Abstract
The multiple disciplines such as materials science, engineering and biomedicine have facilitated the development of different types of surgical suture materials with multifunctionalities. In this work, thirty-six suture thread material samples were collected from four different companies representing three different materials (most commonly used): silk, VICRYL and polypropylene with three different yarn counts (4, 3.5 And 3 metric). Practical statistical science serves to support the practical analysis of experimental work products and the various relationships between variables to achieve the best sampling performance with the functional purpose generated for it. Analysis of the imported sutures shows that VICRYL sutures had the highest tensile strength, toughness, knot tensile strength and knot toughness, followed by polypropylene and silk. As yarn counts, weight and diameter increase, its tensile strength and toughness increase while its elongation and knot tension decrease. The multifilament yarn construction (silk and VICRYL) scores higher compared to the monofilament construction (polypropylene), resulting in increases in tenacity, toughness, knot tensile strength and knot toughness.
