Description

Technical Field

[0001] This invention relates to the field of intestinal microendoscopy technology, specifically to a targeted recognition intelligent release device for intestinal microendoscopy. Background Technology

[0002] Intestinal diseases, such as inflammatory bowel disease, intestinal tumors, polyps and ulcers, are common and frequently occurring diseases in clinical practice. Currently, the intraluminal local drug treatment for these diseases mainly relies on drug spraying or irrigation under the assistance of traditional electronic colonoscopy. However, this conventional mode has several inherent defects, which seriously restrict its therapeutic effect and application prospects. A Chinese patent with publication number CN118987451A discloses a drug delivery tube inserted through the working channel of a colonoscope. This drug delivery tube can avoid backflow of body fluids caused by changes in internal pressure. However, this device, as well as traditional drug delivery devices, cannot achieve precise operation during drug delivery and still has some problems: First, the drug has poor targeting and limited efficacy. In traditional colonoscopy, after the drug is delivered and sprayed to the target area through the working channel, it is quickly diluted by the fluid in the intestine and carried away by the continuous peristalsis of the intestine. It is impossible to maintain an effective drug concentration and sufficient time of action at the lesion site. This directly leads to low drug utilization and unsatisfactory treatment effect, especially for deep or refractory lesions, where the effect is often minimal. Secondly, the treatment process lacks quantitative assessment methods. Existing technology relies entirely on doctors' subjective visual judgment to assess the size and severity of the lesion, as well as the recovery after treatment. This qualitative rather than quantitative assessment method lacks objective data support, has significant individual differences, and makes it difficult to make accurate and consistent judgments and records of disease progression and treatment effects. Furthermore, existing equipment has limited functionality and low intelligence. Traditional colonoscopy systems primarily function as observation and biopsy sites, with only basic drug delivery capabilities. They cannot achieve precise drug dosage and controllable release, nor do they possess the ability to create localized isolation treatment areas in complex intracavitary environments. The entire treatment process is highly dependent on the operator's experience and lacks automated feedback and control systems.

[0003] Therefore, there is an urgent need in this field for a new type of intestinal interventional device that can integrate precise observation, quantitative assessment, local occlusion and intelligent drug delivery to solve many technical bottlenecks in existing technologies, such as insufficient drug efficacy, subjective assessment and reliance on experience in operation.

[0007] Furthermore, the water tank is filled with a high-viscosity liquid, and the interior of the water tank is connected to the inlet pipe via a liquid extraction pipe and a micro-flow pump. The micro-flow pump is electrically connected to a control module, which is used to control the start and stop of the micro-flow pump.

[0008] Furthermore, the input end of the peristaltic pump is fixedly connected to a drug-drawing tube, and the other end of the drug-drawing tube is provided with a syringe for filling with liquid medicine. The output end of the peristaltic pump is fixedly connected to a drug-delivery tube. The upper surface of the top plate is fixedly connected to a solenoid valve. The input end of the solenoid valve is fixedly connected to one end of the drug-delivery tube, and the output end of the solenoid valve is fixedly connected to a drug-inlet tube. The other end of the drug-inlet tube extends into the interior of the wrapping layer.

[0009] Furthermore, the drug inlet tube is connected to the inside of the syringe through the paths of the solenoid valve, the drug delivery tube, the peristaltic pump, and the drug extraction tube. The peristaltic pump and the solenoid valve are both electrically connected to the control module, which is used to control the start and stop of the solenoid valve and the peristaltic pump.

[0010] Furthermore, the observation mechanism also includes a fiber optic controller. The lower side of the fiber optic controller is fixedly connected to the upper surface of the top plate. An optical fiber is provided at the output end of the fiber optic controller. The other end of the optical fiber extends into the interior of the wrapping layer. The outer wall of the wrapping layer away from the fiber optic controller is fixedly connected to the inner wall of the magnetic ring. A fixing layer is fixedly connected to the inner wall of the wrapping layer located inside the magnetic ring. The inner wall of the fixing layer is fixedly connected to the outer wall of the solenoid valve. A telescopic mechanism is provided inside the fixing layer. A connecting sleeve is fixedly connected to the inner wall of the fixing layer. A fixed-focus camera is fixedly connected to the inner wall of the connecting sleeve. The outer wall of the connecting sleeve is fixedly connected to the outer wall of the optical fiber.

[0011] Furthermore, the magnetic ring is a strongly magnetic structure, the outer wall of the wrapping layer is a rubber structure, the fixing layer is a rubber structure, two optical fibers are provided, and a reference target is provided on the inner wall of the disinfection tank in front of the fixed-focus camera.

[0012] Furthermore, the fixed layer has a hole with a groove on its inner wall, one side of the hole is connected to one end of the liquid inlet pipe, and the outer wall of the liquid inlet pipe is fixedly connected to the inner wall of the hole.

[0013] Furthermore, the telescopic mechanism includes a sliding tube located inside a hole in the fixed layer. A limit buckle is provided on the outer wall of the sliding tube located inside the hole. The limit buckle is located in a groove on the inner wall of the hole. An elastic membrane is fixedly connected to the outer wall of the end of the sliding tube away from the liquid inlet pipe.

[0014] Furthermore, the elastic membrane is made of rubber, the sliding tube can slide relative to the fixed layer, and the interior of the sliding tube is connected to the interior of the liquid inlet tube through holes.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention combines a flexible, in-body wrapping layer with a fixed-focus camera and an illumination fiber integrated at its front end, which can enter the intestine without damage and transmit intracavitary images to an external display in real time. The internal fixing layer and connecting sleeve provide rigid support for the fixed-focus camera, effectively avoiding image jitter caused by bending and twisting of the flexible tube, thereby providing the operator with a clear and stable field of view and laying a solid foundation for accurately locating the lesion area.

[0016] Through a drug delivery mechanism controlled by a peristaltic pump and a solenoid valve, this equipment can deliver liquid medicine through a drug inlet tube inside the wrapping layer to the front end and spray it out. Since the drug outlet is located to the side of the fixed-focus camera's field of view, precise targeted spraying is achieved. The solenoid valve's cut-off function during non-spraying phases overcomes the problem of liquid medicine leakage due to gravity or residual pressure, ensuring the accuracy of the dosage and the safety of operation.

[0017] By using a sealing mechanism formed by a sliding tube driven by a micro-flow pump and an elastic membrane, this device can actively construct a temporary closed treatment chamber around the lesion area in the intestine. This design confines the drug within the chamber, allowing it to have prolonged and high-concentration contact with the lesion tissue. This effectively solves the problem of drug dilution or rapid flushing away by intestinal contents in traditional methods, thereby significantly improving drug utilization and treatment efficacy.

[0018] This invention establishes a pixel-to-physical-size conversion relationship at a fixed object distance by pre-calibrating a reference object of known size in an in vitro sterilization tank. This provides objective data support for disease diagnosis and efficacy assessment. At the same time, it effectively suppresses the main measurement errors caused by inconsistent imaging distances by standardizing the operating procedures. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figure 1-6 The present invention provides a technical solution: the encapsulation layer 903 is made of a flexible, biocompatible medical polymer material, which constitutes the main channel for the device to enter the body. The distal end of the encapsulation layer 903 is fixed with a more rigid fixing layer 905 by adhesive bonding. The fixed fixing layer 905 is fixedly installed with a fixed focus camera 908 at the center of the fixing layer 905 by a connecting sleeve 907. The connecting sleeve 907 ensures the stability of the camera's optical axis. The optical fiber 902 is a bundle of several thin optical fibers. Its proximal end is connected to the optical output port of the optical fiber controller 901, and its distal end passes through the channel reserved inside the encapsulation layer 903 and is finally precisely laid on the front end of the fixing layer 905. Its light output direction is pointed in front of the field of view of the fixed focus camera 908 to provide sufficient and uniform illumination. The data line of the fixed focus camera 908 also passes through the encapsulation layer 903 and is finally connected to the image processing unit of the control module 6. During use, the operator holds the proximal end of the wrapping layer 903 and slowly inserts it into the patient's intestine. After the system is activated, the fiber optic controller 901 emits light, which is transmitted through the fiber optic cable 902 to the inside of the intestine, illuminating the tissue in front. At the same time, the fixed-focus camera 908 starts working, capturing real-time video signals of the illuminated intestinal wall and transmitting them to the control module 6 via a data cable. After processing, the signals are displayed on an external monitor. Based on this real-time image, the operator manually adjusts the depth and angle of the wrapping layer 903 to achieve a systematic examination of the intestinal wall and ultimately locates the center of the field of view on the lesion area that needs treatment.

[0022] Example 2: Please see Figure 1-6Based on Embodiment 1, the present invention provides a technical solution: the drug supply mechanism 8 includes a syringe 803, which serves as a drug container and is detachably placed on the top plate 2 of the trolley. One end of the drug extraction tube 802 is inserted into the bottle mouth of the syringe 803 and extends into the bottom of the drug solution. The other end is in fluid communication with the inlet end of the peristaltic pump 801 fixedly installed on the top plate 2. The outlet end of the peristaltic pump 801 is connected to the inlet end of the solenoid valve 805, which is also fixed on the top plate 2, through the drug delivery tube 804. The outlet end of the solenoid valve 805 is connected to the proximal end of the drug inlet tube 806. The drug inlet tube 806 is a slender flexible microtube. After being led out from the solenoid valve 805, it passes through the interior of the wrapping layer 903 and extends along its length. Finally, its distal outlet passes through the fixed layer 905 and opens to the side of the fixed-focus camera 908. After the wound is located and identified through Example 1, the operator starts the spraying program through the control module 6. The control module 6 first sends a command to the solenoid valve 805 to open it, and then drives the peristaltic pump 801 to work. The peristaltic pump 801 draws out the medicine from the syringe 803 in a metered amount, and pumps it into the inlet tube 806 through the delivery tube 804 and the opened solenoid valve 805. The medicine is finally sprayed out from the outlet at the front end of the inlet tube 806. Since the outlet angle is in the same direction as the screen, the medicine can be accurately sprayed on the wound surface observed in real time by the fixed-focus camera 908. After the preset dose is delivered, the control module 6 closes the peristaltic pump 801 and the solenoid valve 805. The latter can effectively prevent the medicine from dripping under the residual pressure in the pipeline.

[0023] Example 3: Please see Figure 1-8 Based on Embodiments 1 and 2, the present invention provides a technical solution: the sealing mechanism 7 includes a water tank 703, which is fixed to the lower layer of the trolley 1 and contains a high-viscosity sterile liquid, such as a mixture of glycerol and physiological saline. The proximal end of the suction tube 702 extends into the bottom of the water tank 703, and the distal end is connected to the inlet of a micro-flow pump 701 fixedly installed on the top plate 2. The outlet of the micro-flow pump 701 is connected to the proximal end of an inlet tube 704, and the distal end of the inlet tube 704 penetrates the wrapping layer 903. It leads to a hole with a groove on the fixed layer 905. The sliding tube 601 is slidably nested in this hole. Its outer wall is provided with a limiting buckle 603 that cooperates with the groove to prevent it from rotating or completely falling out. The elastic membrane 602 is made of elastic medical silicone. Its edge is airtightly fixed to the distal opening of the sliding tube 601 by medical-grade adhesive or vulcanization process. Thus, the liquid inlet tube 704 and the sliding tube 601 and elastic membrane 602 in the telescopic mechanism 906 together constitute a closed hydraulic actuation system. After initial spraying using Example 2, or for areas requiring deeper treatment, this function can be activated. The operator starts the micro-flow pump 701 via control module 6. This pump pumps the high-viscosity liquid in water tank 703 into the cavity of sliding tube 601 through suction pipe 702 and inlet pipe 704. The continuous injection of liquid generates pressure, which on the one hand pushes the sliding tube 601 to overcome friction and extend smoothly forward along the groove, and on the other hand causes the elastic membrane 602 fixed to the front end of the sliding tube 601 to expand elastically, forming a spherical structure. At this time, the operator gently pushes the entire device so that the expanded elastic membrane 602 is in contact with the lower side of the wound. The intestinal wall is tightly sealed around the periphery. This process is carried out under the real-time monitoring of the fixed-focus camera 908 to ensure that the intestine below the wound is blocked by the expanded elastic membrane 602. Then, in this sealed state, the drug delivery mechanism 8 is activated again to release the drug into the cavity formed on the upper side of the elastic membrane 602. The drug is confined in the cavity and has a long-term, high-concentration contact with the wound, which significantly improves the treatment effect. After the treatment, the control module 6 reverses the micro-flow pump 701 to draw the liquid back. The elastic membrane 602 contracts under its own elastic recoil and external intestinal wall pressure, and the sliding tube 601 resets accordingly, so the device can be safely removed.

[0024] Example 4: Please see Figure 1-8 Based on Embodiments 1, 2 and 3, the present invention provides a technical solution: This embodiment aims to provide a method for estimating the area of ​​intestinal wounds in vivo, which overcomes the difficulty of using physical targets in vivo through pre-calibration and optical principles; Before using the equipment, the front end of the observation mechanism 9, namely the fixed layer 905 and the fixed-focus camera 908, is placed into the disinfection tank 3. On the inner wall of the disinfection tank 3, there is a reference target 909 with known physical dimensions. The operator fixes the front end of the equipment at a specific calibration position through the control module 6, so that the reference target 909 is clearly imaged in the field of view of the fixed-focus camera 908. At this time, the image processing unit of the control module 6 will perform the following operations: Identify the reference object, calculate the number of pixels it occupies in the image, and calculate the pixel-to-size conversion factor at the current fixed calibration distance based on its known physical size; This coefficient represents the actual physical size of each pixel in the image at a specific object distance. Since the camera is a fixed-focus lens, this calibration value has a strict, one-to-one correspondence with the object distance. Once the device enters the body and detects the wound, the operator manipulates the device to fill the field of view as much as possible and create a clear image of the wound. At this point, the system estimates the area based on the following principle: The fixed-focus camera 908 has a fixed focal length and depth of field range. In order to make accurate area comparisons, the operating procedure requires the operator to adjust the camera to a distance from the wound surface that is approximately equal to the object distance at the pre-calibration time, that is, to put the wound surface within the lens's optimal focus range. This ensures that the magnification of the image is as consistent as possible with the calibration time. Under the premise of meeting the above focusing requirements, the system defaults to the current imaging magnification being approximately the same as that during calibration. The image processing unit then performs the following steps: identifying and segmenting the wound area in the image, calculating the total pixel area occupied by the wound area, and estimating the actual physical area of ​​the wound using the pre-calibrated and stored conversion coefficients. This method utilizes the characteristic that the magnification of a fixed-focus lens remains essentially unchanged at a fixed object distance, providing the operator with a fast and quantitative area estimation tool. Furthermore, the detection mechanism 5 can be removed from the placement plate 4 and placed on the patient's abdomen. The operator holds the handle 503, allowing the mounting shell 501 to cover the upper side of the patient's abdomen. The magnetic array 502 is used to locate the magnetic ring 904 to assist in determining the displacement distance, thereby assisting in determining the size of the wound.
