Circular staplers

EEA™ circular stapler with Tri-Staple™ technology

The EEA™ circular stapler with Tri-Staple™ technology is designed to support anastomosis during surgical procedures.

Description

Get greater leak protection†,‡,1 and greater perfusion allowed into the staple line†,§,2 with the EEA™ circular stapler with Tri-Staple™ technology.

That means you can have consistent performance in circular stapling over a broad range of tissue.◊,¶,3−5 You and your patients can benefit from:

  • 80% fewer leaks versus Echelon™* Circular™* powered stapler†,‡,1

  • 140% greater Prefusion versus Ethicon Circular™* powered stapler†,#,2

  • Less stress on tissue during compression and clamping¶,∆,∞,6

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.
