【摘要】：内窥镜手术的发展为外科手术带来了革命性的改变,由于内窥镜手术微创的特性,使得越来越多的患者选择内窥镜手术作为主要的治疗手段。随着内窥镜手术社会需求的增大,对熟练操作内窥镜手术医生的需求也与日俱增。然而由于内窥镜手术的特性,培养和训练合格的医生往往存在很大的困难。本文针对膝关节镜手术,基于虚拟现实技术和虚拟显示软件,采用传感器和数据采集卡的方法,建立一套逼真和稳定运行的交互装置系统,模拟膝关节镜手术的操作过程。论文主要从以下几个方面进行分析和研究： (1)对膝关节镜手术的自由度进行深入分析,设计和构建一套用于模拟膝关节镜手术的硬件交互装置。在此基础上进行进一步的需求分析和结构改进,最终开发出一套符合模块化设计思想,并且可以通用于所有内窥镜手术的硬件交互装置。 (2)针对数据采集系统进行功能模块分析,结合数据采集速率和精度的要求,确定传感器和数据采集卡的选型,实现数据采集系统硬件模块设计。在硬件模块的基础上,深入分析数据采集卡的软件功能,确定多通道数据采集的软件功能模块。 (3)对交互控制进行理论分析,建立数学模型。在模块分析的基础上进行结合于虚拟膝关节镜手术的数据采集系统开发,通过一系列的关键技术研发,最终实现多通道数据采集系统。 (4)利用虚拟现实软件,结合编程开发工具,设计出一套虚拟膝关节镜手术系统。此系统用于模拟内窥镜手术操作中,关节腔内的各种组织结构的情况。此系统具有交互式特性,可以引导使用者进行各种操作,并且可以在系统中进行知识的浏览和学习。
[Abstract]:The development of endoscopic surgery has brought revolutionary changes to surgery. Because of its minimally invasive characteristics, more and more patients choose endoscopic surgery as the main treatment. With the increasing social demand for endoscopic surgery, the demand for skilled endoscopic surgery doctors is also increasing. However, due to the characteristics of endoscopic surgery, it is difficult to train and train qualified doctors. In this paper, based on virtual reality technology and virtual display software, a set of lifelike and stable operation interactive device system is established based on virtual reality technology and virtual display software, which simulates the operation process of knee arthroscopic surgery. The thesis mainly carries on the analysis and the research from the following several aspects: Firstly, the degree of freedom of knee arthroscopic surgery is analyzed in depth, and a hardware interactive device is designed and constructed for simulating arthroscopic surgery. On this basis, further requirements analysis and structural improvement are carried out, and a set of hardware interactive devices which accord with the modular design idea and can be used in all endoscope operations is developed. In view of the function module analysis of data acquisition system, combining the requirement of data acquisition rate and precision, the selection of sensor and data acquisition card is determined, and the hardware module design of data acquisition system is realized. On the basis of hardware module, the software function of data acquisition card is deeply analyzed, and the software function module of multi-channel data acquisition is determined. 3) theoretical analysis of interactive control and establishment of mathematical model. On the basis of module analysis, a data acquisition system combined with virtual knee arthroscopy is developed, and a multi-channel data acquisition system is realized through a series of key technologies. A virtual knee arthroscopic surgery system is designed by using virtual reality software and programming tools. The system is used to simulate various tissue structures in articular cavity during endoscopic surgery. The system is interactive, can guide users to operate, and can browse and learn knowledge in the system.
