Description

Technical Field

[0001] The present invention relates to the field of medical care, and more particularly to an intelligent esophageal fishbone extractor based on machine vision technology. Background Art

[0002] Fish, because of its rich nutrition and delicious taste, is a very common ingredient in people's daily diet and banquet guests. But when tasting fish, if you are not careful, it is easy to get a fish bone stuck in your throat. According to medical statistics, there is an 80% chance that fish bones are stuck in the front end of the esophagus, such as the lower end of the tonsils and the root of the tongue. In this case, the throat will hurt when swallowing saliva. If the fish bones are stuck in this position and are not removed in time, in addition to causing difficulty in swallowing, there are also reports of suffocation and death due to throat edema. In addition, 20% of larger fish bones will get stuck in the esophagus, which is more dangerous than getting stuck in the throat. If the patient who is stuck does not pay attention at the moment, it may cause gastrointestinal inflammation, and even the fish bones may directly poke the aorta, which is also fatal in severe cases. When encountering a fish bone stuck in the throat, most people will use some folk methods, such as drinking vinegar, swallowing rice balls, steamed buns, vegetables, drinking a lot of water, etc., but these are all wrong practices, because blindly trying to swallow the fish bone is likely to cause the fish bone to be inserted deeper, and at the same time it will damage the throat and cause infection, suppuration, inflammation and swelling. In addition, drinking vinegar cannot soften the fish bone as people expect, and swallowing a large amount of vinegar in a short time may also burn the throat and esophagus. Therefore, rather than "swallowing" the fish bone, "getting" it out is the right way. At present, the safest and most reliable way to remove the fish bone is to go to the hospital as soon as possible to seek help from a doctor. However, due to the limitations of local medical conditions, not everyone who is stuck with a fish bone can get timely treatment. Summary of the invention

[0003] In order to effectively solve the above problems, the present invention proposes an intelligent esophageal fishbone extractor based on machine vision technology. Using this extractor, fish bones can be removed safely and effectively to avoid further damage.
