Adapting to Technology in Minimally Invasive
Surgery

Laparoscopic Surgery

• Laparoscopic surgery refers to minimally
  invasive surgery in the abdomen.
• Decreases bleeding during surgery
• Decreases healing time afterwards

Laparoscopic Surgery

• Inflate stomach with CO2
• Insert camera, scissors, scalpel
• Friction forces decrease surgeon efficiency and
  safety
• Lack of depth perception can turn minimally
  invasive surgery into open surgery

Our Research The Goal

• Create a haptic interface that provides simulated
  resistance measurements of various tissues
• Libraries
• OpenGL
• OpenHaptics
• Haptic device
• Sensables Phantom Omni

New Project

• Create a haptic simulation approximating the
  spring constant of a blown up balloon
• Easy interpolation of real-world object
• Shortcut to complex simulated organ

Future Work

• Mass-spring network possibilities
• Download rendered organs and add haptic
  properties
• Analyze user trials for precise measuremens
