DEVICE AND METHOD FOR TESTING TISSUE

摘要

An intraoperative tissue assessment device (10) allows a surgeon to assess certain mechanical properties of tissue samples (17). The device (10) includes a cavity (28) for housing and securing at least a portion of the tissue sample (17) in communication with a pressurization source to inflate a portion of the tissue forming a dome of tissue having a height axis substantially perpendicular to the tissue sample secured within the cavity. A source of illumination (32) projects collimated light rays illuminating the dome of tissue and creating a Moiré fringe pattern, which may be used to determine the degree of anisotropy of the tissue sample when viewed through a viewing port (26) arranged substantially directly above the dome of tissue.
