Needle Insertion Force Measurement: Multi-needle Test Fixture

In order to ensure patient safety, needle insertion force measurement is a critical parameter for needle developers and quality control professionals in the medical device industry. In recent years, researchers and manufacturers have invested significant resources in developing surgical simulation and preoperative planning tools, which require parameters such as needle insertion force. Insertion force is also a key value in characterizing needle geometry and sharpness, and in understanding the effects of velocity, viscosity and frictional force along the needle axis during insertion into soft tissues.

With a wide variety of needles available, fixturing is unique to the objective and application of the tests and results. Test configurations, such as our multi-needle test fixture, reduce testing time in needle production and quality control processes. We offer a robust single-needle fixture that provides significant advantages for research and development.
