Thorough biomechanical analysis of arterial response to EasyEndo-Lite staple rotation: a simulation study in abaqus

Understanding instrument-tissue interaction is vital for safe surgery. We used Abaqus to simulate arterial response to EasyEndo-Lite Staple rotation, focusing on abrupt motion and strain-rate effects. Sudden angular rotation produced high strain rates and peak stresses in the clamped arterial segment, reaching 1.4 MPa at 15° and ∼3.7 MPa at 30°. Rapid cessation of rotation increased forces by up to 28%, indicating elevated damage risk. The simulations provided detailed deformation and stress data across scenarios, demonstrating how optimizing instrument design and operating parameters could substantially reduce tissue trauma and improve surgical outcomes.
