Description
Technical Field
The invention relates to the field of medical appliances, in particular to a video laryngoscope capable of adjusting an angle of a lens through motor driving.
Background
The video laryngoscope is a novel video intubation system, a high-definition anti-fog camera is arranged at the front end of a lens of the video intubation system, two light emitting diodes provide light rays and contrast, and an image is transmitted and amplified to a liquid crystal display through an optical cable.
The video laryngoscope is mainly suitable for the patients with limited head and neck movement (such as cervical vertebra injury and dislocation of the pivot joint), oral and maxillofacial trauma, limited opening after trauma or burn (but opening degree is more than 18 mm) and difficult airways with higher glottic position, which need operation treatment or emergency rescue, the rapid transnasal tracheal intubation is guided, the laryngoscope can observe the throat structure through the liquid crystal display, and the whole process of catheterization of the glottic is improved, the teaching efficiency is improved, the laryngeal exposure is easier, the laryngeal exposure grading can be improved, and the laryngeal exposure grading achieved can be reduced by I-II level than that of the direct laryngoscope when the video laryngoscope is applied to the patient with cervical scar adhesion for tracheal intubation operation. The combination of external operation of the throat can improve the appearance grading of the throat, the operation is simple and easy to learn, the damage to the trachea cannula is small, in addition, compared with a fiber optic bronchoscope, the video laryngoscope is used for the outstanding advantages of the trachea cannula market: (1) the operation technology is simple (2) has no limitation on the type of the tracheal catheter; (3) less affected by blood and secretions in the mouth and pharynx; (4) the situation (5) that the glottis is blocked generally cannot occur when the tracheal catheter is inserted adopts special anti-fog treatment materials, is not easily affected by the temperature difference between the respiratory tract and the external environment, and therefore the phenomenon that the condensation film is formed on the front end surface of the camera by expired air to reduce the definition of the exposed throat can be effectively avoided, and the use is reliable. Compared with a common laryngoscope, the design of the video laryngoscope has no exposed circuit contact point of the lighting device, thereby reducing poor contact fault. The laryngoscope lens is made of special plastic, and the camera and the optical cable are protected in a totally-enclosed way, so that the cleaning, disinfection and sterilization treatment are easier. In the production of medical instruments, a video laryngoscope which is convenient to process and can adjust the angle of a lens through motor driving does not exist at present.
