Description

Can change multi-functional nasal endoscope of peeping angle

Technical Field

The utility model relates to the technical field of medical equipment, especially a can change multi-functional nasal endoscope of peeping angle.

Background

The nasal endoscope is also called nasal endoscope, and is one of the most commonly used devices in the otolaryngological department. Most nasal, sinus and nasopharyngeal diseases, and even cranial base diseases, now require intranasal endoscopy for definitive diagnosis. Most minimally invasive nasal procedures also require that the procedure be performed under intra-nasal endoscopic monitoring. During a nasal endoscope operation, one hand is generally used for holding the nasal endoscope, and the other hand is used for holding an operation instrument.

Currently, the nasal endoscope used clinically is a rigid nasal endoscope, the visual field range is fixed, and therefore, when structures such as maxillary sinus, frontal sinus and sphenoid sinus crypt are observed, the observation of the operative region is often guaranteed by replacing an angle mirror (commonly used mirrors with 30 degrees, 45 degrees and 70 degrees). However, since the rigid nasal endoscopes are all straight rod-shaped structures, even if an angle mirror is adopted, an observation blind area exists, so that lesions in the blind area cannot be comprehensively observed, evaluated and processed in an operation. The flexible endoscopes such as the fiber nasopharyngoscope and the electronic nasopharyngoscope can change the lens angle at the front end, so that the pathological changes in the hard nasopharyngoscope examination blind area can be observed conveniently, but due to the characteristics of the flexible structure, a doctor can hold the endoscope with both hands when using the endoscope, and cannot perform operation at the same time.
