Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ear, nose and throat foreign body remover. Background Art

[0002] Otolaryngology is a surgical discipline that diagnoses and treats the ear, nose, throat and related head and neck areas. Clinically, there are often cases where foreign bodies in the ear, nose and throat cause discomfort to patients. Because the organs where the foreign bodies are located are small, they cannot be removed directly by hand, so medical staff usually need to use instruments to remove the foreign bodies.

[0003] Currently, when removing foreign bodies from the ears, nose and throat, they are mostly clamped with hand-pinched forceps. Not only is the stability poor, but the palms are prone to pain and fatigue. In particular, when clamping foreign bodies in the throat, the patient's unconscious swallowing and slight closure of the mouth can easily cause the throat to close, which not only causes the foreign body to move, but also requires the forceps to be re-pinched to clamp the foreign body, which is time-consuming and laborious, very inconvenient to operate, and has a poor use effect.
