一种新型射频(RF)消融系统能够为不能切除不适合手术的肝脏肿瘤患者提供一种微创治疗方法。

Cool-tip系统是由Valleylab公司(Boulder, CO, USA)制造的，该公司是Tyco医疗保健集团(Mansfield, MA, USA)的分支，综合了一种微处理器为基础的RF发生器，通过17量规的内部冷针头电极将200瓦RF能量直接输送到肿瘤。使用CT或者超声等影像学技术，引导针头到消融部位。在消融过程中，使用水在内部循环以冷却相邻组织，从而能够输送最大RF能量，在最短时间内达到最大的消融效果。
 
Ablation System for Inoperable Hepatic Tumors
 

 
A new radiofrequency (RF) ablation system offers a minimally invasive alternative for patients with non-resectable hepatic tumors who are not ideal surgical candidates.

The Cool-tip system, manufactured by Valleylab (Boulder, CO, USA), a division of Tyco Healthcare Group (Mansfield, MA, USA), combines a microprocessor-based RF generator with a 17-gauge internally cooled needle electrode to deliver 200 watts of RF energy directly to the tumor. Imaging technology such as computed tomography (CT) or ultrasound is used to guide the needle to the ablation site. Water is circulated internally through the electrode during ablation to cool adjacent tissue, thereby maximizing delivery of RF energy and creating the largest ablation possible in a minimal amount of time.
