Description

Technical Field

[0001] The utility model relates to the technical field of anastomotic fistula prevention, in particular to a rectal anastomotic fistula prevention suction device. Background Art

[0002] As people's living standards improve, life expectancy increases, and medical standards advance, the incidence of rectal cancer is getting higher and higher, and more and more patients are receiving surgical treatment. After the rectal tumor is removed through surgery, the remaining intestine is connected, and the interface is the anastomosis. If there is a small damage at the intestinal connection, the stool will flow into the abdominal cavity or the space around the rectum through the small damage, which is called anastomotic failure. Anastomotic failure is a common complication after rectal cancer surgery. Once it occurs, the consequences are serious, it may lead to serious abdominal infection and even endanger life.

[0003] A Chinese patent with publication number CN219048977U discloses an intestinal anastomosis leakage-proof protective stent. The stent is a tubular segmented structure, including a first circular tube portion and a second circular tube portion movably connected along the axial direction. The outer diameter of the first circular tube portion is greater than the outer diameter of the second circular tube portion. The first circular tube portion is integrally woven by a first braided wire in a W-shaped braiding manner. The first circular tube portion is coated with an anti-slip film. The second circular tube portion includes a plurality of circular tube segments arranged along the axial direction. Adjacent circular tube segments are movably connected. Each circular tube segment is integrally woven by a second braided wire in a W-shaped braiding manner. The second circular tube portion is coated with a protective film.

[0004] The above patent can solve the corresponding technical problems, can fit tightly with the intestinal wall, and can effectively prevent the risk of the stent sliding down and shifting. However, the above intestinal anastomosis leakage-proof protection stent can only simply support the anastomosis during use, and cannot disinfect the intestinal anastomosis and attract and discharge pus, which makes the anastomosis prone to infection, which is not conducive to the patient's recovery.

[0028] Among them, there is a gap between the first airbag 2 and the second airbag 4, and the rectal anastomosis is located between the first airbag 2 and the second airbag 4. The first airbag 2 and the second airbag 4 can support the two ends of the rectal anastomosis and seal the rectal anastomosis to avoid exudate contamination of the rectal anastomosis. In addition, the first airbag 2 and the second airbag 4 support the rectum, which has good stability and is not easy to move.

[0029] Among them, the air inlet ends of the first trachea 3 and the second trachea 5 are both placed outside the drainage tube 1, and the air inlet ends of the first trachea 3 and the second trachea 5 are respectively fixedly connected with an air pressure display balloon 10. The air pressure display balloon 10 on the first trachea 3 and the first airbag 2 are in a connected state. By observing the expansion state of the air pressure display balloon 10, the expansion state of the first airbag 2 and the support use of the first airbag 2 can be reflected. Similarly, the air pressure display balloon 10 on the second trachea 5 is connected to the second airbag 4, which can reflect the expansion state of the second airbag 4.

[0034] The first airbag 2 and the second airbag 4 are both made of silicone, which increases the comfort of the contact support between the first airbag 2 and the second airbag 4 and the rectum.

[0035] Among them, one end of the drainage tube 1 extending into the rectum has a rounded edge structure, which is helpful for the insertion of the drainage tube 1 and increases the smoothness of the insertion of the drainage tube 1 into the rectum.

[0036] Among them, the drainage tube 1, the first trachea 3, the second trachea 5, the flushing tube 6 and the suction tube 7 are all hose structures, which are convenient for connection with external instruments and easy to operate.

[0037] Working principle: When in use, one end of the drainage tube 1 is inserted into the rectal anastomosis, so that the rectal anastomosis is located between the first airbag 2 and the second airbag 4, and then the first air tube 3 and the second air tube 5 are connected to the inflation device in sequence, so that the first airbag 2 and the second airbag 4 can support the two ends of the rectal anastomosis and seal the rectal anastomosis to avoid the rectal anastomosis site from being contaminated by exudate and causing rectal anastomotic fistula;

[0038] When the anastomosis needs to be disinfected and cleaned, disinfectant liquid is input into the rectal anastomosis through the flushing tube 6, and then the flushing liquid and pus at the anastomosis are extracted through the suction tube 7 connected to an external suction pump to avoid accumulation of infection at the anastomosis. During the operation, the flow valve 8 can detect the output flow of the suction tube 7 and the flushing tube 6.

[0039] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
