Technical Field
[0001] The utility model relates to the technical field of medical auxiliary products, in particular to an anal drainage device after colorectal cancer surgery. Background Art
[0002] Colorectal cancer is the third most common cancer in the world, accounting for about 10% of all cancer cases. It is also the second leading cause of cancer-related deaths worldwide. Colorectal cancer mainly affects the elderly, with most cases occurring in people aged 50 and above. Patients with colorectal cancer usually require surgical treatment. Surgery is one of the main ways to treat colorectal cancer. Doctors usually choose different surgical methods based on the patient's specific situation, including tumor resection, partial colorectal resection, total proctocolectomy, etc. After surgery, chemotherapy, radiotherapy and other treatments are generally required to prevent the recurrence and spread of cancer cells. The key to the success of colorectal cancer surgery lies in adequate preparation before surgery, fine operation during surgery, and comprehensive treatment and rehabilitation management after surgery. When undergoing surgical treatment, patients should actively cooperate with the doctor's treatment plan, strengthen postoperative rehabilitation exercises and diet conditioning to improve the success rate of surgery and quality of life.
[0003] In actual clinical practice, after colorectal cancer surgery, it is usually necessary to insert a drainage tube into the patient's anus to drain the gas, liquid, etc. in the patient's intestine, reduce the pressure in the patient's intestine, and avoid complications and intestinal fistulas. The existing drainage tube has no fixed part, and the drainage tube is easy to shift or fall off. The tail end of the drainage tube is usually simply tied with a plastic bag to collect gas, liquid, etc., and the drainage tube cannot be flushed and cleaned; the existing problem is that there is no drainage tube specifically for this disease period, and the existing ordinary drainage tube is not easy to fix. When doctors fix the drainage tube, they can generally only puncture the drainage tube and sew it around the patient's anus, but the drainage tube is easy to be punctured, and the gas and liquid in the patient's body are easy to flow out of the tube; when the weight of the plastic bag tied at the tail end of the drainage tube becomes large, it is easy to fall off, the fixation is not firm, and it is unhygienic; and when replacing the plastic bag, the drainage tube cannot be closed, and liquid often flows on the inner wall, which is inconvenient to replace.
[0004] Therefore, how to design an anal drainage device for colorectal cancer surgery that is suitable for use after surgery for patients with colorectal cancer, has a separate suture part, the tail end of the drainage tube is connected to a drainage bag for collecting gas and liquid, the drainage tube can be temporarily closed when the drainage bag is replaced, and the drainage tube can be flushed and cleaned, is a technical problem that has not yet been solved in the prior art.
