Endoscopic hemostatic cannula

Abstract

The invention provides an endoscopic hemostatic cannula, comprising a hollow hose. a first annular sac chamber is sleeved at the distal end of the hose; a first pipe is arranged along the axial direction of the hose; the first annular sac chamber is communicated with the first pipe; fluid can be injected into the first annular sac chamber through the first pipe; and a plurality of operation windows are arranged close to the side walls of the hose of the annular sac chamber; The endoscopic hemostatic cannula is inflated by injecting a fluid into the annular capsule chamber to achieve hemostasis. The sclerosant injection hemostasis operation can be performed through a window opened on the side wall of the hose close to the annular capsule chamber, so that the whole operation can be completedat one time without moving the endoscopic hemostatic cannula, which is more efficient than the existing technical scheme and has better therapeutic effect.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical endoscopic hemostatic sleeve. Background technique [0002] With the development of endoscopic treatment, more and more hospitals have carried out sclerotherapy of esophageal varices, the purpose is to occlude the veins of esophageal varices through sclerosing agents, and treat and prevent esophageal venous bleeding. The specific method is: insert the gastroscope into the hemostatic sleeve of the gastroscope, and inject the sclerosing agent into the varicose vein through a special injection needle under the direct vision of the gastroscope. The sclerosing agent coagulates rapidly in the blood vessel, stimulates the blood vessel to produce inflammation, and finally hardens, so as to achieve the purpose of occluding the blood vessel. Under normal circumstances, the sclerosing agent injected into the vein flows with the blood, causing the drug concentration at the treatment site to dro...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned scheme preliminarily solved the technical problem that the concentration of the drug decreased rapidly with the blood flow, but the effect was not ideal. During the operation, it was necessary to first inflate the airbag to compress the bleeding point to stop bleeding, then remove the airbag, and then inject sclerosing agent to stop the bleeding; During the process of injecting sclerosing agent by opening the balloon, the bleeding point may bleed again, causing the blood to flow rapidly, causing the drug to decrease with the blood loss and reduce the drug concentration, reducing the therapeutic effect
