Amid the rapid advancement of minimally invasive interventional medicine, medical radiofrequency ablation (RFA) therapy devices have emerged as critical tools in gynecological cervical procedures and gastrointestinal treatments—such as hemorrhage control, polyp cauterization, and the cutting/coagulation of fibroids and tumors—due to their precision ablation and high controllability. By enhancing therapeutic outcomes while significantly reducing patient trauma risks, they have pioneered new pathways in clinical treatment.

I. Core Mechanism of Action

Radiofrequency (RF) technology is a state-of-the-art and mature low-temperature surgical technique. Its working principle involves using radiofrequency waves to induce collisions and friction between charged particles in intracellular/extracellular fluids and other ions, generating ionic heating within biological tissues. Simultaneously, water molecules and protein molecules collide and rub against surrounding molecules, producing "dipole heating." These two heating mechanisms act synergistically on the tissue, creating a unique endogenous thermal effect. This effect triggers spontaneous coagulation of tissue proteins, leading to subsequent atrophy or necrotic shedding of targeted cells.

II. Clinical Applications of Radiofrequency Therapy Devices

The radiofrequency therapy devices produced by Simon Medical (a Chinese medical device manufacturer) are primarily used for:

Gynecological conditions: dysfunctional uterine bleeding, cervical intraepithelial neoplasia (CIN), cervical erosion, cervicitis, cervical cysts, cervical hypertrophy, genital warts, intraoperative hemostasis in gynecological surgeries, uterine fibroids, and vulvar leukoplakia.

Gastroenterology: Additionally, they have extensive clinical applications in treating gastrointestinal disorders.

III. Technical Advantages of Simon Radiofrequency Ablation (RFA) Therapy Devices

Endometrial ablation via radiofrequency ablation does not require anesthesia and is a simple procedure suitable for all patients who can tolerate curettage. It involves minimal intraoperative bleeding, does not require uterine distension, and has relatively low technical demands. For patients, it offers lower medical costs and no significant intraoperative or postoperative complications. Literature reports indicate that the cure rate three months post-treatment with radiofrequency ablation is approximately 96.3%.

IV. Treatment Safety

Precise Localization: Ultrasonography enables real-time visualization of the radiofrequency needle, ensuring accurate guidance and placement into the targeted fibroid area. The entire procedure is continuously monitored, posing no trauma to either the patient or medical staff.

Controllable Effects and Range: During treatment, ultrasonography precisely tracks the extent of fibroid deformation. The scope of thermal effect can be regulated by adjusting the power output and radiofrequency needle configuration.

Targeted Therapy: The radiofrequency needle initiates coagulation directly from the central region of the fibroid, achieving focused therapeutic action.

Capsule Barrier Effect: The fibrous capsule surrounding uterine fibroids acts as a natural barrier to inhibit outward thermal diffusion.

V. Development Trends Outlook

Clinical data indicate that the cure rate for uterine fibroids (adenomyosis ≤0.5 cm) reaches 97%, dysfunctional uterine bleeding achieves a 91.58% cure rate, and cervical erosion demonstrates a 97.03% cure rate. Radiofrequency ablation technology is performed under real-time B-ultrasound guidance, enabling direct visualization and easy monitoring during the procedure. This approach requires no laparotomy and preserves normal tissue integrity, thereby fully maintaining uterine and pelvic structural completeness. As a representative technology of precision medicine, radiofrequency ablation therapeutic devices are driving a paradigm shift in clinical practice from "traumatic treatment" to "microwave ablation." Characterized by minimal invasiveness and high efficacy, this technology continues to advance multidisciplinary clinical development through its innovative diagnostic and therapeutic capabilities.
