Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a visual anti-reflux monitoring device for the digestive tract. Background Technology

[0002] Reflux of gastrointestinal contents is a significant factor contributing to numerous digestive system diseases. It is now clearly established that gastroesophageal reflux is closely related to the development of gastric and esophageal cancer; bile reflux is a major contributing factor to gastric cancer; and intestinal fluid reflux is a significant risk factor for pancreatitis and cholangitis. Some patients require surgery due to tumors or other reasons. The reconstructed digestive tract after surgical removal of gastric, esophageal, or duodenal cancer lacks natural anti-reflux sphincters, allowing digestive juices to reflux directly into the esophagus, stomach, bile duct, and pancreatic duct. Long-term reflux can lead to acute and chronic inflammation, and even neoplastic diseases, causing clinical symptoms such as esophagitis and heartburn, and increasing the risk of cancer in high-risk patients. Therefore, developing devices to prevent and control gastrointestinal reflux is an important means of preventing these related diseases.

[0003] Currently, the anti-reflux device and monitoring device for the digestive tract are used separately, requiring multiple digestive endoscopy examinations after the operation, which increases the patient's pain and cost, and the follow-up process for digestive tract diseases is cumbersome.

[0045] Example 1

[0046] One specific embodiment of the present invention, such as Figures 1 to 4 As shown, a visual anti-reflux monitoring device for the digestive tract lumen is disclosed, comprising:

[0047] Anti-reflux component 6, which can be fixed to the digestive tract and is configured to prevent the reflux of digestive juices;

[0048] The cavity section 1 is detachably connected to the anti-backflow assembly 6; the cavity section 1 has an internal cavity, and the top of the cavity section 1 is provided with a through hole 5 communicating with the cavity;

[0049] A body cavity monitoring component 3 is installed on the cavity portion 1 and is configured to monitor the condition inside the digestive tract cavity;

[0050] Guide wire 2, the first end of which is connected to the body cavity monitoring component 3; the guide wire 2 is installed in the cavity section 1 and can rotate within the through hole 5 and move along the center line of the through hole 5;

[0051] A drive assembly 8 is disposed in the cavity of the cavity section 1 and connected to the second end of the guide wire tube 2; the drive assembly 8 is connected to the body cavity monitoring assembly 3 through a transmission mechanism and is configured to adjust the monitoring angle and monitoring position of the body cavity monitoring assembly 3.

[0052] In this embodiment, the body cavity monitoring component 3 can be installed outside the cavity section 1; the body cavity monitoring component 3 can also be installed inside, extending out of the cavity section 1 during monitoring and retracting into the cavity section 1 when not monitoring or after monitoring is completed.

[0053] In one alternative implementation, such as Figures 2 to 3 As shown, the body cavity monitoring component 3 is disposed outside the cavity section 1, and the size of the body cavity monitoring component 3 is larger than the diameter of the through hole 5. The guide wire tube 2 is installed inside the through hole 5 of the cavity section 1, and the outer wall of the guide wire tube 2 is slidably connected to the hole wall of the through hole 5. The guide wire tube 2 can rotate around the center line of the guide wire tube 2 and move along the center line of the through hole 5 within the through hole 5.

[0054] In one alternative implementation, such as Figure 4 As shown, the body cavity monitoring component 3 is extendable and retractable inside the cavity portion 1. The body cavity monitoring component 3 can pass through the through hole 5 at the top of the cavity portion 1; the body cavity monitoring component 3 has a non-monitoring state and a monitoring state; in the non-monitoring state, the body cavity monitoring component 3 is located inside the cavity of the cavity portion 1; in the monitoring state, the body cavity monitoring component 3 is driven by the driving component 8 to extend out of the cavity of the cavity portion 1 through the through hole 5. By extending and retracting the body cavity monitoring component 3 inside the cavity portion 1, it can extend during monitoring and retract when not monitoring, avoiding dirt and ensuring the clarity of the monitoring field of view.

[0055] In this embodiment, the anti-reflux component 6 includes a deformable funnel 61, which can be mesh-like and ventilated. When the pressure below the digestive tract increases to a predetermined value, it can open upwards. For example, during vomiting, the back pressure is greater, so the deformable funnel 61 opens. When the pressure below the digestive tract is less, the deformable funnel 61 closes, thus playing a role in preventing the reflux of digestive juices under normal resting conditions.

[0056] In one optional embodiment, the deformable funnel 61 has a first end and a second end. The first end is an open end, and the surface from the first end to the second end is conical. Multiple split openings 63 are formed on the conical surface of the deformable funnel 61, extending and converging at the second end. By suturing and fixing the deformable funnel 61 to the digestive tract, with the wide opening and large diameter of the deformable funnel 61 facing upwards, food can smoothly enter the deformable funnel. Simultaneously, due to its deformability, the deformable funnel 61 can be easily opened through the split openings 63. After food passes through, the deformable funnel 61 can contract and recover, and the smaller cylindrical opening at the bottom can prevent the reflux of digestive juices, promoting patient recovery, reducing complications, and preventing the risk of cancer in high-risk patients caused by the reflux of digestive juices.

[0057] In this embodiment, a pinhole 62 is provided on the outer edge of the opening end of the deformable funnel 61, through which the deformable funnel 61 is fixed to the digestive tract. Furthermore, the deformable funnel 61 is detachably connected to the cavity 1 by a silk rope 7, that is, the cavity 1 is hung on the deformable funnel 61 by the silk rope 7.

[0058] In this embodiment, the deformable funnel part 61 has an elastic deformation function and can be made of materials such as polyester, polypropylene, polylactic acid, etc., or biomedical polymer materials such as polyether urethane, polytetrafluoroacetate, polyurethane, etc., or other types of materials, which need to meet medical requirements.

[0059] In one optional embodiment, the transmission mechanism includes a chain 15, a telescopic component 9, and two adjusting ropes 14. The drive component 8 is engaged with the chain 15, and its upper part is fixedly connected to the second end of the guide wire tube 2. The telescopic component 9 is fixedly connected to the lower side wall of the guide wire tube 2. The telescopic component 9 is configured to drive the guide wire tube 2 to reciprocate linearly along the centerline of the through hole 5, thereby adjusting the monitoring position of the body cavity monitoring component 3. Two adjusting ropes 14 are threaded inside the guide wire tube 2. The upper ends of the two adjusting ropes 14 extend out of the guide wire tube 2 and are fixedly connected to the body cavity monitoring component 3. The lower ends of the two adjusting ropes 14 are fixedly connected to the upper end of the chain 15. The monitoring angle of the body cavity monitoring component 3 is adjusted by pulling the two adjusting ropes 14 through the drive chain 15.

[0060] In this embodiment, a power supply 12 is fixedly installed inside the cavity of the cavity section 1. The power supply 12 is configured to provide power to the electrical components of the monitoring device. A transmitter 4 is fixedly installed on the cavity section 1. The transmitter 4 can send the received images to the image receiving system. A controller 11 is fixedly connected to the upper surface of the power supply 12.

[0061] In one alternative embodiment, a piezoelectric induction coil 10 is provided on the outer edge sidewall of the first end of the deformable funnel portion 61. The piezoelectric induction coil 10 is configured to convert pressure changes caused by peristalsis in the digestive tract into voltage to charge the power source 12. After implantation, the piezoelectric sensing coil 10 is located between the contact surface between the deformable funnel portion 61 and the digestive tract. It senses pressure changes caused by peristalsis in the digestive tract through the outer edge sidewall of the deformable funnel portion 61 and converts them into voltage to charge the power source 12. The piezoelectric induction coil 10 can meet the requirements of wireless charging, avoiding power outages of the power source 12.

[0062] In this embodiment, an anti-backflow component 6 is detachably connected to the outer side of the cavity section 1. A guide wire 2 slides upward through the cavity section 1. The first end of the guide wire 2 is fixedly connected to the body cavity monitoring component 3, and the first end of the guide wire 2 is a deformable end. Specifically, as shown... Figure 6 As shown, the body cavity monitoring assembly 3 includes a monitoring shell 33, which is transparent to ensure the monitoring probe 31 can perform monitoring operations. The deformable end of the guide wire tube 2 is connected to the monitoring shell 33. One side of the monitoring shell 33 is fixedly connected to two adjusting ropes 14. By pulling the two adjusting ropes 14, the monitoring shell 33 can be rotated to ensure the monitoring angle of the monitoring shell 33 can be adjusted. The monitoring shell 33 is connected to the wire 13. The monitoring probe 31 is fixedly installed inside the monitoring shell 33. Illumination lamps 32 are provided on both the upper and lower sides of the monitoring probe 31. The two illumination lamps 32 are fixedly installed in the monitoring shell 33 and can provide supplementary lighting to ensure that the monitoring probe 31 has a sufficient lighting monitoring environment.

[0063] like Figures 7 to 8 As shown, a wire 13 is connected to one side of the body cavity monitoring component 3. The wire 13 passes through the guide wire tube 2 and exits from the bottom of the guide wire tube 2 to connect with the power supply 12. The power supply 12 can store electricity and is built into the cavity section 1. A drive component 8 is provided on the upper surface of the power supply 12. The drive component 8 includes a first motor 81. A bracket 82 is fixedly connected to the bottom of the first motor 81 to fix the first motor 81 and maintain its stability. Two fixing strips 83 are fixedly connected to the bottom of the guide wire tube 2. The bracket 82 is fixedly installed on one of the fixing strips 83. A rotating shaft 84 is fixedly connected to the output shaft of the first motor 81. A sprocket 86 is fixedly connected to the outside of the rotating shaft 84. The sprocket 86 meshes with the chain 15, and the meshing of the sprocket 86 and the chain 15 drives the adjustment rope 14. The rotating shaft 84 is rotatably connected to two bearings 85. The bearings 85 can keep the rotating shaft 84 rotating smoothly. The two bearings 85 are respectively The bearing 85 is fixedly connected to two fixing bars 83, which can fix the bearing 85 and prevent it from falling off. The drive assembly 8 is engaged with the chain 15. The upper part of the drive assembly 8 is fixedly connected to the second end of the guide wire tube 2. The lower side wall of the guide wire tube 2 is fixedly connected to a telescopic assembly 9, which is fixedly installed on the power supply 12. The telescopic assembly 9 can drive the guide wire tube 2 to move back and forth linearly along the center line of the through hole 5, thereby adjusting the monitoring position of the body cavity monitoring assembly 3. Two adjusting ropes 14 are inserted inside the guide wire tube 2. Both adjusting ropes 14 are inserted through multiple guide sleeves 16. The guide sleeves 16 can guide the adjusting ropes 14 and keep them sliding smoothly. Multiple guide sleeves 16 are fixedly connected in the guide wire tube 2. The upper ends of the two adjusting ropes 14 pass out of the guide wire tube 2 and are fixedly connected to the body cavity monitoring assembly 3. The lower ends of the two adjusting ropes 14 are fixedly connected to the upper end of the chain 15, and the two adjusting ropes 14 are located on both sides of the wire 13.

[0064] The intraluminal visual anti-reflux monitoring device also includes an image receiving system that matches the transmitter 4. The image receiving system is set up independently, and the transmitter 4 is wirelessly connected to the image receiving system to collect transmitted images for clinical analysis.

[0065] By controlling the first motor 81 to drive the rotating shaft 84 to rotate, the rotating shaft 84 drives the sprocket 86 to rotate, causing the sprocket 86 to mesh with the chain 15, which in turn drives the adjusting rope 14 to move. This causes one adjusting rope 14 to loosen while the other tightens, which in turn pulls the monitoring shell 33 to move, causing the top of the guide wire tube 2 to turn, thus adjusting the angle. Similarly, controlling the first motor 81 to move in the opposite direction allows the monitoring shell 33 to drive the monitoring probe 31 to adjust the angle in the opposite direction. The telescopic component 9 drives the guide wire tube 2 to move back and forth linearly along the center line of the through hole, thereby adjusting the monitoring position of the body cavity monitoring component 3. This allows for adjustments to multiple monitoring angles and positions, facilitating clinical observation and analysis.

[0066] like Figure 5 As shown, the telescopic assembly 9 includes a second motor 91, which is fixedly mounted on the upper surface of the power supply 12. The output shaft of the second motor 91 is fixedly connected to a lead screw 92, and a nut 93 is threaded onto the outer side of the lead screw 92. A connecting strip 94 is fixedly connected to the outer side of the nut 93, and a connecting hole is located in the middle of the connecting strip 94. The nut 93 is fixedly installed in the connecting hole. The first side of the connecting strip 94 is fixedly connected to the guide tube 2, and the second side of the connecting strip 94 is fixedly connected to a movable sleeve 96. The movable sleeve 96 is slidably connected to the guide rod 95, which guides the movable sleeve 96 so that the movable sleeve 96 can slide smoothly up and down along the guide rod 95. This allows the nut 93 and the connecting strip 94 to move smoothly up and down. The guide rod 95 is fixedly connected to the upper surface of the power supply 12.

[0067] The controller 11 controls the second motor 91 to drive the lead screw 92 to rotate, which in turn drives the nut 93 to move. The nut 93 then drives the connecting bar 94 and the guide wire tube 2 to move upward, which in turn drives the monitoring housing 33 and the monitoring probe 31 to adjust upward. Similarly, the second motor 91 moves in the opposite direction, which allows the monitoring probe 31 to move downward. This allows for adjustment of the vertical position of the monitoring probe 31, enabling multi-position monitoring and observation, and facilitating clinical analysis.

[0068] In this embodiment, the power supply 12 is configured to provide power to the electrical components of the monitoring device. For example, the power supply 12 can supply power to the operation of electrical components such as the body cavity monitoring component 3, the transmitter 4, the controller 11, the first motor 81, and the second motor 91.

[0069] The working principle of this invention is as follows: During digestive tract reconstruction after surgical removal of the sphincter, a visual anti-reflux monitoring device is installed within the digestive tract lumen to achieve both prognostic monitoring and anti-reflux effects. Specifically, during surgery, the cavity monitoring component is first connected to the anti-reflux component. The deformable funnel portion 61 is sutured and fixed to the digestive tract through the pinhole 62, and the cavity monitoring component is suspended from the anti-reflux component. During observation, the controller 11 controls the first motor 81 to rotate the shaft 84, which in turn rotates the sprocket 86, causing the sprocket 86 to move the chain 15. This loosens one adjusting rope 14, while the other adjusting rope 14 pulls the monitoring shell 33, causing the monitoring shell 33 to rotate at the top of the guidewire tube 2, thus changing the monitoring angle of the monitoring probe 31. Simultaneously, the first motor 81 is controlled to reverse direction. When moving, the angle can be adjusted in another direction. Simultaneously, by controlling the operation of the second motor 91, the second motor 91 drives the lead screw 92, which in turn drives the nut 93 upward. The nut 93 then drives the connecting bar 94 upward, which in turn drives the guide wire tube 2 upward. This, in turn, drives the monitoring probe 31 upward. Similarly, when adjusting downward, simply control the second motor 91 to move in the opposite direction, allowing the monitoring probe 31 to move downward and adjust its monitoring position. This enables multi-angle and multi-position monitoring of the body cavity environment. After monitoring, the data can be transmitted to the image receiving system via the transmitter 4 for clinical analysis.

[0070] Compared with the prior art, the visual anti-reflux monitoring device for the digestive tract lumen provided in this embodiment can achieve at least one of the following beneficial effects:

[0071] 1. This invention is a miniature device with high-definition imaging capabilities. The body cavity monitoring component is connected to the anti-reflux component. After the anti-reflux component is sutured and fixed to the digestive tract, this invention achieves simultaneous monitoring and treatment of digestive tract diseases, reducing the need for postoperative stent implantation under digestive endoscopy, making it more convenient and avoiding cumbersome gastroscopy and colonoscopy examinations. It also enables rapid and efficient detection of cancer recurrence, while reducing the inconvenience and pain caused by conventional gastroscopy.

[0072] 2. The monitoring angle and position of the body cavity monitoring component are adjustable. Specifically, the guide wire is driven to move up and down by the telescopic component, which in turn drives the body cavity monitoring component to move, enabling it to monitor the patient's body cavity from multiple positions. Furthermore, the two adjustment ropes can be adjusted by the drive component engaging with the chain to adjust the angle of the body cavity monitoring component, thus enabling it to perform multi-directional detection of the patient's body cavity.

[0073] 3. By fixing the deformable funnel to the digestive tract with its wide opening and large diameter facing upwards, food can smoothly enter the deformable funnel. Due to its deformability, the funnel can be easily opened through the split opening. After food passes through, the funnel can contract and return to its original shape. The smaller cylindrical opening at the bottom prevents the reflux of digestive juices, promoting patient recovery, reducing complications, and mitigating the risk of cancer in high-risk patients due to digestive juice reflux.

[0074] 4. By setting a piezoelectric induction coil on the outer sidewall of the first end of the deformable funnel, after implantation, the piezoelectric sensing coil is located between the contact surface of the deformable funnel and the digestive tract. It converts the pressure changes of the digestive tract peristalsis into voltage, which can meet the needs of wireless charging and avoid power outages.

[0075] 5. By making the body cavity monitoring component extendable and retractable inside the cavity, it can extend during monitoring and retract when not monitoring, avoiding dirt and ensuring the clarity of the monitoring field of view.
