Description

Technical Field

[0001] The present invention relates to the technical field of magnetic anastomosis equipment, and more specifically to a magnetic anastomosis equipment for tissue clamping under digestive endoscopy. Background Art

[0002] With the development of medical technology, minimally invasive treatment technology under digestive endoscopy has gradually become the preferred option for the treatment of many digestive system diseases. Among them, the technology of using digestive endoscopy to control magnetic anastomosis equipment for tissue clamping has shown significant advantages in clinical applications. This technology is particularly suitable for patients who need temporary tissue clamping, such as in gastrointestinal fistula repair, perforation repair, endoscopic gastric bypass surgery and other situations that require temporary closure or connection of gastrointestinal tissues.

[0003] In the process of using a magnetic anastomosis device for temporary tissue clamping, it is first necessary to select a magnetic anastomosis device of appropriate size according to the treatment needs of different patients, and then send the magnetic anastomosis device to the target position through a digestive endoscope. After accurately locating the target tissue with the camera on the endoscope, the adjustment module on the release mechanism can be used to fine-tune the magnetic element to ensure that it is accurately adsorbed on the target tissue, and then the magnetic element is unlocked by the release handle so that it is tightly combined with the target tissue.

[0004] Although the technology of using digestive endoscopy to control magnetic anastomosis equipment for tissue clamping has made significant progress in clinical practice, there are still some challenges, especially the problem that the magnetic anastomosis equipment cannot be effectively adjusted after placement and clamping. This is because in actual operation, after the magnetic anastomosis equipment releases the magnetic element, once the magnetic element is adsorbed on the target tissue, it is difficult to adjust the position. Most of the magnetic elements are in the shape of an integrated ring, which may cause some areas on the magnetic ring to fail to be accurately adsorbed at the optimal position, thereby affecting the temporary closure treatment effect. Therefore, it is necessary to provide a magnetic anastomosis device for tissue clamping under digestive endoscopy. Summary of the invention

[0022] Magnetic drive can avoid possible jamming or overload problems in mechanical drive, thereby improving safety during temporary clamping. Magnetic drive has a fast response time, which is different from mechanical drive adjustment. Not only does it produce smaller feedback of motion effects to improve patient comfort, but it is also non-contact and does not require lubrication, which can reduce maintenance costs and complexity.

[0023] In the process of cooperating to adjust the position of the adjustable magnetic block mechanism through the inner ring magnetic adjustment ring mechanism and the outer ring magnetic adjustment ring mechanism, it can also control the position of the pull plate by pulling the pull wire through the square sleeve block, and can control the pull plate to pull the film upward. When the fourth magnetic block is lifted upward to cancel the clamping state, the tissue at the corresponding end can be pulled, so that the tissue at the clamped end can be fine-tuned for a second time, further improving the flexibility and controllability of the magnetic element.

[0056] Among them, the configured visible circular partition 63 and the circular cover 61 are an integrated structure, specifically, a visible circular partition 63 is configured on the surface of the circular cover 61, which can cooperate with the camera end on the release structure for real-time detection, and the first circular opening 47 passing through the first guide rail circular frame 44 and the second circular opening 49 passing through the second guide rail circular frame 48 are specifically opened on the two circular frames.

[0057] like Figures 3 to 6 As shown, an arc guide groove 410 is provided on the upper and lower edge surfaces of the first guide ring frame 44 and the second guide ring frame 48, and an inner ring magnetic adjustment ring mechanism 8 is movably configured inside the first guide ring frame 44, and the inner ring magnetic adjustment ring mechanism 8 includes a first engaging ring 81, and the upper and lower edge surfaces of the first engaging ring 81 are fixedly installed with a first limiting convex buckle 82 that slides in the arc guide groove 410 of the first guide ring frame 44, and a first buffer bottom plate 83 is fixedly installed on the outer edge surface of the first engaging ring 81 at the position corresponding to each side of the linear guide frame 45, and a plurality of fifth magnetic blocks 84 with gradually weakening magnetic properties are fixedly installed on the surface of the first buffer bottom plate 83 in sequence.

[0058] like Figures 3 to 8As shown, an outer ring magnetic adjustment ring mechanism 9 is movably configured on the second guide rail ring frame 48, and the outer ring magnetic adjustment ring mechanism 9 includes a second locking ring 91, and the upper and lower edge surfaces of the second locking ring 91 are fixedly installed with second limiting protrusions 92 that slide and are locked in the arc guide groove 410 of the second guide rail ring frame 48, and a second buffer bottom plate 93 is fixedly installed at the position of each side linear guide frame 45 on the outer edge surface of the second locking ring 91, and a plurality of sixth magnetic blocks 94 with gradually weakening magnetic properties are fixedly installed on the surface of the second buffer bottom plate 93 in sequence.

[0059] like Figures 3 to 8 As shown, the second magnetic blocks 72 are fixedly installed on the two side surfaces of the square sleeve block 71 facing the first circular opening 47 and the second circular opening 49; and the second magnetic blocks 72 on each side are magnetically repelled from the fifth magnetic blocks 84 and the sixth magnetic blocks 94 on the corresponding side circular opening ends, and the release module contact tube 3 is installed on the outer sides of the first wiring block 62, the first limiting protrusion 82, and the second limiting protrusion 92.

[0060] Among them, the configured release module touch tube 3 is a touch tube structure installed on the release module in the prior art, and the release module is a structure used to release the magnetic element in the prior art, which generally includes a handle used by the doctor to control the release of the magnetic element, an adjustment module to ensure that the magnetic element remains fixed during the transportation process, and an indicator showing the status of the magnetic element, while the touch tube is a tubular structure connected to the release end, which is a slender hose as a whole, used to deliver the magnetic element into the digestive tract, and is used in conjunction with the push rod, which are all conventional configurations in the prior art.

[0061] The specific working state of the adjustable magnetic block mechanism 7 is:

[0062] Pre-adjustment stage: according to the needs, the release module touch tube 3 set on the first limit convex buckle 82 and the second limit convex buckle 92 can be used to pull the inner ring magnetic adjustment ring mechanism 8 and the outer ring magnetic adjustment ring mechanism 9 respectively. Since the magnetic force of the fifth magnetic block 84 on the outer ring of the first engaging ring 81 movably clamped in the first guide rail circular ring frame 44 gradually weakens, the magnetic force of the second engaging ring 91 movably clamped in the second guide rail circular ring frame 48 also gradually weakens, and both are aligned with the second magnetic block 72 on the square sleeve block 71 through the first circular opening 47 and the second circular opening 49 on the corresponding side, it is only necessary to adjust the first engaging ring 81 and the second engaging ring 91 separately, and slide on the arc guide The first limiting convex buckle 82 and the second limiting convex buckle 91 in the notch 410 can change their respective positions, so that the fifth magnetic block 84 and the sixth magnetic block 94 with different magnetic forces can be aligned with the second magnetic blocks 72 on the front and rear sides of the square sleeve block 71, so that the square sleeve block 71 changes its current position. If the magnetic force of the fifth magnetic block 84 is stronger than that of the sixth magnetic block 94, the square sleeve block 71 will move along the linear guide frame 45 to the outer end of the circular frame 41, otherwise it will move to the inner end of the circular frame 41 to change the position of the square sleeve block 71. The change in the position of the square sleeve block 71 can synchronously adjust the position of each fourth magnetic block 75 to change the inner diameter of the magnetic end of the magnetic element.

[0063] Second fine-tuning stage: After the release module touch tube 3 is used to control the release of the first magnetic element 1 and the second magnetic element 2 into the digestive tract, after they enter the designated position, the groups of fourth magnetic blocks 75 on the two elements will be adsorbed and fitted to temporarily clamp the position. When it is necessary to fine-tune a certain area of ​​the temporary clamping end again, it is only necessary to pull the release module touch tube 3 set on the first wiring block 62 to control the circular cover plate 61 that is movable on the upper side of the circular frame 41 to rotate through the release module touch tube 3. During the rotation of the circular cover plate 61, the first magnetic block 64 on the bottom surface thereof will also During the synchronous rotation, in the process of rotating around the adjustment area 42, since the first magnetic block 64 and the third magnetic block 74 on the upper side of the plug rod 73 of the square sleeve block 71 are mutually attracted, the first magnetic block 64 will be attracted to the third magnetic block 74 at this position when the third magnetic block 74 is aligned with the third magnetic block 74 on the corresponding side, and the plug rod 73 is movably installed on the square sleeve block 71, and the upward lifting of the third magnetic block 74 will drive the synchronous upward movement of the fourth magnetic block 75, so that the fourth magnetic block 75 in the adsorption state on the first magnetic element 1 and the second magnetic element 2 will be separated, thereby canceling the clamping state at this position;

[0064] Among them, since the first magnetic element 1 and the second magnetic element 2 are extended into the patient's interior through the release module contact tube 3 on the release module, and the release module is provided with a corresponding camera end to provide real-time feedback of the internal situation, and with the help of the camera end and the visible circular ring partition 63 of the circular ring cover 61, the internal situation of the circular ring frame 41 can also be observed, so as to facilitate the control of the fourth magnetic suction block 75 on the corresponding side to lift up to cancel the clamping state of the corresponding side.

[0068] Among them, the fourth magnetic block 75 of the adjustable magnetic block mechanism 7 at the corresponding position on the circular frame 41 is lifted upward, and after the clamping state of the corresponding side is cancelled, the film 56 in the secondary fine-tuning mechanism 5 can also be pulled by the adjustable magnetic block mechanism 7 to perform secondary fine-tuning, and the specific steps are as follows: first, the first magnetic block 64 at the bottom of the circular cover plate 61 is aligned with the fourth magnetic block 75 on the corresponding side, and after it is lifted, the inner ring magnetic adjustment ring mechanism 8 and the outer ring magnetic adjustment ring mechanism 8 can be adjusted again by the release module contact tube 3 configured on the first limiting convex buckle 82 and the second limiting convex buckle 92. The relative position of the structure 9 makes the square sleeve 71 close to the outermost inner wall of the circular frame 41, and the other end of the pull wire 511 is connected to the square sleeve 71. When the square sleeve 71 is expanded outward, it will pull the film 56 at the bottom of the pull plate 57, so that the film 56 moves upward along the first square notch 52 and the second limiting notch 54 on the second square notch 53. The bottom of the film 56 is in contact with the tissue layer of the patient. Therefore, when the film 56 is pulled upward, the tissue layer on the corresponding side will also be pulled, so that the tissue layer at this position is finely adjusted for the second time.

[0069] Among them, the limiting baffles 58 arranged at the first square slot 52 and the second square slot 53 are used to limit the film 56 outward so that the film 56 can move at the edge position of the bottom of the circular tray rack 51 to effectively pull the tissue layer at this position. The configured pulling plate 57 is specifically slidably stuck in the second limiting slot 54 on the vertical side.

[0070] The working process of the technical solution of the present invention is as follows:

[0071] First, the first limiting convex buckle 82 and the second limiting convex buckle 92 on the inner circle magnetic adjustment ring mechanism 8 and the outer circle magnetic adjustment ring mechanism 9 are pulled by the release module contact tube 3 to make the first engaging circular ring 81 and the second engaging circular ring 92 rotate accordingly, and change the position of the fifth magnetic block 84 and the sixth magnetic block 94 on one end of the second magnetic block 72 facing the surface of the square sleeve block 71. According to the corresponding magnetic force, the position of the square sleeve block 71 is adjusted, and the position of the fourth magnetic block 75 is changed to change the inner diameter of the entire magnetic element. Furthermore, the third magnetic block 74 can be adsorbed on the first magnetic block 64 by the rotating circular cover plate 61 to release the fourth magnetic block 75 on the corresponding side, and the square sleeve block 71 is cooperated to pull the pull plate 57 upward, so that the film 56 in the secondary fine-tuning mechanism 5 pulls the tissue layer, so that the tissue layer at this position is fine-tuned for the second time.
