Description

An endoscope weight-reducing device and its working method

technical field

The invention belongs to the field of endoscope equipment, and in particular relates to an endoscope weight reduction device and a working method thereof.

Background technique

The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

In recent years, obesity and obesity-related diseases have gradually become a worldwide health problem. Obesity-related diseases such as hypertension, coronary heart disease, diabetes, sleep apnea, etc. have seriously affected people's quality of life and caused a huge medical burden. Effective weight loss measures can solve this problem from the source, and the development of new and efficient weight loss measures has become a research hotspot. At present, weight loss measures mainly include lifestyle modification, drug weight loss and weight loss surgery. Simple lifestyle adjustments have limited effect and are not suitable for severely obese individuals. Although the effect of drug weight loss is slightly better than that of simple lifestyle adjustment, it has relatively many adverse reactions. Bariatric surgery is still the main method to achieve efficient weight loss. The weight loss effect through surgical operations is remarkable, and currently, sleeve gastrectomy and gastric bypass surgery are the main methods. However, surgical procedures are costly and risky, and are often difficult for patients to accept.

With the growing demand for minimally invasive weight loss, endoscopic weight loss came into being. Similar to the principle of surgical weight loss, endoscopic weight loss achieves weight loss by reducing the volume of the digestive tract or affecting food absorption. Duodenal-Jejunal Bypass Sleeve simulates Roux-en-Y surgery. By placing the sleeve in the duodenum and upper jejunum, food is isolated from the intestine and affects the flow of food. Absorption, has a good weight loss effect. However, the inventors found that due to the defects of the fixed placement of the device, the duodenal bulb mucosa will be greatly damaged during the use of the device. In addition, if the device is displaced with intestinal peristalsis, it will cause more and greater damage to the intestinal mucosa, and even lead to the occurrence of pancreatitis. This defect affects the application of duodenum-jejunum sleeves to some extent.

FIG. 1 is a schematic structural diagram of an endoscope weight-reducing device according to the present embodiment.

The structure of an endoscope weight reduction device according to this embodiment will be described in detail below with reference to FIG.

Wherein, the elastic member 2 is arranged between the fixing assembly 1 and the cylindrical body 3;

A continuous cavity is formed inside the fixing assembly 1, the elastic member 2 and the cylindrical body 3; wherein, the cylindrical body 3 has elasticity and the shape can match the shape of the duodenum and the small intestine below;

The fixing assembly 1 is provided with a helical track 5, and a guide wire 4 can be embedded in the helical track 5, and the guide wire 4 is used to support the fixing assembly 1, so that the fixing assembly 1 has elasticity.

In a specific implementation, the cylindrical body 3 is a transparent structure of a sleeve. The cylindrical body 3 is a transparent, soft device that does not damage the mucous membrane of the digestive tract. When it is in the intestinal tract, it does not affect the peristalsis of the intestinal tract; when the food passes through its surface, it will not stick or stagnate. Among them, the structure of the sleeve is similar to that of the intestine, and it can be made of non-biotoxic materials, such as polytetrafluoroethylene.

In a specific implementation, the fixing component 1 is a hollow structure, and in order to better fit with the gastric antrum, the shape of the fixing component 1 is a funnel.

The fixing assembly 1 includes an outer buffer layer and an inner support layer. The surface of the buffer layer is covered with a smooth material to reduce friction with the mucous membrane; the support layer is provided with a spiral track 5, which is soft and foldable before inserting the guide wire. .

As shown in FIG. 2 , the end of the spiral track 5 is further provided with a track lock 6 , and the track lock 6 is used to block the end of the spiral track. After the track lock 6 is closed, the guide wire is prevented from coming out. The fixing assembly 1 is located at the head end of the endoscopic weight-reducing device, and is used to fix the entire device in the digestive tract.

It should be noted here that the buffer layer is composed of a material with a buffer function, such as a silicone material.

In a specific implementation, the elastic member is provided with an elastic material with a set elastic coefficient, which can be extended when subjected to force, and slowly contracted when not subjected to force, which has a traction effect on the fixed component at the front end.

By changing the length and shape of the elastic piece, it can adapt to the peristalsis of the digestive tract and play a buffering role. For example, the elastic member can be realized by adopting a corrugated tube or a structure whose length and shape can be changed.

When outside the body, the device is in its initial state - the guide wire 4 is outside the device, and the device is small when folded. Under the direct view of the digestive endoscope, the device is placed into the digestive tract, the fixing component 1 is located in the stomach, and forms a shape adapted to the gastric antrum according to its own elasticity, the elastic member 2 is located at the pylorus, and the cylindrical body 3 is located in the duodenum. The cylindrical body 3 is unfolded using a catheter. Put the guide wire 4 into the spiral track 5 and close the track lock 6 . Angiography and X-ray examination were performed to observe the placement of the device.

The device will detect small changes in the position of the peristalsis of the gastrointestinal tract. After eating, the food is thoroughly mixed in the stomach to form chyme. One part enters the cavity of the fixation assembly 1, and the other part enters the duodenum through the normal route. When the gastric antrum contracts and the pylorus is closed, the fixing component 1 and the elastic member 2 are compressed and stretched, and the fixing component 1 leaves the gastric antrum and moves toward the gastric body. At this time, the gastric antrum and pyloric mucosa will not rub and collide with the device. When the gastric antrum is dilated and the pylorus is opened, the pressure of the fixing assembly 1 and the elastic member 2 disappears, and the fixing assembly 1 will return to the gastric antrum along with the peristalsis of the stomach and the traction of the elastic member 2 . The food entering the device will enter the cylindrical body 3 along the cavity, and finally enter the digestive tract at the end of the cylindrical body 3 .

During the application of the device, the digestive endoscope and X-ray are regularly used to observe whether the position shift occurs, and whether there is any side effect. When the device has been in the body for a certain period of time, it needs to be taken out under direct vision of the endoscope. By taking out the guide wire and putting the entire device in the storage bag, it is taken out with an endoscope.

The working method of the endoscope weight reduction device of the present embodiment includes:

S1: Put the endoscopic weight-reducing device into the digestive tract, so that the fixing component is located in the gastric antrum, the elastic piece crosses the pylorus, and the cylindrical body is located in the duodenum and the small intestine below; The wire is placed in the spiral track, and the track lock is closed;

In specific implementation, step S1 also includes:

Under the direct vision of digestive endoscope, angiography and X-ray examination were performed to observe the placement of the endoscopic weight loss device.

S2: When the gastric antrum is peristaltic and the pylorus is contracted and closed, the contraction force acts on the fixed component and the elastic member, the elastic member is elongated, and the fixed component leaves the original position. At this time, the gastric antrum and the pylorus are compressed and elongated elastic members , and then, when the gastric antrum dilates and the pylorus opens, the fixing device returns to the gastric antrum again under the push of gastric peristalsis wave and the direction of elastic member, and the position of the cylindrical body will move slightly during this process;

S3: After eating, the food forms chyme in the stomach, and it is gradually emptied with the peristalsis of the stomach. The chyme partially enters the cavity of the fixed component, and gradually descends into the cavity of the elastic member and the cylindrical body, and finally , enter the intestine after passing through the entire endoscopic weight loss device;

S4: The process of the above steps S2-S3 is repeated continuously.

In this embodiment, the device is fixed in the digestive tract without external force by utilizing the change of the inner diameter of the natural lumen. The damage of the device to the mucosa is minimized through the buffering effect and elasticity of the fixing component itself and the length change of the elastic member. It has a good weight loss effect by occupying space in the stomach and reducing food absorption, and truly achieves safe and effective weight loss.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
