Description

Technical Field

[0001] The utility model relates to the medical field, in particular to an auxiliary structure for preventing and treating rectal anastomotic leakage. Background Art

[0002] Anastomotic leakage (AL) is a common complication of rectal cancer surgery and is difficult to treat. Beyond satisfying surgical and technical factors (absence of intestinal ischemia and severe anastomotic separation), it is crucial to ensure that the anastomotic stoma does not undergo excessive separation. Excessive separation can lead to visual healing through localized mucosal growth, but the sinus cavity lacks the intestinal muscular layer. This lack of contraction, resulting in increased local pressure from stool accumulation and subsequent rupture, which can lead to the re-formation of a sinus cavity and prolonged healing. To ensure proper healing of the AL, three key factors must be met: 1. Fecal material must not pass through the anastomotic stoma (Event A); 2. Appropriate support is provided near the anastomotic stoma to alleviate intestinal stenosis following fistula formation (Event B); and 3. Patient drainage is ensured near the anastomotic stoma (Event C).

[0003] From a clinical perspective, it's easy to understand that colostomies only address Event A (the clinically observed phenomenon of "leakage leading to stenosis," with 20% of AL patients experiencing localized stenosis that cannot be reduced); self-expanding stents partially address Event B (intense irritation, easy displacement, and inadequate coverage); and rectal tubes address Event C (although flushable, poor diversion, and localized pain from anal fixation, making nursing care difficult). Undeniably, these approaches are consistently unsatisfactory. Whether a single device / method can address all three of these issues simultaneously remains a mystery, with no designs or reports to date. Utility Model Content

[0004] The problem to be solved by the present invention is to provide a rectal AL auxiliary device to help treat such patients in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a rectal anastomosis leakage treatment auxiliary device, comprising a catheter, wherein the catheter is wrapped with a main balloon and a plastic air balloon, the catheter has a drainage channel, the drainage channel has an outlet, a first auxiliary tube, a second auxiliary tube and a third auxiliary tube extend into the drainage channel from the outlet, the first auxiliary tube and the second auxiliary tube are respectively connected to the main balloon and the plastic air balloon, the outlet of the third auxiliary tube crosses the plastic air balloon and extends between the main balloon and the plastic air balloon and passes through the wall of the catheter, the catheter is provided with a water diversion channel along the inner wall, one end of the water diversion channel is connected to a water pipe, and the other end of the water diversion channel passes through the outer wall of the catheter above the main balloon.

[0006] Furthermore, the main balloon and the plastic airbag respectively have a first inner cavity and a second inner cavity, the first auxiliary tube and the second auxiliary tube respectively have a first inflation channel and a second inflation channel, the first inflation channel and the second inflation channel respectively connect the first inner cavity and the second inner cavity, and the third auxiliary tube has an auxiliary channel.

[0007] Furthermore, the first auxiliary pipe, the second auxiliary pipe and the third auxiliary pipe are connected to the first joint, the second joint and the third joint respectively, and the third joint and the water pipe are connected to the water pump respectively.

[0008] Compared with the prior art, the present invention has the following beneficial effects: the present invention is inserted into the patient's rectum through the catheter, and the main airbag is inflated through the first auxiliary tube to block the intestinal cavity above the rectal anastomosis. The excrement passing through the rectum flows out along the tube cavity of the catheter without passing through the rectal anastomosis. The anastomosis is continuously flushed and drained through the third auxiliary tube to re-wash, further reducing a small amount of feces leaking through the first airbag and the intestinal wall. The plastic airbag has the function of supporting the intestinal wall of the anastomosis to prevent stenosis, and the side hole near the side of the plastic airbag mouth has the function of flushing and drainage. The plastic airbag is inflated and cooperated with the main balloon to fully divert feces from the rectal anastomosis to promote its healing.

[0009] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
