Embodiment 1

[0042] see figure 1 , the intragastric stent weight loss device provided in this embodiment assists obese patients to lose weight through safe and non-invasive treatment.

[0043] It should be noted that with the improvement of people's living standards, the number of obese people is increasing. Among them, obesity, as a risk factor for many chronic diseases such as hypertension, diabetes, cardiovascular and cerebrovascular accidents, and malignant tumors, has been listed as one of the top ten risk factors leading to disease burden.

[0044] At present, there are not many treatment methods for obesity. Due to the corresponding level of cognition, traditional concepts, medical resources and other reasons, people's recognition of surgical treatment is not high, and even fewer patients can accept it. In this embodiment, the intragastric stent weight loss device provided has low surgical risk and does not cause surgical complications and other problems during obesity treatment. ...

Abstract

The invention provides an intragastric stent weight loss device, which relates to the technical field of medical devices. The intragastric stent weight loss device includes a delivery structure, a gastric stent structure and a filling structure; the delivery structure is used to deliver the gastric stent structure and filling structure into the stomach, and the delivery structure includes a delivery catheter and a shrinking capsule connected to the delivery catheter; the gastric stent structure can be detached The filling structure is arranged on the delivery structure, and the filling structure includes a releasable elastic filling ring, and the elastic filling ring is located at the end of the shrinking balloon away from the delivery catheter. After the gastric stent structure and elastic filling ring are implanted through the gastric stent weight loss device provided by the application, the gastric stent structure can realize the positioning of the elastic filling ring in the patient's stomach, and prevent the elastic filling ring from blocking food after displacement. At the same time, the elastic filling ring provides the patient with a sense of satiety, thereby reducing the food intake of the patient, so as to achieve the purpose of weight loss, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intragastric stent weight loss device. Background technique [0002] Obesity is a common group of metabolic disorders. As a risk factor for many chronic diseases such as hypertension, diabetes, cardiovascular and cerebrovascular accidents, and malignant tumors, obesity has been listed as one of the top ten risk factors leading to disease burden. [0003] At present, minimally invasive bariatric surgery for obesity is easily accepted by people. When performing minimally invasive bariatric surgery, the patient first needs to swallow the uninflated balloon into the stomach, and then inject a marked liquid into the balloon to inflate the balloon. In the event of early unanticipated balloon rupture, marked fluid may be detected in the patient's urine, and the ruptured balloon should be removed from the stomach as soon as possible. Due to the minimally invasive intragastri...
