Technical Field
The invention relates to the technical field of medical equipment, in particular to a portable ear-nose-throat endoscope with a suction system.
Background
The endoscope is widely applied in the medical field in the 60 s of the 20 th century, the image quality of the endoscope is greatly improved by the cylindrical lens, the glass fiber with excellent light guiding property invented by Basil Hirschowitz creates the first practical endoscope for medical examination, and the endoscope with examination and operation functions does not appear until the 1970 s. Due to the complex anatomy and narrow channel of the otolaryngological department, the endoscope system is applied later, but the change of diagnosis and treatment modes caused by the endoscope system is subversive. At present, endoscopy in guidelines of otorhinolaryngology department for common emergency treatment diseases (such as ear diseases, acute and chronic suppurative otitis media, tinnitus, sudden deafness and the like, nasal diseases, acute and chronic rhinosinusitis, nasal septum deflection, epistaxis and the like, throat diseases, acute and chronic pharyngitis, tonsillitis, gland hypertrophy, vocal cord polyp, vocal cord nodules, snoring, foreign bodies in pharynx and the like) becomes one of indispensable items in definite diagnosis and even surgical treatment.
The ear, nose and throat parts are communicated with the external environment, mucous membranes and secretory glands are abundant, most diseases have secretion to interfere with image quality when the endoscope is used, and local flushing is possibly needed during examination or treatment, so that a suction device is often needed to assist in clearing the secretion and sucking flushing liquid when the endoscope is used. For example, when a foreign body at the pharyngeal portion, which is the most common disease in the emergency treatment of otolaryngological department, is treated, the requirement for the image quality is high when a small foreign body which is not easy to be found, such as a fishbone, is searched and taken out under the direct view of an endoscope, but the current suction device and the endoscope system are not integrated into a whole, and the foreign body taking operation cannot be completed by a single person. In addition, the suction device and the endoscope system are complex in composition, large in size and inconvenient to carry, and are inconvenient for patients who have difficulty in moving to make a diagnosis and treatment.
