Da Vinci Surgical Robot: Global Deployment and Known Problems Andrew Priddis April 24, 2013

Industrial and Course Applications

Industrial Applications Minimally invasive complex surgery Urology Gynecology General Surgery Colorectal Head and Neck

Industrial Applications Gal Bladder Removal

Industrial Applications Gal Bladder Removal

Course Applications Robot Kinematics Differential Kinematics

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

Differential Kinematics Map movement of doctors hands to movement of tools

Global Application

Global Reach 2585 Units Worldwide Future ability to remotely perform surgeries

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

Known Issues

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

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

Conclusions Highly capable in complex surgeries o Paper Airplane 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
