<p>An endoscope with a sampling device which can positively and quickly take samples of deposits on the inner wall of a pipe or the like or of cells on the inner wall of a body cavity when inserted through a forceps channel (22) in the endoscope (11). For taking samples purely by a suction action within a pipe, or in a living body, samples cannot be easily obtained in some cases, as positivity force is lacking, and if it is necessary to sample a powder, simultaneous scraping and sucking actions are required to obtain the powder sample. Therefore, in an endoscope constructed in accordance with the present invention the sampling device is a hollow suction tube (22) which can be inserted through a channel (20) in the endoscope (11), and a scraping means (26) formed near an opening (27) at the tip of the suction tube (22), the tube (22) being connected at the rear hand grip to a suction means (24) to suck samples that are scraped off by the scraping means (26) so as to positively extract the samples.</p> |
