Abstract

The invention discloses a percutaneous-puncture stomach-wall and intestinal-wall fixing device. The percutaneous-puncture stomach-wall and intestinal-wall fixing device comprises an inner fixing ring, an outer fixing wire and an outer fixing box. The inner fixing ring and the outer fixing wire are made from a nickel-titanium alloy wire in a shaped mode, and one end of the nickel-titanium alloy wire is spiraled inwards, and the nickel-titanium alloy wire is normally kept in a hopper shape to form the inner fixing ring; the other end of the nickel-titanium alloy wire linearly extends from the center of the inner fixing ring in the opening direction of the inner fixing ring to form the outer fixing wire; the outer fixing wire is wound around and fixed on the outer fixing box, and the fixing box is provided with a bandage for being fixed to the human body. According to fixing device, the stomach wall or the intestinal wall and the abdominal wall can be conveniently, rapidly and firmly fixed, the operating efficiency of an operation is improved, operation wounds are reduced, and complications are reduced.
