Over a period of more than 100 years, radiofrequency energy has been introduced in many fields and applications in medicine. At present, radiofrequency constitutes the basis of numerous medical devices employed in almost all medical specialties. It is particularly applicable and valuable in various minimally invasive procedures for its locally focused effects. Radiofrequency energy is a technical term established to describe high-frequency alternating electrical currents (with a frequency ranging from 300 kHz to 3 MHz) and their impact on biological tissue. The application of RF energy causes controlled tissue heating with consequent cell protein denaturation and desiccation, which leads to cell death and tissue destruction. The primary principle of radiofrequency is that the generated heat can be used to cut, coagulate or induce metabolic processes in the target tissue. The authors of this paper offer a comprehensive and compact review of the definition, history, physics, biological principles and applications of radiofrequency energy in current surgery.
在100多年的时间里，射频能量已被引入医学的许多领域和应用中。目前，射频是几乎所有医学专科所使用的众多医疗设备的基础。由于其局部聚焦效应，它在各种微创手术中特别适用且具有价值。射频能量是一个技术术语，用于描述高频交流电（频率范围为300 kHz至3 MHz）及其对生物组织的影响。射频能量的应用会导致可控的组织加热，进而引起细胞蛋白质变性和干燥，导致细胞死亡和组织破坏。射频的主要原理是所产生的热量可用于切割、凝固或诱导目标组织中的代谢过程。本文作者对射频能量在当前外科手术中的定义、历史、物理原理、生物学原理及应用进行了全面而简洁的综述。
