  1. Da Vinci Surgical Robot: Global Deploymentand Known Problems Andrew Priddis April 24, 2013

  2. Industrial and Course Applications

  3. Industrial Applications Minimally invasive complex surgery Urology Gynecology General Surgery Colorectal Head and Neck http://youtu.be/C17-bGquIjI

  4. Industrial Applications Gal Bladder Removal

  5. Industrial Applications Gal Bladder Removal

  6. Course Applications Robot Kinematics Differential Kinematics

  7. Robot Kinematics Remote Center Point of Insertion cannot move 7 Degrees of Freedom Each has 90º of articulation

  8. Differential Kinematics Map movement of doctors hands to movement of tools

  9. Global Application

  10. Global Reach 2585 Units Worldwide Future ability to remotely perform surgeries

  11. Limitations to Global Distribution Cost $2.5 Million for initial system $150K Maintenance per year No market competition Size System weighs½ ton Difficult to ship securely

  12. Known Issues

  13. Reports filed by FDA • 500 Reported problems since January 2012 • Woman died when robot nicked a blood vessel • Man’s Colon perforated by robot • Robotic arm hit patient in the face during procedure • Robotic arm wouldn’t release tissue. Total system shutdown was required to get robot to open the gripper. • 5 deaths • Reports of burns • Electrical Arcing • No reports of robot having control problems

  14. Possible Problems • Lack of Haptic feedback • According to Intuitive Surgical there is “some force feedback” • Mostly occurs in collision avoidance • No consideration given to robotic arms outside patient • Robot arms could collide with other objects in the room • Lack of training • Viewed as less difficult surgery • Poor electrical insulation

  15. Conclusions • Highly capable in complex surgeries • Paper Airplane • Global distribution limited by cost • Patient access also limited by cost • Excellent control of robotic arms • Doctors unable to fully comprehend environment • There are potential electrical problems
