Anterior rhinoscope with opener function

Abstract

The invention relates to the technical field of medical instruments, in particular to an anterior rhinoscope with an opener function. The anterior rhinoscope comprises a mouthpiece, a supporting rod and a synchronization assembly, wherein angle blocks are symmetrically fixed to the left end and the right end of a ventilation pipe of the mouthpiece, the tail ends of rod arms at the two ends of a U-shaped rod are rotationally connected to the angle blocks at the two ends of the ventilation pipe respectively, and a pair of sliding installation bases is arranged on a rod body in the middle of the U-shaped rod; each sliding installation base comprises a sliding block connected to a rod body in the middle of the U-shaped rod in a sliding mode and a hinged support fixed to the side wall of the front end of the sliding block, a first screw groove is formed in a lug table at one end of the hinged support, a limiting shaft coaxial with the first screw groove is fixed to the inner side wall of a lug table at the other end of the hinged support, and strip-shaped guide grooves which are matched with the limiting shafts and penetrate through the rod body of the supporting rod are formed in the side wall of the supporting rod; the synchronous assembly comprises a base rod, a double-shaft piece, a connecting rod, a connecting piece and a screw rod. The anterior rhinoscope can effectively solve the problems that an anterior rhinoscope in the prior art is poor in expansion stability, can only expand one nostril at a time, is inconvenient to use and poor in safety.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a front nose mirror with the function of a spreader. Background technique [0002] Anterior rhinoscopy is a commonly used examination method by otolaryngology outpatients. It is to use something like pliers to prop up the nostrils, so that the situation inside the nasal cavity can be seen very clearly.
