Multifilament versus Monofilament Suture Strength
Testing
Name: Adam Lafleur
Class: BE 210
Hypothesis
Monofilament suture material will have a greater tendency to slip under tension than braided multifilament sutures and will therefore exhibit a significantly lower failure stress.
Experimental
Objectives
·
To quantify planar displacements and strains,
and determine suture technique performance for resisting separation under
tensile load
·
To
quantify ultimate stress at failure and deformation under uniaxial loading.
Educational Objectives
· To understand the effects of slippage by comparing a standard (non-knotted) deformation curve to each trial.
· To understand correct tie off procedures for suture completion and the best techniques to ensure consistency and uniformity.
