Problem
Addressed

To design a hand-held portable medical device for invitro assessment of mechanical properties of bone. These mechanical properties of bone are very useful in medical applications as well as for research community. Current methods X-Ray, DEXA, CT, X-Ray scan are not precise and DEXA scans are expensive and time consuming and cause radiological exposure to body.

About the
Technology

  • An impact-trigger mechanism play relationship for load-displacement in minimally deformed bone material, and mathematical modeling for properties calculation used are like the indentation method for viscoelastic material as bone is.
  • Conventionally there is no portable device available for measurement of mechanical properties of bone in- vitro, and other conditions
  • A hand-held lightweight portable indenter.
  • Minimally invasive measurement device.
  • Measurement areas below millimeter scale.
  • Direct implementation to subjected areas.
  • More accurate than DEXA bone quality score as direct measurements of mechanical properties.
  • Less skilled professionals can operate easily.

Application Areas & Use Cases

  • Measurements of Bone quality parameters; modulus, hardness, stiffness.
  • Portable indenter instruments for in-vitro and other conditions.
  • Helpful to less skilled personal usage.
  • For Clinicians, Doctors, Orthopedicians, Engineers, Scientists and Researchers.
