13. The system of claim 12, further comprising: the endoscope all-in-one machine comprises an endoscope all-in-one machine, a resectoscope power host, a fluid management host, a liquid injection container and a liquid collection container;

the exciser power host is connected with the exciser and used for providing power for the exciser to dissect the dissected tissue adhered on the tissue adhesion piece;

14. The system of claim 13, wherein the endoscope all-in-one machine is electrically connected with the air pressure sensor and is configured to receive an air pressure value in the sealed outer cavity detected by the air pressure sensor, and determine whether the tool bit of the knife tube contacts the uterine cavity wall based on the air pressure value, so as to count and display a training error rate based on the determination result.

15. Use of a uterine cavity simulator as defined in any one of claims 7 to 11 in a uterine cavity simulation training system.
