Visible sacculus sleeve for esophageal and gastric varices

Abstract

A visible sacculus sleeve for esophageal and gastric varices comprises a sleeve body, an inflation pipe I, an inflation connector I, an inflation connector II and an inflation pipe II, wherein one end of the sleeve body is connected with a handheld end, a treatment window is arranged at the other end of the sleeve body, a far-end sacculus is arranged on one side of the treatment window, a near-end sacculus is arranged on the other side of the treatment window, the inflation pipe I and the inflation pipe II are arranged on the two sides of the inner wall of the sleeve body respectively, one end of the inflation pipe I is connected with the far-end sacculus, the other end of the inflation pipe I is connected with the inflation connector I, one end of the inflation pipe II is connected with the near-end sacculus, and the other end of the inflation pipe II is connected with the inflation connector II. According to the visible sacculus sleeve, a bleeding point can be accurately pressed with the help of the sleeve body and one of the sacculi till bleeding is stopped under an endoscope, the other sacculus presses the wall of the oesophagus so that an oesophagus vein can be blocked, and the probability of ectopic embolism is lowered. According to the visible sacculus sleeve, doctors in most primary hospitals can conveniently master the tissue glue injection technology and the sclerosis injection technology, and safety is improved in an operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visual balloon sleeve for varicose veins of the esophagus and gastric fundus. Background technique [0002] Rupture and bleeding of esophageal and gastric varices[1] is an emergency and severe disease that threatens people's health, especially in my country. It has been reported that the mortality rate for the first bleeding is as high as 48%-62% (average 50%). For preventive treatment, the recurrent bleeding rate in the second year is as high as 70%. In recent years, endoscopic interventional therapy has greatly improved the success rate of treatment for esophageal variceal bleeding, prolonging the 5-year and 10-year survival rates of such patients. National 16 A retrospective survey of 1,079 hospitalized patients with esophageal and gastric variceal bleeding from January 2005 to January 2006 in 19 hospitals in different regions found that the success rate of hemostasis was 89.8% ...

AI Technical Summary

Problems solved by technology

The difficulty of the operation lies in the fact that the sclerosing agent coagulation lags behind during the injection, causing bleeding at the eye of the needle. Sometimes, when the needle tip has not penetrated into the vein, the injection deviation or even laceration of the vein may cause massive bleeding due to breathing, nausea, hiccups and other reasons.
