Intestinal fistula stent kit

Abstract

The invention discloses an intestinal fistula stent kit. The intestinal fistula stent kit comprises an in-intestine air bag rack, an intestine coating layer, a multi-cavity connecting tube, an intestinal juice recycling module and an air supply module. The intestinal fistula stent kit has the advantages that that the in-intestine air bag rack is placed in from a fistula orifice, the intestine coating layer is used to coat the position, corresponding to the in-intestine air bag rack, of the intestine, a drainage effect is increased greatly by allowing the in-intestine air bag rack to expand, thorough fistula orifice exclusion is achieved, digestive juice can normally pass the fistula orifice position while the cleanliness of the fistula orifice is guaranteed, curing time is provided for thefistula orifice, and treatment time is shortened; due to the fact that internal drainage is adopted, the loss of the digestive juice and nutritional substances is reduced to the maximum extent, patient homeostasis can be maintained favorably, and fistula orifice curing is benefited; in addition, the multi-cavity connecting tube can be conveniently fixed and limited on the skin, displacement or sliding is avoided, surgical operation is facilitated, the pain of patients is relieved effectively, medical treatment costs and resources are saved, and wide popularization and application is benefited.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intestinal fistula support set suitable for tubular fistula. Background technique [0002] Intestinal fistula refers to an abnormal channel between the intestine and other organs, or between the intestine and the abdominal cavity or outside the abdominal wall. The former is called internal fistula, and the latter is called external fistula. Intestinal fistula causes intestinal content to flow out of the intestinal cavity, causing a series of pathophysiological changes such as infection, fluid loss, malnutrition, and organ dysfunction. Intestinal fistula is one of the serious complications of abdominal surgery, which is caused by trauma, surgical injury, severe abdominal infection, chronic intestinal inflammation and tumor. [0003] The treatment of intestinal fistula has always been a difficult problem in gastrointestinal surgery. Infection has not been effective...

AI Technical Summary

Problems solved by technology

However, due to the large amount of physiological secretion of digestive juice (adults secrete more than 10L of digestive juice in 24 hours), silicone tubes are often used for drainage beside the fistula in clinical practice, but the drainage method is not effective, and the silicone tube may stimulate and oppress the adjacent intestinal wall. Affect intestinal peristalsis and intestinal wall blood supply, long-term indwelling may lead to new intestinal fistula (iatrogenic intestinal fistula) at the compression site; secondly, external drainage is currently used clinically, and a large amount of digestive juice and nutrients are lost leading to internal environment Disorder and malnutrition seriously affect the prognosis of patients. In short, the current clinical treatment for intestinal fistula has a long cycle, high cost and unsatisfactory curative effect
