Abstract

The invention discloses a Raman gastroscope diagnostic unit. The Raman gastroscope diagnostic unit comprises a gastroscope imaging system and a Raman imaging system. The gastroscope imaging system comprises a light source and a flexible endoscope, wherein the flexible endoscope collects the image in the stomach by means of the brightness of the light source. The Raman imaging system can acquire Raman spectra of gastric tissue. During gastroscopy, the gastroscope imaging system acquires the image in the stomach and judges whether there is a suspicious lesion in the stomach according to the image, then the Raman imaging system detects the suspicious lesion, laser light emitted by a laser device is transmitted to a probe through transmission fiber and irradiates on the suspicious lesion to trigger a Raman signal to be sent out, and the probe acquires the Raman signal and transmits the Raman signal to a spectrum analyzer, so that the Raman spectra are obtained. The Raman spectra correspond to molecular structures in an one-to-one mode, molecule-level detection is conducted on the suspicious lesion, and a diagnosis result as to whether corresponding tissue is diseased can be obtained directly. By the adoption of the Raman gastroscope diagnostic unit, real-time, non-invasive and precise molecular pathological diagnosis can be realized during gastroscopy.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a Raman gastroscope diagnostic instrument. Background technique [0002] Gastric cancer is one of the common fatal diseases in humans and one of the most common malignant tumors in the world today, especially in East Asia. If gastric cancer can be detected early during gastroscopy, the survival rate of this population can be significantly improved. [0003] However, the gastroscope currently used in the diagnosis of gastric cancer is a white light reflective endoscopy system, which can only be judged by human vision to a large extent, and can only observe structural changes in human tissue, and obvious changes in human tissue can only be distinguished. Even for experienced doctors, the accuracy of diagnosis is very low if they only rely on the technology of white light reflection endoscopy system. [0004] In order to improve the accuracy of diagnosis, an improved diag...
