Endotracheal intubation refers to that the endotracheal tube by is special inserts the technology of trachea by oral cavity or nasal cavity through glottis. It is usually used in needing the treatment of patient with general anesthesia or Cavity in Critical Patients clinically. This technology can prevent patient from occurring inhaling by mistake, keeps patient airway unobstructed and provides reliable means for Patients with Mechanical Ventilation oxygen supply.

Tracheal intubation is generally under laryngoscope or soft bronchoscope guide clinically, by trachea cannula conduit moulding for tube core by glottis, puts into trachea.

Endotracheal intubation to carry out by means of under laryngoscope or soft bronchoscope views clinically at present. The common laryngoscope visual field is less, and difficult airway patient epiglottis sometimes all cannot be seen, more cannot accomplish one-time insertion success rate in the short time, repeatedly intubates and usually brings more complication even to threaten the life security of patient to patient. Although visible laryngoscope overcomes the shortcoming of common laryngoscope, but in, oral cavity very little for mouth opening or bottleneck throat anatomical structure severely subnormal, serious bones of the body breast adhesion, mandibular bone multiple fracture patient also helpless. Soft bronchoscope auxiliary intubation often needs two people's cooperations just can complete, and bronchoscope operating process is complex, time-consuming, is not easily grasped by unskilled doctor.

Summary of the invention

In view of this, the technical problem to be solved is that the common laryngoscope visual field is less, and difficult airway patient epiglottis sometimes all cannot be seen.

In order to solve above-mentioned technical problem, the invention discloses a kind of visualization tracheal intubation and lead core, including:

Leading core, inside is set to hollow;

Photographic head, leads the front end of core described in being placed in;
