Esophageal stent fixing device and using method thereof

Abstract

The invention relates to an esophageal stent fixing device and a using method thereof. The esophageal stent fixing device comprises a fixed mount, a take-up device and a force measuring box, wherein the fixed mount comprises a nose bridge frame and ear hanging frames arranged on the two sides of the nose bridge frame, the take-up device is arranged on the nose bridge frame, the take-up device is connected with the force measuring box through a connecting wire, the force measuring box comprises a box body and a sliding block arranged in the box body, a spring is arranged between one side of thesliding block and the inner wall of the box body, a pull rod is arranged on the other side of the sliding block, a wire binding ring extending out of the box body is arranged at the end of the pull rod, a traction wire is wound on the wire binding ring, and the box body is made of transparent plastic, and scales are arranged on the outer wall of the box body. The esophageal stent fixing device isused for fixing an esophageal stent, accurate fixing of the stent can be achieved, whether the stent moves or not can be conveniently and accurately judged during postoperative nursing, and the treatment effect is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to an esophageal stent fixing device and a usage method thereof. Background technique: [0002] Esophageal stents are widely used in the clinical treatment of esophageal stenosis, esophageal tracheal fistula and other diseases caused by various reasons. For these diseases, a covered esophageal stent can be placed in the esophagus and removed when the stenosis is relieved, the fistula is healed or the next step is taken. Stents for therapeutic purposes. Since the stent coating cannot be closely attached to the esophageal wall, it is prone to shift or even fall into the gastric cavity and intestinal cavity, thereby affecting the treatment effect and even causing serious complications such as intestinal obstruction and intestinal perforation. The wires are pulled orally or nasally to prevent the stent from dislodging or falling out. Clinically, the extracorporeal recovery li...
