Technical Field

The invention relates to the field of medical appliances, in particular to an unlocking extractor for a metal clip of a digestive tract.

background

At present, foreign body forceps and the like are commonly used at home and abroad, and a metal clip clamped in tissues is pulled out under a digestive endoscope. When in operation, the metal clip is used for preventing bleeding perforation and needs to be deeply and tightly clipped, but the wound surface is healed after the operation, the metal clip is not easy to fall off and is difficult to pull out, and new wounds can be caused by violent pulling out. Although the foreign body forceps are mastered in skill, a part of the metal clip can be pulled out, but the foreign body forceps are not special instruments after all and are time-consuming and labor-consuming. The key reasons are: the metal clip is easily pulled out, two tooth feet of the metal clip are separated firstly, or one tooth foot of the metal clip is pulled out firstly.

But in fact, after the metal clip is closed, the gap between the two pins is very small, each of the two forceps teeth of the foreign body forceps is very thick, so that the foreign body forceps cannot drill between the two pins of the metal clip and separate the pins, and one pin of the metal clip is difficult to clamp and pull out, so that the metal clip can only be pulled out from the tissue in a living and growing way, some wires cannot be pulled out, some wires can be pulled out with great effort, some wires are pulled out to stop bleeding by using the metal clip, and some parts with weak tissues are often punctured by pulling out the metal clip.

therefore, how to provide a flexible and safe digestive tract metal clip unlocking puller is a problem to be solved urgently by those skilled in the art.
