Circular staplers
EEA™ circular stapler with Tri-Staple™ technology
<p>The EEA™ circular stapler with Tri-Staple™ technology is designed to support anastomosis during surgical procedures.</p>
Features
A study evaluating the performance of circular staplers
Read how the EEA™ circular stapler with Tri-Staple™ technology outperformed the Ethicon Echelon Circular™* powered stapler — with 140% greater perfusion into the staple line.
See how Tri-Staple™ technology stacks up to two-row circular staplers
Our EEA™ circular stapler delivers three rows of varied height staples for consistency across a broad range of tissue thicknesses.◊,¶,3−5 Together with a sloped cartridge face, Tri-Staple™ technology also delivers:
60% reduction in firing force versus Ethicon™* manual CDH circular staplers¶,††,7
The same inner/outer lumen diameters as DST Series™ technology¶,3
Designed for your colorectal surgical procedures
Our EEA™ circular stapler with Tri-Staple™ technology was designed to support anastomosis with:
A sloped cartridge face, that puts less stress on tissue during compression and clamping¶,††,‡‡,6
Louder audible feedback during unclamping compared to Ethicon™* manual CDH¶,‡‡,7
A Tilt-top™ anvil to facilitate removal
We developed features like those because procedures — and tissue thicknesses — vary.
