Compression hemostat applied to esophagus and fundus ventriculi

Abstract

The invention discloses a compression hemostat applied to esophagus and fundus ventriculi. The compression hemostat comprises a stent which can expand and is provided with a channel in the middle, and a bleeding arresting dressing fixed on the outer side of the stent. When massive hemorrhage caused by varicose veins of esophagus and fundus ventriculi occurs, the compression hemostat is placed at a bleeding position by using a stent inserter for arresting bleeding, and the bleeding arresting dressing is closely contacted with the bleeding position under the compression action of the expanding stent, so that the aim of arresting bleeding is fulfilled. The invention has the beneficial effects that: the compression hemostat is easy to operate and is convenient to use, and massive hemorrhage of esophagus and fundus ventriculi can be controlled effectively.

Description

Technical field

[0001] The invention relates to a medical device, in particular to a compression hemostatic device used for the esophagus and the fundus of the stomach. Background technique

[0002] Liver cirrhosis and portal hypertension are common and frequently-occurring diseases that seriously affect people’s health. Rupture and bleeding of esophagus and gastric varices is one of its most serious complications. Its first bleeding mortality rate is as high as 50%, and the incidence of repeated bleeding 80%, how to effectively control major bleeding is an urgent problem to be solved. In the past, surgical treatment was mostly used for the disease. Due to the large surgical trauma, strict indications, postoperative complications and other reasons, currently, emergency surgical treatment is not recommended. In the past 20 years, endoscopic sclerosing agent injection therapy and endoscopic band ligation therapy have been used, but due to high surgical requirements. The high risk...

Embodiment 2

[0024] The structure of this embodiment is image 3 Shown is a compression hemostatic device used when bleeding from the esophagus and stomach fundus. This embodiment is composed of a stent 1, a hemostatic dressing 3 outside the stent 1, and a hemostatic dressing fixing thread 4 for fixing the hemostatic dressing. One end of the bracket is cylindrical, and the other end is umbrella-shaped. It can support the esophagus and the fundus of the stomach. The other structure and usage are basically the same as in Example 1.

Embodiment 3

[0026] The structure of this embodiment is Figure 4 Shown. The stent 1 of this embodiment is made of an airbag. The shape of the air sac is a small pear-shaped upper part and a lower part, which can be used for hemostasis of the esophagus and the fundus of the stomach. The hemostatic dressing 3 is adhered to the outside of the airbag. When in use, after the stent made of the airbag is placed in the hemostatic site, the airbag is inflated to inflate the airbag, and the hemostatic site is compressed by the hemostatic dressing to achieve the purpose of hemostasis. After hemostasis is completed, the airbag is deflated, the airbag and the hemostatic dressing are separated, the airbag is taken out of the body, and the hemostatic dressing can be absorbed or discharged from the body by itself.
