Abstract: Introduction:One of the main drawbacks in surgical system for laser phonomicrosurgery is the mechanical joystick for laser controll.This type of interface and no possibility to personalize the programming capabilities is the major limiting factor for improved surgical precision,quality and safety,requiring extensive surgeon practice. Material and methods:A new robotic system was designed to overcome these drawbacks with a more ergonomic,intuitive and programmable surgical laser control device:a touch interface with dynamic intraoperative planning capabilities.The system is based on a large-range laser scanner fully controlled by a stylus on a tactile sensor.It gets to aim the laser in real-time over the whole surgical field and allows path memorization letting accurate repetitions of surgeon-defined laser paths.This enables pre-execution surgical action tracking and unmatched control for long cuts.Paths of any shape and length are dynamically planned too with the plain stylus device. Results:Preliminary trials on ex-vivo swine larynxes and artificial targets have assessed the new system as highly intuitive,effective and safe:Drop of80% in max absolute error and about50% in RMS error were shown with the stylus interface in path-follow trials.Dynamic planning has demonstrated its benefits: no error was observed in trials, getting only .03mm mean RMS error under a40x microscope magnification.The research leading to these results has received funds from the µRALP European project.
