Embodiment Construction

[0032] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings of the embodiments.

[0033] The movable laryngeal opening guide device of the present invention such as Figure 3-Figure 5 As shown, the same as the prior art, it also includes a handle 20 and a lens duct 21. The difference is that it also includes an arc-shaped first laryngoscope blade 22 and a second laryngoscope blade 23. The first laryngoscope The end of the blade 22 is connected to the bottom of the handle 20, and the second laryngoscope blade 23 is arranged below the first laryngoscope blade 22 and can form a relative movement with the first laryngoscope blade 22 through the lifting mechanism 24 arranged on the handle 20. The laryngoscope blade 23 is a hollowed-out structure, specifically, there is a front part in it which is adapted to the shape of the front part of the first laryngoscope blade 22 and is used for the front ...

Abstract

The invention relates to a movable laryngeal cavity distraction guiding device which comprises a handle, a lens pipeline, a first laryngoscope blade and a second laryngoscope blade, the first laryngoscope blade and the second laryngoscope blade are in an arc shape, and the tail end of the first laryngoscope blade is connected to the bottom of the handle. The second laryngoscope blade is arranged below the first laryngoscope blade and can move relative to the first laryngoscope blade through a lifting mechanism arranged on the handle, and the second laryngoscope blade is provided with a penetrating hole which is matched with the front middle portion of the first laryngoscope blade in shape and enables the front middle portion of the first laryngoscope blade and the second laryngoscope blade to be combined into a whole. The front end of the lens pipeline is arranged along the bottom of the first laryngoscope blade. Through the first laryngoscope blade and the second laryngoscope blade which can move relatively, the swollen epiglottis and the surrounding swollen throat side wall mask can be opened and separated so as to expose the epiglottis, the throat inlet and other positions needing to be observed, and the position relation between the swollen epiglottis and the second laryngoscope blade can be seen clearly through the lifted lens. And the epiglottis is lifted by the second laryngoscope blade, so that the glottis is smoothly exposed.

Description

technical field [0001] The invention relates to a laryngoscope device, in particular to a movable laryngeal cavity distraction guiding device and a movable method thereof. Background technique [0002] Existing video laryngoscopes are all equipped with a laryngeal cavity expansion guide structure, which usually includes a handle, an arc-shaped laryngoscope blade arranged at the lower end of the handle, and a lens duct arranged along the bottom of the laryngoscope blade. When it is placed in the mouth, slowly push the spatula to reach the base of the tongue. The epiglottis can be seen through the laryngoscope camera through the lens duct, and then go through the epiglottis to the glottis for inspection or treatment. [0003] Since the traditional lens pipes are all fixed on the lower end of the blade of the laryngoscope, there is an obvious blind area of ​​viewing angle. Therefore, the patent with the notification number CN210810930U discloses a visual laryngoscope with repla...
