Conventional articulating instruments for laparoendoscopic single-site (LESS) surgery have three major drawbacks: Weak articulating force, internal and external crowding, and mirror imaging and motion. The RoboHand™ is a recently developed novel articulating instrument. The goal of its development was to minimize the abovementioned three major drawbacks. In an ex vivo test, the joint force of the RoboHand was 2.5 to 3 times stronger than that of the LaparoAngle™ or the SILS™ instrument. In the porcine nephrectomy model, the operative times in the RoboHand group (28.8±6.6 min) were shorter than those in the LaparoAngle group (39.7±5.4 min), although not significant (P=0.146). The RoboHand prototype seems to be superior to other articulating laparoscopic instruments in its mechanical properties, such as joint force, and not to be clinically inferior to LaparoAngle for LESS. We describe the techniques for using this innovative instrument and discuss its advantages.
传统的腹腔镜单部位手术（LESS）器械有三个主要缺点：关节力弱、内外拥挤和镜像成像及运动。RoboHand™ 是一种新开发的新型关节器械。其开发的目的是最大限度地减少上述三个主要缺点。在一项离体测试中，RoboHand 的关节力比 LaparoAngle™ 或 SILS™ 器械强 2.5 至 3 倍。在猪肾切除术模型中，RoboHand 组的手术时间（28.8±6.6min）比 LaparoAngle 组（39.7±5.4min）短，但无统计学意义（P=0.146）。RoboHand 原型在机械性能方面优于其他关节腹腔镜器械，例如关节力，在 LESS 方面并不逊于 LaparoAngle。我们介绍了使用这种创新器械的技术，并讨论了它的优势。
