Abstract

A paranasal sinus endoscope according to an embodiment of the present invention comprises a main body provided with a plurality of operation units; an insertion part which extends from the front end of the main body, is inserted into the paranasal sinus through the nasal cavity, and is provided with at least one working channel; and an applicator head provided to the main body and capable of loading a plurality of applicators that are selectively accessible through the working channel.

Description

technical field [0001] The present invention relates to endoscopes, and more particularly to endoscopes that can be used to treat sinusitis. Background technique [0002] Chronic sinusitis is a common disease affecting 8.6% of the Korean population. Functional endoscopic sinus surgery (Functional endoscopic sinus surgery) for the surgical treatment of chronic sinusitis requires general anesthesia in most cases. Although it is rare, serious complications such as intraorbital complications and cerebral hemorrhage may be induced complication. [0003] In addition, the surrounding tissue is damaged during the operation, so there will be postoperative pain and the recovery speed will be slow. To ameliorate these problems, a surgical approach was developed in which a small balloon catheter is inserted into the nasal cavity to minimize damage to surrounding structures and open the natural sinus ostia, which has the advantage of requiring only local anesthesia, recovery time Shor...
