The image channel is arranged below the light beam channel, the light beam channel is arranged above the image channel, and the plug is arranged outside the light beam channel, so that the upper half part of the sheath can be effectively plugged, the water inlet can not be sucked away at once, and a water circulation passage is formed.

Preferably, the mirror body is connected with an eye mask through a connecting rod, the mirror body is parallel to the eye mask, and two turning prisms are respectively arranged at two ends of the connecting rod. The distance between the axis of the eyeshade and the axis of the mirror body ranges from 60mm to 130 mm. The light is emitted from the eyeshade through the turning of the two prisms, and the eyeshade is connected with the CCD camera system to transmit the image of the operation part to the monitor. The eyeshade is parallel to the endoscope body, and enough space is reserved for convenient observation, so that the hysteroscope is suitable for use requirements.

Preferably, the side surface of the endoscope body is provided with a light guide beam inlet, the rear end of the endoscope body is provided with an instrument inlet and a liquid inlet, the light guide beam inlet is connected with a light guide beam channel in the endoscope, and the instrument inlet and the liquid inlet are connected with the working channel.

Therefore, the utility model discloses a hysteroscope possesses following advantage: the hysteroscope is accurate in positioning, and can distinguish blood vessel distribution and pathological changes under the mucous membrane; the operation is convenient, different instruments can be selected according to the operation process, the endoscope does not need to be moved, and only the instruments in the working channel of the endoscope need to be changed; the risk is reduced, the operation is performed under the visual condition in the whole operation process, the leakage of the pathological tissues is not needed to be worried, and the accidental injury caused by the invisible operation is not needed to be worried.
