Computed tomography (CT)-compatible robots, both commercial and research-based, have been developed with the intention of increasing the accuracy of needle placement and potentially improving the outcomes of therapies in addition to reducing clinical staff and patient exposure to radiation during CT fluoroscopy. In the case of highly inaccessible lesions that require multiple plane angulations, robotically assisted needles may improve biopsy access and targeted drug delivery therapy by avoidance of the straight line path of normal linear needles.
We report our preliminary experience of performing radiofrequency ablation of the liver using a robotic-assisted CT guidance system on 11 patients (17 lesions).
RESULTS/CONCLUSION: Robotic-assisted planning and needle placement appears to have high accuracy, is technically easier than the non-robotic-assisted procedure, and involves a significantly lower radiation dose to both patient and support staff.
• An early experience of robotic-assisted radiofrequency ablation is reported • Robotic-assisted RFA improves accuracy of hepatic lesion targeting • Robotic-assisted RFA makes the procedure technically easier with significant lower radiation dose.
为了提高在 CT 透视下进行介入治疗时的精确度，并减少医护人员和患者所受的辐射，开发出了商用和研究用的 CT 兼容机器人。在需要多平面角度的难以触及的病灶中，机器人辅助的穿刺针可以通过避免普通直线穿刺针的直线路径来改善活检的可达性和靶向药物输送治疗。
我们报告了在 11 例（17 个病灶）患者中使用机器人辅助 CT 引导系统进行射频消融治疗的初步经验。
结果/结论：机器人辅助的规划和置针似乎具有很高的准确性，比非机器人辅助的程序更容易操作，并且患者和支持人员的辐射剂量显著降低。
• 报告了机器人辅助射频消融的早期经验。• 机器人辅助 RFA 提高了肝病灶靶向的准确性。• 机器人辅助 RFA 使操作更简单，辐射剂量显著降低。
