Handheld portable high-definition electronic nasopharyngeal laryngoscope

Abstract

The invention discloses a handheld portable high-definition electronic nasopharyngeal laryngoscope, and relates to the technical field of medical equipment. The nasopharyngeal laryngoscope comprises an endoscope tube, wherein the endoscope tube comprises two holding shells, the two holding shells are fixedly connected, one end of each holding shell is provided with a bending assembly, the two bending assemblies are fixedly connected, and transmission assemblies are arranged in the two holding shells; the bending assembly comprises a second guide block, a guide shell is fixed to an outer wall of one end of the bending assembly, the guide shell is located between two rotating seats and rotationally connected with the two rotating seats through rotating shafts, a second fixing block is fixedto an inner wall of the bending assembly, and the second guide block is clamped to the other end of the bending assembly. According to the nasopharyngeal laryngoscope, through arrangement of the bending assembly and the transmission assembly, the endoscope tube can quickly and conveniently enter the throat or a part below the throat in a mechanical mode, and a problem that an existing nasopharyngeal laryngoscope tube cannot easily enter the throat or a part below the throat of a patient is solved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a hand-held portable high-definition electronic rhinolaryngoscope. Background technique [0002] Electronic nasopharyngoscope is a medical device for examining the nasopharynx, throat and larynx, and can perform biopsy, surgical treatment of vocal cord nodules or small vocal cord polyps, and removal of foreign bodies in the pharynx. It is a kind of optical fiber equipment. When performing a detailed examination of the larynx, the lesion can be magnified thousands of times through the imaging technology of the microscope, and the doctor can use the enlarged vocal cord cyst and other pathological tissues to treat the vocal cord polyps, vocal cord nodules and other diseases with its own surgical forceps. Outpatient surgical treatment of vocal cord lesions requires short operating time, but when the existing electronic rhino-laryngoscope is used for laryngeal examination, m...
