OBJECT
The purpose of this study was to evaluate the accuracy of ventriculostomy catheter placement on a head- and hand-tracked high-resolution and high-performance virtual reality and haptic technology workstation.
METHODS
Seventy-eight fellows and residents performed simulated ventriculostomy catheter placement on an ImmersiveTouch system. The virtual catheter was placed into a virtual patient's head derived from a computed tomography data set. Participants were allowed one attempt each. The distance from the tip of the catheter to the Monro foramen was measured.
RESULTS
The mean distance (+/- standard deviation) from the final position of the catheter tip to the Monro foramen was 16.09 mm (+/- 7.85 mm).
CONCLUSIONS
The accuracy of virtual ventriculostomy catheter placement achieved by participants using the simulator is comparable to the accuracy reported in a recent retrospective evaluation of free-hand ventriculostomy placements in which the mean distance from the catheter tip to the Monro foramen was 16 mm (+/- 9.6 mm).
目的
本研究旨在评估在头部和手部跟踪的高分辨率高性能虚拟现实和触觉技术工作站上进行脑室造瘘管置入的准确性。
方法
78名研究员和住院医师在沉浸式触摸系统上进行了模拟脑室造瘘管置入操作。将虚拟导管放置到源自计算机断层扫描数据集的虚拟患者头部中。参与者每人允许尝试一次。测量导管尖端到孟氏孔的距离。
结果
导管尖端最终位置到孟氏孔的平均距离（±标准差）为16.09毫米（±7.85毫米）。
结论
参与者使用模拟器实现的虚拟脑室造瘘管置入的准确性与最近一项对徒手脑室造瘘管置入的回顾性评估中报告的准确性相当，在该评估中，导管尖端到孟氏孔的平均距离为16毫米（±9.6毫米）。
