AI总结:

针对现有手术机器人准确度、精度和自由度不足的问题,设计并制造了一种新型眼内手术机器人系统,通过OCT系统评估,其工具尖端定位准确度达0.053±0.031 mm,并在OCT引导的自动化白内障手术中验证了整体性能。

摘要:

尽管机器人系统在白内障和玻璃体视网膜手术中已有广泛展示,但现有技术或机制在手术过程中的器械操作或潜在的自动化工具更换方面,仍缺乏足够的准确度、精度和自由度。因此,设计并制造了一种新的机器人系统,重点改进工具尖端准确度、跟踪性能以及平滑的器械更换机制。使用光学相干断层扫描(OCT)系统对其工具尖端准确度、精度以及通过远端运动中心维持小切口的机械能力进行了外部评估。通过机器人校准和精确的坐标配准,工具尖端定位的准确度测量为0.053±0.031 mm,并且整体性能在OCT引导的自动化白内障晶状体摘除手术中得到了展示,该手术结合了基于深度学习的术前解剖建模和实时监督。

英文摘要:

Despite the extensive demonstration of robotic systems for both cataract and vitreoretinal procedures, existing technologies or mechanisms still possess insufficient accuracy, precision, and degrees of freedom for instrument manipulation or potentially automated tool exchange during surgical procedures. A new robotic system that focuses on improving tooltip accuracy, tracking performance, and smooth instrument exchange mechanism is therefore designed and manufactured. Its tooltip accuracy, precision, and mechanical capability of maintaining small incision through remote center of motion were externally evaluated using an optical coherence tomography (OCT) system. Through robot calibration and precise coordinate registration, the accuracy of tooltip positioning was measured to be 0.053$\pm$0.031 mm, and the overall performance was demonstrated on an OCT-guided automated cataract lens extraction procedure with deep learning-based pre-operative anatomical modeling and real-time supervision.
