Problems solved by technology

[0002] In the current technology, when a person's nasal cavity or paranasal sinuses suffer from various diseases, doctors often use a nasal cavity expander to open the patient's nasal cavity for observation or surgery. This nasal cavity expander is fixed by two crossed It is composed of movable struts together. The two movable struts are provided with a handle on one side of the fixed point, and an expansion end that can extend into the nasal vestibule on the other side. When in use, the expansion end is extended into the nasal cavity of the patient. Hold the handle to control the opening and closing degree of the expansion end. The existing nasal cavity expander not only has a large structure, but also requires one hand to operate, which brings inconvenience to the doctor during the operation. In addition, if the nasal cavity expander is reused, it is easy to cause crossover. Infection, repeated disinfection also increases the work intensity of medical staff
