[0002] Otolaryngology, also known as otolaryngology-head and neck surgery, mainly treats diseases of the ears, nose, throat, head and neck and related diseases of the above parts. Currently, it has also carried out minimally invasive surgery on the lateral skull base, transnasal intracranial tumor resection, transnasal petrous apex lesion surgery, optic nerve decompression, cerebrospinal fluid rhinorrhea and otorrhea repair, etc. When people eat, foreign objects may get stuck in their throats, such as fish bones, etc. Children, especially, are curious about things and are prone to swallowing date pits, melon seed peels or toys. The existing method of removing foreign objects is mostly to use throat foreign body forceps, which are inserted into the patient's throat to remove the foreign body.

[0003] When a foreign body is stuck in the throat, the direction in which the foreign body is stuck in the throat of each patient is different, including horizontal, vertical or diagonal directions. When medical staff use throat foreign body forceps to clamp the foreign body, they need to adjust the angle of the throat foreign body forceps by hand so that the throat foreign body forceps can smoothly remove the foreign body. As a result, medical staff need to raise their arms for a long time and maintain the required angle during the process of clamping the foreign body, which can easily cause soreness and fatigue in the arms of medical staff, making it easy for mistakes to occur when clamping the foreign body, causing harm to patients.
