Abstract

A surgical simulator with real-time tactile perception is produced to replicate cochlear implantation. Visual and force feedback are provided during electrode insertion into a virtual 3D model of the human Scala Tympani (ST). The haptic representation is based on real-world, physical data. Force profiles are compared with experimental insertion studies for system validation. This system is the first of its kind to offer haptic modelling and force quantification during real-time insertion of a virtual Cochlear Implant (CI). The methods presented may be applied to other medical procedures where visual feedback is precluded, to enhance tactile perception and medical instruction.
