Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an expandable foreign body forceps. Background Art

[0002] Foreign bodies in the esophagus often include sharp objects such as fish bones, animal bones, wire, and date pits. These can puncture the esophageal mucosa and become lodged in the esophagus. Foreign bodies can cause perforation or even puncture the aorta. If both ends of the foreign body become lodged in the esophagus during removal, it can be extremely difficult for the doctor, potentially leading to difficulty in removal and displacement.

[0003] Insert the foreign body forceps into the location of the foreign body in the esophageal cavity, use the foreign body forceps to free one end of the foreign body from the esophageal wall, and then use the foreign body forceps to clamp the free foreign body so as to perform the foreign body removal operation.

[0004] Since repeated attempts are required to free the foreign body, the foreign body may be pushed into deeper tissues, thereby reducing the effectiveness of the foreign body forceps. Moreover, the freed foreign body will slide freely in the esophageal cavity, making it more inconvenient to operate the foreign body forceps during the removal process. There is an urgent need to design an expandable foreign body forceps to solve the above problems. Utility Model Content
