在虚拟环境中,虚拟机被广泛使用,并提供了一个衡量性能的标尺。目前定义医学模拟指标的方法仍然是一门艺术,而不是一门科学。在此,我们报告了一种实用的科学方法来定义指标,特别是针对计算机辅助腹腔镜技能培训。我们还提出了一个标准化的全球评分系统,可用于不同的腹腔镜培训师和任务。这些指标是根据腹腔镜外科医生应该掌握的相关技能以明确的方式定义的。我们使用了一个五自由度的设备和一个软件平台,能够1)跟踪两个腹腔镜仪器的运动2)真实的时间信息处理和反馈提供。进行了验证研究。结果表明,我们的指标和评分系统代表了一种技术上合理的方法,可以很容易地纳入计算机化的教练的任何任务,使标准化的性能评估方法。
Metrics are widely employed in virtual environments and provide a yardstick for performance measurement. The current method of defining metrics for medical simulation remains more an art than a science. Herein, we report a practical scientific approach to defining metrics, specifically aimed at computer-assisted laparoscopic skills training. We also propose a standardized global scoring system usable across different laparoscopic trainers and tasks. The metrics were defined in an explicit way based on the relevant skills that a laparoscopic surgeon should master. We used a five degree of freedom device and a software platform capable of 1) tracking the motion of two laparoscopic instruments 2) real time information processing and feedback provision. A validation study was performed. The results show that our metrics and scoring system represent a technically sound approach that can be easily incorporated in a computerized trainer for any task, enabling a standardized performance assessment method.
