Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical appliances, in particular to a weight loss balloon bracket. Background Art
[0002] Obesity and related health problems have become a global public health challenge, with serious impacts on personal health and medical resources.
[0003] Traditional bariatric surgeries such as gastric bypass and gastrectomy, although effective in reducing weight, are accompanied by certain surgical risks, postoperative complications, and long-term lifestyle changes. These surgeries are prone to malnutrition, indigestion, and other adverse reactions, limiting the willingness of some patients to undergo such treatments.
[0004] Based on the above problems, a weight loss balloon stent is proposed to improve the problems in the prior art. Summary of the invention
[0005] In view of the deficiencies of the prior art, the present invention provides a weight loss balloon stent, which solves the problem that the adverse reactions after the prior weight loss surgery are relatively serious and the patients' willingness to accept the surgery is reduced.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a weight loss balloon bracket, including a balloon body, a balloon wall is arranged inside the balloon body, a connecting band is fixedly connected to one side of the balloon body, a one-way valve is arranged on the front side of the balloon body, a positioning band is fixedly connected to the rear side of the connecting band, and a bracket is fixedly connected to the rear side of the positioning band.
[0007] Preferably, the capsule is made of silica gel, and the middle portion of the capsule is communicated with the bracket after being expanded by water injection.
[0008] Preferably, the connecting belt and the positioning belt are made of polyethylene.
[0009] Preferably, the capsule wall is funnel-shaped after the capsule body is deformed.
[0010] Preferably, the bracket is made of nickel-titanium alloy.
[0011] Preferably, the filling liquid of the balloon is physiological saline.
[0012] Working principle: When placing the weight loss balloon stent in the patient's body, the medical staff will first anesthetize the patient to reduce the patient's discomfort during the operation. Then, the wire is positioned through the endoscope and buried in the middle of the duodenum. After this step is completed, the balloon, positioning belt, and stent assembly are pushed into the patient's stomach through the wire and endoscope. During the operation, it is necessary to ensure that the positioning belt is correctly inserted into the pylorus, the stent enters the duodenum smoothly, and gradually unfolds with intestinal peristalsis. At this point, the initial placement of the weight loss balloon stent has been completed.
[0013] After placement, the guidewire is removed through an endoscope. Next, normal saline is injected into the sac through the tube reserved by the one-way valve. As the sac expands, the volume of the sac in the patient's stomach gradually increases, effectively improving the patient's sense of fullness. During subsequent eating, some food will pass through the funnel-shaped structure of the sac wall, the connecting belt, the positioning belt, and the stent, and enter the posterior duodenum. This process helps reduce intestinal absorption.
[0014] When the weight loss balloon stent needs to be removed, the balloon can be broken up by using an endoscope and a biopsy clip, so that the volume of the stomach occupied by the stent is reduced, making it easier to remove the balloon and stent from the esophagus.
[0015] The present invention provides a weight loss balloon stent, which has the following beneficial effects: 1. The present invention can replicate the mechanism of gastric bypass surgery without cutting or suturing through the coordinated use of components such as the capsule body, the capsule wall, and the one-way valve, and can achieve the same endoscopic surgery as gastric bypass surgery, thereby reducing trauma.
[0016] 2. The present invention can effectively shorten the overall operation time by using the positioning belt, the stent and other components in coordination, and can remove the stent and the capsule without secondary trauma during the removal operation, thereby reducing the psychological burden on the patient.
[0017] 3. The present invention can have a positive impact on the patient's metabolism, including regulating blood sugar levels and improving insulin sensitivity indicators, by using the capsule, stent, positioning belt and other components in combination, thereby helping patients achieve long-term weight loss goals.

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0021] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a weight loss balloon bracket 6, including a balloon body 1, a balloon wall 2 is arranged inside the balloon body 1, the filling liquid of the balloon body 1 is physiological saline, a connecting belt 4 is fixedly connected to one side of the balloon body 1, a one-way valve 3 is arranged on the front side of the balloon body 1, a positioning belt 5 is fixedly connected to the rear side of the connecting belt 4, the connecting belt 4 and the positioning belt 5 are made of polyethylene, and a bracket 6 is fixedly connected to the rear side of the positioning belt 5, and the bracket 6 is made of nickel-titanium alloy. The nickel-titanium alloy material has certain ductility and durability and can adapt to physiological activities such as intestinal peristalsis.
[0022] First, the patient needs to be anesthetized to reduce discomfort during the operation. Then, an endoscope is used to position the guidewire. After it is buried in the middle of the duodenum, the combination of the capsule 1, the positioning belt 5, and the stent 6 is pushed into the patient's stomach through the guidewire and the endoscope until the positioning belt 5 is stuck in the pylorus and the stent 6 enters the duodenum and gradually unfolds with intestinal peristalsis, thereby completing the initial placement.
[0023] After the placement is completed, the guide wire is removed through an endoscope, and normal saline is injected into the balloon 1 through the pipeline reserved by the one-way valve 3. As the balloon 1 expands, its volume in the patient's stomach gradually increases, which can effectively increase the patient's sense of fullness. During the patient's subsequent eating process, part of the food can be transported to the back of the duodenum through the connecting belt 4, the positioning belt 5 and the bracket 6 through the funnel shape presented by the deformation of the balloon wall 2, thereby reducing intestinal absorption.
[0024] When it is necessary to remove it, the capsule 1 can be broken up by using an endoscope in combination with a biopsy clamp to reduce the volume occupied by the stomach, and the capsule 1 and the stent 6 can be removed from the esophagus.
[0025] The capsule 1 is made of silicone material, which has good biocompatibility, little stimulation to human tissue, and is not easy to cause rejection reaction, and is suitable for long-term use in the human body. After the capsule 1 is filled with water and expanded, the middle part is connected with the bracket 6. The capsule wall 2 is funnel-shaped after the capsule 1 is deformed, and the funnel-shaped design allows food to pass normally.
[0026] Experimental content: Eight pigs were included in this study and divided into a control group and a sham operation group, with a random allocation of 1:1. The control group used the device of the present invention.
[0027] Observation contents: body weight, food intake, blood glucose level, insulin-mediated glucose uptake, endogenous glucose production, whole body insulin sensitivity, liver insulin sensitivity, insulin secretion, insulin clearance, and complications.
[0028] The experimental research results are tabulated as follows: Summarize: The weight gain in the experimental group was reduced by 79%, which was mainly due to a 22% reduction in food intake and increased fecal nutrient losses due to incomplete food digestion. Secondly, blood glucose levels were significantly reduced in the control group surgery, and insulin-mediated glucose uptake and endogenous glucose production were significantly increased. In addition, systemic and hepatic insulin sensitivity was also significantly increased, insulin secretion was reduced, insulin clearance was improved, and no surgery-related complications occurred in the control group surgery.
[0029] The control group showed better results in weight control and food intake compared to the sham operation group. Compared with the traditional gastric bypass surgery, the present invention can achieve similar results without the need for surgical operation or cutting of internal organs.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
