目的：概念直观书写界面（IWI）在机器人辅助激光腹腔镜手术中的可行性先前已得到证实。本文通过比较传统手法（CM）和IWI手法（IM）并进行动物实验，探讨IWI的潜在改善作用。材料和方法：设计了三个任务，被认为是激光腹腔镜外科手术的代表。所有测试参与者在所有任务中都使用CM和IM。以每个任务的完成时间和错误水平作为比较指标，并将其整合到自定义的时间和错误指数（ITE）中。进行了六次连续的体外试验以研究学习曲线。此外，通过在机器人辅助激光腹腔镜手术中使用IWI对兔子进行肾切除术。结果如下：结果表明，IM的显着优势，具有更短的完成时间，更多的成功投篮，并在三个任务中的错误长度较小，相比CM。学习曲线显示了IM的良好趋势。超过一半的参与者在IM中表现更好。动物模型实验证实了IM的临床可行性，但同时也暴露出一些局限性。结论：新的IWI界面通过利用熟悉的书写技能，确实改善了激光腹腔镜手术。由于其实施的灵活性和易用性，IWI在激光腹腔镜手术中具有明显的应用潜力。
Objective: The feasibility of the conceptual Intuitive Writing Interface (IWI) in robot-aided laser laparoscopic surgery has been demonstrated previously. This paper investigates the potential improvement of IWI by comparing conventional manipulation (CM) and IWI manipulation (IM) and conducting an animal experiment. Materials and Methods: Three tasks were designed that were considered to be representative of laser laparoscopic surgical procedures. All test participants used both CM and IM in all tasks. Completion time and error level of each task were taken as comparative indices and were integrated into a self-defined Index of Time and Error (ITE). Six sequential in vitro trials were carried out to investigate learning curves. In addition, nephrectomy was performed on a rabbit by employing IWI in robot-aided laser laparoscopic surgery. Results: The results showed significant advantages for IM, with shorter completion time, more successful shots, and smaller error length in the three tasks, as compared to CM. The learning curve showed a promising trend for IM. More than half of the participants performed better with IM. The animal model experiment demonstrated the clinical feasibility of IM, but at the same time revealed some limitations. Conclusions: The new IWI interface definitely improved laser laparoscopic procedures by taking advantage of familiar writing skills. With its flexibility of implementation and ease of use, IWI has clear potential for use in laser laparoscopic procedures.
