[0109] Optionally, the first matching structure 24 and the second matching structure 31 are matching snap-fit ​​structures, threaded structures or locking structures.

[0110] In a specific embodiment, the first matching structure 24 and the second matching structure 31 are matching thread structures.

[0111] In a specific embodiment, the scope assembly 2 has a Y-shaped structure, including a lens barrel 21 and an eyepiece 22 connected to the lens barrel 21 at a certain inclination angle; wherein the lens barrel 21 and the eyepiece 11 are realized by the scope body and rod-shaped mirror described in the patent application entitled "A Hysteroscopic Endoscope and Endoscopic Treatment System" (patent number 202121476565.9), which will not be repeated here.

[0112] In summary, the drainage assembly and hysteroendoscopic device provided by the utility model, by providing a docking structure between the drainage assembly and the hysteroendoscopic body, can realize the connection between the drainage assembly and the hysteroendoscopic body, and at the same time, the drainage assembly can rotate around the axis relative to the hysteroendoscopic body, so that when the doctor uses the hysteroendoscopic device for diagnosis and treatment, he can adjust the rotation angle of the drainage assembly to perform corresponding diagnosis and treatment operations. In summary, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
