The invention discloses a trachea
cannula guide wire, which comprises a
handle, a
metal tube matched with a trachea cannula and an auxiliary device convenient for a user to see a trachea orifice clearly, and the
metal tube comprises a first linear part connected with the
handle and a fine adjustment part capable of extending into the
oral cavity of a patient along with the trachea cannula. The shape of the fine adjustment part is matched with the path from the
oral cavity to the trachea orifice. According to the trachea
cannula guide wire, the
metal tube is used for replacing a traditional guide wire, due to the fact that the
hardness of the metal tube is large, the guide wire body is not prone to deformation under the action of external force, and shaping is more stable; and due to the metal characteristic of the metal tube, the fine adjustment part can perform small-angle fine adjustment shaping to adapt to different patients, so that the
anatomical structures of the patients are met to the greatest extent, and
intubation operation is facilitated. Moreover, a plastic sheath on the surface of the original guide wire is removed, the metal tube can be directly disinfected in an
alcohol wiping manner during use, the operation is simple and convenient, and the possibility that the trachea cannula is polluted is reduced.
