Needle Insertion Force Test Equipment

Needle insertion force measurement is a critical and strategic parameter for device development and quality control professionals in needles and syringes. Insertion force is a key value in characterizing needle geometry and sharpness and in understanding the effects of needle geometry, sharpness, and insertion velocity, viscosity and needle axis frictional forces. Tensile testing also establishes needle-to-hub retention strength and the strength of crimps connecting surgical needles to sutures. Three-point bend tests help assess needle stiffness and the likelihood of permanent deformation on insertion.
