The present invention discloses an endotracheal tube shape modulating device (1000) comprising a proximal casing (100), from which a rigid hollow member (400) is extending in a forward caudal direction, a directing mechanism (600) attached at the distal end of the rigid hollow member (400) and an operating handle (200) extending from the casing (100). The operating handle (200) is pivotally connected to the casing (100) such that it may pivot around a operating handle pivot axis (250) from a forward position in a sagittal relaxed state to a backward position in a sagittal compressed state. The operating handle (200) is mechanically connected to the directing mechanism (600) by means of an upper directing wire (510), attached at its proximal end to an upper attachement point (210) of the operating handle (200) and at its distal end to a point on the ventral side of the directing mechanism (600), and by means of a lower directing wire (515), attached at its proximal end to a lower attachment point (215) of the operating handle (200) and at its distal end to a point on the dorsal side of the directing mechanism (600). The operating handle pivot axis (250) is located dorsally relative the upper attachment point (210) and ventrally relative the lower attachment point (215).Linvention porte sur un dispositif (1000) permettant de modifier la forme dun tube endotrachéal, lequel dispositif comprend : un boîtier proximal (100) à partir duquel sétend un élément creux rigide (400) dans une direction caudale antérieure un mécanisme de direction (600) attaché à lextrémité distale de lélément creux rigide (400) et une poignée fonctionnelle (200) qui sétend depuis le boîtier (100). La poignée fonctionnelle (200) est reliée pivotante au boîtier (100) de telle manière quelle peut tourner autour dun axe de pivotement de poignée fonctionnelle (250) depuis une position antérieure dans un état sagittal relaxé jusque dans une position postérieure dans un état sagittal comprimé.
