Outer sleeve of gastroscope for therapy

Abstract

The invention discloses an outer sleeve of a gastroscope for therapy. The outer sleeve comprises an outer sleeve body, wherein the outer sleeve body is divided into a front end and a tail end, one side, close to the tail end, of the outer sleeve body is provided with an outer joint communicating with the side, a fixing ring sleeves the tail end, and a snapping opening is formed in the fixing ring.According to the outer sleeve of the gastroscope for therapy, through arranging the sleeve, acute foreign matters can be in the outer sleeve in an entire process during withdrawing and cannot fall off during withdrawing; due to a protective action of the outer sleeve, secondary injury to a gullet or stomach cannot be caused, and the damage to the front end of the endoscope cannot be caused; and the outer sleeve and the gastroscope are conveniently snapped, in case of repeated foreign matter withdrawing, the outer sleeve can be left in a gastric cavity or gullet cavity, operations can be completed by only enabling the gastroscope to enter the outer sleeve at a time, and the injury to a laryngeal part of pharynx of a sufferer caused by repeated intubation is avoided.

Description

technical field [0001] The invention relates to the field of medical auxiliary related products, in particular to a therapeutic gastroscope overtube. Background technique [0002] The current removal method for sharp foreign bodies (such as fish bones, chicken bones, hairpins, jujube stones, etc.) in the upper gastrointestinal tract (esophagus, stomach) is to simply enter the esophagus or stomach with a gastroscope, and then pass foreign body forceps, snares, and baskets outside the body. Wait for the tool to be sent to the esophagus or stomach through the biopsy channel of the gastroscope, and the foreign body is taken out with forceps or sleeves and taken out together with the gastroscope. But there is certain deficiency in prior art: [0003] 1. Due to the sharpness of the sharp foreign body, it is not easy to control the angle during the removal process. At the same time, the esophageal lumen is relatively narrow. The esophageal lumen has three physiological stenosis at...

Problems solved by technology

[0003] 1. Due to the sharpness of the sharp foreign body, it is not easy to control the angle during the removal process. At the same time, the esophageal lumen is relatively narrow. The esophageal lumen has three physiological stenosis at the same time. It is easy for the foreign body to pass through the esophagus. Tube wall damage, esophageal bleeding or possible perforation

[0004] 2. No matter which tool is used to remove the foreign body, the foreign body will fall off due to physiological stenosis of the esophagus during the process of passing through the esophagus, causing incarceration in the esophagus, resulting in secondary damage to the esophagus

[0005] 3. Due to the need to pull the foreign body, the sharp foreign body needs to withstand the front end of the gastroscope, which is easy to cause damage to the front end of the gastroscope.
