Though several simulators and training methods are available for basic laparoscopic skills, few have addressed force-based skills. In this work, we discuss a haptic simulator that renders virtual materials of different stiffness profiles to be used for haptic skills differentiation. A force-based task was designed on the simulator and the performance of surgeons and novices was analyzed. Results indicate that surgeons and novices differ in their ability to use the haptic device to reproduce target stiffness levels. This work provides an important step towards quantifying haptic skill metrics for the design of surgical skills training simulators.
尽管有几种模拟器和训练方法可用于基础腹腔镜技能，但很少有涉及基于力的技能。在这项工作中，我们讨论了一种触觉模拟器，它能呈现不同刚度分布的虚拟材料，用于触觉技能区分。在模拟器上设计了一项基于力的任务，并分析了外科医生和新手的表现。结果表明，外科医生和新手在使用触觉设备再现目标刚度水平的能力上存在差异。这项工作为量化外科手术技能训练模拟器设计中的触觉技能指标迈出了重要一步。
