An endotracheal tube-inserting deviceAn endotracheal tube-inserting device (1) comprises a stylet part (3) and a handle part (2) for operating the stylet part (3). The stylet part (3) has a proximal stylet end part (7) with a proximal stylet end (8) and an opposite curved distal stylet end part (5) with a distal stylet end (5a). The distal stylet end part (5) has an extension in form of a bendable tip part (6). A first string-operating member (10) is operatively connected to at least a first securing position (54a) at the bendable tip part (6) by means of a first string member (14), and a second string-operating member (11) is operatively connected to at least a second securing position (54b) at the bendable tip part (6) by means of a second string member (15). The bendable tip part (6) has a bendable proximal tip part (18) that extends into a bendable distal tip part (19) via a stringguiding member (46).
