    • A tissue ablation system is described that generates a uniform avascular plane of coagulated tissue to aid in the bloodless or near-bloodless resection of various biological tissues from a variety of organs. The tissue ablation system includes an energy director guide and two or more sets of bipolar energy directors. The energy director guide includes a series of channels that configure the energy directors to provide approximately uniform power distribution or current density through a target tissue volume or plane causing the tissue volume to become hemostatic. The spacing among the channels of the energy director guide varies according to the total number of energy directors received in the energy director guide so that relative spacing among the center-most channels is largest and relative spacing among the end-most channels is smallest. The energy director guide secures a selected position of each of the energy directors in the target tissue volume.
    • 描述了组织消融系统,其产生凝固组织的均匀的无血管平面,以帮助来自各种器官的各种生物组织的无血或近无血的切除。 组织消融系统包括能量导向器引导件和两组或多组双极能量引导器。 能量导向器引导件包括一系列通道,其配置能量导向器以通过使组织体积变得止血的目标组织体积或平面提供近似均匀的功率分布或电流密度。 能量导向器引导件的通道之间的间隔根据能量导向器引导器中接收到的能量导向器的总数而变化,使得最中心的通道之间的相对间隔最大,并且最终通道之间的相对间隔最小。 能量导向器引导件将每个能量引导器的选定位置固定在目标组织体积中。
