fork can be extended out of the guide tube, so that the soft steel fork can pass through the foreign body in the esophagus. When the foreign body is between the soft steel forks, the electromagnet disk is energized. At this time, the electromagnet disks will attract each other and then wrap the foreign body.

In this way, the collection tube can be slowly and steadily advanced, thereby avoiding the collection tube from entering too fast or too slow to cause discomfort to the patient, and at the same time avoiding the collection tube from damaging the esophagus too fast.

[0018] 3. When the present invention is used, the electromagnet block is repeatedly powered on and off. When the electromagnet block is powered on, the one-way valve will be adsorbed. When the one-way valve is adsorbed, the negative pressure membrane will be lifted up. When the electromagnet block is powered off, the negative pressure membrane will press the one-way valve to reset. When the negative pressure membrane is lifted up, air will enter the reserved groove inside the guide tube through the air inlet window. When the negative pressure membrane is reset, the air in the internal reserved groove will be sent to the reserved groove outside the guide tube. This can be repeated to make the soft membrane bulge, thereby expanding the esophagus, avoiding foreign objects scraping the esophagus and causing esophageal damage when removing foreign objects, and is not limited by the size of the foreign objects.

[0019] 4. When the present invention is used, when the probe contacts a foreign object, it will push against the support tube, causing the limiting rod to squeeze the soft steel fork, thereby limiting the soft steel fork, preventing the electromagnet block from affecting the soft steel fork when it is energized again to inflate the soft membrane.

[0038] The working principle of the present invention is: When the present invention is used, the patient places his chin on the upper end of the support plate 3 and then adjusts the adjustment rod 2 to raise the support plate 3 so that the patient's head is tilted up, so that the deep part of the oral cavity and the esophagus are in the same vertical line (the real meaning here is to make the deep part of the oral cavity and the esophagus in the same vertical line as much as possible), which is convenient for extracting foreign matter, and then rotates the support frame 4 so that the guide tube 7 is located obliquely above the patient's oral cavity, thereby facilitating the extraction tube 6 to enter the patient's oral cavity; Then, the rotating sleeve 702 is rotated to drive the paddle 705 to rotate. At this time, the paddle 705 moves along the thread groove 601 on the outer wall of the extraction tube 6. Since the paddle 705 can only rotate by itself, when the paddle 705 rotates along the thread groove 601, it drives and pushes the extraction tube 6 to move into the patient's oral cavity, thereby making the extraction tube 6 penetrate into the patient's esophagus. In this way, the extraction tube 6 can be slowly and steadily pushed forward, thereby preventing the extraction tube 6 from entering too fast or too slow to cause discomfort to the patient, and preventing the extraction tube 6 from damaging the esophagus at too fast a speed. Then, the internal situation of the patient's esophagus can be observed through the probe 602. When the probe 602 approaches the foreign body in the esophagus, the rotating sleeve 702 is stopped; Then, the electromagnet blocks 618 are turned on, and the polarities of the electromagnet blocks 618 that are close to each other are controlled to be the same. In this way, the electromagnet blocks 618 connected by the memory metal spiral ring 619 will move away from each other, while the distance between the electromagnet blocks 618 connected by the support rod 620 will not change. When turning on the electromagnet blocks 618, the electromagnet blocks 618 close to the guide tube 600 should be turned on first. Even if the electromagnet blocks 618 are turned on one by one in sequence, the extension distance of the memory metal spiral ring 619 can be controlled by controlling the magnetic size of the electromagnet blocks 618. In this way, the soft steel fork 610 can be extended out of the guide tube 600. When the soft steel fork 610 is extended to a suitable length, the electromagnet block 618 is closed, so that the soft steel fork 610 can pass through the foreign body in the esophagus. For foreign bodies that cannot pass through, the retrieval tube 6 can be manually adjusted in the oral cavity to keep the foreign body between the soft steel forks 610 when the soft steel fork 610 is extended (the specific operation method can be determined based on the image observed by the probe 602). When the foreign body is between the soft steel forks 610, the electromagnet disk 617 is energized, and the electromagnet disks 617 will attract each other, and then wrap the foreign body. Fig.13 ; And by pushing the observation plate 407, the use status of the electromagnet block 618 near the cylinder 700 can be observed. When the electromagnet block 618 is turned on, it will absorb the iron sand in the observation plate 407, and then the iron sand can reflect whether the electromagnet block 618 is turned on normally; After the soft steel fork 610 wraps around the foreign body, the rotating sleeve 702 is rotated to drive the retrieval tube 6 to continue to go deeper into the esophagus until the probe 602 hits the foreign body. After the probe 602 hits the foreign body, the probe 602 pushes the support tube 611. After the support tube 611 is pushed, it pushes a plurality of limiting rods 614. At this time, the limiting rods 614 clamp the column soft steel fork 610, thereby limiting the soft steel fork 610. Moreover, the cooperation between the guide tube 600 and the soft steel fork 610 can clamp the foreign body more tightly, so as to prevent the foreign body from falling when the retrieval tube 6 is taken out. Then, the electromagnet block 618 is repeatedly powered on and off. When the electromagnet block 618 is powered on, the one-way valve 606 is adsorbed. When the one-way valve 606 is adsorbed, it moves toward the electromagnet block 618, and at this time, the negative pressure membrane 615 is lifted up. When the electromagnet block 618 is powered off, the negative pressure membrane 615 presses the one-way valve 606 to reset. When the negative pressure membrane 615 is lifted up, air will enter the reserved groove 604 inside the guide tube 600 through the air inlet window 616. When the negative pressure membrane 615 is reset, the internal reserved groove 604 will be filled. 04 is sent into the reserved groove 604 outside the guide tube 600, and this repetition can make the soft membrane 603 bulge, thereby expanding the esophagus, and preventing the foreign body from scratching the esophagus and causing esophageal damage when removing the foreign body (specifically, the negative pressure membrane 615 is a mobile silicone membrane, and when the negative pressure membrane 615 expands, the air inlet window 616 will expand, thereby increasing the amount of air intake, and when the negative pressure membrane 615 contracts, the air inlet window 616 will shrink, thereby reducing the exhaust gas, allowing most of the air to enter the reserved groove 604 outside the guide tube 600); After the extraction tube 6 has removed the foreign matter, the wheel body 500 can be directly rotated to be rolled up, and then the heating block 501 can be turned on to heat the extraction tube 6 to restore the internal memory metal spiral ring 619 to its shape. Finally, the entire wheel body 500 can be removed and placed in a disinfection device for disinfection, so as to facilitate next use.
