Description

Technical Field

[0001] This invention belongs to the field of fecal microbiota transplantation technology, specifically an implantation combination device for fecal microbiota transplantation in the lower digestive tract of shrimp. Background Technology

[0002] Fecal microbiota transplantation (FMT) is a treatment method that transplants the gut microbiota of a healthy donor into the gut of a patient to restore or regulate the balance of the gut microbiota. In shrimp, artificially transplanting the gut microbiota or specific functional microbiota of healthy shrimp into diseased or imbalanced shrimp can be used for disease control in specific stages, such as in broodstock shrimp. Conversely, artificially transplanting the gut microbiota or specific functional microbiota of diseased or imbalanced shrimp into healthy shrimp can be used in scientific research on aquatic diseases and feed. FMT can also enhance the shrimp's immunity, improve disease resistance, and growth performance by regulating the gut microbial environment, thereby reducing antibiotic use. However, the shrimp's digestive tract is very small (especially the lower digestive tract), requiring extremely fine transplantation tools to precisely inject the bacterial solution into the target location. Furthermore, the shrimp struggles and bends violently during the transplantation process, which can easily lead to intestinal tissue damage. Therefore, the requirements for non-invasive control of the implantation device and the live shrimp are very high. Currently, transplantation is mostly performed manually using syringes. However, manual operation requires high technical skills from the operator, and it is difficult to control the shrimp body without causing damage. The injection position and depth are also difficult to control precisely, which can easily cause damage to the shrimp body or injection failure.

[0003] The prior art document, CN221867070U, discloses an upper gastrointestinal nasojejunal tube implantation assembly for fecal microbiota transplantation, belonging to the field of fecal microbiota transplantation. It comprises a warming and uniform injection device, an L-shaped connecting tube, a detachable connecting mechanism, a sealing mechanism, a retractable and flexible deformable tube, a transparent flexible tube, and a perforated threaded tube. In this solution, the L-shaped connecting tube is used to deliver the fecal microbiota solution discharged from the warming and uniform injection device. The retractable and flexible deformable tube allows for extension and bending, facilitating insertion of the external threaded connecting tube into the nasal cavity and intestines. It can be adjusted according to the curvature of the nasal cavity and intestines, ensuring a safe and comfortable user experience. The perforated threaded tube has multiple micropores, enabling uniform delivery of fecal microbiota without the risk of the microbiota solution clogging the tube. This solves the problems of discomfort and strong odor associated with nasojejunal tube placement on the patient's face when using a syringe for nasojejunal tube injection in existing technologies.

[0004] While the aforementioned patents achieve the goal of comfort and uniform delivery of fecal microbiota transplantation in the human upper digestive tract, they cannot effectively solve the special problems encountered in the live transplantation process of small aquatic organisms such as shrimp. The device lacks a structure for fixing and holding live shrimp, positioning the shrimp tail, and guiding the injection angle. It cannot achieve precise injection while the shrimp is struggling, which can easily cause injection position deviation or intestinal damage. Although traditional manual injection methods can be operated with difficulty, they have problems such as high operation difficulty, low success rate, and easy damage to the shrimp. They are difficult to meet the needs of disease prevention and control in large-scale and precise aquaculture. Therefore, there is a need for a transplantation device that can achieve stable holding of live shrimp, precise positioning of the shrimp tail, automatic guidance of the injection process, and simple and efficient operation. Summary of the Invention

[0005] The purpose of this invention is to provide an automated and precise implantation device for fecal microbiota transplantation in the lower digestive tract of shrimp, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an implantation assembly for fecal microbiota transplantation in the lower digestive tract of shrimp, comprising a vertical plate, a U-shaped frame fixedly connected to the side wall of the vertical plate, a cylinder fixedly connected to the middle of the U-shaped frame, an injection module penetratingly connected to the bottom of the U-shaped frame, the injection module being fixedly connected to a liquid tank via an air pump, the liquid tank being detachably connected to the vertical plate, and further comprising:

[0007] A live shrimp gripping mechanism, wherein the live shrimp gripping mechanism is located on a vertical plate;

[0008] An auxiliary injection mechanism, which is connected to a live shrimp holding mechanism;

[0009] The live shrimp clamping mechanism includes a tapered plate fixed to the middle of the vertical plate, a slot in the middle of the tapered plate, an arc-shaped base plate above the tapered plate and fixed to the vertical plate, and an injection hole on the side of the U-shaped frame near the vertical plate.

[0010] Preferably, the live shrimp clamping mechanism further includes a cylinder fixed to the outside of the U-shaped frame. The output end of the cylinder passes through the U-shaped frame and is fixed to a push plate. The lower side of the push plate is provided with an arc segment, and the inner diameter of the arc segment is adapted to the size of the tapered plate. Both the upper and lower ends of the push plate are slidably connected to the inner side of the push plate.

[0011] Preferably, a light shield is fixed to the top of the push plate, and a pair of arc-shaped plates are rotatably connected to the middle of the push plate.

[0012] Preferably, the outer walls of the arc-shaped plates are elastically connected to the push plates, and the curvature of the arc-shaped plates is less than the curvature of the arc-shaped substrate.

[0013] Preferably, a silicone airbag is fixedly connected to the middle of the push plate. The silicone airbag is located between a pair of arc-shaped plates, and an air inlet pipe is fixedly connected to the middle of the silicone airbag. The outer wall of the air inlet pipe penetrates and extends to the outside of the push plate.

[0014] Preferably, the auxiliary injection mechanism includes a slide groove formed on the lower side of the U-shaped frame, slide bars are fixedly connected to both sides of the bottom of the push plate, and a first magnetic block is fixedly connected to the end of each slide bar. The slide bars and the first magnetic blocks are slidably connected in the slide groove.

[0015] Preferably, the lower side of the vertical plate is provided with an arc-shaped groove, the bottom of the U-shaped frame is rotatably connected to a hollow guide plate, the width of the hollow guide plate is smaller than the width of the arc-shaped groove, and the top of the hollow guide plate is provided with a V-shaped groove.

[0016] Preferably, gears are fixed to both sides of the hollow guide plate, and racks mesh with the outer walls of the gears.

[0017] Preferably, a second magnetic block is fixed to each side of the rack near the first magnetic block, and the second magnetic block and the first magnetic block are magnetically attracted to each other.

[0018] Preferably, the top of the injection module is fixed with an extension needle and an ultra-fine soft rubber needle, and the two slide through the injection hole.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This invention achieves adaptive light-blocking clamping of shrimp by setting up a push plate, an arc plate, a silicone airbag and a light shield. The light shield fixed to the top of the push plate moves forward synchronously during the clamping process, effectively blocking external light and reducing the stress response of shrimp caused by strong light. At the same time, the arc plate elastically adapts to the contour of the shrimp's back, and the silicone airbag inflates between a pair of arc plates, adjusting the flexible squeezing force according to the shrimp's struggle. Compared with the existing rigid clamping method, this invention not only ensures stable clamping of the shrimp but also avoids injury to the tissue, significantly improving the clamping safety during the injection of live shrimp.

[0021] (2) This invention achieves precise positioning and minimally invasive injection of shrimp tail by setting up a tapered plate, a groove, an arc-shaped groove and an injection module. The tapered plate is narrow at the bottom and wide at the top. The groove in the middle allows the shrimp tail to pass through laterally. Utilizing the inertia of the shrimp's backward movement, the shrimp tail is gradually guided to the narrow opening of the tapered plate. The closer it goes, the tighter it fits, thus achieving initial positioning of the shrimp tail. The arc-shaped groove further aligns the opening of the shrimp's lower digestive tract with the injection hole. With the help of an ultra-fine soft rubber needle, it is slowly inserted along the direction of the hollow guide plate. During the insertion process, it automatically follows the direction of the intestine and avoids piercing the intestinal wall. Compared with the manual injection method, it achieves precise and minimally invasive automated injection.

[0022] (3) By setting up a push plate, a first magnetic block, a second magnetic block, a hollow guide plate and an arc-edge groove, the present invention achieves the synchronous linkage of clamping action and tail guiding action without power, and can adapt to different shrimp sizes. When the push plate moves forward, the first magnetic block drives the second magnetic block to move through magnetic attraction, driving the rack and gear to make the hollow guide plate flip upward. The V-shaped groove at the top of the plate gradually squeezes the shrimp tail scales and presses the shrimp tail into the arc-edge groove. When the shrimp is small, the push plate needs to be closer to the vertical plate to clamp the shrimp body. The flip angle of the hollow guide plate increases accordingly, further pressing the shrimp tail into the arc-edge groove to make up for the distance difference. This ensures the accuracy of injection positioning for shrimp of different sizes and avoids damage caused by excessive squeezing. Attached Figure Description

Detailed Implementation

[0034] 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.

[0035] like Figures 1 to 9 As shown, this invention provides an implantation assembly for fecal microbiota transplantation in the lower digestive tract of shrimp, including a vertical plate 100, a U-shaped frame 200 fixedly connected to the side wall of the vertical plate 100, a cylinder 400 fixedly connected to the middle of the U-shaped frame 200, an injection module 300 penetratingly connected to the bottom of the U-shaped frame 200, and a liquid tank 800 fixedly connected to the injection module 300 via an air pump 700. The liquid tank 800 is detachably connected to the vertical plate 100, and also includes:

[0036] The live shrimp clamping mechanism 500 is located on the vertical plate 100;

[0037] An auxiliary injection mechanism 600 is connected to a live shrimp holding mechanism 500.

[0038] The live shrimp clamping mechanism 500 includes a tapered plate 540 fixed to the middle of the vertical plate 100, a slot 590 is provided in the middle of the tapered plate 540, an arc-shaped base plate 550 is provided above the tapered plate 540 and the arc-shaped base plate 550 is fixed to the vertical plate 100, and an injection hole 560 is provided on the side of the U-shaped frame 200 near the vertical plate 100.

[0039] The above-mentioned solution involves bolting the injection module 300, air pump 700, and liquid tank 800 to the vertical plate 100 for easy removal, maintenance, and replacement. The injection head of the injection module 300 can be removed and autoclaved without affecting other fecal microbiota transplantation. The injection module 300 mainly consists of a tubing, a pressure column, an extension needle, an ultra-fine soft rubber needle, and a drive unit. The ultra-fine soft rubber needle has a ring of micro-holes at its tip, allowing the bacterial solution to be evenly sprayed onto the intestinal wall during injection, facilitating bacterial colonization. The system can automatically inject the fecal microbiota liquid into the tubing. The air pump 700 and liquid tank 800 are interconnected. The liquid tank 800 contains an automatic stirring rod and a filter, which, in conjunction with the air pump 700, can quantitatively extract or push in appropriate liquid, with a minimum injection dose of 50 microliters. This allows for both automatic quantitative injection of the bacterial solution and replacement of empty injection solutions, as well as appropriate aspiration of intestinal fluid for cleaning. All of the above are existing technologies and will not be elaborated upon further. The vertical plate 100 serves as the main support, with a U-shaped frame 200 fixed to its side wall, providing a base for the installation of the cylinder 400. The cylinder 400 is located in the middle of the U-shaped frame 200 and drives the operation of the live shrimp clamping mechanism 500. The live shrimp clamping mechanism 500 includes a tapered plate 540 fixed to the middle of the vertical plate 100, with a slot 590 providing a channel for the live shrimp to enter. Above the tapered plate 540, an arc-shaped base plate 550 is also fixed to the vertical plate 100, forming a clamping cavity together with the tapered plate 540 to securely clamp the live shrimp to be transplanted. Simultaneously, an injection hole 560 is provided on the side of the U-shaped frame 200 near the vertical plate 100. This injection hole 560 is connected to the auxiliary injection mechanism 600, enabling precise injection into the lower digestive tract of the shrimp after the live shrimp clamping mechanism 500 has completed clamping.

[0040] like Figures 2 to 7 As shown, the live shrimp gripping mechanism 500 also includes a cylinder 400 fixed to the outside of the U-shaped frame 200. The output end of the cylinder 400 passes through the U-shaped frame 200 and is fixedly connected to a push plate 510. The lower side of the push plate 510 is provided with an arc segment, and the inner diameter of the arc segment is adapted to the size of the tapered plate 540. Both the upper and lower ends of the push plate 510 are slidably connected to the inner side of the push plate 510. A light shield 530 is fixedly connected to the top of the push plate 510. A pair of arc-shaped plates 520 are rotatably connected to the push plate 510; the outer walls of the arc-shaped plates 520 are elastically connected to each other, and the curvature of the arc-shaped plates 520 is less than the curvature of the arc-shaped base plate 550; a silicone airbag 570 is fixedly connected to the middle of the push plate 510, the silicone airbag 570 is located between the pair of arc-shaped plates 520, and an air inlet pipe 580 is fixedly connected to the middle of the silicone airbag 570, the outer wall of the air inlet pipe 580 penetrates and extends to the outside of the push plate 510.

[0041] Using the above scheme: When the live shrimp to be transplanted passes laterally through the slot 590 in the middle of the tapered plate 540, its tail faces the injection hole 560, which lays the foundation for subsequent positioning. As the shrimp rotates, its back faces the vertical plate 100, allowing the shrimp to naturally position itself between the curved base plate 550 and the push plate 510, achieving good initial positioning. The activation of the cylinder 400 is crucial to the entire process. The output end of the cylinder 400 pushes the push plate 510 to slide forward along the inner side of the U-shaped frame 200. The arc segment on the lower side of the push plate 510 gradually approaches the tapered plate 540. This design cleverly utilizes the structure of the tapered plate 540, which is narrow at the bottom and wide at the top, so that the shrimp tail is guided to the narrow opening of the tapered plate 540 by the inertia of motion. As the shrimp tail becomes increasingly close to the tapered plate 540, initial positioning is achieved. Simultaneously, the light shield 530 fixed to the top of the push plate 510 also moves forward, effectively blocking strong external light and reducing the stress response of the shrimp caused by changes in light, creating a relatively comfortable environment for subsequent injection preparation. As the push plate 510 continues to move forward, a pair of arc-shaped plates 520 rotatably connected in the middle of the push plate 510 gradually contact the shrimp body. Since the curvature of the arc-shaped plates 520 is less than that of the arc-shaped base plate 550, and the outer wall of the arc-shaped plates 520 is elastically connected to the push plate 510, the arc-shaped plates 520 can adaptively conform to the back contour of the shrimp. This adaptive design not only improves the stability of the clamping but also effectively prevents damage to the shrimp body caused by improper fixation during the clamping process. During this process, the ends of the arc-shaped plates 520 slide on the arc-shaped base plate 550 and contract inward, forming a flexible clamping space together with the silicone air bladder 570. At this time, air is inflated into the silicone air bladder 570 through the air inlet pipe 580, and the air bladder expands between the arc-shaped plates 520, forming a stable clamping force on the shrimp body. The flexible squeezing force can be adjusted in real time according to the shrimp's struggles, ensuring that the shrimp will neither slip out nor suffer tissue damage due to excessive pressure. This design fully considers the physiological characteristics of live shrimp, greatly reducing the risks during operation.

[0042] like Figure 2 , Figures 7 to 9As shown, the auxiliary injection mechanism 600 includes a slide groove 620 formed on the lower side of the U-shaped frame 200. Slide strips 640 are fixedly connected to both sides of the bottom of the push plate 510, and first magnetic blocks 650 are fixedly connected to the ends of the slide strips 640. The slide strips 640 and the first magnetic blocks 650 are slidably connected within the slide groove 620. An arc-shaped groove 660 is formed on the lower side of the vertical plate 100. A hollow guide plate 610 is rotatably connected to the bottom of the U-shaped frame 200. The width of the hollow guide plate 610 is smaller than the arc-shaped groove. The width of the groove 660; a V-shaped groove 630 is opened on the top of the hollow guide plate 610; gears 670 are fixed to both sides of the hollow guide plate 610, and racks 680 mesh with the outer walls of the gears 670; a second magnetic block 690 is fixed to the side of the rack 680 near the first magnetic block 650, and the second magnetic block 690 and the first magnetic block 650 are magnetically attracted; an extension needle and an ultra-fine soft rubber needle are fixed to the top of the injection module 300, and the two slide through the injection hole 560.

[0043] The above scheme is adopted as follows: As the push plate 510 slides forward, the sliding strips 640 and the first magnetic block 650 fixed to both sides of the bottom of the push plate 510 move forward synchronously along the sliding groove 620. When the first magnetic block 650 moves to the position where it is magnetically attracted to the second magnetic block 690, the second magnetic block 690 will drive the rack 680 to slide along the side wall of the vertical plate 100. This action triggers the rotation of the gear 670, which drives the hollow guide plate 610 to rotate upward around its axis. The V-shaped groove 630 at the top of the hollow guide plate 610 gradually squeezes the shrimp tail scales, bringing the shrimp tail closer to the arc-shaped groove 660 on the lower side of the vertical plate 100. This design ensures that the opening of the shrimp's lower digestive tract can be accurately aligned with the injection hole 560. For smaller shrimp, the increased rotation angle of the hollow guide plate 610 further presses into the shrimp tail, making up for the distance difference between it and the arc-shaped groove 660, and avoiding squeezing damage caused by insufficient space. The flexibility and adaptability of this mechanism enable effective clamping and positioning of shrimp of different sizes, enhancing the equipment's versatility. Once the shrimp is fully secured and its tail is accurately positioned, the injection module 300 activates. Its extended needle and ultra-fine soft rubber needle extend from the injection hole 560 and are slowly inserted into the shrimp's lower digestive tract along the guide direction of the hollow guide plate 610. The ultra-fine soft rubber needle, made of a soft material, automatically conforms to the intestinal direction during insertion, reducing the risk of intestinal wall puncture. After the bacterial solution is injected, the cylinder 400 reverses its movement, the push plate 510 begins to retract, the silicone airbag 570 deflates, the arc-shaped plate 520 resets under elastic action, and the hollow guide plate 610 automatically resets and flips under the reverse transmission of the gear 670 and rack 680, releasing the shrimp tail. Throughout the process, the clamping action of the push plate 510 and the flipping action of the hollow guide plate 610 are synchronized through a magnetic linkage mechanism, requiring no additional power source and making operation simpler and more efficient. The precise coordination of this series of structures not only improves the success rate of live shrimp transplantation, but also reaches new heights in terms of operational efficiency, stability and safety, providing important reference and guidance for the future technological development of related fields.

[0044] Working principle and usage process of this invention:

[0045] In use, the live shrimp to be transplanted is passed through the slot 590 in the middle of the tapered plate 540 from the side, with the shrimp tail facing the injection hole 560. Then, the shrimp body is rotated so that its back faces the vertical plate 1 and it is placed between the curved base plate 550 and the push plate 510. The cylinder 400 is activated, and the output end of the cylinder 400 causes the push plate 510 to slide forward along the inner side of the U-shaped frame 200. The arc section on the lower side of the push plate 510 gradually approaches the tapered plate 540 without affecting the movement of the push plate 510. The tapered plate 540 is designed to be narrower at the bottom and wider at the top. Utilizing the shrimp's backward movement inertia, the shrimp tail is gradually guided to the narrow opening of the tapered plate 540, and the fit becomes tighter as it goes down, achieving the initial positioning of the shrimp tail. At the same time, the light shield 530 fixed to the top of the push plate 510 moves forward to block external light and reduce the stress response of the shrimp caused by strong light.

[0046] Secondly, as the push plate 510 continues to move forward, the pair of arc-shaped plates 520 rotatably connected in the middle of the push plate 510 gradually contact the shrimp body. Since the curvature of the arc-shaped plates 520 is less than that of the arc-shaped base plate 550, and the outer wall of the arc-shaped plates 520 is elastically connected to the push plate 510, the arc-shaped plates 520 adapt to the shrimp's back contour under elastic action. The ends of the arc-shaped plates 520 slide on the arc-shaped base plate 550 and contract inward, forming a flexible clamping space together with the silicone airbag 570. At this time, air is inflated into the silicone airbag 570 through the air inlet pipe 580. The silicone airbag 570 expands between the pair of arc-shaped plates 520, adjusting the flexible squeezing force according to the shrimp's struggle, and stably clamping the shrimp body, preventing the shrimp from slipping out and avoiding injury to the tissues.

[0047] Secondly, as the push plate 510 slides forward, the sliding strips 640 and the first magnetic block 650, which are fixed to both sides of the bottom of the push plate 510, move forward synchronously along the sliding groove 620. When the first magnetic block 650 moves to the position where it is magnetically attracted to the second magnetic block 690, the second magnetic block 690 drives the rack 680 to slide along the side wall of the vertical plate 100. The rack 680 drives the gear 670 to rotate, and the gear 670 drives the hollow guide plate 610 to rotate upward around its axis. The V-shaped groove 630 at the top of the hollow guide plate 610 gradually squeezes the shrimp tail scales, bringing the shrimp tail closer to the arc-shaped groove 660 on the lower side of the vertical plate 100, aligning the shrimp's lower digestive tract opening with the injection hole 560. If the shrimp is small, the rotation angle of the hollow guide plate 610 increases, further pressing the shrimp tail into the arc-shaped groove 660 to compensate for the distance difference and avoid squeezing damage.

[0048] Finally, once the shrimp body is completely fixed and the tail is accurately positioned, the injection module 300 is activated. Its extended needle and ultra-fine soft rubber needle extend from the injection hole 560 and are slowly inserted into the shrimp's lower digestive tract along the guide direction of the hollow guide plate 610. The ultra-fine soft rubber needle is made of a soft material and automatically conforms to the intestinal direction during insertion, avoiding puncture of the intestinal wall. After the bacterial solution is injected, the cylinder 400 moves in the reverse direction, causing the push plate 510 to retract. The silicone airbag 570 deflates, the arc-shaped plate 520 elastically resets, and the hollow guide plate 610 automatically resets and flips under the reverse transmission of the gear 670 and rack 680, releasing the shrimp tail. The second magnetic block 690 moves to a certain position and then locks into place, while the first magnetic block 650 continues to move and reset following the push plate 510. Throughout the process, the clamping action of the push plate 510 and the flipping action of the hollow guide plate 610 are synchronized through a magnetic linkage mechanism, requiring no additional power source and making operation simple and efficient.
