【摘要】：目的基于腹腔镜模拟手术训练缺乏有效的训练系统的问题,本文采用双目视觉系统设计了一种腹腔镜模拟手术三维纠偏系统,以达到将原设定切割路径呈现在程序界面,同时实时显示手术刀尖端切割路径,并实现纠正切割路径。方法在Visual Studio 2010软件平台上对Micron Tracker进行二次开发,调用Micron Tracker函数库进行Marker点的识别,采用拉格朗日拟合算法拟合出原定路径,通过逐一调用器械尖端坐标画出器械尖端走过的轨迹。结果使用纠偏系统的A组志愿者和不使用纠偏系统的B组志愿者之间的偏移量比较得出:A组的25次实验整体X轴和Y轴正负平均偏移量均小于B组的偏移量;A、B两组第1次和第5次实验相比,正负平均偏移量均显著减少(P0.05),且随着受试者操作次数的增加偏移量呈减小的趋势;对A、B两组的正负偏移量进行方差分析,可得因素(纠偏系统)对实验指标(偏移量)有显著影响(FF-crit)。结论本研究设计的纠偏系统能有效减少培训者在培训过程中的偏移量及培训时间,提高培训效率。
[Abstract]:Objective based on the lack of effective training system for laparoscopic simulated surgery, this paper designs a three-dimensional correction system for laparoscopic simulated surgery by using binocular vision system, so that the original set cutting path can be presented in the program interface.At the same time, the cutting path of scalpel tip is displayed in real time, and the cutting path is corrected.Methods the second development of Micron Tracker was carried out on the Visual Studio 2010 software platform, and the Marker points were identified by calling the Micron Tracker function library, and the original path was fitted by Lagrange fitting algorithm.The trace of the tip of the instrument is drawn by calling the coordinate of the tip of the instrument one by one.Results the deviation between group A volunteers using rectifying system and group B volunteers without correction system was compared. It was concluded that the average offset of positive and negative X-axis and Y-axis in 25 experiments in group A was smaller than that in group B.Group 1 and experiment 5,The average positive and negative offsets decreased significantly, and tended to decrease with the increase of the number of operations. The ANOVA was used to analyze the positive and negative offsets of the two groups, and the positive and negative deviations of the two groups were analyzed by ANOVA, and the positive and negative deviations of the two groups were analyzed.The available factors (bias correction system) have a significant effect on the experimental index (deviation).Conclusion the designed bias correction system can effectively reduce the deviation and training time and improve the training efficiency.
