Nickel-titanium memory alloy esophageal stent placing and recycling device used in X-ray perspective

Abstract

The invention provides a nickel-titanium memory alloy esophageal stent placing and recycling device used in X-ray perspective. The nickel-titanium memory alloy esophageal stent placing and recycling device used in X-ray perspective comprises an outer sleeve, an inner sleeve, sampling pincers and a nickel-titanium memory alloy esophageal stent, wherein the head of a jaw of the sampling pincers is inserted in the inner sleeve; the inner sleeve is inserted in the outer sleeve; a latex ring is sleeved on the outer wall of the lower end of the inner sleeve; trumpet-shaped handles are arranged at the rear end of the outer sleeve and the rear end of the inner sleeve; the upper end of the nickel-titanium memory alloy esophageal stent is sleeved on the latex ring; the lower end of the nickel-titanium memory alloy esophageal stent is sleeved at the lower end of the inner sleeve; and a metalized annular tightening line is arranged at one end of the esophageal stent. The nickel-titanium memory alloy esophageal stent placing and recycling device used in X-ray perspective has the advantages that the nickel-titanium memory alloy esophageal stent placing and recycling device is simple in structure, can be placed or recycled and facilitates surgery; the surgery time is short, the paining of a patient is low, the labor intensity of doctors is low, the esophageal stent can be reused after being recycled, and the treatment cost of the patient can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nickel-titanium memory alloy esophageal stent placement recovery device used under X-ray perspective. Background technique [0002] If the human esophagus becomes cancerous, it will block the esophagus, causing the patient to be unable to swallow food and die of hunger. In order to prolong the life of the patient, the existing technology is to place a nickel-titanium memory alloy esophageal stent on the esophageal lesion to support the esophagus. To expand the lumen diameter of the diseased esophagus to facilitate the passage of food. The placement of this esophageal stent is performed with the help of a gastroscope, but the problem is that after the placement of the Nitinol esophageal stent, many patients The cancerous part of the esophagus blocked the esophagus, causing difficulty in swallowing food. After X-ray perspective, it was found that the nickel-titanium memor...

[0002] If the human esophagus becomes cancerous, it will block the esophagus, causing the patient to be unable to swallow food and die of hunger. In order to prolong the life of the patient, the existing technology is to place a nickel-titanium memory alloy esophageal stent on the esophageal lesion to support the esophagus. To expand the lumen diameter of the diseased esophagus to facilitate the passage of food. The placement of this esophageal stent is performed with the help of a gastroscope, but the problem is that after the placement of the Nitinol esophageal stent, many patients The cancerous part of the esophagus blocked the esophagus, causing difficulty in swallowing food. After X-ray perspective, it was found that the nickel-titanium memory alloy esophageal stent was pushed down into the stomach due to esophageal peristalsis and swallowing coarse food. The current solution is to use special scissors. With the help of the gastroscope, the cutting instrument cut the nitinol esophageal stent bit by bit, and then took it out piece by piece through the biopsy forceps, and then placed a new nitinol esophageal stent. The operation was very complicated, and the patient It is very painful, and the long-term operation increases the labor intensity of the doctor and increases the treatment cost of the patient. There is no good solution yet
