Abstract
This paper presents a novel miniaturized
force-indentation depth (FID) sensor designed to conduct
indentation on soft tissue during minimally invasive surgery. It
can intra-operatively aid the surgeon to rapidly identify the
tissue abnormalities within the tissue. The FID sensor can
measure the indentation depth of a semi-spherical indenter and
the tissue reaction force simultaneously. It make use of with
fiber optical fiber sensing method measure indentation depth
and force and is small enough to fit through a standard trocar
port with a diameter of 11 mm.
The created FID sensor was calibrated and tested on silicone
block simulating soft tissue. The results show that the sensor can
measure the indentation depth accurately and also the orientation of the sensor with respect to the tissue surface whilst
performing indentation.
