3mm aka scarless surgery. Yes huge opportunity. robotics make the 3mm possible hence there wouldn't be any bulkiness I can think of. Smaller incisions means less scarring potentially and even less invasive. The robot will allow for this. What is SPORTS incision diameter now? HAHAHAH 8 minute abs
Some surgeons wont like single site bc they feel it could be a hernia maker, but there is still a market for it.
