This presentation is about new technologies that come handy for doctors to do medical things easier and better. It was collected as a student presentation in university.

2. NEW ASSISTANTS FOR SURGEONS

4. 3D PRINTING

5. Old…
New!
Cortex

6. • The first is 3D printed casts with ample air spaces to allow the
victim’s skin to breathe and reduce the itching that usually surfaces
a while after the cast is put on
• Jake Evill dubs his project, Cortex, an exoskeleton rather than a
cast. First, an x-ray of the injured limb is performed. Next, a scan of
the exterior of that same limb is made. Finally, based on both of
the above, a suitably stiff-but-flexible 3D print is made. The result
is customized to the needs of the user for both recovery and
comfort

7. 3-D PRINTED PROSTHETICS THAT LOOK FIT
FOR A SCI-FI WARRIOR

9. SO CAN WE MAKE IT
COMPLETELY REALISTIC ?

10. THERE IS A PROBLEM!
What about feelings then?!....

11. ARTIFICIAL SKIN
• One of the many challenges of adjusting to life with a prosthetic limb is that the new
limb lacks sensation; patients can’t feel where their artificial limb is in space, or what it’s
touching, so they have to work mostly by sight. Adding a sense of touch could make
controlling prosthetic limbs easier and more natural – but that’s a challenge for
engineers.
• The nerve endings in human skin are very sophisticated, low-power circuits that turn
physical pressure on the skin into a digital signal in the brain. Those signals in the brain
create our sense of touch. It’s difficult to build an electronic version of such a complex
system, but Stanford University electrical engineer Benjamin C. K. Tee and his
colleagues believe they’ve made a step in the right direction. They have developed a
receptor system called Digital Tactile System or DiTact which could one day give
prosthetic limbs artificial skin with a sense of touch.

12. Digital Tactile System
DiTact’s sensors are sensitive to the same range of pressure as human skin. “It is sensitive to very light touch, such as the weight
of a grain of salt,” said Stanford University chemical engineer Zhenan Bao, a co-author on the DiTact study. Using carbon
nanotubes, his team had previously developed a very sensitive pressure sensor that was also flexible enough to use in artificial
skin. Now they just needed the sensors to turn pressure into a digital signal to neurons in the brain.

13. MAKING ORGANS WITH 3D PRINTERS

14. SAVING LIVES WITH 3D PRINTING

15. HEART!
4-Year-Old Girl’s Life Saved
Thanks to 3D-Printed Heart
Model

16. ADAENELIE GONZALEZ AT MIAMI CHILDREN’S HOSPITAL
Four-year-old Adaenelie Gonzalez has had quite a journey. Born with a rare congenital heart disease
called total anomalous pulmonary venous connection, she already had two open heart surgeries
before she was six months old. The problem was that the veins and arteries to and from her heart
were missing, meaning she wasn’t getting enough oxygen into this vital organ.
Her parents were out of hope that the doctors would be able to help her. Her doctors at Miami
Children’s Hospital thought her days were numbered, until they could better imagine the procedure
with a 3D-printed heart model in their hands.

17. When planning a third, unprecedented open heart surgery, Director of Cardiovascular Surgery Dr. Redmond
Burke and pediatric cardiologist Dr. Nancy Dobrolet were able to visualize the procedure with a 3D-printed
heart model, based on a scan of Adaenelie’s heart and designed using Materialise’s Mimics Innovation Suite
software. This model is an exact replica of her heart, showing every little nerve and artery. After seeing the
model, Dr. Burke said, “This is beautiful. I think I can save her because I can see what her heart is going
to look like when I open her up.”

18. 3D PRINTED DRUGS TO PERSONALIZE MEDICINE
• While the institute has patented 3D printing technology for applications in various
fields, Aprecia Pharmaceuticals has the exclusive rights to the technology for
pharmaceutical use. The company successfully developed the world’s first 3D-
printed drug last year. Spritam is a drug for treating seizures in epileptic patients
and was printed by sandwiching a powdered form of the drug between liquids
and then bonding them.

20. THE NEWEST DEVICE RELEASED

21. $49,000

22. Vitastiq is preparing to launch a new portable
device that measures your body’s vitamin
content by passing a sensor over your skin. It
works with a smartphone app that shows you
whether you need more vitamins and
minerals.

23. ORIGAMI USAGE IN SURGERIES

24. ORIGAMI USED TO MINIATURIZE, IMPROVE
SURGICAL TOOLS, MEDICAL IMPLANTS

25. ROBOTIC SURGERY

26. DA VINCI
SURGICAL
ROBOT

27. WHAT IS DA VINCI SURGERY?
With the da Vinci Surgical System, surgeons operate through just a few small incisions.
The da Vinci System features a magnified 3D high-definition vision system and tiny
wristed instruments that bend and rotate far greater than the human hand. As a result,
da Vinci enables your surgeon to operate with enhanced vision, precision and control.
The da Vinci System represents the latest in surgical and robotics technologies. Your
surgeon is 100% in control of the da Vinci System at all times. da Vinci technology
translates your surgeon’s hand movements into smaller, precise movements of tiny
instruments inside your body.
