Radiofrequecy ablation is the most widely used local ablative therapy for both primary and metastatic liver tumours. However, it has limited application in the treatment of large tumours (tumours >3cm) and multicentric tumours. In recent years, many strategies have been developed to extend the application of radiofrequency ablation to large tumours. A promising approach is to take advantage of the rapid advancement in imaging and robotic technologies to construct an integrated surgical navigation and medical robotic system. This paper presents a review of existing surgical navigation methods and medical robots. We also introduce our current developed model - Transcutaneous Robot-assisted Ablation-device Insertion Navigation System (TRAINS). The clinical viability of this prototyped integrated navigation and robotic system for large and multicentric tumors is demonstrated using animal experiments.
射频消融是治疗原发性和转移性肝肿瘤最广泛应用的局部消融疗法。然而，它在治疗大肿瘤（肿瘤＞3cm）和多中心肿瘤方面的应用有限。近年来，已经开发出许多策略来扩展射频消融在大肿瘤中的应用。一种很有前途的方法是利用成像和机器人技术的快速发展，构建一个集成的手术导航和医疗机器人系统。本文综述了现有的手术导航方法和医疗机器人。我们还介绍了我们目前开发的模型——经皮机器人辅助消融器械插入导航系统（TRAINS）。通过动物实验证明了该原型集成导航和机器人系统在大肿瘤和多中心肿瘤中的临床可行性。
