[0051] Further, as shown in the drawings, Figure 5 the outer wall of the end of the inner core 2 extending into the stomach is provided with a plurality of suction holes 21.

[0052] It should be noted that in the process of sucking out the blood clots or food residues in the stomach, the blood clots or food residues may block the end hole of the inner core 2. By arranging the plurality of suction holes 21, the risk of the inner core 2 being completely blocked is reduced.

[0053] Further, as shown in the drawings, Figure 5 the outer wall of the inner core 2 is provided with a sealing portion 22 near the connecting head 23, one end of the outer sleeve 1 is sleeved at the sealing portion 22, and the sealing portion 22 is used for sealing the one end of the outer sleeve 1.

[0054] As can be understood, as shown in the drawings, Figure 1 after the outer sleeve 1 is sleeved on the inner core 2, the upper end of the outer sleeve 1 is clamped at the sealing portion 22, so that the upper end of the outer sleeve 1 is sealed, avoiding air leakage during operation or leakage of food residues or blood in the stomach from the outer sleeve 1. As shown in the drawings, Figure 5 the sealing portion 22 can be a plurality of annular retaining rings arranged on the outer wall of the inner core 2.

[0055] Further, as shown in the drawings, Figure 6 the outer wall of the inner core 2 is provided with a control hole near the connecting head 23, a control tube 24 is arranged on the control hole, one end of the control tube 24 is sealingly connected with the control hole and communicates with the inside of the inner core 2, the other end of the control tube 24 is an opening, and a sealing plug 241 is connected on the control tube 24 and used for sealing the opening.

[0056] As can be understood, by arranging the control hole, the opening of the control tube 24 can be sealed by the sealing plug 241, so that the inner core 2 can be sucked, and physiological saline or air can be quickly injected into the inner core 2 through the control tube 24, solving the problem of pipe blockage of the inner core 2.

[0057] Since the elastic modulus of the elastic ring 3 is large, it is relatively laborious to directly use hands to sleeve the elastic ring 3, therefore, as shown in the drawings, Figure 7As shown, the utility model provides a kind of auxiliary device, including taper head 4, the tail portion of taper head 4 is provided with sleeve 41, the outer diameter of sleeve 41 is greater than the sum of the diameter of gastroscope 5 and the thickness of connecting piece 11, sleeve 41 is used to be sleeved in connecting piece 11 and gastroscope 5 outside, the outer diameter of the tail portion of taper head 4 is greater than the outer diameter of sleeve, and taper head 4 is used to guide elastic ring 3 to be sleeved into sleeve 41.Taper head 4 can adopt metal material, and can be repeatedly used.

[0058] It can be understood that, as Figure 9 As shown, after connecting piece 11 of outer sleeve 1 is attached with the first end portion of gastroscope 5, sleeve 41 is sleeved outside connecting piece 11 and gastroscope 5, and elastic ring 3 is moved downwards along taper head 4, so that elastic ring 3 is sleeved on sleeve 41, at this time, taper head 4 and sleeve 41 are extracted, and elastic ring 3 can be exactly sleeved outside connecting piece 11 and gastroscope 5.

[0059] Further, as Figure 7 As shown, taper head 4 is a hollow structure, and limiting ring 42 is arranged at the tail portion of taper head 4, and limiting ring 42 is used to limit the first end portion of gastroscope 5 to be inserted into taper head 4. Figure 9 As shown, when elastic ring 3 is moved downwards along taper head 4, gastroscope 5 can be abutted on limiting ring 42

[0060] Further, the length of sleeve 41 is less than the length of elastic ring 3, so that the friction between sleeve 41 and elastic ring 3 can be reduced, and taper head 4 and sleeve 41 are facilitated to be extracted.

[0061] The use method of the double-layer channel suction tube includes:

[0062] After connecting piece 11 of outer sleeve 1 is attached with the first end portion of gastroscope 5, sleeve 41 of taper head 4 is sleeved outside connecting piece 11 and gastroscope 5, and elastic ring 3 is moved downwards along taper head 4, so that elastic ring 3 is sleeved on sleeve 41, taper head 4 and sleeve 41 are extracted, and elastic ring 3 is exactly sleeved outside connecting piece 11 and gastroscope 5, and the connection of outer sleeve 1 and gastroscope 5 is completed; after gastroscope 5 and outer sleeve 1 are sent to the bleeding site, inner core 2 can reach the visual field range along outer sleeve 1.For upper gastrointestinal tract massive hemorrhage patients, gastroscope 5 channel and inner core 2 can be used to realize double-channel suction of blood clots or stomach contents, and gastroscope 5 can also be used for timely treatment; for foreign matter that cannot be smoothly taken in the stomach cavity, the foreign matter can be sucked into inner core 2.During operation, the difficulty of endoscopy is not affected, and endoscopic operation is not affected.Both outer sleeve 1 and elastic ring 3 can be used as disposable consumables.
