Final Report Summary - STING (STING - A Soft Tissue Intervention and Neurosurgical Probe)

Needle steering is complex and remains challenging, due to the difficulty of controlling the needle tip within soft tissue and the paramount need to keep the patient safe at all times. The ERC STING project aimed to tackle the outstanding open research challenges that stood in the way of the clinical application of a novel needle steering design, which is based on the egg laying channel of certain wood boring wasps. By coupling interlocked needle segments with a reciprocal insertion strategy, where each segment is pushed forward of the others in turn, it was possible to demonstrate full three-dimensional needle steering with reduced tissue deformation and strain around the needle-tissue interface. It was also possible to assess the performance of an integrated system, comprising a clinically sized, 2.5 mm outer diameter needle, novel control hardware and software, and a real-time imaging and navigation front end, within a laboratory setting, on both synthetic phantoms and ex vivo tissue. In doing so, the project contributed to the current state of the art in different fields, including needle steering (both hardware and software), tool-tissue interaction modelling and measurement, and real-time trajectory following.
