Seeing that thing lying on the velvet inside the box, it's well protected. The thin metal stick has a small mirror attached, somewhat like a dental mirror but longer. So it's definitely not a dental mirror, it's indeed a laryngoscope.
But—
"An antique." Zhang Huayao opened his mouth to criticize.
What kind of laryngoscope is an antique laryngoscope? It's an indirect laryngoscope, pretty much one of the earliest laryngoscope structures invented. The thin, long metal rod allows the attached mirror to be inserted deep into the patient's oral cavity, letting doctors observe the condition of the patient's throat through the reflection. At this time, the situation seen through the mirror is opposite to the actual internal structure of the body, hence it's called an indirect laryngoscope.
