Self-coagulation knife treatment for uterine fibroids is a radiofrequency knife (also called self-coagulation needle) as thin as a sweater needle that enters the uterine cavity through the vagina, cervix and other natural cavities under the continuous dynamic observation and guidance of ultrasound, accurately locates the fibroids, automatically and precisely controls its treatment power, time and treatment range, and causes the fibroid cells to dehydrate and coagulate through the biological hyperthermia effect, which is then naturally absorbed and eliminated by the body, so that The uterus will then be absorbed and eliminated by the body, so that the uterus can resume its normal function. The biggest advantage of this method is that it can preserve the uterus intact, does not affect the female endocrine function, can make small fibroids disappear, make the larger fibroids shrink and stop growing, avoid the many complications brought about by surgery, no incision, no hospitalization, the treatment of fibroids can be completed in the outpatient clinic. The process of treating fibroids with self coagulation knife is relatively simple. Due to the local anesthesia, there may be slight pain during the treatment, but most patients can tolerate it. Patients who meet the following conditions can choose this treatment method: 1. between 30 and 45 years old. 2.Healthy without internal diseases, such as heart, brain, liver and kidney diseases, etc. 3.Uterine submucosal fibroids. 4.Single or multiple interstitial fibroids of the uterus with a diameter of less than 3 to 5 cm and better results near the mucosal layer. 5.Subplasmalemma fibroids without a tip. Any kind of treatment method has its limitations. How effective is the treatment of fibroids with self coagulation knife has a lot to do with the choice of its indications. For example, if the fibroids are single, but if they are large, already more than 5 cm, the treatment may not be effective enough to completely inhibit their growth, much less to eliminate them. Another example is that when there are more than 5 multiple fibroids, it is impossible to complete all of them in 1 treatment, and it may be necessary to do it in several sessions; another example is that subplasmalemma fibroids are not well located, and it is difficult to reach the treatment site with the self-coagulation knife. It is also important to note that adenomyoma is a type of endometriosis, and the effect of treatment with the self-coagulation knife is not ideal. Therefore, to achieve a good treatment effect, the indications must be strictly controlled and should never be forced. Self-coagulation knife treatment for uterine fibroids also has complications, besides the common bleeding, infection and pain, there are some less common ones, such as uterine adhesions, menstrual disorders, infertility, recurrence of fibroids, etc. The most serious complication is organ damage, including intestinal tube, bladder and ureter. Although the chances of these serious complications are not high, they are indeed a possibility. The advantages of treating uterine fibroids with self-coagulation knife are convenience, simplicity, and low cost, while its disadvantages are limited effectiveness in treating large fibroids, subplasmic fibroids, and multiple fibroids. Another more important point is that the application of self coagulation knife for uterine fibroids requires a more demanding surgeon, who must not only have extensive clinical work experience, but also have a rigorous scientific attitude, excellent operating techniques and close cooperation with the ultrasound doctor.
