Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a microwave ablation therapeutic apparatus for treating hysteromyoma.
Background
Uterine fibroid is one of the most common benign tumors in female reproductive organs, and is also one of the most common tumors in human body, which is also called fibroid and uterine fibroid. The hysteromyoma is mainly formed by hyperplasia of uterine smooth muscle cells, and a small amount of fibrous connective tissue exists as a supporting tissue, so the hysteromyoma is known to be more definite. For short, hysteromyoma. Most patients are asymptomatic and only occasionally found on pelvic or ultrasound examinations. If the symptoms exist, the disease is closely related to the growth position, speed, degeneration and complication of the myoma, and the relationship with the size and number of the myoma is relatively small. Patients with multiple subplasmic leiomyomata are unlikely to be symptomatic, while a smaller subplasmic leiomyomata often causes irregular vaginal bleeding or menorrhagia.
The clinical treatment demand of hysteromyoma is very extensive. Surgical removal of fibroids or uterus is still a common treatment, but has the disadvantages of being traumatic or not capable of retaining the uterus. The uterus protection is of great significance at the present day when the minimally invasive treatment technology is mature, especially about the policy of Du-Bi. The transvaginal microwave ablation treatment technology has been successfully applied in the field of treatment of hysteromyoma, but how to combine the advantages of the microwave ablation technology is yet to be deeply researched. Although microwave ablation has been primarily applied to treatment of hysteromyoma, the existing microwave ablation antenna is not beneficial to treatment from the uterine cavity surface through vagina, microwave ablation through abdominal puncture not only artificially destroys the integrity of the endometrium, but also easily causes damage to the adjacent intestinal canal and bladder, and the treatment speed is low and the visualization degree is low.
The principle of microwave treatment of diseases is complex and is mainly achieved by thermal and biological effects. Because the magnetic resistance existing between polar molecules generates resistance effect on oscillation, microwave energy is consumed to generate heat, and the aim of treating diseases is achieved by utilizing the heat, namely the heat effect of microwave treatment. The microwave therapy is characterized in that high-frequency local radiation is adopted, and a certain treatment effect can be achieved under the condition of smaller microwave power output. The microwave energy can be absorbed by the tissue to generate an internal heat source, and the effective action depth on the human tissue is 5-7 CM. The microwave has the advantages of high efficiency of heat effect on human tissues, strong penetrating power and capability of simultaneously generating heat inside and outside.
A large number of studies at home and abroad prove that the tumor cells shrink to die at the temperature of 42.5-43.5 ℃. After microwave heating has occurred, there are two ways to treat tumors: one is microwave irradiation from outside; alternatively, microwaves are delivered to the patient to directly irradiate the tumor, and the two treatment modes can be selected according to the lesion position. When microwave acts on body tissue, it can cause high-frequency vibration of ions, water molecules and dipoles in tissue cells. When the microwave output energy is low and the radiation heat energy is low, the local blood circulation can be enhanced, the local metabolism can be accelerated, and the local immunity can be enhanced, so that the local blood circulation can be effectively improved, the absorption of edema can be promoted, and inflammation and pain can be relieved.
The microwave ablation for treating the hysteromyoma has the following advantages: uterus is kept, physiological structure of the pelvic cavity is not damaged, and the hysteromyoma is inactivated and obviously reduced until the hysteromyoma disappears after treatment. Has no obvious influence on the function of the ovary, and the menstrual cycle of the patient in the current month after the treatment is normal. Without operation, the treatment method comprises puncturing the focus from vagina via uterus, and implanting microwave needle. Simple, rapid, effective and safe operation and small wound. The hospitalization time is short, and only 1-2 days are needed.
