[0002] In the hospital, we often see many patients accidentally getting fish bones, bones or other foreign objects stuck in their bodies, especially children, who are prone to swallowing various toy parts and other things. This requires endoscopists to help patients remove them in time. Although there are many kinds of foreign body forceps and foreign body nets now, the overall feeling after using them is that the foreign bodies are stained with mucus, which is very slippery and difficult to grasp. They are easy to fall off after being grasped. Before the foreign bodies are completely removed, the equipment used has already degenerated and cannot be used. The process of removing sharp foreign bodies such as fish bones is also easy to scratch the esophagus, and the use of various foreign body removal instruments also has high requirements for operators. Therefore, there is an urgent need for a new endoscopic foreign body removal device to solve the above problems. Summary of the invention
