Nowadays, modern technology requires procedures to be very precise, for example when using needles or inserting catheters, and leave minimal scars on the patient's body. Nature has many features that could be useful in the world of medicine. An example is how a wasp is able to lay her eggs out of a 0.2-0.3mm diameter tube. It can even lay its eggs into wood at a depth of 20mm. A wasp lays its eggs into wood without any rotational movement, this is due to the laying tube having a drilling mechanism by being both flexible and stable. This is a feature that is specifically needed in brain surgery. By having a flexible needle, surgeons are able to get to the deepest parts of the brain, in order to analyze and diagnose it, without having to rotate the needle or risk causing damage to it using the other invasive devices.
