Anastomotic stoma leakage after rectal cancer surgery is a serious complication in colorectal surgery. Once it occurs, it will cause intestinal contents to leak into the abdomen, seriously affecting the health of patients, often leading to serious complications such as peritonitis, septic shock, and multiple organ dysfunction, and in more severe cases, it will cause the death of patients. Therefore, the research and application of anastomotic stoma leakage prevention devices are of great significance for improving the prognosis and quality of life of patients undergoing rectal cancer surgery.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 7 shown, the present invention provides an anastomotic leakage prevention device for rectal cancer after surgery, including a leakage prevention component 6, and further including: An intestinal body 7, with an anastomosis 8 sutured in the middle of the intestinal body 7. The leakage prevention component 6 is located inside the intestinal body 7 and is used to block and support the anastomosis 8. Among them, the leakage prevention component 6 includes a leakage prevention sleeve film 61. A pair of support airbag components 62 are arranged in the middle of the leakage prevention sleeve film 61. Fixed airbag components 63 and discharge ports 64 are respectively arranged at both ends of the leakage prevention sleeve film 61. Three groups of air inlet ports 65 are arranged in the middle of the leakage prevention sleeve film 61, and the three groups of air inlet ports 65 correspond to the positions of the fixed airbag components 63 and a pair of support airbag components 62 respectively.

[0020] Adopting the above solution: By pulling the internal extrusion block 5 along the support column 1 towards the excretion port of the intestinal body 7 through the limit housing 4, the extrusion block 5 squeezes the air supply airbag 2 to contract, so that the gas inside the air supply airbag 2 is transported through the air supply hose 3 and the air inlet port 65 into the fixed support airbag 631, causing the fixed support airbag 631 to inflate and expand. At the same time, when the extrusion block 5 moves past the air supply hose 3, the extrusion block 5 will squeeze and pull the air supply hose 3, disconnecting the air supply hose 3 from the air inlet port 65. After inflation is completed, the support column 1 can be withdrawn to complete the installation of the leakage prevention component 6.

[0021] As Figures 1 to 4 shown, the leakage prevention sleeve film 61 has a gradually converging horn-shaped structure. The fixed airbag component 63 is located at the end with a larger opening of the leakage prevention sleeve film 61, and the discharge port 64 is located at the end with a smaller opening of the leakage prevention sleeve film 61, and the discharge port 64 is located at one end of the excretion port of the intestinal body 7.

[0022] Adopting the above solution: By setting the leakage prevention sleeve film 61 to a horn shape, it is convenient to adapt to the intestinal body. By arranging the discharge port 64 at one end of the excretion port of the intestinal body 7, it is convenient to discharge the contents of the intestinal body, and the leakage prevention sleeve film 61 blocks to prevent the contents from contacting the anastomosis 8.

[0023] As Figures 2 to 5As shown in the figure, the support airbag component 62 includes a limit airbag ring 621 fixedly connected to the outer side of the leak-proof sleeve film 61 and an airbag support ring 622 fixedly connected to the inside of the leak-proof sleeve film 61. An inwardly retractable film 623 is provided in the middle of the leak-proof sleeve film 61. A first airbag channel 624 is annularly distributed between the limit airbag ring 621 and the airbag support ring 622. Two groups of strip-shaped support airbags 625 are annularly distributed in the middle of the inwardly retractable film 623. The limit airbag ring 621 is distributed on both sides of the inwardly retractable film 623. The airbag support ring 622 is located at the connection between the inwardly retractable film 623 and the leak-proof sleeve film 61. The two groups of strip-shaped support airbags 625 are respectively communicated with the inwardly retractable film 623, and the strip-shaped support airbags 625 are staggeredly distributed. A pair of air injection ports 65 are provided inside the support airbag component 62. One air injection port 65 is provided inside the limit airbag ring 621 near the discharge port 64, and one air injection port 65 is provided in the middle of the airbag support ring 622 near the fixed airbag component 63.

[0024] Adopting the above solution: By setting the support airbag component 62, the limit airbag ring 621 and the airbag support ring 622 are used for support and limitation, so that the anastomosis 8 is kept in the middle of the limit airbag ring 621. At the same time, the setting of the inwardly retractable film 623 can make the inwardly retractable film 623 tighten inward when the anastomosis 8 is bent, avoiding squeezing the anastomosis 8. By setting the inwardly retractable film 623, it is convenient to connect the limit airbag ring 621 and the airbag support ring 622 for inflation. After the strip-shaped support airbags 625 distributed in a staggered manner are inflated, they play a role of a framework to support the inwardly retractable film 623, making the inwardly retractable film 623 in an open state without tightening. At the same time, it avoids the contents inside the intestinal body 7 squeezing the anastomosis 8 when passing through the inwardly retractable film 623. The setting of the air injection port 65 is used to inflate the inside of the support airbag component 62.

[0025] As Figure 2 、 Figure 3 and Figure 5 As shown in the figure, the fixed airbag component 63 includes a fixed support airbag 631. A second airbag channel 632 is annularly distributed at the bottom of the fixed support airbag 631. The bottom of the second airbag channel 632 is communicated with the limit airbag ring 621, and a middle partition film 633 is fixedly connected inside the limit airbag ring 621 communicated with the second airbag channel 632. The outside of the fixed support airbag 631 is a multi-layer annular structure. The fixed support airbag 631 abuts against the intestinal body 7. One air injection port 65 is provided inside the limit airbag ring 621 communicated with the second airbag channel 632.

[0026] Adopt the above solution: By setting the fixed airbag component 63 to support and fix the leak-proof sleeve film 61, the outer fixed support airbag 631 with a multi-layer annular structure can closely fit with the intestinal body to play a fixing role, and at the same time prevent the contents from passing outside the fixed support airbag 631. By setting the second airbag channel 632, the second airbag channel 632 also plays a role of a framework here, connecting the fixed support airbag 631 with the limit airbag ring 621. By connecting the limit airbag ring 621 and the fixed support airbag 631 to the intestinal body 7 at the same time and supporting each other, the fixing of the leak-proof sleeve film 61 becomes more stable.

[0027] As Figures 5 to 7 shown, a leak-proof component for the anastomotic stoma after rectal cancer surgery includes a limit housing 4. The leak-proof component 6 is installed in a compressed state inside the limit housing 4. A support column 1 is slidably connected to the inside of the limit housing 4. The support column 1 is located inside the leak-proof component 6. An air supply airbag 2 is fixedly connected inside the support column 1. Three air supply hoses 3 corresponding to the position of the air supply port 65 are arranged in the middle of the air supply airbag 2. The air supply hoses 3 penetrate the support column 1 and are connected to the air supply port 65. A pressing block 5 is fixedly connected to the inside of the limit housing 4. The pressing block 5 is slidably connected inside the support column 1 and abuts against the air supply hoses 3.

[0028] Adopt the above solution: By setting the limit housing 4, it is convenient to send the leak-proof component 6 into the intestinal body 7. The support column 1 plays a supporting role. When the limit housing 4 is pulled out, it supports and limits the leak-proof component 6. The setting of the air supply airbag 2 and the air supply hoses 3 can inflate the inside of the leak-proof component 6 that is released from compression while the limit housing 4 is pulled out, so that the leak-proof component 6 unfolds. By setting the pressing block 5, when the limit housing 4 moves, it pulls the pressing block 5 to squeeze the air supply airbag 2, so that the air supply airbag 2 inflates the inside of the leak-proof component 6.

[0029] The working principle and usage process of the present invention: When in use, insert the limit housing 4 deep into the intestinal body 7 and cross the anastomotic stoma 8, and then hold the support column 1 and pull the limit housing 4 outward at the same time. At this time, the leak-proof component 6 is released from compression at the fixed support airbag 631. At the same time, the limit housing 4 pulls the internal pressing block 5 to slide along the support column 1 towards the excretion port of the intestinal body 7, so that the pressing block 5 squeezes the air supply airbag 2 to contract, and the gas inside the air supply airbag 2 is transported through the air supply hoses 3 and the air supply port 65 into the inside of the fixed support airbag 631, so that the fixed support airbag 631 inflates and unfolds; Afterwards, the rear limiting housing 4 moves to the position of the supporting airbag component 62 to inflate the supporting airbag component 62, causing the supporting airbag component 62 to expand and unfold to support the inside of the intestinal body 7. At the same time, when the extrusion block 5 moves past the air delivery hose 3, the extrusion block 5 will squeeze and pull the air delivery hose 3 to disconnect the air delivery hose 3 from the air delivery port 65. After inflation is completed, the support column 1 can be withdrawn. At this time, the bottom of the discharge port 64 is located outside the intestinal body 7.
