The level of realism in virtual reality trainers might not be proportional to its didactic value. As an example, three exercises to train suturing skills are proposed in this article. They use a discrete thread model with a simple but good enough behaviour, and constitute a training means for three laparoscopic skills: (1) Accurate grasping, which trains grasping a precise point in the thread. (2) Coordinated Pulling, which trains tightening the thread co-ordinately and in different space orientations; and (3) Knotting, which allow the surgeon to practice this manoeuvre. These three exercises, found interesting among experts in surgical training, are now being validated in MIS workshops at the Minimally Invasive Surgery Centre of Cáceres (Spain).
虚拟现实训练器中的逼真程度可能与其教学价值不成正比。例如，本文提出了三种用于训练缝合技能的练习。它们使用具有简单但足够良好行为的离散线模型，并构成了三种腹腔镜技能的训练手段：（1）精确抓握，训练抓握线中的精确点；（2）协调牵拉，训练在不同空间方向上协调收紧线；以及（3）打结，让外科医生练习这一操作。这三种练习在外科训练专家中被认为很有趣，目前正在西班牙卡塞雷斯微创外科中心的微创外科研讨会上进行验证。
