机器人手术提供了许多好处，如减少侵入性和增加灵活性。这是以外科医生和患者之间没有直接接触为代价的。这种物理分离阻止了外科医生对组织和器官进行直接触觉探索，从而完全依赖于视觉提示。目前的技术还不能测量和再现真实和完整的触觉（交互力、温度、粗糙度等）。在本文中，我们提出了一个多模态反馈的基础上的概念，包括不同种类的视觉和触觉的线索与力反馈，可以潜在地提高外科医生的性能和病人的安全的集成。我们提出了一个具有成本效益的触觉显示器模拟脉动动脉，已被集成到触觉工作站联合收割机结合触觉和力反馈信息。此外，我们研究了不同的反馈类型，包括触觉和/或视觉线索，对受试者执行两个典型触诊任务的表现的影响：（1）探索组织以找到隐藏的动脉和（2）识别隐藏的动脉的方向。结果表明，增加触觉反馈显着减少任务完成时间。此外，对于高难度水平，受试者表现更好的反馈条件结合触觉和视觉线索。事实上，研究中的大多数受试者更喜欢这种组合反馈，因为冗余反馈使受试者在行动中放心。基于这项工作，我们可以推断，多模态触觉反馈提高了受试者的性能和信心，在探索程序。
Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient. This physical separation prevents surgeons from performing direct haptic exploration of tissues and organs, imposing exclusive reliance on visual cues. Current technology is not yet able to both measure and reproduce a realistic and complete sense of touch (interaction force, temperature, roughness, etc.). In this paper, we put forward a concept based on multimodal feedback consisting of the integration of different kinds of visual and tactile cues with force feedback that can potentially improve both the surgeon's performance and the patient's safety. We present a cost-effective tactile display simulating a pulsating artery that has been integrated into a haptic workstation to combine both tactile and force-feedback information. Furthermore, we investigate the effect of different feedback types, including tactile and/or visual cues, on the performance of subjects carrying out two typical palpation tasks: (1) exploring a tissue to find a hidden artery and (2) identifying the orientation of a hidden artery. The results show that adding tactile feedback significantly reduces task completion time. Moreover, for high difficulty levels, subjects perform better with the feedback condition combining tactile and visual cues. As a matter of fact, the majority of the subjects in the study preferred this combined feedback because redundant feedback reassures subjects in their actions. Based on this work, we can infer that multimodal haptic feedback improves subjects' performance and confidence during exploratory procedures.
