The Ionwand™ creates negatively charged gas ions in the abdominal cavity, which move towards the “positive” patient tissue. As the ions move, they collide with water vapour and particulate matter and draw them away from the surgical site. Particles land, and the electrical charge flows back to the generator.
Electrostatic precipitation accelerates the natural process of sedimentation. It is faster and more efficient than smoke evacuation, with no loss of pneumoperitoneum.
Ultravision™ vs filter-based smoke evacuator
When switched on before cutting, Ultravision™ minimises surgical smoke production and precipitates 99% of particles within 30 seconds*
After 1 minute of continuous use, smoke evacuation removes 30.2% of particles (by number).
In the same time period Ultravision™ precipitated 99.9% of particles, independent of particle size, from 7nm to 10µm (p<0.05)*.
