一種新型射頻(RF)消融系統(tǒng)能夠?yàn)椴荒芮谐贿m合手術(shù)的肝臟腫瘤患者提供一種微創(chuàng)治療方法。

Cool-tip系統(tǒng)是由Valleylab公司(Boulder, CO, USA)制造的，該公司是Tyco醫(yī)療保健集團(tuán)(Mansfield, MA, USA)的分支，綜合了一種微處理器為基礎(chǔ)的RF發(fā)生器，通過(guò)17量規(guī)的內(nèi)部冷針頭電極將200瓦RF能量直接輸送到腫瘤。使用CT或者超聲等影像學(xué)技術(shù)，引導(dǎo)針頭到消融部位。在消融過(guò)程中，使用水在內(nèi)部循環(huán)以冷卻相鄰組織，從而能夠輸送最大RF能量，在最短時(shí)間內(nèi)達(dá)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.
