Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gastroesophageal sphincter control, in particular to a miniature motor control type artificial gastric tube sphincter. BACKGROUND

[0002] When food enters the esophagus, it stimulates the mechanical receptors on the esophageal wall, which reflexively causes the lower 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.

[0003] Patients with esophagogastric junction adenocarcinoma and other diseases related to the esophagus and stomach often cannot eat normally due to the effects of the disease, and need to use special liquid diet gastric tubes for assisted eating. The uneven nutrition of food brought about by this eating method cannot meet the nutritional needs of patients recovering from illness.

[0004] The existing special patients cannot simulate the relaxation and contraction of the normal eating sphincter during eating, which affects the recovery of the patients. Therefore, the existing needs are not met, and to solve this problem, we propose a miniature motor control type artificial gastric tube sphincter. UTILITY MODEL CONTENT

[0005] The utility model aims to provide a miniature motor control type artificial gastric tube sphincter to solve the problem of special patients being unable to simulate the relaxation and contraction of the normal eating sphincter during eating, which affects the recovery of the patients, as mentioned in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a miniature motor control type artificial gastric tube sphincter, comprising a gastric sac, the top end of the gastric sac is connected with a gastric tube, the outer surface of the gastric tube is movably installed with a bandage, the inside of the bandage is provided with a rope ring groove, the inside of the rope ring groove is movably installed with a tightening rope, the bandage is made of silica gel, the bandage is spirally wound on the surface of the gastric tube, and the tightening rope is attached to the surface of the gastric tube.

[0007] Preferably, both sides of the bandage are provided with flexible end portions, the surface of each flexible end portion is provided with a plurality of connecting holes, the outer surface of the bandage near the flexible end portion is fixedly installed with a fixed column, the outer surface of the fixed column is fixedly connected with a flexible belt, the end portion of the flexible belt is fixedly connected with a connecting plunger, and the two flexible end portions are connected with each other by inserting the two connecting plungers into the inside of the connecting holes, the connecting plungers are made of flexible material.

[0008] Preferably, each of the connecting plungers has a spring groove inside, and two limiting pins are slidably installed inside each of the spring grooves. A miniature spring is movably installed between each of the two limiting pins. Each of the connecting holes has a limiting groove inside, and the limiting pins are movably inserted into the limiting grooves.

[0009] Preferably, a protective shell is fixedly installed on the outer surface of both sides of the strap near the flexible end, and a push-pull electromagnet is fixedly installed inside the protective shell. The output end of the push-pull electromagnet is fixedly connected to a T-shaped connecting rod.

[0010] Preferably, both ends of the tightening rope are fixedly equipped with connectors, and the T-shaped connecting rods are movably inserted into the connectors.

[0011] Preferably, each of the protective shells has a battery on its outer side, and each battery is electrically connected to a push-pull electromagnet. The outer surface of the tightening rope is wrapped with a silicone tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the combination of a strap and flexible ends, allows the device to be used by spirally wrapping the strap around the surface of the gastric tube, then fitting the two flexible ends together, and overlapping some of the connecting holes according to the inner diameter of the gastric tube, thereby adjusting the inner diameter of the strap to accommodate people with different gastric tube sizes. Furthermore, the two flexible ends are connected by inserting a connecting plunger into the connecting hole, thus preventing the flexible ends from falling off each other.

[0014] 2. This utility model, through the cooperation of a tightening rope and a push-pull electromagnet, allows the device to be used by remotely controlling the push-pull electromagnet to drive the T-shaped connecting rod to retract. This, in turn, pulls both ends of the tightening rope through the connector, causing the tightening rope to tighten inward, thereby squeezing the gastric tube inward. Subsequently, the push-pull electromagnet drives the T-shaped connecting rod to push out, causing the tightening rope to loosen, and thus the gastric tube to relax, achieving the relaxation and contraction of the sphincter, thereby satisfying the need for eating.

[0015] 3. This utility model utilizes the combination of limiting pins and miniature springs. When the connecting plunger is inserted into the connecting hole, the two limiting pins on the surface of the connecting plunger can be pressed to retract into the spring grooves. Then, the plunger is inserted into the connecting hole. At this time, the limiting pins will be ejected by the elastic potential energy of the miniature springs and locked into the limiting grooves, thereby fixing the two flexible ends. When the device needs to be removed, since it is a disposable item, it can be removed simply by cutting the strap. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4 One embodiment of this utility model is a micro motor-controlled artificial gastric sphincter, including a gastric pouch 2, with a gastric tube 1 connected to the top of the gastric pouch 2. A strap 3 is movably installed on the outer surface of the gastric tube 1. The strap 3 has a rope loop groove 9 inside, and a tightening rope 10 is movably installed inside the rope loop groove 9. The strap 3 is made of silicone and is spirally wound around the surface of the gastric tube 1. The tightening rope 10 is in contact with the surface of the gastric tube 1.

[0024] By cooperating with the tightening rope 10 and the push-pull electromagnet 11, the device can be used in a way that allows the push-pull electromagnet 11 to drive the T-shaped connecting rod 13 to retract via an external remote control. This, in turn, pulls both ends of the tightening rope 10 through the connector 12, causing the tightening rope 10 to tighten inward. This, in turn, compresses the gastric tube 1 to contract inward. Subsequently, the push-pull electromagnet 11 drives the T-shaped connecting rod 13 to extend, causing the tightening rope 10 to relax and the gastric tube 1 to relax. This achieves the relaxation and contraction of the sphincter muscles, thereby satisfying the need for eating.

[0025] Both ends of the strap 3 are provided with flexible ends 5. The surface of each flexible end 5 is provided with multiple connecting holes 7. A fixing post 19 is fixedly installed on the outer surface of the strap 3 near the flexible end 5. A flexible strip 14 is fixedly connected to the outer surface of the fixing post 19. A connecting plunger 8 is fixedly connected to the end of each flexible strip 14. The two flexible ends 5 are connected to each other by two connecting plungers 8 inserted into the connecting holes 7. The connecting plungers 8 are all made of flexible material.

[0026] By combining the strap 3 and the flexible end 5, the device can be used by spirally wrapping the strap 3 around the surface of the gastric tube 1, then fitting the two flexible ends 5 together, and overlapping some of the connecting holes 7 according to the inner diameter of the gastric tube 1, thereby adjusting the inner diameter of the strap 3 to accommodate users with different gastric tube 1 sizes. The two flexible ends 5 are connected by inserting the connecting plunger 8 into the connecting hole 7, thus preventing the flexible ends 5 from falling off each other.

[0027] Each connecting plunger 8 has a spring groove 15 inside, and two limit pins 16 are slidably installed inside each spring groove 15. A miniature spring 17 is movably installed between the two limit pins 16. Each connecting hole 7 has a limit groove 18 inside, and the limit pins 16 are movably inserted into the limit groove 18.

[0028] With the cooperation of the limiting pins 16 and the miniature springs 17, when the device is in use, before the connecting plunger 8 is inserted into the connecting hole 7, the two limiting pins 16 on the surface of the connecting plunger 8 can be pressed to retract the limiting pins 16 into the spring grooves 15. Then, it is inserted into the connecting hole 7. At this time, the limiting pins 16 will be ejected by the elastic potential energy of the miniature springs 17 and locked into the limiting grooves 18, thereby fixing the two flexible ends 5. When the device needs to be removed, since the device is a disposable item, it can be removed simply by cutting the straps 3.

[0029] Protective housings 4 are fixedly installed on the outer surfaces of both sides of the strap 3 near the flexible end 5. Push-pull electromagnets 11 are fixedly installed inside the protective housings 4. T-shaped connecting rods 13 are fixedly connected to the output ends of the push-pull electromagnets 11.

[0030] Both ends of the tightening rope 10 are fixedly installed with connectors 12, and the T-shaped connecting rods 13 are movably inserted into the connectors 12.

[0031] The outer side of the protective shell 4 is equipped with batteries 6, which are electrically connected to the push-pull electromagnet 11. The outer surface of the tightening rope 10 is wrapped with a silicone tube.

[0032] When using this micro-motor controlled artificial gastric tube sphincter, the strap 3 is first spirally wrapped around the surface of the gastric tube 1, then the two flexible ends 5 are attached to each other, and the connecting holes 7 are partially overlapped according to the inner diameter of the gastric tube 1, thereby adjusting the inner diameter of the strap 3 to accommodate people with different gastric tube 1 sizes. The two flexible ends 5 are connected by inserting the connecting plunger 8 into the connecting hole 7, thereby preventing the flexible ends 5 from falling off each other.

[0033] Before the connecting plunger 8 is inserted into the connecting hole 7, the two limiting pins 16 on the surface of the connecting plunger 8 can be pressed to retract the limiting pins 16 into the spring groove 15. Then, it is inserted into the connecting hole 7. At this time, the limiting pins 16 will be ejected by the elastic potential energy of the micro spring 17 and stuck into the limiting groove 18, thereby fixing the two flexible ends 5.

[0034] When a person needs to eat, the push-pull electromagnet 11 can be remotely controlled to drive the T-shaped connecting rod 13 to retract, thereby pulling the two ends of the tightening rope 10 through the connector 12, causing the tightening rope 10 to tighten inward, which in turn squeezes the gastric tube 1 to contract inward. Then, the push-pull electromagnet 11 drives the T-shaped connecting rod 13 to push out, causing the tightening rope 10 to relax, which in turn relaxes the gastric tube 1, realizing the relaxation and contraction of the sphincter, thereby satisfying the need to eat.

[0035] When it is necessary to remove the device, since the device is a disposable item, it can be removed simply by cutting the strap 3.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
