The following is a detailed description by way of specific examples.

Example one

An embodiment of the present invention provides a uterine cavity endoscope, as shown in fig. 1, which is a three-dimensional structure example of the uterine cavity endoscope, and the uterine cavity endoscope includes: a working mirror tube 1, a mirror body 2 and a water channel component 3. Wherein:

the working endoscope tube 1, the endoscope body 2 and the water channel component 3 are hollow structures and are sequentially connected to form an instrument channel, and the instrument channel can be used as an overflow channel or an insertion channel of a therapeutic instrument;

the end of the water channel assembly 3 far away from the working lens tube 1 is provided with a first butt joint part 33, and the first butt joint part 33 is used for matching and connecting with an overflow channel or a second butt joint part on a therapeutic apparatus.
