摘要
新闻编辑从发明人提供的背景信息中获得了以下引文：“机器人外科是本领域众所周知的，机器人技术在脊柱外科手术中的应用也是众所周知的。许多机器人外科系统，例如来自直观外科的达芬奇机器人外科系统，都是遥操作的。多臂机器人外科系统可在本领域获得，例如Cambridge Medical Robotics提供的那些，但这些已知的系统通常也是远程操作的，并且是由单独部署的单臂组成的LL，并且由远程定位的控制单元提供某种程度的协调。包括多个手推车上的多臂的系统在集成到Surgica L工作流程方面有很大的缺点，以及在手术室中不受欢迎的大空间。在这些多臂系统确实使用单个手推车的情况下，两臂之间的协调仍然由医生完成，医生坐在控制单元中，用眼睛和手“闭合回路”。此外，通过远程定位的控制单元对TEL操作单元的控制不能提供全范围手术程序所需的控制水平，特别是在脊柱手术的情况下。精度将不可避免地低于所有机械臂固定在包括控制单元的单一底盘上并由其协调的系统。
Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Robotic surgery is well known in the art, as is the application of robotic techniques to spinal surgery procedures such as pedi cle screw placement. Many robotic surgery systems, such as the da Vinci robotic surgery system from Intuitive Surgical, are teleoperated. Multi-arm robotic surg ical systems are available in the field, for example those provided by Cambridge Medical Robotics, but these known systems are often also teleoperated and are a ll comprised of single arms deployed separately with some level of coordination provided by a remotely-positioned control unit. Systems comprising multiple arms on multiple carts have significant drawbacks regarding integration into surgica l workflow, along with an undesirably large footprint in the operating room. Als o, in cases where these multi-arm systems do utilize a single cart, still the co ordination between the arms is done by a physician who “closes the loop” with hi s eyes and hands while he sits in the control unit. Moreover, the control of tel eoperated units by a remotely-positioned control unit does not provide the level of control required for a full range of surgical procedures, particularly in th e case of spinal surgery. Accuracy will inevitably be inferior to a system where all robotic arms are fixed to, and coordinated by, a single chassis comprising a control unit.
