经皮射频热切除术(percutaneous radiofrequency thermal ablation)是国外近年来开展的一项有效而快速损毁肝脏恶性肿瘤的新技术,其机制是通过经皮影象技术,以热传导的方式导致肿瘤组织发生凝固性坏死。1999年我院引进国内第一台自动控制射频治疗仪,并对75例患者成功地进行了治疗。现将该技术及临床运用概况做一介绍。 1 技术概况 1.1 仪器及其性能 射频(radiofrequency,RF)治疗仪主要由RF发射器、针式治疗电极(active needle electrcxle)、弥散电极板(dispersise electrode)及B超监视系统等部分组成。工作流
Percutaneous radiofrequency thermal ablation is a new technique that has been effectively carried out in recent years abroad to quickly destroy liver malignancies. Its mechanism is to induce the coagulation of tumor tissue by means of thermal conduction through transcutaneous imaging technology. Necrosis. In 1999, our hospital introduced the first automatic radio frequency therapeutic apparatus in China and successfully treated 75 patients. This technique and clinical application profile are introduced. 1 Technology Overview 1.1 Instrument and Its Performance The radiofrequency (RF) therapy instrument consists of an RF transmitter, an active needle electroscopic electrode, a disperse electrode plate, and a B ultrasound monitoring system.
