Surgical Stapling

Our surgical stapling portfolio addresses the challenges of tissue thickness, tissue movement during firing, staple line security, and tissue tension with the objective of providing greater stapling precision in surgery.

Surgical Stapling
Ethicon Logo

The ECHELON CIRCULAR Powered Stapler reduced leaks by 61% at the staple line compared to the Medtronic DST SeriesTM EEATM Stapler.1*

33%

Gripping Surface Technology provided gentler handling with a 33% reduction in compressive forces on tissue.6#

37%

Push button firing increased stability with 37% less distal tip movement during firing.7##

3D

Designed with offset closure of​ the staple legs, 3D Stapling​ Technology evenly distributed​ compression to reduce potential​ leak paths.
