腹腔镜手术的虚拟仿真在培养外科新手和实习医师方面越来越受到重视。虚拟手术仿真具有许多优点，因为它可以为用户提供一个安全的环境，没有动物或病人的科目。虽然市场上有几种解决方案，但没有报告的研究对腹腔镜胆囊切除术（胆囊切除手术）的虚拟模拟进行了详细的技术描述，这是使用腹腔镜外科手术进行的主要手术之一。在这里，我们提出了一个现实的腹腔镜胆囊切除术培训模拟器。该系统是通过应用最先进的计算机图形技术，使用一个开放源代码库，并提出了一种新的变形网格雕刻方法。变形网格划分是一种基于体的方法，它利用了势场和六面体有限元法。在本文中，我们描述了用于实现腹腔镜胆囊切除术模拟的详细技术。实验和用户研究结果表明，该系统具有较高的真实感和逼真度，能够真实的实时模拟胆囊切除手术。
Virtual simulation of laparoscopic surgery is getting attention for training novice surgeons and medical residents for practice. Virtual surgical simulation has many advantages because it can provide users with a safe environment without animal or patient subjects. Although several solutions are available in the market, there are no reported studies with detailed technical descriptions of the virtual simulation of laparoscopic cholecystectomy (gallbladder removal surgery), one of the major surgeries performed using laparoscopic surgical procedures. Here, we present a realistic laparoscopic cholecystectomy training simulator. The system was developed by applying state-of-the-art computer graphical technologies using an open source library and proposing a new method of deformable mesh carving. The deformable mesh carving is a volume-based method using potential fields and hexahedral finite element method. In this paper, we describe the detailed techniques used to realize the laparoscopic cholecystectomy simulation. The experimental and user study results prove that the presented system simulates the cholecystectomy procedures in real time with high degree of realism and fidelity.
