A Surgical Robotics Pioneer on the Future of Medical Technology

At FutureMed, Richard Satava argued for an electronic medical record that includes full body scans packed with data for every patient.


At FutureMed, Dr. Richard Satava gave an impressive presentation that
touched on everything from breakthroughs in surgical robotics to plasma medicine.
He is a professor of surgery at the University of Washington Medical
Center, but he also helped pioneer the surgical robotic system that
eventually became Intuitive Surgical’s da Vinci.


Early in his talk, Satava stressed the need for a new scientific
methodology. While the scientific method has served us well and will do
so going forward, it has limitations. In the future, we should expand
our reliance on simulation technology, which “takes our current
information technologies out of the present and brings them into the
future.” Simulation technology, once it is able to mimic human
biological processes, would disrupt the clinical trial process. “Right
now, it costs $200 million dollars and 20 years to go through a
complete, randomized clinical study,” he said. But in the future, clinical trials
won’t be based on “blood and guts” — they’ll be based on bits and bytes.
And they will be much more accurate and faster to carry out.

And, we should look more carefully at outliers generated from
scientific research, he said. “That may be the key to the next


Satava stressed the need for information-based representations of
patients in medicine. “We need to have a new kind of electronic medical
record,” he said. A medical record should include a personal body scan
with data embedded into it. As an example of this, he pointed to the holomer: (HOLO-graphic M-edical E-lectronic R-epresentation)
developed by DARPA. In particular, patients should have such a scan
done when they are well. That way, when they are ill or have an injury, a
new scan can be done and compared against the previous data. When a
person is ill or injured, it is the change in status that is the
important factor.

When this technology is mature, it could allow someone to virtually
test a drug or medical device before actual use. This simulation
technology could be made accurate by marrying it with genomics,
physiological, and other related data.

The government has already considered this technology “from a
different direction” in its virtual autopsy research. The military can
use information gleaned from such virtual autopsies to change its
tactics on the battlefield. It could, for instance, use this data to
develop more effective armor in its vehicles.



As surgical robotic technology evolves, it will become an
increasingly important point of integration for healthcare delivery. The
technology, which Satava explained is better characterized as an
“information system” than a robot, will help save time, increase
efficiency, and collect important data. At present, 95 percent of the potential
of the da Vinci robot is squandered. All of the data that it is
generating when a surgeon moves his hand or looks at an image is thrown
away, he says. “That should be shared over the healthcare enterprise.”

In addition, robots could be used in the operating room to replace scrub nurses,
who pass surgical tools to surgeons. Nurses have more important things
to do, like interacting with patients, Satava explained.


Satava noted that one of the fundamental changes about the
information age is it represents a move away from physical objects to
information and energy. “Energy is going to be a very important part of
the future of medicine,” he reasoned. This form of medicine will be able
to harness the power of plasma (as in an energy cloud) with handheld
instruments at room temperature. In the plasma cloud are charged
particles that can work directly on individual cells and at the
molecular level. The budding field gives physicians the power to turn on
and turn off specific molecules to, for instance, influence coagulation
times and wound healing. It also can be used to kill biological agents.
“At this moment in time, there is no known biological agent that is
resistant to plasma exposure for 30 seconds,” he said. He surmised that
plasma medicine represents one of the “most exciting new areas in
addition to genomics” in modern medicine.
