Sutures are used in a variety of different surgical procedures to close wounds and aid in tissue healing. They are manufactured from a variety of different absorbable and unabsorbable materials, and may be a single filament or braided with or without a coating. Tensile strength is a critical measure of performance during and after surgical procedures. The strength of different knotting techniques must also be evaluated. Precise, consistent and reliable measures of strength and strain are essential for product development and quality control.
For this application we recommend a 3345 frame with a 1 kN load cell and 1 kN capacity pneumatic cord and yarn grips. These cord and yarn grips are instrumental to successfully conducting tensile tests on suture material for the following reasons:
