目的：泌尿外科复杂的腹腔镜手术技术要求高，学习曲线长。机器人系统显着增加了腹腔镜手术的成本。因此，我们评估了机械操纵器 Radius 手术系统 (RSS) 在泌尿科复杂腹腔镜手术中的使用情况。 材料和方法：RSS (Tuebingen Scientific) 由两个手动手术操纵器组成，并提供可偏转和可旋转的尖端，可实现六个自由度。我们通过使用盆腔训练器中的一系列标准化模型来评估该系统。我们分析了系统的有效性和学习曲线。然后，我们在腹腔镜根治性前列腺切除术的临床环境中评估了该系统。结果：将具有 RSS 经验的外科医生与没有该系统经验的外科医生进行了比较。我们确定了那些没有系统经验的参与者仅在骨盆训练器中进行完整吻合时的学习曲线。然而，该学习曲线包括不到 10 次吻合。腹腔镜腹膜外手术的首次临床经验。根治性前列腺切除术（n = 10）是有希望的。所有吻合术均在术后 8 天进行常规（X 射线）检查。结论：RSS 系统易于使用，我们发现学习曲线非常短。我们现在优化该系统以用于泌尿外科。该装置可以方便复杂的腹腔镜手术，而无需。使用昂贵的机器人系统，应该在实验和临床环境中进一步评估。 (c) 2006 年欧洲泌尿外科协会。由 Elsevier B.V. 出版。保留所有权利。
Objective: Complex laparoscopic procedures in urology are technically demanding with an extended learning curve. Robotic systems add significant cost to laparoscopic procedures. We therefore evaluated the use of the Radius Surgical System (RSS), a mechanical manipulator, for complex laparoscopic cases in urology.Material and methods: The RSS (Tuebingen Scientific) consists of two hand-guided surgical manipulators and provides a deflectable and rotatable tip allowing six degrees of freedom. We evaluated the system by using a series of standardized models in the pelvitrainer. We analyzed the effectiveness of the system and the learning curve. We then evaluated the system in the clinical setting during laparoscopic radical prostatectomy.Results: Surgeons with experience on the RSS were compared to surgeons without previous experience on the system. We identified a learning curve in those participants without experience on the system only when performing complete anastomoses in the pelvitrainer. However, this learning curve included less than 10 anastomoses. The first clinical experiences during laparoscopic extraperitoneal. radical prostatectomy (n = 10) are promising. All anastomoses were patent on routine (X-ray) examination 8 days after surgery.Conclusions: The RSS system is easy to use and we identified a very short learning curve. We now optimize the system for use in urology. This device may facilitate complex laparoscopic procedures without. the use of costly robotic systems and should be further evaluated in the experimental and clinical setting.
