背景：微创外科技术使外科医生暴露在各种职业危害中，这些职业危害可能会促进肌肉骨骼疾病。用于微创手术的远程机器人系统可能有助于减轻这些压力。本研究的目的是比较手动和远程机器人内窥镜手术在姿势和精神压力方面的差异。方法：13名没有内窥镜手术主刀经验的参与者使用两种不同的技术--远程机器人主从式系统和手动内窥镜手术系统--执行了一组模拟手术任务。这些任务包括让一个柔软的球形物体穿过一系列平行的环，沿着一条5厘米长的线缝合，穿一条32英寸的丝带，以及插管。工作紧张指数(JSI)和快速上肢评估(RULA)被用来量化上肢对姿势和力量危险因素的暴露。任务持续时间以秒为单位进行量化。结果：遥控机器人在四项任务中的JSI和RULA得分均显著低于手工操作。远程机器人的任务持续时间显著长于人工任务。参与者报告说，远程机器人技术与手动技术一样直观，但并不比手动技术更有压力。结论：在相同的任务下，使用远程机器人技术比使用手动技术完成任务的时间更长。对于实验室环境下给定的模拟任务，上肢姿势分析得分较高，表明远程机器人手术为外科医生提供了更舒适的环境，而不会产生任何额外的精神压力。
Background: Minimally invasive surgical techniques expose surgeons to a variety of occupational hazards that may promote musculoskeletal disorders. Telerobotic systems for minimally invasive surgery may help to reduce these stressors. The objective of this study was to compare manual and telerobotic endoscopic surgery in terms of postural and mental stress.Methods: Thirteen participants with no experience as primary surgeons in endoscopic surgery performed a set of simulated surgical tasks using two different techniques - a telerobotic master - slave system and a manual endoscopic surgery system. The tasks consisted of passing a soft spherical object through a series of parallel rings, suturing along a line 5 -cm long, running a 32-in ribbon, and cannulation. The Job Strain Index (JSI) and Rapid Upper Limb Assessment (RULA) were used to quantify upper extremity exposure to postural and force risk factors. Task duration was quantified in seconds. A questionnaire provided measures of the participants' intuitiveness and mental stress.Results: The JSI and RULA scores for all four tasks were significantly lower for the telerobotic technique than for the manual one. Task duration was significantly longer for telerobotic than for manual tasks. Participants reported that the telerobotic technique was as intuitive as, and no more stressful than, the manual technique.Conclusions: Given identical tasks, the time to completion is longer using the telerobotic technique than its manual counterpart. For the given simulated tasks in the laboratory setting, the better scores for the upper extremity postural analysis indicate that telerobotic surgery provides a more comfortable environment for the surgeon without any additional mental stress.
