Endoscope device

An endoscope device comprises an endoscope body, an inner tube and an outer tube. The endoscope body is provided with a body far-end part, and at least one part of the inner tube protrudes out of the body far-end part and is provided with an inner tube far-end part far away from the body far-end part. The inner tube has a first inner tube opening near the distal end of the body and a second inner tube opening near the distal end of the inner tube. The outer tube is configured to at least partially cover the protruding portion of the inner tube. The outer tube has a first outer tube opening near the distal end of the body and a second outer tube opening near the distal end of the inner tube. The inner pipe and the outer pipe can move and rotate relative to each other so as to change the relative position between the first inner pipe opening and the first outer pipe opening and the relative position between the second inner pipe opening and the second outer pipe opening. 一种内视镜装置，其包含内视镜本体、内管及外管。内视镜本体具有本体远端部，内管至少
