The ISG viewing wand is an intra-operative guidance system with a proprioceptive robotic-like jointed arm. It provides surgeons with almost instantaneously reconstructed computer-generated CT or MRI images in two or three dimensions and can correlate any point within the operative field to its corresponding locus on the reformatted scan images. In addition to having been used in over 400 neurosurgical patients in Bristol, 14 patients with skull-base, cerebello-pontine angle or temporal bone lesions have also undergone wand-guided resections. The wand has proved to be particularly useful in pre-operative planning, allowing minimally-invasive incisions, providing per-operative navigation, identifying the relationship and proximity of important anatomical structures and in assessing the extent of lesion resection. We illustrate the advantages of intra-operative image-guidance by discussing four cases. The potential applications of this form of imaging technology to other otolaryngological procedures are discussed.
ISG 观察棒是一种带有本体感觉机器人式关节臂的术中引导系统。它能为外科医生几乎即时重建二维或三维计算机生成的 CT 或 MRI 图像，并可将术野内的任何一点与其在重新格式化扫描图像上的对应位置相关联。除了在布里斯托尔已应用于 400 多名神经外科患者外，14 例患有颅底、桥小脑角或颞骨病变的患者也接受了观察棒引导下的切除术。事实证明，观察棒在术前规划中特别有用，可实现微创切口、提供术中导航、确定重要解剖结构的关系和邻近程度以及评估病变切除范围。我们通过讨论四个病例来说明术中图像引导的优势。还讨论了这种成像技术在其他耳鼻喉科手术中的潜在应用。
