A virtual-reality simulator was developed for the training of Otolaryngology (Ear-Nose-Throat) surgical residents to perform myringotomy, a relatively common surgical procedure in which an incision is made in the eardrum mainly to treat middle-ear infections. The simulator presents the trainee with a three-dimensional (3D) virtual model of the ear that can be viewed through a mock surgical microscope consisting of a stereo visor mounted on a custom-designed stand. The trainee interacts with the virtual ear using a real myringotomy blade, the movements of which are tracked in real time using a stereo optical tracker. Interactions of the blade with virtual tissues are calculated and rendered on the visor using freely available physics and graphics software engines. Six experienced surgical residents and surgeons assessed the effectiveness of the simulator as a viable training tool by completing a questionnaire designed specifically for this study after using the simulator. Surgeons and residents were positively impressed by the simulator as a training tool and would recommend its use as part of training.
开发了一种虚拟现实模拟器，用于培训耳鼻喉科（耳-鼻-喉）外科住院医师进行鼓膜切开术，这是一种相对常见的手术，主要用于治疗中耳感染。该模拟器为学员提供了一个可以通过模拟手术显微镜查看的三维（3D）虚拟耳朵模型，该显微镜由安装在定制设计的支架上的立体眼罩组成。学员使用真实的鼓膜切开刀与虚拟耳朵进行交互，其运动使用立体光学跟踪器实时跟踪。刀片与虚拟组织的相互作用使用免费提供的物理和图形软件引擎在眼罩上进行计算和呈现。六位经验丰富的外科住院医师和外科医生在使用模拟器后，通过专门为此研究设计的问卷，评估了模拟器作为一种可行的培训工具的有效性。外科医生和住院医师对模拟器作为一种培训工具印象深刻，并会推荐将其用作培训的一部分。
