Virtual Reality Tumor Resection: The Force Pyramid Approach.

摘要: BACKGROUND The force pyramid is a novel visual representation allowing spatial delineation of instrument application during surgical procedures. In this study, the concept employed to create and quantify dominant hand, nondominant bimanual pyramids resection virtual reality brain tumors. OBJECTIVE To address 4 questions: Do ergonomics handedness influence structure? What are differences between pyramids? distribution forces applied in specific tumor quadrants? differentiates "expert" "novice" groups regarding their METHODS Using simulated aspirator hand sucker 6 neurosurgeons 14 residents resected 8 different tumors using CAE NeuroVR neurosurgical simulation platform (CAE Healthcare, Montreal, Quebec National Research Council Canada, Boucherville, Quebec). Position data were used quadrant distribution. RESULTS Force quantification demonstrates critical role that play on psychomotor performance resections. Neurosurgeons concentrate defined crescent lower right quadrant. Nondominant showed central peak all groups. Bimanual outlined combined impact each hand. Distinct patterns seen when stiffness, border complexity, color altered. CONCLUSION allow regions requiring greater ability resect. This information can focus improve resident technical skills training.
