1.Laparoscopic surgery Laparoscopic surgery is an operation performed by a doctor using special laparoscopic instruments that integrate optical, computer, ultrasound, mechanical and other technologies. The basic procedure of the surgery is: after the patient is anesthetized, the doctor punches 3-4 small holes of 0.5-1cm in diameter in the patient’s abdominal wall, and one of the holes is placed into a mirror. The mirror is connected to the TV screen through a miniature camera, making the lesion in the patient’s abdominal cavity visible on the TV screen. Several other small holes in the abdominal wall are placed into scissors, forceps and other surgical instruments, and the surgeon looks at the screen to perform the surgery. The surgical procedure is basically the same as open surgery, because the mirror has the role of magnification 8-10 times, and can even do more fine than open surgery, the doctor looked at the screen to the lesion of the tissue for a series of operations such as clamping, cutting, suturing. At the same time, the application of advanced technologies such as electric knife, argon knife, laser and microwave in the operation makes the operation more perfect. Finally, the excised mass is placed in a plastic bag and shredded and removed, or removed directly from the vagina. Laparoscopy has a history of 103 years, and with the continuous improvement of surgical instruments and equipment and the continuous improvement and maturation of surgical operation skills, the clear vision, coupled with the magnification effect, advanced and dexterous operation instruments with little interference to the surrounding organs, etc., make the more complicated gynecological surgery can be successfully completed under laparoscopy, realizing the “minimally invasive “The hysteroscopy technique 2, hysteroscopy technology Hysteroscopy originated in 1869, also known as hysteroscopy. With the rapid development of science and technology, hysteroscopy is now divided into panoramic hysteroscopy, contact hysteroscopy and microscopic hystero-vaginoscopy. The hysteroscope is used to open the uterus by activating the irrigation system before the procedure, which ensures intrauterine pressure and also serves as a cooling flush. The hysteroscope is divided into an examination hysteroscope and a surgical hysteroscope. There are three different electrodes in the surgical hysteroscope, which work properly with the support of the energy system, i.e. the electric current. In addition, a light source system and an imaging system are needed to help for the accuracy of the surgery. During the surgery, with clear lighting and monitoring by the imaging system, it avoids blurred vision and can play a guiding role. Hysteroscopy not only determines the site, size, appearance and scope of the presence of the lesion, but also provides a detailed observation of the tissue structure on the surface of the lesion, and removes or positions the uterus for scraping under direct vision, which greatly improves the accuracy of the diagnosis of diseases in the uterine cavity and updates, develops and makes up for the deficiencies of traditional treatment methods. Indications for hysteroscopic treatment include: uterine bleeding such as excessive menstruation, frequent menstruation, prolonged menstruation, irregular uterine bleeding, dysfunctional uterine bleeding, submucosal fibroids, endometrial polyps, infertility and recurrent spontaneous abortion; those with abnormalities or suspicions suggested by ultrasound, hysterosalpingography or diagnostic scraping can be confirmed, verified or excluded by hysteroscopy; those with intrauterine cavity adhesions or intrauterine cavity For those with intrauterine adhesions or intrauterine residues, the latter includes fetal bone fragments, etc.; for those suspected of endometrial cancer and its precancerous lesions, the application of hysteroscopy, localized biopsy combined with histopathological evaluation can help early diagnosis and timely treatment; with appropriate patient selection and complete preoperative preparation, certain hysteroscopic procedures can replace or improve traditional treatment methods. 3.Radiofrequency ablation technology Radiofrequency ablation is a high frequency electric knife made by the thermal effect of radiofrequency current, through the biothermal effect of 60-80 ℃ to make the lesion tissue thermal coagulation death or apoptosis, myoma degeneration, necrosis, atrophy, lesion tissue and nerve inactivation, to prevent the lesion tissue continue to grow, no obvious damage to surrounding tissues, surgery through the vagina, cervix, uterine cavity natural cavity operation, no effect on the lower genital tract, does not It does not affect the sexual function and bladder function, and has no effect on the anatomical position and innervation of the bladder. Currently, radiofrequency ablation technology has been widely used in clinical practice. It provides treatment opportunities for patients who are not suitable or unwilling to undergo surgery and can preserve their normal tissues to the maximum extent. In the field of gynecology radiofrequency ablation technique is adapted to patients with vulvar inflammation, vulvar and/or perineal warts, vestibular gland cysts, vestibular gland abscesses, cervical erosion, dysfunctional uterine bleeding, uterine fibroids and adenomyosis. 4, gynecological negative surgery Gynecological negative surgery has the advantages of no incision on the abdominal wall, little damage, fast recovery, short hospitalization time, low hospitalization cost and easy acceptance by patients, which fully demonstrates the advantages of minimally invasive surgery. Some foreign experts believe that “under the same conditions, if it is possible to perform a femoral operation, it is appropriate to perform a femoral operation as much as possible. With the proficiency of transvaginal surgery and the development of special surgical instruments, the indications for surgery have been expanded, and it has been reported that it is possible to perform large non-prolapsed hysterectomy at 12-16 weeks of pregnancy, so it has been preferred by some gynecologists. However, this method is difficult to deal with uterine fibroids that preserve the uterus (except for submucosal fibroids that prolapse out of the cervical opening), cannot preserve the cervix, has certain technical difficulties in surgical operation, such as difficulties in vaginal removal of large fibroids, pelvic adhesions, adnexal lesions, history of lower abdominal surgery, vaginal stenosis, etc., which increase the difficulty of surgery and increase the chance of damaging the bladder and rectum or change the surgical method, thus making this procedure limited. 5.Interventional therapy The purpose of interventional therapy applied to gynecological malignant tumors is fivefold: (1) neoadjuvant chemotherapy before cancer surgery, the purpose is to eliminate the tiny metastases and subclinical foci around the cancer foci, so that the surgical resection can be more complete; at the same time, it can be administered before the blood vessels and lymphatic vessels at all levels of the tumor are damaged, so as to increase the concentration of local chemotherapeutic drugs in the tumor and achieve the effect of efficient killing of cancer cells; it can also reduce the size of the tumor and reduce the complications of surgery. It can also shrink the tumor lesions, reduce the complications of surgery, or make the patients with middle and late stage tumor who have lost the chance of surgery get the chance of surgery to create conditions for follow-up treatment. (2) Palliative treatment for postoperative recurrence has the advantages of minimally invasive and reproducible. (3) For certain gynecologic malignancies, such as trophoblastic cell tumors, mesotherapy can also be used as a radical treatment. (4) Intraskeletal arteriovenous fistulas due to gynecologic malignancies. (5) Hemostasis treatment for bleeding caused by gynecologic malignancies and bleeding complicated by radiotherapy. In summary, the role of minimally invasive techniques in the treatment of gynecological diseases is gaining more and more attention because of their advantages of less trauma, less bleeding, lower postoperative complications, faster recovery and shorter hospital stay. The selection of its specific methods should tend to be individualized, and the optimal plan should be designed according to the patient’s age, symptoms, fertility requirements, size and location of lesions, general condition, economic ability, hospital technology, etc., to achieve the best treatment results. However, the importance of preoperative diagnosis should be emphasized, as some of the surgeries are unable to obtain specimens for pathological examination, so malignant tumors should be excluded preoperatively. With the continuous development of science and technology and the accumulation of clinical experience, minimally invasive techniques will occupy a dominant position in the treatment of gynecological diseases in the near future after summing up and improving.
