Massive hemorrhage is of primary concern during hepatic surgery. In this study, we not only modified the monopolar antenna of the microwave tissue coagulator but also investigated its feasible applications in laparoscopic hepatic surgery. In addition, the conventional antenna of the microwave tissue coagulator was used as a model. A catheter was attached to the antenna. The network analyzer was used to analyze the impedance of the novel monopolar antenna. Moreover, we designed and constructed a novel monopolar antenna for the microwave tissue coagulator. The antenna is gas-leak-proof, having sufficient stiffness and length and retaining similar microwave emission strength, pattern, and shielding property as the conventional antenna. In vitro tests in porcine liver confirm the coagulation and hemostatic effects of the novel type laparoscopic monopolar antenna. Results presented herein confirm the effectiveness of a laparoscopic monopolar antenna for a microwave tissue coagulator with sufficient coagulation effects.
肝手术期间，大出血是首要关注的问题。在本研究中，我们不仅对微波组织凝固器的单极天线进行了改进，还研究了其在腹腔镜肝手术中的可行应用。此外，以微波组织凝固器的传统天线作为模型。将一根导管连接到天线上。使用网络分析仪分析新型单极天线的阻抗。而且，我们设计并构建了一种用于微波组织凝固器的新型单极天线。该天线具有防漏气功能，具备足够的刚度和长度，并且保持与传统天线相似的微波发射强度、方向图和屏蔽性能。在猪肝上进行的体外试验证实了新型腹腔镜单极天线的凝固和止血效果。本文给出的结果证实了具有足够凝固效果的腹腔镜单极天线用于微波组织凝固器的有效性。
