Abstract

The invention relates to the technical field of auxiliary medical treatment, and discloses an efficient, fast and safe endoscopic gastrointestinal foreign matter taking-out device. The device comprises a plurality of supporting rods hinged to the head end of an extending pipe along the circumferential surface, wherein a sliding sleeve is arranged on the surface of the extending pipe, and supporting rods of which the quantity is equal to that of the supporting rods are hinged to the outer circumferential surface of the sliding sleeve; the top end of each supporting rod is hinged between the twoends of the corresponding supporting rods; a longitudinal through groove A is formed in the side wall of the extending pipe; a control rod is longitudinally arranged in the extending pipe; the control rod is connected to a sliding sleeve through a fixing block penetrating through the through groove A; the outer surfaces of the supporting rods are jointly connected to the inner surface of a conical net bag; the extending pipe pushes a pushing claw out above a foreign matter, the foreign matter can be pushed into the net bag below, and the control steel wire on a net bag contraction part is tightened to wrap the foreign matter. The invention solves the problems of low success rate, long time consumption and easy damage to the digestive tract when the foreign matters are taken out under a clinical endoscope at present.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical treatment, in particular to a device for taking out foreign bodies in the digestive tract. Background technique [0002] Gastrointestinal foreign bodies are one of the most common diseases in clinical emergency (especially esophageal foreign bodies). Children and the elderly are most likely to accidentally swallow foreign objects and cause incarceration. There are many kinds of foreign bodies in the digestive tract, and sharp and protruding foreign bodies such as fish bones, chicken bones, date stones, dentures, blades, nails, toothpicks, hard metal wires, etc., can cause a high rate of digestive tract perforation. Foreign objects such as small marbles, magnetic beads, and button batteries, once passed through the stomach, pose a high risk of intestinal perforation, requiring surgery. Usually, the foreign body forceps are used by the doctor to clamp out the foreign body through the dig...
