Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a low rectal anastomosis protection device capable of draining feces. Background Technology

[0002] In rectal surgery, especially after resection of mid-to-low rectal cancer, anastomotic protection is crucial, as anastomotic leakage is one of the most common and serious complications, directly impacting patient prognosis and quality of life. To reduce the occurrence of anastomotic leakage, the traditional prophylactic ileostomy method is widely used. This method typically requires an additional incision in the patient's abdominal wall to create an ileostomy, forming an external defecation pathway. While this method effectively reduces the risk of anastomotic leakage, the resulting problems cannot be ignored.

[0003] First, ileostomy requires additional surgical procedures, increasing patient trauma and recovery time. Furthermore, patients need to wear an ostomy bag post-surgery. While modern ostomy bags are relatively convenient, they still cause considerable inconvenience to patients' daily lives. The ostomy bag needs regular changing and cleaning, which not only increases the difficulty of care but also imposes a significant financial burden. Patients often experience physical discomfort and psychological stress when facing these practical problems.

[0004] More importantly, the presence of an ileostomy can negatively impact a patient's mental health, affecting their quality of life and social activities. The combination of psychological stress and physical discomfort can easily exacerbate anxiety, leading to a greater psychological burden during postoperative recovery. Therefore, reducing the use of ileostomies or finding more comfortable and effective alternatives has become an important research direction in the medical field. Utility Model Content

[0005] The purpose of this invention is to provide a low-level rectal anastomosis protection device that can drain feces.

[0006] This utility model is achieved through the following technical solution: a low rectal anastomosis protection device capable of draining feces, which includes an airbag structure, a thin film drainage tube and an absorbable suture; the airbag structure includes an upper airbag and a lower airbag disposed on the outer periphery of the thin film drainage tube; wherein, the upper airbag is sleeved on the top of the thin film drainage tube, and the lower airbag is disposed below the upper airbag at intervals.

[0007] The absorbable suture is tied and fixed to the periphery of the rectal tissue, so that the rectal tissue and the membrane drainage tube are closely attached. The absorbable suture is tied and fixed between the upper and lower air balloons.

[0008] The membrane drainage tube is also equipped with an air injection structure. One end of the air injection structure is connected to the upper airbag and the lower airbag, and the air injection structure extends out of the membrane drainage tube.

[0009] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0010] This invention can directly drain feces from the proximal end of the intestine to the anus, while effectively isolating feces from the anastomosis, reducing the risk of postoperative anastomotic leakage, improving the success rate of surgery, and improving the patient's quality of life.

[0017] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0018] like Figures 1 to 4 As shown, a low rectal anastomosis protection device capable of draining feces includes an airbag structure 1, a thin film drainage tube 2, and an absorbable suture 3; the airbag structure 1 includes an upper airbag 11 and a lower airbag 12 disposed on the outer periphery of the thin film drainage tube 2; wherein, the upper airbag 11 is sleeved on the top end of the thin film drainage tube 2, and the lower airbag 12 is disposed at a distance below the upper airbag 11.

[0019] The absorbable suture 3 is tied and fixed to the periphery of the rectal tissue, so that the rectal tissue is closely attached to the membrane drainage tube 2. The absorbable suture 3 is tied and fixed between the upper airbag 11 and the lower airbag 12.

[0020] The membrane drainage tube 2 is also provided with an air injection structure. One end of the air injection structure is connected to the upper airbag 11 and the lower airbag 12, and the air injection structure extends out of the membrane drainage tube 2.

[0021] Furthermore, the air injection structure includes an air injection tube 4, the top end of which is connected to a diversion tube and communicates with the upper airbag 11 and the lower airbag 12 respectively. The other end of the air injection tube 4 extends into a thin film drainage tube 2 and is provided with an air injection port 41. Air is injected through the air injection port 41, and the gas passes through the air injection tube 4 and the diversion tube successively, thereby inflating the upper airbag 11 and the lower airbag 12 in the rectum, so that the upper airbag 11 and the lower airbag 12 are tightly attached to the inner wall of the rectum.

[0022] The tail end of the thin-film drainage tube 2 is provided with a drainage interface 21, which is used to connect with an external drainage bag or ostomy bag. This invention can directly drain feces from the proximal end of the intestine out of the anus, while effectively isolating feces from the anastomosis, reducing the risk of postoperative anastomotic leakage, improving the success rate of surgery, and improving the patient's quality of life.

[0023] How to use:

[0024] After the ileostomy, the end of the membrane drainage tube 2 with the balloon structure 1 is inserted into the rectum. At this time, the balloon structure is not inflated and the upper balloon 11 and the lower balloon 12 have both crossed the position of the anastomosis line. Then, the balloon structure 1 is inflated through the air inflation tube 4, so that the upper balloon 11 and the lower balloon 12 bulge and stick to the inner wall of the rectum.

[0025] After confirming that the position is correct, gently tie and knot the absorbable suture 3 around the outside of the intestine to fix the position of the membrane drainage tube 2. Then, remove the tail end of the membrane drainage tube 2 out of the rectum and connect it to the drainage bag.

[0026] It should be noted that after the anastomosis has healed well, the airbag structure 1 can be deflated one week after the operation. After the upper airbag 11 and the lower airbag 12 have both retracted, the present invention can be directly removed from the rectum.

[0027] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
