Virtual Reality, Robotics And the Future Of Surgery
In the future,
advances in medical technology and surgical methods may help to save and
improve lives. As a result, some surgeons are ill-prepared to conduct
complicated procedures and some patients are put in danger because our existing
system of educating and evaluating surgeons has fallen behind the speed of
innovation. When used in training, virtual reality technology has the potential
to help solve these issues and improve abilities.
When it comes to
surgeons, we observe a distinct difference between their residency and
fellowship training. Are some residents intrinsically better surgeons than
others? It's also possible that these variations might be attributed to
differences between trainees' clinical circumstances and autonomy levels. As an
example, one surgeon may have conducted dozens of hip arthroscopies throughout
their training, whereas another may have only performed one or none.
Is it possible to offer the correct type of training
standardized? A second question is how can we objectively determine if surgeons
can perform well before they begin independent practice?
Many surgical
residency programs struggle with accurate and objective assessment. When it
comes to evaluating residents' performance, these programs don't often use
standardized exams with quantifiable standards or "scores" for
surgical competence. If you're trying to define a "good surgeon," it
might be difficult to distinguish bedside demeanor, work ethic, and technical
skill from surgical expertise and proficiency.
Additional problems
for surgeons include insufficient opportunity to practice new skills,
particularly those connected to new medical technologies. The medical device
business will send surgeons to a one or two-day training course to learn about
a new gadget. It is rare for surgeons to continue honing their abilities after
their first training. As a result, surgeons are forced to update their
knowledge "on the fly" in an operating room after training for four
or six months.
These deficiencies in
training and assessment are raising the degree of risk for patients and the
surgeons who care for them, with significant implications. Take a look at these
numbers:
According to a recent
University of Michigan research, 30 percent of surgeons are unable to operate
autonomously after completing a residency program.
Death rates for
bariatric surgeons with lower competence levels were 5x greater than those with
better skill levels, according to a study published in the New England Journal
of Medicine in 2010.
Worldwide, surgical complications
affect 7 million patients each year.
There are many reasons
to be concerned about the current state of affairs, but the aging baby-boomer
population and predicted surgeon shortage might make things far worse.
VR (virtual
reality)-based training systems provide an exciting answer to a number of these
difficulties. Computer technology is used to create a virtual world that
immerses the user in the experience, according to the definition of virtual
reality (VR). Through immersive, hands-on training that replicates an operating
room setting, these platforms address the skills gap directly. On-demand,
portable training is available on VR devices at any time and anywhere.
To make matters worse,
VR-based technologies integrate "checklist-style" assessment methods
to objectively quantify surgical skill, placing the procedure beyond human
subjectivity. These technologies provide surgeons with a detailed view of what
they are doing right and where they may improve.
Worldwide, hospitals
and colleges have embraced virtual reality certification training for years, but there has been little study
on the usefulness of VR until recently. Recently, UCLA's David Geffen School of
Medicine conducted research to address that need. Study participants who
underwent virtual reality (VR) training performed 230 percent better than those
who used traditional training techniques.
Participants were
randomly divided into two groups: a standard training group and one that
received VR instruction on the Osso VR platform to a predetermined level of
competency over two weeks. All participants had to conduct intramedullary
nailing of the tibia (one of the bones that run from the knee to the ankle) to
heal the fracture. An unblinded observer assessed their performance on a
"sawbones" model that was created artificially.
With a 230 percent
gain in total score based on a five-point evaluation scale, VR participants
earned considerably higher scores in all areas compared to the
traditional-trained group. Those who were VR-trained performed the operation on
average 20 percent faster than those who had been trained in traditional
methods. In addition, they completed 38 percent more steps properly on the
procedure-specific checklist than their counterparts. Both of these findings
were statistically important.
Assistive technology
Instead of putting a
surgeon in a simulated world, augmented reality augments and overlays the real
clinical setting. You may choose from a wide selection of technologies
including Pokemon Go, HoloLens, and Google Glass.
For instance, here's
an example of how augmented reality may be used When faced with a complicated
or unusual situation, surgeons typically seek the counsel of an expert. Before
or after the treatment, these specialists are commonly contacted through email,
phone, or text message. Experts can view what the surgeon sees and give
personalized assistance throughout a surgery via telementoring, a popular usage
for AR.
Mobile apps
Surgical safety and
efficiency may be improved using relatively simple technologies.
Miscommunication, danger, and inefficiency in the operating room can be caused
by coordinating a surgical team in the operating room. It is common for team
members to come and go throughout a process, which might lead to confusion
regarding what is expected of them.
In order to solve this
problem, ExplORer Surgical has developed a simple-to-use solution. During
surgery, each member of the surgical team has an iPad with individualized
instructions as to what stage of the procedure the team is at any given time.
As soon as a "conductor" is ready to go on to the next phase, he or
she swipes the screen.
Wrapping up
New means of
delivering surgical education are needed in today's continuously changing
medical world. To guarantee that our surgical workforce has a constant level of
quality and standardized skillset, we must codify our technical evaluation
process in order to more objectively examine surgeons' skills.
Due to a stressed
surgical-educational system, fast medical innovation, and an impending
physician shortfall, virtual reality (VR) may be an important instructional
tool to supplement surgeon training and continue to provide the best treatment
to patients.
