Abstract：
UNASSIGNED: An exoscope heralds a new era of optics in surgery. However, there is limited quantitative evidence describing and comparing the learning curve.
UNASSIGNED: This study aimed to investigate the learning curve, plateau, and rate of novice surgeons using an Olympus ORBEYE exoscope compared to an operating microscope (Carl Zeiss OPMI PENTERO or KINEVO 900).
UNASSIGNED: A preclinical, randomized, crossover, noninferiority trial assessed the performance of seventeen novice and seven expert surgeons completing the microsurgical grape dissection task \"Star\'s the limit.\" A standardized star was drawn on a grape using a stencil with a 5 mm edge length. Participants cut the star and peeled the star-shaped skin off the grape with microscissors and forceps while minimizing damage to the grape flesh. Participants repeated the task 20 times consecutively for each optical device. Learning was assessed using model functions such as the Weibull function, and the cognitive workload was assessed with the NASA Task Load Index (NASA-TLX).
UNASSIGNED: Seventeen novice (male:female 12:5; median years of training 0.4 [0-2.8 years]) and six expert (male:female 4:2; median years of training 10 [8.9-24 years]) surgeons were recruited. \"Star\'s the limit\" was validated using a performance score that gave a threshold of expert performance of 70 (0-100). The learning rate (ORBEYE -0.94 ± 0.37; microscope -1.30 ± 0.46) and learning plateau (ORBEYE 64.89 ± 8.81; microscope 65.93 ± 9.44) of the ORBEYE were significantly noninferior compared to those of the microscope group (p = 0.009; p = 0.027, respectively). The cognitive workload on NASA-TLX was higher for the ORBEYE. Novices preferred the freedom of movement and ergonomics of the ORBEYE but preferred the visualization of the microscope.
UNASSIGNED: This is the first study to quantify the ORBEYE learning curve and the first randomized controlled trial to compare the ORBEYE learning curve to that of the microscope. The plateau performance and learning rate of the ORBEYE are significantly noninferior to those of the microscope in a preclinical grape dissection task. This study also supports the ergonomics of the ORBEYE as reported in preliminary observational studies and highlights visualization as a focus for further development.

摘要：
■外镜预示着外科光学的新时代。然而,描述和比较学习曲线的定量证据有限。
■本研究旨在研究学习曲线，高原,与手术显微镜（卡尔蔡司OPMIPENTERO或KINEVO900）相比，使用OlympusORBEYE出镜的新手外科医生的比率。
■临床前，随机化，交叉，非劣效性试验评估了17名新手和7名专家外科医生完成显微外科葡萄解剖任务的表现。“使用边缘长度为5毫米的模板在葡萄上绘制了标准化的星星。参与者用微型剪刀和镊子将星形的皮肤从葡萄上切下，同时将对葡萄肉的损害降至最低。参与者为每个光学设备连续重复该任务20次。使用Weibull函数等模型函数评估学习，认知工作量采用NASA任务负荷指数(NASA-TLX)进行评估。
■招募了17名新手（男性：女性12:5；平均训练年限0.4[0-2.8年]）和6名专家（男性：女性4:2；平均训练年限10[8.9-24年]）的外科医生。“Star'sthelimit”已使用性能评分进行验证，该评分使专家性能的阈值为70（0-100）。与显微镜组相比，ORBEYE的学习率（ORBEYE-0.94±0.37；显微镜-1.30±0.46）和学习平台（ORBEYE64.89±8.81；显微镜65.93±9.44）明显不差（分别为p=0.009；p=0.027）。对于ORBEYE，NASA-TLX的认知工作量更高。新手更喜欢ORBEYE的运动自由和人体工程学，但更喜欢显微镜的可视化。
■这是第一个量化ORBEYE学习曲线的研究，也是第一个将ORBEYE学习曲线与显微镜学习曲线进行比较的随机对照试验。在临床前葡萄解剖任务中，ORBEYE的高原性能和学习率明显不劣于显微镜。这项研究还支持了初步观察研究中报道的ORBEYE的人体工程学，并强调了可视化作为进一步开发的重点。
