Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a foreign body extractor for ENT (ear, nose and throat). Background Art

[0002] The types of foreign bodies in the ear, nose and throat are generally divided into the following four categories: biological, food, foreign object and iatrogenic. Clinically, there are often cases where foreign bodies in the ear, nose and throat are difficult to remove. Since the ear, throat and nose are all small cavities, when removing foreign bodies from the ear, pharynx and nasal cavity, since the foreign body in the nasal cavity may be round or smooth, ordinary forceps cannot be used to clamp it. Ordinary forceps may cause the object to be pushed deeper into the nasal cavity, so it will fall into the throat and trachea, and there is a risk of dyspnea and asphyxia. Therefore, it is necessary to use a foreign body hook to hook the foreign body to improve the stability of foreign body removal.

[0003] The existing foreign body hook for ENT has the following main deficiencies. For example, when using the foreign body hook to hook a round or smooth foreign body deep in the nasal cavity, it is necessary to slowly move the foreign body hook to prevent damage to the nasal cavity. When the foreign body is hooked to a position close to the nostril, the foreign body can be quickly removed by the foreign body forceps to avoid the foreign body slipping back into the nasal cavity. However, using the foreign body forceps to clamp the foreign body requires removing the foreign body hook from the nasal cavity and then inserting the foreign body forceps into the nasal cavity, which will affect the progress of the operation, and the large movement amplitude of using the foreign body forceps will cause damage to the nasal mucosa. Content of the Utility Model
