Alimentary canal foreign matter extractor for gastroenterology

Technical Field

The invention belongs to the technical field of foreign body extractors, and particularly relates to a digestive tract foreign body extractor for a digestive system department.

Background

The digestive tract is a long muscular tube which extends from the oral cavity to the pharynx, esophagus, stomach, small intestine, large intestine and finally anal canal, and comprises the oral cavity, the pharynx, the esophagus, the stomach, the small intestine (duodenum, jejunum and ileum), the large intestine (cecum, appendix, colon and rectum), the anal canal and the like. The digestive glands include small digestive glands and large digestive glands. The small digestive gland is located in the wall of each part of the digestive tract, and the large digestive gland has three pairs of salivary glands (parotid gland, submandibular gland and sublingual gland), liver and pancreas, which are all drained into the digestive tract by means of ducts.

For example, application No.: the invention relates to the technical field of medical instruments, in particular to a foreign matter taking-out device for a digestive system department. According to the invention, the lower end of the intubation tube is fixedly provided with the air bag protective sleeve, the air bag protective sleeve is trapezoidal and hollow inside, when the intubation tube is inserted into a patient, the foreign matter taking-out structure arranged at the lower end of the intubation tube is wrapped by the air bag protective sleeve, the intestines and stomach of the patient are prevented from being scratched in the inserting process, the protective effect is achieved, meanwhile, when the foreign matter is grabbed, gas in the inflator is injected into the air bag protective sleeve through the inflating pipe by pushing the push rod, so that the air bag protective sleeve is expanded, the body tissue of the foreign matter part is slightly propped open, the specific position of the foreign matter is convenient to observe, and meanwhile, the clamp is convenient.
