Implanting instrument capable of preventing gastroesophageal reflux

Abstract

The invention relates to an implanting instrument capable of preventing gastroesophageal reflux. The implanting instrument comprises a magnetic chain and auxiliary lines, the magnetic chain comprises multiple magnetic devices, multiple connecting units and a lock catch device, each magnetic device comprises one or more annular magnets and a shell, and the internal circumferential face of each shell is an internal concave cambered surface; the adjacent magnetic devices are movably connected through one connecting unit, and each connecting unit comprises a connecting part and limiting parts arranged at the ends of the connecting part; the lock catch device comprises a first lock catch device body and a second lock catch device body, the magnetic chain is further provided with a starting magnetic device and a tail end magnetic device, the first lock catch device body and the second lock catch device body are arranged on a shell of the starting magnetic device and a shell of the tail end magnetic device respectively, and when the first lock catch device body and the second lock catch device body are combined, a closed annular magnetic chain ring is formed by the magnetic chain. According to the implanting instrument capable of preventing the gastroesophageal reflux, the design is reasonable, and the shape formed by connecting the magnetic chain in series is closer to a circle, so that the implanting instrument is more attached to the outer wall of esophagus after being implanted to the outer side of lower esophageal sphincter, and the effect of strengthening the LES through the instrument is exerted more sufficiently.

Description

technical field [0001] The invention relates to a medical implant device, more specifically, to an implant device for resisting gastroesophageal reflux. The implant device of the present invention surrounds the patient's lower esophageal sphincter outside the lower esophageal sphincter through laparoscopic surgery, so as to enhance the closing ability of the lower esophageal sphincter and play a role in resisting the reflux of gastric contents. Background technique [0002] Gastroesophageal reflux disease (GERD) refers to the reflux of excessive contents of the stomach and duodenum into the esophagus, causing symptoms such as heartburn, and can lead to esophagitis and tissue damage outside the esophagus such as the pharynx, larynx, and airway. Gastroesophageal reflux disease is very common in western countries. About 7% to 15% of the population has gastroesophageal reflux symptoms. The incidence increases with age. The peak age of onset is 40 to 60 years old. For patients w...

Problems solved by technology

But its disadvantages are as follows: firstly, the formed ring is not round enough to fit well with the outside of the lower esophageal sphincter. When the patient swallows food, the esophageal expansion will rub against the instrument, causing discomfort to the patient, and even worse, causing the patient’s esophageal Symptoms such as inflammation on the outer side of the lower sphincter; secondly, it is inconvenient to connect the two ends of the head and tail, which is not conducive to the doctor's operation and increases the operation time; thirdly, after the magnetic bead chain is implanted in the body for a period of time, the magnetic beads and the gap between the adjacent magnetic beads The gap will be wrapped and buried by human tissue, once the patient is found to be unwell, it will be difficult to remove
