Description

Nasal trachea cannula direction hook

Technical Field

The utility model belongs to the technical field of medical auxiliary instruments, relates to an auxiliary device for a transnasal tracheal intubation, and particularly relates to a direction auxiliary device used in the transnasal tracheal intubation in an oral operation of a child.

Background

The transnasal tracheal intubation is a tracheal intubation method for meeting the requirements of some special operations in the field of anesthesia, common oral surgery such as pediatric multiple caries root canal treatment, mandibular tumor surgery, mandibular fracture surgery and the like, and common transnasal visible tracheal intubation and nasal blind tracheal intubation.

Blind nasal endotracheal tubes are relatively long and have many complications and are therefore currently in short use. At present, the tracheal intubation organ is viewed through the nose, namely, the tracheal catheter is firstly inserted into the nostril of a patient under the anesthesia state to the pharyngeal cavity, then the epiglottis is picked up by using a visual laryngoscope, the head end of the tracheal catheter exposed in the pharyngeal cavity is clamped by the tracheal intubation forceps, and the tracheal intubation is slowly sent into the glottis to complete the tracheal intubation. However, when the mouth opening degree is small or the pharyngeal cavity is narrow, the front end of the tracheal intubation forceps affects the visual field, so that intubation is inconvenient or difficult, the air sac part of the tracheal catheter is repeatedly clamped, the air leakage of the air sac of the tracheal catheter and pharyngeal cavity bleeding caused by operation are caused, and the life safety of a patient can be seriously threatened.

Therefore, there is a strong need for a direction assistance device for use in a transnasal endotracheal tube that can control the direction of the head end of the endotracheal tube in the pharyngeal cavity, and that satisfies the needs of less damage, no visual field impact, and fewer complications.
