Limitations to Global Distribution

Cost$2.5 Million for initial system$150K Maintenance per yearNo market competitionSizeSystem weighs tonDifficult to ship securely

Known IssuesReports filed by FDA500 Reported problems since January 2012Woman died when robot nicked a blood vesselMans Colon perforated by robotRobotic arm hit patient in the face during procedureRobotic arm wouldnt release tissue. Total system shutdown was required to get robot to open the gripper.5 deathsReports of burnsElectrical ArcingNo reports of robot having control problemsPossible ProblemsLack of Haptic feedbackAccording to Intuitive Surgical there is some force feedbackMostly occurs in collision avoidanceNo consideration given to robotic arms outside patientRobot arms could collide with other objects in the roomLack of trainingViewed as less difficult surgeryPoor electrical insulationConclusionsHighly capable in complex surgeriesPaper AirplaneGlobal distribution limited by costPatient access also limited by costExcellent control of robotic armsDoctors unable to fully comprehend environmentThere are potential electrical problems
