Advances in Usability and Performance of a Linear Stapler-Cutter

Background: Linear staplers are widely utilized in a variety of surgical procedures to cut, remove, and connect tissue with technology that is constantly evolving and improving. The Echelon Linear Cutter was recently launched with improved tissue handling via Gripping Surface Technology (GST), advanced 3D staple formation, and an ergonomic design with locking halves for one-handed operation. This study was performed to compare the new stapler to the previous version, the Proximate Linear Cutter. Methods: Comparisons between the two staplers were performed in porcine models to evaluate staple formation, compression uniformity, leakage at the staple line, and tissue grasping force. Surgeons evaluated the usability and performance of the Echelon stapler in a simulated procedure. Results: Compared to the Proximate stapler, the Echelon Linear Cutter had significantly lower rates of malformed staples in thin (colon) and thick (stomach) tissue. In addition, results showed the new stapler had more uniform compression, higher tissue grasping force, and higher leak pressure at the staple line. Surgeons found the new stapler easy to assemble, control, place with one-hand without assistance, and capable of capturing thick tissue. Conclusion: In preclinical testing, the new Echelon Linear Cutter with GST, 3D staples, and locking halves allowing for one-handed device placement offers improved tissue manipulation, stapling and ergonomics compared to the previous stapler. Clinical testing is necessary to determine whether these benefits extend to patient outcomes.
