腹腔镜手术技能训练的最佳方法是有争议的。一些人主张在手术室观察，而另一些人则提倡动物和模拟模型或相关的与手术相关的任务组合。所有这些方法共有的熟练评估方式是熟练的外科医生主观评估。为了定义评估性能的客观手段，开发了一种仪器腹腔镜抓毛，测量了外科医生手/工具接口处的力/扭矩。测得的数据库表明经验丰富和新手外科医生组之间存在实质性差异。分析力和扭矩与手术过程中的状态过渡相结合，可以客观地测量MIS的技能。教新手外科医生在手术过程中限制过多的负荷并提高运动效率，可能会导致软组织的损伤减少，而在腹腔镜手术期间浪费的时间较小。此外，本研究中测得的力/扭矩数据库可用于开发现实的虚拟现实模拟器和医疗机器人性能的优化。
The best method of training for laparoscopic surgical skills is controversial. Some advocate observation in the operating room, while others promote animal and simulated models or a combination of surgical related tasks. The mode of proficiency evaluation common to all of these methods has been subjective evaluation by a skilled surgeon. In order to define an objective means of evaluating performance, an instrumented laparoscopic grasper was developed measuring the force/torque at the surgeon hand/tool interface. The measured database demonstrated substantial differences between experienced and novice surgeon groups. Analyzing forces and torques combined with the state transition during surgical procedures allows an objective measurement of skill in MIS. Teaching the novice surgeon to limit excessive loads and improve movement efficiency during surgical procedures can potentially result in less injury to soft tissues and less wasted time during laparoscopic surgery. Moreover the force/torque database measured in this study may be used for developing realistic virtual reality simulators and optimization of medical robots performance.
