[0002] Endoscopic biopsy is a method of taking a living tissue for examination through an endoscope. The focus of digestive endoscopy is to find lesions and make corresponding diagnoses. Because there is a certain inconsistency between the morphological judgment of the naked eye under the endoscope and the nature of the disease, it is necessary to take a living tissue for pathological examination to confirm the diagnosis. During endoscopic microbial culture, multiple staff members are often required to cooperate: some need to lift the tube, some need to flush the biopsy channel of the endoscope, and another person needs to operate the endoscope head to make the culture fluid for flushing the biopsy channel flow into the culture bottle. The overall operation is relatively cumbersome and is not conducive to improving work efficiency. The Chinese utility model patent with application number 202321671390.6 discloses an auxiliary bracket for flushing the endoscopic biopsy channel.
