In order to provide realistic haptic feedback, simulators must incorpo- rate accurate computational models of the in-vivo mechanical behavior of soft tissues. Surgical simulation technology has progressed rapidly but lacks a com- prehensive database of soft tissue mechanical properties with which to incorpo- rate. Simulators are often designed purely based on what "feels about right;" quantitative empirical data are lacking. It is important to test tissues in-vivo and apply surgically relevant ranges of force, deformation, and duration. A motor- ized endoscopic grasper was used to test seven porcine abdominal organs in- vivo, in-situ, and ex-corpus with cyclic and static compressive loadings. Elastic and stress relaxation characteristics were examined. Results from liver are pre- sented here. Notable differences were found between successive squeezes and between conditions for elastic and relaxation behaviors. |
