Abstract
A highly accurate, high resolution, frictionless, gravity compensated tissue elastometer. A system that offers high resolution and accuracy measurement of the different properties both in vivo and in situ, through real-time, force and deformation and displacement measurement.
Claims8
A tissue elastometer comprising:
- an end-effector;
- an actuation systems that includes feedback equipped piezoelectric actuation as an source of rectilinear motion generator;
- magnetic actuation system composed of combination of magnets;
- a centrally align, free-floating shaft located between said piezo actuator and said end-effector;
- and
- a capacitive distance measurement tool intended to adapted to measure and control the relative motion between said free-floating shaft and said piezoelectric actuator system wherein capacitance changes may be measured by the motion of said piezo or said free floating shaft as it is attached to them on both ends.
