立体定向框架是用于神经外科靶向的标准工具，但是对于患者来说是不舒服的并且阻碍手术野。微立体定向框架对于患者来说更舒适，提供更好的手术部位进入，并且作为传统立体定向装置的替代品越来越受欢迎。然而，临床上可用的微立体定向框架需要长时间的制造延迟或昂贵的图像引导系统。我们介绍了一种用于脑深部刺激手术的机器人调节的一次性微立体定向框架，该框架消除了现有微立体定向框架的缺点。我们的框架可以在手术室中使用术前计划在不到五分钟的时间内自动调整。对幻影的验证研究表明，我们的方法提供了0.14 mm的目标定位误差，这超过了脑深部电刺激手术所需的精度。
Stereotactic frames are a standard tool for neurosurgical targeting, but are uncomfortable for patients and obstruct the surgical field. Microstereotactic frames are more comfortable for patients, provide better access to the surgical site, and have grown in popularity as an alternative to traditional stereotactic devices. However, clinically available microstereotactic frames require either lengthy manufacturing delays or expensive image guidance systems. We introduce a robotically-adjusted, disposable microstereotactic frame for deep brain stimulation surgery that eliminates the drawbacks of existing microstereotactic frames. Our frame can be automatically adjusted in the operating room using a preoperative plan in less than five minutes. A validation study on phantoms shows that our approach provides a target positioning error of 0.14 mm, which exceeds the required accuracy for deep brain stimulation surgery.
