This study examines the advantages and disadvantages of a commercial telemanipulator system (daVinci, Intuitive Surgical, USA) with computer-guided instruments in functional endoscopic sinus surgery (FESS).
We performed five different surgical FESS steps on 14 anatomical preparation and compared them with conventional FESS. A total of 140 procedures were examined taking into account the following parameters: degrees of freedom (DOF), duration , learning curve, force feedback, human-machine-interface.
Telemanipulatory instruments have more DOF available then conventional instrumentation in FESS. The average time consumed by configuration of the telemanipulator is around 9+/-2 min. Missing force feedback is evaluated mainly as a disadvantage of the telemanipulator. Scaling was evaluated as helpful. The ergonomic concept seems to be better than the conventional solution.
Computer guided instruments showed better results for the available DOF of the instruments. The human-machine-interface is more adaptable and variable then in conventional instrumentation. Motion scaling and indexing are characteristics of the telemanipulator concept which are helpful for FESS in our study.
本研究探讨了一款带有计算机引导器械的商用远程操作手术系统（美国直观外科公司的达芬奇手术系统）在功能性鼻内镜鼻窦手术（FESS）中的优缺点。
我们在14个解剖标本上进行了5种不同的FESS手术步骤，并将其与传统FESS进行比较。共检查了140例手术，考虑了以下参数：自由度（DOF）、持续时间、学习曲线、力反馈、人机界面。
在FESS中，远程操作器械比传统器械具有更多的可用自由度。远程操作器配置的平均耗时约为9±2分钟。缺少力反馈主要被视为远程操作器的一个缺点。缩放被认为是有帮助的。人体工程学概念似乎比传统解决方案更好。
计算机引导器械在器械的可用自由度方面显示出更好的效果。人机界面比传统器械更具适应性和可变性。运动缩放和索引是远程操作器概念的特点，在我们的研究中对FESS有帮助。
