BACKGROUND: Accuracy of needle tip placement and needle tracking in soft tissue are of particular importance in many medical procedures. In recent years, developing autonomous and teleoperated systems for needle insertion has become an active area of research. METHODS: In this study, needle insertion was performed using a master-slave set-up with multi-degrees of freedom. The effect of force feedback on the accuracy of needle insertion was investigated. In addition, this study compared autonomous, teleoperated and semi-autonomous needle insertion. RESULTS: The results of this study show that incorporation of force feedback can improve teleoperated needle insertion. However, autonomous and semi-autonomous needle insertions, which use feedback from a deflection model, provide significantly better performance. CONCLUSIONS: Development of a haptic master-slave needle insertion system, which is capable of performing some autonomous tasks based on feedback from tissue deformation and needle deflection models, can improve the performance of autonomous robotics-based insertions as well as non-autonomous teleoperated manual insertions.
背景:在许多医疗程序中,针尖端位置和针跟踪的准确性尤为重要。近年来,开发用于针插入的自主和远程操作系统已成为一个活跃的研究领域。
方法:在这项研究中,使用具有多自由度的主从设置进行针插入。研究了力反馈对针插入准确性的影响。此外,本研究比较了自主、远程操作和半自动针插入。
结果:本研究的结果表明,结合力反馈可以提高远程操作针插入的准确性。然而,使用来自偏转模型的反馈的自主和半自动针插入提供了显著更好的性能。
结论:开发一种触觉主从式针插入系统,该系统能够根据组织变形和针偏转模型的反馈执行一些自主任务,可以提高基于自主机器人的插入以及非自主远程操作手动插入的性能。
