Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of artificial food and gastric tube sphincter, in particular to a magnetic control type artificial food and gastric tube sphincter. BACKGROUND

[0002] When food enters the esophagus, it stimulates the mechanical receptors on the esophageal wall, which reflexively causes the lower esophageal sphincter to relax, allowing food to enter the stomach. After the bolus enters the stomach, the lower esophageal sphincter contracts, restoring its resting tone, which prevents gastric contents from refluxing into the esophagus. Patients with esophagogastric junction adenocarcinoma and other diseases related to the esophagogastric and gastric sites often cannot eat normally due to the effects of the disease, and need to use a special liquid gastric tube for assisted eating. The uneven nutrition of food brought by this eating method cannot meet the nutritional needs of patients recovering.

[0003] The existing special patients usually cannot simulate the relaxation and contraction of the normal eating sphincter when eating, which affects the recovery of the patients; therefore, the existing needs are not met, and for this purpose, a magnetic control type artificial food and gastric tube sphincter is proposed. SUMMARY

[0004] The purpose of the present application is to provide a magnetic control type artificial food and gastric tube sphincter to solve the problem that special patients usually cannot simulate the relaxation and contraction of the normal eating sphincter when eating, which affects the recovery of the patients, and other problems raised in the background art.

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] See also Figures 1 to 4 The present invention provides an embodiment: a magnetically controlled artificial esophageal sphincter, comprising a gastric tube 1, a stomach 2 being provided at the bottom end of the gastric tube 1, a silicone sleeve 3 being movably mounted on the outer surface of the gastric tube 1, one end of the silicone sleeve 3 being fixedly connected to a connecting ring 4, the other end of the silicone sleeve 3 being movably passed through the center of the connecting ring 4, a fixed sleeve 6 being movably mounted on the other end of the silicone sleeve 3, a silk rope 10 being provided inside the silicone sleeve 3, the silk rope 10 being in contact with the surface of the gastric tube 1, and the surface of the silk rope 10 being in contact with the gastric tube 1 being wrapped with silicone.

[0016] Through the cooperation of the silicone sleeve 3 and the silk rope 10, the device can be installed at the patient's gastric sphincter position, and the push-pull electromagnet 7 drives the silicone sleeve 3 to tighten and prevent loosening to achieve the relaxation and contraction of the sphincter, thereby meeting the eating needs and avoiding the situation where the patient is unable to eat independently.

[0017] A push-pull electromagnet 7 is provided inside the fixed sleeve 6, and a micro spring 9 is movably installed on the outer surface of the output end of the push-pull electromagnet 7. The output end of the push-pull electromagnet 7 is movably connected to the other end of the silicone sleeve 3, and one end of the wire rope 10 is movably inserted into the output end of the push-pull electromagnet 7. The wire rope 10 and the output end of the push-pull electromagnet 7 are fixedly connected by bolts.

[0018] The connecting sleeve 5 is fixedly installed on the outer side of the fixing sleeve 6 , and the other end of the silicone sleeve 3 is movable through the center of the connecting sleeve 5 , and the rear surface of the connecting sleeve 5 is in contact with the front surface of the connecting ring 4 .

[0019] Through the cooperation of the connecting ring 4 and the connecting sleeve 5, when the device is in use, one end of the silicone sleeve 3 can be passed through the center of the connecting ring 4 to make the silicone sleeve 3 form a circular ring shape, and the position of the connecting ring 4 on the surface of the silicone sleeve 3 can be adjusted according to the thickness of the patient's gastric tube. Then, the connecting sleeve 5 is installed to the position of the connecting ring 4 so that the connecting sleeve 5 blocks the connecting ring 4 to prevent the connecting ring 4 from sliding freely on the surface of the silicone sleeve 3, so that the connecting ring 4 can only be tightened inward, thereby preventing the silicone sleeve 3 from slipping off the surface of the gastric tube 1.

[0020] A movable groove 11 is provided on the other end surface of the silicone sleeve 3, and the output end of the push-pull electromagnet 7 is slidably inserted into the inside of the movable groove 11. The fixed sleeve 6 is fixedly installed with a protective end 8 near the position of the output end of the push-pull electromagnet 7. The output end of the push-pull electromagnet 7 and the other end of the silicone sleeve 3 are both movably inserted into the inside of the protective end 8.

[0021] The other end of the wire rope 10 is fixedly connected to the connecting rope 13, and the outer end of the connecting rope 13 is fixedly installed with a fixing ring sleeve 12. A plug rod 14 is fixedly installed inside the silicone sleeve 3 near the fixing ring sleeve 12, and the plug rod 14 is movably inserted into the center of the fixing ring sleeve 12.

[0022] A battery 15 is provided on the rear side of the fixing sleeve 6 , and the battery 15 is electrically connected to the push-pull electromagnet 7 .

[0023] The push-pull electromagnet 7 is continuously powered by the battery 15, thereby extending the service life of the push-pull electromagnet 7. When the battery 15 is low on power, the battery 15 can be directly replaced to extend the battery life of the push-pull electromagnet 7, avoiding the need to remove the device and then install a new one, thereby reducing the operations required by the doctor during surgery.

[0024] When using the magnetically controlled artificial esophageal sphincter, one end of the silicone sleeve 3 is first passed through the center of the connecting ring 4 to form the silicone sleeve 3 into a ring shape. The position of the connecting ring 4 on the surface of the silicone sleeve 3 can be adjusted according to the thickness of the patient's gastric tube. Then, the connecting sleeve 5 is installed to the position of the connecting ring 4 so that the connecting sleeve 5 blocks the connecting ring 4 to prevent the connecting ring 4 from sliding freely on the surface of the silicone sleeve 3. The connecting ring 4 can only be tightened inward, thereby preventing the silicone sleeve 3 from slipping off the surface of the gastric tube 1. Then, the output end is driven to be retracted and pushed outward by the push-pull electromagnet 7, so that the output end of the push-pull electromagnet 7 drives the wire rope 10 to move inside the movable groove 11, thereby controlling the tightening and anti-loosening of the silicone sleeve 3 to achieve the relaxation and contraction of the sphincter, thereby meeting the eating needs and avoiding the situation where the patient is unable to eat independently.
