Abstract

The invention relates to a foreign matter-taking out bag under an endoscope. The bag comprises an accommodating bag, direction control wires and a winding plate, wherein the accommodating bag comprises a main body, an accommodating bag tail part and a convex observing window; an accommodating outer opening is formed at the part, close to the containing bag tail, on the main body; the number of the direction control wires is two; the accommodating bag tail part is connected with the direction control wires; and the direction control wires are connected with the winding plate. By the bag, a metal sharp object downgoing along the alimentary canal and other big-volume objects which cannot be taken out by the traditional endoscope can be taken out; therefore, the bag has very strong clinical application value and popularization value. For example, a metal barb foreign matter arranged in the foreign matter-taking out bag can prevent the gastroesophageal pharyngeal mouth cavity mucosa from being damaged when the foreign matter is dragged out. The winding plate and the direction control wires of the invention can control the motion direction of the foreign matter-taking out bag, so that the operation is convenient to control and is convenient. The convex observing window of the invention can ensure that the gastroscope visual field is not affected and the operation is not limited.

Description

【Technical field】 [0001] The invention relates to a bag for taking out foreign matter, in particular to a bag for taking out foreign matter under an endoscope. 【Background technique】 [0002] Gastrointestinal foreign bodies refer to the retention of non-self-inherent substances in the upper gastrointestinal tract caused by various reasons. Small and smooth foreign bodies have little effect on the body and can be eliminated by themselves. Larger and sharp foreign bodies will cause certain damage to the mucous membrane of the digestive tract, and severe cases can lead to perforation of the digestive tract. Before endoscopic examination and treatment, foreign bodies were mainly obtained by surgical thoracotomy or laparotomy. Endoscopic removal of foreign bodies has the advantages of simple method, few complications, and high success rate. At present, most foreign bodies can be removed through endoscopy, which reduces the pain and medical expenses of patients. However, in the...
