Olympus | EZ Shot 3 Plus
Olympus's updated EUS needle
makes it much easier and
more efficient to perform endo-
scopic ultrasonically guided
fine needle aspiration (EUS-
FNA) of lesions within the GI
tract. In some areas of the body
— notably the pancreatic head
— EUS-FNA can require the
endoscope tip to be inserted at
a curve, often making it difficult
to pass a needle through the
scope's channel, or causing the
needle to bend and become
useless. Instead, the EZ Shot 3
Plus is designed to always stay
straight, even after multiple
passes.
The needle is made of nitinol, a material that holds its shape, and
its tip is extremely sharp for precise aspiration. The design means
that even if the tip of the scope is bent, the needle will consistently be
deployed straight, which makes its trajectory much more predictable
for the physician. The sheath of the needle is also designed to reduce
friction, so physicians can pass the needle smoothly down the scope
with minimal effort. These features could help shave time off of EUS-
FNA procedures, since the physician won't have to delay a procedure
to replace a bent needle, or spend extra time trying to maneuver the
device down a curved scope.
