The invention is applicable in medicine, especially in anaesthesiology, otorhinolaryngology, neonatology, anatomy, forensic medicine, etc. The spatula for laryngoscope allows direct measurement of anatomical structures, as well as calibration of optical video and photo equipment. It consists of a body (1), under which the blade is situated (3). Onto the blade (3) there is a longitudinal (4) transverse (6), geometrical (7) and colour (8) scale, through which the longitudinal and transverse dimensions of the studied anatomical structures are determined, as geometrical corrections and colour calibration of the images from the optical equipment are possible. By using the spatula for laryngoscope during direct examination of the anatomical structures increases the -accuracy and quality of the diagnostic and treatment procedures.
