Rhinoscope for human nasal surgery and using method

Abstract

The invention discloses a rhinoscope for human nasal surgery and a using method. The rhinoscope comprises a mirror barrel, a mirror image tube, a handle, an outer mirror tube, light-guide fibers, an inner mirror tube, a mirror surface, a cleaning assembly, an expansion assembly, a lens, an air inlet balloon, a pump, an operation box, a water storage chamber, a sewage discharging chamber and an emptying machine. The mirror barrel is disposed at one end of the mirror image tube. By arranging the cleaning assembly, water in the water storage chamber can be pumped and drained through operation ofthe pump; a rotating shaft is arranged in the water storage chamber, a plurality of flow guide plates are arranged around the circumferential surface of the rotating shaft, during water inflow, clearwater is guided in from one side of a rotating frame, under cooperation of the flow guide plates, the clear water can be guided to flush the mirror surface, cleanliness of the mirror surface is guaranteed, and blood water can be flushed away; and after flushing, the sewage discharging chamber is emptied to form a low-pressure space inside, under stirring cooperation of the flow guide plates, bloodwater obtained after flushing can be pumped away through a liquid discharge pipe, it is guaranteed that the interior of a nasal cavity is clean, and the conditions of a wound in the nasal cavity canbe better observed.

Description

Technical field[0001]The invention relates to the technical field of medical equipment, in particular to a nasal endoscope for human nasal cavity surgery and a method of use.Background technique[0002]Nasal endoscope is an otolaryngology equipment that can perform detailed inspections of the nasal cavity. It generally refers to a rigid tubescope, which has an angle ranging from 0 to 90 degrees. It has good lighting and itself. It is relatively thin, with a diameter of only 2.7-4.0mm, but the nasal endoscope is sometimes referred to as a tubescope. The nasal endoscope can easily inspect the internal structure of the nasal cavity, nasopharynx and even the sinuses through the narrow nasal cavity and nasal passages. It is an important means for diagnosing sinusitis and nasal polyps. It can also be used with supporting surgical instruments. Sinusitis and nasal polyps are treated carefully, so that the operation can reach the area that cannot be reached by traditional surgery;[0003]When th...
