简要总结

Neurosurgery is a high-stakes surgical specialty where errors can result in significant morbidity. The amount of force applied simultaneously on the brain with multiple different instruments during complex neurosurgical procedures is a critical safety metric that, to the investigators' knowledge, has not been previously measured in a realistic operative environment.

The investigators have therefore developed a simulation platform integrating an ex vivo calf brain and a 3D-printed skull model attached to a force sensor capable of capturing real-time forces applied to the brain. A case series study will be conducted to evaluate the pattern of force applied. Medical students, neurosurgical residents, and staff neurosurgeons from McGill University will be recruited to perform subpial resections using our ex vivo calf brain simulation platform. The forces applied by the microscissors, bipolar forceps, and ultrasonic aspirator onto the brain will be captured. This study aims to demonstrate the spectrum of force applied during a neurosurgical procedure using an ex vivo calf brain model.

详细描述

Background and Rationale: The subpial resection technique is a complex neurosurgical procedure that is essential for brain tumor and epilepsy surgery. However, opportunities for trainees to gain hands-on experience with this procedure without risk to patient safety are limited. The force applied on the brain during tool-tissue contact is a critical factor impacting patient safety. While virtual simulation platforms enable force monitoring, ex vivo animal brains cannot readily capture quantitative data. The investigators have therefore developed a prototype of a simulation platform that integrates a force sensor and a calf brain and can accurately detect real-time forces during simulated subpial resections. This study seeks to gauge the force spectrum using this ex vivo calf brain force detection system.

Hypothesis: The simulation platform will accurately measure forces applied by novice, intermediate, and expert participants with surgical instruments on an ex vivo calf brain during simulated subpial resection procedures.

Co-Primary Outcomes: To assess the individual and combined instrumental force applications during subpial resection procedures in an ex vivo calf brain model.

Secondary Outcome: To differentiate levels of expertise of trial participants.

Setting: Montreal Neurological Institute and Hospital, McGill University, Montreal, Quebec, Canada.
