A device for removing foreign body from digestive tract

Abstract

The invention relates to the field of auxiliary medical technology, and discloses an efficient, quick and safe device for removing foreign bodies in the digestive tract under endoscopy, which includes a plurality of struts hinged along the circumferential surface at the head end of the protruding tube. There is a sliding sleeve, and the outer peripheral surface of the sliding sleeve is hinged with a number of struts equal to the number of struts. The top of the struts is hinged between the two ends of the struts. A control rod is longitudinally provided in the protruding pipe, and the control rod is connected to a sliding sleeve through a fixed block passing through the through groove A, and the outer surface of the strut is jointly connected to the inner surface of the tapered net bag, and the cylindrical The tapered net bag extends the tube and pushes out the claws above the foreign matter, which can push the foreign matter into the lower net bag, and the control wire on the contraction part of the net bag tightens and wraps the foreign matter. The invention solves the problems of low success rate, long time consumption and easy damage to the digestive tract when taking out the foreign body under the clinical endoscope.

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...
