[0029] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Reference Figures 1 to 4For the embodiment of the utility model, including: pipe body 1, be equipped with first channel 2 in the pipe body 1, one end of pipe body 1 is equipped with the first opening 3 that communicates with first channel 2, first air bag 4, first air bag 4 is located in the pipe body 1, when the anal tube is placed in rectum, first air bag 4 is located in rectum, second air bag 5, second air bag 5 is located in the pipe body 1, when the anal tube is placed in rectum, second air bag 5 is located outside the anus, inflation assembly, the inflation assembly communicates with first air bag 4, second air bag 5, front inclined hole 6, front inclined hole 6 is located in pipe body 1, and is located in the side of first air bag 4 away from second air bag 5, front inclined hole 6 communicates with first channel 2, the first opening 3 is located in the side of second air bag 5 away from first air bag 4.

[0031] Specifically, pipe body 1 can be prism or cylindrical, and the embodiment is preferably cylindrical, which can reduce the angle and avoid causing pain to the patient when inserted into the rectum. The material of pipe body 1 is soft and harmless to the human body, and in the embodiment, it is preferably silicone. First air bag 4 and second air bag 5 are both round cake-shaped with a round side, and are coaxially arranged on pipe body 1. The material of first air bag 4 and second air bag 5 is also silicone.

[0032] Before the end of the rectal or anal tube surgery, pipe body 1 is placed into the rectum through the anus, and then first air bag 4 is inflated by using the inflation assembly. First air bag 4 inflates and expands in the rectum, achieving the effect of appropriate compression and expansion of the surgical wound or anastomotic stoma, while preventing bleeding and anastomotic stoma stenosis. When first air bag 4 reaches the appropriate size, second air bag 5 is inflated. After second air bag 5 is inflated, it can block at the anus, cooperating with first air bag 4, to relatively fix pipe body 1 at the current position, preventing pipe body 1 from moving in the anus. Compared with the prior art, the present application does not need to fix pipe body 1 at the anus by skin suturing, avoiding secondary harm to the patient after surgery. At the same time, the setting of front inclined hole 6 also facilitates subsequent operations of filling contrast medium, cleaning liquid, etc. into the rectum.

[0033] In the embodiment, second opening 7 is arranged on pipe body 1, second channel 8 is arranged in pipe body 1, and second opening 7 communicates with first opening 3 through second channel 8. When pipe body 1 is inserted into the rectum, second opening 7 is located in the rectum.

[0034] Specifically, first opening 3 and second opening 7 are respectively located at both ends of the length direction of pipe body 1, i.e. second opening 7 and first opening 3 are respectively located on the two axial end faces of pipe body 1. The aperture of second opening 7 is larger than that of front inclined hole 6, and smaller than the diameter of pipe body 1, so that the patient can exhaust, defecate and enema through second opening 7, second channel 8 and first opening 3.

[0035] In this embodiment, the portion of the tube body 1 surrounding the second opening 7 is a smoothly curved surface. Specifically, because the aperture of the second opening 7 is smaller than the diameter of the tube body 1, a transition portion 9 is formed between the sidewall of the tube body 1 and the second opening 7. This transition portion 9 is a circular arc, thereby preventing the portion of the tube body 1 inserted into the rectum from having sharp corners that could cause harm to the patient.

[0036] In this embodiment, there are a plurality of forward-inclined holes 6 , and the plurality of forward-inclined holes 6 are symmetrically distributed on the tube body 1 with the axis of the tube body 1 as the axis of symmetry.

[0037] Specifically, the number of forward-tilting holes 6 can be any even number. In this embodiment, the number of forward-tilting holes 6 is two. The two forward-tilting holes 6 are connected to the first opening 3 through a first channel 2 respectively, and the two first channels 2 are not connected to each other, so that the operator can inject liquid that does not pass through the two first channels 2 respectively to meet a variety of practical needs.

[0038] In this embodiment, the diameter of the forward-leaning hole 6 is 8 mm.

[0039] In this embodiment, a third channel 10 and a fourth channel 11 are provided in the tube body 1 ; the first airbag 4 is connected to the inflatable component through the third channel 10 ; the second airbag 5 is connected to the inflatable component through the fourth channel 11 .

[0040] Specifically, the first channel 2, third channel 10, and fourth channel 11 are all formed by arc-shaped partitions made of the same material as the tube body 1 and the inner wall of the tube body 1. The second channel 8 is formed by the remaining space within the tube body 1, thereby achieving the effect of not communicating with each other. The tube body 1 also has air holes 12, which are located in the first airbag 4 and the second airbag 5. The air holes 12 in the first airbag 4 communicate with the third channel 10, and the air holes 12 in the second airbag 5 communicate with the fourth channel 11, allowing air to be inflated into the first airbag 4 and the second airbag 5 through the third channel 10 and the fourth channel 11.

[0041] In this embodiment, the inflation component includes a first inflation tube 13 and a second inflation tube 14; the first inflation tube 13 is connected to the third channel 10; the second inflation tube 14 is connected to the fourth channel 11; the first inflation tube 13 is provided with a first switch valve 15; the second inflation tube 14 is provided with a second switch valve 16.

[0042] Specifically, the first and second inflation tubes 13, 14 are both disposed through the tube body 1 and communicate with the third and fourth passages 10, 11, respectively. To inflate the airbag, the first on-off valve 15 is first opened. An external inflation device, such as an air pump or a pump, is then used to pump air into the first inflation tube 13. When the first airbag 4 is inflated to the desired size, the first on-off valve 15 is closed. The second on-off valve 16 is then opened, and air is pumped into the second inflation tube 14 using an external inflation device. When the second airbag 5 is inflated to the desired size, the second on-off valve 16 is closed.

[0043] In this embodiment, the axial width of the first airbag 4 after inflation does not exceed 5 cm. If the first airbag 4 is too large, it will cause excessive compression on the patient's rectum, causing adverse consequences. If the first airbag 4 is too small, it will not be able to exert appropriate compression on the patient's rectum.

[0044] In this embodiment, the distance between the first airbag 4 and the second airbag 5 is 2 to 3 cm. If the distance between the first airbag 4 and the second airbag 5 is too large, it will be difficult to fix the tube body 1 in the patient's rectum, and the tube body 1 may easily slip. If the distance between the first airbag 4 and the second airbag 5 is too small, it will be difficult to fully expose the second airbag 5 outside the anus.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
