Volume-reducing stomach stent

Abstract

The invention discloses a volume-reducing stomach stent, which comprises an upper circle (2), a lower circle (6), bone weft lines (3) and bone warp lines (4), wherein the upper circle (2), the lower circle (6), the bone weft lines (3) and the bone warp lines (4) are made of elastic metal alloy wires; the bone warp lines are in circular arc-shaped separated arrangement; one end of each bone warp line is connected with the upper circle, and the other end of each bone warp line is connected with the lower circle; the bone weft lines are arranged on the bone weft lines at intervals in a spiral shape; the volume-reducing stomach stent can be released into an oval spherical net cover in a gastral cavity (1) through the gullet by a releaser, can also be folded into a strip shutter shape in the gastral cavity by a recoverer and can be taken out from the gastral cavity. The volume-reducing stomach stent can enter the gastral cavity in a contracted state, and then can be elastically released in the stomach; micro diameter nickel-titanium alloy wires are used and are woven into spherical reticular structures; sufficient radial tension and good compliance are realized for evenly supporting the stomach wall; thus the full feeling is generated; the eating quantity is reduced; the fat losing effect is achieved. Meanwhile, the untoward effect of a fat loser can be effectively prevented; the production cost is low; the storage period is not limited; damage cannot easily occur; the applicability is high; the risk is small.

Description

technical field [0001] The invention relates to a medical appliance, which belongs to a spherical gastric support for reducing the volume of the gastric cavity. Background technique [0002] As we all know, the stomach is the enlarged part of the alimentary canal, and it is the main organ for accommodating food. The material basis of obesity is a large amount of food intake and greater intake than consumption. With the changes in people's living standards and lifestyles, the number of obese people is increasing day by day, and related metabolic diseases are also high. Under normal circumstances, obese people eat more food, which means that the stomach cavity volume is relatively larger. In order to lose weight, especially for obese people who do not do physical work, it is generally achieved by increasing exercise, diet, and some surgical operations. However, if the exercise does not reach a certain amount and the time cannot last, the weight loss effect will be unsatisfac...

AI Technical Summary

Problems solved by technology

Its gastric volume reduction and weight loss effect is obvious, but there are disadvantages such as large surgical trauma, irreversibility, high risk and cost; Place a water polo (gastric balloon, a product approved and registered by the US FDA in 2015) to reduce stomach volume and desire to eat, thereby reducing food intake to achieve weight loss

Although the weight-loss effect of placing the water balloon in the stomach is better, there are still the following problems in actual use: First, the weight of the gastric balloon after injecting 500 to 700 ml of water is heavy, and it is difficult to place it in the gastric cavity due to compression. Some people may have adverse reactions such as stomach cramps, abdominal distension, abdominal pain, and vomiting; second, the weight of the gastric balloon may cause serious complications such as gastric erosion and ulcers due to long-term compression of the gastric mucosa; third, the use of polymer materials (polyurethane, It is made of silicone rubber, etc.), and it is easy to disintegrate and break in an acidic environment, so the time limit for internal placement in the body (<6 months); Fourth, the current gastric balloon needs to be imported from abroad, the price is high, and it is difficult for obese people to Acceptable, not conducive to promotion and popularization
