Device and system for detecting intestinal fistula, biliary fistula and pancreatic fistula

Abstract

The invention provides a device and system for detecting intestinal fistula, biliary fistula and pancreatic fistula after alimentary tract anastomosis reconstruction, and belongs to the technical field of medical apparatus and instruments. The device includes a drainage tube, a sensing chip and a signal processor; the front end of the drainage tube is located around the anastomotic stoma or near asurgical field so as to perform drainage on the liquid around the anastomotic stoma; the sensing chip is arranged on the front end of the drainage tube so as to make the liquid around the anastomoticstoma contact with the sensing chip; and the sensing chip reacts to generate an electric signal when intestinal fistula, biliary fistula and pancreatic fistula occur. The device can perform real-timedetection on the leakage of contents in alimentary tracts so as to achieve the early diagnosis of the intestinal fistula, the biliary fistula and the pancreatic fistula.

Description

Technical field [0001] This application relates to the technical field of medical devices, and in particular to a device and system for detecting intestinal fistula, bile fistula and pancreatic fistula after anastomosis and reconstruction of the digestive tract. Background technique [0002] Anastomosis refers to the anastomotic interface formed by restoring or rebuilding the continuity and integrity of the digestive tract after the continuity of the digestive tract is destroyed by surgery or trauma. When the physical continuity is restored, the two ends of the anastomosis pass through cell growth , Tissue repair and other processes to re-establish complete physiological continuity and integrity to achieve complete healing of the anastomosis. During this process, abnormal anastomotic healing and leakage of digestive tract contents due to any factors are called "anastomotic fistula". Clinically, anastomotic fistula can occur in any part and any form of digestive tract anastomosis...

AI Technical Summary

Problems solved by technology

Its shortcomings are: 1), the premise of the above-mentioned clinical manifestations is severe anastomotic leakage and a considerable amount of intestinal contents need to leak into the abdominal cavity; 2), in some cases, the intestinal contents are leaked due to precipitation , or cannot form a large enough liquid pool, or the drainage tube is blocked to drain the intestinal contents, resulting in false negative results, seriously affecting the doctor's judgment, and thus delaying treatment; 3) Micro anastomotic leakage cannot be detected in the early stage, Therefore, targeted non-surgical interventions can be made at an early stage, often leading to unavoidable reoperation

[0005] At present, the methods for diagnosing anastomotic leakage include imaging contrast detection, colonoscopy and surgical exploration. The disadvantages are: 1), the sensitivity is not strong, especially the small missed diagnosis rate is not enough, often only for larger anastomoses Good sensitivity of oral fistula; 2), invasive examination; 3), non-dynamic monitoring means, especially for patients with small leaks, a single examination cannot be diagnosed
