Spherical scaffold used in stomach

Abstract

The invention discloses a spherical scaffold used in the stomach. The spherical scaffold used in the stomach is made of metal alloy wires comprises an upper circle (1), a lower circle (4), a bone longitude line (2) and a bone latitude line (3), wherein the upper circle is opposite to the lower circle, the bone longitude lines are spaced in an arc shape, one end of each bone longitude line is connected with the upper circle, and the other end is connected with the lower circle; the bone latitude lines and the bone latitude lines are interwoven spirally at equal intervals to form a grid; the spherical scaffold used in the stomach is in a net shape in the relaxation state and in a cylindrical pipe shape in the contraction state. The spherical scaffold used in the stomach has the smooth surface, has characteristics of softness and elasticity and can perform passive peristalsis in the gastric cavity along with stomach peristalsis, besides, the spherical scaffold is changeable in the stomach due to the wet and smooth internal environment secreted by gastric mucosa, cannot be inlaid in the gastric cavity or embedded by the gastric mucosa, can be taken out conveniently at any time under the assistance of a gastroscope and can be reused, and bad reactions and obesity bounce on a dieter during usage can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric spherical stent used for reducing the volume of the stomach so as to achieve the effect of dieting and losing weight. Background technique [0002] The stomach is the organ that holds food in the human body, and the volume of the stomach directly determines people's appetite and food intake. A large amount of food intake, resulting in "intake greater than consumption" is the material basis of obesity. With the improvement of people's living standards and lifestyle changes, the number of obese people is increasing day by day, and obesity-related metabolic diseases are also on the rise. Under normal circumstances, obese people eat more food, which means that the stomach cavity volume is relatively larger. Reducing the volume of the gastric cavity in a non-invasive way is an effective means and development direction of dieting and losing weight. [0003] In dail...

AI Technical Summary

Problems solved by technology

Although the weight loss effect of placing the water balloon in the stomach is better, there are still the following problems in actual use: 1. The gastric water balloon is heavy after being injected with 500-700 ml of water, and it is placed about 20% of the back of the gastric cavity. People will have unbearable abdominal pain, abdominal distension, vomiting and other adverse reactions, and those who lose weight are forced to take out the water balloon in advance to stop the treatment; 2. Long-term compression of the gastric mucosa by the gastric water balloon is likely to cause serious complications such as gastric erosion and ulcers; 3. The balloon Made of polymer materials (polyurethane, silicone rubber, etc.), it is easy to disintegrate and break in an acidic environment, so the time limit for internal placement in the body is limited (< 6 months); 4. At present, gastric balloons need to be imported from abroad. The price is high, which is unbearable for the general obese people, which is not conducive to promotion and popularization
