Principle of radiofrequency needle therapy

Radio frequency is a kind of high frequency vibration up to 150,000 times per second. The human body is a complex structure composed of many organic and inorganic substances. Body fluids contain a large number of dielectrics, such as ions, water, colloidal particles, etc. The human body mainly relies on ions to move and conduct current. Under the action of high frequency alternating current, the concentration change direction of ions changes with the direction of current for positive and negative half cycles. Under high frequency oscillation, the ions between the two electrodes move rapidly along the direction of the power line and gradually change from the moving state to the vibrational state. Due to the different size, mass, charge and moving speed of various ions, ions rub against each other and collide with other particles, resulting in biothermal interaction. Due to the poor heat dissipation of the tumor, the temperature of the tumor tissue is higher than that of its adjacent normal tissue. In addition, cancer cells are sensitive to high heat, and high heat kills cancer cells without side effects
