The daVinci robot, as cutting edge as it is, is still very much "version 1.0" of a new technology. The two complaints that surgeons most make about the robot is that it lacks any force feedback (imagine performing surgery with two numb hands) and that the robot arms are not able to bend.
As in the case of PCs, future surgical robots will improve upon version 1.0.
Canadian startup Titan Medical (TITXF) is developing a single-site surgical robot called Amadeus that addresses both of these issues. They were issued a patent last year for a robotic hand controller than provides haptic feedback (ie the surgeon can feel in their hand the end of the robot touching tissue), and their robot arm is bendable and provides 7 degrees of freedom.
Titan issued a press release yesterday that suggests that they're making great strides toward commercializing Amadeus:
Of course not. On the other hand, if Titan perfects their robot and then gets gobbled up by JNJ or Covidien, then Intuitive might have a worthy opponent. Interestingly enough, Titan's new CEO is an Ethicon (JNJ) ex sales veep, and they hinted in their press release that they're working with an outside medical device company to complete work on Amadeus.
