Optical fiber sensor array for artery/lump detection

In this study, a new optical fiber tactile sensor array is introduced for use in minimally invasive surgery systems. The proposed sensor helps surgeons to locate hidden harder tissues such as lumps and arteries within soft background tissues. Unlike currently available electrically-based tactile sensors, the proposed sensor is insensitive to electromagnetic fields and is electrically passive. It also performs under both dynamic and static loading conditions. The sensor was experimentally tested to locate a phantom solid artery/lump surrounded by an artificial soft background tissue.
