Wasp egg-laying organ inspires new tool to reduce trauma in minimally invasive surgery

A new surgery tool based on the egg-laying organ of parasitic wasps could advance minimally invasive surgery by enabling tissue removal in deeper areas of the body while further minimising trauma and patient recovery time. Researchers at Delft University of Technology in the Netherlands based their prototype on the ovipositor of wasps, an ultra-thin flexible organ, which uses friction forces generated by sliding internal blades to achieve efficient transport on a small scale.
