Despite the substantial progress achieved in the development and integration of augmented reality (AR) in surgical robotic and autonomous systems (RAS), the center of focus in most devices remains on improving end-effector dexterity and precision, as well as improved access to minimally invasive surgeries. This paper aims to provide a systematic review of different types of state-of-the-art surgical robotic platforms while identifying areas for technological improvement. We associate specific control features, such as haptic feedback, sensory stimuli, and human-robot collaboration, with AR technology to perform complex surgical interventions for increased user perception of the augmented world. Current researchers in the field have, for long, faced innumerable issues with low accuracy in tool placement around complex trajectories, pose estimation, and difficulty in depth perception during two-dimensional medical imaging. A number of robots described in this review, such as Novarad and SpineAssist, are analyzed in terms of their hardware features, computer vision systems (such as deep learning algorithms), and the clinical relevance of the literature. We attempt to outline the shortcomings in current optimization algorithms for surgical robots (such as YOLO and LTSM) whilst providing mitigating solutions to internal tool-to-organ collision detection and image reconstruction. The accuracy of results in robot end-effector collisions and reduced occlusion remain promising within the scope of our research, validating the propositions made for the surgical clearance of ever-expanding AR technology in the future.
尽管在手术机器人和自主系统(RAS)中增强现实(AR)的开发和集成方面取得了重大进展,但大多数设备的关注焦点仍然在于提高末端执行器的灵活性和精度,以及改善微创手术的可及性。本文旨在对不同类型的最先进手术机器人平台进行系统综述,同时确定技术改进的领域。我们将特定的控制特征(如触觉反馈、感官刺激和人机协作)与 AR 技术相关联,以执行复杂的手术干预,从而提高用户对增强世界的感知。该领域的当前研究人员长期以来一直面临着许多问题,例如在复杂轨迹、姿势估计和二维医学成像中的深度感知方面,工具放置的精度低。本文分析了许多机器人,例如 Novarad 和 SpineAssist,从硬件特性、计算机视觉系统(如深度学习算法)以及文献的临床相关性方面进行了分析。我们试图概述手术机器人中当前优化算法的缺点(例如 YOLO 和 LTSM),同时为内部工具-器官碰撞检测和图像重建提供缓解方案。在我们的研究范围内,机器人末端执行器碰撞和减少遮挡的结果准确性仍然很有前途,验证了在未来不断扩展的 AR 技术的手术清除方面提出的主张。
