Abstract

The invention provides a gastric cancer surgical instrument, which comprises a gastroscope and a laparoscope, wherein the gastroscope comprises a gastroscope illuminating lamp, a gastroscope indicatorand a gastroscope camera, the gastroscope illuminating lamp is used for illuminating a local area, the gastroscope indicator is provided with a point light source, and is used for prompting the position of a stomach tumor, the gastroscope camera is used for transmitting an image, and the laparoscope is used for observing stomach tumors. By arranging the gastroscope indicator, a point light sourceemitted by the gastroscope indicator can penetrate through the gastric wall from the inside of the stomach to form a clear bright spot on the serosa layer of the stomach, the bright spot can be clearly observed in the visual field of the laparoscope, and the point light source is selected to improve the penetrating power and the irradiation precision of light, so that the stomach cancer surgicalinstrument can improve the accuracy of prompting the position of the stomach tumor.

Description

technical field [0001] The invention relates to the field of medical device research, in particular to a gastric cancer surgical device. Background technique [0002] Gastric cancer is a common malignant tumor in China. The popularization of gastroscopy has enabled more and more gastric cancers to be detected at an early stage. If surgical resection can be performed early, the survival rate of patients can be greatly improved. Because the tumor started to grow from the inside of the stomach and the early tumor volume was small, there may only be tiny ulcers on the mucosal surface of the stomach, while there were no traces of lesions on the outermost serosa surface of the stomach. Therefore, the location of the tumor cannot be determined only under the laparoscopic view. Moreover, during laparoscopic surgery, doctors cannot feel the location of lesions in the stomach by touching them with their hands, making it difficult to accurately remove lesions under laparoscopy. The p...
