Description

Anorectal cannula

Technical Field

The utility model relates to an enteroscopy and treatment field, concretely relates to anorectal cannula.

Background

The electronic colonoscope is a flexible tube which is about 140 cm long and can be bent, the tail end of the flexible tube is connected with a light source, and the tip of the flexible tube is provided with a miniature camera, and the electronic colonoscope is mainly used for detecting pathological changes of ulcers, polyps, tumors and the like in the large intestine. Tissue is taken for inspection or large intestine polyp is resected according to the condition. Colonoscopy is routinely performed by inserting the tube from the anus, gradually sheathing the tube on the colonoscope, inserting the tube along the intestinal lumen to the terminal of the ileum, and then withdrawing the colonoscope to observe the colons one by one to detect the lesions. Since the intestine normally contracts radially, usually "deflates", the enteroscope is inserted, usually by injecting air or water into the intestine at the front end, so that the intestinal wall at the front end is opened for easy entry of the enteroscope. In order to improve the detection rate of intestinal diseases and reduce the rate of missed diagnosis, when the endoscope is withdrawn for observation, gas injection is needed to ensure that the intestinal cavity is fully opened, a patient has the feeling of flatulence and excretion, the anal is tightened by utilizing sphincter contraction in a reflective mode, the frictional resistance between an enteroscope tube and the anus is increased, and the pain of the patient and the difficulty of operation and inspection are increased. In addition, for patients with relaxed sphincter or weakened contraction capacity, gas or liquid in the intestinal canal can escape in the process of examination, the intestinal cavity is not fully expanded, on one hand, the examination effect is influenced, and on the other hand, aerosol is formed by the liquid and the gas escaping from the intestinal cavity, so that environmental pollution is caused, and the harm is caused to medical workers and patients who are subsequently examined.

We have proposed application numbers: 201610672556.4, the practical clinical effect is not satisfactory, the main reason is that the product structure is unreasonable, so the application is proposed through repeated experiments and continuous thinking and improvement.
