Motivation
• Minimal Invasive Surgery is currently in vogue
• Operations once performed “open” are now done almost
exclusively using laparoscopes
• The latest trend is to perform robots assisted surgery
• All these new skills require special training
– Hand Eye Coordination
– Navigation of Camera and Laparoscopic instruments in a confined
space

9
Challenges
• The first challenge is to model the human anatomy
– Making 3D models that exactly look like the original ones
• The second challenge is to simulate this 3D model to act like the
real thing
– For example a 3D model of heart can only be called a heart model if it
acts like a human heart too, beating and pumping blood
– Simulating Tissue behavior
• The third challenge is to simulate the environment within the
human body
– What happens if an external object pokes a tissue?
– In real-life the tissue or that part of the body would start to bleed
internally
– How can that be simulated

Our Approach
• We are utilizing open source framework for
developing our system
• Using SOFA (Simulation Open Framework
Architecture) as the core of our system
• Creating simulations of real scenarios from Holy
Family’s database of over 100 videos
• Formal Verification of the system

– A minor glitch in the analysis phase could result in disastrous
consequences
• Potential Analysis Aspects
– Evaluating Behavioral Correctness of Telesurgical Robotic
Systems
– Formal Reliability Analysis of Telesurgical Robotic Systems
