Abstract: A disposable viewable uterus cavity suction tube is used in conjunction with a negative pressure suction system and a display system. A suction opening is at the side wall of the uterus cavity suction tube. A separator is between the suction opening and the front end of the uterus cavity suction tube, which separates the uterus cavity suction tube into the suction cavity and the enclosed imaging cavity. An imaging head and an illumination device are in the imaging cavity. A see-through cover is at the tube wall above the imaging head and illumination device. The angle ? between the central optical axis of the lens of the imaging head and the central normal of the suction opening is a sharp angle. The signal wire of the imaging head and illumination system are installed inside the tube wall. The characteristic of the disposable viewable uterus cavity suction tube is that the lens of the imaging head is a wide angle lens.
