Problems solved by technology

[0005] 1. The materials in contact with the tissue are all metal materials, and the formed ring is not round enough to fit well with the outer side of the lower esophageal sphincter. When the patient swallows food, the esophageal dilation will rub against the instrument, causing discomfort to the patient, and even worse. It can cause symptoms such as inflammation on the outer side of the lower esophageal sphincter;
[0006] 2. The implanted device does not have the ability to expand outward, which may easily cause the sphincter to expand unsmoothly;
[0007] 3. The implanted device is not fixed with the sphincter, which may easily cause position deviation and affect the use effect

no. 1 example

[0058] The auxiliary device for enhancing sphincter function of the first embodiment provided by the present invention (hereinafter simply referred to as the device) is as follows: Figure 1b As shown, the device was placed lateral to the sphincter ( Figure 1a The schematic diagram is the gastroesophageal lower sphincter, the device can also be used in the urethral sphincter, anal sphincter and other sphincters in the human body), including two magnetic devices 2 that can attract each other, and a buffer placed between the two magnetic devices 2 Device 3, a fixing piece 4 for fixing the two magnetic devices 2 to the sphincter, the two ends of the buffer device 3 can be respectively in contact with the adjacent magnetic devices 2, the magnetic device 2 is arranged on the outside of the sphincter, when the When the sphincter is closed, the two magnetic devices 2 that attract each other approach each other, compress the buffer device 3, and cause the buffer device 3 to deform; wh...

no. 2 example

[0069] Such as Figure 5a and Figure 5b As shown, based on the first embodiment, the first difference between the second embodiment and the first embodiment is: the buffer device 3 also includes a limiting device 32, and the two ends of the limiting device 32 It is connected with adjacent magnetic devices 2 so as to limit the maximum distance between two magnetic devices 2 that are attracted to each other. This design has the following advantages: 1. The device forms a closed loop, which is more helpful for the device to be close to the outside of the sphincter and maximize the efficacy of the device; 2. It is beneficial for the device to be on a predetermined plane for a long time, avoiding The misplaced attraction of other magnetic devices 2 causes the device to work disorderly, so as to further ensure that the device continues to play the preset role; 3. Avoid the need to use additional fixing parts 4 to fix the buffer device 3 on the outside of the sphincter in the desig...

no. 3 example

[0074] Based on the second embodiment, the difference between the third embodiment and the second embodiment is that the cushioning device 3 is a mesh structure 35 made of elastic material (such as Figure 7a and 7b shown) or cystic structures 36 (such as Figure 7c shown) or tubular structure 37 (such as Figure 7d and Figure 7e shown) or porous structure 38 (such as Figure 7f shown). Under the action of the two magnetic devices 2, the mesh structure 35 or the capsule structure 36 or the porous structure 38 can be deformed, such as Figure 7b As shown, under the condition of no force, the network structure 35 or the capsule structure 36 or the porous structure 38 can return to Figure 7a or Figure 7c or Figure 7f The original state, so it plays a similar or the same effect as a spring. The mesh structure 35 can be woven from elastic material, or cut and shaped from a shape memory alloy tube. The porous structure 38 can be integrally formed by polymer elastic mate...

Abstract

The invention relates to an auxiliary device for enhancing the sphincter function. The device comprises at least two attracted magnetic devices, a buffer device arranged between the two magnetic devices, and a fixing piece for fixing the magnetic devices and the sphincter, the two ends of the buffer device can make contact with the adjacent magnetic devices, the magnetic devices are arranged on the outer side of the sphincter, when the sphincter is closed, the two attracted magnetic devices get closer, the buffer device is compressed, and the buffer device deforms; when the sphincter is expanded, the buffer device can help the two attracted magnetic device to get away from each other. The sphincter can be helped to be closed, sphincter expansion is not affected, the device is good in fitting adaptability with the outer side of the sphincter, motor coordination with closure and expansion of the sphincter is achieved, the whole structure is stable, the space configuration is in order, fixed non-wound can be achieved, surgical operation is simple, and the safety is high.

Description

technical field [0001] The present invention relates to the technical field of treatment of reduced sphincter function, in particular to an auxiliary device for enhancing sphincter function. The device is embedded outside the sphincter in the human body and can replace the sphincter function of cardia, pylorus, ileocecal, anal canal, urethra, etc. Strengthen or rebuild the sphincter ability of organs with weakened or lost sphincter strength, and control the normal flow and excretion of contents in the digestive tract and urinary tract. Background technique [0002] The sphincter is a circular muscle distributed in the walls of certain lumens in humans and animals, and plays a vital role in controlling the normal flow of lumen contents. In humans, sphincters are found in the digestive tract and urinary system. When the sphincter contracts, it closes the lumen, and when it relaxes, it opens the lumen, and it is usually closed. The lower esophageal sphincter in the gastroesop...
