Problems solved by technology

The general hard plastic transparent cap is installed on the front end of the endoscope. Turn the operating knob under the endoscope to make the front end of the endoscope bend laterally at a certain angle, expose the target vein, and find out the puncture point before the injection needle is extended, and then perform puncture injection. The treatment is time-consuming and the error rate is high.

Embodiment Construction

[0025] According to the position of the endoscopic biopsy hole and the puncture direction of the injection needle, on the basis of sufficient investigation and research, the present invention designs a transparent cap for esophageal varices sclerosing agent injection under the endoscope. It is significantly different from the transparent caps used in other endoscopic treatments: the present invention provides a transparent cap for injection of sclerosing agent for esophageal varices under endoscope, which includes a transparent cap The shell 1 is made of non-toxic transparent soft silicone material. A venipuncture window 3 is designed on the front end of the transparent cap shell 1. Before the transparent cap is installed in vitro, an injection needle is inserted into the biopsy hole, and the transparent cap is rotated to make the venipuncture window Consistent with the insertion direction of the injection needle. During treatment, it is only necessary to rotate the endoscope ...

Abstract

The invention relates to a transparent cap for injecting an esophageal vein sclerosing agent under an endoscope. The transparent cap for injecting the esophageal vein sclerosing agent under the endoscope comprises a transparent cap shell and a vein puncture window arranged at the end of the transparent cap shell. The transparent cap for injecting the esophageal vein sclerosing agent under the endoscope can improve the accuracy and the treatment success rate of endoscope treatment operation and reduce the probability of endoscope treatment errors, is simple in structure, economic, practical and convenient to operate and can be used safely.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a transparent cap for injection of esophageal varices sclerosing agent under endoscope. Background technique [0002] Esophageal variceal bleeding is one of the common causes of death in patients with various types of portal hypertension. Endoscopic variceal injection of sclerosing agent is one of the commonly used methods in the first-line treatment of this type of bleeding. Since Swedish doctors Crafoord and Frenekuer carried out the first endoscopic sclerosing agent injection treatment of esophageal varices in 1936, it has been 75 years since then. year history. Sclerotherapy has a very good effect in emergency hemostasis, and the emergency hemostasis rate is about 74% to 92%. According to controlled studies, it is better than three-chamber two-capsule tube compression therapy and simple drug therapy. Repeated sclerotherapy has a significant effect on preventing rebleed...
