Most conventional computer-aided navigation systems assist the surgeon visually by tracking the position of an ancillary and by superposing this position into the 3D preoperative imaging exam. This paper aims at adding to such navigation systems a device that will guide the surgeon towards the target, following a complex preplanned ancillary trajectory. We propose to use tactile stimuli for such guidance, with the design of a vibrating belt. An experiment using a virtual surgery simulator in the case of skull base surgery is conducted with 9 naïve subjects, assessing the vibrotactile guidance effectiveness for complex trajectories. Comparisons between a visual guidance and a visual+tactile guidance are encouraging, supporting the relevance of such tactile guidance paradigm.
大多数传统的计算机辅助导航系统通过跟踪辅助设备的位置并将该位置叠加到术前三维成像检查中来为外科医生提供视觉辅助。本文旨在为这类导航系统增添一种设备，该设备将沿着复杂的预先规划的辅助轨迹引导外科医生朝向目标。我们建议使用触觉刺激进行这种引导，设计了一种振动带。针对9名未经培训的受试者进行了一项在颅底手术案例中使用虚拟手术模拟器的实验，评估复杂轨迹的振动触觉引导效果。视觉引导和视觉+触觉引导之间的比较结果令人鼓舞，支持了这种触觉引导模式的相关性。
