In this biopsy system, when the distal end of a sheath (7) is located within the visual field of an optical imaging mechanism, the open surface of a needle tube (3) is located proximal to a sloped section (107a) and the position of the needle tube (3) is fixed with respect to an ultrasonic endoscope (100) by a fixing mechanism (50) so that the direction of the slant of the open surface and the direction of the slant of the sloped section (107a) coincide. |
