Investigation of Distance to Break Using Compliant Nonlinear and Linear Materials in a Simulated Minimally Invasive Surgery Task
Year: 2015
Type: dissertation
Abstract: Accurate interpretation of the mediated haptic information in minimally invasive surgery (MIS) is critical for applying appropriate force magnitudes into soft tissue with the aim of minimizing tissue trauma. Force perception in MIS is a dynamic process with surgeon's administration of force into tissue revealing information about the remote surgical site which will further inform the surgeon for additional haptic interaction. The relationship between applied force and material deformation rate has been shown to provide biomechanical information specifying the distance remaining until the tissue would fail, which has been termed distance-to-break (DTB). The current study continues the investigation of whether observers can use DTB to stop before a tissue's failure point. Similar to past results, observers could reliably perceive DTB in simulated nonlinear biological tissues.
