Hysteroscopy should be considered a minor surgery. In general, the surgery is judged by two main indicators, one is the cost of the surgery, and the other is the trauma of the surgery, such as wounds on the body. If the cost of these two aspects is relatively small, for example, the cost of hysteroscopy is relatively small, mainly for the internal operation of the uterine cavity, such as the removal of polyps in the uterine cavity, or the removal of the uterine cavity of the uterine cavity of the relatively small uterine fibroids, can be used in the use of hysteroscopy. During the use of hysteroscopy, there is no wound on the surface of the body, because it enters the body through the natural cavity to perform surgical operations. Therefore, from the above two indicators, both in terms of cost and wound, it should be a relatively small operation.
