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.
