Computer vision (CV) feedback could be aimed as a constant tutor to guide ones proficiency during microsurgical practice in controlled environments. Five neurosurgeons with different levels of microsurgical expertise performed simulated vessel dissection and micro-suture in an ex vivo model for posterior computer analysis of recorded videos. A computer program called PRIME (Proficiency Index of Microsurgical Education) used in this research recognized color-labeled surgical instruments, from downloading videos into a platform, with a range of motion greater than 3 mm, for objective evaluation of number of right and left hand movements. A proficiency index of 0 to 1 was pre-established in order to evaluate continuous training improvement. PRIME computer program captured all hand movements executed by participants, except for small tremors or inconsistencies that have a range of motion inferior to 3 mm. Number of left and right hand movements were graphically expressed in order to guide more objective and efficacious training for each trainee, without requiring body sensors and cameras around the operating table. Participants with previous microsurgical experience showed improvement from 0.2 to 0.6 (p < 0.05), while novices had no improvement. Proficiency index set by CV was suggested, in a self-challenge and self-coaching manner. PRIME would offer the capability of constant laboratory microsurgical practice feedback under CV guidance, opening a new window for oriented training without a tutor or specific apparatus regarding all levels of microsurgical proficiency. Prospective, large data study is needed to confirm this hypothesis.
计算机视觉 (CV) 反馈可以作为一个持续的导师，在受控环境中指导外科医生进行显微手术练习。五位具有不同显微手术专业水平的神经外科医生在一个体外模型中进行了模拟血管解剖和微缝合，然后对记录的视频进行了后处理的计算机分析。本研究中使用的名为 PRIME（显微手术教育熟练度指数）的计算机程序可以识别带颜色标记的手术器械，从下载视频到平台，只要运动范围大于 3 毫米，就可以对左右手运动的数量进行客观评估。为了评估连续培训的效果，预先设定了 0 到 1 的熟练度指数。PRIME 计算机程序可以捕获参与者执行的所有手部动作，但不包括运动范围小于 3 毫米的小震颤或不一致的动作。左右手部运动的数量以图形方式表示，以便为每个受训者提供更客观、更有效的训练，而无需在手术台周围安装身体传感器和摄像头。有显微手术经验的参与者的熟练度从 0.2 提高到 0.6（p < 0.05），而新手没有提高。建议使用 CV 设置熟练度指数，以自我挑战和自我指导的方式进行。PRIME 将提供在 CV 指导下进行持续实验室显微手术练习反馈的能力，为所有显微手术熟练度水平的定向培训开辟了一个新窗口，无需导师或特定设备。需要进行前瞻性、大数据研究来验证这一假设。
