This invention provides a digital neurosurgical microscope that, through a gas delivery mechanism and a spiral flow channel, generates a spiral airflow into the second extension tube. This effectively removes dust from the optical path and dissipates heat from the light source at the top of the inner wall of the second extension tube. After the spiral airflow is discharged, the gas discharged from several exhaust holes at the bottom of the lens mount forms an airflow barrier, preventing surrounding dust, debris, and other contaminants from contacting the lens surface, thereby reducing the possibility of lens contamination and ensuring image clarity. Furthermore, the spiral airflow, heated by the light source, reaches a temperature higher than room temperature, forming a warm airflow layer on the lens surface. When the ambient humidity is high, this reduces the chance of the lens directly contacting cold air, effectively preventing lens condensation.
