Problems solved by technology

A kind of " flat polyp operation snare " disclosed as Chinese patent CN201248743Y is exactly this kind of structure, although this snare can effectively avoid the slippage phenomenon of the snare, and simple in structure, easy to operate, but still exists the following deficiencies: After the polypectomy with the snare, the polyp needs to be removed for pathological analysis. Since the double-channel endoscope is expensive, clinically more single-channel endoscopes are used, so it is necessary to insert the foreign body forceps or net bag to remove the polyp after withdrawing the snare. It is troublesome to take out, time-consuming and labor-intensive, and due to the peristalsis of the stomach, it is not easy to find the polyp after activity, which makes it troublesome to take out the polyp
