[0058] Optionally, as Figure 1 and Figure 2 shown, the tongue lifter 200 can be an arc-shaped plate structure with uniform thickness, that is, the arcs of the third arc surface 210 and the fourth arc surface 220 are concentric circles; the tongue lifter 200 is formed at the junction of the first arc surface 121 and the guiding groove 102.

[0059] In some embodiments of the present application, as Figure 2 and Figure 3 shown, the main body part 110 includes a hand-held part 111, a fixing part 112 and a blocking part 113 which are fixedly arranged in sequence from top to bottom in the first direction; part of the side surface of the fixing part 112 is indented inward compared with the side surfaces of the blocking part 113 and the hand-held part 111 to form a groove 114; the orthographic projection of the hand-held part 111 on the blocking part 113 is within the range of the blocking part 113. Among them, the hand-held part 111 provides a grasping position for the operator, which is convenient for operation; the fixing part 112 provides a fixing point for the rigid endoscope intubation assistance device and the trachea. Specifically, medical adhesive tape can be adhered to the fixing part 112 and the trachea and then fixed to the human body; the blocking part 113 is used to abut against the teeth, so as to limit the displacement of the insertion part 120 and prevent the insertion part 120 from being inserted too deeply.

[0060] It can be understood that both the hand-held part 111 and the fixing part 112 can be columnar structures with circular arc depressions, and the parts of the side surface of the fixing part 112 that do not belong to the circular arc depressions are all indented inward to form the groove 114.

[0061] In some embodiments of the present application, as Figure 2 andFigure 3 As shown, the guiding groove 102 can be a uniform arc surface.

The setting of the extension plate 300 can extend the receiving groove 123, provide more receiving space for the tongue, and the extension plate can assist the tongue-lifting plate 200 in performing operations such as tongue-lifting, reducing the operation difficulty.

[0064] In some embodiments of the present application, as Figure 4 shown, the inlet of the channel structure 101 is located on the upper end surface of the main body portion 110, and the outlet of the channel structure 101 is located on the lower end surface of the insertion portion 120.

In this way, it is beneficial for devices such as trachea to slide therein. In some other embodiments of the present application, the channel structure 101 can also be a through hole structure of other shapes, such as a hexagonal hole or an oval hole, etc. The aperture of the through hole structure can also be non-uniform, and the present application does not limit this.

[0066] In some embodiments of the present application, as Figure 5 shown, Figure 5Perspective view of the intubation assistance device according to the embodiment of the present application. In the third direction, the outer edge of the receiving groove 123 extends beyond the outer edge of the channel structure 101; in the third direction, the outer edge of the extension plate 300 extends beyond the outer edge of the channel structure 101. With such a setting, a larger accommodation space is provided for the tongue, which can prevent the tongue from slipping out of the receiving groove 123 and blocking the outlet of the channel structure 101, thus facilitating operations such as gas delivery and sputum aspiration.
