Principles of radiofrequency needle therapy

Radio-frequency needle
Radio frequency is a type of high-frequency vibration with a frequency of 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 dielectric, such as ions, water, colloidal particles, etc. The human body mainly relies on ion movement to conduct current. Under the action of high frequency alternating current, the direction of ion concentration changes with the direction of current positive or negative half cycle. Under high frequency oscillation, the ions between the two electrodes move rapidly along the direction of the power line and gradually change from a moving state to a vibrating state. Due to the different size, mass, charge and moving speed of ions, ions rub against each other and collide with other particles, resulting in biothermal action. Due to the poor heat dissipation of the tumor, the temperature of the tumor tissue is higher than that of the adjacent normal tissue. In addition, cancer cells are sensitive to high heat, which kills cancer cells without side effects
