背景机器人手术改善了微创干预。然而，确定内窥镜控制的最佳增益设置具有挑战性。为外科医生提供以适当速度操纵内窥镜的能力将可能通过减轻外科医生的压力来改善手术。在这项研究中，我们验证了增益调节方法的可行性，其中测量操作者的大脑活动并用于评估压力水平。方法我们开发了一种内窥镜操作模拟器，并使用功能性近红外光谱来测量前额皮质活动，而参与者在不同的增益值下控制模拟器。结果前额皮质的大脑激活水平在不同视点运动增益条件下表现出显着差异。结论在特定增益下，与压力相关的大脑活动显着减少，表明大脑活动评估将有助于确定与操作者的感受相关的参数。
BackgroundRobotic surgery improves minimally invasive interventions. However, it is challenging to determine the best gain settings for control of the endoscope. Providing the surgeon with the ability to manipulate the endoscope at an appropriate speed will likely improve the surgery by reducing the surgeon's stress. In this study, we validated the feasibility of a gain‐tuning method in which the operator's brain activity is measured and used to evaluate stress levels.MethodsWe developed an endoscope‐manipulation simulator and used functional near‐infrared spectroscopy to measure the prefrontal cortical activity, while participants controlled the simulator at different gain values.ResultsThe brain activation levels in the prefrontal cortex exhibited significant differences under different viewpoint motion gain conditions.ConclusionsThe stress‐related brain activity was significantly reduced at specific gains, indicating that the brain activity evaluation would be useful to determine the parameters related to the operator's feelings.
