The invention relates to an endoscope, wherein an endoscope body and an endoscope pipe can relatively rotate so that the endoscope can be used for observing without barriers. The endoscope with the rotatable endoscope pipe comprises the endoscope pipe and the endoscope body, wherein the joint of the endoscope pipe and the endoscope body is provided with a rotating wheel, the rotating wheel is fixedly connected with the endoscope pipe and movably connected with the endoscope body, a fixing member is arranged between the rotating wheel and the endoscope pipe, an endoscope pipe optical fiber positioning member connected with the endoscope pipe and rotating synchronously is arranged between the endoscope pipe and the fixing member, an endoscope body optical fiber positioning member fixedly connected with the endoscope body is arranged between the endoscope pipe and the endoscope body, and optical fiber rings are arranged in the endoscope pipe optical fiber positioning member and the endoscope body optical fiber positioning member. The endoscope with the rotatable endoscope pipe has simple structure, is always synchronous in observation and illumination because the endoscope pipe can rotate at any angle relative to the endoscope body, is convenient for use and not limited by the site, and is complete in detection. The invention solves the technical problems that the endoscope body and the endoscope pipe are in an integrated structure to cause incomplete detection or incapability of detection, the structure of the endoscope is complicated and the rotating angle of the endoscope is limited in the prior art.
