Really? So you're telling me that the surgeons who have been doing lap colons and lap bariatrics without a robot for all of these years are going to suddenly transition to the robot because of a stapler? Doubtful. What clinical benefit are you going to preach to a surgeon that already has good outcomes? Let's be honest, a good lap general surgeon isn't going to transition to the robot because of a stapler. They are already doing those cases in less time and with the exact same, if not better outcomes, than the robot.
Also, keep in mind that the bulk of the business for Ethicon and Covidien are open stapling devices and those cases aren't going away.
From what I have seen in my hospitals that have a robot, it is still GYN and URO. The general and bariatric surgeons haven't touched the old or SI robot because they've been doing those cases for years without the need for a robot. A stapler on a robot arm isn't doing to suddenly convince them to switch because there isn't a clinical benefit to switch. There is one thoracic surgeon who uses the robot but he opens 95% of the time anyways so he will still continue to use a non-robot stapler when he opens.
