A microwave tissue coagulator originally developed to control hemorrhage during hepatic resection has recently found widespread use in the field of minimally invasive surgery. This surgical tool is based on the principle that by radiating a 2450-MHz (12-cm wavelength) microwave from a monopolar antenna within tissue, the heat generated will be limited to within the electromagnetic field generated around the antenna, leading to coagulation of protein in that field. It is therefore possible to use this monopolar antenna as a surgical electrode. The coagulation field is determined by the relationship between the wavelength frequency, tissue-specific permittivity, antenna length, waveform and output, and duration of the irradiation. Since this technique has been applied to devise a new method of hepatectomy, it has also found use in various other surgical fields, such as gastrointestinal tract endoscopic surgery, laparoscopic surgery, and percutaneous surgery. It has also enhanced therapeutic results, notably in cancer therapy.
一种最初为控制肝切除术中出血而研发的微波组织凝固器，最近在微创手术领域得到了广泛应用。这种手术工具基于这样一个原理：通过在组织内的单极天线发射2450兆赫（12厘米波长）的微波，产生的热量将被限制在天线周围产生的电磁场范围内，从而导致该区域内的蛋白质凝固。因此，可以将这种单极天线用作手术电极。凝固场由波长频率、组织特异性介电常数、天线长度、波形和输出以及照射持续时间之间的关系决定。由于这项技术已被应用于设计一种新的肝切除方法，它也在其他各种手术领域得到了应用，如胃肠道内镜手术、腹腔镜手术和经皮手术。它还提高了治疗效果，尤其是在癌症治疗方面。
