VERY Remote Robotic Surgery

Filed under: Surgery

remote bedside manner, tooNothing worse than coming down with appendicitis on the moon. Luckily, when the next manned moon missions take place (and that will be when...?), the crew of hardened former military pilots won't have to bring along some wuss MD. Instead, they'll have a robotic surgery system onboard:

Using a cramped undersea laboratory off Florida's Atlantic coast, NASA astronauts and medical experts have teamed with an experimental robot to demonstrate long-distance surgical procedures that might one day save the life of a critically injured explorer on the moon or Mars.

...During their stay aboard the 43-foot-long Aquarius, submerged among the coral reefs off Key Largo, Fla., physician Tim Broderick and three astronauts - Dave Williams, Ron Garan and Nicole Stott - assisted as Canadian surgical researchers 1,250 miles away sent commands to a robot inside the laboratory.

Responding to those commands, the portable robot sutured a badly damaged vein in the wounded arm of a patient simulator, a lifelike medical teaching aide constructed of rubber and fabrics that mimic human tissue and contain bloodlike fluid.

During the experiment, researchers delayed the robot's response to Anvari's [Dr. Mehran Anvari, a Canadian pioneer in tele-robotic-assisted surgery -ed.] commands by two seconds. The lag matched the time it would take communications from Earth to reach an astronaut undergoing medical treatment on the moon.

"It was tough. Your brain has to learn that with a two-second delay, you are trying to predict where the (robot's) arm will end up being seconds later," Anvari said.

The Mars lag time would be a more challenging 12 minutes.


From a technophilic perspective, this is wicked cool. However, from an engineering perspective, it seems like for the same cost in time, money and complexity, you could train one flight crew in basic surgical procedures. Of course this is coming from the only non-medical Medgadgeteer on staff.

The problem, of course, is that it is non-basic surgical skills which may be needed. This NEEMO project is a great step forward to being able to carry out surgery in isolated environments!

I suppose in efforts to be prepared for anything, being able to perform needed non-trivial surgery makes the list. The knowledge gained as part of this project could easily be useful in other applications.

Besides, anything that advances the state of robotic technology can be funded by my tax dollars any day.

I applaud the efforts of the NEEMO team and believe this is exciting technology. However, I do think that commentary about about a "wuss MD" is a little unnecessary and considerably too low-brow for your general level of sophistication.

Brant - the "wuss" comment was mean to be "in-character," comparing the usually elite physical condition of an astronaut with the stereotypically more docile doctor...and certainly not meant to be offensive.

Of course, it's been my experience that many surgeons (the ones being replaced by the robotic system here) are in fact quite tough themselves. Hours of standing in awkward positions while wrestling around the patient's innards takes some pretty good conditioning.

Anything that advances the scope of medical work is good investment in my opinion. With the rising cost of doctor's bills and medical insurance I believe that this would be cause for the medical field to seriously look at continueing to raise the cost of healthcare. While I have nothing to be repaired as of current, by a robot such as this; I would be willing to allow such a machine to be tested on myself. I'm also sure that there are a large number of other individuals who would do the same.

The problem with technology like this is it scares the general public. While a person can be smart, People as a whole are dumb and panic easily. I can almost guarantee that there will be some back woods individual say something ignorant along the lines of "Oh My GOD! the robots are taking over the world!" Sorry but the ignorant masses irratate me, because its the ignorant masses that hold technology back, And it is my firm belief that Technology like this should be improved so that it is avaible for use. an example of where a robot doctor would have been handy: 2/12/2005 a young man went through a window and severed his tendon artery and nerve in his hand. He waited 8 hours before a surgeon could do the surgery because the surgeon was busy seeing patients. If we had this technology already and implimented the surgery could have been done immediately.

As a Geek I embrace Technology like this, but, I'm sad to say I doubt it will be embraced on anytype of large scale anytime soon even after its perfected, due to the large number of the ignorant masses who think technology peaked at frozen pizza and bottled beer.
