Abstract
A device for measuring elastic properties, comprising a long bar-like probe base () and probes () fitted to the probe base () driven as to be pressed against and withdrawn from a living body tissue. The probes are so formed that generally semi-spherical contact balls () having stress detection bases () are fitted to the ends of leaf strings () and stress detection sensors () are disposed on the stress detection bases (). Light-receiving elements are fitted to the opposite side of the leaf displacement sensors (). The stress sensors () and displacement sensors () are connected to the device body through signal lines (), respectively. The profile of the displacement of the tissue is calculated and displayed in a manner indicating correlation with stress.
