Description

Tracheal intubation device and application method thereof Technical Field The invention relates to the technical field of medical instruments, in particular to an endotracheal intubation device and a using method thereof. Background In anesthesia, emergency and intensive care, airway management is a critical operation, and its core goal is to quickly and effectively establish ventilation or intubation channels while ensuring patient safety. The instruments commonly used in the clinic today are in various forms of construction including, but not limited to, laryngeal mask structures, oro-intubation instruments and other intubation aids. First, classical laryngeal masks typically include a laryngeal mask body and an inflatable mask cuff, wherein the mask cuff is attached around the laryngeal inlet after placement to form a ventilation channel over the glottis, such laryngeal masks have the advantage of being simple to place and less irritating and are primarily used to maintain ventilation. However, the classical laryngeal mask has a heavily ventilated function, and in some cases although smooth intubation can be accomplished by the experience of the operator, the success rate and repeatability of intubation are limited due to the lack of a stable, dedicated intubation channel structure, and it is difficult to stably and reliably support the translaryngeal mask endotracheal intubation. Secondly, the intubate formula laryngeal mask has improved on classical laryngeal mask structure basis, and its inside is provided with intubate passageway for the operator can put into the endotracheal tube through intubate passageway after the laryngeal mask is in place, thereby realizes the trachea cannula. In particular, intubating laryngeal masks are mainly intubated in two ways, one blind-insertion, i.e. the operator pushes the endotracheal tube according to experience and anatomy, and the other auxiliary way of the fiberoptic bronchoscope, i.e. guiding by means of additional equipment. Therefore, although the intubate type laryngeal mask expands the application scene of the laryngeal mask to a certain extent, the direction of an intubate channel is usually a fixed structure, in actual operation, fine direction adjustment capability is lacking in the intubate process, when the distal end of the intubate channel is not well aligned with a glottic axis, an operator can often finish operation only by repeatedly adjusting the position of the whole laryngeal mask or trying intubate for many times, and operation difficulty and potential risks are increased. Finally, visual airway devices, such as visual laryngoscopes, expose the glottic area mainly through imaging to assist the operator in judging the intubation timing, thereby improving the problem of insufficient glottic exposure under traditional blind cutting conditions. However, the structural function of such visual airway devices is focused on the visual presentation of the glottis, and the auxiliary channel for intubation through which the air supply tube passes or is limited is not formed, so that the air supply tube is usually required to be independently propelled outside the device in intubation operation, and the intubation direction is mainly finished by the hand operation experience of an operator and the adjustment of the overall posture of the device. That is, although visualization of the airway device improves the visualization of the glottis to some extent, its role is mainly limited to providing visual information of the glottis area, it is difficult to form structural constraints on the insertion path of the endotracheal tube during intubation, and the effect of direct or active adjustment of the direction of the intubation channel cannot be achieved. Therefore, the prior art has a common defect that an integral technical scheme capable of comprehensively utilizing visual information in the intubation process and actively, finely and controllably adjusting the intubation channel is not formed, so that the effective guiding of the endotracheal tube insertion path is realized. Further analysis is carried out in combination with the mechanism angle realized by the technology, the prior relevant apparatus for airway management is difficult to realize the fine control on the direction of the cannula passage in the cannula process, and mainly comes from the limiting factors of the following technical mechanism layers: 1. the direction of a cannula passage of the conventional cannula device is usually a fixed structure, and fine adjustment of the cannula passage is difficult in the cannula process; 2. when the cannula passage is not well aligned with the glottic axis, the cannula passage is often required to be adjusted by integrally moving the instrument or repeatedly trying to insert the cannula, the operation mode is relatively rough, and the operation complexity and the potential risk are increased; 3. although some of the prior art introduces a visual means,
