In this paper, the development of an assisting system for laparoscopic surgical training is presented. With this system, we expect to facilitate the training process at the first stages of training in laparoscopic surgery and to contribute to an objective evaluation of surgical skills. To achieve this, we propose the insertion of multimedia contents and outlines of work adapted to the level of experience of trainees and the detection of the movements of the laparoscopic instrument into the monitored image. A module to track the instrument is implemented focusing on the tip of the laparoscopic tool. This tracking method does not need the presence of artificial marks or special colours to distinguish the instruments. Similarly, the system has another method based on visual tracking to localize support multimedia content in a stable position of the field of vision. Therefore, this position of the support content is adapted to the movements of the camera or the working area. Experimental results are presented to show the feasibility of the proposed system for assisting in laparoscopic surgical training.
本文介绍了一种腹腔镜手术训练辅助系统的开发。借助该系统，我们期望在腹腔镜手术训练的初始阶段促进训练过程，并有助于对外科手术技能进行客观评估。为实现这一目标，我们建议插入适合学员经验水平的多媒体内容和工作概述，并在监测图像中检测腹腔镜器械的运动。实现了一个专注于腹腔镜工具尖端的器械跟踪模块。这种跟踪方法不需要人工标记或特殊颜色来区分器械。同样，该系统还有另一种基于视觉跟踪的方法，用于将支持多媒体内容定位在视野的稳定位置。因此，支持内容的这个位置会根据摄像头或工作区域的移动进行调整。给出了实验结果，以证明所提出的系统辅助腹腔镜手术训练的可行性。
