Application scope
Radio frequency surgical electrosurgery is suitable for use in minimally invasive and fine surgical departments such as plastic surgery, dermatology, stomatology, gynecology/LEEP surgery, ophthalmology, otolaryngology, spine surgery, neurosurgery, etc. In the field of cosmetic plastic surgery, RF mainly has two uses: skin tightening and body contouring. In addition, RF also has good efficacy in the treatment of scars, acne, etc.
Radiofrequency (RF) technology is increasingly used in dermatology to achieve skin regeneration with minimal side effects and downtime. Radiofrequency technology allows doctors to increase the target tissue layer while protecting melanocytes and the skin surface, thereby preventing dyspigmentation and prolonged wound healing. Recent advances in radiofrequency technology have expanded the range of treatment indications and improved cosmetic outcomes.
Principle
When the radiofrequency knife electrode guides high-frequency radio waves through the human body, the polar water molecules in the human tissue oscillate to generate low-temperature heat energy. Different surgical effects can be achieved by adjusting the waveform of the radio waves. Full-filtered radio waves are used to oscillate water molecules in cells to generate heat, vaporize and decompose cells to achieve pressure-free fine cutting; full-wave rectified waveforms can denature the collagen of the blood vessel wall of the tissue and shrink and merge the broken ends of blood vessels to achieve a hemostatic effect; partial rectification The waveform can cut and stop bleeding of tissue at the same time. Electron wave knife can only cut tissues and organs containing water. The more water content in the tissue being cut, the better the cutting effect will be.
Radio frequency technology causes intracellular water molecules to move violently under the action of 4.0MHZ/1.71MHZ radio frequency electromagnetic waves, causing cells to expand and rupture, thereby achieving low-temperature cutting or ablation functions. The violent movement of molecules generates a certain amount of heat, thereby achieving coagulation of tiny blood vessels.
Ordinary high-frequency electrosurgery (generally output frequency 400KHZ-750KHZ) uses electrical energy to convert into heat energy to partially carbonize tissues, thereby achieving cutting and coagulation. Relatively speaking, radiofrequency technology causes less thermal damage to tissues during surgery and is very suitable for precise minimally invasive surgery.
Features
1.Compared with high-frequency electrosurgery, the radiofrequency electrosurgery electrode itself generates less heat, so the thermal damage to both sides of the affected tissue is low. Research shows that the range is only 0.01 mm to 0.02 mm, and will not cause damage caused by ordinary high-frequency electrosurgery. The tissue pulling phenomenon can be used for fine surgical operations and tissue biopsy in body cavities and lumen. Because the tissue carbonization caused by radiofrequency knife is light and the boundary between it and normal tissue is obvious, the tissue heals quickly and the scar is small.
2.Because there is no current passing through the human body, the radiofrequency electromagnetic wave knife has no effect on the electronic devices in the body. This will not have any adverse effects on patients with electronic devices implanted in the body.
3.The RF knife head can sterilize itself, and it also has a certain effect on infected wounds or wounds.
4.It can assist doctors in completing almost all surgical incisions, coagulation and hemostasis, with little side damage, good effect and easy to use.
Advantages
1.High-frequency radiosurgery is composed of a variety of electrodes, including ring-shaped, spherical, needle-shaped, triangular, square, etc.

2.Includes all functions of radiofrequency technology: cutting, coagulation, ablation, evaporation, clearing, contraction, and electrocautery (including all functions of laser and electrosurgery without their side effects).
3.Due to the ultra-high frequency, the skin effect is more obvious, so minimally invasive and precise surgeries can be performed, and surgical effects that cannot be achieved by traditional electrosurgical surgery can be achieved.
4.Minimally invasive: pressure-free cutting, little tissue damage (the depth of damage is less than 20 microns, there is little fiber formation, and scars rarely occur after surgery).
5.The phenomena of tissue pulling and carbonization caused by traditional electrosurgery rarely occur. About 2/3 of patients can obtain tissue specimens that do not affect pathological examination.
6.It is less painful, requires no anesthesia or only uses local infiltration anesthesia, and has few complications (less bleeding and infection).
7.Safety: The negative plate is an insulating plate and does not need to be in direct contact with the patient to avoid high-frequency burns.
8.There are no special requirements for the operating room and can be performed in the outpatient clinic.
9.One-time radical cure: no recurrence, eliminating the shortcomings of traditional methods such as unsatisfactory efficacy, long course of treatment, easy recurrence, and long-term treatment.
10.Small trauma: no damage to the normal tissue of the cervix, smooth incision, no scars, and no impact on reproductive function and quality of life of couples.
11.Less pain: no pain and fewer surgical complications (bleeding, infection).
12.Short course of treatment: The operation time is short, the operation can be completed in 5 minutes, no hospitalization is required, and work and study are not affected.
13.Integrity of tissue specimens: It is not easy to cause tissue elongation and carbonization during traditional electrosurgical cutting, and intact tissue specimens that do not affect pathological examination can be obtained.

Conclusion
Radiofrequency technology continues to advance rapidly, providing dermatologists with an increasing number of skin rejuvenation techniques that produce few side effects and minimal downtime for patients. Radiofrequency treatment allows doctors to increase the target tissue layer while also protecting melanocytes and the skin surface, thereby preventing abnormal pigmentation and delayed wound healing. Radiofrequency technology is an exciting and expanding technology in the field of cosmetic dermatology, and future developments are likely to continue to improve the therapeutic index of RF, tailoring treatment options to individual patients, while combining RF with other treatments. , and explore and expand the scope of its therapeutic indications.
