This study was done using an educational tool called the "Micro-Clock", which was inspired by Chan's "round-the-clock" training model. The Micro-Clock consisted of a surgical sponge on which 12 sewing needles were configured in the shape of a clock. The subjects were asked to thread a small suture through the eyelets as quickly as possible. Steadiness and instrument manipulation were evaluated during each trial and graded from 1 to 3. The execution time was measured in seconds. Fifteen instructors did the Micro-Clock test once in order to validate this tool's ability to assess the skills of qualified microsurgeons. Next, nine students, who were enrolled in a microsurgery diploma program, did the test nine times during the program to measure their progression and to evaluate their mastery and execution speed. There was no significant differences among the three instructor sub-groups (residents, assistants and senior surgeons) in their steadiness, instrument manipulation and execution time. When the students performed the Micro-Clock test, there was a significant improvement in movement fluidity as well as the execution time between the first and ninth test. Nevertheless, the execution time did not improve further after the fourth test. The Micro-Clock is a useful and reliable tool for teaching microsurgery skills and testing the maintenance of skills in qualified microsurgeons.
本研究使用了一种名为“微型时钟”的教育工具，该工具受Chan的“全天候”训练模式启发。微型时钟由一块手术海绵组成，上面以时钟的形状配置了12根缝合针。要求受试者尽快将一根小缝线穿过针孔。在每次试验过程中评估稳定性和器械操作，并从1到3进行评分。执行时间以秒为单位进行测量。15名教员进行了一次微型时钟测试，以验证该工具评估合格显微外科医生技能的能力。接下来，9名参加显微外科学文凭课程的学生在课程期间进行了9次测试，以衡量他们的进步情况，并评估他们的掌握程度和执行速度。三个教员亚组（住院医师、助理和资深外科医生）在稳定性、器械操作和执行时间方面没有显著差异。当学生进行微型时钟测试时，在第一次和第九次测试之间，动作流畅性以及执行时间有显著改善。然而，在第四次测试后，执行时间没有进一步改善。微型时钟是一种用于教授显微外科手术技能和测试合格显微外科医生技能保持情况的有用且可靠的工具。
