Abstract

Laparoscopic surgery brings substantial benefits to patients. However, it remains challenging for surgeons because of motion constraints and perception limitations. Notably, the perception of interactions with organs is largely compromised. This paper evaluates the effectiveness of a forearm-based skin-stretch haptic feedback system rendering surgical tool tip force. Twenty novice participants had to discern the stiffness of samples to investigate stiffness perception in a simulated laparoscopic task. The experimental protocol involved manipulating samples with three difficulty levels and testing three feedback conditions: no augmentation, visual feedback, and tactile feedback. The results demonstrate that feedback significantly enhances the success rate of laparoscopic palpation tasks. The proposed tactile feedback boosts confidence and task speed and reduces peak force and perceived workload. These benefits become even more pronounced when difficulty increases. These promising findings affirm the value of skin-stretch haptic feedback augmentation in improving performance for simulated laparoscopy tasks, paving the way for more integrated and deployable devices for the operating room.

皮肤拉伸触觉反馈增强技术提高了模拟腹腔镜触诊任务中的表现。

腹腔镜手术为患者带来了巨大的益处。然而，由于运动的限制和感知的局限性，腹腔镜手术对外科医生来说仍然具有挑战性。值得注意的是，与器官互动的感知在很大程度上受到了影响。本文评估了基于前臂的皮肤拉伸触觉反馈系统呈现手术工具尖端力的有效性。20 名新手参与者必须辨别样本的硬度，以研究模拟腹腔镜任务中的硬度感知。实验方案包括操作三个难度级别的样本和测试三种反馈条件：无增强、视觉反馈和触觉反馈。结果表明，反馈能显著提高腹腔镜触诊任务的成功率。建议的触觉反馈增强了信心和任务速度，降低了峰值力和感知工作量。当难度增加时，这些优势会更加明显。这些令人鼓舞的研究结果肯定了皮肤拉伸触觉反馈增强技术在提高模拟腹腔镜检查任务的性能方面所具有的价值，为在手术室中使用更多的集成和可部署设备铺平了道路。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
