Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an electric control device for injecting gastric fundus varices tissue glue. Background Art

[0002] Gastric fundus varices refer to changes in the veins of the gastric fundus that are beaded, polyp-like, or mass-like. Gastric fundus varices are usually caused by portal hypertension. There are many communicating branches between the portal vein and the vena cava. When the portal vein is hypertensive, blood in the portal system will be retained in it. In order to allow it to flow back, the communicating branches will be opened in large numbers, which will form many collateral circulations. The most important collateral circulation is esophageal gastric fundus varices, followed by abdominal wall varicose veins, and the third is subrectal varicose veins.

[0003] For patients with gastric varices, a disposable endoscopic injection needle is used to inject iodized oil and tissue glue into the gastric varices for treatment. Figures 1 to 3 As shown, the disposable endoscopic injection needle 1 comprises an injection tube 11, an injection needle 12 is provided at the upper end of the injection tube 11, and an injection handle 13 is provided at the lower end.
