Abstract

The invention relates to a capsule gastroscope extractor, and belongs to the field of medical instruments. The extractor comprises an outer sheath assembly, a mandrel assembly and an operation assembly, wherein the mandrel assembly is arranged in the outer sheath assembly in a penetrating manner and axially slides in the outer sheath assembly under the action of the operation assembly; the mandrelassembly comprises a mandrel body, a gripper and an elastic suite; the outer sheath assembly comprises an outer sheath body, a cross-shaped opening and a magnetic part; when the mandrel body slides towards the far end in the outer sheath body, the gripper extends out of the cross-shaped opening and is propped open under the propping action of the magnetic part; the mandrel body continues to slidetowards the far end in the outer sheath body, and at the moment, the gripper continues to stretch out towards the far end; and due to the fact that a cantilever of the gripper is relatively long, thefar end of the gripper forms a closing opening under the action of the elastic suite. According to the invention, the magnetic part attracts a capsule gastroscope magnetic ball to be rapidly alignedwith a capsule gastroscope to be taken out, then the gripper stretches out and forms the closing opening after completely wrapping the capsule gastroscope, and therefore the capsule gastroscope can berapidly taken out.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a capsule gastroscope take-out device. Background technique [0002] With the development of medical technology, capsule gastroscopy has become the choice of more and more patients, truly realizing the non-invasive, painless and anesthesia-free gastroscopy. However, some patients cannot expel normally when there are structural abnormalities in the digestive tract, such as digestive tract obstruction, large ulcers, or diverticulum that protrudes from the intestinal wall. At this time, it is necessary to use a gastroscope or a colonoscope to take the capsule endoscope out of the body with instruments. [0003] At present, there is no special device for capsule gastroscopy removal. The common practice is to use a snare to extend into the endoscope channel to trap the capsule gastroscope, and withdraw it together with the endoscope. Since the surface of the capsule gastroscope is smo...
