Abstract: This paper introduces a kind of nasoscope surgery simulation system used in rhinologist simulation training, and discusses the actualization of related techniques such as system structure design, 3D reconstruction, collision detection, elastic deformations of soft tissues and force feedback. It also briefly introduces its multiplicate navigation modes, virtual instruments and four kinds of simulation surgery.

Key words: Virtual reality, Surgery simulation, Nasoscope surgery, Force feedback
