Tri-Staple™ Technology

Tri-Staple™ technology reloads are designed to work in harmony with the natural properties of tissue before, during, and after stapling. Each reload has a stepped cartridge face that delivers graduated compression and three rows of varied height staples.

The result of that design is a reload that provides greater strength and leak resistance^4,⁸^,Ω,†† across procedures.

Each Tri-Staple™ reload has a stepped cartridge face that delivers graduated compression and three rows of varied height staples. This helps generate less stress on tissue during compression and clamping.^1,2,†,‡

Tri-Staple™ technology’s graduated compression profile and varied height staples allow greater perfusion into the staple line.^3,†

With a stepped cartridge face and graduated staple heights, reloads with Tri-Staple™ technology deliver greater performance across a broad range of thicknesses.^{2,4,5,6,7,§,Ω}

Tri-Staple™ technology reloads are designed to work in harmony with the natural properties of tissue to optimise performance before, during and after stapling. With its stepped cartridge face, Tri-Staple™ technology delivers graduated compression, optimising interaction between the tissue and stapler because it:

Generates less stress on tissue during compression and clamping⁹^,¹⁰^,†,‡
Allows greater perfusion into the staple line¹¹^,†,‡
Provides greater performance in variable thicknesses^2,¹²^,¹³^,¹⁴^,¹⁵^,†

Tri-Staple™ technology improves staple line strength, leak resistance, and hemostasis when compared to the universal reloads.¹⁶
