Detachable gastroscope cannula with inflatable airbag

Abstract

The invention belongs to the field of medical equipment and particularly relates to a medical tool, namely a detachable gastroscope cannula with an inflatable airbag, which performs gastroscopic examination and surgery according to the modern medicine. The detachable gastroscope cannula comprises an inner pipe and an outer pipe, wherein the length of the outer pipe is smaller than that of the inner pipe; the front end and the rear end of the inner pipe extend out of the outer pipe; the middle part of the inner pipe protrudes, the outer diameter of the middle protruding part of the inner pipe is greater than those of other pipe sections of the inner pipe, meanwhile, the outer diameter of the middle protruding part of the inner pipe is greater than the inner diameter of the outer pipe, and the outer diameters of the other parts except for the middle protruding part of the inner pipe are smaller than the inner diameter of the outer pipe; the middle protruding part of the inner pipe is sleeved with an inflatable rubber ring; the inflatable rubber ring is fixedly connected with the inner pipe; and the middle protruding part of the inner pipe and the inflatable rubber ring are tightly nested with the outer pipe. According to the detachable gastroscope cannula, the detection rate of an early gastric cancer is improved, the operation efficiency is improved and the postoperative complications are reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a medical tool for gastroscopy examination and operation in modern medicine, which is a detachable gastroscope sleeve tube with an inflatable air bag. Background technique [0002] Gastroscopy is not only a simple inspection method, but also a screening tool and main treatment method for early cancers of the upper gastrointestinal tract. [0003] The endoscope is an invasive inspection. Generally, the endoscope enters from the patient's mouth, passes through the esophagus and enters the stomach. The doctor pushes the endoscope body to move forward, and when the endoscope enters the body, adjusts the endoscope through the operating handle and the endoscope body. Endoscope position and angle. When the tube attached to the endoscope is too flexible, the endoscope cannot pass through the esophagus and into the stomach. In order to ensure that the endoscope and the con...

Problems solved by technology

However, in the actual operation process, due to patients with hiatal hernia, cardia relaxation, involuntary hiccups, etc., the stomach is still not well inflated after repeated gas injections.

This not only prolongs the operation time, increases the difficulty of operation, and increases postoperative complications, but more importantly, it is imposs...
