Scientists have talked about a “remarkable” discovery about the wasp-like insect plant-cut mechanisms, suggesting that it can revolutionize modern surgical techniques.
Researchers at the University of Herriot-Watt carefully studied how female arifles receive such accurate incisions when accumulating their eggs within the tissue of the plant.
Their findings suggest that the egg -laying organs of the sofly, known as an oviposter, acts as a biological mutual saw, spontaneously makes sense to understand when to cut and when to displace the material.
Severe, the female saws should preserve the plant while laying eggs. A colleague-reviewed study confirmed their natural selectivity in cutting, causing structural damage to the host plant.
Dr. Varduguer Mallorkvi said: “We have made some remarkable discovery – a cutting mechanism that essentially thinks for ourselves.
“The egg -laying organ of the softest can cut through the tissues of the soft plant, but automatically avoids the hard internal” plumbing “of the plant which includes tubes carrying water and nutrients.
“This ensures that the plant survives and serves as a food supply for the larvae coming from the eggs.
“This selective cutting occurs perfectly through teeth geometry and composition that interact with various physical properties of the plant – not a sensor or computer but is refined by the development of millions of years of elegant engineering.”
The research team extended the sofly’s cutting mechanism 400 times and tested it on the material that mimics human tissue.
They found the system operating on an uniform “ultimate stress range” displacing the bottom parts of this limit.
Professor Mark Desmuliz states: “This discovery has potential potential implications for surgical practice in this discovery.
“Current surgical equipment often struggle in complex operations. Surgeons often work in a blood-flowing environment where visibility is poor and accidentally has a higher risk of cutting significant structures.
“A surgical device based on this natural mechanism can spontaneously avoid important tissues, while it is required, essentially giving surgeons a tool that helps prevent mistakes.
“The surgeons now require further input, but there is a possibility of possibilities in this newly discovered mechanism.”
The team used advanced electron microscopy and 3D imaging, so that the exact geometry of saws of saws could be decoded.
They discovered that small serials work in concerts with large protrusions to create selective cutting action.
This is the passive nature of this mechanism that can make it useful for surgery, they argue, as surgeons often work in a blood-flowing environment where visibility is poor.
The findings from the work of the international team were published in Journal Bioinspiration and Biometics.
