Устройство для идентификации биологической ткани, содержащее оптически соединенные источник оптического излучения, светоделитель, оптический световод, имеющий дистальный и проксимальный концы, фотодатчик, выход которого соединен с видеомонитором, отличающееся тем, что дистальный конец световода установлен в павильоне медицинской иглы с возможностью удаления из нее, полированный торец дистального конца световода совмещен с концом иглы и выполнен под углом α, определяемым соотношением arcsin (1/n2)<α<arcsin(n1/n2), где n2 - показатель преломления материала световода, n1 - показатель преломления биологической ткани.A device for identifying biological tissue containing an optically coupled optical radiation source, a beam splitter, an optical fiber having distal and proximal ends, a photosensor whose output is connected to a video monitor, characterized in that the distal end of the fiber is installed in the pavilion of the medical needle with the possibility of removal from it, polished fiber end of the distal end aligned with the end of the needle and is configured at an angle α, defined by the relation arcsin (1 / n 2) <α <arcsin (n 1 / n 2) where n 2 - figure refracted I material of the fiber, n 1 - the refractive index of the biological tissue.
