A wrapper tube of capsule inner mirror oesophagus examination assistance machine

Abstract

The invention relates to the medical instrument technical field, which is the external casing of a capsule endoscope esophagus inspection auxiliary. The external casing consists of two parts of a double-cavity pipe (1) and a mouth gasket (2), the double-cavity pipe is a slender pipe, the one is the wire-draw pipe cavity of the capsule endoscope esophagus inspection auxiliary, the other one is a biopsy forceps pipe cavity, one end of the double-cavity pipe is bent presenting an arc shape and being connected with the mouth gasket; the mouth gasket is coarse and short, and is integrated with the double-cavity pipe as a whole, two pipe cavities of the double-cavity pipe penetrate the mouth gasket, a pipe mouth (23) is arranged at the liberation end of the mouth gasket, a ring type edge (21) is arranged at one end of the mouth gasket adjacent to the double-cavity pipe, and a mouth gasket cover (22) is arranged at the liberation end. The structure of the invention is simple, the operation is convenient, a throat mucous membrane or an esophagus mucous membrane safe from a wire-draw frictional damage of the auxiliary is effectively protected during the process of performing the capsule endoscope esophagus inspection, and the biopsy forceps can be inserted to acquaint a living tissue, thereby ensuring that the biopsy changes easy, and the pain of a patient is lightened.

Description

technical field [0001] The invention relates to the technical field of medical devices, and relates to an overtube of a capsule endoscopic esophagus inspection aid. Background technique [0002] There are about 130 million people who are positive for hepatitis B surface antigen in my country, more than 30 million people with chronic hepatitis B, and as many as 270,000 people die of hepatitis B-related liver diseases every year. Some patients with chronic hepatitis B will develop liver cirrhosis and portal hypertension, and bleeding from esophageal varices is one of the main causes of death in such patients. Esophageal cancer is also a common disease in my country, and nearly 200,000 patients die of esophageal cancer every year. Gastroesophageal reflux disease and Barrett's esophagus are also common diseases in my country. The former seriously affects people's quality of life, and the latter is more than 10 times more likely to develop esophageal adenocarcinoma than normal p...

Problems solved by technology

Although the use of this auxiliary device can save resources, reduce the cost of use, reduce the pain of patients, and avoid cross-infection, repeated pulling during the inspection, and the friction of the lifting thread on the mucous membrane of the throat will cause local damage and discomfort. In addition, even if the lesion is observed, it cannot For biopsy, it is necessary to obtain pathological tissue with conventional gastroscopy, which limits its further application
