摘要

使用带有虚拟现实的手术模拟器,外科医生可以练习不同类型的手术,以最大限度地降低患者在真实手术中的风险。本文介绍了一种具有触觉反馈的微创手术(MIS)模拟器的原型,该模拟器应用于内窥镜鼻内手术。本研究分为三个部分:四自由度(俯仰、偏航、翻滚、移动)刚性内窥镜装置的仿真,用于快速触觉渲染的鼻组织简化模型,以及与具有碰撞检测功能的虚拟现实仿真系统的集成。本文的主要贡献是刚性内窥镜模型,该模型使用简单的杠杆作为在鼻孔中旋转的力转换器。所得结果表明,该系统具有较好的交互仿真响应。

Endoscopic endonasal haptic surgery simulator prototype: A rigid endoscope model
The use of surgical simulators with virtual reality allows surgeons to practice diverse types of procedures for minimizing any risk on patients during the real surgery. This paper describes a prototype for a Minimal Invasive Surgery (MIS) simulator with haptic feedback applied to an endoscopic endonasal surgery. The research is divided in three parts: the simulation of a rigid endoscope device with four degrees of freedom (pitch, yaw, roll and dolly), a simplified model of the nasal tissue for fast haptic rendering and the integration with a virtual reality simulation system with collision detection. The main contribution of the paper is the rigid endoscope model using a simple lever acting as a force transformer pivoting in the nostril. The obtained results show a suitable response of the system for an interactive simulation.
