smoke evacuation
The continuous removal of surgical smoke generated during electrocautery in minimally invasive procedures.
Full Definition
A safety protocol requiring the active removal of smoke plume generated by electrocautery, laser, or ultrasonic devices during minimally invasive surgery. Smoke evacuation systems filter toxic particles and maintain clear visualization while protecting surgical personnel from potentially harmful vapors. Modern systems integrate with laparoscopic insufflators to maintain pneumoperitoneum pressure while removing smoke.
Usage
Usage note: Essential for occupational safety documentation in surgical reports.
