Using tactile MIS sensing instruments under robotic control reduces the maximum force applied to the tissue by over 35% compared to a human controlling the same instrument. Accuracy in detecting the tumours was also far greater with the robot - between 59 and 90% depending on the robot control method used for palpation.

If developed further, the authors suggest that this type of instrument would particularly benefit surgeons performing lung tumour resection, where tissue often shifts significantly.
