The application of high-energy focused ultrasound for the treatment of chronic cervicitis has the following advantages: 1, less side effects, repeated treatment; 2, short treatment time, no smell, no smoke; 3, no trauma, no or very little bleeding during the procedure; 4, less vaginal discharge after treatment, short time, less bleeding from debridement; 5, no scar formation after the procedure, does not cause cervical adhesions, especially suitable for the treatment of women who have not had children. Chronic cervicitis is one of the most common gynecological diseases, mostly treated locally. Although local medication is effective, the most common and effective treatment is still physiotherapy. The principle of physiotherapy is to destroy the erosive surface of the cervix by various physical methods (cold or heat) so that it is covered by new cervical epithelium after necrosis and detachment. It takes 3 to 4 weeks for healing, and about 6 to 8 weeks for deeper lesions. At present, the common clinical methods include laser, freezing, infrared coagulation and microwave, etc. The efficacy of each treatment method is similar. However, physical treatments such as laser have the risk of causing postoperative cervical canal stenosis and infertility, and postoperative cervical scar formation may even cause cervical adhesions, which may affect future fertility. Therefore, physical therapy should be chosen carefully for young women or women who have not yet had children. High-energy focused ultrasound therapy technology, as a new non-invasive local treatment, can well compensate for the shortcomings in the above treatment. Since ultrasound has good tissue penetration, ultrasound can act from deep to shallow cervical tissue after the contact between the treatment head and the cervix, and treat cervical lesion tissue through the thermal effect, cavitation effect and other biological effects produced by the interaction between ultrasound and biological tissue; since the cells of lesion tissue are more sensitive to the effect of ultrasound, it can selectively destroy deep lesion cells and protect normal tissue; in addition, it can also In addition, it can make the body’s fiber cells and enzyme activity, improve circulation, absorb inflammation, improve tissue nutrition, play its role in tissue repair and treatment of lesions, and finally achieve complete cure. Focused ultrasound is accurately positioned in the treatment of cervical lesions, and in the treatment of cervical erosion, there is less crusting reaction, no heavy bleeding due to crusting off, and no scarring after healing, and good tissue elasticity can be maintained; therefore, there is no cervical scarring, stenosis and other after-effects. Treatment of chronic cervicitis has long been tricky for infertile women, especially those suffering from infertility or worried about the impact on fertility. On the one hand, chronic cervicitis causes thick cervical secretions that are not conducive to the passage of sperm, and the increase in local leukocytes can also kill sperm. Thorough treatment of chronic cervicitis is conducive to conception, and it seems more effective and reasonable to consider fertility after curing cervicitis; on the other hand, most traditional physical treatments have the potential danger of affecting fertility. Now, this long-standing problem of physicians and women with cervicitis has been solved with the application of high-energy focused ultrasound therapy, which is good news for women with cervicitis.
