Abstract

The invention relates to a capsule gastroscope taking-out device, and belongs to the field of medical instruments. The capsule gastroscope taking-out device 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 mode and axially slides in the outer sheath assembly under the action of the operation assembly; the mandrel assembly comprises a mandrel body, a gripper and an elastic sleeve piece; the outer sheath assembly comprises an outer sheath body, a cross-shaped opening and a magnetic piece; 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 abutting of the magnetic piece;and the mandrel body continues to slide towards the far end in the outer sheath body, at the moment, the gripper continues to extend out towards the far end, and due to the fact that a cantilever ofthe gripper is long, the far end of the gripper forms a closing opening under the action of the elastic sleeve piece. According to the capsule gastroscope taking-out device, a capsule gastroscope magnetic ball is attracted through the magnetic piece so that the capsule gastroscope magnetic ball can be rapidly aligned with a capsule gastroscope to be taken out, then the gripper extends out and completely wraps the capsule gastroscope to form the closing opening, and as a result, the capsule gastroscope can be rapidly 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...
