Description

Electromagnetic type endoscope foreign matter taking device

Technical Field

The utility model relates to a get foreign matter auxiliary assembly field, specifically an electromagnetic type foreign matter device is got to scope.

Background

Clinically, exogenous foreign matters are swallowed into the stomach, and the swallowed foreign matters are blocked and retained in the esophagus. Most foreign bodies in the stomach can be discharged from the stomach cavity and the intestines to the outside, which rarely causes discomfort or only causes slight symptoms of dull pain, fullness, nausea and the like of the upper abdomen. When the foreign body is large, it can be embedded and plugged in the pylorus, the duodenal jejunal flexure, the ileocecal valve and other parts. The incidence of foreign matters in children is increasing day by day, and the variety of the foreign matters is more and more seen in children toys, coins and ornaments. After the children swallow the foreign body, the following problems often exist: 1. the foreign body is stuck in one of three narrow parts of the esophagus and does not enter the stomach; 2. foreign bodies are in the stomach and do not enter the duodenum through the antrum; 3. foreign bodies enter the intestinal tract through the duodenum. The device mainly takes out foreign matters in the second situation. Foreign bodies in the stomach, due to low digestion ability and slow peristalsis of children, are easy to wrap with food, and the difficulty of taking out is increased, and the methods for discharging the foreign bodies in the stomach at present are as follows: 1. natural elimination method, 2, endoscopic extraction method, 3, operative extraction method, natural elimination method, more than 80% of foreign bodies in stomach can be eliminated naturally. The average time for the foreign matter to be naturally discharged is about 5 days. Can be administered with liquid paraffin or Chinese medicinal materials to help natural discharge. But a few sharp foreign matters (toothpicks, nails, broken glass and the like) and toxic articles (batteries containing strong alkali and the like) are easy to damage the mucous membrane of the alimentary canal to cause gastric perforation, and the foreign matters are to be actively treated and can be taken out by endoscope or operation when necessary. Endoscopic extraction is a main means for the treatment of foreign body in stomach, and can remove the surgical pain. The surgical extraction method is to extract the foreign body timely when the foreign body is large and stays in the stomach, or the gastroscope treatment fails, or the sharp foreign body and the toxic foreign body enter the small intestine to cause harm to the organism. Under the assistance of endoscope, at first through X line inspection, confirm whether there is the metallic foreign body and inlay the foreign matter that has the metal part, again through scope cooperation biopsy forceps take out the foreign body, but child's digestion ability is low, when using biopsy forceps to get the foreign body, press from both sides the difficulty to the metallic foreign body, and biopsy forceps's dynamics is not very well mastered yet, can drop at the in-process of taking out, can not once only take out, especially when meetting sharp-pointed metallic foreign body, the biopsy forceps holder is got inaccurately, can cause the injury to patient's health. Therefore, an electromagnetic endoscope foreign body taking device is needed to solve the problems.
