This study aimed to evaluate surgeons' ergonomic satisfaction when using laparoscopic energy devices and to investigate how prolonged use affects muscle fatigue and surgical performance.
A two-part study, including a survey and a kinesiologic experiment, was conducted to compare 4 laparoscopic energy devices (D1-D4). Thirty surgeons completed a structured survey assessing ergonomic factors such as device weight, grip strength, handle design, comfort, and trigger location. In parallel, a kinesiologic experiment involving 20 surgeons measured device activation force, surface electromyography (EMG) changes, and targeting accuracy before and after fatigue induction using a standardized protocol.
The survey revealed significant ergonomic differences among devices. In the kinesiologic study, two devices showed a significant decline in precision and targeting accuracy after fatigue. All but one device demonstrated significant changes in the median frequency (MDF) and integrated EMG (iEMG) of the flexor digitorum superficialis muscle (P < 0.001), indicating muscle fatigue.
Prolonged use of certain laparoscopic energy devices induces muscle fatigue and impairs accuracy. These findings underscore the importance of ergonomic considerations in surgical instrument design to enhance surgeon performance and reduce fatigue-related risks.
本研究旨在评估外科医生使用腹腔镜能量设备时的人体工程学满意度，并调查长时间使用如何影响肌肉疲劳和手术表现。
进行了一项分为两部分的研究，包括一项调查和一项运动学实验，以比较4种腹腔镜能量设备（D1-D4）。30名外科医生完成了一项结构化调查，评估了诸如设备重量、握力、手柄设计、舒适度和扳机位置等人体工程学因素。同时，一项涉及20名外科医生的运动学实验，使用标准化方案测量了疲劳诱导前后的设备激活力、表面肌电图（EMG）变化和靶向准确性。
调查显示不同设备之间存在显著的人体工程学差异。在运动学研究中，两种设备在疲劳后精度和靶向准确性显著下降。除一种设备外，所有设备的指浅屈肌的中位频率（MDF）和积分肌电图（iEMG）均有显著变化（P < 0.001），表明存在肌肉疲劳。
长时间使用某些腹腔镜能量设备会导致肌肉疲劳并损害准确性。这些发现强调了在手术器械设计中考虑人体工程学的重要性，以提高外科医生的表现并降低与疲劳相关的风险。
