Description

Indirect laryngoscope with light source

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to an indirect laryngoscope of taking light source.

Background

The throat is the portal of the respiratory and digestive tracts, and various pathogens easily cause infection through breathing and eating; trauma can also be caused by careless eating or external violence; diseases of blood, nerve and other systems and some infectious diseases can also find abnormality in the throat; in addition, throat tumor not only endangers the life of the patient, but also causes irreversible functional disorders such as dysphagia and aphonia of the patient, and seriously affects the life quality of the patient. Therefore, diagnosis of benign and malignant diseases of the throat is required to be performed by an intuitive and easy-to-use examination method.

Because the larynx is deep and complicated in physiological structure, and cannot be directly peened, a doctor usually needs to use a laryngoscope to perform the laryngeal examination, and an indirect laryngoscope is the most common and the most basic laryngeal examination device. An indirect laryngoscope is a circular flat mirror with a handle, the intersection angle of the mirror surface and the handle is usually about 120 degrees, the diameters of the mirror surfaces are different, and the mirror surfaces can be selected according to the pharyngeal cavity condition of a detected person. Although endoscopic systems are currently available for direct close-up viewing of the region deep in the throat. However, endoscopes, as an invasive procedure, have certain requirements on medical workers, disinfection, and patient compliance. Currently, the traditional Chinese medicine preparation cannot be used for the first visit of outpatients and should not be used for the first visit of outpatients. The throat disease diagnosis and treatment process is shown in figure 1, so that the use of an indirect laryngoscope cannot be replaced in clinical work; the indirect laryngoscope is a medical instrument which must be used in the diagnosis and treatment of the diseases.

However, the prior indirect laryngoscope is simpler due to the working principle, but has inherent defects in the using process. In clinical practice, laryngoscopes are often used in conjunction with tongue depressors and must rely on a light source and wear a frontal mirror or headlight to enable examination of the patient's throat. Especially, when the diagnosis room does not have a medical special light source or a doctor goes out a doctor, the medical clinical diagnosis and treatment effect can be directly influenced.
