Fluorescent endoscope for esophageal cancer clinical operation

Abstract

The invention discloses a fluorescent endoscope for an esophageal cancer clinical operation, and belongs to the field of fluorescent endoscopes. According to the fluorescent endoscope for the esophageal cancer clinical operation, in the process of inserting an endoscope main body into an endoscope hole, a locking plate is used for compacting a locking rubber block, local fixing of the locking rubber block is achieved, and then the movable range of the endoscope main body is reduced; when a medical worker operates the endoscope body and the front end of the endoscope body rotates in the same plane, locking of the locking plate on the locking rubber block cannot be relieved, the movable range of the endoscope can be reduced in the process of finding a focus through the endoscope, unnecessary injuries to a patient due to misoperation are not likely to be caused. When the endoscope body needs to be taken out, only the endoscope body needs to be pulled upwards, in the process, in order to save force, the endoscope body needs to be pulled out in the direction perpendicular to an auxiliary block, and secondary damage to a patient in the pulling-out process of the endoscope body can be effectively avoided.

Description

technical field [0001] The invention relates to the field of fluoroscopy, in particular to a fluoroscopy for clinical operation of esophageal cancer. Background technique [0002] Fluorescence Laparoscope, also known as endoscopic fluorescein contrast imaging system, has the functions of endoscopic imaging system and fluorescein angiography imaging system, providing real-time real-time high-definition white light and high-definition fluorescence imaging system for endoscopic surgery. Combining with protein, it is metabolized and excreted in the body, so as to provide lesion inspection in different parts, which enables surgeons to better grasp the anatomical structure of small scattered, hidden and invisible tumor displacement lesions before surgery, using advanced Advanced sensor technology and a camera with a specific optical system provide more realistic color and high-contrast images with less noise in all precise display modes, so that doctors can better achieve fundamen...

AI Technical Summary

Problems solved by technology

[0004] Fluorescence laparoscopy is actually an upgraded surgical method of laparoscopic surgery. Using the difference in the metabolic rate of the lesion organ from that of the normal organ, a large amount of fluorescent substances are accumulated in the lesion organ, which is convenient for doctors to accurately and quickly determine the extent of the lesion during the operation. Compared with the thoracic cavity and abdominal cavity, the pharyngeal cavity where esophageal cancer is located is smaller, and there is less room for doctors to operate. In the process of using laparoscopic lesions to find lesions, it is easy to cause misoperation to the patient. Cause unnecessary injury and affect the effect of surgery
