A System for Characterizing Intraoperative Force Distribution during Operative Laryngoscopy
Investigators are increasingly finding that “smart” surgical instrumentation may improve clinical outcomes as greater tool-tissue contact forces are correlated with peri- and post-operative complications. While previous efforts to study intraoperative pressure distributions in otolaryngology have been limited by static equilibrium assumptions and cadaver-only testing, we present an integrated data acquisition system for detecting intraoperative forces and pressures during operative laryngoscopy using sixteen piezoresistive sensors. This low-cost and custom system can be calibrated within one hour prior to procedure with 1–2.5% error, and cadaver and live patient trials have shown comparable force and pressure data to literature values...
