BIOSPECTRUM | SEPTEMBER 2018 | http://www.biospectrumindia.com l SCIENCE NEWS^45
A group of scientists at the Indian Institute of Science
(IISc), Bengaluru has developed a low cost simulator
for endoscopy, a medical procedure to examine
the interior of a body by inserting a tube with an
attached camera. The objective of the simulator
called EndoMimyk is
to train clinicians with
graphic visualization.
Such a simulator can
help bridge the spatial
and temporal gap
between the patient
and the doctor and is
useful in remote medical
diagnosis and treatment.
EndoMimyk is not the
first such simulator available. But the one developed
by the IISc group is a novel system consisting of
a haptic interface, VR models and instrumented
tools. According to the researchers, haptics is a fast
emerging technology that offers immersiveness while
interacting with virtual environments.Researchers at the Indian Institute of Technology,
Delhi have designed and fabricated a low-cost,
and light-weight polymeric polycentric prosthetic
knee joint with energy-efficient gait option. The
researchers took seven years to come up with
this knee joint design. It
has been tested clinically
at Department of Physical
Medicine and Rehabilitation,
Government Medical College,
Thiruvananthapuram.
According to the researchers,
the result showed that
the patient using the new
prosthetic walked closer to
natural gait pattern compared to the conventional
ones. The energy expenditure was also reduced.
The prosthetic is made up mainly of polymeric
material through injection molding technique and
is polycentric in design consisting of an upper
part, a lower part with pylon adaptor, a middle
bar, a side bar and connecting bolts. It weighs a
mere 350 grams.
