摘要:

在成人腹腔镜手术中,由于机器人工具提供的灵活性增加,机器人辅助手术在全球数千个手术室中成为现实。许多机器人和机器人控制技术已经被开发出来,以帮助更具挑战性的场景,如儿科手术和显微手术。然而,针对具体情况的解决方案的流行,特别是那些专注于非冗余机器人的解决方案,降低了在更具挑战性的场景中初始结果的可重复性。在本文中,我们提出了一个通用的框架,控制手术机器人在约束条件下的遥操作,无论机器人的几何形状。我们的技术分为从侧约束优化算法,它提供虚拟夹具,并与主侧笛卡尔阻抗提供力反馈。两个机器人系统,一个冗余和一个非冗余的实验表明,顺利的遥操作可以实现成人腹腔镜手术和婴儿手术。

英文摘要:

In adult laparoscopy, robot-aided surgery is a reality in thousands of operating rooms worldwide, owing to the increased dexterity provided by the robotic tools. Many robots and robot control techniques have been developed to aid in more challenging scenarios, such as pediatric surgery and microsurgery. However, the prevalence of case-specific solutions, particularly those focused on non-redundant robots, reduces the reproducibility of the initial results in more challenging scenarios. In this paper, we propose a general framework for the control of surgical robotics in constrained workspaces under teleoperation, regardless of the robot geometry. Our technique is divided into a slave-side constrained optimization algorithm, which provides virtual fixtures, and with Cartesian impedance on the master side to provide force feedback. Experiments with two robotic systems, one redundant and one non-redundant, show that smooth teleoperation can be achieved in adult laparoscopy and infant surgery.
