Dispositivo óptico para identificación de regiones tumorales

A surgical device for the identification of tumor regions during a surgical intervention, characterized in that it comprises: an elongated body (12) configured to, during use, bring the distal end of the elongated body (12) into contact with a human or animal tissue to be analyzed, a chip (11) located at said distal end of the elongated body (12), the chip (11) comprising a nanostructured metal surface (111), a first optical fiber (14) located inside the elongated body (12) and configured to deliver a beam of incident light to illuminate the chip (11), a second optical fiber (16) located inside the elongated body (12) and configured to extract a beam of light reflected by the chip (11), wherein, in use of the surgical device, when the chip (11) located at said distal end of the elongated body (12) is in contact with a human or animal tissue to be analyzed, when said beam of light falls on the metal surface nanostructured (111) of the chip (11), the light beam reflected by the chip (11) provides a spectral response that depends on the refractive index of the analyzed tissue, where said refractive index in turn depends on whether the tissue is a necrotic, tumor or peritumoral tissue.
