Speaker 1 (00:01):
Here's your Channel nine first winy weather forecast. Got a
nice day to day, a partly to mostly sunny high
on fifty six, forty six overnight with some clowns. It'll
be gradually cloudy, cloud building throughout the day. Tomorrow windy
as well, but dry seventy eight until seven PM when
severe weather hits the area. It's gonna last for several
days apparently, including a floodwatch all the way through Sunday
(00:23):
sixty one high over or low overnight in a highest
sixty six tomorrow with that rain and storms. Right now,
it's forty degrees in type for traffic.
Speaker 2 (00:32):
From the u SEL Traffic Center. Don't let injury slow
you down, but you see Health orthhopedic Sandsports medicine experts
can help keep you moving. Schedule the same day apployment
at you see health dot Com. Highway traffic continues to improve.
The heaviest southbound seventy five from Sheppard through the Lock
one split, good for an extra eight minutes. In northbound
seventy five break lights out of Erwine Gore into downtown
(00:55):
for an extra seven Chuck Ingram on fifty five, Kara
seen the talk station.
Speaker 1 (01:02):
You say forty five if if you have KCD talk station,
are very happy Tuesday to you and looking forward to
this all morning. It sounds absolutely fascinating, an amazing development
of the field of medicine. Joining me doctor Prashawn Robbie.
He is the CEO of a company called Medior, a
three D and faculty member in the Department of Radiology
at the University of Cincinnati College of Medicine, and he
(01:23):
heart to talk about the use of three D printing
in connection with surgery. Doctor Robbie, it's a pleasure having
in the program.
Speaker 3 (01:30):
Today, likewise glad to be here.
Speaker 1 (01:33):
Now. I guess the gist of this is, you know,
there are CT scans out there, and there are MRIs,
and I know before going into surgery, like for heart surgery,
you rely on those to figure out what is wrong,
I say, with like a microvalve prolapse or there's you
know what cardiac valve repair. That's the surgery you're planning
on doing. But I guess those scans have limitations. But
(01:55):
by using three D technology, you're actually recreating, for example,
a model of the heart so you can see all
elements and aspects of it. Is that is my understanding
correct in that on some minimalist level.
Speaker 3 (02:09):
Absolutely, So what we're doing is essentially describing what the
information in the CP scan in the form of a
three D model, which is much more intuitive for the
surgeon to understand and grasp.
Speaker 1 (02:23):
And so when you build one of these, let's say
let's stick with the heart for example, you build one
of these, it is a mirror image of your patient's heart.
Can you then sort of take it apart and find
out where the anomalies and the problems are. Is you know,
multi piece three dimensional image is like a puzzle kind
(02:45):
of thing.
Speaker 2 (02:46):
Yeah.
Speaker 3 (02:46):
Absolutely, This would have to be planned in a step
called computer ared design. So you would take the information
in the CP scan and kind of segment the anatomy
so the structures that are of interest with the surgeon,
and then yes, there is a way to put it
in the form of puzzle pieces and actually print those pieces,
(03:06):
so the surgeon can have a physical kind of puzzle piece,
you know, to put together and get a better understanding
of that particular patient's anatomy.
Speaker 1 (03:17):
That's just that's absolutely fascinating. Now you've been involved in
three D printing for a long time. Judging from your
CV here that I have in front of me. Has
three D printing gotten to the point where there is that?
I mean, is it? Is it exactly accurate replica? I
just I think you think of pre printing from what
I've seen is sort of rudimentary, and that you know,
this human body is so very complicated and there's all
(03:40):
kinds of things going on in there that are beyond
my comprehension. But is it that precise that you really
literally are looking at what the patient's heart looks like?
Speaker 3 (03:50):
Yeah, the technology has come quite a ways, and yeah,
so if the information is captured in the CD scan
atom to be precise, Yes, the three D printant model
that results from it is very accurate compared to the
CD scan and the patient's anatomy.
Speaker 1 (04:10):
Now can this be in the heart? I understand your
valves and everything goes on. Can this technology be used
in other forms of surgery? I mean, is it is
it sort of limited an application to a heart?
Speaker 3 (04:21):
No, not at all. There's actually a multitude of surgeries
where this technology is now being applied to help surgeons
plan that approach better. This can include liver lacerations, trauma
of the pelvis, jaw fractures, kidney transplants and a bunch
(04:43):
of other procedures where this is having a real impact
in how the surgeries are being planned.
Speaker 1 (04:49):
Now, is it possible at some day to use this
as a diagnostic tool because I guess a CT scan
and an MRI and these images are as good as
the radiologist report comes out. And is it possible that
a radiologist might miss something that could be revealed with
a three D model.
Speaker 3 (05:08):
Absolutely, and it happens all the time. And think of
it this way. So when a surgeon actually looks through
a CT scan, he has to scroll through hundreds of
these slices to mentally map the anatomy in his mind,
and this can take thirty to sixty minutes of his time.
But the same information can be presented in the form
of a three D printed model and can convey that
(05:31):
information in under five minutes because of the intuitiveness. That's
not to say that this will completely replace a radiologist report,
but it's a great adjunct and it just makes it
so much more intuitive and easy to understand. And I've
seen this, you know, with cardiothoracic surgeons where they look
at a model and they know exactly what to do
(05:52):
in two minutes compared to being confused, you know, looking
at the CD scan and not knowing exactly how to
approach that relation.
Speaker 1 (06:01):
How about that? Now, correct me if I'm wrong. But
when you're removing a cancer tumor, is it the most
procedure that they keep scraping away and scraping away until
they find no more evidence of the cancer in the
in the in the scan or in the in the analysis.
Speaker 3 (06:16):
Yes, exactly. And then how a three D printed model
can help in this case is if there's any vasculature
of blood vessels that are involved. Yeah, it can help
the surgeon carefully delineate and understand how those vessels actually
course through and around the tumor, so they can preserve
those vessels while taking away the tumor.
Speaker 1 (06:36):
Oh wow, that's kind of what I was thinking it
could be used for. That's amazing. Now, how long does
it take if you're thinking about a heart procedure of
out procedure, how long does it take to build one
of these three dimensional organs?
Speaker 3 (06:50):
So it can take several last two days with current
technology typically on the order of days. If you want
life size and atomic models, you would have to scale
them down at present to achieve a model on time,
you know, for some of the urgent cases. And that's
where VTRR three d's technology is really kind of changing
the game and enabling same day models for surgeries.
Speaker 1 (07:15):
Fascinating now is are the three D models multi colored?
So for example, if you're talking about a tumor or
a mitro valve, that it would be enhanced with a
different color three D print medium.
Speaker 3 (07:31):
Yes, that is correct, that is three printed capability that
can actually color code different anatomical structures for better visualization
and identification.
Speaker 1 (07:42):
So your company, a Media or three D, did you
invent the technology to convert a CT scan, for example,
into the computer coding to create the three D model,
because that obviously involves some sort of complex process that
again is beyond my understanding.
Speaker 3 (07:59):
Well, Media three technology, my co founder and I invented
a technology that can considerably speed up the process of
actually the printing side, because the actual printing of the
model is the slowest step in the process. I'm going
from a CT scan to a final three dimensional model.
So that's where our intellectual property actually lies. We are
(08:23):
not dealing with the upstream side, the digital side, where
you actually take a CT scan and make a digital
three D model that eventually gets printed. We are dealing
with the downstream, the printing side, which is the slowest
step currently in the workflow.
Speaker 1 (08:37):
If that makes sense, It does make sense. Well, doctor Robbie,
can you just give my listeners an illustration of how
you've employed the three D modeling and you know which
which resulted in you choosing or a doctor choosing a
different surgical outcome or process than they would have done
had they been not had they not had a three
D model.
Speaker 3 (08:59):
Yeah. Absolutely. My mind goes back to a recent case
which involved the chess CT scan up a patient and
the surgeon specifically in this case was an endoscopic surgeon
who wanted to operate on the mitral valve of the patients.
This is the valve that sits between the left upper
(09:20):
and lower chamber of the heart, and in order to
operate on that valve, the surgeon needs to enter the
chest on the right side through a small incision. But
due to the shape of the chest in this particular patient,
you know, and the surgeon termed this as a barrel
(09:41):
chested patient, so because of that, he had a hard
time visualizing how he would actually access the mithrol valve
through that entry, and so he requested a model from
me for this particular case, and when he actually saw
the model, he decided to not operate on the patient
because the access would be much harder than here anticipated
(10:04):
originally from the scan. And so, yeah, it was a
gift to the patient because it avoided a lot of
complications and are potentially a surgical failure.
Speaker 1 (10:14):
Oh wow, doctor Prashaw, Robbie, it's been a real pleasure
talking with you. Congratulations on your involvement in this amazing
technology life saving. It certainly will be, and I imagine
it's going to be sort of widely used very soon
in modern medicine. Modern surgery is just right around the
corner three D printing. Doctor rob just thanks again for
(10:36):
being on the program and taking care of your patients
and coming up with this insanely cool technology. It's been
a pleasure having you on the show.
Speaker 3 (10:44):
Yeah, thank you so much.
