Description

Endoscope with sampling function Technical Field The invention relates to the field of medical instruments, in particular to an endoscope with a sampling function. Background Endoscopes are commonly used as intra-luminal viewing and medical instruments in the clinic, and typically require tissue sampling to be accomplished while viewing the lesion for subsequent pathological examination and diagnosis. The existing sampling endoscope is mostly a single sampling forceps, in actual operation, one-time sampling can be usually completed at one position, and when multi-point sampling is required for different positions and different suspected lesions, the sampling forceps are usually required to be replaced (multiple advance and retreat), so that the whole sampling process is not convenient enough and the efficiency is low. In addition, in the prior art, after sampling is completed, it is often difficult to effectively isolate the acquired samples from the surrounding environment and samples acquired at different positions, and there is a risk that the samples are in contact with each other to cause pollution, so that the independence and the reliability of the samples are not guaranteed.
