New tool for cancer ops

A new surgical tool inspired by wasps could transform cancer ops.

Currently, the removal of tissue such as tumours is done using suction, but these tools are prone to clogging and there are parts of the body they can’t reach.

However, researchers at Delft University have developed an instrument which is inspired by parasite wasps and uses friction rather than suction to remove tissue.

The tool has six blades which move in turn and can reach small spaces which traditional methods cannot. Scientists have a working prototype and hope the tool will be ready for use by surgeons in a matter of years.
