[0002] In the nasal cavity department of a hospital, patients with severe nasal congestion in children or foreign bodies in the nasal cavity caused by accidental reasons are often encountered. The foreign bodies are not firmly fixed and are not easy to remove, or they enter the pharynx and fall into the trachea, which is likely to cause inspiratory dyspnea. In severe cases, it endangers the life of the patient. The traditional treatment method is to use instruments such as forceps to remove the foreign body from the nasal cavity. However, the ends of instruments such as forceps and pliers can only clamp the foreign body, and the space in the nasal cavity is narrow. The opening angle of the forceps is limited, and it is impossible to clamp foreign bodies with a larger volume. Moreover, when clamping a foreign body blocking the nasal cavity, the forceps need to pass through both sides of the foreign body, which is likely to puncture the nasal mucosa and cause nasal bleeding. Therefore, a pair of nasal foreign body removal forceps is proposed. Content of the Utility Model
