S-shaped Visible Hard Intubation Core

A S-shaped visible hard intubating stylet, comprising a LCD display, a handler and a hollow hard stylet;

• the handler has one end connecting to the LCD display and the other end connecting to one end of the hard stylet;
• characterized by that, the other end of the hard stylet is provided with a camera and a light emitter therein, which are connecting to the LCD display, respectively;
• the hard stylet is formed to comprise, from one end to the other end, successively, a first linear section, an arc-shaped section, a circular arc-shaped section and a second linear section;
• the arc-shaped section along with the circular arc-shaped section exhibit a shape of “S”;
• a tangential direction of a tail end of the circular arc-shaped section that is adjacent to the arc-shaped section, and an axis direction of the handler, have an included angle which is ranging from 2° to 20°;
• the circular arc-shaped section has a circular arc radius which is ranging from 45 mm to 75 mm;
• the circular arc-shaped section has a circular arc corresponding to a central angle which is ranging from 60° to 80°;
• the second linear section and the axis direction of the handler have an included angle which is ranging from 50° to 70°.
