Tissue Discrimination via Electrical Impedance Spectroscopy for Neurosurgical Robots

Abstract

The BRIDGE project "Towards intelligent sensor-enhanced robotic neurosurgery" proposes a robotic screw placement technology and a surgical approach. It is based on local sensing and mapping techniques of the mechanical and electrical tissue properties, assessed continuously and in real-time while drilling the pedicle screw hole. The technology is developed for spine fusion surgeries, yet the fundamentals of the approach can be applied in other surgical operations involving drilling.
