Description

Abdomen implantation type colorectal anastomotic stoma protection device

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to an abdominal implantation type colorectal anastomotic stoma protection device.

Background

Common malignant tumors in the gastrointestinal tract of colorectal cancer (cancer of colon and rectum) have unobvious early symptoms, and show symptoms such as defecation habit change, hematochezia, diarrhea and constipation alternation, local abdominal pain and the like along with the increase of cancer, and show general symptoms such as anemia, weight loss and the like at late stage. The incidence and fatality rate of the cancer are only second to those of gastric cancer, esophageal cancer and primary liver cancer in digestive system malignant tumors. Surgical resection is the most effective treatment for colorectal cancer. However, anastomotic fistula is a common clinical complication, and the incidence rate of anastomotic fistula in the early stage is about 20% in China, and is reduced to about 5% with the continuous improvement of medical technology. The anastomotic fistula is difficult to treat, and the intestinal contents are led out in advance by conventionally adopting colon or terminal ileum fistulization so that the intestinal contents do not pass through an anastomotic stoma to prevent the anastomotic fistula so as to fulfill the aim of preventing or reducing the anastomotic fistula. However, the method also increases the operation trauma, reduces the life quality of patients, needs secondary operation to return the intestinal canal, and correspondingly increases the complication rate.

The utility model patent document with application number 201520831301.9, as shown in fig. 6, discloses a double-balloon intestinal fistulization catheter for preventing anastomotic fistula after colorectal surgery, comprising a catheter tube body, a first balloon, a second balloon, a thread pressing sheet, a first water filling port and a second water filling port; the catheter tube body is of a hollow tube body structure, and the two ends of the catheter tube body are respectively a head end and a tail end; the first balloon and the second balloon are two hollow balloons which are sleeved outside the catheter tube body and made of elastic materials; wherein the first balloon is adjacent to the head end; the second balloon is positioned between the first balloon and the tail end; the thread pressing sheet is sleeved on the catheter tube between the second balloon and the tail end in a thread engagement mode; a side hole is arranged on the tube wall of the catheter tube body between the first balloon and the head end; the first water filling port and the second water filling port are positioned at the tail end of the catheter body; the first water injection port is connected and communicated with the first balloon through a first communicating pipe; the second water injection port is connected and communicated with the second balloon through a second communicating pipe. The catheter is characterized in that the balloon realizes catheter positioning through one balloon and a threaded pressing sheet, the other balloon realizes intestinal content blocking, and the intestinal content is discharged through the catheter, so that the intestinal content is easy to leak by a single balloon, and the blocking effect is not ideal.
