Abstract

The invention discloses an injection ligation endoscope for gastric polyps, and belongs to the technical field of the gastroenterology department. The endoscope comprises a handle, an outer tube sleeve, an endoscope head, an injection mechanism, an endoscope mechanism and a polyps ligation mechanism. A telescopic mechanism is arranged in the endoscope head. The injection mechanism comprises an injection assembly, a telescopic assembly and two bending degree adjusting assemblies. The injection assembly is installed in the endoscope head, the outer tube sleeve and the handle. The telescopic mechanism is arranged at the front end of the injection assembly. The two bending degree adjusting assemblies are sequentially arranged at the front portion of the injection assembly. Each bending degreeadjusting assembly comprises an adjusting keel and a driving part, wherein the driving part is installed in the handle, and the adjusting keel is installed at the front portion of the injection assembly and connected with the driving part. The direction of an injection needle can be adjusted through the bending degree adjusting assemblies, the injection needle can point at the bottom of the gastric polyps at different positions in front, and the injection liquid injecting accuracy during the endoscope ligation clinical operation is improved.

Description

technical field [0001] The invention relates to the technical field of gastroenterology, in particular to an injection ligation endoscope for gastric polyps. Background technique [0002] Endoscopic band ligation is a commonly used method for the treatment of gastric polyps, which mainly achieves the purpose of treatment by ligation of the roots of polyps to cause ischemic necrosis. The polyps fall off and form shallow ulcers within the first week after ligation. However, because only the innermost mucosal layer in the stomach wall can resist gastric acid, and in some polyps, not only the mucosal layer protrudes into the polyp bulge, resulting in wounds after polyps fall off. The submucosa will be exposed, unable to resist the corrosion of gastric acid, forming ulcers that are difficult to heal, and even causing the risk of gastric perforation. [0003] Therefore, there is a clinical need for an injection ligation endoscope for gastric polyps that can prevent the gastric wa...
