Endoscopy has recently been introduced to endonasal transsphenoidal pituitary surgery as a minimally invasive procedure for the removal of various kinds of pituitary tumors. To reduce morbidity and mortality with this new technique, the surgeon must be well-trained and well-prepared. Virtual endoscopy can be beneficial as a tool for training, preoperative planning, and intraoperative support. This paper introduces STEPS, a virtual endoscopy system designed to aid surgeons in getting acquainted with the endoscopic view of the anatomy, the handling of instruments, the transsphenoidal approach, and challenges associated with the procedure. STEPS also assists experienced surgeons in planning a real endoscopic intervention by getting familiar with the individual patient anatomy, identifying landmarks, planning the approach, and deciding upon the ideal target position of the actual surgical activity. The application provides interactive visualization, navigation, and perception aids and the possibility of simulating the procedure, including haptic feedback and simulation of surgical instruments.
内镜检查最近已被引入鼻内镜经蝶窦垂体手术，作为一种用于切除各种垂体肿瘤的微创手术。为了通过这种新技术降低发病率和死亡率，外科医生必须接受良好的培训并做好充分准备。虚拟内镜作为一种培训、术前规划和术中支持工具可能会有所帮助。本文介绍了STEPS，这是一种虚拟内镜系统，旨在帮助外科医生熟悉解剖结构的内镜视图、器械操作、经蝶窦入路以及与该手术相关的挑战。STEPS还通过让经验丰富的外科医生熟悉个体患者的解剖结构、识别标志、规划入路以及确定实际手术活动的理想目标位置，协助他们规划实际的内镜干预。该应用程序提供交互式可视化、导航和感知辅助工具，以及模拟手术过程的可能性，包括触觉反馈和手术器械模拟。
