Bi-spectral peroperative optical probe

摘要

The probe has light sources (1, 2) emitting a light beam for lighting a biological tissue surface (3), whose zone (30) i.e. marked zone is fixed by a fluorescent die. An optical device e.g. camera, has a charge couple device photo-sensitive surface (7), and is connected to an image processing device (8) processing an image issued from the photo-sensitive surface. Different optical units of the optical device lights the part of the biological tissue surface that corresponds to the marked zone identified by the image processing device.
