Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an anti-gastroesophageal reflux implantable device for clinical use in gastroenterology. Background Technology

[0002] Gastroesophageal reflux disease (GERD) is a common digestive disorder that occurs when stomach acid or contents reflux into the esophagus, causing irritation and damage to the esophageal mucosa. Patients typically experience symptoms such as chest pain, heartburn, and difficulty swallowing. If left untreated, it can lead to esophagitis, ulcers, and even increase the risk of esophageal cancer. Traditional treatments for GERD usually rely on medications such as proton pump inhibitors (PPIs) or H2 receptor antagonists to reduce stomach acid secretion. However, long-term use of these medications can lead to dependence and may have side effects such as intestinal infections and an increased risk of fractures. Patients need to control their symptoms by changing their eating habits, losing weight, and avoiding lying down and sleeping immediately. However, these changes are not always easy to maintain and have limited effectiveness for some patients.

[0003] Therefore, those skilled in the art provide an anti-gastroesophageal reflux implantable device for clinical use in gastroenterology to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clinical anti-gastroesophageal reflux implantable device for gastroenterology. Through its chain-body design, it effectively fixes the stomach and esophagus, preventing gastric acid reflux and thus alleviating gastroesophageal reflux symptoms. The chain-body consists of an adjustable number of first and second connectors, which are interconnected via snap-fit ​​mechanisms, allowing doctors to make personalized adjustments based on the patient's esophageal size. Furthermore, the device's snap-fit ​​components, connectors, return springs, and telescopic rods feature a rapid connection and fixation mechanism that not only simplifies surgical procedures and shortens surgical time but also ensures long-term stability of the connection through the return springs, reducing the risk of component loosening and improving surgical safety and efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An anti-gastroesophageal reflux implantable device for clinical use in gastroenterology includes a chain body. The chain body comprises multiple first connectors and multiple second connectors. Each of the outer walls on one side of the first connector has a connecting groove in the middle of both sides. Each of the upper surfaces of the first connector has a sliding groove in the middle of both sides. The lower end of each sliding groove penetrates the connecting groove into its interior. Each of the upper surfaces of the first connectors has two mounting grooves in the middle of both sliding grooves. Each of the first connectors has a snap-fit ​​component at its upper end. Each mounting groove has a telescopic rod inside its interior. The lower end of each telescopic rod is fixedly connected to the inner bottom surface of the mounting groove. The upper end of each telescopic rod is fixedly connected to the lower surface of the middle of the snap-fit ​​component. Each telescopic rod is fitted with a return spring. Each of the second connectors has a connecting rod fixedly connected to the middle of both sides of its outer wall on the other side. Each connecting rod has a snap-fit ​​groove in its middle.

[0007] Through the above technical solution and the design of the chain body, we can effectively fix the stomach and esophagus together, thereby preventing gastric acid reflux into the esophagus and alleviating the symptoms of gastroesophageal reflux disease. The chain body consists of a series of first and second connectors, which are connected to each other by snap-fit. Doctors can flexibly reduce or increase the number of first and second connectors according to the specific size of the patient's esophagus to achieve appropriate fastening of the stomach and esophagus. Furthermore, the quick connection and fixation mechanism between components such as snap-fit, connectors, return springs, and telescopic rods simplifies the surgical procedure and shortens the operation time. In addition, the return springs ensure the long-term stable connection between the snap-fit ​​and the connecting rods, reducing the loosening of components due to movement or the passage of time.

[0008] Furthermore, two T-slots are formed in the middle of the outer walls of adjacent sides of the first connector and the second connector, and a rubber rope is provided in the middle of the first connector and the second connector. Limiting blocks are fixedly connected to both sides of the outer wall of the rubber rope, and the outer walls of the limiting blocks are engaged with the inner walls of the T-slots.

[0009] Through the above technical solution, the rubber rope has good elasticity and good biocompatibility. It can stretch under the action of external force and then return to its original shape after the force is removed. This elasticity allows the rubber rope to adapt to internal movements, such as swallowing, coughing or physical activities, without causing excessive pressure on surrounding tissues.

[0010] Furthermore, a pull ring is fixedly connected to the middle of the upper surface of each snap-fit ​​component;

[0011] With the above technical solution, doctors can easily grasp and manipulate the connectors using the pull ring during surgery, thereby quickly completing connection or adjustment operations.

[0012] Furthermore, the outer walls on both sides of the lower end of the snap-fit ​​component are slidably fitted against the inner wall of the sliding groove;

[0013] The above technical solution and design ensure that the snap-fit ​​component can move smoothly within the sliding groove during the use of the instrument.

[0014] Furthermore, the upper ends of the reset springs are all fixedly connected to the lower surface of the snap-fit ​​component, and the lower ends of the reset springs are all fixedly connected to the inner bottom surface of the mounting groove.

[0015] The above technical solution ensures a long-term stable connection between the snap-fit ​​component and the connecting rod by using a return spring, reducing component loosening caused by movement or the passage of time.

[0016] Furthermore, the outer walls of the connecting rods are all tightly fitted to the inner walls of the connecting grooves, and the outer walls on both sides of the lower end of the snap-fit ​​component are snap-fitted into the inner walls of the snap-fit ​​grooves.

[0017] The above technical solution simplifies the surgical procedure and reduces the operation time by quickly connecting and fixing various components such as snap-fit ​​parts, connecting rods, return springs, and telescopic rods.

[0018] This utility model has the following beneficial effects:
