[0001] The invention relates to the field of medical devices, in particular to a sucker-shaped airway foreign body extractor. Background technique

[0002] At present, there are two main methods for taking out foreign bodies in the trachea and bronchus: one is to rely on bronchoscope biopsy forceps, rat bite forceps, and crocodile forceps to clamp foreign bodies and take them out.

It is necessary to...
