Instrument capable of preventing esophageal stenosis for ESD (endoscopic submucosal dissection) post-operation

Abstract

The invention discloses an instrument capable of preventing esophageal stenosis for ESD (endoscopic submucosal dissection) post-operation. The instrument is used for later period heal of esophagus cancer submucosal dissection and prevention of the esophageal stenosis. The instrument comprises three balloons, an inflation tube is arranged in each balloon, the three inflation tubes are not communicated each other, a through hole is formed in each inflation tube and communicated with the inflation tube and the corresponding balloon, the balloons are positioned on the upper portion, and the middleand the low portion of a chest to support a whole esophageal wall. The instrument is additionally provided with a drainage tube, a stomach tube and a duodenal tube, the drainage tube is used for leading out saliva, the stomach tube is used for sucking out gas or liquid in a gastrointestinal tract, and the duodenal tube is used for conveying nutrition to a patient. The instrument is simple in structure and applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for preventing esophageal contraction and stenosis in the late healing of esophageal cancer submucosal dissection. Background technique [0002] Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is a new treatment method that has emerged in recent years. Complete resection avoids the pain of open surgery and the removal of organs. [0003] Compared with laparotomy and previous endoscopic treatment methods such as EMR, ESD has the following advantages: 1. Small trauma; 2. Patients can receive multiple treatments for multiple parts; 3. Allow doctors to obtain complete histopathological specimens for analysis; 4. , For tumors with large area and irregular shape or with ulcers and scars, the resection rate is more than 96%, so as to reduce the probability of recurrence. This technology is very mature. For countries with a large incidence of d...

Of course, this narrow lesion will also be prevented by spraying or injecting hormones during the operation, but the effect is not very good, and it will still affect the patient's eating and drinking. For patients with scar constitution, the consequences will be It may be larger, so that the patient needs repeated incisions, metal stent expansion and other operations, which makes the patient miserable
