After moving to the appropriate position, the expansion airbag 3 and the first connecting component 4 are set, and the expansion airbag 3 can be expanded through the inflation of the inflation component 8. When clamping, the expansion of the expansion airbag 3 makes the operation space larger, which is convenient for clamping foreign objects. The clamping point of the removal component 9 passes through the port 2. After the iron nail is clamped, the removal component 9 drives the iron nail into the sleeve 1. At this time, through the inflation of the inflation component 8, the gas expands the closed airbag 5 through the second connecting component 6, and the expanded closed airbag 5 blocks and seals the port 2. At the same time, the iron nail can be adsorbed on the adsorption component 7. At this time, when the sleeve 1 is taken out, the iron nail will not fall out of the sleeve 1 when it falls, and will not cause scratches to the patient's esophagus, avoiding the problem that the sharp end of the iron nail may scratch the digestive tract, and will not cause secondary injury to the patient.

[0028] like Figure 2 , Figure 3 , Figure 4As shown, the first connecting component 4 includes a first mounting member 401, a first mounting member 401 is arranged on the side of the expansion airbag 3, a first air tube 402 is arranged on the surface of the first mounting member 401, and the first air tube 402 is fixedly plugged with the sleeve 1, and one end of the first air tube 402 away from the first mounting member 401 is fixedly connected with a first connecting port 403; specifically, after the sleeve 1 reaches the position of the foreign body in the patient's esophagus, the iron nail is clamped by the removal component 9, and at this time, the inflation component 8 will be connected to the first connecting port 403, and the gas generated by the inflation component 8 passes through the first air tube 402 and the first mounting member 401 to inflate the expansion airbag 3, so that the expansion airbag 3 is inflated to an appropriate degree, and at this time, the operating space of the removal component 9 will become larger, which is convenient for the removal component 9 to grasp the iron nail foreign body.

[0029] like Figure 3 , Figure 4 As shown, the second connecting component 6 includes a second mounting member 601, a second mounting member 601 is arranged on the side of the closed airbag 5, a second air pipe 602 is arranged on the surface of the second mounting member 601, and the second air pipe 602 is fixedly connected to a second connection port 603 at one end away from the second mounting member 601; specifically, after the iron nail foreign body moves to the inside of the sleeve 1, the inflation component 8 will be connected to the second connection port 603, and the gas generated by the inflation component 8 enters the inside of the closed airbag 5 through the second air pipe 602 and the second mounting member 601, so that the closed airbag 5 is expanded to an appropriate degree. At this time, the closed airbag 5 can close the port 2, so that the iron nail will not fall outward when it is removed, and thus will not cause scratch damage to the patient.

[0030] like Figure 3 As shown, the adsorption component 7 includes a magnetic block 701 and a covering member 702. The inner wall of the sleeve 1 is overlapped with the covering member 702, the inner wall of the sleeve 1 is fixedly connected with the covering member 702, and the covering member 702 is in contact with the magnetic block 701. Specifically, when the sleeve 1 is removed, the iron nail foreign body clamped by the removal component 9 is adsorbed on the magnetic block 701, and then when the port 2 is taken out, the iron nail is adsorbed on the magnetic block 701, so that the iron nail will not fall outward.

[0031] like Figure 5As shown, the inflation component 8 includes a small motor 801, and an inflation port 802 is set on the side of the small motor 801, and the inflation port 802 can be connected to the first connection port 403 and the second connection port 603; specifically, when clamping a foreign object such as an iron nail, the inflation port 802 will be connected to the first connection port 403, and the small motor 801 will work, and then the gas generated by the small motor 801 will pass through the first air pipe 402 and the first mounting member 401 to inflate the expansion airbag 3. When the foreign object is removed, the inflation port 802 will be connected to the second connection port 603, and the small motor 801 will work, and the gas generated by the small motor 801 will enter the interior of the closed airbag 5 through the second air pipe 602 and the second mounting member 601, so that the closed airbag 5 is expanded to an appropriate degree, and at this time the closed airbag 5 can close the port 2.

[0032] like Figure 2 , Figure 3 As shown, the removal component 9 includes a foreign body forceps body 901, which is arranged inside the sleeve 1, a clamp head 902 is arranged on the left side of the foreign body forceps body 901, and an operating handle 903 is arranged at one end of the foreign body forceps body 901 away from the clamp head 902; specifically, when clamping an iron nail, the iron nail is clamped by the removal component 9, and the medical staff controls the operating handle 903 to make the clamp head 902 clamp the iron nail, and then brings the iron nail into the interior of the sleeve 1 through the operating handle 903, and then the iron nail can be taken out.

[0033] like Figure 3 As shown, there are two magnetic blocks 701, and the two magnetic blocks 701 are symmetrically distributed on the inner wall of the sleeve 1; specifically, the setting of the two magnetic blocks 701 can better adsorb the nails when removing metals such as nails, so that the nails will not slip out of the sleeve 1, thereby better protecting the patient.

[0034] like Figure 1 As shown, the sleeve 1 is made of polyethylene material, and an adsorption sponge is arranged on the surface of the sleeve 1; specifically, the sleeve 1 made of polyethylene material is a soft material, which can prevent the patient's digestive esophagus from being damaged when entering the patient's digestive esophagus, and the adsorption sponge can absorb sputum when the sleeve 1 enters the esophagus.

[0035] In summary: when the foreign body removal sleeve of the digestive endoscope is used to remove the iron nail foreign body, after the sleeve 1 reaches the position of the foreign body in the patient's esophagus, the iron nail is clamped through the removal component 9, and the inflation port 802 is connected to the first connection port 403, and the small motor 801 works, and then the gas generated by the small motor 801 passes through the first trachea 402 and the first mounting member 401 to inflate the expansion balloon 3, so that the expansion balloon 3 is inflated to a suitable degree. At this time, the operating space of the removal component 9 will become larger, and then the medical staff controls the operating handle 903 to make the forceps head 902 clamp the iron nail, and then bring the iron nail into the interior of the sleeve 1 through the operating handle 903. At this time, the inflation port 802 is connected to the first connection port 403, and the small motor 801 works, and then the gas generated by the small motor 801 passes through the first trachea 402 and the first mounting member 401 to inflate the expansion balloon 3. The air port 802 will be connected to the second connecting port 603, and the small motor 801 will work. The gas generated by the small motor 801 will enter the interior of the closed airbag 5 through the second air pipe 602 and the second mounting member 601, so that the closed airbag 5 is expanded to an appropriate degree. At this time, the closed airbag 5 can close the port 2, and at the same time, the iron nail foreign body clamped by the operating handle 903 will be adsorbed on the magnetic block 701, and then when the port 2 is taken out, the iron nail is adsorbed on the magnetic block 701, and at the same time, the port 2 is closed. If the operating handle 903 is loose, the iron nail will not fall to the outside, so that when the iron nail is removed, the sharp part of the iron nail will not cause scratches to the patient.
